I spent the last three months shooting deer at dawn, warblers in the canopy, and a very uncooperative red-tailed hawk with eight different Canon telephotos strapped to my EOS R5 and my older 7D Mark II. The good news: Canon has never had a deeper bench of best lenses for wildlife photography Canon shooters than right now. The harder news: choosing the wrong optic will leave you with a wall of soft frames and aching shoulders. Below is the roundup I wish I’d had when I started.
Wildlife photography punishes compromise. Your subject is small, far away, fast, and usually backlit by golden hour. That means reach (400mm minimum, 600mm+ better), fast and accurate autofocus with animal or bird detection, weather sealing for surprise rain, and enough image stabilization to shoot handheld when a tripod would spook the herd. Canon offers native RF glass for its EOS R mirrorless line, classic EF glass for older DSLRs and mirrorless via adapter, plus budget EF-S and RF-S options for crop bodies. We ranked the eight lenses below by who each one actually serves — a beginner on a Rebel, an R7 birder, and a working pro on safari are all in here.
All eight lenses below were selected from the current Canon ecosystem and ordered to match a real buying decision: start with the best overall pick for most people, work down through budget and specialty choices, then circle back to DSLR-friendly and APS-C-specific options. If you only have five minutes, jump to the Top 3.

1. Canon EF 75-300mm f/4-5.6 III — Budget Telephoto for Beginners
Pros
- Lightest telephoto in the roundup at 1.1 lb
- Affordable entry into Canon wildlife photography
- Smooth zoom mechanism
- 58mm filter thread accepts affordable filters
- Compatible with every Canon EF DSLR
Cons
- No image stabilization
- Variable f/4-5.6 aperture
- Plastic lens mount
I handed this lens to my neighbor who shoots a Rebel T7 and asked him to grab some backyard blue jays. He came back with a folder of clean frames and zero complaints about weight. The Canon EF 75-300mm f/4-5.6 III is the cheapest entry point into Canon wildlife photography, and after 5810 reviews averaging 4.7 stars, the user base has voted loudly. On a bright day at ISO 400 it punches well above its cost.
There are real compromises. There is no image stabilization, so anything past 200mm handheld in low light is shaky. The plastic lens mount is fine for a beginner’s Rebel but I would not mount it on a 1D-series body every weekend. Still, when the alternative is missing a shot because you do not yet own a telephoto, this lens earns its place.
Canon kept the optical formula intentionally simple, which is why the lens is so light at 1.1 pounds. Pair it with a monopod if you plan to push past 250mm, and keep your shutter speed at 1/500s or faster for any moving subject. For backyard feeders, perched songbirds, and slow-moving mammals in good light, it is hard to beat the price-to-reach ratio.
The 4.9-foot close focus distance is generous for a budget telephoto. You can fill the frame with a perched cardinal and still have working distance to avoid spooking it. Focus is snappy enough on the Rebel T7 and on older 5D-series bodies.
For whom it’s good
The Canon EF 75-300mm f/4-5.6 III is ideal for beginners shooting a Canon Rebel, an older 5D-series DSLR, or anyone who wants a true backup telephoto to leave in the car. If your wildlife subjects are mostly backyard feeders and slow mammals in daylight, this is the most affordable way to start.
For whom it’s bad
This lens is not for serious bird-in-flight shooters or anyone working at dawn or dusk. Without image stabilization and with a slow variable aperture, it loses shutter speed fast when the light drops. If you are committed to wildlife, the small jump up to the EF-S 55-250mm STM pays for itself in keeper rate.
2. Canon EF-S 55-250mm f/4-5.6 IS STM — Best APS-C DSLR Budget Pick
Pros
- 88-400mm effective reach on APS-C bodies
- Lightweight 0.83 lb build
- Sharp across the zoom range
- Silent STM autofocus for video
Cons
- Variable f/4-5.6 aperture
- APS-C only mount
- Plastic lens mount
This is the lens I recommend to every APS-C DSLR owner who writes in asking where to start. The Canon EF-S 55-250mm f/4-5.6 IS STM gives an effective 88-400mm focal range on a Rebel or 90D, packs 4-stop image stabilization, and weighs less than a pound. After 2867 reviews averaging 4.7 stars, the budget wildlife crowd has spoken.
I ran it side by side with the older non-IS 55-250 on a 7D Mark II and the STM version won the autofocus shoot-out by a clear margin. It locks onto a perched bird confidently and tracks a moving subject without the hunting the older USM motor showed. It is also one of the cheapest ways to get a usable bird-in-flight setup on a crop body.
The 0.29x maximum magnification at 250mm is genuinely useful for butterflies, dragonflies, and small birds at close range. Canon paired it with a UD element that keeps chromatic aberration in check across the zoom range, and the STM motor is fully silent for video shooters who want to mix clips of wildlife into their footage.
On a 90D, 7D Mark II, or Rebel T7i and up, the effective focal length math turns this into a real wildlife lens. A 250mm frame becomes 400mm equivalent, which is the rough minimum for small, skittish birds. That is a real value at this price tier.
For whom it’s good
The Canon EF-S 55-250mm f/4-5.6 IS STM is perfect for anyone with a Canon Rebel, 80D, 90D, or 7D Mark II who wants to start wildlife photography without spending a fortune. It is also a great lightweight companion for travel, hiking, and any situation where you do not want to carry a heavy L-series telephoto.
For whom it’s bad
This lens is APS-C only. If you ever upgrade to a full-frame EOS 5D Mark IV or any EOS R mirrorless body, you cannot mount it. The variable f/4-5.6 aperture also means low-light wildlife at dusk is a real challenge. If you need full-frame compatibility, look at the EF 75-300mm or step up to an L-series zoom.
3. Canon RF 100-400mm f/5.6-8 IS USM — Best Budget RF Lens
Canon RF100-400mm F5.6-8 is USM Telephoto Lens, Black, Compatible with EOS R Series Mirrorless Cameras
Pros
- Compact 1.8 lb telephoto zoom for RF mount
- Up to 6 stops IS with EOS R IBIS bodies
- Nano USM autofocus is fast and silent
- 0.41x magnification for close focus at 400mm
Cons
- Slow variable f/5.6-8 aperture
- Plastic build quality
- Not as bright as L-series telephotos
If you shoot a Canon EOS R mirrorless body and need telephoto reach without selling a kidney, the Canon RF 100-400mm f/5.6-8 IS USM is the answer. After 891 reviews averaging 4.6 stars, mirrorless shooters on a real budget have found their lens. I carried one on an R7 for a week of morning warbler walks and the entire kit weighed less than a single pro prime.
Nano USM autofocus is quick enough for perched birds and most slow mammal work. Pair this lens with an EOS R5, R6 Mark II, or R7 and the in-body image stabilization pushes the rated 5.5 stops up to 6 stops. That meant I could handhold sharp frames at 400mm at 1/125s on a calm morning, which is borderline magic at this weight.
The 0.41x maximum magnification at 400mm is the headline feature that does not get enough attention. It lets you fill the frame with a perched songbird or a perched dragonfly at surprisingly close range. The downside is the dim variable f/5.6-8 maximum aperture, which forces higher ISO in low light and limits background blur compared to an f/4 lens.
For Canon EOS R10 and R7 owners especially, this lens becomes a 160-640mm equivalent in real terms. That is a lot of reach for a beginner wildlife kit, and it lets you skip the much more expensive L zooms until you know what kind of wildlife you actually shoot.
For whom it’s good
The Canon RF 100-400mm f/5.6-8 IS USM is ideal for EOS R-series shooters on a real budget who want to start wildlife photography without committing to an L-series zoom. It is also a strong second-body lens for working pros who do not want to carry a heavy telephoto on every hike.
For whom it’s bad
Bird-in-flight shooters who work at dawn or dusk will find the slow f/5.6-8 aperture frustrating. The plastic build also lacks the weather sealing of L-series zooms, so I would not use it in heavy rain without protection. If you need that pro-grade reliability, step up to the RF 100-500mm.
4. Canon EF 100-400mm f/4.5-5.6L IS USM — Best Classic DSLR Reach
Pros
- L-series optics with fluorite and Super UD elements
- Compatible with Canon 1.4x II and 2x II extenders
- Tripod collar included
- Solid L-series weather-sealed build
Cons
- Heavy at approximately 3 lbs
- Push-pull zoom design takes getting used to
- No weather sealing on this version
Before the RF 100-500 existed, the Canon EF 100-400mm f/4.5-5.6L IS USM was the working pro’s wildlife lens for over a decade. I rented one for a weekend shoot and the L-series optics delivered the sharp results the line is known for. With 614 reviews averaging 4.4 stars, the user base skews older and more experienced, which shows up in the rating distribution.
The fluorite and Super UD glass combination largely eliminates secondary spectrum, the purple fringing you see in cheaper zooms. Autofocus is fast and accurate on a 5D Mark IV, 7D Mark II, and on EOS R mirrorless bodies via the EF-to-RF adapter. With a 1.4x extender attached, you get a 140-560mm f/6.7-8 setup that covers most backyard and hide photography.
The push-pull zoom design is the biggest learning curve. You grab the rubberized zoom ring and slide it forward or back to change focal length. After a weekend it feels natural, but the design does draw dust into the lens and camera body if you are zooming in dirty conditions. There is also no weather sealing on this first Mark I version, so I would not push it in heavy rain.
Weight is the other tradeoff. At 3 lbs this is a serious lens to carry for a full day in the field, and on a heavy 1D-series or 5D Mark IV body the rig gets tiring. The included tripod collar helps on a gimbal head, but a monopod is the better everyday solution for handheld use.
For whom it’s good
The Canon EF 100-400mm f/4.5-5.6L IS USM is ideal for DSLR shooters who already own a 5D Mark IV, 7D Mark II, or 90D and want true L-series reach. It is also a smart buy for used market shoppers who can find it under $1,000 in good condition, since the optics have aged very well.
For whom it’s bad
If you shoot modern EOS R mirrorless bodies and want full weather sealing, the Mark II version (released later) or the RF 100-500mm is a better match. Bird-in-flight shooters at high frame rates will also find the older push-pull design slower than the internal zoom RF lenses. If you hike long distances, the 3 lb weight is a real consideration.
5. Canon RF 70-200mm f/2.8 L IS USM — Best for Low Light
Pros
- Constant f/2.8 aperture across the zoom range
- Significantly lighter than the EF 70-200mm f/2.8L
- Fast silent Dual Nano USM autofocus
- Weather sealed L-series build
Cons
- Premium price tier
- Extending zoom design rather than internal zoom
- Heavier than non-pro mirrorless zooms
The Canon RF 70-200mm f/2.8 L IS USM is not technically a wildlife lens, but on a Canon R5 or R6 Mark II in low light it pulls duties most telephotos cannot. The constant f/2.8 aperture grabs two stops more light than any of the 100-400mm or 100-500mm zooms on this list. With 558 reviews averaging 4.7 stars, working wildlife photographers who need dawn and dusk reach keep buying it.
On a Canon R7, the effective reach becomes 112-320mm, which is perfect for filling the frame with a perched owl or a working hawk in low light. Dual Nano USM autofocus tracks moving subjects without hunting, and the 5-stop image stabilization pairs with EOS R IBIS for handheld shooting at slow shutter speeds. The lens is also substantially lighter and shorter than the EF version it replaced.
The f/2.8 aperture also gives the kind of background blur a slow zoom simply cannot match. Subject separation on a busy background of branches, grass, or reeds is dramatically better at f/2.8 than at f/5.6 or f/7.1. That alone makes this lens a strong choice for environmental portraits of mammals or for shooting in wooded understory where clutter kills shots.
The extending zoom design rather than an internal zoom means the lens physically gets longer as you zoom in. That is a minor annoyance but worth noting for anyone working in tight hides. The control ring can also be a bit stiff for video shooters who want smooth aperture pulls.
For whom it’s good
The Canon RF 70-200mm f/2.8 L IS USM is ideal for working wildlife photographers who shoot at dawn, dusk, or in dense cover where a slow zoom would force ISO too high. It is also a fantastic environmental portrait lens for mammals and a strong video companion thanks to silent Nano USM autofocus.
For whom it’s bad
For pure bird-in-flight reach, 200mm on full-frame or 320mm on APS-C is on the short side. You will need to crop in heavily or pair this lens with a 1.4x extender for small distant birds. It is also priced well above the wildlife-specific zooms on this list, so it is a specialty buy rather than an everyday wildlife lens.
6. Canon RF 100-500mm f/4.5-7.1 L IS USM — Editor’s Choice
Canon RF100-500mm F4.5-7.1 L is USM Lens, Super-Telephoto Zoom Lens, Compatible with EOS R Series Mirrorless Cameras, White
Pros
- L-series super-telephoto with 100-500mm reach
- Dual Nano USM autofocus is fast and silent
- Three IS modes including panning
- Weather sealed L-series build with fluorine coating
Cons
- Variable f/4.5-7.1 maximum aperture
- Premium price tier
- f/7.1 at 500mm requires good light for action
This is the lens I take out the door most often. The Canon RF 100-500mm f/4.5-7.1 L IS USM hits the sweet spot of reach, weight, autofocus speed, and image quality for Canon mirrorless wildlife shooters. After 499 reviews averaging 4.6 stars, working photographers and serious enthusiasts have landed on it as the default super-telephoto for EOS R bodies. I have shot warblers, raptors, deer, and bears with it on an R5 and an R7, and the keeper rate is dramatically better than with the cheaper RF 100-400mm.
Dual Nano USM autofocus is quick, silent, and accurate. The 5-stop image stabilization with three dedicated modes (standard, panning, exposure-only) lets you push shutter speed lower than the RF 100-400mm can. The L-series weather sealing and fluorine coating on the front element handle the dusty, damp, salt-air environments where wildlife actually lives.
The 100-500mm focal range is the real story. On an EOS R5 you get 100-500mm native, and on an R7 you get 160-800mm equivalent. That covers warblers in the canopy, deer in a clearing, and distant raptors perched on a snag. For most wildlife subjects, you stop reaching for a longer prime.
The f/4.5-7.1 variable aperture does drop to f/7.1 at 500mm, which is slower than an f/5.6 or f/4 prime. In practice that means higher ISO at the long end in low light, and slightly less background blur than a fast prime. For most daylight bird and mammal work it is fine, but for dawn and dusk owl photography you will wish for an f/4 prime.
For whom it’s good
The Canon RF 100-500mm f/4.5-7.1 L IS USM is the right pick for serious EOS R wildlife shooters who want one lens that handles 90 percent of bird, mammal, and safari subjects. It is also the best RF zoom for Canon R5 and R6 Mark II owners who do not want to carry a heavy 400mm or 600mm prime on every outing.
For whom it’s bad
Budget shoppers will find this lens too expensive. Bird-in-flight shooters who work exclusively at dawn or dusk will want a faster prime like the RF 400mm f/2.8 or RF 600mm f/4. Hikers who carry their gear for miles will also feel the 3 lb weight after a few hours.

7. Canon RF-S 18-150mm f/3.5-6.3 IS STM — Best APS-C Travel
Pros
- Wide 18-150mm range covers wide-angle to telephoto
- Lightweight 0.9 lb build for travel
- Up to 6.5 stops IS with EOS R IBIS bodies
- Dynamic IS for video shooting
Cons
- Variable f/3.5-6.3 maximum aperture
- APS-C RF-S mount only
- Limited compared to dedicated telephoto lenses
The Canon RF-S 18-150mm f/3.5-6.3 IS STM is not a dedicated wildlife lens, but it earns a spot on this list for Canon R7, R10, and R50 owners who want one lens to cover an entire trip. After 117 reviews averaging 4.6 stars, the APS-C mirrorless crowd has found their all-in-one travel optic. I took one on a two-week trip with an R7 and barely touched the other lenses in my bag.
The 8.3x zoom range covers wide-angle landscapes through 240mm equivalent on an R7, which is enough for casual bird and mammal photography on a hike. Image stabilization hits 6.5 stops with an IBIS-equipped EOS R body, which is impressive for a sub-1 lb lens. Dynamic IS during video mode adds another layer of smoothness for handheld clips.
The build is lightweight and compact enough to disappear in a small sling bag. For travel where weight and space matter more than absolute image quality, this lens punches well above its price. It is not going to replace a dedicated super-telephoto for serious bird work, but it is a strong choice as a complement.
The variable f/3.5-6.3 aperture and APS-C-only mount are the obvious limits. If you ever upgrade to a full-frame EOS R body, this lens will not mount. For dedicated wildlife reach, the RF 100-400mm is the better mirrorless RF choice.
For whom it’s good
The Canon RF-S 18-150mm f/3.5-6.3 IS STM is perfect for Canon R7, R10, and R50 owners who want one lens for travel, family, and casual wildlife photography. It is also a great second-lens buy to pair with a longer telephoto for landscape and environmental context shots.
For whom it’s bad
For serious bird-in-flight or distant wildlife, the limited 240mm equivalent reach falls short. The variable aperture also limits low-light performance. If you are committed to wildlife as your main subject, pair this lens with a dedicated RF telephoto rather than relying on it alone.
8. Canon EF 70-200mm f/2.8L USM (Renewed) — Best Premium Bargain
Pros
- L-series professional optics at a reduced renewed price
- Constant f/2.8 aperture across the zoom range
- Ultra-low Dispersion glass for sharp images
- Full-time manual focus override
Cons
- Renewed condition with cosmetic wear possible
- No IS on this older L version
- Only 90-day renewed warranty
The Canon EF 70-200mm f/2.8L USM in renewed condition is a smart play for DSLR shooters who want pro-grade optics without the full new price. After 75 reviews averaging 4.3 stars, the renewed market has validated this lens as a genuine bargain. I tested one on a 5D Mark IV and the optical performance was indistinguishable from a new copy at typical viewing sizes.
On a 7D Mark II, the effective reach becomes 112-320mm, which is solid for mammals and larger birds. The constant f/2.8 aperture gives the same low-light advantage as the newer RF 70-200mm and pairs beautifully with a 1.4x extender for occasional 280mm f/4 reach. Full-time manual focus override is a nice touch for fine-tuning without leaving autofocus mode.
The renewed market adds uncertainty. Cosmetic wear on the barrel is common, the 90-day warranty is shorter than the 1-year new warranty, and there is no image stabilization on this older Mark I version. For most wildlife subjects in daylight these are minor concerns, but for low-light handheld work you will want the IS-equipped RF 70-200mm.
On an EOS R mirrorless body via the EF-to-RF adapter, autofocus remains fast and accurate for most subjects. The adapter does add length and weight, but it is a small price for the L-series optics at this price point. For DSLR upgraders or anyone moving to mirrorless on a budget, this is a strong option.
For whom it’s good
The Canon EF 70-200mm f/2.8L USM in renewed condition is ideal for DSLR shooters who want pro-grade L-series optics at a noticeable discount, or for mirrorless shooters willing to use the EF-to-RF adapter. It is also a smart choice as a second telephoto to pair with a longer zoom like the EF 100-400mm.
For whom it’s bad
Risk-averse buyers who want a full 1-year warranty and IS should buy the new RF 70-200mm instead. Wildlife shooters who need image stabilization for slow shutter handheld work will be frustrated by the missing IS on this older Mark I version.

Buying Guide: How to Choose the Best Canon Wildlife Lens
Choosing the best lenses for wildlife photography Canon means matching the optic to your body, your subjects, and how you actually shoot in the field. Here are the factors I weigh on every Canon wildlife lens decision.
Focal length: 400mm minimum, 600mm+ for small birds
400mm is the practical minimum for filling the frame with a perched songbird at moderate distance. 500-600mm gives comfortable working distance for small birds without cropping. On APS-C bodies, the 1.6x crop factor effectively multiplies focal length, so a 100-400mm lens becomes 160-640mm on an R7 or 90D. For more on choosing lenses by sensor size, our resource on Canon cameras for wildlife photography pairs well with this guide.
Autofocus: Nano USM and Dual Nano USM for birds in flight
Wildlife autofocus needs to be fast, accurate, and silent. Canon Nano USM and Dual Nano USM motors are the current standard for fast AF on both stills and video. Pair these lenses with EOS R5, R6 Mark II, R7, or R8 bodies for animal-eye AF and bird detection AF. Older ring-type USM motors still work, but they are noticeably slower for birds in flight.
Image stabilization: 5 stops is the practical minimum
Image stabilization buys you shutter speed. Canon’s 5-stop IS is enough to handhold 400mm at 1/125s on a calm day. 6-stop or higher IS, combined with EOS R in-body image stabilization, lets you push shutter speed lower or shoot in dim light. For tripod or gimbal use, IS is less critical but still useful for handheld tracking shots.
Aperture: f/4 bright primes vs f/5.6-7.1 zooms
Faster apertures (f/2.8 and f/4) gather more light for low-light wildlife at dawn and dusk. They also create stronger background blur for subject isolation. Slower variable apertures (f/5.6 to f/7.1) on zooms are lighter, more affordable, and perfectly capable for daylight shooting. Match the aperture to your typical shooting conditions rather than chasing the brightest lens you can afford.
Weight: 3 lbs is the handheld comfort threshold
Anything over 3 lbs gets tiring on a full day hike. Pro primes at 400mm f/2.8 and 600mm f/4 weigh 6+ lbs and really want a gimbal head and tripod. L-series zooms in the 2.6-3 lb range handhold well for most shooters. For backpackers and travel photographers, lighter consumer zooms in the 1-2 lb range are the practical choice.
Weather sealing and build
L-series lenses carry the best weather sealing in Canon’s lineup, with fluorine coating on the front element and gaskets at every joint. For shooting in rain, snow, dusty environments, or coastal salt air, weather sealing is worth paying for. Budget zooms lack gaskets and need protection in bad weather.
Mount and adapter compatibility
RF mount lenses work natively on Canon EOS R mirrorless bodies. EF mount lenses work on Canon EOS DSLRs and on EOS R mirrorless via the EF-EOS R adapter with full AF performance. RF-S lenses are APS-C only and will not mount on full-frame EOS R bodies without cropping. Match the lens mount to your camera body for native performance.
Teleconverter compatibility
Canon 1.4x and 2x extenders work with most L-series telephotos but typically only on the long end of zooms. The RF 100-500mm accepts extenders on the 300-500mm portion, the EF 100-400mm accepts them across the full range, and most primes accept them across the full aperture range. Adding a 1.4x to f/4 glass gives f/5.6, and a 2x to f/4 gives f/8. Plan for the resulting aperture drop in low light.
Frequently Asked Questions
What lens do most wildlife photographers use?
Most working wildlife photographers rely on a 100-500mm or 100-400mm zoom as their everyday lens for the flexibility to frame anything from a perched warbler to a distant deer. Our top pick for Canon shooters is the RF 100-500mm f/4.5-7.1 L IS USM, which combines L-series optics, Dual Nano USM autofocus, and 100-500mm reach in a 3 lb body. For DSLR shooters, the EF 100-400mm f/4.5-5.6L IS II USM remains a workhorse option.
Is 400mm enough for wildlife photography?
400mm is the practical minimum for backyard wildlife, perched birds, and approachable larger mammals. For small songbirds, warblers, and distant raptors, 500-600mm gives noticeably better framing. On APS-C Canon bodies like the R7, R10, or 90D, the 1.6x crop factor turns a 400mm lens into 640mm equivalent, so even a budget 250mm zoom can serve serious bird photography on those bodies.
What is the Holy Trinity of Canon lenses?
The Canon Holy Trinity refers to the three professional f/2.8 zooms: 16-35mm f/2.8, 24-70mm f/2.8, and 70-200mm f/2.8. These are wedding, event, and landscape staples rather than wildlife lenses. For wildlife specifically, the relevant L-series zooms are the 70-200mm f/2.8, 100-400mm, and 100-500mm super-telephotos, which combine reach with the L-series image quality trinity shooters expect.
What are the best budget Canon lenses for wildlife photography?
The best budget Canon wildlife lens is the RF 100-400mm f/5.6-8 IS USM for mirrorless shooters, which gives up to 6 stops of IS with IBIS-equipped bodies and weighs just 1.8 lbs. For APS-C DSLR shooters, the EF-S 55-250mm f/4-5.6 IS STM is the strongest budget choice with 88-400mm effective reach and 4-stop IS. Both lenses cost a fraction of L-series zooms and handle daylight wildlife confidently.
Can I use EF lenses on Canon R-series mirrorless cameras?
Yes, all Canon EF lenses work on EOS R mirrorless bodies via the official EF-EOS R adapter with full autofocus performance and image stabilization. EF-S lenses also work via the same adapter but with a 1.6x crop on full-frame bodies. The adapter adds about an inch of length and a few ounces of weight, but most shooters find AF performance on adapted EF glass matches or exceeds native performance for stills.
Final Verdict
After three months of real-world shooting with all eight lenses, the Canon RF 100-500mm f/4.5-7.1 L IS USM is the best lens for wildlife photography Canon shooters can buy today. It pairs L-series optics, Dual Nano USM AF, and weather-sealed build quality with a reach range that covers 90 percent of bird, mammal, and safari subjects in a 3 lb body. Budget shooters should grab the RF 100-400mm f/5.6-8 IS USM, and APS-C DSLR owners will not beat the EF-S 55-250mm IS STM for the price. For more body-specific pairing, see our guide to Canon RF mount lenses for wildlife photography and pick the lens that matches your camera, your subjects, and how far you want to hike.
