I’ve spent countless hours in the field testing both the Sony 70-350mm and 70-300mm lenses, and I’m here to tell you that choosing between these two telephoto powerhouses isn’t as straightforward as you might think. When I first started comparing these lenses, I thought it would be a simple decision based on focal length alone, but after months of real-world shooting, I discovered there’s so much more to consider.
Whether you’re shooting wildlife, sports, or just want that perfect compressed portrait, the right telephoto lens can make or break your shot. I’ve used both lenses extensively on various Sony camera bodies, from the a6400 to the a7R IV, and I’m excited to share my findings with you.
In this comprehensive comparison, I’ll break down every aspect you need to consider: build quality, optical performance, autofocus capabilities, real-world usage scenarios, and much more. By the end of this article, you’ll know exactly which lens deserves a spot in your camera bag.
Quick Overview: At a Glance
Before we dive deep into the nitty-gritty details, let me give you a quick snapshot of what each lens brings to the table:
Sony E 70-350mm f/4.5-6.3 G OSS:
- Designed specifically for APS-C cameras
- 525mm equivalent focal length (35mm equivalent)
- Lightweight at 625g
- XD Linear Motor for fast autofocus
- Weather-sealed construction
- More affordable price point
Sony FE 70-300mm f/4.5-5.6 G OSS:
- Full-frame compatible lens
- 300mm maximum focal length
- Heavier at 854g
- Linear focus motor
- Includes focus limiter switch
- Better aperture at telephoto end (f/5.6 vs f/6.3)
Now, let’s dive into the details that really matter when you’re out in the field.
Sony Build Quality and Design
When I first picked up both lenses, the difference in build quality was immediately apparent. Both carry Sony’s prestigious G badge, which means they’re designed to deliver professional-grade performance, but they approach it differently.
Physical Dimensions and Weight
The Sony E 70-350mm is the clear winner when it comes to portability. At just 625g (22.1 oz), it’s significantly lighter than its full-frame counterpart. I’ve carried this lens for entire days during wildlife photography sessions, and my shoulders definitely thank me for choosing the lighter option. When extended to 350mm, it measures 190mm (7.48 inches), making it relatively compact for such a long reach.
On the other hand, the Sony FE 70-300mm tips the scales at 854g (30.2 oz) – that’s 229g (8.07 oz) heavier! When I’m hiking to remote locations or carrying multiple lenses, this weight difference becomes really noticeable. The FE 70-300mm extends to 210mm (8.27 inches) at 300mm, making it slightly longer when fully extended.
Weather Sealing and Durability
Both lenses claim to be dust and moisture resistant, but there’s a crucial difference I discovered during my testing. The E 70-350mm features a rubber gasket around the lens mount, providing better protection against dust and moisture. The FE 70-300mm, despite its higher price point, lacks this rubber gasket, which surprised me.
I’ve shot with both lenses in light rain and dusty conditions, and while both performed well, I feel more confident with the E 70-350mm’s sealing when the weather turns nasty. This is something to consider if you frequently shoot in challenging environments.
Control Layout and Features
This is where the FE 70-300mm shows its more premium nature. It includes a focus range limiter switch that allows you to limit focusing to between infinity and 3 meters. I discovered this feature is incredibly useful when shooting through fences at motorsport events or through glass at zoos – the lens won’t focus on the obstacles and instead jumps straight to your subject.
Unfortunately, Sony decided to exclude this focus limiter on the E 70-350mm, which I find disappointing. Both lenses do include an autofocus/manual focus switch, optical steadyshot on/off switch, and a zoom lock that prevents the lens from extending when at 70mm.
Lens Hoods and Filter Threads
The E 70-350mm comes with the ALC-SH160 bayonet-style lens hood and features a 67mm filter thread. The FE 70-300mm includes the larger ALC-SH144 hood and has a 72mm filter thread. Both hoods secure firmly with a twist-lock mechanism, so you won’t have to worry about them falling off during use.
I appreciate that both lenses include proper lens hoods – they’re essential for preventing flare and protecting the front element. The smaller filter thread on the E 70-350mm is a bonus if you already have 67mm filters from other lenses.
Optical Performance
Now let’s talk about what really matters – image quality. I’ve put both lenses through rigorous testing in various conditions, and the results might surprise you.
Sharpness Comparison
When I first started testing these lenses, I expected the more expensive FE 70-300mm to be significantly sharper. However, my real-world tests revealed that the difference is minimal and highly dependent on shooting conditions.
At maximum aperture and focal length (350mm f/6.3 vs 300mm f/5.6), I found that the FE 70-300mm has a slight edge in sharpness, but the difference is so small that you’d only notice it when pixel-peeping at 100%. When I stopped both lenses down by 1/3 stop (to f/7.1 on the E 70-350mm and f/6.3 on the FE 70-300mm), the sharpness difference became virtually nonexistent.
What impressed me most about the E 70-350mm is how well it maintains sharpness throughout its zoom range. From 70mm to 350mm, the image quality remains remarkably consistent, which isn’t always the case with super-telephoto zoom lenses.
Aperture and Low-Light Performance
The FE 70-300mm has a clear advantage when it comes to aperture. It maintains f/5.6 at 300mm, while the E 70-350mm drops to f/6.3 at 350mm. That one-stop difference might not seem like much, but I noticed it when shooting in low-light conditions or when trying to maintain faster shutter speeds for action photography.
Here’s how the apertures break down:
Sony E 70-350mm:
- 70-82mm: f/4.5
- 83-113mm: f/5
- 114-199mm: f/5.6
- 200-350mm: f/6.3
Sony FE 70-300mm:
- 70-82mm: f/4.5
- 83-153mm: f/5
- 154-300mm: f/5.6
The FE 70-300mm maintains a wider aperture for longer, which gives it an advantage in low-light situations and when trying to achieve shallower depth of field.
Bokeh and Background Rendering
Both lenses produce beautiful bokeh, but there are subtle differences. The FE 70-300mm features 9 aperture blades compared to the E 70-350mm’s 7 blades. This difference becomes apparent when shooting portraits or subjects with busy backgrounds – the FE 70-300mm produces slightly smoother, more rounded bokeh highlights.
However, I found that the E 70-350mm’s longer reach (350mm vs 300mm) often results in better background compression, which can make your subject stand out more dramatically. It’s a trade-off between aperture and focal length that you’ll need to consider based on your shooting style.
Chromatic Aberration and Distortion
Both lenses handle chromatic aberration well, but I noticed that the E 70-350mm shows slightly more purple fringing in high-contrast situations, particularly at the longer end of its zoom range. This is easily correctable in post-processing, but it’s worth noting.
Distortion is well-controlled on both lenses, with slight barrel distortion at the wide end and minimal pincushion distortion at the telephoto end. Nothing that would be problematic for real-world shooting.
Autofocus Performance
Autofocus performance can make or break a telephoto lens, especially when shooting fast-moving subjects. I’ve tested both lenses extensively with various Sony camera bodies, and here’s what I found.
Autofocus Speed and Accuracy
The E 70-350mm features Sony’s advanced XD Linear Motor technology, which is typically found in higher-end lenses. This gives it a slight edge in autofocus speed, particularly when shooting with newer Sony cameras that can take full advantage of this technology.
I conducted a series of autofocus tests using my dog Frank as a moving subject, and the results were interesting:
Sony E 70-350mm:
- Shots taken: 102
- Out of focus: 12 (12%)
- Slightly soft focus: 38 (37%)
- Critically sharp focus: 52 (51%)
- Keeper rate: 88% (including slightly soft)
Sony FE 70-300mm:
- Shots taken: 83
- Out of focus: 9 (11%)
- Slightly soft focus: 28 (34%)
- Critically sharp focus: 46 (55%)
- Keeper rate: 89% (including slightly soft)
The keeper rates are nearly identical, but I noticed that the E 70-350mm felt slightly more responsive and decisive when acquiring focus, particularly with newer Sony cameras.
Continuous Autofocus and Tracking
Both lenses perform well with continuous autofocus, but the E 70-350mm’s XD Linear Motor gives it an advantage when tracking fast-moving subjects. I found that it maintained focus slightly better when shooting birds in flight or fast-moving sports.
The FE 70-300mm, while slightly slower to acquire focus, proved to be very reliable once it locked onto a subject. The focus limiter switch (which the E 70-350mm lacks) can be a real advantage in certain situations, allowing you to prevent the lens from hunting for focus in the wrong distance range.
Low-Light Autofocus
In low-light conditions, both lenses performed admirably, but the FE 70-300mm’s wider aperture at the telephoto end gave it a slight advantage. The extra light gathering ability helps the autofocus system work more effectively in dim conditions.
I tested both lenses at dusk and in indoor sports venues, and while both worked well, the FE 70-300mm acquired focus slightly more quickly in challenging lighting situations.
Image Stabilization
Image stabilization is crucial for telephoto lenses, especially when shooting handheld. Both lenses feature Optical SteadyShot (OSS), but there are some differences in performance.
Stabilization Effectiveness
Both lenses provide excellent stabilization, but I found that the FE 70-300mm’s stabilization felt slightly more effective, particularly at the longer end of its zoom range. This might be due to its more advanced optical design or simply because it’s optimized for full-frame sensors.
I was able to get sharp handheld shots at 1/60th of a second at 300mm with the FE 70-300mm, while I needed to keep shutter speeds around 1/80th or faster with the E 70-350mm at 350mm to achieve similar results.
Stabilization Modes
Unfortunately, neither lens offers multiple stabilization modes like some of Sony’s higher-end telephoto lenses. Both simply have an on/off switch for the stabilization system. While this is sufficient for most situations, I would have appreciated having different modes for static subjects versus panning shots.

Real-World Performance
Specifications and test charts are one thing, but how do these lenses perform in real-world shooting situations? Let me share my experiences using both lenses for various types of photography.
Wildlife Photography
This is where both lenses truly shine, but in different ways. The E 70-350mm’s extra reach (525mm equivalent on APS-C) is fantastic for getting close to distant subjects without disturbing them. I’ve captured some amazing bird shots with this lens that simply wouldn’t have been possible with the FE 70-300mm.
However, the FE 70-300mm’s wider aperture and slightly better image quality give it an advantage when shooting in less-than-ideal lighting conditions. During early morning or late evening wildlife sessions, I found myself reaching for the FE 70-300mm more often.
Sports Photography
For sports photography, both lenses perform well, but the FE 70-300mm’s focus limiter switch and slightly faster aperture give it the edge. When shooting sports like soccer or football, where subjects move quickly and lighting can be challenging, the FE 70-300mm proved to be more reliable.
That said, the E 70-350mm’s lighter weight makes it easier to handhold for extended periods, which can be a real advantage during long sporting events.
Landscape Photography
For landscape photography, both lenses work well, but the FE 70-300mm’s full-frame compatibility gives it an advantage if you’re using a full-frame Sony camera. The ability to capture wider scenes with better dynamic range is significant for landscape work.
However, if you’re shooting with an APS-C camera, the E 70-350mm is perfectly capable of producing stunning landscape images, and its lighter weight makes it more pleasant to carry on long hikes.
Portrait Photography
Neither lens is ideal for portrait photography due to their relatively slow maximum apertures, but both can produce pleasing results when used correctly. The FE 70-300mm’s wider aperture and 9-blade diaphragm give it an advantage for background blur, but the E 70-350mm’s longer focal length can provide better subject separation.
I’ve used both lenses for environmental portraits, and while they’re not my first choice for this type of photography, they can produce nice results when you need the versatility of a zoom.
Sony Camera Compatibility
One of the most important considerations when choosing between these lenses is camera compatibility. The choice becomes much clearer once you consider which camera body you’re using.
APS-C Cameras (a6000 series, a6100, a6400, a6600, a6700)
If you’re shooting with an APS-C Sony camera, the E 70-350mm is the obvious choice. It’s designed specifically for these cameras, providing a perfect balance of size, weight, and performance. The 525mm equivalent focal length is fantastic for wildlife and sports photography.
I’ve used the E 70-350mm extensively with my a6400 and a6700, and the combination is superb. The lens balances perfectly on these smaller bodies, and the autofocus performance is excellent.
Full-Frame Cameras (a7 series, a9 series, a1)
For full-frame Sony cameras, the FE 70-300mm is the native choice, providing full sensor coverage and optimal performance. However, you can use the E 70-350mm on full-frame cameras in crop mode, which gives you an effective 525mm focal length.
I’ve tested both lenses on my a7R IV, and while the FE 70-300mm provides better image quality across the full frame, the E 70-350mm in crop mode offers incredible reach in a compact package. This makes it a great option when you need maximum telephoto reach without carrying a massive lens.
Price and Value
Price is always an important consideration, and there’s a significant difference between these two lenses:
- Sony E 70-350mm f/4.5-6.3 G OSS: Approximately $998 USD
- Sony FE 70-300mm f/4.5-5.6 G OSS: Approximately $1,273 USD
That’s a difference of about $275, which is substantial. The question is whether the FE 70-300mm’s advantages justify the higher price.
For APS-C camera users, the E 70-350mm offers exceptional value. It provides excellent performance, great build quality, and fantastic reach at a reasonable price point.
For full-frame users, the FE 70-300mm’s higher price is justified by its full-frame compatibility, better aperture, and additional features like the focus limiter.
Sample Images and Real-World Examples
I’ve captured thousands of images with both lenses, and I’d like to share some observations about their real-world performance.
Wildlife Examples
With the E 70-350mm, I’ve captured stunning bird images that showcase its impressive reach. The ability to frame small birds at 525mm equivalent is remarkable, and the image quality holds up well even at the extreme end of the zoom range.
The FE 70-300mm, while not offering as much reach, produces slightly cleaner images with better contrast, particularly in challenging lighting conditions. I’ve used it extensively for larger wildlife like deer and foxes, with excellent results.
Sports Examples
For sports photography, both lenses perform well, but I found the FE 70-300mm to be more reliable for fast-paced action. The focus limiter switch is particularly useful when shooting sports where there are obstacles between you and the action.
The E 70-350mm, while slightly slower to acquire focus in some situations, proved to be excellent for sports where you need the extra reach, like baseball or soccer.
Landscape Examples
Both lenses can produce beautiful landscape images, but the FE 70-300mm’s full-frame compatibility gives it an edge when used with full-frame cameras. The wider dynamic range and better low-light performance of full-frame sensors combined with this lens produce stunning results.
The E 70-350mm, when used on APS-C cameras, still produces excellent landscape images, particularly when you need that extra telephoto reach for compressed landscapes.
