Tamron 90mm f2.8 Di III VXD Macro
Tamron 90mm F/2.8 Di III VXD 1:1 Macro for Sony E Mount Full Frame/APS-C Mirrorless Cameras
Pros
- Lighter and more compact design
- Closer minimum focus distance
- Excellent sharpness across frame
- Faster VXD autofocus motor
- Lower price point
Cons
- No aperture ring on lens
- No focus limiter switch
The Tamron 90mm f2.8 Di III VXD Macro represents the company’s latest approach to macro photography, bringing their renowned VXD motor technology to a focal length that hits a sweet spot for versatility. Released in late 2024, this lens has quickly gained attention for delivering flagship-level performance at a more accessible price point than competitors.
I spent three weeks shooting exclusively with this lens for product photography and casual macro work. The first thing you notice is how light it feels in hand compared to the Sigma. At 630g, it is significantly easier to carry on long shoots or when hiking to find interesting macro subjects. The balance on my Sony A7 IV felt natural, and I never experienced fatigue during extended handheld sessions.
The VXD motor lives up to its reputation. I tracked crawling insects and fluttering butterflies with surprising accuracy. The speed surprised me for a macro lens, which traditionally prioritize precision over velocity. In low light situations, the autofocus hunted less than I expected, locking onto subjects reliably even when shooting at f2.8.
Image quality is where this lens truly shines. The flat-field performance means your subjects stay sharp from edge to edge, crucial when photographing documents or products where corner softness would be unacceptable. The BBAR-G2 coating effectively controlled flare when shooting into light sources, and chromatic aberration was virtually non-existent in my test shots.
The 0.23m minimum focus distance lets you get incredibly close to your subjects. I found this particularly useful for photographing small flowers where getting physically closer helped isolate details. The moisture-resistant construction gave me confidence shooting after light rain, though I would not submerge it.
What keeps this from being perfect is the lack of an aperture ring. You must control aperture through your camera body, which some photographers find less intuitive. There is also no focus limiter switch, meaning the lens will hunt through its full range when searching for focus. These are minor inconveniences rather than deal-breakers.
Sigma 105mm f2.8 DG DN Macro Art
Pros
- Exceptional build quality
- Physical aperture ring with clicks
- Focus limiter switch for faster AF
- Longer working distance
- Better bokeh rendering
Cons
- Heavier than Tamron
- More expensive
- Slower AF in some situations
The Sigma 105mm f2.8 DG DN Macro Art has been the benchmark for third-party macro lenses since its release in 2020. As part of Sigma’s prestigious Art line, it promises optical excellence and professional-grade build quality. After four years on the market, it remains a top choice for serious macro photographers.
Our team used this lens extensively for portrait work and insect photography over a month-long testing period. The first impression is one of substance. This lens feels built to last a lifetime, with a metal construction that inspires confidence. The 85g weight difference compared to the Tamron is noticeable, especially during all-day shoots, but the trade-off is a sense of durability that cheaper lenses cannot match.
The aperture ring is a feature I grew to love. Being able to quickly change aperture without diving into camera menus speeds up workflow significantly. The clicked and de-clicked options cover both stills and video work. The focus limiter switch proved invaluable when shooting insects, preventing the lens from hunting through its full range when I knew my subject would be at macro distances.
Optically, this lens is stunning. The 9-blade aperture produces some of the smoothest bokeh I have seen from a macro lens. Portraits taken at f2.8 have that dreamy, three-dimensional quality that separates professional work from amateur attempts. Sharpness is exceptional, with only minimal softening at the extreme corners when wide open.
The extra 15mm of focal length might not sound significant, but it translates to meaningful working distance. When photographing skittish insects, those extra centimeters matter. You can achieve 1:1 magnification while standing further back, reducing the chance of casting shadows on your subject or startling it. This also makes the lens more flattering for portraits, compressing facial features in a more pleasing way than the 90mm.
The hypersonic motor is generally smooth and accurate, though I found it slightly slower than the Tamron’s VXD system in some scenarios. For macro work where you are often using manual focus anyway, this is rarely an issue. The lens can hunt when shooting jewelry or highly reflective surfaces, so manual focus is sometimes necessary.
Tamron 90mm vs Sigma 105mm: Head-to-Head Comparison
Optical Performance and Sharpness
Both lenses deliver exceptional sharpness that will satisfy even demanding professionals. Forum discussions consistently mention Dustin Abbott’s testing, which showed the Tamron as slightly sharper at macro distances, while the Sigma maintains better uniformity across the frame for portrait work.
In my real-world testing, the differences are subtle. The Tamron produces marginally more detail when shooting flat subjects like documents or stamps. The Sigma handles three-dimensional subjects with better edge-to-edge consistency. For most photographers, either lens will exceed their sharpness requirements.
Autofocus Performance
The Tamron’s VXD motor wins for pure speed. It tracks moving subjects more confidently and acquires focus faster in general photography scenarios. The Sigma’s hypersonic motor feels slightly more deliberate, prioritizing accuracy over velocity.
However, the Sigma’s focus limiter switch gives it a practical advantage for macro work. By restricting the focus range, you eliminate hunting through the full range when your subject is already at macro distances. This feature alone makes the Sigma more efficient for dedicated macro photographers.
Build Quality and Weather Sealing
Both lenses feature weather sealing, though the Sigma’s construction feels more robust. The metal body of the Sigma Art line inspires more confidence for professional use, while the Tamron’s lighter polycarbonate construction prioritizes portability.
Neither lens has failed in wet conditions during my testing, but the Sigma’s heft suggests it would survive more abuse over years of professional use. For hobbyists or those who baby their gear, this difference may not matter.
Size and Weight
The Tamron is the clear winner here. At 630g versus the Sigma’s 715g, it makes a noticeable difference during long shooting sessions. The Tamron also has a slightly smaller footprint, making it easier to pack in already-full camera bags.
If you value traveling light or shoot handheld for extended periods, the Tamron’s weight advantage becomes significant. The Sigma’s extra mass does contribute to better balance on larger camera bodies, so your choice of camera body should factor into this decision.
Working Distance
The Sigma’s 105mm focal length provides about 7 centimeters more working distance at 1:1 magnification compared to the Tamron’s 90mm. This might not sound like much, but when photographing live insects or subjects that cast shadows easily, that extra space is valuable.
The Tamron compensates with a closer minimum focus distance of 0.23m versus the Sigma’s 0.30m. This means you can get physically closer to subjects when needed, though this is sometimes impractical for lighting and shadow reasons.
Bokeh and Aperture Control
The Sigma produces more pleasing bokeh thanks to its 9-blade aperture design versus the Tamron’s 7 blades. The circular bokeh balls remain rounder when stopped down, and the transition zones are smoother. For portrait photographers who also shoot macro, this gives the Sigma an advantage.
The physical aperture ring on the Sigma is a workflow advantage that the Tamron cannot match. Being able to see and feel your aperture setting without looking at the camera display speeds up shooting and provides tactile feedback that many photographers prefer.
Which Lens for Which Photography?
For Insect and Wildlife Macro: Sigma 105mm
The extra working distance makes the Sigma the better choice for photographing live insects, spiders, and other skittish subjects. You can achieve true 1:1 magnification while maintaining enough distance to avoid disturbing your subject or casting shadows. The focus limiter switch also speeds up acquisition when shooting active creatures.
For Product Photography: Tamron 90mm
The closer minimum focus distance and slightly sharper flat-field performance give the Tamron an edge for product work. You can get closer to small items for detail shots, and the lighter weight makes it easier to maneuver in tight studio spaces. The lower price also matters when building a product photography kit.
For Portrait Photography: Sigma 105mm
The longer focal length is more flattering for faces, providing better compression and separation from backgrounds. The superior bokeh rendering and physical aperture ring also make the Sigma more enjoyable for portrait sessions. If you shoot people as often as macro subjects, the Sigma is the better dual-purpose lens.
For Flower and Plant Photography: Tie
Both lenses excel here. The Tamron’s closer focus lets you capture more detail in small blooms, while the Sigma’s working distance helps with lighting. Choose based on whether you prefer to work closer to your subjects or maintain more distance.
