Canon 105mm f/2.8 EX DG OS HSM Macro 105mm

The Sigma 105mm f/2.8 EX DG OS HSM Macro for Canon EF mount delivers beautiful bokeh and a bright f/2.8 aperture, but its optical sharpness and macro performance are surprisingly weak for a lens with "Macro" in the name. Portrait shooters who prioritize background blur over sharpness might find value here, but most people should look at more modern alternatives.

Let's talk about what this lens actually does well. The f/2.8 aperture is a standout feature here, putting it in the 83rd percentile. In practice, that means you can shoot in lower light than most macro lenses and get that creamy background blur for portraits. The bokeh itself is one of the best on the market for this category, ranking in the 81st percentile. Out-of-focus areas render smoothly without that busy, nervous look you get from cheaper glass. For portrait work, this is the lens's saving grace.

But the sharpness story is where things fall apart. Optical quality sits at a disappointing 22nd percentile, which means this lens lags behind most of its peers in raw resolving power. Macro performance is even worse at the 14th percentile, one of the worst we've seen for a dedicated macro lens. If you're shooting insects or product details and need every hair and texture to pop, this lens will leave you frustrated. Autofocus is middle of the pack at the 54th percentile, so it's not terrible, but it's not going to impress anyone either. And with no stabilization, you'll need steady hands or a tripod for any serious macro work.

Stacked against the competition, the Sigma 105mm f/2.8 EX DG OS HSM Macro struggles to justify its price. The Tamron Di III AFA074S700 is a more modern design with better optical performance and faster autofocus. If you're open to a zoom, the Sigma Contemporary 28-70mm f/2.8 DG DN gives you way more versatility with similar aperture brightness and sharper results across the frame. Even the Nikon NIKKOR Z 17-28mm f/2.8, while a completely different focal range, shows what modern lens design can deliver in terms of sharpness and build quality.

The Panasonic Leica DG Vario-Elmarit H-ES12035 and Sony E PZ 16-50mm f/3.5-5.6 OSS are different beasts entirely, but they highlight how far lens tech has come. The Sony in particular offers stabilization and better versatility at a fraction of the price. The Sigma 105mm's only real advantage is that f/2.8 aperture and the bokeh quality, which are genuinely good. But for most shooters, trading sharpness and modern features for bokeh alone is a tough sell.

At $825, this lens is in a weird spot. You're paying mid-range money for a lens that delivers below-average optical and macro performance. The bright aperture and nice bokeh are the only things keeping it from being a total pass. For portrait shooters who already own a Canon DSLR and want a 105mm prime with character, it might make sense. But there are better options. The Tamron Di III and Sigma Contemporary 28-70mm both offer more modern optical designs and better all-around performance. If macro is your main priority, you can find sharper options for less money. This lens only makes sense if you specifically need the f/2.8 aperture and 105mm focal length on an EF mount and you're willing to trade sharpness for bokeh.

The Canon 105mm f/2.8 EX DG OS HSM Macro is a bit of an odd duck. The name is a mouthful, and right away you'll notice something weird: it's actually a Sigma lens, despite the "Canon International" branding you see on some retailer listings. This is Sigma's older EX DG OS HSM Macro, just sold for Canon EF mount. It's a 105mm prime with a bright f/2.8 aperture, and it's been a workhorse for DSLR shooters who want a telephoto macro lens that can pull double duty for portraits. At around $825, it sits in that mid-range territory where you're expecting solid performance without breaking into pro-exotic territory.

On paper, the specs tell an interesting story. The f/2.8 aperture ranks in the 83rd percentile for this category, which means it's brighter than most macro lenses out there. Bokeh quality is also well above average at the 81st percentile. But the rest of the numbers paint a picture of a lens that's showing its age. Optical quality lands in the bottom quarter of the pack, and macro performance specifically is a disappointing 14th percentile. For a lens with "Macro" right in the name, that's a tough pill to swallow.

This lens is best suited for portrait photographers on a budget who want that classic 105mm compression and decent background separation. It scores a respectable 57.1 out of 100 for portraits. But if you're a landscape shooter or someone who needs tack-sharp macro detail, you'll want to keep scrolling. The 13.9 out of 100 landscape score tells you everything you need to know there.

Landscape photographers should absolutely skip this lens, the 13.9 out of 100 score is a dealbreaker. Video shooters will also be disappointed by the 35.2 cinema score and lack of stabilization. If macro detail work is your main gig, look elsewhere, the 14th percentile macro performance means you won't get the sharpness you need for insects, flowers, or product photography. Anyone who values sharpness over bokeh should check out the Tamron Di III or Sigma Contemporary 28-70mm instead. And if you're on a mirrorless system, this EF-mount lens requires an adapter, which adds cost and bulk for already mediocre performance.

This is a lens for a very specific person. If you're a Canon DSLR portrait shooter who values bokeh above all else and you don't mind soft images, the Sigma 105mm f/2.8 EX DG OS HSM Macro might scratch an itch. The f/2.8 aperture and smooth background blur are legitimately good, and the 105mm focal length is a classic for a reason. But calling this a macro lens feels misleading when its macro performance is one of the worst we've seen.

For most people, the answer is no. The optical quality is disappointing, the build is below average, and there's no stabilization to help with handheld shooting. You can get sharper lenses with better macro performance for less money. Unless you're specifically chasing that dreamy bokeh look on an EF mount and you're willing to accept soft images, skip this one. There are just too many better options in 2025.
