Sigma 105mm F2.8 DG DN MACRO | Art

Reviewers found it one of the sharpest lenses in Sigma's mirrorless range. Resolution is very high from f/2.8 at both macro and normal distances, with almost no distortion and very little lateral or longitudinal CA. Bokeh is smooth for a macro design, which makes it a credible 105mm portrait lens as well.

Autofocus is the weak point. It is fine for portraits and general use but noticeably slower than linear-motor rivals, and it can hunt at close focus distances. Testers also mention the absence of stabilisation compared with Sony's FE 90mm Macro G OSS, and that the lens is long and front-heavy once the hood is fitted.

Owners praise the image quality, the price, and the build of the aperture ring and switches. Many use it as a combined macro and portrait lens and say it replaced both on their kit list. The focus limiter is used often to tame hunting.

Complaints focus on AF speed and noise in macro work, the lack of OS for handheld close-ups on older bodies, and the size compared with older 90mm macros. A few users report that AF tracking of insects is unreliable and prefer manual focus at 1:1.
