Its reliance on in-body image stabilization may look like a disadvantage, but with sensor-based stabilization becoming better with newer camera bodies this may well turn out to be a benefit. It produces extremely sharp images devoid of colour aberrations and has a very good feature set – including a de-clickable aperture ring and the options to use teleconverters and get the lens-mount swapped (at a cost). Its performance is excellent, out-resolving the Sony FE 90mm f2.8 Macro G OSS at f2.8 in almost every test especially at close and closest distances. The 105mm f2.8 DG DN Macro Art is the first macro lens for Sigma’s DN-series of lenses designed specifically for mirrorless cameras, currently available in Sony E-mount and Leica L-mount. Let’s put this into perspective and have a closer look at how the Sony compares to the more recent Sigma 105mm f2.8 DG DN Macro Art.Ĭompared to Sigma 105mm f2.8 DG DN Macro Art And if you develop RAW files from this lens with Adobe’s RAW-converter don’t forget to manually activate distortion compensation in the software as Adobe does not recognize the camera setting. Flare, (veiling) glare, and ghosting could be better suppressed and there is visible focus-breathing which might be distracting when shooting videos. Bokeh is pretty soft although Bokeh balls are not perfectly circular at f2.8 when focused close. Its autofocus is quiet, reliable, and not too slow. It shows only mild colour aberrations and has practically no field-curvature which is important when reproducing flat objects. How’s it perform? The lens is very sharp across the full-frame sensor but benefits from stopping down to f4.0 once you focus closer. This all comes at a price which does not seem unreasonable for a light tele-photo macro lens from a camera manufacturer. Only a de-clickable aperture ring is missing and you cannot use teleconverters. It has a pretty complete feature-set with thorough weather sealing, optical image stabilization, focus limiter, focus-lock button, and an interesting dual mechanism for manual focus: you can switch between fast linear focus gearing and slow variable gearing for precise manual focus. The FE 90mm f2.8 Macro G OSS was the first mirrorless design for macro work on Sony’s E-mount cameras when it came out in 2015.
