Photozone posted the full Sony 90mm FE macro lens review and there is good news folks:
Sony has come a long way since they entered the system market several years ago. During this journey We became a bit skeptical because of various quality issues. However, it seems as if they are finally getting their act together now. Unlike with their APS-C format lenses we have yet to experience significant centering issues with Sony’s full format E-mount lenses.
The Sony FE 90mm f/2.8 G OSS macro is a good example how things improved. In terms of optical quality it is easily playing on the same levels as its DSLR counterparts. In terms of sharpness the Sony lens has probably surpassed them.
