SonyAlphaRumors reported an interesting rumor: Sigma will soon launch it’s first Full Frame autofocus lenses for mirrorless system. The first lens will be a 35mm f/1.4 lens and the second will likely be a zoom lens. SAR reports:
Now of course we know there are only two Full Frame Mirrorless systems yet (Sony and Leica). But I guess these lenses will work on the smaller sensor systems too (Fuji, MFT, Canon). An interesting hypothesis is that maybe these lenses will work on the Fuji GFX system. After all it seems that most FF lenses do work fine on the GFX system too.
