Roger Cicala from LensRentals.com has tested the new Sony FE 135mm F1.8 GM lens and said: “This is the sharpest lens we’ve tested. Period. (At last count, that’s out of 300+ lenses tested.)
Roger and his team tested 10 pre-release copies of the new Sony FE 135mm F1.8 G Master Lens and averaged out the results. The first test showed MTF curves higher than anything they had ever seen in a normal-range lens. (Lenses like 400mm f/2.8 super telephotos, are about this high. But those are super telephotos. And f/2.8.).
The MTF tests showed that it’s dramatically better in the center of the image than the Sigma 135mm F 1.8, especially at higher resolutions. It’s also sharper in the center half of the image even at f/1.8 than the Zeiss 135mm Batis is at f/2.8.
