This is the same lens as the Varo 90mm f1.0. It is quite unique in that the flange distance is long enough to achieve infinity focus on a mirrorless camera, and I believe that the image circle will cover or nearly cover MF. Optical quality is surprisingly good. It is quite sharp and the corners are decent. There is some CA which cleans up nicely, and some blooming around highlights, which actually is quite amenable to sharpening. Work against the light is surprisingly good. Vignetting too is well controlled, at least on full frame. I just got the lens and took it out for a stroll yesterday. Here are some images, processed to get the best out of them.
