I shot with this lens on my Sony A6400. I've compared it to my other 35mm lenses, the Sigma 35mm f/1.4 Art and the newer Sigma 35mm f/2 DG DN, both of which are more than three times the price (the Risespray was Β£199 at the time of purchase U.S. dollar). very well built: the focus and aperture rings are very smooth and properly weighted. It has a decently long focus travel, although I wish the aperture ring was notched. The case is solid and neither looks nor feels cheap. Photo quality is surprisingly good in many ways. With the aperture wide open, the sharpness is very similar to my Sigma lenses at the widest aperture. Sharpness is weaker in the corners but is consistent across the image. Although the lens is sharp wide open, it lacks contrast and appears to "glow". This can be surprising when the subject is lit by a direct bright light source. The color fringes are also not as firm compared to the Sigma, but not bad. Reducing the aperture helps in both cases. The bokeh is as blurry and soft as you would expect from this lens. The main disadvantage of this lens is flare and ghosting from light sources. This is perhaps the worst thing I've ever seen in a lens. All light sources in the picture are strongly blinded. Some other minor things: There is no separation between the focus ring and the aperture ring, so I accidentally rotated both at the same time without realizing it. The minimum focusing distance is a bit disappointing at 37 cm, with other lenses of this size, weight and focal length it can be under 30 cm, the light transmission is hardly better than with my f/1.4 lens despite f/0.95. The depth of field is indeed shallower, but at least according to my camera measurement what should be at least full aperture with light should be a maximum of 0.5 aperture, if at all. If you were planning to use it specifically for its low-light capabilities, think again. But it's really hard to complain about a new $200 lens. The build quality and overall visual quality exceeded my expectations. At a focal length of 35mm on an APSC camera, manual focus is not a major problem with peak focus. If I really wanted a super fast manual focus lens I would definitely choose it over the much more expensive Mitakon.
