TTArtisan 50mm f2 Hands on Review -- $69 Full Frame Lens for Sony, Fuji, Nikon, M4/3 and Leica Cameras
The focus has a very smooth focused throw, the geared part of the ring is quite thin but since it's so smooth you can grip it pretty much wherever the aperture comes with clicks this time.
It will be a little soft compared to step down but way sharper than you would have thought for a lens costs just about $100!
It's a perfect lens which lets you set a zone from just above one meter to infinity, at f4, it's great for street photography with the added bonus of an f 1.4 aperture to achieve a little bit of separation as a bonus. And also let in more light combined with a very lovely close focus of only 20 centimeters. It's quite fun to use for spring trips with the big aperture.
