About This LensThe TTArtisan Neo AF 50mm f/1.8 is an extremely compact and lightweight prime autofocus lens designed for full-frame mirrorless cameras. Priced at just $89, it is an attractive option for photographers looking for an inexpensive everyday lens, though test results show softness and purple fringing at f/1.8, with sharpness improving noticeably by f/2.8.
