Overview

The RO2-2 75 mm f/2 lens, tested on a Sony NEX-5 at f/2.8, shows decent center sharpness but soft edges, as noted by user SharkDD. Build quality is not explicitly discussed, but the lens appears compact for mirrorless use. It suits photographers who prioritize a fast normal-length prime for portraits or low-light, provided edge sharpness is not critical. The single user review suggests moderate usefulness (3.6/5).
