This little Chinon 50mm f/1.9 Auto is a lightweight lens but is built pretty cheaply. Also Optically it is simply not too exciting. Chinon usually produces some decent lenses, but this is not one of them.

I feel bad for the people who bought their nice new Ricoh camera with this Ricoh Riconar 55mm f/2.2 kitted with it. This lens is very poor. However if you want some strange and artsy spherical aberration, this lens is interesting to play with.
