I had one of these adapters (m42 to F). It was so incredibly bad it wasn't even funny. It is, however, a cheap way of getting a soft focus lens.
I saw warnings about the IQ degradation, especially in the M42 adapters or ones with the element, which made me weary. However, it's not a huge investment to try.
I might have to wait until I have something more to buy, as buying from B&H is not always economical when shipping to Canada :P
