My first Ricoh camera was the GRD, the first digital GR camera. I bought the GW-1 21mm wide adapter lens and grew to love using it often. I eventually upgraded and passed the GR and GW-1 to my daughter who unfortunately dented the front ring and scratched the glass (she was very young).
Eventually I picked up a GRD3 and missed the wide angle 21mm so bought an adapter ring to step down the GH-2 adapter tube filter thread to the GW-1 37mm. It worked well, with a slight vignette which I also grew to love.
Today I have the GR and looked longingly at the GW-1 again. Could this lens from 2005 be a good match to the dramatically different optics designed for an APS-C sensor? I expected to see a lot of vignetting at least but it turned out surprisingly well.

Despite the scratches the front element of the GW-1 has I don't see much if any effect in the shots, and the denting and scratches merely add to the charm now.
I don't know if the GW-1 is giving me a true 21mm view, I have no way of testing this other than buying the correct lens and comparing shots, but I'm not going to drop £200 to find out. I can probably set up a test area with a tripod and marked up target, measure distances etc and do some math, I'll look into it. But do I care? It's definitely substantially wider, so no.
It's also fun, knowing this is a kind of a hack, using a lens that's nearly 10 years old.
