I've been given a Ricoh GR Digital II to play with — sort of a long term loan really. Lovely little camera. In the past I've messed about with Olympus film and digital, and Nikon compacts and SLRs with other manufacturer's lenses using converter rings and reverse mounts (for super macro effects).
I'd like to try something similar, but I can't see any evidence that others have tried this online, and can't find any converter rings or etc.
Any thoughts? The GR II is so good in terms of features and the 10MP ccd etc, I'd love to hack it a bit in terms of optics.
