Converting lenses

In case anyone wants to use their lenses on a different camera body, I've just converted a Leica R bellows to Canon mount using an adapter bayonet from www.leitax.com. The adapter is beautifully made, very easy to fit and works perfectly. Service was excellent too. They offer a range of adapters so if you have old but good lenses lying around.... of course for underwater use both aperture and focus rings might be needed too!
