They were lying in a cupboard - Pentax K mount and Minolta AF lenses, so why not try and use them? So I bought a couple of adapters. The manual lenses from the Pentax work without a problem - once all the appropriate settings have been made on the G3. The Minolta lenses being auto, are a different matter - lots of lens jitter. Concluded that the answer might be to set up the lenses on the old Minolta 9xi, choose an aperture then switch the lens to manual before putting it on to the G3. That seems to work by setting the same aperture on the G3, but it's not exactly convenient. (I'm sure someone will tell me I should step down or up) Is there any other way? I guess probably not, if I really wanted to get use out of the Minolta lenses I should have bought a Sony. No big deal, there's plenty to be done with the camera and it's kit lens, just liked the idea of the challenge, to see if I could beat the machines into submission.
