Meanwhile the battery and charger for the camera I got last week arrived when I was out, and it looks like I now own a fully operational Sony NEX-5 for about £40 including the camera, charger, battery and memory card. I shall have to take it out and play with it, it's a lot more advanced than my other cameras but I think I prefer an SLR. Where it might do well is in the same role as the Canon I got, for testing weird lenses, since the body depth is teeny. I could REALLY wish I'd picked this up before I'd bought the Canon and so far eight or nine adapters for other lenses...
