I left the old Canon S70 with them for a while and returned to find it repaired sufficiently for the lens to stay out all by itself. "The parts are very worn", I was told. So the repair won't last all that long, but at least the camera is now functioning reasonably normally for a modest outlay of £20.
The shop has masses of 'Real Cameras'. But they offered only a fiver for my old
EOS 300, so I'll hang onto that for the time being. They do seem to be enthusiasts, and may well be able to help for minor repairs, as in the case of my S70.
