My camera is a Canon Powershot A640 My wife has a Canon Powershot A610. Yes they are old, and both cameras have been used for MEW photos. Neither is SLR, and cost £155 (s/h) and £165 (new). Yet both have a facility which I certainly find very useful – an optical viewfinder, which means that for those awkward shots, I can hold the camera to my head and thus get an additional degree of steadying (at my age, I'm not as steady as I used to be). Neither of the cameras mentioned by Neil appear to have this facility. I do have a tripod which I use wherever possible for workshop photos, but occasionally I can't get it into a suitable position, hence have to resort to manual handling.
Although they are not SLR's, they do have a large number of facilities – macro, manual focusing, auto, TV, AV and a means of focusing on a particular place or spot, and then moving the picture without losing the focus. Plus a host of other facilities which I've never used. So although they cannot compete with a SLR, they can produce photos good enough for the magazine.
The biggest problem I have is that of lighting. Both cameras have built in flash which can be switched off, but there is no facility for external flash. Which does make for problems. Essentially I end up taking large numbers of experimental photos and choosing whichever one seems best.
