This was split from it's mother topic because it can and should stand on its own.
Cameras for gun photos:
Most of the little point and shoot cameras are really good. Make sure it has a 'macro' feature, which shows as a flower symbol on the selector knob.
Don't be sold on huge mega-pixels, you'll never need all of them. You have to downsize photos anyway to get them on the web. My old Canon was a 3 or 4 megapixel, and it was fine for all my gun photography. Canon, Panasonic, Sony, Nikon are all good.
You don't need lots of bells and whistles, but most cameras now come with a dizzying array of controls. But some of these will be essential to learn in order to get good photos in the workshop. Macro, center focus, timer, and F-stop are all good to learn about to get your best photo quality. A tripod may be your best friend for crisp photos in a workshop setting.
I have an SLR Nikon now, and it certainly takes good pictures. But it's a lot of money, AND it's bulky. If I travel to a museum or show, it's a pain because it's heavy and awkward. One day, after the economy bounces back, I'll get a small point and shoot.
