I have a couple of the Olympus models that we got a few years ago. Very dependable. Here are some things to consider
- Although the Olympus cameras we have use their propietary lithium battery packs, they also use AA's and that all we have been using in them. I can buy them in bulk and it is an inexpensive alternative.
- Get as much resolution as you can. It will help when you compose, crop and edit the picture the second time on your computer prior to printing. It is important to get as much detail as possible, if it ain't there when you take it, you can't get it later.
- Check out the different types of media that the different brands use. We like the SmartMedia cards, but there are other good solutions.
- Our larger camera is a 2.8 megapixel model (high quality for it's day) but it has a threaded lens housing that allows us to use a protective filter. Our smaller ones are the clamshell designs and offer adequate protection, especially in pack.
- Optical as well as mechanical zooms with macro features make it very handy to get in very close to read serial numbers and other stuff in out of the way places if you photograph them. It is often easier to get the camera in the space to see them that are impractical to get your head.
Hope these considerations are of some help.
