What kind of camera(s) are y'all using?
I've got a Kodak Playsport. It's a video camera that can take stills. Unfortunately, it has a focal length of about 4 1/2', so if I take a shot of a fly "in focus", you won't be able to make out any details.
I also have a Nikon D40, but the lens is broken. For the kind of money that I would flip out to replace the lens, I can buy a smaller camera new.
I use a Cannon Powershot XS100 is. It's about 6-8 years old and works great. It has a Macro feature that lets you focus in on very small items like insects and flies. It also has a 10X optical zoom and a total of 40X digital. One of the best features is that it uses 2 AA batteries. I try to always carry it in my pocket and use it as much as possible.
Allen, I use a canon powershot S5is that has a macro and super macro mode that lets you focus within just a few inches of your subject. Also picasa3 software which is a free google product will let you crop pictures and make all kinds of adjustments for improved picture quality. I always shoot against a blue background which helps to keep from "blinding" the camera. Here's a sample.
