What camera do you use?I know a lot of people like slr's. I have too many other hobbies right now to figure out the workings of an slr. I have a point and shoot....though it's a point and shoot with lots of bells and whistles, and I can get some special lenses, like extended optical zoom, better macro, filters, etc.... In my cameras, I like there to be a good macro mode, and a good optical zoom. I usually ignore digital zoom because I like to print my pictures and digital zoom tends to pixelate the printed picture.
If you want a point and shoot i would say get a Casio Exilim (any Model)
I took these yesterday with my Exilim. I'm on my third one- I love them so much I keep upgrading!
If you want a really cheap body, the Nikon D40 with a lens is cheaper than most higher end point and shootsI agree with people that point and shoot cameras will do fine, However... Dslr cameras offer so much more freedom, and much better results.
You can get a cheap body now, like the Canon Rebel series and a nicer(more expensive) lens.
For example, I have a rebel Xti body, with a beautiful 75-200 f. 2.4 lens. With a lens like this i can get wicked macro shots with very good sharpness.
