I'm currently using an Fuji Finepix A210, and while for the most part I'm satisfied with it, I need something better. While it takes fantastic general photos of herps and tarantulas, it doesnt do well with small fine details. Examples would be trying to focus in on reptile eyes, the tiny claws on the end of a tarantulas foot, insects, small spiders etc. While I can get a photo of a small (under 1/2 inch) spider to turn out, it lacks details and looks like crap compared to my snake photos.
I have tried everything to get them to turn out, all different lighting, the specimens are still, and nothing works. So what type of camera should I get that takes better photos of the little things? Maybe an SLR but what type of lense do I need? Any and all comments and ideas welcome!!
