I have been out photography for sometime and want to finally grab a digital slr. I have some great lenses.....SMC-F300mm, SMC-FA80-200 f2.8, an old smc-m 400mm f5.6 that I want to keep using. Along with an old flash or two. Most of my shooting would be hiking, nature, and sports related. My last body was a zx-5n. Any suggestion on getting me into the modern digital world. I love my gadgets, but not sure I can swing the top of the line body. But do like being able to play with my toys and don't think I want a beginners model either, backward compatibilty is important as I have a lot of k and ka lenses.
