Hi, I have been doing photography for about 4 months now, and am really getting into it, and I want to get an slr, but do not know which one to get. There seem to be so many and I have no idea what would be best for me, what lens etc. I like shooting nature, landscapes, and close ups, but am still experimenting. Hope you guys can help, thanks! Btw, is it worth sticking with the camera I've got until i am more accomplished or not? Thanks!
