Hi
Thanks for all comments.
I have to agree with you I am really confusing myself and more information I get, more confused I am becoming. What can I say about my skills. I haven't done any shooting with SLR, yet. Right now I am using Canon Powershot camera. I have been taking my photography a bit seriously for the last year or so. I have understanding of shutter speed, aperture, ISO, etc. Honestly I even don't understand really what is actually the difference between SLR and compact camera (except in technology and in fact that SLR produces better pics) - I mean in terms of usage (hopefully the question doesn't sound to silly, but as I just wrote I haven't used SLR yet). I try to practise as often as possible and try to take photos practically of everything, but I enjoy the most in shooting landscapes and wildlife.
I haven't limited the budget. Right now I am doing a bit of research and I'll probably weit for a couple of months to save some money - how long I'll have to wait before buying depends of the camera price (but of course, I rather spend less than more if it is possible).
