I'm thinking of getting a digital SLR and would like some pointers regarding which makes/models to consider for my likely use. I enjoy close-up nature (plants & wildlife) as well as architectural and natural panoramic compositions. The key word for me is detail. We have many types of owl in our garden that are regularly close enough to be seen, just not close enough to photograph with my current Canon Powershot S40. If the same camera was also good for fast moving (birds in flight or Motor Racing) I wouldn't complain but these aren't my priorities. My budget is £500 absolutle top to start with, though obviously I can add additional lenses later. Anything immediately spring to mind? Should I look new or second hand? Cheers, Mark.
