I've just bought my first DSLR as a replacement for my Fuji S9600.
I was considering an Alpha A230, but ended up buying a 2nd hand 7D on impulse without knowing anything about it.
A SAL-50F18 and a SAL-1855 later and I'm very very glad I did. Still very much learning how to us it over the Fuji bridge, but when I get it right, it really shines.
