Hello, im still quite new to this forum, and if you remember i got into photography around xmas when i bought a Dimage 7 (with extras) from a friend for about 300$. and after my uncle heard of my intrest in photography he gave me his Canon EOS 650 with lots of goodies to me since he hasent used it in 7 or so years but i had a couple questions. Especially about lenses. Are new lenses that cannon makes compatable with the 650 ( sorry if thats dumb im still new to this photography thing ...but LOVING it) also how much is a fisheye lens? any advice for useing this camara?
