Hi I am a newbie in photography. Used to own a Canon SLR and 2 original Canon lens. However, now thinking of getting a DSLR. Pls advise if my current 2 canon lens for my SLR can be compatible for a Canon DSLR or not? I tried fitting and taking pic and had no major problems but just wondering what are some disadvantages in doing so. Should I save some money by sticking to Canon with my old SLR lens or buy DSLR body (other brands + other lens) eg.Nikon D90? Thanks for advice.
