From another forum I heard that the shutter of the Canon 10D 'only' lasts about 50.000 shots (1388 films). Allthough it seems much, the advantage of having a digital camera is that you can shoot a lot more then when using an 'ordinary SLR'. I do shoot a lot of films with my analog SLR and expect to shoot way more when going digital.... Should I be concerned about that number of 50.000? Anyone experience with that?? Shutter replacement could get expensive, not?
