I was wondering if anybody knew anything about the old MF 35mm SLRs and the more updated ones with auto function. I have a newer one (Canon 3000) but am looking to replace it with an older manual one as to me it seems you get a wider aperture with these cameras. Does anybody know anything and is there much difference?
@missclow You don't get a wider aperture with those cameras. The aperture is all in the lens, and you can use many lenses interchangeably between a film and a digital SLR.
If you mean you get a full frame sensor on those cameras, then yes you're right, which means the lenses you use will be wider. But you can compensate by choosing the right lens. The Canon you have has a x1.6 crop factor, meaning any lens you use will be 'magnified' by 1.6 (so a 50mm becomes an 80mm). But you can compensate, so say you want to use a 50mm equivalent, just use a 35mm lens (as 35mm x 1.6 = 56mm, or use 28mm as that equals about 45mm).
Thanks! Not sure what you mean by full frame sensor and lens size though! Basically, if I get an old 50mm manual lens for my canon, will that work the same as an old mf 35mm?
Be careful with Canon lenses, because they have to be 'Canon EF' to work on your camera. If you look at the ring where you put your lens on to your camera body, you'll see two dots - one red, one white. The white one is for digital only lenses on most Canon bodies; the red for older lenses that work on both film and digital.
Old SLRs had full frame sensors, whereas digital sensors are usually smaller on most DSLRs. Because they're smaller, they capture less of what you see, meaning lenses need to be wider to capture the equivalent of what an old SLR would. So, a 50mm on an old SLR would be 50mm, whereas you put it on a Canon and it becomes 80mm (because it essentially magnifies what you see by x1.6).
Vikdaddy is correct - the aperture is in the lens and not in the camera.
One thing to look out for when buying old manual lenses or cameras is canon's older 'FD' lenses don't work with newer 'EOS' system. When Canon changed to autofocus in 1987, they changed the entire mount. You'll probably want to just stay clear of these cameras ans lenses.
