Canon EOS

Quick Question. I used to be well into photography, I own a Canon 35 mm . I'm thinking of buying a digital EOS my question is will all my Canon telephoto Lenses work on A digital camera.

As long as they are EF mount and not FD they'll be fine.

Thanks very much Roen

They may fit, but the sensor in many EOS cameras is a 1.6x or similar so your field of focus is much reduced. Means that a 400mm won't be a 400mm but likely a 600 and all that goes with that (loss of f stop and so on). Look it up on the web before you jump into digital with both feet. Might need to consider a whole new kit.

??? Loss of f stop? One of the advantages of digital is that your telephoto lenses become super telephoto lenses (without a drop in the aperture)! e.g. 200mm f2.8 full frame lens = 320mm f2.8 on a 1.6x crop sensor, 300mm f4 = 480mm f4 on a cropped sensor.

In fact the larger you go the larger the arithmetic gain. That's a great advantage for telephoto users. Vignetting and other problems with the edges of old lenses also are minimised (since the cropped sensor doesn't use the whole image circle cast by the lens).

Problem is that your wide angles aren't wide anymore... and every "normal" lens also gets shifted down the spectrum (sometimes onto an awkward focal length).

Canon also make 1.3x crop sensors and a full frame sensor.

Nikon make 1.5x crop and full frame sensors.

Olympus uses a 2.0x crop sensor, not sure about the others.

Sure, sure, but as opposed to below I was hoping to broaden the response rate a bit without giving the science lesson...

Thanks for the advice lads ,but without all the science involved will i be able to take photos with my older gear for the time been. I will invest in a good lense later on . the camera I am buying is a canon 400 D body only. The lense I intend using of my older Canon is a Canon zoom lens ef 28-80 mm. I'm not too worried about loss of performance provided it works . thanks

yeah moro, it'll work perfectly... the only difference being you'll get an equivalent focal length of 44mm - 128mm

thanks thats all I needed to know minikin.
