Lenses

[Rod Daldry]

Im confused.

I have an old Canon EOS film camera and lenses for the same - if I buy a Canon EOS DSLR can I use these lenses? I know they will fit as they have EF/EOS mounts but will they work effectively given that the sensor area is rather smaller?

Yes. The EF lenses will work on both cropped sensors and full frame sensors. It's the EF-S lenses that will only work on a cropped sensor, but not on full frames. From what I understand, if you put an EF-S lens on a full frame camera and click the shutter, the camera implodes and the universe ends shortly after.

If anyone would like to validate this claim by trying, please keep me posted on how it goes.

@daldry I quite happily use my old film EF SLR lenses on my Canon DSLR. If your EOS DSLR has an EF-S cropped sensor, you factor this in, so an EF 35mm on a 1.6x crop DSLR gives a similar field of view to what a 50mm would on your old camera and so on. You'll see this referred to as 'equivalent focal length' in some lens descriptions.

@gurry They won't need to tell you. You will figure it out when the universe ends! ;~}
