EFS-S lens

[round]

Hi There,

This could just be a dumb question to the experts.

EF-S is specially made/designed for the 1.6X dslr so does the focal length on the lens (say, 10-22mm) already included the 1.6x factor or I still need to add that 1.6x factor.

Ta.

still need to add the factor

If you don't shoot with 35mm film you can ignore the 1.6X crop factor. Really, just ignore it, it causes confusion and arguments. A 10-22mm EF-S lens will make a wide picture with a unique perspective. Who cares what you need on a 35mm camera to make the same image? Not me.

The only thing to beware of with an EF-S lens is it won't work on a 10D, 300D, or any 1 series camera. If you don't plan to upgrade to a (really expensive) 1 series, it doesn't matter. Even if you do plan to upgrade, many people keep their older camera as a backup.

Not that it really matters, but a 300D is EF-S compatible I think, the 10D is the only 1.6x crop DSLR that isn't.

Oops, my bad, I knew that because I had one! You get the point of my post tho.
