Yes. EF-s lenses won't.

Full frame camera is one with 24x36mm sensor. So currently Canon 5D or 1DsII.

Full-frame sensors are 35mm sensors; the same size as a 35mm film camera. Consumer and prosumer DSLRs use smaller sensors, normally something equivalent to APS size. That results in a 1.5:1 or 1.6:1 adjustment. In other words, a 100mm lens on a DSLR would have the same perspective as a 160mm lens on a film camera.

There has been a good bit of confusion about this, with some referring to it as "magnification". The sensor does not "magnify" anything; the field of view is different based on the sensor size.

All EF lenses will fit on any Canon camera (full frame or not). EF-S lenses have a smaller circle of view and will only fit on cameras with 1.6 multiplier.

The reason EF-s lenses won'twork on Canon cameras that have a larger imaging chips (EOS 5, 1D mk.2, 1Ds mk1 or mk.2) is that these cameras have larger mirrors and the rear element of the EF-S lenses will hit the mirror. This is according to Chuck Westfall at Canon.

I am pretty sure the lens you mention in your first question lens will work on these higher end cameras.

Like others said, a full-frame camera in the 35mm-based world is a camera that captures images approximately 24x36mm.

All EF lenses (NOT EF-S) create images that large and can be used on full-frame cameras. EF-S lenses cannot be used on full-frame cameras for several reasons (optical and mechanical).

Note that with a 28-135 on a 350D you won't be able to capture wide angle pictures.

also as a side note. just to add. EF-s lenses stick back farther inside the camera body. this will result in mirrors hitting lenses if you do manage to put an ef-s lens on a ff camera body. I don't know if this is the case 100 percent of the time and if you are willing to try, you can measure clearances and play with this option. Some people modify their ef-s lenses to be able to fit in EF only lens mounts, but only for putting particular lenses on the 10d which isn't ff.

anyway have fun with that lens, it is not a bad lens at all.

In addition to the physical limitations (mirror whacking) EF-S lenses create a smaller image circle than do standard EF lenses. This means that the area of light they project into the camera is not as large in diameter as that emited by a "full frame" type lens. This would cause (assuming you somehow attached an EF-S lens to a FF body) severe vignetting, by which I mean that the edges and corners of the image would be dark and without image information.

Andrew Hinkle , Sep 13, 2005; 03:53 p.m.

By the way, if you have more questions regarding EF lenses and canon bodies you might wish to post directly into the canon EOS forum. People there will have more specialized information with which to help you.
