Full Frame?

[michaelachan]

I read up about lenses alot of the time, and I keep coming across the term "full frame" and that certain lenses are not compatible with full frame camera's, could somebody be kind enough to inform me on what this means??

Full frame means the same size a a 35mm negative (34mm x 36mm). Digital sensors (excluding the Canon 5D) are smaller and lenses designed for digital project a smaller image circle, thus they will yield heavy vignetting on 35mm film or FF sensors.

This might provide some useful explanations,

Canon's EF-S lenses (or any sigma DC lens) will not be compatible with a full frame camera (such as the 5d), because the rear element of the lens is too close to the mirror and will not fit.

Also, EF-S lenses are only designed for canon's 1.6x & 1.3x crop factor cameras.

Its more to do with the physical image circle being smaller than the frame itself. However, in some cases you are right, you can do some severe damage to a full frame body by mounting an EF-S lens on it.

EF-S lenses will only work on 1.6x crop bodies.
