Overview of Canon Lenses
This section covers Canon-brand lenses.
Canon’s lens line
The “L” lenses
Canon’s “L” line is designed for professionals: high quality build, more advanced and higher performing optics, which is not to say that non-L lenses are inferior; many are excellent. But in general, if you can afford it, you’ll want “L glass”, the stuff with the red ring at the end of the lens barrel.
EF vs EF-S lenses
The EF designation means that a lens is designed for a full-frame 36 X 24mm sensor.
The EF-S designation means that a lens is designed for a smaller cropped sensor, 22.3mm wide.
