L lens of Canon is the most feature rich aspherical Lens for DSLRs. Cost of a L lens is few times higher than its normal EF Lens counterpart. The most asked question is why Canon L Lens is named as L Lens.

Usual Characteristics of a Canon L Lens
L Lens is NOT a standard word associated with Digital Photography, it is Canon specific. Quite obviously, the characteristics varies. For example, we have stated that L Lens is for DSLRs, but there is Compact Digital Camera from Canon, that has fixed L Lens. Still, there are some typical features present in L Lens :
- Along with aspecrical optic components, one fluorite or ultra low dispersion glass element is present.
- Front does not rotate – this is to make the usage of special effect filters more effective.
- USM is of finer quality.
- Usually the size and weight is higher than EF counterpart.
- Usually the body of longer ranges is a combination of Metallic White and Black with a red ring around the front part of the lens.
