The exceptions are those lenses with very large front elements that are too big to accept threaded filters – the super-wide angle lenses and the really huge telephotos. These use internal drop-in filters instead. Canon have standardized their filters to a common set of sizes. The sizes used by Canon are typically: • 52mm. Used on the small primes, such as the 50mm 1.8 mark 1 and the 28mm 2.8, and on some earlier consumer/midrange zoom lenses. • 58mm. Used on the vast majority of Canon s midrange zooms. • 67mm.
