L-series Lenses

No lenses have a better reputation among professional photographers than those in Canon’s L-series. Identifiable by a bold red ring around the outer barrel, these lenses are distinctive in their performance through use of optical technologies like Ultra-low Dispersion UD-glass, Fluorite and Aspherical elements and Super Spectra Coating.

Fluorite / UD Elements
Avoiding color fringing, or chromatic aberration, has been one of the great challenges in the design of telephoto lenses. L-series telephoto lenses—like the EF 70-200mm f/2.8L USM utilize Canon’s Ultra-low Dispersion glass to minimize this effect.

We also use the Canon Tele-Extender EF 2x II to double our lens to a 400mm for some of our more distance shots. More information available soon

The only thing we would do different if we were to replace this lens, would be to spend a few extra dollars and get the IS (image stabilized) version. Although this EF 70-200mm is a f/2.8 lens and makes "fast" photos, when shooting from a moving platform such as a boat, the IS (image stabilization) will add an extra ounce of stability.
