It stands out to us because of the New Air Sphere Coating (ASC) that is used in its manufacturing. Basically, what it does is that it coats the lenses and makes sure that the chromatic aberrations that cause back lighting of flares or ghosting effects are minimized.

The EF 100-400mm f4.5-5.6L IS II USM is an outstanding lens for several reasons. The overall build quality is superb and there are many beneficial features included with the lens. Zooming with the new rotational zoom ring is very smooth and the tension can be adjusted from loose, where the lens will...

I've owned this lens since it was released... two years ago. Firstly, don't confuse it with it's predecessor, the mark 1. The mark I was one of the most controversial lenses, where people either loved it or hated it.

I have owned a number of large tele lenses, but the 100-400 stands alone in its combination of outstanding optics whilst staying super light. I know a lot of seasoned wildlife photographers who swear by this lens. Its great value, super sharp and very wieldy.

I have had one of these for a couple of years and I continue to be blown away by it. Canon has produced a simply stunniung piece of glass. The performance is so fast and smooth and razor sharp. It does have a bit of weight to it and the combination of my 5DmkIII weighs in at some 6lb.

The king is dead, long live the king! Seems as if Canon wanted to show the new mirrorless kids who is still the boss around. The Canon EF 100-400mm f/4.5-5.6 USM L IS was already good but the Canon EF 100-400mm f/4.5-5.6 USM L IS II is even better.

This is a great lens. When I borrowed on my son told me, "These are the best freakin pictures you have ever taken." The next day I purchased one from Digital Goja through Amazon. The questions I had were answered quickly. All the products arrived as promised.

Initially, I was hesitant to upgrade from my Canon EF 100 - 400mm IS I to the ISII. After all, I had taken some great photos with the original lens. My primary use of this lens is wildlife photography, for which this lens offers a practical alternative for those who cannot afford the 'big guns'.

This is an outstanding lens - definitely one of Canon's greatest. It also seems well priced in comparison to Canon's other super telephoto lens options.I've been using it professionally for over a year now.
