I got this lens to be able to reach out further than the 70-200 lens that I already own. This Canon 100-400 F/4.5-5.6L IS II lens is great. I've used it to take pics of both moving (ex - fast flying birds) and still subjects with great success (great clarity, color, etc.).

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...

Excellent lens, the zoom adjustment ring eliminates lens creep. I already owned the 70-300 f4-5.6L IS and 300 f4L IS lenses and so thought long and hard prior to buying this but decided to go ahead for the extra reach it would provide for wildlife photography, I have absolutely no regrets.

This is a very good lens. I had tried the old 100-400 F5.6 zoom and this new one is a different quality producing much sharper images and the auto-focus is also much faster and more precise. I also own the 400mm F5.6 fixed lens and both are very close sharpness at F5.6.

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 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.

An amazing lens for the serious amateur and professional alike. Just Google the product for reviews and there's nothing less than four stars. Many five stars! Purchasing through John Lewis and able to collect the product from my local Waitrose was simple and reliable. Delivery was within 48 hours

Great close distance focus Ideal zoom range Great image quality Built like a tank

Canon EF lenses are the best. This particular lens has great stability, lets in so much light and is light weight compared to the previous version.

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.
