Outstanding Performance
on September 8, 2012

The Canon 400 mm f 2.8 MK II is outstanding in all aspects. The f 2.8 opening provides superb images wide open, the weight has been significantly reduced allowing for its handheld use for photographing birds in flight for up 3-4 hour (personal limits). It weight reduction also is a great advantage when carrying in the field with a tripod. I use this lens with the 5DIII and the autofocus performance is incredible delivering a 95-98% of in-focus images. When used with a 1.4X Canon MKIII image quality degradation is not noticed. I replaced the foot with one that provides a lower height profile, lighter weight and a built-in groove for mounting to ballheads without the need to use a mounting plate.
Pros: Fast auto-focus, Superior build quality, Super-sharp images, lightweight
I would recommend this to a friend!

perfect comes with a price

After years of lugging heavy lenses back and forth on the NFL sidelines, this lens is a real treat due to it's reduced weight. This lens can actually be held held. While I don't see a tremendous difference in sharpness over my previous 400 2.8, the aesthetic quality of the bokeh seems to be more pleasing than the earlier version. The colors seems to be richer with added saturation. I've also added the 1.4 III which doesn't really seem to slow the lens down that much in terms of focusing speed. I'd rate this lens a 9.9, I'd give it a perfect ten but everything has room for improvement.
Pros: drastically reduced weight, location of controls, improved bokeh, can be hand held, richer color saturation, improved image stabilizer
Cons: cost

Impressive

I rented this lens for 1 week this summer when I had some cash in my pocket and I was looking for a hand-holdable lens to mount on my 7d that offered more reach than my 70-200 for nature/birding. After quite a bit of internet research I was torn between the 300 2.8 II and the 400 2.8 II.
I'll start by saying that this lens is nothing short of spectacular. If you can afford it and carry it for your intended/expected durations then I wouldn't hold back on it! It is really a joy to shoot with this lens. I'm not a great photographer (more money than skill), but the images that I captured with this lens after spending a few days of quality time with it were flattering to my abilities. I used the lens freehand for some outings and with a monopod for others. I sometimes used my 1.4x extender and noticed no appreciable tradeoff with AF or IQ performance.
At the end of one week, however, my shoulders, back, and arms were paying the price for carrying this lens around. For once-a-week outings I'd probably be fine with this lens, but I was really hoping for something that I could haul around on my annual Adirondacks vacations. Those trips are 10 days long with ~5-8 mile hikes on a few days - sometimes climbing ~4000 ft. hills - and I knew from my short experience with this lens that I wouldn't be able to take it with me through those conditions.
I almost wish that I could ignore my annual hiking trips when considering this lens, since I know that it would be more than manageable for one or two days at a time, but I ended up getting the 300 2.8 II and I'm really happy with my decision. Maybe someday I'll once again have enough cash in my pocket to get the 400 2.8. I'll buy it in an instant knowing that the 300 2.8 II is in my bag.

Great Lens!

I got this lens to replace my 400 2.8L VI. I really like this lens but I have to say I cannot see a real big improvement over the IQ, between VI and VII. If I had to do it all over again, I may have kept my VI. I am not unhappy at all with the upgrade, I just may have been expecting to much. Still a great lens and would recommend it to anyone.

It is an excellent lens! I use it with my Canon EOS-1D X camera. Actually I have some Canon L series lenses such as Canon EF 200mm f/2L IS USM, Canon EF 24-70mm f/2.8l IS II USM, Canon EF 85mm f/1.2l II USM, Canon EF 14mm f/2.8l II USM, Canon EF 100mm f/2.8l IS USM, Canon EF 70-200mm f/2.8l II IS USM and of course my new Canon EF 400mm f/2.8l II USM. I use my another lovely camera Canon EOS-5D Mark III. I like this new lens very much! The picture quality is excellent!
Pros: Fast auto-focus, Superior build quality, Super-sharp images
