The announcement of a new canon 400mm lens at Photokina 2014 was not a huge surprise to Canon camera fans.
Rumors had been circulating for quite some time.
The new lens is the EF 400mm DO IS II USM which is the upgrade from the original EF 400mm DO IS USM.
The DO stands for diffractive optical, which essentially means great quality combined with small and light. Notice it has the green colored ring on the barrel and it is more affordable than the "L" Canon lenses.
It is definitely a beauty to look at, with its numerous switches and buttons:
The close-up photo below show the 3-position stabilizer mode selector, the IS on-off switch, the focus preset set button, the focus preset on-off sound selector, the 3-position focus selector and minimum auto-focus distance selector.
The sophisticated features of the new Canon EF 400mm DO IS II USM require a bit of study to fully understand how and when to use its various features.
The EF 400mm f/4 DO IS II USM is being marketed as a “portable super telephoto lens,” The chief design goal with this Canon lens was keeping it as light as possible.
Compared to the 400mm f/2.8L II, this second version of the 400mm f/4 feels really light in your hands as it weighs about only half as much. It claims up to four stops of image stabilization because of Canon’s OIS technology.
The lens features the newly engineered technology of gap-less dual-layered diffractive optical (DO) elements. That helps achieve optical performance while keeping the same size and weight of the earlier version of this lens and have the optical improvements to set it apart from the older 400mm f/4.

Here is a video to give you some more information on the new Canon 400mm lens:
Unlike the much more affordable Canon 400 f/5/6 lens that I use, this version is FULLY compatible with the 1.4x and 2.0X Lens extenders.
These prices are rounded off and change over time, but you can make your own personal judgement based on the comparisons.
400 mm f/2.8
I own the 400mm f/5.6, which is the slowest at f5/6, but it's the lightest to carry, it was the most affordable for me, and it is really sharp wide open at f/5.6.
My final comments on the new canon 400mm lens. Some photographers rave about the importance of the extra f-stop for getting great bokeh.
At 400mm, you have very shallow depth of field and it falls off quickly with this much magnification. The only really advantage of the f/2.8 over the f/4 is in low light situations.
If you have a recently made Canon, you've got exceptionally good performance at higher ISO settings,making that need of one extra stop of "fastness" less important.
At the time of this writing, you can't yet get your hands on one, or read the reviews yet, but you can get the thoughts of consumers who have used various Canon 400mm lenses here:
