Pros: Optical quality, build, handling, AF, IS
Cons:
New price is still high

Last fall I decided to replace my EF500mm F4L IS and 300nn F2.8L IS. Both lenses were getting old and have been taken out of service life by Canon. I really wanted something lighter and easier to handhold and travel with. With all the hype about Nikon's 500mm and 300mm DO versions I looked into the 400mm F4 DO2. Found a great deal on a used lens and jumped on it. So the 400mm replaced my 300mm and 500m. I also have the 800mm F5.6L. Been using the lens for 3 months now and I'm very impressed by it. I've used it with my 1dx, 7d2 and 5dsr. The lens is very sharp, AF and IS is excellent, better than the 500mm F4 and the 300mm F2.8. Takes the 1.4x and 2x MKIII's very well. It's a joy to handhold. Here are my observations.

Image quality (sharpness)

400DO =300mm F2.8L IS
400DO >500mm F4L IS
400DO+1.4x = 500mm F4LIS
800mm F5.6L >400mmF4DO +2x (close)

AF

400mm bare excellent with 1dx, 7d2 and 5dsr
400mm + 1.4x with 1dx excellent, 7d2 5Dsr very good
400mm + 2x with 1dx very good, 7D2 & 5Dsr fair. Handled larger birds in flight quite well.

OOF backgrounds or Bokeh looks very nice and smooth no funny highlights.

Overall I'm very happy with my choice and don't feel I lost anything by my decision

Pros: Extremely sharp optics, Much improved IS, Fast focusing, great balance
Cons:
Pricey but thats the trend these days however compared to the competition... Wait there is none!

I've used many different telephotos over the years and replaced my 600mm F4IS with this lens while holding on to my 500mm F4 and 300mm F2.8. This is without question the best supertele I've ever used. Extremely sharp with great IS that I've been able to handhold effectively down to 1/60th.
The lens is very well balanced, much better than the 600mm and handles very well. The weight reduction is much appreciated and after replacing the lens foot with a 4th Generation design foot the lens is practically as light as my 500mm. Tripod collar design is much improved and the lens roatates much smoother than the 600mm, 500mm etc. I've also noticed this lens focuses faster with all my cameras that the 600mm did. A simply stunning lens............
