The digital camo TravelCoat for the Canon 400mm f/4.0 DO IS AF Lens from LensCoat is a 3.0mm-thick, shock-absorbing, closed-cell neoprene lens cover. It was designed to fully protect the lens when it is not in use, without the need for a more comprehensive lens case. It allows more valuable room in your camera bag for other necessities. The coat slides over the lens, and closes with a secure touch fastener. Digital camo is an advanced computer generated pattern modeled after the U.S. Army's standard-issue ACU pattern. It features pixelated rectangles to maximize visual break up. The pattern mimics naturally occurring dappled textures and rough boundaries.

Q: 6. this lens works automatic focus with the Canon Extender EF 1.4X IIIThanks Fernando

Q: 7. why would i purchase this lens instead of the 500mm L?

A: Portability. It is equal in sharpness to my 500L IS (the first version, which is a great lens), but weighs half of the larger lens. It loses nothing to a 1.4x extender (except a stop of light), so at 560mm and f/5.6, I have a lightweight lens I can carry through the woods all day. When I expect to be tethered to a tripod without having to move much, I'll use the 500, but to be honest, I haven't mounted it since September when I received the 400 DO II. I'm 60 years old and no longer able to schlep the 500 around like I used to...

Q: 8. I have a Wimberley WH-200 gimbal head. Which quick release plate will fit on the 400 DO II?

A: The hood still fits when reversed with the RRS replacement foot.

Q: 9. what size is the thread on the tripod foot?

A: 1/4

Q: 10. Does this lens have autofocus with the EF 2x III extender?

A: When using the 400mm f/4 with the 2X III Extender, you will retain autofocus with the 1D series and the 5D III with the newer firmware. With all other cameras, autofocus will be lost.
