Canon 400Mm F 5.6 L

[0.485 lb] I bought this adapter in order to use the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens with my Canon EOS R6 MkII. It works flawlessly!!! It is solid as a rock and there is no noticeable difference between using this EF lens and adapter to using an RF lens with my camera. I don not hesitate to recommend this adapter to anyone.

[Bandpass] I got this filter because my results on my Canon 400mm 5.6 with a Hoya HMC 77 UV(O) were drab. With this new filter I have brilliant color and contrast and can enjoy vivid pictures. I am happy with this purchase.

[Black] The Lens Cover for Canon 100-400mm f/4.5-5.6 IS II (Realtree Max4 Camo) by LensCoat it one of the best I have. I have used many different one but they do not fit like Realtree Max4 Camo covers and nice feel when holding it. easy to install and most of all looks great.

[Aluminum] I'm using this lens plate on my Canon 400mm f/5.6 L lens on a Really Right Stuff BH-55 ball head with full size screw type clamp. The safety screws are narrowly longer than the ball head clamp and the dove tail fits nicely into the RRS clamp.� The plate works as intended.

[0.16 lb] I use these extension tubes on with a Canon 400mm 5.6L for photographing hummingbirds at close ranges. These extension tubes are well made and keep autofocus in really tough scenarios.

[Yes] This is the perfect foot replacement for my Canon 100-400mm EF 4.5-5.6 IS II. By replacing the lens's foot, the mount is much more stable than adding another Arca-Swiss plate onto the OEM foot to attach it to my gimbal. Expensive, but needed. There are other foots out there, but RRS engineers their stuff really good, it fits perfectly and very easy to install and remove.

[0.45 lb] It's a 400mm f/5.6, internal focus, and that wonderful Pentax AF/MF slider mechanism on the focus ring. I just can't get over how ridiculously long the setup is when locked on the front of a 645D. It has detents at 90 degrees on the rotating collar. It comes with a carrying pouch with neck strap.

[82 mm (Front)] If Sigma would also make 400mm f/5.6 lens of the same quality, everyone would praise Sigma. But Sigma does not see the value of the 300mm f4.0 lens, 400mm f/4.0, or f/4.5 or even f5.6 lens. Instead, Sigma is getting addicted to 10mm-1000mm no value zoom lens...
