Canon Ef 200Mm Lens

[37 mm] The filter is used with Canon EF-S 18-200mm lens mounted on Canon 60D camera and Nikkor AF-S DX 18-200mm lens mounted on Nikon D300S camera for both still photography and video shooting.

[0.515 lb] I've tested this Canon EF 2x extender lll with both my Canon 70-200mm L series lens and a Sigma 150-600mm DG contemporary lens. The image stays effectively sharp. There is definitely a little loss of clarity, but its not enough to stop me from using it at any given time. I'm quite happy with it.

[77 mm (Front)] Love my new Canon EF 70-200mm f/2.8L IS III USN Lens! I have used a Canon 55mm-250mm for long wildlife photo hikes. It had taken some really nice photos and light on the hikes. It is pretty well worn out now, so it was time for an upgrade. I still have a lot to learn about this lens, but it has already captured wildlife photos I was unable to catch with the slower lens.

[1/2" Bayonet] I was waiting for Canon Extender EF 2X III for a long while. I am very happy with it to extend the zoom to 400 mm on my Canon EF 70-200mm f/2.8L IS III USM lens which is the best lens I have. Lately I have been photographing Hawks, Hummingbirds and etc and find this Canon Extender EF 2X III gives me the ability to photograph at 400mm without purchasing another Canon lenses. With this Extender EF 2X III, the maximum aperture is smaller by 2 stops (f/5.6 for my lens). With Canon EOS 5D Mark III body, Canon EF 70-200mm f/2.8L IS III USM Lens and Canon Extender EF 2X III, it weights about 6.4 pounds which is a little heavy but manageable. Overall, I am glad I purchased this 2X Extender.

[Aluminum] I've used it with the Canon EF 200mm f/2.8 and TS-E 135mm and it works like a charm. Beautiful construction. Solid. Would recommend it.

[0.075 lb] Works great with the Canon COMPACT-SERVO 70-200MM T4.4 EF and the Canon COMPACT-SERVO 18-80MM T4.4 EF on the 6k studio camera and the Panasonic lens on the 4k cameras.

[Metal] I use this to attach a Canon EF 70-200mm f/2.8 L II and a Canon EF 50mm f/1.8 STM to a Canon M6 Mark ii, and so far the results have been outstanding. Also it's a much more economic alternative to the much more expensive Canon adapter.

[Zoom Control] Works great with the Canon COMPACT-SERVO 70-200MM T4.4 EF and the Canon COMPACT-SERVO 18-80MM T4.4 EF.

Works great with the Canon COMPACT-SERVO 70-200MM T4.4 EF and the Canon COMPACT-SERVO 18-80MM T4.4 EF on the 6k studio camera and the Panasonic lens on the 4k cameras.

[0.65 lb] Works fine so far with M100 body, EF 28-200mm zoom lens from my A2. Turn off the AF switch until you are ready.
