Canon 75 300Mm F4 5.6 Iii Usm

[6.05 x 5.8 x 1"] I used this on a Canon 5D III with 300mm F4 and 70-200mm F2.8 lenses. It was a good size for either. On an ocean trip with moderate salt spray and in rainforest rain, the camera was always dry.The eyepiece hole takes a few seconds to pull into place, but it's easy. It also takes a few seconds to get your hand into the sleeve when damp - I just keep my grip on the camera between shots.I do recommend having more than one of these handy. They are not meant to last forever, and can split along the seams. I'm still a happy customer, because these are so much cheaper and lighter than the heavy-duty covers.

[Multi Coated] Fantastic lens. I love my EF 70-300mm f/4.5-5.6L IS USM, but this fixed lens is so much crisper and better in every way at a fixed 300mm. Even with a 2x extender it's super crisp compared to my old lens.

[Black] This is one product that is able add the 'wow' into your photographs with the new Canon 300mm f/2.8L IS II USM and the 400mm f/2.8L IS II USM lenses. With this accessory, I use several B+W ND filters to allow lower shutter-speeds as required.

[0.35 lb] My canon 50mm is usm F4 I bought was missing the oem hood and this was a very nice option it fits well and serves my needs, I also got one for my Tamron 150-600mm

[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.

[0.69 lb] Was experimenting with this big canon lens on my Olympus OM-D E-M1 MkII M4/3. Did not want to settle for f/4 OLy. 300mm. Wow it works great. Auto focus-fast. Stabilization- either the lens or the cameras stellar IBUS; the lens is is better! Ver.2 of this lens would work even better. Next tried ver3 of the 2x converter. Auto focus- slightly slower in lower light. Stabilization-less but good. Also bought speed booster. Now one lens and 4 lens choices 213mm f/2, 300mm f/2.8, 426mm f/4, 600mm f/5.6. The 35mm equivalents are 426,600,952,1200mm. The optics of this canon lens are so superior that even the 600mm f/5.6 images are sharp + contrasty .

[Zoom Gear] Works very well with my Canon 200D and both my Canon EF-S 55-250mm f/4-5.6 II and Canon EF 70-300mm f/4-5.6 IS USM lens.

[Manual Focus] It is wonderful at f8-11. But at f4-5.6 its --ludricrously-- sharp. Image from canon 5d mkiv...I've compared this image to a friends Nikon d850 with 14-35-raw file at 50-100%. 30-vs 45 mgpixels. No comparison. The Canon Zeiss wins. Your mileage may vary.

[Yes] Fits a Canon 70-300 F4-5.6 L series with the hood reversed and the EF-RF adapter attached. A little bulky, but good protection (much better than the wimpy bag that Canon considers a case).

[Yes] Works well with my Canon EF 75-300mm lens on my Sony A 7II camera. Manual focus only
