Canon 400Mm F/4

[58 mm (Front)] Youd think for the price this would have some flaws. At f.1/4 its pretty sharp at f.2 its razor sharp. I did not look at the outer edges of the frames as Im concerned with my subject. Good buy for the price.

[Arca-type] I use this on a Canon 400MM lens. Mount holds the the lens securly but heavy.

[8.85 x 7 x 3.3"] Great, heavy duty strap for the Canon 400mm. Quality product and looks fantastic.

[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.

[0.455 lb] I use this with the Canon EF 400mm F4 DO and it is really an essential accessory for the lens. The Canon one is bulky, heavy, and is a pain to get on and off. This one is lighter, quick to get on and off, and can be put on the lens when in storage with the hood in reverse, hood on normally, or even just over the front of the lense without the hood. It stays one and does what it should. The little loop on it is also useful for attaching a cord to something like your tripod ring so you don't lose it or let it fall on the ground. This is also the most economical and reasonably priced product in the entire LensCoat line of products in my opinion. At sub $30, there should be no hesitation in purchasing this to protect your lens.

[0.17 lb] I purchased this product to replace the market lens foot on the Canon 100-400mm f/4.5-5.6L IS II USM Lens. The quality of the materiel is excellent and I would recommend this product. It fits all of the Arca style plates and is easy to install. It is a little bigger than the original lens foot, so it may take some getting used to. If your hand-holding the lens, it may be easier to rotate the lens foot to the top of the lens for better access to the zoom tension and focusing rings. Other than that, I think this is a great addition to the lens. See photo below.

[Canon White] The lens cover for the Canon 100-400mm II works well. It provides protection from bumps and scratches. It helps resist rain, moisture and colder weather.

[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.

[4.5 x 4 x 0.75"] Purchased this for my new 100-400mm Canon Lens. Put it on immediately after removing lens cap for the first time. Images looks sharp!
