[Aluminum] I bought two of these C-Mount adapters to use for a 3D SMD soldering system. I am using two Panasonic CCD video cameras that require a C-Mount lens. These adapters are to Canon FD, I am using two Canon macro 50mm f1:3.5 lens. The output of the cameras feed into a 3D mixer box which creates a 3D video HDMI signal that is sent to a 3D monitor. With this system I can solder the smallest SMD parts by hand without problem. The adapters were a required part of the system, and they work great. It is a solid secure lens to camera adapter. An the anodized aluminum looks great with the black lens and camera colors.

[Aluminum] This lens adapter is super helpful if you are looking to buy older, more cheaper canon fd lenses for your Nikon! but cannon fd lenses and the adapter don't have ai or anything auto, so its an all manual lens, that can only be used in manual mode which is not a problem if you know what to do.

[0.265 lb] Exactly what I needed, it works flawlessly and produces great images. Thank you so much.

[0.265 lb] The adapter easily and securely mounted my Canon 500 mm f 8 mirror lens to a Nikon D90. This adapter does not support any lens or camera automation. You have to focus manually and set exposure manually. My 500 mm lens has a fixed aperture so manual focus and exposure was not a problem. The optical performance of the adapter is very good.

[0.265 lb] This adapter is simple to use, and expands your ability as a photographer ten fold. With it, you can use any Canon FD mount lens on a Nikon F mount body, just so long as the camera is in Manual mode. I had a lot of doubts before buying this, but I assure you, this will preform as you want it to. It is strong as well, I use it with a 3+ pound (about 1.5 Kg) 100-500 mm lens and it does not even flinch.

[Nikon F] CCTV zoom lenses are expensive ($199.00 & up). This simple C-mount adapter fits older 35mm Canon SLR lens to a 1/3 C or CS-mount digital CCTV camera, saving money by fitting recycled lens barrels from 35mm cameras for the digital age. See my ... listings at StationNT5Bmedia.

[Nikon F] I was worried that this adapter wouldn't work, and then I'd have no choice but to sell my collection of old Canon FD lenses. Luckily for me the adapter works great, and I am having loads of fun using my vintage lenses again, this time on a Nikon DSLR! Really wish I'd ordered it sooner. Thanks B&H!

[0.265 lb] Had salesmen trying to tell me it would cost $+ to get a converter lens that would allow me to connect my Nikon D90 to my old Canon auto bellows. This did the trick for $+. No trickery on getting it to work as implied by other reviews - very easy and straightforward.

[Aluminum] Shipping was fast and easy, website gave me all the info I needed to know for tracking. The actual product arrived and was exactly what I expected. Everything works, it's nice and sharp, putting the lens on is very smooth, very nice product. Had it for a few days now and I love it

[0.265 lb] Great way to get a feel for a new SLR lens without shooting a roll of film.
