FotodioxLens Mount Adapter Compatible with C-Mount CCTV/Cine Lenses to Nikon F-Mount Cameras

I am VERY new to photography and found the device to be great for me as a beginner and should work as well for a professional. This tube set is for manual focus only. There is another set that has auto focus connectors for a few $ more, but I opted for manual focus so I could learn manual focusing on the fly. I have no complaints about this tube set. I ordered it on Monday and had it by Tuesday Morning. I called Fotoiox before I purchased it and got a CS rep on the phone within 3 minutes to confirm these would work with my camera.I found the parts locked together firmly. I have seen some reviews commenting on flimsy or weak connections, but I did not find the product to be weak or flimsy. I also mounted a Nikon 70mm-300mm and I did not feel the large lens would fall off... Just be sure to properly align the tube adapter to the camera correctly. The adapter will marry up to the camera in two different positions, but only one position will lock the adapter in place as it should be. If you attach the adapter to the camera and you dont hear the pin click into place, you are in the wrong position. The same goes for the marrying of the adapter to your lens. There are two positions that the lens will attach, but only one of them you can hear the pin click into place assuring the lens is locked.I used these tubes with:1. Nikon D3200 and my D3300 (I purchased this in 2015 for about $350.00)2. Nikon Nikor AF 50mm 1:1.8 D (I purchased this in 2015 for about $50.00)Things I had to learn while using this device:1. I had a small mishap (on my part) and had to call back after I used the device and tried to disassemble the parts. Beware! the small silver pin on the adapter that attaches to your lens slides in order to unlock and remove the lens. The instructions were not that clear. I called CS and again, was on the line with a rep in less than 3 minutes. He stated 40% of people call in because they dont understand how to slide the pin to remove the adapter from their lens.2. The lens I used to take the attached photos has manual focus and manual aperture control. The adapter plate that attaches your lens to the tube has a small screw on the sidewall of the adapter tool that will hold your aperture wide open. You have to remove the screw to allow the manual aperture to be changed.Finally, I love the device. The attached photos are my first time ever taking Macro type photos and I grabbed a dead mosquito in my garage as the model. I placed the mosquito on a blue business card and started snapping. Im sure with a better lens and flash, my pics would be better, but for my learning, I will use these tubes for years to come and just buy better lens as time goes on.

When I bought this, there was limited information in the description, so I bought it thinking it isn't much money, and it could be returned if it didn't do what I hoped it would. Stuff I wish I was in the description when I bought it:This adapter allows you to mount a fast lens with a 52 mm filter thread backwards on your F mount camera.This must be used in full manual mode on dslr cameras.This worked as intended with our f1.8 35mm lens.This will be less useful with slow lenses, because there won't be enough light to find focus. It worked, but not well enough to try to get any pictures with the 55-200 lense at 55, and didn't work well at all at 200 (to dark to see focus).On our 55-200 zoom lens at least, the zoom ring works as a focus ring, making it so you can get perfect focus on a tripod without a macro mount or moving the tripod. A fast extending barrel zoom with an aperture ring might actually be better with this than a macro prime lens (other than the the manual metering issue many cameras will have with that arrangement).Old lenses might have convenient aperture rings, but modern lenses will require you to manually adjust aperture against minor spring tension. At first I thought I would jam the aperture open with something (delicately), but it turns out that you need to adjust aperture to get good shots handheld. This is because you need light to focus, and you need depth of field to get good macro shots of most stuff (the F1.8 35mm reversed and set to f1.8 doesn't have enough depth of field to put the top and bottom of the mint mark on a coin in focus at the same time). If this paragraph doesn't make sense to you, you are unlikely to be happy with this item.With our 35mm lens reversed, we get somewhere about 2:1 reproduction ratio. That is both awesome, and somewhat frustrating. It is frustrating in that since working distance is how you focus, you can't back up to get a bigger area in the shot. It appears that longer focal lengths give lower reproduction ratios and greater working distances.Still, the image quality we get is stellar (as good as the F1.8 35mm nikkor is capable of frontwards).Unlike the screw-on-the-front macro adapters, or diopter filters, etc, the image quality seems to be as good as the lens you use it with. So picture made with this are harder to make, but excellent quality is possible, not just "excellent for the price."I freaked out when it wouldn't come off of the lens. No worries. The proper procedure for using this is to install it onto the lens finger tight, then install the lens onto the camera. When you are done with it, REMOVE THE LENS first, then the adapter from the camera. This does not have an extremely tight fit to the camera body, and pressing the release button, it comes right off.Update (12/2013): Shortly after the original review back in 2010, I ended up installing this to an old underwater camera lens purchased at full retail (used) for $15. The underwater lens is awesome in that the glass is excellent for the price I paid, and the manual aperture adjustment is a knob that protrudes from the side of the lens body. It was only so inexpensive because no one uses the camera mount it is made for anymore. I highly encourage others to use the same trick. The best photos I've ever taken (ignoring the value of documenting family events)have been with this reversing ring and the $15 old underwater lens. This also avoids the problems some others have had (which I have not) of getting the ring stuck on a nice lens.

Buen producto, buena calidad y buen precio

This product does exactly what it is expected to do. It allows me to use my Minolta MD 50mm f3.5 Macro Lens with my Nikon D4 lens mount.Made in China. Nice packaging. The front and back caps are great for storage of this adapter.Ignore the reviews that complain their auto focus does not work with this adapter. That is not what it is expected to do. It literally allows you to use a Minolta lens on a Nikon camera body.The non-CPU lens data function on your Nikon will be useless with this product as you are not mounting a Nikkor manual lens to your Nikon but a metal adapter. The turning of the aperture ring therefore is not recognized by the camera as a result.This is not a big deal.I have tested it with and without the extension tube I have for that macro lens and so far it works great.

Sem queixas.

Good adapter that let me play with my old 35mm camera lenses. Works well, slight play coupled to my Nikon but nothing that will affect your shots. No autofocus, get real, people complain that the autofocus doesn't work when they are using lenses from the 80's!!

Wow. Superb product. I have nikon d7500 with sigma 18-200 mm lens and it perfectly fits. I attached a sample picture of my kidney stone. That's 0.7cm in size. Thank you!!!
