I purchased this adapter to use a couple of Rokinon lenses for astrophotography on my newer Canon DSLR.

The adapter goes on without effort. Removing can be tricky but at first but removes easily once you identify the release button (see photo). Press the button and rotate clockwise to remove from the lens. There are no instructions provided which would be nice as removal is not intuitive out of the box.

The metal portion is glossy (smooth) which I appreciate. Many adapters have rough (mat) finishes that seem to be rough on the lens mounts.

I would recommend!

It was a bit of a snug fit with my NIKKOR 50mm 1.4 but fortunately it has enough clearance that removing the adapter was pretty easy.

The adapter is well built and sturdy I would absolutely get more of these adapters for future NIKKOR lenses!

I haven't used it much yet, but it's really a very well-made adapter, nothing like the cheaper ones for a few euros. Stable, precise and without any play, it can be assembled and disassembled easily.
a really good product, worth spending a little more for!

Worked great on my Canon EOS, allowed me to use old lenses perfectly. Good quality.

I bought this adaptor for an old manual focus Vivitar Series 1 90mm Macro lens. This is a superb lens for film or digital and I wanted a lens adaptor which was economical but would work smoothly and retain as many functions of my Canon cameras as possible.

I tried a Fotodiox adaptor but the fit was very rough and too snug on my Canon EOS 5D Mk1. And on my Canon EOS 650 35mm film camera it was too loose and would not let the meter read properly. All I got was an "EE" total error. So I took the FOTODIOX back for a refund at the camera store.

I found this adaptor by K&F. I don't have any other lens adaptors from this company but heard good reviews. It's a little more than the FOTODIOX. But at only $5 US more it fit my budget. When it arrived I first put it on the EOS 5D body. Perfect fit! Snug and smooth. And more important it UNmounted just as smoothly. Fotodiox product was difficult to remove. But the K&F came off like a Canon lens should.

Then I put the Vivitar Series 1 lens on the adaptor. Also perfect! Focused to infinity and perfectly at very close Macro distances as well. Av and Manual mode metered perfectly as well, measured against my Gossen Luna Pro handheld meter.
I next mounted both on my 1987 Canon EOS 650 35mm film camera, which I've had since it was new. I still shoot a lot of film for its unique look. I was surprised that the K&F adaptor went on smoothly and retained Av metering-even in Spot mode on this first EOS camera ever made! I like this adaptor so much I'm tempted to replace many of my Fotodiox lens adaptors with their brand. In any case I know that any new lens adaptors I purchase will be made by K&F

Very good quality. Solid and precise. Nikon 50 mm on Black Magic Ursa with EF mount.

Used to adapt some vintage lenses, including Carl Zeiss, to Canon EOS DSLRs.
The model I chose only requires a mechanical adaptation, and not an electronic one, it works well and I have used it with satisfaction, after 7 years it still works perfectly, made with solid materials and right tolerances.

Yashica lens adapter perfect for my Canon 1200D! I recommend it to anyone who would like to use old analog camera lenses on their SLR.

shipping OK, packaging OK and item intact.
Although the price is cheap, you can see a good workmanship and the adapter is solid.
Very easy assembly, I personally used a 50mm f/1.8 lens from the 70s, first mounted on an Olympus OM-1. Initially the attachment seemed a bit ""shaky"" to me, but in the first tests I had no problems whatsoever.
Focus and aperture obviously work in manual, but the other functions remain as if you had an EF-S lens.
Fully satisfied.

Version Purchased: Lens Mount Adapter Nikon G (D-Type) Lens to Canon EOS Camera - K&F Concept - adapter ring from Nikon (AI-S, D, G type lenses...) to Canon (Camera Body)

I purchased this adapter two months ago and I can say that I was lucky in my choice because compared to the adapter rings that other friends have, it is clearly of superior quality (since the lens used does not have any play whatsoever, most of the cheap ""Chinese"" adapters, in the range between 15 and 30 euros, have poor quality control, many can be either too hard or even too ""shaky""); Both assembly and disassembly are simple, you just have to be careful and remember to press a small lever before disassembling it. Once mounted, it has a feeling of stability, practically as if a lens had been mounted directly on the camera body.
Given the good quality of my sample, the price of 21.88 euros is absolutely fair.
That said, some recommendations and clarifications:

- a limit of this and similar products is that linked to the information that is not there or is very little (in the absence of a chip, which must be purchased separately, especially in China and the latest generation, programmable, should cost around 20 euros.)
On a Canon body it allowed me to comfortably use Nikon lenses in manual, autom. with aperture priority, with exposure meter operation, and evaluation directly in the live view as well as the exposure and focus.

- Unlike other adapter rings, it also has a lever that allows easy adjustment of the aperture, even if the exact value cannot be established. Even using the reflex as a video camera, shooting videos you have a more fluid control of the aperture, without rotating any ring on the lens that often creates oscillations in the camera.

From the above it can be deduced that to operate correctly it is much better to work in Live-View so as to be able to control exposure and focus.

-Another consideration is the one related to the diaphragm of the lenses: both lenses with an aperture ring (AI, AI-S and D) and lenses without such a ring (G) can be used easily; with most adapter rings with Nikon G you can ""not easily"" work only by blocking the lens diaphragm lever with a small spacer (I use for example a small piece of cardboard, toothpick etc..) of a suitable length depending on the aperture of the diaphragm at which you want to operate, consequently operating in a very empirical way. And therefore every time you want to change the aperture of the diaphragm, without this adapter ring, you have to remove the lens from the camera body.

- I have extensively tested this adapter ring with a Canon 700D body and a quick test on a Canon 70D. The NIKON lenses tested range from an "older" 55mm F2.8 Micro AI-S, up to recent lenses such as 18-105 G, 70-300 VR G. I also tested TAMRON, TOKINA and SAMYANG lenses. Even discovering that the 55mm MICRO and SAMYANG, manual lenses also on Nikon, were easier for me to use on a Canon body thanks to the better functioning of the liveview and the working exposure (not on Nikon D90).

Having said that, I passionately support the use of all types of adapters, which even if at the cost of some sacrifice or limitation, allow us to use sometimes excellent lenses at a very low cost, often with excellent results; and above all they go in the direction of a greater ethics of consumption and use, greatly reducing the economic obsolescence of many products that are still very valid.

The package arrived efficiently protected and the shipping was fast. I thank those who have reviewed this product before me, guiding me towards this choice, and I hope I can also help someone in the guide (often in the dark, given the lack of information) of an adapter ring from Nikon (lenses) to Canon (Camera Body)
