I got this for several of the 52mm lenses I have. It threads on smoothly with no wobble and is made of nice, thick plastic.

One of these lenses is a 18-55mm zoom used on a Nikon DSLR with an APS-C format sensor. The manufacturer’s description says not to use this hood on any lens with a wider field of view than 25mm to avoid vignetting (darkening of the edges of the photo). The crop factor for Nikon APS-C sensors is 1.5x, so at 18mm this lens has a field of view comparable to 27mm on a full frame digital camera or a standard 35mm film camera which is usually used as the reference when describing the field of view of lenses attached to cameras which evolved from 35mm film cameras. Look it up to get a better idea of what I’m talking about if you don’t already know. I’m not that keen on it myself.

Anyway, 27mm is uncomfortably close to 25mm so I ran some test shots of an evenly lit yellowish blank wall with the Nikon to check for any vignetting. The camera viewfinder is not 100% accurate so I had to go with the actual pictures. I found no noticeable vignetting at 18mm as long as the hood was oriented with the two largest “petals” pretty close to 12 and 6 o’clock. I found that to achieve the no-vignette at this position, the hood needed to be screwed in all the way – meaning that the lock ring had to be all the way snugged up to the body of the hood. A partial rotation of the ring to secure the hood with the petals at the correct position was okay, but even a few full “backwards” rotations of the lock ring which prevented the hood being screwed down as far as possible started giving me some vignetting.

Even locked down to the right position to start off there’s a slight rotation of the front of the lens to achieve proper focusing (unless you have one of those expensive lenses that have internal focusing), but the movement is fairly minor and didn’t give me any trouble. You probably will have trouble, though, if you screw the hood onto a filter and then try to shoot at 18mm! If using a zoom lens you could cancel any vignette by just selecting a slightly longer focal length at which to shoot.

Apologies for going on, but the take-away is that you shouldn’t have vignette issues using this hood at 18mm on a APS-C format camera. Canon has a 1.6x crop factor which puts you even farther from the 25mm danger zone. If you have a full frame format digital or a 35mm film camera, you would have major issues at 18mm. So, then don’t use any focal length under the 25mm mentioned. Of course, if you are using a zoom lens, you can use it fine at focal lengths greater than 25mm.

I don’t need to penalize this hood by taking away stars as it seems to be well made and does its job very inexpensively.

I used this adapter with a Fuji XM1 and a Nikon 50mm lens. I had no problem connecting the adapter to the camera and the lens to the adapter. It is possible to adjust the opening of the membrane. Excellent value for money.

I treated myself to a Leica Summicron R 50mm f2 for my Nikon D750 and now needed an adapter. This one is attached instead of the Leica bayonet with the 6 existing screws. (Please make sure that the small ball that does the rastering of the two doesn't get lost. All you have to do is put the bayonet up and slowly lift off the old bayonet ring!) The lens fits like one, and focuses cleanly to infinity . The camera does not recognize any lens data and there is no jumping aperture either, but the exposure is still great. The adapter is therefore really recommended.

There you go, I have a Yongnuo 50mm on my Nikon 1! In short, the ring does its job, the only annoying thing is that you can't adjust the opening. Only the speed is adjustable, so I only use it in very special cases. But this ring does its job and allows me to mount any Canon lens on my Nikon 1 and thus not invest a fortune in a Nikon 1 lens...

FujiX mount for a Nikon type 50mm f1.8 autofocus lens It was necessary to unscrew the Nikon side mount slightly to attach it and then screw it back in place. Works fine afterwards.

Bought to use my old Nikkor 50mm 1.8 Ai-s on an Olympus Pen E-PL7 as a portrait lens. The adapter pleases both visually and haptically and is very well made. Securely attaches to Nikon lens, securely snaps onto Pen's MFT bayonet like an Olympus or Panasonic lens. Nothing wobbles, no play. I have not tested the light tightness of the adapter against stray light under darkened conditions. The adapter is quite massive at 97 g, but this is reflected in a balanced weight distribution, a pleasant feel and also in a shake-free handling of the entire camera. In connection with focus peaking, manual focusing is really fun. I can use it to focus manually at least as well and quickly as I used to with the sectional image screen of the analogue SLR camera.

Assuming I'm a newbie to photography I can say that this lens does its job very well given its value for money. Unlike the 50mm Canon, the Nikon, which even costs twice as much, is much better made, the plastics are solid and don't creak, it has a firecracker ring which the Canon lacks, and the insert is aluminum. When you hold it in your hand, there is a feeling of robustness and solidity. As for the photo, it's a 50mm that does what it needs to do, focus is slightly noisy but not that annoying. Advice for anyone who is just starting out in photography and doesn't want to spend a lot of money on a lens. Soon I will also buy the 35mm. Today I also bought the 35mm f2... What can I say, it does its job. Solid and durable bright lens. I prefer 35mm to 50mm and I especially recommend it for those who make videos and are just starting out

ordered this lens for my Nikon D3300. The reason: I wanted to know what other lenses can do. At first I was rather skeptical and looked at some pictures, customer reviews and videos on the internet about the lens. There is a good video on YouTube comparing the YONGNUO to the CANON lens - be sure to watch the video beforehand (video title: YongNuo 50mm f/1.8 vs Canon 50mm f/1.8 II ) My conclusion: Up in any case, don't forget to remove the protective covers on BOTH SIDES of the lens. - The lens takes a tiny bit longer to focus (although almost not noticeable) and is also a bit noisy. - The focus ring is a bit too easy to turn, it seems a little less well made than Nikon lenses + The image quality is really good + Handling is easy + The workmanship is very good + Would be on the "Nikon" lens and not If it says "YONGNUO", you wouldn't notice. So, for anyone who wants to try a 50mm lens and doesn't want to pay more than 100€, this lens is recommended. And about the delivery: I ordered it via premium shipping on Wednesday evening and received it on Saturday, so it was really quick. By the way, the packaging is not "cheap" either, but looks very similar to the packaging of a Nikon lens.
