The 'K&F Concept 67mm UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter with Lens Cap' arrived in a branded box.

The lens is in a plastic case for protection, it also serves to protect one side of the filter, whilst the opposite side is protected by the lens cap.

The filter was an easy fit to my Nikon P900 and as it is slightly wider than some filters I found it easy to unscrew after use. I would however recommend carrying a suitable filter wrench just in case.

It would be nice to see a cover for the side of the filter not protected by the lens cap a the lens filter with cap attached are stored in a cellophane envelope in the case, I suggest putting the filter/cap combination into the envelope with the lens cap the same side as the flap which keeps the adhesive as far away from the lens as possible.

It would be nice to see a protective cover for the second side of the filter, maybe something push on.

This worked perfectly - and fitted easily onto the front of my Nikon 18-70mm lens. The lens cap that comes with it even makes it easy to attach. I couldn't tell any difference in image quality when using the filter (other than the effect of the polarizer). Really happy with it.

The "K&F Concept 67MM Polarizing Filter Circular Polarizing CPL, Ultra Slim, Japan Optics, Multi-Coated, with Lens Cap" came in a branded box. It was nice to find the filter in a hard plastic case for protection, with a lens cap already attached to the filter. I ordered this filter for a Nikon P900. With the lens cap still attached to the filter, I carefully screwed the thin filter into place. I then took a series of pictures to check its effectiveness, and have included two pictures of the original Nikon lens cap showing the difference. When attempting to remove the filter, I found that it was stuck, so I had to resort to a filter wrench to remove it. The reason it got stuck was because I was turning the polarizing ring clockwise and counterclockwise from my perspective behind the camera. I must have just caught the threaded ring with my finger as I turned it counterclockwise, just enough to lock the filter in place. Some suggestions I have from using the filter; 1. When installing the filter, leave the lens cap on as it gives a larger shooting area. 2. Only turn the filter clockwise when viewing it from behind the camera to avoid repeating my mistake and lock the filter in place. 3. Carry a suitable filter wrench when using one of these filters just in case it gets stuck. 4. If it fits a P900 and it gets stuck. Zoom the lens so it points out about 30mm then remove the battery without turning the camera off. This will stop the lens retracting when the camera is off and if the camera is left on it will stop the lens trying to counteract the movement. 5. The lens and cap are stored in a small cellophane sleeve inside the plastic case. It is best to leave the lens cap on and insert it so that the flap of the cover is on the same side as the lens cap. This virtually eliminates the risk of the sticky flap touching the exposed filter surface. The only thing that would make this filter better is some sort of cover for the exposed surface or attachment points to hold the filter in place inside the case.

I have a Nikon camera; I like taking pictures... But sometimes I lose a lens cap. These 77mm caps fit my lenses perfectly. They sure cling. I've lost a few caps in the past because I took them off at the wrong time, but as a photojournalist, I'm busy walking around and getting into the right position for a good shot. I don't always keep an eye on my lens caps. These seem to have the filter well under control. The cleaning cloths are very fine and should help to keep the glasses clean. I haven't been a huge fan of lens cap lanyards in the past as they just seem to get in the way, but I might try one to see if these are any better than the ones that I used a few years ago. The price is great and the quality is there so they're a good buy for a professional or casual photographer.

The lens is securely attached to the adapter ring and this is precisely and stably inserted into the camera body. The Nikon Nikkor lens is on a Nikon Z camera. The adapter is well made and has an opaque interior to prevent reflections. I'm giving it 3 stars for value for money, not because it's obviously bad, but because it costs more than other mount/camera body combos. The whole thing deserves 5 stars because it works very well.

This adapter adapts my Nikkor lenses to my Fuji body (X-T1). It works perfectly and looks very good too. Like the flat black and silver rim. The silver ring in the center is for aperture control, so it also works for Nikon G lenses without an aperture ring and allows you to manually control the aperture of your Fuji. My copy is a little tight on the Nikon receiving end but works very well. And since I've had a few that were too loose, I don't mind. The aperture ring is 6-7 clicks so is better than the Fotiodix version I have which is only 3-4. Not much more to say but that it works well and allows me to use all my Nikon lenses on a Fuji body. Of course, this is all manual control, not autofocus or exposure control — just a metal tube that lets you mount Nikon lenses. At this price it's a great deal and works beautifully. It wasn't available for Prime when I got it and it took me about 2 weeks to get it.

This is model K&F M18111, Adapter for Nikon DX lens on Fuji XT-3 body. High quality processing; easily adapts to the body, snaps securely and without any noticeable movement. The same goes for adopting the Nikon lens. Cosmetically it could be a bit better, but that's not a problem - just the surface. Overall it works as advertised, no problem here. For the $30 adapter price, I suddenly have a whole bunch of DX Prime lenses that would otherwise have gone unused since switching to the Fuji X camera. The same could apply to you. As an aside, and that's just for the manufacturer, because you really can't ask for more for the price: it would be great to have a plastic cap on the camera end of the adapter: that way, if the user predominantly uses one lens, they wouldn't have to each Disassemble two components when he changes lenses. However, this does not affect the advertised functionality. Note: When operating, remember to select "Shoot without lens" in the Fuji setup menu.

This adapter ring is excellent quality (all metal) for the asking price. The processing is very good with very well calibrated processing in the lens mounts; Absolutely no problems with mounting, I even have to say that the first mounting of my Sigma 18-35 f1.8 (Nikon mount) on my Fuji XT2 was extremely hard, then in subsequent uses everything goes back to normal! However, you must be careful that the mounting direction of the ring on the lens side (Nikon mount hence) rotates in the opposite direction to the Fuji mount on the other side, and because of the relative strength of the mount you must be careful to rotate the ring to hold yourself tightly so as not to force the click to lock the bracket on the Fuji body, because by mounting the Nikon lens on the ring already on the body (that is, the opposite direction On the Fuji system) we press on the Mount the body in the direction the ring will be removed so press the safety button to lock the lenses in place AND NOT ON THE END OF THE BODY MOUNT STOP where it wouldn't matter. So be careful not to foolishly damage your body through mishandling... Otherwise, the Micro-Nikkor AF-D 60mm lenses and the Sigma 10-20mm f3.5 and 18-35mm f1.8 work very well on the Fuji XT2. Also note that while the diaphragm adjustment ring on the K&F is precise, the notches in the 6 positions are very (too much?) close together. Also, the apertures obtained are random or rather unknown (so not 2.8 to the exact 4 — we use an X-aperture, which is also different for each lens, albeit reproducible each time). A habit to get used to!
