Certainly comfortable, functional, medium size (I put 2 Nikon SLRs, 3 lenses, a flash, 3 containers with filters and there is still some space left. There are also several pockets for memory cards, batteries, as well as the possibility of attaching a tripod. I haven't checked the water resistance at the moment. Bought on offer, excellent value for money

I bought the Nikkor MC 105 macro lens for my Nikon z5 camera. Since I always install an Immerdraauf protective filter straight away, I ordered the UV filter and K&F (I already know the brand from other products and have always been very satisfied). As expected, everything is great with this filter.

bought the adapter because I also want to use my existing Nikon lenses on the new BMPCC4K. Since the vast majority of lenses have an aperture lever, they can also be used although they do not have a separate aperture ring (lenses without an E-mark!). The adapter makes a very valuable impression. It is made of metal and feels good in the hand. It easily connects to the camera and lens. I haven't found any game so far. If this occurs during use and possibly leads to scattered light, I will provide an update. The adapter is delivered in a small plastic box. This makes it easy to store or transport when not in use. The silver ring is used to set the aperture. However, there are no numbers, only a symbol for an open and one for a closed aperture. But you can see directly on the display how turning the ring affects the brightness. So I don't miss numbers. In addition, I have read on other adapters with numbers on the ring that these values are not as finely graded as the numbers make it seem. I am very happy with this adapter. Of course, you lose light intensity because every assembly between the lens and the sensor "swallows" light. But this adapter only costs a fraction of what a Speed Booster costs. Also, you can't get a speed booster with contacts for Nikon lenses. No information is passed on to the camera, so you have to set everything manually even when using a speed booster. I can highly recommend this adapter to anyone who can get along with a somewhat lower light intensity.

Purchased to use Sigma 50mm macro, Nikon mount, on my XT3. After some uncertainty by pairing the adapter to the lens (instead it fits the camera body perfectly) I have to say that I am completely satisfied. The optics maintain good quality in both photos and videos. It also looks well built so I hope it lasts a long time.

As the manufacturer specifically states, this does not allow full use of M-mount lenses on your Nikon SLR — it is intended for macro photography only. If that's what you need, this adapter is perfect.

When I ditched my Nikon and switched to the Sony A7IV, I chose this adapter because of the amount of Nikon lenses I already had. Primarily for my Nikon macro lens, on which I focused manually most of the time anyway, it doesn't bother me at all that the adapter is manual. Money was clearly saved here by saving myself the Sony macro. The adapter sits well on the camera and lens, so it fits extremely well and looks sleek. A Nikon lens on a Sony body is always an eye-catcher. The aperture ring is of course also manual and does not tell the camera what aperture level you are at. In the metadata of the photos, it simply shows F--. So you have to develop a feeling for which aperture you have just set. I did notice a little more Cromatic abortion, but that can be quickly remedied in Lightroom by selecting the lens. Images are sharp and the adapter has no downsides other than adding some length to the lens.

So far I have had five different adapter rings for different system cameras from K&F, all of them mainly for taking portraits with Nikon lenses or doing macro photography (especially Tokina 100mm 2.8 with Nikon connection). All specimens have so far been manufactured very precisely and made and make a high-quality impression. Therefore full points, because the price-performance ratio of these items is really outstanding.

NIK-NIK Z-Ring single ring, without coupling: Nikon Z-mount male mount, Nikon F-mount mount female for pre-AI, AI and AIS lenses. You can therefore use old lenses whose pre-AI bayonet can damage the FTZ. No problem with a Nikon Z: the light is measured at the actual aperture and manual focusing is done with colored markings in the viewfinder. So I use my old 50mm 1.4, my 20mm 3.5 UD, my 300 4.5 Nikkor H which are all 50 years old... and my AI 50.135 and 200. The ring is well built, no play and we have infinity. NIK(G)-NIK Z-Ring Attention, for Nikon G lenses you need the Nikon FTZ or the NIK(G)-NIK Z-Ring, which allows you to maneuver the aperture, which do not have a ring on the lens. With the NIK-NIK Z, the G lens remains closed at the smallest aperture, so no modification is possible. Attention should also be paid to the IBIS: you need to record the focal length of the manual lens and specify it when using the camera: vibration compensation is much more effective if the Z camera knows the focal length.
