The adapter fits perfectly, nothing wobbles. The aperture setting works continuously, which is perfectly okay. Some disadvantage of the aperture ring is that it doesn't quite fit depending on the tripod (in this case the old big Bilora). The aperture ring sits close to the body and is larger towards the bottom than the camera body. With a normal sized tripod everything fits without any problems

already had rings to use Canon FD lenses on my Mirrorless Samsung NX30 but I wasn't entirely happy with them... on a friend's suggestion I wanted to try them and I have to say that from a constructive point of view they are really well done . No mechanical play, the lens is firmly attached to both the ring and the camera body and not even the stop-down ring of the apertures (which allows you to set the aperture to the desired value) remains locked in the selected position. We recommend!!! Top shipping service (as always)...!

The action on the variable ring is great. Smooth, stiff enough to stay in place but not so stiff as to unthread or overtighten to the lens. The optical quality is good to great with minimal internal reflection. At 500m / F11 / 1/250 s it's TOO dark for anything but a completely full moon. I'll probably use it more for full snow imaging than the intended purpose of lunar photography but I'll definitely use it.

It's amazing that the quality was so good for this price. Full metal, lockable aperture ring and flat support on camera and lens bayonet. Functional test with a Lumix G3 and Olympus Om-D 10 successful. This adapter deserves full marks.

This streak filter can be rotated up to 360 degrees and is perfect for creating differently angled and dynamically rotating flares. The anamorphic streak filter from K&F Concept creates a cinematic vintage effect on photos and videos by transforming points of light into linear anamorphic light reflections. It has a 77mm camera lens with a mounting thread. With an adapter ring, a step-up ring or a step-down ring, it can also be used for camera lenses from 32mm to 82mm. It is equipped with 8K Ultra HD optical glass, has 28 nano-layers and low reflectivity that ensures high-resolution photos and video recordings. It is lightweight and consists of an anodized aluminum alloy frame. It has an ultra-thin frame that reduces vignetting and dark corners when mounted on a wide-angle lens. CNC machined and anodized aluminum alloy frame is built to last, abrasion and erosion resistant. In addition, the trapezoidal pattern on the frame is ideal for easier grip and non-slip function. The filter is excellent because it is waterproof and oil resistant. I like the fact that the lenses can be rotated to adjust the angle of the spread. Also, the brightness and intensity of the filter will depend on your setup and the light you're shooting. The compact effect filter comes with a filter box and a cleaning cloth, making it efficient and practical for your recording and filming. All in all, this is a great product that allows me to be more creative in my photo shoots with less effort.

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.

With this adapter I can use all my Nikkor or Nikon lenses on the Fujifilm E-X1. However, it is necessary to set the “Shoot without a lens” option in the menu, otherwise the shutter button will not click. The diaphragm is closed by the intuitive ring. I tried it with a G Sigma EX 1 lens; 4-5.6 with 10-20mm focal points (equivalent to 15-30mm of a full frame): The ring allows you to close the aperture while maintaining full aperture for manual focus, from 24cm to infinity. Of course, the Fuji ring works better for Leitz M lenses, since it is enough to set "adapter" and focal length and any distortions can be corrected. But it costs more than ten times as much. Focus is obviously done manually as with digital and analogue Leica Ms. The courier was unable to deliver on the scheduled day, claiming that "no one was there". Instead we were all there. Saturday to Monday. Then don't complain if Amazon will use drones.

Bought in 2023, after a long time I feel like giving a review because it is the best lens of my kit. It has been used on Canon APS-C and now full frame Sony and has allowed me to take great shots home. Since it's wide-angle (so with a wide hyperfocal) you don't have to spend money to buy the autofocus version and the focus ring allows you to set focus very precisely and fluidly, but I'm sure that You will keep it in an infinite position 90% of the time. The other ring of the cone port is very useful and well made, with clicks that are easy to "hear". The sharpness is great, it loses slightly in the corners in full frame, but still remains excellent. Vignetting isn't a problem at all and closing the aperture at f/4 isn't as noticeable. I didn't notice any discrepancies in any of the many recordings. The aperture of f2.8 allows this lens to be used even in low light conditions or for those who want to take their first steps in the world of astrophotography. The downsides are minor and negligible: the outward weight distribution, the fixed lens hood, and the aperture ring partially covered by the built-in flash. I think this is the first lens to buy for those who want to "ditch" the kit. You will always carry it with you.
