These are great for their price. There is some play in the fit, but this is along the circular path and does not affect the focus of the image in any way. Very cost-effective solution for mounting waste glass on the E-mount housings.

I bought it to attach M42 mount to Sony E mount. Basically, most lenses are old, so I think there may be individual differences with each lens, but the aperture and focus rings will be difficult to use when they arrive. It is necessary to loosen the screw and shift the bracket on the M42 side.

Autofocus is not supported, but you can use Canon lenses with the Sony αIII. As autofocus is not supported, only manual focus can be used, but this is saved as it has been moved by Canon. I don't use autofocus very often when shooting movies, so I figured this would be enough if I wanted to lock focus. I also have a SIGMA product, but if you don't use autofocus, this light product is an ant.

I think the accuracy of the product is good with no rattling. I was able to attach a lens for Sony with no problems. Lenses are expensive so an adapter like this would be helpful.

I use it for video recording with an adapter that converts an EF/EF-S lens to an E-mount to attach to Sony's α6600. Since there is no electronic contact point, I use a basic manual focus or cinema lens, but any lens that can change focus manually can be used as is. Due to the black matte treatment inside, there are hardly any irregular reflections and hardly any effects on videos and pictures. The EF-S lens was difficult to insert when attached and I felt the fixation was a little rough. I had no problems with cinema lenses or manual focus EF mount lenses.

Ring Used to adapt a Tamron 70-200 F/2.8 in A-mount to my A7s in E-mount Quite hard enough to connect on the lens side and soft on the A7s side (it's better than the other way around.. .) the membrane ring is easy to handle. The infinity is preserved. The price remains fairly steep, but the build quality is visible and the results are there: no play on either side of the ring.

recently bought this to use my Canon lenses on my Sony a6300. I bought it mainly to use my 50mm on it but it doesn't work. This is because the 50mm lens has an electronic motorized focusing system, which means it cannot be found through the adapter. However, I tried my 14mm Samyang and it works perfectly. Manual focus works as it should, as does my 75-300mm zoom lens, which also works perfectly. I think it just has something to do with the electronics of some lenses so be careful before you buy, just a warning! Otherwise very happy with the product, sturdy, metal and no play in the lens contact.

Does what I expected. I just bought my first full frame Sony A7. My last camera was a now very old Canon 350d. At the moment I can't afford to buy a lease that covers that 200mm range so I have to use my old Tamron lens. Manual focus and no aperture control, but seems to work with the peaking feature. But for the price it does what I need.

Bought to use old manual M42 lenses adapted to EF on my Sony A7iii. The K&F Concept EF to Nex adapter works perfectly. It has a nice tight connection to the camera body and all my EF fitted lenses fit very well. Lenses focus as they should. Worth £25 to be able to use vintage lenses on a digital body.

Read the reviews for the previous iteration and they were mixed. I went for it because I knew I could return it, but I won't. Haven't used it with the sun near the field of view yet so can't say if the matte interior reduces flare. Feels good and at this price I can buy one for every lens I need.
