Instructions for use Attention:
Attention:
Manual adapter without autofocus or aperture ring.
Skillful installation, don't too much force.
Adapting an APS-frame lens to a full-frame camera may generate vignetting, some cameras could correct it by adjusting APSC.
Adapting a full-frame lens to an APS-frame camera provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle.
And it will magnify the focal length by 1.6 on Canon, 1.5 on Nikon and Sony, 2.0 on M4/3 camera
Infinity focus position:
The position of the infinity mark [∞] of the telephoto lens is shifted slightly to the positive side to enable focus adjustment even when focus shift is caused due to temperature changes.

Well made and well packaged product
The ring is very well made. Used with Fuji XT-10+ M39 Canon lenses. Shooting without a lens must be enabled in the settings. The initial ratio of the lenses is distorted. Will be very interesting for landscape or still portraits. Infinity Focus seems to be working! You can see two photos taken with it! All you have to do is experiment :)

I love using this adapter for Canon Lens
I really like this additional tool for my Fujifilm cameras. It's a wonderful adapter. The photo I sent with this test is of the K&F Concept Lens Mount Adapter used with a Canon 100mm f2.8 macro lens. As you can see, the results are fantastic! Hope that helps :-)

Works as intended, no problems
The adapter does what it says 0 problems...
On arrival the m42 mount was misaligned but this is easily remedied by loosening the 4 screws on the side and turning into position.
But even if you don't, the adapter will work just fine.

Pleased
Good for the money. There‘s a tiny bit of play in it but doesn't affect the focus.

Good quality at good price
Bought this to fit old Pentax lenses to my Fujifilm X-T3. All good!

Works well, very good value for money
Decent adapter. Allows me to use all my old scallop Nikkors on my X-Pro2. Also allows me to use gelded AF Nikkors because the adapter has its own aperture ring. Arrived quickly and was very cheap for what it does. I‘d definitely recommend it.

Perfect for x mount

FAQs

No, not a transmission of any kind. This is a purely mechanical adapter with no electronic contacts.

No, no focal length or aperture change. Works absolutely like the Canon original that I use.

Don’t forget that it’s a manual lens adapter. Works with full manual lenses. If your lens has no physical aperture ring, you cannot control it from your camera

No Allen wrench comes with the unit and I did not need one. Mine did not require any adjustments and fit like a glove.
