K&F Concept Lens Mount Adapter Compatible with Leica M39 (39mm x1 Leica Thread Mount) Lens to Fujifilm X-Pro1 Mirrorless Camera

I did once order a lens adapter years ago when they were available but it was not tool right, and hoping that they would re tool the distance from film plane to the lens plane, as I received this it that first thing that I put on was my vintage 35mm 2.8 Sankyo 39mm LTM lens from my Canon, and place it on my Fuji XE1, and XPro1 as the images were very stronger with contrast, and colors, and the important is that this 60 year lens is that it is still holding the SHARPNESS Thank you.

Excellent quality for the price. Accurate focus and no wobble. K&F adapters are better than some that are much more expensive.

This is a well-made adapter.I've mounted various old Leica screw mount (M39/L39/LTM) lenses to my Fuji X-T3 camera and used them. Focus peaking works as long as camera is in manual mode. Got some great images with these old lenses, makes me wonder why I spent a fortune on modern AF versions!

Fits very smoothly to the camera mount, and allow the lens to be oriented "right way up" when screwed in.

Works great! Spot-on infinity focus. My lens (M-mount Voigtländer 15mm) did not precisely align with the center of the camera when fully screwed in, but the adapter has three hex bolts (pretty fine: 0.9mm) that can be loosened to perfectly align it. Works beautifully.

I recently purchased K&F Concept's M42-FX: they are great and work as expected.Based on this, I then bought three M39-FX by K&F Concept, and: one is so tight I can't even turn it far enough for it to "click" into the lens mount; one is tight enough that it takes a lot of muscle to get it to click; and one is tighter than I would like, but still usable.In terms of engineering and testing, manufacturing these adapters should be a no-brainer. Time to find another brand.

Buona qualità costruttiva, tutto in metallo, ben rifinito.Accoppiamento lato macchina (ho una Fujifilm X-E1) e lato obiettivi saldo e senza gioco.Lo utilizzo con vecchi obiettivi Leica (Elmar 90 e 135).Unico difetto: L'obiettivo Elmar 135 ha una flangia per l'attacco al cavalletto. Avvitando l'adattatore, la flangia risulta decisamente non allineata con la macchina. Tuttavia ho notato che la flangia filettata che accoglie l'obiettivo ha delle micro brugole e probabilmente è possibile ruotarla per ottenere il necessario allineamento.
