Fotasy Pentax PK K-Mount Lens to Micro Four Thirds M43 MFT System Camera Mount Adapter

This manual focus adapter (no electronics) fits and works perfectly with Nikon F-mount lenses with aperture ring on lens body. They may not serve some professional requirements like AE communication or lens profile, otherwise works fine. Such adapters are safer in general as far as danger of corrupting camera software is concerned (although OM system or Panasonic Lumix are much more robust than, say Canon).

Perfect fit, sturdy, fantastically smooth. Full value for money.👍

Works well, as intended. Using on the lumix g7

Using it on manual 50 MM lens with BMPCC 4K. no problem. working like a charm. Had a slight issue initially on how to unmount initially. There is a screw move it back and then rotate the adapter.

Good solution 👍

I ordered 2 quantity of this product this month, I installed it on my BMD mft mount and it didn't work at all. It's all blurred, did not work at all. Moreover, seller sent only one from the two I ordered. DON'T ORDER THIS if you have similar needs.

Excellent fitting. Good construction. Value for money. Now I can use my old Nikkor lenses with my LumixDmc gx85.

The adaptor quality is good , but as mentioned it is working only with canon EF-S(crop lens) but it is not working on Canon EF lens. I tried to call Amazon it seems no human contact but only computerized voice . I could not able to tell my problem. In app only replace option available not refund. I returned the adaptor let me get the replacement if it is also doesn't work I may have to see what are the options available.

Lo que esperaba, fotasy tiene muy buen equipo y da buenos resultados.

Fine

10/10 buenisimo para la G7 y lo digo yo porque nadie más lo dijo en las reviews y se siente bien feo comprar sin saber

Have not had opportunity to use it yet - Fits well mechanically.

Bought to use between Olympus EM1 and a non-digi Zeiss 70-210mm f4.5-5.6 with trombone zoom and full manual focus. Also planned for Helios etc. At any part of the zoom range, and from minimum to infinity, the helical gives some extra fine focus tuning. Set at close focus and max zoom, the lens aquires extra close focus, as the helical range of 35mm is the equivalent of a macro extension tube. Expect minor loss of light. I observed some sideloading on the helical when used horizontally with the hefty Zeiss, and avoided this by pointing the camera down while winding in or out, then raising it for live view fine adjustment. From birds on a wire to a close shot of a blackberry, this offers a walk-around kit of useful versatility, and sharpness that depends solely on the hand and eye of the user. The markings on this lens aligned perfectly with the camera, and does not rotate when the helical is wound out. The samples were taken within about 15 minutes, without changing any attachments. Well satisfied.
