Its snug on my Em10 mark 1 and Em5 Mark 2 with no wobble. Is threaded so that lens markings are on the top (which for some reason many adapters don't do???), and allows lenses to focus to infinity. I would also suggest buying another M4/3 back cap for the adapter so that it can just stay on your lens without dust getting into it.

Great adapter. I had an old Pentax 42mm screw end. This kit worked perfectly to fit it on my new Olympus pen epl7· It looks well built and solid. very happy looks solid. Maybe they could have included some screws to secure the lens.

I have a bunch of K&F adapters & they've all been wonderful. They feel sturdy, fit snugly, & damn if they don't make my life a helluva lot easier what with all the camera/lens combos I can get with their help. & so derned affordable!

Everything works fine ! No lag and aperture settings in correct position for m42 lens.

Works well, and feels solid and well made. All lines up as it should on the mount, and focuses to infinity (possibly slightly beyond; I may tweak this a little). One thing to note is that there's no stop-down button, just a fixed ring to hold the pin in, so you can't use the preset apreture on most lenses.

Very useful adapter that gives a new lease of life to decent lenses which are readily available from charity shops and online auction sites.

Was a little sceptical given how cheap this product was. However, the build quality is fantastic, feels good in the hand and doesn't feel cheap in the slightest. I can now attach vintage M42 lenses to my GH4 with ease.

I'm always impressed by the quality of every item I ordered from K&F Concept. Very carefully crafted from high quality materials and great looking too. Perfectly fits both lens and camera body.

Really good build quality. All metal construction and very durable. My Helios 44/2 M42 lens fits perfect using this adapter!
