M42 to NEX Lens Mount Adapter, for M42 Screw Mount Lens and Compatible with Sony Alpha E-Mount Cameras

A very well made and very solid adapter which does the job perfectly.

Perfect for vintage manual m42 lenses on my Sony a5100, build quality is all metal so it is durable and can hold the absolute tanks that are old Russian lenses. Especially when the lens weighs 3x the weight of the body :')

Good quality item, fit perfectly

Works perfectly on the Sony Alpha A6000 as it should. This attachment allows you to use the old M42 screw lenses with the modern Sony E-Mount cameras however bear in mind the auto focus will no longer work while the lens is attached and you will have to use the focus ring on the lens itself. Ive used it in conjunction with a Carl Zeiss Tessar 50mm and it has produced some lovely sharp photos. For the price of this unit and a second hand lens you have a very nice set up for very little money

Works perfectly, great value for money considering how expensive these adapters can be

The quality of these adapters are unreal. This will be my second m42 adapter from K&F and both are exceptional quality, and accommodate the small aperture pin on these lenses. My only feedback would be ideally if the adapters were a bit lighter, especially as m42 lenses themself tend to be on the heavier side so the weight does become a little much but not enough for me to not use them by any means.

The adaptor itself seems to work fine. I've used it with lenses like the Helios 44M 58mm and Helios 28mm wide-angle with much success. However after shooting with it for several days, I've noticed maybe a dozen fine metal particles covering my A7ii's sensor. I can't be certain whether the particles came from a lens or the adaptor itself, but it might be a good idea to leave one of these adaptors on each M42 lens you have, or purchase a more expensive one that won't wear.

need an adapter for my sony a5000 and a set of carl zeiss lens, the K&F Concept M42 works wonders, pretty made up with everying thats important, does what it does, and pretty well.

L'anello si presenta tutto d'un pezzo, nessun comando di sblocco o altro, si avvita semplicemente l'ottica sull'adattatore ed il gioco è fatto. Io ci monto uno Zenit Helios 44-2 58mm f/2.0 e Meyer-Optik Görlitz Domiplan 50mm 2.8 senza alcun problema. Pregi: - è garantita la messa a fuoco all'infinito - si possono utilizzare i diaframmi. Generalmente con le ottiche M42, come per altre tipologie, si lavora in preset, ovvero si imposta il diaframma, si compone a tutta apertura e al momento dello scatto la fotocamera agisce su un comando che chiude al diaframma impostato. Con questo anello invece il comando rimane "premuto" ed il diaframma rimane impostato al valore impostato. Difetti: - un poco pesantuccio, circa 110gr che si fanno sentire ma fidatevi è realizzato con cura e qualità.

The quality of this lens adaptor is unbelievably good for the price, it looks and feel premium.

El mejor adaptador que conozco para lentes a rosca M42 a Sony (montura M42 a montura E) sin holguras y de calidad de construcción y ajuste perfectos.

Just got this K&F Concept adapter for my Sony FX30, and it's been awesome. Needed something to adapt my Helios 44-2, and this thing did the trick perfectly. No issues at all, it just worked. The build feels super sturdy. Doesn’t feel cheap or flimsy, which is great. I was kinda worried about attaching my Helios to the camera, but this adapter made it easy. It fits snugly and securely, so I'm not stressed about the lens wobbling or anything. Installing it was easy too. Just popped it on my camera and the lens, and voila, ready to go. It’s manual, but that's obvious since it's for old m42 glass So, if you're looking for a good adapter to use old lenses on your Sony, this K&F one is a great pick. Works flawlessly, feels solid, and it’s not too pricey. Definitely a good buy!

Does the job
