Works well, snug fit with K mount.

If you use a genuine K-m42 mount adapter, it’s a lot harder to retrieve them off a K mount body. Other than that, solid cheap buy

Great lens adapter, bad light leak

Reviewed in the United States on August 25, 2023

I love the feel and visual aesthetic of these adapters, I got an m42 - E and a C/Y - E but both seem to have strong light leak where the lens attaches to the adapter.

However for the price this is still a fancy deal just expect light leak. Even the expensive lens adapters have some light leak.

So far I've used this to adapt two older A mount Minolta lenses on my E mount Sony a7ii camera. Everything works as advertised. This allows for manually setting the aperture for the lens. Other, cheaper products won't necessarily allow the aperture to be changed.

Sadly, this adapter has zero electronics. So for example it is unable to provide information about the lens or the aperture or the zoom level to the camera which would otherwise be embedded in the image files as exif data.

Another thing to keep in mind is that unlike with an e-mount lens, when you start adjusting the focus you will not get the automatic zoom in to assist with the focus process. Instead, you'll need to configure one of the buttons on the camera to zoom in for you.

The only adapter that allow for complete control of autofocus, and pass through of meta information for the exif data, are the expenses first party adapters by Sony. But of course you're looking at this adapter because it's 1/5 of the price.

It works, and fits tight.

Not much to say, it's a pretty simple adapter, but even that could potentially be screwed up by bad fits or not locking on properly, but this one is great. It's actually a tiny bit tight the first time you mount it, but better that than loose and have a light leak. It smoothed out after a coule of more uses. Good adapter.

May be the best $36 I've ever spent on camera gear

I recently upgraded my camera kit from my old A-mount Sony/Minolta gear to a Sony A7iii. Sony makes A-mount/E-mount adapters, but they cost hundreds of dollars, and most of them don't do autofocus with the A7iii.

The K&F Concept adapter is only $36, almost two hundred dollars cheaper than the Sony LA-EA5, which doesn't do autofocus with my A7iii, either. I have to set aperture manually with a ring on the adapter, but for nearly $200, I can live with that.

The two main lenses I wanted to use with my A7iii were my Tamron 90mm f/2.8 macro lens and my Tamron 70-210mm f/2.8 tele zoom. Replacing them with equivalent E-mount lenses would have run between $2200 and $3100, depending on the replacement lenses I chose. I'll have to set aperture and focus manually, but the A7iiI has good focusing aids. I do mostly landscape/cityscape photography, so manual focus isn't a deal breaker, and even the best autofocus isn't reliable at macro distances. For $2200, I can live with that.

The aperture ring is not marked, but there are eight very faint detents witch you can feel as you turn the ring. I generally shoot either at max aperture for limited depth of field, middle aperture, for best picture quality, and occasionally, stopped all the way down for maximum depth of field, so precise f stop numbers aren't a deal breaker.

If you have an E-mount camera and some old A-mount glass, you really should give this adapter a look.

Amazing quality

Reviewed in the United States on December 17, 2021

Size: MAF-EVerified Purchase

Compared with adapters that cost me 1/3 of the price, this is much higher quality, looks better, and rotates better. It has a slight smell of oil, though. Note that Amazon asks to grade 'auto focus' and 'image stabilization' - both are not applicable as this adapter has no electronic connectors.

I recently got a new Sony Full Frame camera which is takes E mount lenes. Sadly I only have C mount lenes so until I can purchase full frame lenes this adapter works great. There is no connections so it's a fulll in manual focus mode but it works and the price was right.

It would be a great adapter if it wasn’t for the fact that there is a light leak. Not terrible but it just shouldn’t happen. Maybe a defect.

Way too tight ..

The adapter is way too tight from both sides, I was actually afraid it’ll break the camera mount, I am not sure what’s the way forward ..
