Agree with you Bob that the overall quality of the K&F concept adapters is quite ok out of the box for the given price.
Though if you're pedantic than also these K&F concept adapters need some tweaking + modifications

The exact flange focal distance, like with many other generic third party adapters, is not given 100%. The tubes are slightly shorter too and hence infinity focus is not perfectly matching with the marking of the adapted lens. It's not that much on these K&F concept adapters, like I've seen with other cheap adapters where often infinity focus is reached with the lens set to 3-5m already. But to have the perfect flange focal distance, some levelling shim need to placed under the mount faced plate and "infinity being infinity" finally again.

Then also the black-anodized inner tube of these adapters is rather reflective and a modification to coat the inner side with a light absorbing self-adhesive foil to improve possible light reflections is advisable.

After all these modifications I'm happily using my "basic" K&F concept adapters for OM-NEX as well as the LM-NEX and haven't really seen the need for "premium" adapters, e.g. from Novoflex.

BTW, both "basic" K&F concept adapters for "OM-NEX" as well as the "LM-NEX" have four screws on the front mount.

E-mount adapters:

LA-EA1
My experience with the LA-EA1 on the Nex6 is that AF is totally unuseable on all SAM lenses period. But I'm quite happy with MF much of the time anyway, so I use the LA-EA1 with any of the dinky Sony easy-chocie primes (35/50/85mm) and they're just fine.

LA-EA2
The LA-EA2 gives good AF on the Nex 6 with any of the Minolta/Sony lenses I've tried but I've mostly acquired native E-mount alternatives now so it doesn't get a lot of use - maybe because it's bigger and sticks out too much for my small gadget bag, or maybe because I'm trending back to MF to improve my fun/nostalgia quotient.

Pixco speed booster A to E-mount.
Rather disappointed in this. It fails to give the whole view of an FF lens on the Nex (though I guess it's not far off), and judging by the shutter-speed change, gives only 10% to 20% more exposure so barely perceptible as a speed booster. It's pretty heavy and doesn't give you any data or AF capability, so not recommended unless the near-FF angle of view from your A-mount lenses is enough by itself. Oh, and once fitted my copy is very reluctant to be rmeoved without extreme measures.

Dumb adapters.
Have a lot of these, mostly very cheap. the lightweight cast aluminium ones from China are pretty good.

Pentax adapters:
There was a range of very lightweight plastic MF primes made in late film days for the Pentax K mount (28mm f2.8, 50mm f2) which work very well on a dumb Px-E adapter. Despite being plastic and cheap, they are pretty good optically, especially on APS-C.

Adapters for mirror lenses:
Worth a mention that although most mirror lenses were made for DSLRs and need a long adapter for E-mount, the ones that focus close (like the Kenko 400mm) can work with a short adapter: If you get a flat M42-E-mount adapter (intended for telescopes, etc) it's about an inch shorter than the usual one and though you lose close focus, you can still get a decent MF range out of it.
Miranda F & Sensorex, Sony A7Rii, A58, Nex-6, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras ...

I bought this Pixco branded M42 to E-mount Helicoid adapter. It's adjustable from 27 to 59 mm.

Contrary to what it says in the ad it allows infinity focus with all my M42 lenses

Also I have not observed any vignetting on Full Frame (A7Rii) using a 50 and a 200 mm lens. More testing to follow but so far it seems an excellent adaptor with better performance than advertised.

I have several M42 to E helicoids and have been using them for years with no issues. No problem with infinity. I have also various other helicoids of shorter length which I have dedicated to lenses from rangefinders and even an oscillograph lens.

Apologies for not reading through all 15 pages, but it's anyone able to recommend a cheap and dumb canon EF (lens) to Sony FE (body) adaptor. I don't need any fancy electricals, it's for a fully manual Laowa lens. Just reading around the subject and issues with light leak and internal reflections. I want something solid that can practically live on the lens.

Advice greatly appreciated - never owned a non sony A or FE lens before!

i do not think it is that important. Maybe stay away from the really cheap Chinese stuff. That means, look into Kipon, K&F and the like. These will be simple, but more or less fine.

The electronic ones like the Sigma MC-11 will surely be better, but it might not be what you need. (FYI: Harrison Camera has a used MC-11)

The best thing about the Sigma MC-11 is that it seems to be the right thickness. All the other adapters are purposely made short which is fine for unit-focus primes, but causes optical problems with other lenses. I should measure my adapters thicknesses. The Metabones IV definitely seems off.

The cheapest EF adapter I have is the Yongnuo EF-E II. Yongnuo has been updating the firmware, and it is actually getting pretty good. It supports native emulation.

The dumb adapters all seem to be made from the same parts. I heard the actual metal manufacturer is named RJ.

I guess most decent steel ones come from the same manufacturer. Recent K&F adapters are made in aluminium, not steel.

Have you had steel ones? The only steel parts in the adapters I've had were the screws.

What material are they when they are not steel? The mounts for sure are not aluminium.

Thanks Addy, picked up a K&F one which seems to be a new edition claiming it has reduced internal reflections. Will find out later this week when it arrives- and hopefully the lens too!

I believe most mounts are coated brass like keys. None of them are magnetic.

My Minolta 28-135 is taken apart right now, and its mount is definitely brass. There is a machined ring on the backside that shows the base material.

So, the adapters are brass? Like a Leica

You were lucky.
The first M42-MFT helicoid I brought SHOULD have just managed infinity focus from the quoted length range, but the listing didn't specifically claim it could. On arrival I found it couldn't reach infinity with a 135mm lens let alone shorter ones which see the effect of extension more.

On all subsequent helicoid purchases I've ensured the add quotes infinity focus if that's the way their likely to be used. The extra cost for this has been negligible.
