Cheap but half decent M42 adapters, any sources?

[fatdeeman]

Hi, guys!

Long time no see!

I've been getting back into photography a bit recently, and obviously that includes mf lenses!

Just a quick enquiry regarding m42 - Canon eos adapters.

A few years ago, when I was still quite active in the hobby, I just used to buy the cheapest adapters I could find on ebay/aliexpress, and they were usually fine for my use, and cheap enough that I could just buy one for each lens to save having to take adapters on and off.

But I recently tried buying some from a few different vendors and it seems like at some point over the years, the tooling has somehow been messed up so that the lens markings are always off centre, usually by 90 degrees or more!

I guess they haven't realised, or simply don't care, that they are pumping out 0000s of adapters with the thread not in the correct alignment of the markings to be in the correct place. Obviously it doesn't affect the functionality of the lenses, but it's really annoying!

It's also annoying because I used to be able to buy in bulk and pay about 50p each, and I'm a cheapskate!

So anyway, long story short, does anyone know any other cheap options which actually have the thread in the correct orientation?

I recently tried some of these adjustable ones which worked out about £2.50 each. Pretty nice quality and the adjustability takes care of the lens marking issue.

Only problem is the last two times I've tried to order some, the sellers have said they have had a bad batch and can't send them out

I also ordered some of these, as they seem a little bit better quality than the cheapo ones, so I'm hoping they have the screw thread in the correct orientation. The black version without chip can be had for around £1.90

Anyone know of any other cheap but decent options? Or a source for the bog standard ones but with the thread machined correctly?

I'm personally not bothered by the lenses not being aligned right, though I suppose there will be lenses with rectangular baffles where it might matter (at least on FF).

I have quite a wide variety of M42 adapters to different mounts, but EF is the most common (even though I don't have an EF body). Only one of my adapters is adjustable for lens rotation.

FWIW I have noticed the prices rising steadily (and cheap ones doubling on brexit) and Chinese e-bay several suppliers now refuse to sell to me but I can't guess why (no bad feedback left & returns wanted).

I have a bunch of adjustable M42-EOS adapters and a few chips you can have for shipping. I'll dig them out tomorrow...
