I've decided to jump into the world of vintage lenses and recently purchased a Helios-44-2 2/58 Jupiter M42 lens on eBay.
Now I need to find an adapter to make it fit my Canon EOS R6. As far as I understand, the adapter doesn't do anything except convert one mount to another, so a cheap adapter should work just as well as a more expensive one, right?
Looking at Amazon, I've found a few different M42 adapters. What confuses me is that some of them seem to be thicker than others. Ideally, I would like to go with the smallest adapter I can find.
I hope it's OK to link to Amazon. Here are two examples:
M42 Screw Mount Lens Adapter Manual To Canon RF Lens for Canon EOS RP, EOS R Camera (£8)
K&F Concept M42 to EOS R Lens Mount Adapter for M42 Mount Lens and Compatible with Canon EOS R Cameras (£43)
Why wouldn't I go with the cheaper and smaller option?
EDIT: I found another small/cheap adapter and noticed one of the reviews stating that it didn't work with the Helios due to flange distance:

I used this to connect a Helios 44-2 lens to the can eos r. Wouldn’t allow me to focus at all. I think it leaves the lens too close to the sensor to focus properly. Not sure what this is actually useful for.
