Upload & Sell: On
I was recently in the market for an affordable Canon FD adapter to evaluate an FD lens.
I've had good luck with K&F Concept adapters among the cheap ones.
Then I saw on eBay someone advertising a "Mark II" "all brass" K&F adapter.
I was skeptical, but it was the usual reasonable price so I ordered one.
Well it's arrived, and yes it is a step up in build from their usual (perfectly serviceable) ones.
Both the camera mount and the lens mount are very smooth chrome plated brass (unlike the older ones where it was just the lens mount). And the quality of the chrome seems better.
Also the inside is a better grade of very matte finish than they used to use. ; not the excellent baffles of Rayqual, or the OK millings of Novoflex, but better than most. And accuracy seems good, though I haven't used it on a wide.
Only downside is that it's a bit heavy, but that's reassuring.
I'd say the Mark II ones are far and away the best bargain adapters I've come across. You can pay a little less and get a lot less. You can pay a lot more and get a little more. I'd still go Rayqual or Novoflex (or Hawk's for Leica M) for a pricey lens that I expect not to keep for many years, but these are nice.
I'm not sure how many mounts the Mk !! version comes in
(one respect in which Novoflex is better for FD is that I like their aperture leave retentions system: the K&F has the ring you have to engage that many have, though it's better made than most)
One last thing: I think only one seller called them "new MkII copper (which seems to be uniform Chinese English for brass)" . But you can tell by the photo whether the camera mount is black or chromed. I can see both types for sale: in M42 mount the old one is being sold for twice the price of the new one!
