I realize you've said the Chinese
adapters are claimed to be made
for SLRs. Maybe true maybe not.
Even if true, the original version
is a weird contraption and I really
doubt that a cheap knock-off can
ever be trustworthy. If the knock
of is non-coupled, just a mount
flange adapter for totally manual
operation, then I'd trust it.
I use a Chinese adapter, made for
use on live view cameras, not for
SLRs. It does away with all of that
Rube Goldbergery. Just leave one
adapter on the body and you now
have a "Tamron Mount" camera.
The Tamron lenses,
without any
Adaptal-2 devices attached, can
be swapped quickly and securely.
If the Chinese knock-off is as dirt
simple as what I use, but has the
proper flange distance for an SLR,
and you're good with fully manual
operation, should be an OK option.
