There shouldn't be a problem, but I'm not absolutely certain. I think it has problems with the M5.

Short answer: YES.

(I had a SA21 before, ever used it wih M3 also. SA21 had been sold. can confirm that M3 can couple with SA21 down to 1m. after that, scale-focusing liao.)

When I measure the distance from camera to subject is 3 metre, my M3 couple with SA21 at 4 metre but with elmar50 at 3 metre? And the minium couple forcusing is 0.8 metre. Do anyone face this problem? Thanks.
