Re: Sony A7rii + Sigma MC-11 + Sigma 85 1.4 ART Aperture Noise

Hi all,

Need advise from all experienced user with a7r2 + sigma 85mm 1.4 art.

With these gear im using adapter metabones mark V (FW 0.57). With these adapter on this lens does not meet my expectation. Result in a lot of hunting.

Is MC-11 perform fast focus like native do?

Additional info:

Metabones mark V on my Sigma 50mm 1.4 Art is working perfectly with fast focusing speed.
