hi there brian. any comment on the focusing speed of the adapter with the latest firmware? thanks.
Metabones says the update improves focus speed and accuracy. Often these seems are hard to quantify by percentages more precise than it “seems faster.”
Hi Brian,
Can Sigma 150-600mm DG OS HSM 5-6.3F works on Metabones IV with Sony a7s?
I assume you mean the Canon EF mount. Yes they are compatible though I haven’t tested AF on that combination.
