In this weeks video I finally solve the focusing issue I had with my Sony A6400 paired to a canon mount Tamron 150-600 G2. I had my suspicions that the Sigma MC-11 adaptor may be to blame and with this in mind I tried the combination out with a Metabones Mk IV adaptor. In this video I explain how I have found this setup works and any issues I have noticed with it. I also show you some of the images I have produced with this setup over a very limited time. I am very happy with the combination so far and can recommend it as a good lightweight wildlife setup.
