Lets do some quick focus tests of the fantastic Tamron 150 - 600 G2 on the Sony A7R3 with the LA EA4. Note this is not my first choice of adapter and I will explain why in the video. This video is simply to show that it works, and quite well. I will show you image samples of this camera/lens combination and then do a sensor size comparison of the full frame Sony a99 and the Sony A7R3 because I was asked to do so. Thanks for watching everyone!
