On the sony support website, it says that the firmware update 1.20 ....
" Provides support for the SEL70200G lens: - Supports the "Fast Hybrid AF" function and future Fast Hybrid AF compatible E mount lenses - Adds the "Focus hold button" function "
I had this lens in use on the A7 before the update and do not notice any change. I have even the impression that the autofocus is somewhat slower than before the update, but this may be subjectively ill-founded.
So - does anybody know, how this "Fast Hybrid AF" function now newly manifests itself (how did it work before ?) when one is using the SEL70200G and in which way the "Focus hold button" is now integrated in the camera software other than before ?
