PZ 16-35mm f4 unable to touch focus at 35mm

[Tom Garton]

Hello everyone,

Thank you in advance for any suggestions offered. New to the Sony ecosystem (from Fuji, very much enjoying the change so far) and I feel my issue is probably rather simple I just don't know the correct terminology to find the solution. 

Problem:

When zoomed in to 35mm on the PZ 16-35mm f4 I lose the ability to touch focus when recording video. I am recording 4k/30fps 100m on an a7c. At 34mm no problem. As soon as I get to 35mm a white box and magnifying symbol appear and it seems there is some sort of additional magnification range activated which disables touch focus. I thought it might be something to do with the APC mode setting but this is turned off. I don't want this extra magnification or to lose touch focus at 35mm. I am sure this is a very simple setting that experienced Sony shooters will know about and I am probably looking at it without knowing the name for it. 

Can anyone advise on what this is and how I might be able to turn it off? Thank you in advance.

Don't have an A7c so can't reproduce your issue, but try disabling clear image zoom / digital zoom:
