A7S judders in continuous auto focus mode (AF-C)
Sep 2, 2014

Hi all

Bought my A7s on friday and have just noticed any issue when using continuous auto focus (AF-C) when I do half press of the shutter to lock and track focus the lens judders in and out for a few seconds and then will settle. Whenever I move the lens judders in and out again. Happens in all the 'focus area' modes (centre, zone, wide etc). Happens with all my sony/zeiss lenses (55, 35 and to a lesser degree with the 24-70)

I have the A7 which doesn't do this but will lock (when it wants too) and doesn't judder in and out. I am wondering anyone with S can try this out to see what happens. Unfortunately my dealer has none available at the moment to test against
