Sony A77 when in movie mode & autofocus on, cant open aperture more than f/3.5
I purchased a Sony A77 mainly for the purpose of using it for taking videos because of its full-time autofocus (AF) capability, & other neat features, such as in-camera stabilizer (no need for expensive heavy IS lenses), variable setting peaking indicator that switches on automatically when AF is turned off, incredible sharp OLED VF & Monitor that stays in HD and doesnt drop to 480 SD quality while recording which is what I hate about my Canon 5DM2 when shooting video.
Anyway, I have 14 days to return it if it doesn't perform the way I like it.
My only complain so far right now is that when in movie mode, I cant seem to open the aperture greater than f/3.5 when AF is turned on and while recording. To shoot at f/2.8, you have to turn off AF (when using the kit lens of f/2.8 16-50mm) which essentially is switching it to manual mode. Why in the world can't they make AF independent of exposure settings? It doesnt matter if I had it on 60p 1940x1080, or 60i, or 24p, etc.
Any thoughts? Sony why?
