Question for you - can I hit the AF/MF button to disengage the AF feature, and then re-enable it, all during the same "take"? Meaning if I'm tracking a moving subject and know it's going to be in one spot for a while, and I want 0 chance of the camera trying to refocus on another target entering the frame, can I do that? Let's use lions walking around in a zoo for example. Or could I just use your aforementioned "manual" autofocus then?
Thanks for your help. I might even sell the 5d3 if this works out - I find myself rarely going about ISO 1600 and certainly could use more reach. The problem is ML raw has made the video so gorgeous it'd be so hard to not have that as an option. Plus winter's approaching (along with Halloween night; one of my favorite nights to shoot video) and I know I'll need the low light. Sigh. What to do.
I don't have a button on my lens, but on the bottom left of the touchscreen, the Servo AF button is available all the time while recording, so you can turn it on or off. If recording a longer session, you can turn it off when using manual autofocus and it won't automatically focus, and when you're done, you turn it back on, and continues servo autofocusing.
As for the ISO: it is an APS-C:) A videographer guy using 7D asked me to make a 100-12800 ISO noise test and he told that it's about 1 stop better than the 7D. It also has slightly better dynamic range. 70D also has ALL-I and IPB modes, if interested.
