In Topic: Sony Alpha 7S for video - ???

I heard on one review that manual white balance was not possible while doing video with the A7S - if that's true I think it would be a deal breaker..

Peter - or anyone that has the zoom gear for the 14-42PZ - can the zoom gear be adjusted to operate the focus switch instead of the zoom switch? If that is the case then the zoom can be accomplished via the menu dial (after assigning the zoom control to a function button).

As I understand it, you can't do manual focus with the Olympus 12-50mm. I'm pretty sure I would miss that when shooting macro. Can you do manual focus with the Panasonic 14-42mm?

 

 That's correct - not on the Nauticam 12-50mm port. (not sure if a mf option exists). I don't believe focus is an option on the 14-42 either.

Ambient light in a cave or wreck? Who does that? If you are even moderately deep and using ambient light you are going to be at ISO 3200+ (depending on how fast your lens is) and going to definitely have significant noise if you are lifting the shadows. Will be interesting to see how the A7S performs in these kinds of environments.

 

The tests I've done on land with the GH4 in low light has produced much better results then the GH2 at ISO 1600 lifting the shadows by about 50 in Premiere. Even at 3200 the noise has been tolerable and hasn't required any removal. Haven't done any low light underwater testing yet - hopefully soon..

I have the 12-50mm and it is overall a great lens for video. The pro's are the electronic zoom and great range (12mm to 43mm macro mode/50mm zoom). The big con is definitely have no OIS. Why can't camera manufacturers understand our needs??? I have the 14-42 PZ (or should I say, my wife does on her EM10). I'd be interested in trying it underwater. If I can get similar results using my subsee +10 and the OIS improves the non-tripod mounted U/W shots, I'd consider making the switch.

 

I believe also with the GH4 you can use the thumb control to control the electronic zoom? I haven't tried this yet, but read about it this week. (I have used the electronic zoom controls on the Wi-fi app which work great).
