I'm a couple of days into an LB indie-feature shooting on Sony F55 with Angenieux zooms. With budget and time constraints we never had a chance to properly test the camera, and I now have a couple of questions perhaps someone enlightened might help me out with?
I find that on native ISO (1250) the camera need 1 to 2 stops more light then what my light reader says. We are shooting in SR Codec so the picture I'm looking at is flat profile, and when shooting in SR it appears there is no way to get a Rec709 preview in the EVF/Monitor. At first I thought this was what was throwing me of, but even after the DIT applied a LUT it still feels like the camera does need at least one more stop of light the I'd expect on ISO 1250. Has anyone else had this experience? Has anyone done any tests under more controlled circumstances?
The exposure assist in camera is terrible, there is the waveform which is fine, but that's the waveform before LUT is applied so it's not telling me what my luminance will be in the final picture. There's no false colour etc. only zebra which says very little about the information in the picture.
Using the waveform at least I know I'm not crushing blacks or clipping whites, but I feel like I don't have the same control over exposure as I have on film, Alexa, Red or even on my magic lantern'ed 5D!
The picture looks great though. And I must say that the low light capabilities are great, and the low weight appreciated. Though when fully kited up it becomes a very long camera.
I'm also looking for a good comparison between SR codec to XAVC. The "low" bitrate of XAVC scares me a bit, but it seems to be a very sophisticated codec. Does anyone know how it holds up in grade? And how it holds up for keying?
I will try to find the time to do some more controlled tests to post here for everyone. In the meantime I'm rating my light meter to +1 stop for F55.
