F350 funny goings on with exposure?
I've got a Sony F350 on loan from Sony UK, but am experiencing a little problem with the exposure.
Shooting in 25p with the shutter switched manually to 50 I find that if I use the 'auto' button on the lens (switch set to M) temporarily to get a rough guesstimate of the exposure from the camera, it appears to be underexposing by nearly 2-Stops.
This is how I usually work, then once I have the cameras estimate I tweak it accordingly using the Zebras to guide me further. However, with the camera underexposing by 2 stops like this, it is a feature that might as well not exist as it is so far out in the underexposed department.
I had heard that this was a software issue in the early XDCAM HD cameras, but this one has just dropped off the production line.
I can't even use the iris under/over override as it can only be set to +1 F stop, I need to be able to set it to +2 to compensate for this irritation.
I know if I switch off the shutter the problem goes away, but then I'm introduced to images that are not quite as clear as when shutter is switched in to 50 manually.
Is this an annoying feature with XDCAM HD F350's or is their some sort of firmware that can be downloaded that I can do myself; or is it a back to Sony job?
