ISO rating

Between John Beale and Victor Kong, we've come up with an ASA/ISO equivalent of around 150 for the TRV 900; has anyone determined the rating for the VX 2000?

I have no way of verifying, but if I had to guess using your findings, I'd say it's 250-400, or about one f/stop better.

Time for you to shoot a gray card, full frame, @ 0, +.25, +.5, -.25, -.5 ,etc., note the f/stop and shutter settings and play them back.

Realistically, just shoot the card full frame on auto, and read the settings of the data code. Make sure not to be in low light, so gain isn't part of this test (do that later, in the same manner).

Then align your f/stop and shutter speed as an EV (exposure value) and see what ISO translates.

Then compare playback to see if the zero setting shows a gray card to be just that, middle gray. If not, then which one is? +.25?, -.5? If +.5 is right to you, then again, align your f/stop and shutter speed as an EV (exposure value) and see what ISO translates.

Unless you're using some tech equip, this is going to be subjective, as your tv, and or vcr link (in the middle) will vary from maker to maker or even personal preferences in your tv setup.

I know, I know, we should all be running color bars on our tvs.

The industry rates things @2000 lux. My xl1s just spec'd at f/8 [I'm sure @1/60th] @2,000 lux. That was by a tech, not Canon's rating. I think this is about a half to one stop less sensitive than a VX/PD.
