HV20 Low light performance? - Techwatch: Satellite TV forums, FTA, Cable, Hardware, & Tech forums

Is the low light performance of the HV20 any better than the HV10? Thanks.

It definitely is. The spec says HV10, 5lux for HV10 and 3lux for HV20.

Waiting to see some lowlight clips though.

Canon says the lowlight performance has been improved over hv10, so...

The chip is the same, so the camcorder probably use blur effect to reduce blue noise. Maybe the final result is acceptable...

I heard the HV-20 uses the same sensor as the HV 10. How are they able to lower the lux down to 3lux? With a Better faster lense? In camcorder software noise reduction? I think I read they are getting the better low light by a slower shutter?

I'm curious about this as well. I'd love to see some comparison reviews, and I'll look at the footage here.

Would the size of the lense have anything to do with it?

Probably a faster lense. Slower shutter would do it but will affect the motion giving more blur. I have to believe it's a faster lense.

That minimum illuminance rating might be simply the result of 24p at 1/48th sec shutter vs 30p at 1/60th shutter. Normally the illuminance rating is followed by gain lens and shutter details (ie. +18db f1.6 1/60th) but since this is a consumer camera, they could be doing anything, like counting a super slow shutter mode that wouldnt actually be usable except as novelty. the lens is still f1.8 so its not the lens. anyone see any details about the lux rating?

Is anyone aware of any low light clips that are available for download?
