From Sony HC1 to SR12?
Hi
I have almost the 3 years the sony HC1. Should i replace it with the SR12? I read that the SR12 may have better low light perfomance than the canon HV30, is that true? Should i see better image quality from SR12? thanks |

Well I had just about all the consumers HD cams including the HC1. To my eyes the SR12 produces a picture with lower noise, broader color palette and just about equal resolution.

Since the A1 has all the controls I want, I'm curious about the noise you mention. The SR11 is amazing as long as gain doesn't go above +12dB. But, +12dB is the limit for most Sony camcorders. Thus, do you have sense of how different the sensitivity is say in a room with a few hundred watts of light.

In terms of sensitivity, I never really lined up the cams to test for that specifically. I can tell you that in a room with a couple of hundred watts of light, there is very little noise in the SR12. Some cam manufacturers seem to ramp up the gain very quickly to produce a brighter image. The fact is that many of these cams produce a brighter image than your eyes actually see, but at the expense of noise. I've never seen the value in that. Give me a luminance value that more closely mimics the actual lighting conditions and throw in the resultant lower noise levels that result. The SR12 seems to do that better than most consumer HD cams. |

I shot my room with about 100W on a dimmer. Turning it down slowly I was blown away by the SR11's ability to simply get darker WITHOUT a significant increase in noise. In fact, on the LCD I saw NO noise even at the point were it was possible to see something my eyes couldn't see. Given I was looking at the LCD in complete darkness it was something I've never seen before.

Agreed. Manual control of gain would be a very very welcome feature. I haven't used the twilight mode in that manner. Do you find it alters the image in any other way other than limiting gain?

I've not explored any of the presets in the SR12. Is there a resource somewhere that details what the parameters are for each preset??
That would be very useful info since there is such limited manual control.

I'm rewriting the color balance chapter and I need to see what what Sony means by Twilite "focus at a distance." I measured it years ago, but need to do it again. I really don't know WHY they just don't have a simple gain limiter. JVC's AGC works nicely -- JVC determines the point where minimal noise shows up and limits max to that amount. (Why tie it to Twilight?) If you want max sensitivity you turn on Slow Shutter. PS: Ken, my refurbished Sony FZ arrived today. Now I'll be able to burn and play BD.
