Hi everyone. Thanks very much for all of your initial replies and posts in the first thread. It's getting a little long, so I thought I'd post a follow-up.
As what was expected with the HD chips, the camera will definitely have lower light sensitivity. I will need to test in some more 'real world' venues, however I did some final tests for now in my home tonight, pulling the light up and down (sorry, I don't have a light meter here).
The design of this camera is excellent in my opinion, and the menus are very nice. I basically set it up with an increased gamma & color gain, and set 2 of the 3 preset buttons to be 'Black Stretch 2' & 'Black Stretch 3'. I set the 3-way gain switch to be programmed at 0, 6 & 9db (you can set it in 3db increments - thanks JVC). Likewise, you can punch the shutter button and get 1/30th shutter, which you would want to monitor closely if using (rather than 1/60), but it does allow significantly more light in.
So - with these settings and 'quick buttons' to access, you could come up with a number of quick options depending on what level of low-light you're shooting in (ie: open the shutter, stretch the black by 2 or 3, add gain, add cam light, etc). I do expect I will have to run a mobile on-cam light higher than what I have typically, but I think I'll be able to come up with a good solution now, with options based on how far I am from the subject, and with the circumstances at hand.
Anyway - that's what I have in mind, and I look forward to more testing this weekend. Thanks again to many for excellent advice and tips.
Now - unfortunately, I can confirm that my particular unit does have the 'split screen' anomaly that had been mentioned here and there. I tested things tonight on a Sony PVM-8045, and I could see it pop up. The right hand side (split dead in the middle) gets a more magenta haze to it. Sometimes you have to look for it, and sometimes it's more visible. If I put the cam in very low light and switch the gain between 0, 6 & 9db and stretch and unstretch the blacks (via the preset switch), you can actually see the anomaly pop in and out and flicker. I think this was why I didn't see it at first, because it doesn't always seem to be there - it flickers in and out, stays, leaves, etc. Additionally, I should mention that I have never seen this split/flicker pop up under good or significant illumination.
It's nice to have found this forum, by which the anomaly was mentioned, as well as mention of JVC's resolution. I have had great luck with JVC ((3)DV500's & (8) DV550's), and I have found their service and support to be very good. Likewise, Ken Freed from JVC has always been an incredible wealth of knowledge, and very responsive to questions from every angle over many years.
I'm sure I'll need to return this particular unit, however, I'm positive I'll be keeping this little guy long-term (and I have another one on the way). Additionally, everyone I've shown this thing to loves it. Every 'can you do this' question they have seems to have quick 'yes' as an answer - it's just a cool cam. I'm also looking forward to their bigger guy that's supposed to come out next year, with great anticipation.
I'm sure it will all be taken care of. Hat's off so far - I'm looking forward to more experience with a nice little tool. Likewise, thanks for such a great forum. I learn from you all every day.
Best regards,
