Steven Mullen and the JVC

Steve Mullen has a lot of info on this camera at http://www.gyhduser.com and he had this to say about the split screen "I've believed, and I think others also believe, that the split-screen problem is related to high levels of gain. If this were true, the split-screen problem could be avoided by not using high gain levels.

It may be that JVC has suggested this to be the case -- or they hope it is the case. BUT IT'S NOT.

The fact is that the split-screen problem can be "provoked" at any gain above zero. So it can't be fixed by keeping gain low.

What provokes it?

Anything that causes the image to be sub-optimal coming from the CCD. I found two things -- which boil down to one."

I was wondering if him and Barry had any contact. I believe they tested this camera together originally right? Or am I off the mark here?

Never met Steve Mullen.

I'll have my HD100 on Friday (UPS willing) so I should be able to get to the bottom of a lot of things soon.
 
Barry,

The images i've seen from the HD100 are great, and the noise seems to be low enough for broadcast use..
The only two things that i am uncertain are the split screen effect AND the color aberration.

What can be done to avoid chroma aberration with the HD100 without buying a 10,000$ lense ?
 
Wrong Barry, but while you can't correct the chromatic aberration, you can try to avoid shooting at the focal lengths where it's worst. Once Barry Greeen does his optical testing, he should have a good idea of lens perfomance and at which focal lengths the problem is worst. FWIW, you can also try to avoid shooting bright objects against dark backgrounds--that really shows the chomatic aberrations easily.
 
Isn't it? It is more of a habit in the pro world I have to say... the JVC GY-DV700 is a $15.000 body. Many many of them are operated with lenses around $25.000 ....

It just shows you again (for if it wasn't clear already), this camcorder is designed by and distributed only by the professional division of JVC....

"Renting a $10,000 lens!! ;)"

it is not a logical solution on a 6000$ camcorder...

Sure it is. Although my original post was a bit tongue in cheek. Renting a lens for the HD100 is really one of the main advantages to the camera. You're, quite simply, not going to get a true HD lens in this price range. There's a reason the Canon H1 is nearly twice as pricey as the JVC, and it ain't due to the HD-SDI output. ;)

The H1 uses a pretty decent piece of glass (in terms of resolving power) in comparison to the stock lenses found on the HD100 and the Z1.

These cameras have interchangable lenses for a reason, and its certainly not due to the belief the owner/operators are all going to own their own pieces of glass for them.

Anyways... I'm bored. :)
 
Yes, the batteries are charged, and the camera's assembled, and ... well, heck, "Serenity" starts in an hour... let's see, $5500 "new toy", or $8 for the return of Joss Whedon's brilliant epic space western?

See you in two hours! :grin:
 
Serenity rocks Barry!!! If you loved Firefly you'll love Serenity. We can wait for your observations on the HD100.
 
You could wait for the DVD release of Serenity... and test the camera now!! $8 for a movie ticket? That's almost twice the price than here in Portugal!
