Would the GH2 band be acceptable on the AF100?

RieniO,

Again, I wanted the flares. The flares were never the issue. I sought them out. I also did not point the camera straight into the sun. It was close, I'll give you that, but it was obscured a lot by the leaves, roof and the trunk of the tree. It's not like I centered the sun in the frame.

What lens was that? Any Filters? What were you exposing for?

The purple cast is horrible...

All of the GH-2 banding issues I've read about have involved very high contrast situations, most of them from people trying to film the sun directly...

DvxHerb, what sort of ND filters did you use to bring the light intensity down to a normal range ?

Without proper ND filtration it's like looking directly at the sun with 8 inch Celestron telescope and then complaining to the manufacturer that you just burned the retinas out of your head.
 
Many CCD's do vertical streaks on very bright objects, this CMOS sensor does horizontal streaks. I know people who would pay big dollars for that horizontal flare plug-in!
 
So the basic consensus is that the band is only a result of potential warranty voiding behavior by a fool?

Others will assure you that the band presents itself, to varying degrees, under normal conditions. My test just accentuated it to unholy proportions.

I didn't help myself out by not linking to the 28 page thread about the band:

I sincerely apologize to those here that I have either frustrated or bemused. At no point, did I intend to chide, admonish, belittle any of you here.

yes. how dare you come to a panasonic website and ask about defects in their products. begone you fool! you wench! how could you claim panasonic's holy products are imperfect? That is sacriligious.

Avant thee! Dirty hag! And don't try to trick us by putting DVX in your username. we know you are a secret canon snoop. Be gone!

this is not a panasonic web site. it is privately held.

Ok I get you now, sorry for being slow! But again, this banding is different from what has been reported before. The position of your banding is not fixed in your frame; it follows the subject. So it might be just another flare.

Also I'm not saying that you are b*llsh*tting nor am I touchy about criticism on Panasonic products (I shoot with ANY brand!), all I'm saying is that I would never shoot that way so the chance that I will get this kind of banding is very small, and again, if I would get this banding under normal lighting conditions I would not accept that. But as others have pointed out, you can't compare the GH2 to the AF100. The GH2 is a very cheap consumer cam only interesting for professionals who are willing to pioneer and pioneering means having to bite the dust from time to time. You probably discovered another weak spot in this consumer cam, but the AF100 is aimed at a totally different kind of end-user.
 
heavyG,

My wife appreciates you knocking your sarcasm down 20%, it gives her 20% more room to run...

I used a 50mm 1.4 Nikon at 2.0, shooting at 1000 ISO.

I wanted a washed out faded dreamy image. The purple happened and doesn't bother me.

At no point was I attempting to expose properly.

It's people like you who make forums like this funnier than Monty Python sometimes :-)
 
I have the Lumix DMC-LX5 and it has a CCD chip, AVCHD Lite. If I shoot video in bright sunlight at the right angle, I get the purple haze with vertical banding. So considering it's a different chip (CCD vs CMOS) and slightly different codec, I don't think it's something unique to the GH2. I think you need to use ND filters and watch your angles.

Hi Herb,

Is there a simple recipe to reproduce this banding problem ?

I have a GH-2 camera that I bought last week, and will gladly confirm the banding issue if some one can provide instructions to reliably reproduce the banding.

I suspect that some GH-2 bodies might have manufacturing defects and thus need to be replaced, but I also suspect that some people don't understand the limitations of current sensor technology when trying to film extremely bright ( or extremely contrasty ) subjects.
 
Can any of you see the band in this video?:


Certainly it is not as apparent as my example.

Is Mr Lansing voiding his warranty because there is not enough light in his shot?

Yes. Now I would want to see what happens when the ISO was dropped down to 800 or lower, as this might just be a limitation of the sensor's sensitivity.

i.e. Don't expect clean dark blacks when filming contrasty subjects at 3,200 ISO.
 
Yes but it's a GH2 clip, not an AF100 clip. Then if you still question if the AF100 would be different than the GH2 and nobody can change that idea you could draw the conclusion for yourself that you should not buy an AF100 and move on.
 
I'm extremely confused. So you set out to create a bad image, and you're upset that you were successful? Maybe I'm misunderstanding, but you seem to be trying to force the camera to band horribly. So yes, a camera with a documented banding problem does exhibit that issue when forced. (And sometimes when not forced.)

Here's a similar example: The HVX isn't a great low light camera, and tends to be noisy at times. This is well documented. If I go out of my way to shoot in the dark, and "not bother to expose properly," would it be fair of me to complain about dark, noisy images? If a camera doesn't perform well under certain circumstances, you use something else when you're forced to shoot in those circumstances.

I get that you're unhappy with the performance of the camera, but I think you need to bear in mind that it is a DSLR. Video is a nice feature and all, but expecting perfect video images out of it under all circumstances is asking too much. I mean, if that were possible from a $900 camera...whats the point of anyone buying the $5,000 AF100? The $20,000 RedOne? The $60,000 Alexa? etc etc...

As for comparing it to the AF-100, I HIGHLY doubt this will be an issue. There's been a good amount of footage released so far, and alot of it has been torn to shreds in this forum...complaints of noise and blown out highlights top that list thus far...but I've been following this camera every day for months and have seen no mention of banding whatsoever. I think if it had a banding problem as bad as what you're suggesting, we'd know about it by now.

You shot at f 2, 1000 iso straight into the sun, and you think that there is a problem with the camera? Take any camera - any camera - and do the same test. Then come back and show us what happens. This is what I would expect from a $900 consumer still camera (any consumer still camera) that happens to have video capability. Just because you can shoot at high iso doesn't mean you will get a great image - even 1000 iso film will give you a crappy image.

Also what does this test have to do with your decision to by an AF100?

what is has to do with af100 is this: the gh2 and af100 may possibly share the same exact sensor. thus the link.

anyone contesting this point please show proof as to my knowledge panasonic has not yet ever released definitive information on what sensor truly IS inside af100 but early reports from Jan months ago stated that she believed it has the same sensor as GH2 to my knowledge so I am very curious to know whether af100 has an optimized (with different olpf) gh2 sensor?

not to play devil's advocate but i have shot into the sun with my gh13 on numerous occasions and it produced a beautiful image and never anything even close to what I see in thread starter's video (horizontal bands) so I think your point doesn't stand that strongly
