enjoy the noise on this 2 minute 40 second footage we shot using:
HPX170
Letus Extreme
C/Y Zeiss
Regular Cine-D settings w/ "-8 Master Ped".
i got confused looking @ this footage on Final Cut,
seriously... my hvx200 didn't even produce this much noise.
we used 2k tungsten + 4ft4bank KinoFlo
&
no gain

try boosting the gain up to 9db next time and see what happens.
this actually reduces noise for me in low light situations believe it or not.

I actually tried +12db filming a wedding recently and the noise is there but ... not as bad as it should be. But know if I should stay on Cine V or it's ok to stay on Cine D?

Tose lenses are sharp. did see the noise but your art direction made is less of a distraction.

You guys are beginning to freak me out, I have had my 170 for three weeks and haven't had any time to shoot anything except some tests for my article. I did not see excessive noise and shooting against the HVX200, I saw much greater picture detail.
My 170 generates much less noise than my HVX ever did. Why are you getting such a different result?

I think people are comparing it to the 200a which has a reportedly cleaner image than the 170.

Jan made it seem like a camera to camera issue. They just need to put the two side-by-side... they being those who've noticed this issue... and do a comparison shoot. Oh wait they are doing that!

just got my camera back from panasonic today... had to go pick it up from UPS center @ 9:45pm because they typed in my address wrong, had me waiting the whole day for it, and finally i tracked it and it shows address not available.
i don't want to say "wth is panasonic doing" because they corrected the issue of the lens wobble, but we discovered the noise issue and they are not recognizing it, & now shipping my camera to wrong address. wth is panasonic doing?

geeze, I don't mind a bit of noise, actually a prefer a little bit, BUT
that is really excessive and distracting.
I'm not understanding that the noise levels differ from camera to camera???

Cine D is much more noiser than Cine V, from what I've read and seen.

i guess my point is that panasonic keeps claiming the 170 image is identical to the 200a, evidently, the 170 is much noisier than the 200a, it can be compared to the regular 200, but yeah... no idea wth happened this time around...

Barry and Kholi each have their hands on 200As and they are going to shoot some side by side motion tests and post the results. Stay tuned!

Go for it! The more samples we have to look at and analyze, the better the conclusion one way or another.

test & post please, thanks. i had a couple files of barry green's scene files, all so extremely noisy. perhaps only the "low-noise" was not noisy, but the image did not look good.
i do not recall the hvx200a being that noisy ever in 0db

Just a heads up which footage is which...
0:28secs - 0:41 HVX200A Cine D
1:15 - end HVX200A Cine D
Everything else is the 170 Cine V

That's why I was saying download teh 720P file... I believe you have to have an account at vimeo.

I've seen this kind of noise a million times. Most of the noise seen in the clip is the ground glass from the LEX. What f-stop was the Zeiss at? what shutter speed was the 170 at?

THE BIGGER problem is distinguishing 170 from 200 footage.

I spent a day last March testing the shutter speed limits with my LEX from f1.4-f5.6. I lit a focus chart evenly for every combination of shutter speeds and f-stops, and then assessed the clips on FCP6.
I used:
HVX200 @ 720 24PN
Letus Extreme (new Nikon mount)
Nikon AF Nikkor 50mm 1.4
Results:
f5.6 acceptable at 180
f4 acceptable at 1/60
f2.8 acceptable at 1/60
f2 acceptable at 1/120
f1.4 acceptable at 1/250
These are the limits of the LEX. Never shoot a faster shutter speed than 1/250, and never shoot past a f5.6 on the external lens. you can always do what ever you want with the f-stops on the cameras built in lens.

original clip = wide open @ 180 degrees shutter.

Weird, this grain looks exactly like LEX groung glass, but if your settings are what you say they are that's not it. All I can say I've shot similer stuff with the same settings on my 170 and it's not even close to that noisy. I'd send the camera back.
