The end of 35mm adapers and hv20s....

I think our collective brains are having a fart! Its 3:45 am in New York and I am still reading this thread. And there is no conclusion on the rolling shutter debate. Is this a plot by Nikon to turn us into zombies or vampires?
 
I belived ISO had to do with how fast you wanted to capture an image withough blur. So, maybe if you set the ISO at 800+ the skew would reduce. But like Kholi said, this is just a problem CMOS sensors have and no real way to stop it until they "nikon, red, canon" or whomever get a better one. Mcgregor posted a clip of RED's build 15 that had just as bad skew if not worse.
 
\This is the HV20 and SCARLET I wanted, to be honest. Of course not a still camera, but they all will weigh the same and they all will have rolling shutter issues.

Nikon just punched me in the face with interchangable lens options and, well, sorry guys. But Rolling Shutter isn't enough to put this to the side.

If the exposure, iso, and shutter can be locked... no-brainer is an understatement.

Bumping the ISO up will A) INcrease Digital Noise B) Increase Light Sensitivity. It's a faux ASA, similar to film stock. That isn't the exact/right explaination but I think it's close.

It will not effect Rolling Shutter.

It must be getting late. We weren't talking about ISO/ASA... talking about shutter speed. :huh:

Going to bed soon. :beer:

EDIT: Oh man that was totally my bad, you were responding to someone else... jeez. I'm going to bed NOW.


PS: Kholi is right, ISO/ASA is not going to effect anything but the base sensitivity of the camera.

Bye bye
 
Please everybody

Please everybody

Please go to bed.

It is still 5PM in Japan so I will be waiting the other clip of D90 to be uploaded. (it stopped uploading at 99% when I came back from Gym. So I am uploading it again)

It will take another 40min to complete uploading.

So.....
 
Seriously, I have yet to see results as bad from the HV20 as the ones that were displayed by the D90 on this last video...except for an HV20 video where a guy shook the camera REALLY REALLY hard to try to get the rolling shutter effect...and even then it was not as bad as what we've just seen. I really cannot understand how anyone would be whiling to work with such an unreliable tool for professional purposes (or even for an important personal project for that matter). I would buy this camera for it's photo quality and I would for sure use the video option, but to a very very limited extent and with no camera moves...since we've just seen that even when you move the camera VERY lightly the rolling shutter side effect is seen.
Who knows, maybe it's not the final production version, maybe it can be corrected vie firmware. I would sure love to be wrong.
 
The HF10 I had, when zoomed in, exhibited the same exact stuff.

The RED does it.

HV20 is no different. Just zoom it in and pan and you'll see it. The longer the focal length the more apparent it is.
 
The only way to make rolling shutter go away is to make the scanning speed from frame top to frame bottom, so fast it's unnoticeable. The slower the camera is panning the less noticeable as well.

A firmware upgrade will unlikely be able to fix this problem. The rolling shutter has been a concern for me since the beginning, due to the enormous chip size of the D-90 compared to the HV20. That rolling shutter has to travel a much further distance per frame.

Your only solution is a faster shutter speed (unless shutter doesn't act like a real shutter), wider focal lengths (longer focal lengths are optical means of simply accelerating the pan... same thing as the next point), and slower pans.

Doesn't mean it's unusable. Perhaps one of the few drawbacks on a first of it's kind.


As you see, I'm waiting for clip #2 :)

Sorry, Kholi but I never got that kind of results with the HV20 zoomed in at maximum range. Of course I have never tried shaking it like mad, but that was not the case with the D90. We are talking simply about a fast pan, not a crazy shake.
 
I think it was determined that slow or fast shutters don't alleviate the issue. However, as I said and you just backed up, wider focal lengths.

It all depends on how you shoot, but, I'm mostly sitting on a 35 or 28 all day. Rarely ever touchin' an 85 or longer.

The good thing is that this camera is so cheap that it's just a second option to an HVX/HPX.
 
Depending on how fast the shutter speed would have to be for it to work and how well it would fix the issue I could reconsider my thoughts...which basically is why this thread was started in the first place, right? To hear my thoughts? ;-)

I don't think it was. I'm still waiting for someone to prove that wrong considering my experience with mechanical shutters would have an impact.

I'm open for a reason why it wouldn't effect the rolling shutter. The faster it rolls through, the less difference from frame top to frame bottom, leaving less skew.
 
Ask around in the EX-1 forum. Maybe you're right. Personally, I wouldn't even go to the measure of adjusting my shutter to something improper just to try and curtail the effect.
 
It's 10:35 in the morning here in Barcelona and when I went to bed yesterday you were still posting. Don't you dudes ever sleep?!
