@AdR Nope. Its 50 shutter still.

@rajamalik I can't answer the other questions but @driftwood said that you cannot set the shutter speed to 1/48, only 1/50.

@Mihuel, yes there are more important things, such as sorting out the euro and the unemployment issue throughout europe? But in any event, I do find it kinda incredible that if the GH3 wants to be regarded as the pinnacle of hybrids they should add the 1/48 shutter and the 48fps, but then they'd need 1/96 shutter too? It is also really frustrating that these cams will come as euro, 24/25/50 or ntsc, 24/30/60, why not all ow people to dial-in the base set, 24/25/30/60? Canon/Nikon seem to be able to manage that bit OK.

@mee

Can you show some examples of why you think that single digit shutter speed control is important in the GH3?

The Rolling Shutter Affect and Frame Rate have more to do with it than single digit shutter speed control. Decreasing shutter duration will never help the Rolling Shutter Affect.

Personally, I feel its a great camera - a lot of people go on about everything else bar the codec. For me, looking at how this performs will show the true merits for video reproduction - and it does a bloody good job with adaptive 8x8 and 4x4 transform. High Profile level 5 offers us more power, allows larger macroblock size, better prediction and larger bitrates. Gh3 Stock is as good as hacked GH2 in my opinion but I wouldnt be able to resist playing with the 2 extra 8x8 scalers and the existing 6 4x4s to take it to another level. Until we see final firmware who knows what we can do with it... However, as good as it is, I do believe we will see a GH4 equiv from Pany quicker than we have waited for the GH3.

He never mentions the rolling shutter effect. However, he should have. I could use ANY shutter speed greater than the lights flicker duration with ANY lights if I had a global electronic shutter or a really fast rolling shutter and a fast enough frame rate.

Just because your shutter duration matches your flicker duration doesn't mean both are synched up to start a cycle at the same time. If my Rolling Shutter camera opens the shutter in the middle of the light's cycle you could see the same issue even with the so called "ideal" shutter duration.

Really this issue is completely misunderstood. There is absolutely no merit to using that precise of a shutter speed with these cameras.

@mpgxsvcd what you said has logic and good basis, but then how is oftelny solved at dayli basis. I we could have those 1 setp shutter adjusments, it could be more possible to SINCRO light and shutter , also opening more doors for errors.

@endotoxic

There is a really simple fix even with a rolling shutter. Just use a really long shutter duration. If your shutter stays open for 2x the cycle of the light then no matter what the rolling shutter does you will have equal exposure across the frame.

Now I fully understand this isn’t practical in a lot of cases. For NTSC countries that requires a 1/30th of a second shutter duration or longer. Most cameras can’t take 30 FPS video with a 1/30th shutter speed. Luckily our GH2’s can.

Try it. Select 1/30th or 1/25th instead of 1/60th for NTSC lights. The flicker will be gone. Now the motion blur probably will not be to your liking but the lights won’t be an issue.

Really the whole 1/(2x FPS) theory is not that precise. It is a great place to start but that is not always a hard and fast rule. It simply gives you more or less motion blur depending on whether you increase or decrease the shutter duration.

There is absolutely no way anyone could tell the difference between the motion blur from a 1/48th shutter duration and a 1/50th shutter duration. There I said it because no one else will stick there neck out there and go against the grain.

That is the problem with our perception of some of the new equipment that has come out lately. All it takes is one person to bring up a negative issue about the product and suddenly everyone will jump on it and make the product out to be completely defective.

The GH3 has some issues. You will have to be aware of them but in reality they will not be the reason why your work is not praised. The strengths of the GH3 will far outweigh any of its weaknesses.

Now that also doesn’t mean that the GH2 won’t be just as good as the GH3 for some scenarios. For 1080p @ 24 FPS video the GH2 is pretty darn amazing and a heck of a lot cheaper.

Of cause you won't see a GH4. They will "skip" it. The next would rather be a GH5 because of tetraphobia (same as with G5 and GF5). (o;

@mpgxsvcd @joesiv

I seem to remember there was some discussion of rolling shutter in relation to flicker/frame-rate in this article and the comments. http://blog.abelcine.com/2009/04/15/the-difference-between-a-global-shutter-and-a-rolling-shutter/

Shoot a Fluorescent light with a GH2 @ 24 FPS. Start with a 1/25th shutter duration and move all the way up to 1/250th of a second. You will see continuous dark bands form at various positions in the image once you reach a shutter duration faster than 1/120th of a second. Those bands are actually flicker. Their position will move as the shutter speed increases.

If the GH2 had a global shutter the entire image would be dark instead of just bands. However, once the frame rate increased past 50 FPS you wouldn't be able to perceive the changes just like you can't perceive(Or most people can't) the changes with the naked eye.

Here is a video demonstrating the Rolling Shutter Flicker Effect the GH2 exhibits. A faster frame rate and a Global Shutter would eliminate this affect. That or using a very long duration shutter like at the beginning of the video will work as well.

@mpgxsvcd what you say makes sense
