GH2 Is anyone waiting on the GH3 before making a decision on their next upgrade?

Anything that you hate about current Cmos cameras would disappear, and you would probably lose resolution and

Just no more jello basically, or weird things when you flash lights at cameras. Or, that's about all that I know about that.

All current DSLR's have a rolling shutter, which means it scans the top of the image before the bottom. If you pan quickly, everything will look wobbly and skew, and if the camera is shakey, you'll get a very wobbly effect to your footage (often called jello).

A global shutter scans the image all at once, so you don't end up with those artifacts.
 
Yeah, if the GH3 had global shutter, that would be pretty awesome. Though I have to say, jello from rolling shutter has been the least of my problems with the GH2. My one concern after having shot with various cameras for little over a year now, is getting the most dynamic range possible. Never really clicked until I looked hard at Alexa footage for the first time, and then the original BMCC footage. I realized then, what an unbelievable difference more DR makes. So... if the GH3 truly shows an improvement in that department, then I'm really excited.
 
If Gh3 offers all the rumors suggest including a significant dynamic range boost, It will be a tough call. What is the mark-up going to be for the improvements, I assume a kit with the 12-35 will be close to $2k if not more. A Photokino announce will mean a late november release which will mean wide availability sometime over the winter if not spring. At that point BMC may have solved their supply issues and readily available, pick your poison.

I keep looking for the GH2 fire sale to start. It has been officially unavailable in Canada for 3 months now, whats up?
 
Quick question to Member/Mods who know.

How is the GH2's dynamic range compared to Canon 60d,5d etc....

With those cameras I have had great luck, lighting my scenes and using reflectors so for the most part I have been really happy. I still haven't used my GH2 on a production yet as I have been editing lately, but will soon (End of month early October)

Thanks
 
I assume it's pretty much 100% that the BMCC cam will have greater DR than the GH3, the only question is how much greater... 3 stops?

Given that, there is another issue for me that would be a big factor. People will hate me for bringing it up, but I can't help it, because it impacts the project I want to do - low light performance. Is the GH3 going to improve on the GH2 for low light performance? It will be a different chip, so there's a chance. So let's be big optimists and say that the GH3 will be better in low light than the GH2.

And now it brings me to the BMCC vs GH3. Yes, the BMCC will have gobs more DR - but if the GH3 can spank it for low light performance, I'm going with the GH3. After all, is the huge DR applicable across the ISO range for BMCC? If not... well, that's not quite as relevant to me, when I need to shoot stuff with very little light - I'd rather grab the GH3 in that situation instead of wondering about the DR in very low light from the BMCC. Not that I am even contemplating buying the BMCC - nothing against it, just won't fit my budget because there is so very much more you need to buy to make the BMCC sing, so it's much MUCH more $ than the GH2/3 when all is said and done... plus, an untested cam like the BMCC is like buying a pig in a poke - not my cup of tea.

So, for me low-light performance will be a big factor with the GH3.
 
Where's everyone finding these gh3 rumors. I cant seem to find any info if even speculation. I wont specultate myself, but find it entertaining when other do:)
 
4/3 Rumors has them...

=P And, I can tell ya that so far they're all true. Not like they haven't been leakin' though.
 
What would make me upgrade from the GH2 is if the GH3 has clean & recordable 4:2:2 24p HDMI output, 1080/60p for slo-mo, and if it fixes the various bugs the GH2 has. If it does those three, I'm definitely upgrading. If not, the GH2 + Orion V4b hack treats me very nicely. I seriously considered the Blackmagic camera, but none of my current lenses work on it, so I'll wait until they come out with a m4/3 version before plunking down $3000+ on it.
 
With the new GH3, I'm expecting better dynamic range ( 12 stops would be nice ), better high ISO shooting, and a beefier camera body. ( dual memory card slots would also be nice )

This would be enough to get me to switch up.

What do you absolutely need the global shutter for? Is Jello really that big an issue for you? There are other ways to prevent jello other than a global shutter. For instance: increasing the readout speed of the sensor will reduce it significantly. That is essentially all a global shutter is. It reads out the sensor with a zero second time difference from when it starts to when it finishes.

I would be willing to go one round with any MMA fighter out there in exchange for an AF100 with just this guarantee: a well-balanced sensor with as much "perceived" resolution as a Gh2 that will give you twelve stops of usable DR out of the HD-SDI.

Panasonic delivers that, set up the fight. I'll probably die very swiftly but still.

I would pay to see that fight. Not that I would want to see you get hurt. I would just like to see some MMA shot with the GH2/AF100.
 
Rolling shutter hurts vfx in the tracking department. I imagine that's by Erik wants it and I understand that point.

However, a Global Electronic Shutter isn't the only way to reduce/prevent the rolling shutter effects. A rolling shutter without the jello effect is much more likely to arrive before a true affordable Global Electronic shutter with a high megapixel sensor.

Hmmm...you think so? At this price point? I mean even the costly Red (not sure about Epic etc.) with its rolling shutter produces a bit of skew (not nearly as bad as lower end cameras). But I’ve been seeing some relatively cheap global shutter security cameras out there in the wild already. So….who knows…

EDIT: I think they are low resolution sensors though

Yes that is the key. They could make an affordable camera with a Global Electronic shutter and a low resolution small chip sensor right now. Once you increase the megapixels it becomes much harder and more costly.

I think the number of pixels is the only thing that truly affects whether it can have a global shutter or not. However, the size of the sensor definitely affects the cost.


The Phantom Flex has a global electronic shutter and shoots 4K video. It also costs $300,000 though. Getting a 16+ megapixel sensor to do this is definitely a different story. Maybe a crop mode could do a global shutter?

Yeah, when I was watching Haywire and I kept seeing skew in the fast pans and I had to pause the movie and check what it was shot on, I thought they must have been using a DSLR for some shots. But I found it it was the original Red, which also has a rolling shutter.
 
Having a global shutter for the subject matter that I shoot is an extremely big deal. Sure rolling shutters have their work-arounds but with a global shutter you don't have to deal with the constraints. This can allow you to get more creative shots.
