Is the gh2 the new low light high ISO DSLR king

Highlights are where ALL the DSLRs fall flat on their face for the most part.

There's a slight enough difference that sets the MKii apart from the GH2 in roll-off, and the way the one-hundred clips. It bugs the heck out of me on the GH2, but I feel like I can control it better on the MKii.

Have you tried smooth w/ -2 contrast on the GH2?
 
Well, there are some specific facts released by Canon, and then there are rumors.

The facts are:
The digic5 chip is out, already found in consumer cameras and multiple times faster than the Digic 4.
Canon has announced that the 1Dx will have extremely high quality video, with full frame resampling and a 4:2:2 codec complete with timecode (features traditionally reserved for full sized production work cameras). But this camera will cost somewhere around $7k.
Another fact- the 1Dx isn't using the normal digic5, but rather some enhanced mode digic5+. What the plus means is still somewhat of a mystery, AFAIK.

But now, the rumors:
The digic5 chip is fast enough to do resampling instead of line skipping, and all new Canon cameras will be resolving video this way from now on. Some question whether or not this is feature reserved for the "+" model, however I think it is more likely that the plus means higher end features not found in other DSLR models (like the 4:2:2 codec). Just how many of the 1Dx's features are reserved for the digic5+ remain to be seen.

The other rumor is that the Digic5 will show up in a low end affordable T4i as early as February. The Rebel Ti series, following its nearly annual release schedule, is usually launched somewhere around Q1, and since the Digic5 is now out and available in consumer models, there is very much reason to believe it is the new standard for all Canon cameras, leaving the Digic4 behind.

So basically, what is likely but still unconfirmed, is that there will be a T4i announcement in the next couple of months, that it will use the Digic5 chip, and that the Digic5 cameras will properly resample the video as described above.

If this is true, its worth waiting for in my opinion. Especially because I already own and enjoy some native Canon lenses for photography.

But some say that Canon wouldn't release a Rebel camera with a Digic5 that fixes the video glitch before a new 5D and/or 7D are out first. I'd like to think that Canon doesn't really care about what feature comes out first. The way I see it, the video frame re sampling is not a "new feature", but rather a fix for a glitch that plagued the old models. After all, the articulating screen and 3x zoom mode didn't seem to stop Canon from rolling those features out first.

That's what worries me that Canon will use the sh**y video downscaling even with the new processor to protect higher end cameras and VIDEO CAMERAS or something similar to what Sony does which is still nowhere near what the GH2 can do! And all this wait will become just waste of time

LOL !!!

Funny how the gold standard of a few years ago is now sh**y video :)

I happen to be one that inspite of it's drawbacks still thinks the Canon image is top of the rung. I'm afraid that to solve the issue with the Canon's they'll lose the look that makes them so desirable in the first place.

They were desirable because they provided a look that was unavailable unless you wanted to deal with a clumsy adapter and lose a stop or two of light. Doesn't mean the images couldn't be improved. In this current generation plenty of cameras can provide that look without many of the pitfalls.

The video-optimized C300 looks great to me, miles ahead of the current crop of DSLR's. Gobs of dynamic range and sharp as hell, I don't know how anyone could think that the soft image loads of moire and aliasing were desirable traits.

Honestly, they could have easily crippled the Rebel series if this is what they were after. I personally did not expect the T2i to have roughly the same video quality of the 7D, and many more didn't believe it until it came out and saw footage side by side. They didn't have to give the T3i manual audio like the 5D either, or the crop mode. But they did. Because Canon's strategy appears to be standardizing common features, not crippling low end models. The 1Dx has some pretty high end stuff that probably will be model specific (4:2:2 codec, for example), but the way the video is sampled likely won't be one of them.

Again, none of this is set in stone, but I would be EXTREMELY surprised if Canon turns to crippling the low end.
 
One thing I am more or less certain is that we won't find two digic 5 processor in the low end camera. So how much could it impact the video down-scaling and sample rate codec, we will have to wait. I don't know if one digic 5 will be enough for all the 1dx video capabilities. One problem with companies, is that when they have time they tend to think about product segmentation and maximise their profit. All this dslr craze came as a surprise and they did not plan accordingly. See the pricing of the C300 which baffled most, very nice image but with an unrealistic price for many.

The new sensors will be thought out a lot with video in mind, but even if they rationalize their line at the 7d to ti line, they might cripple them with the firmware. But in the end, I think that there will be progress even at the lowest level. I don't see Canon coming out with the same moire/aliasing not full hd image quality of the present generation.
 
I don't know I'm still skeptic about this, all because of Sony anyway... I know that Canon is not Sony but they're in the same situation at the moment , new video dslr/mirrorless line along with 2 high end video cameras. Sony said that they fixed the moire issue instead they did not, the nex5n , a77 etc still show those problems and the image is not 1080p just a step forward in terms of resolution versus the previous models ( which were on par with the current Canons) instead the videocamera are FANTASTIC probably the best out there in terms of sharpness.
 
Moire and aliasing are WAY overblown issues. Rarely encounter them and when I do it's usually fixable with a slight focus adjust. Rather not have to think about it, but it is what it is (a $2500 camera). The bad tendency for rolling shutter in the 5D bothers me much more. You have to be SO controlled in the way you move the camera.

You don't get it the moire is just a consequence of bad/fake resolution so what bothers me is the fake res that I clearly see not its consequences
 
What is nice with the gh2 is that I have forgotten about the moire and aliasing. Sometimes I get a little aliasing on some very fine electric wire, but I really have to look at it. I use to see both of them in people eyebrows. The last thing I don't bother anymore is the over heating. Living in quite a hot climate my 7d was always overheating. Now if we could get less rolling shutter and 8 bit banding, we would be very close to get the perfect (good enough) camera.
 
No, there isn't a difference in the sense that a 28mm still camera lens doesn't have a 28mm field of view on a crop sensor camera no matter what mode you're in. My intent from day 1 has been to shoot on vintage still lenses so any crop sensor camera created issues at the wide end of the spectrum. If I could afford cinema glass I wouldn't be shooting on a DSLR. I also come from a film photography background so I didn't want to screw with the way my brain thinks of focal lengths.
Which is why I asked the question. Sure....you are looking at it from a "photographer's" point of view and not from a cinematic point of view. From a "photographer's" POV the crop factor weighs in heavily because you are comparing it to a Full Frame "stills" sensor. But in regards to motion picture there is not much of an issue which means a 28mm on the GH-2 would be slightly smaller than a 28mm when comparing it to a 35mm motion picture camera. The Canon 7D and other ASP-C cameras would be slightly bigger than the GH-2 (7d/1.6 vs GH-2/1.85) but are close enough to 35mm motion picture cameras. In video mode when you compare the image of an APS-C sensor camera like the 7D/T2i with the GH-2 you will notice the Canon is only slightly bigger. That's because the GH-2 uses all of its "oversized" sensor (compared to a typical M 4/3s sensor) to aquire its 16:9 image while the Canon (and other APS-C cameras) crops theirs. So, in terms of video....if you have an issue with one you will have an issue with the other (only slightly less). But when it comes to stills...then yeah....there's a big difference when it comes to field of view. But buying cinema glass or shooting on a purpose built cinema camera wouldn't change anything because you would still have you perceived issues with the "crop factor."



Right, I know, but I'm using still photo lenses. Like I said, to get wide on a crop sensor you either have to use modern glass or pay a very high price for vintage glass in the 10mm to 18 mm range. If I could afford to shoot on cinema glass I wouldn't be shooting on a DSLR.

Not sure if you realize there are quite a number of non-cinema lens choices for the M 4/3 that are much wider than the ones you suggested. But sure....not a lot of "vintage" lens that goes that wide.

I'm going for a very specific look, so shooting on glass from a specific era. I basically don't shoot on modern glass ever, though I am thinking of trying out the Zeiss Compact primes sometime. Like I said, I looked hard at the GH2, it's a good camera, but I went in with the intent of shooting on a certain type of lens (at least for a while) and FF just worked better.

interesting.. can you please upload an image of your specific look (from a film or something)?

Ok, this is a commercial I just finished, not totally representative of my films. I shot it for basically nothing for a friend who owns a bar. It has good moments and bad moments chromatography-wise, I had to shoot and light it myself rather than using my regular DP and on a very compressed schedule. I'm a director and writer more than a DP or operator. That being said, the opening shots of the girl and the shots of the girl on the couch both show the natural softness and warm tones of the lenses pretty well.

I just like the look. I have had chances to shoot on L glass, and prefer these lenses.

Well it sucks if I ever decide I want a wide shot at f/11. And it sucks when I have to spend extra time making sure wardrobe choices are kosher (and there are lots of fabric types that I've seen moire even if the pattern is not complex).
 
I want to see what that ISO 10,000 video looks like before noise reduction.

Crops out of 1080p from Driftwood 176mbps GOP1 etc etc etc, first shot tungsten balance, smooth, -2 on NR, nothing done in post, second is same, but daylight balanced. Second is well overexposed for the incident light (getting everything up to the right without blowing), if I turned camera around, cars, fence, ground etc blown out (flat lighting too).

The forums are making these images a fair bit smaller too btw, so you'll prolly need to open them in a new window.

I guess I have just been lucky. The couple times I have shot exteriors with details like brick that could have caused an issue it didn't and fabrics (like the fronts of the speakers in the commercial I posted above) are easily fixed with a slight focus adjustment. Compared to the larger issues of rolling shutter, narrow dynamic range, tendency to blow out highlights in a very ugly fashion that are common to all CMOS sensors I am aware of are much more of an issue.

Thanks for these crops. That actually looks okay. Similar to ISO 3200 on a 7D - chroma noise is ugly, but a touch of noise reduction should fix it up very nice. And 99% of the time I probably wouldn't even go higher than 3200, but it's nice to have the option of going outside at night and shoot without having several thousand watts of lighting at my disposal.
