  1. Well, this looks very interesting. I wonder how good it'll be in low light, since I'm used to shooting at f1.8 with my Sigma 18-35mm, so I'd be losing around 1 stop shooting only up at 1600 ISO. Would you say 3200 compares better or worse to the GH2's 1250 ISO, @Andrew?
  2. Now this is getting me going. I was just about to make my jump to the GH4, but just like you did with the GH2 back in the day, you're making me reconsider my purchase, Andrew. There is a big difference in price, but the lack of V-Log L and the recording limit, as well as the lack of mic jack are making me doubt this combination. Now the argument is heavy, it is an awesome combination and I'm spending pretty much the same amount. So, how do you think the G7 stacks up in higher ISOs? Is it better or worse than the GH4?
  3. The GH4 may be soft at 96fps, but shoot at 50 or 60fps and you're in back in full HD, way more detailed than the 5DIII's 1080p (almost the same as 1080p24 on the GH4). And still at 96fps it stands a lot better than Canon's 720p...
  4. Wow. Do you shoot video or photos? I bought it for my GH2, and MD lenses have manual iris and a beautiful focus ring. So there.
  5. I don't like that A mount on the Sony. Why no E mount? What's the "adaptabilty" on the Alphas? I remember I bought an MD lens that came with an MD to A adapter and it had a lens for infinity focus... :S
  6. But the difference between 8-bit and 16-bit is pretty obvious and more in the ballpark of this test. However, since most of us don't have 4K monitors maybe the test won't be very evident. And from what I understand (and most here agree), bit depth can't be improved, can it? It's only the color sampling that actually improves.
  7. I think the Black Magic Pocket Cinema Camera (that's the full name, right?) goes like BMPCC. So that's one more C thatn the Production Camera. Actually I thought I was seeing wrong and my mind was closing the C. I think BMPCC is easier to difference on the spot than BMPO which at first sight might confuse some (or maybe just me) that it's written BMPC. Well, I'm nitpicking, just saying since it's the first time ever I've read "BMPO" anywhere.
  8. Sure, let me clear this up for you. I read all you comments and, to start clearing things up, I perhaps was confused by your key words to read, which got contradicted when you mentioned that "the 5D3 at 1920 x 720 looks more appealing to me than the BMC piece at 1920 x 1080(which is being streamed as of right now).", since the streamed version was 720p at the time you commented this (and at the time I mentioned that you had watched a 720p file if you only watched the streamed version). So did you actually watch the streamed version at 720p or the original uploaded file at 1080p. To see the answer, jump over the next paragraph. But, since you were being condescendent to me, let me clear this bit up for you first: Vimeo only converts to 1080p by request of the user and only if he/she is a Plus or Pro member. Do you know what that means? It means Vimeo tries to save bandwidth (and perhaps take care of the users with lesser machines that maybe can't play 1080p right). Well, that's speculation on my part. But you don't care what Vimeo does. So let me tell you: did you know there's a little button to the left of the "full screen" button on the Vimeo player that allows you to see the real pixels (only when you're in full screen, mind you)? Thanks to that you can see whether or not the user who uploaded the video has upgraded it to 1080p or not. James hadn't at the time you started all this (and you could also tell by looking at the download options). But you can tell whether or not a video is 720p or 1080p, right? I mean, since we're coming from 4K, it should be pretty obvious. Yet, again, the BMPC video at the time of discussion was being streamed at 720p (1280x720 that is) and the 5D video was being streamed at 1080p (1920x720 is 1080p cropped, you see) and you didn't notice there was an obvious difference that could very well be due to Vimeo's de facto system? Oh, right, you don't care what Vimeo does. So why argue? No argument then. It's enough to just take a look at the pictures you uploaded in >this post, comparing the BMPC video and the 5D video, saying how bad the first one was, how soft and all... You see, that pic tells you off. It comes from a 720p video, even if the file's resolution is 1920x1080. So indeed you were comparing a 720p video next to a 1080p video (and not the 1080p originals like you're trying to make us believe you did) and saying the first one looked soft. Well, of course! Just to be clearer still, here's your grab next to the current 1080p upgraded streaming version of the BMPC video. You're welcome. Sorry for my tone, but I don't like being condescended. Your statement was confusing and I thought your opinion on the resolution of the BMPC made no sense, so it had to be that (according to the second part of the conflicting paragraph) you had watched the streamed 720p version of the video to arrive to such conclusion, and not the originally 1080p uploaded file. You confirmed my suspicion with your posted framegrab and still you you denied it and talked down on me. Why not have a little self-criticism? Now we go back to discussing dynamic range, tonality, grading and all that. Cheers!
  9. Yet you started this thing by comparing a 720p video from the BMPC and a 1080p video from the 5D. At least rethink your arguments over a new comparison either having them both at 720p or both at 1080p and see how it holds up.
  10. I second you. I don't know if there's anyone in this forum that has a 1DC, but if you do or have access to one that'd be great. Oooor does anyone know if there's any raw footage, a clip that comes from the camera and is uploaded in some site? Perhaps we could ask Philip Bloom? :P
  11. At first I was very excited, but thinking this over I don't really see how 8bit would turn into 10bit. 4:2:0 to 4:4:4 is definitely right (and I'm wondering if there are any DNxHD flavors to save that info) but one thing is to change the color sampling by downrezzing, and another to increase the color palette by doing this. I guess some testing needs to be done. Probably 4K footage from the 1DC would be a good subject?
  12. At least in this case, doesn't it look more like a grading decision? Sort of like a cross-processing, with the blue channel lifted in the lows and lowered in the highs.
