  1. Two weeks ago, it was "game over" for Sony. I'm starting to get whiplash over here! I'll probably buy Pro Color soon, I just got the A99 II and am probably transitioning away from the A7R II. Just getting settled with the new setup. I was using A mount lenses on adapter anyway.

    Nikon D500

    So a 1:1 center crop of the D500's 20.9 MP image to get a UHD frame results in a total crop factor of how much? My back of the envelope says 2.2 ish?
  3. Selling a substantial GH4 based setup, more details here: http://www.mu-43.com/threads/79426/ GH4 body with Varavon cage, 12-35, 20, 45, 7.5 fisheye, 45-175 PZ. Sigma 18-35 and MB SB to come soon.
  4. Had a chance to do my first filming test of the A7R II earlier tonight. We went to a glass blowing tutorial/class thing. Of course when you're standing in front of a 2500 F degree oven, things get a little warm and I was curious about how the camera would hold up. I didn't record a ton of footage but I did run the camera continuously for a 10 minute clip with no problems. The thing did get very hot in my hand - not uncomfortably so, but enough that I can imagine a prolonged day of heavy shooting would begin to stress the system quite a bit. It's not a problem for my usage, but I think others w
  5. ​Sensors don't have colors, but the internal image processing sure as hell does. Actually, the Bayer filter array also has physical colors associated with it and not everyone is using the same colors. Still, it'd be one thing if we were all grading 12/14 bit raw output off the camera sensor but we're not talking about that. We're talking about video recording in 8 bit 4:2:0, which means the camera's color interpretation is heavily baked in. You can't just hand wave away the intrinsic color settings of a camera because of color grading. Color grade those blue clipped highlights, why don't you?
  6. If you're willing to consider a USB 3 drive, take a look at this bad boy: http://www.amazon.com/Seagate-Backup-Portable-External-STDA4000100/dp/B00HXAV0X6 It's actually two drives crammed into a RAID 0, crammed into a single bus powered enclosure. 4 TB, and I'm seeing it deliver in excess of 230 MB/s (yes, megabytes) per second in real world file transfers. That's SSD level sequential (but not random) performance. Comfortably fast enough to edit on! They include a free NTFS driver (Paragon) for Mac which works extremely well. And just look at that price. Really cannot recommend these highly en
  7. CPU/mobo/memory: The new X99 platform is great for high end production tasks. An i7-5960x is right about a thousand dollars - less on sale - and gives you 8 cores, 16 threads. The motherboards have tons of options for high end storage arrays, USB 3 ports out the nose, optional Thunderbolt 2, the works. Support for large memory configurations means you can buy 32 GB (4x8) right now and upgrade to the full 64 with the remaining 4 empty slots at your leisure later. GPU: Honestly the 970 is great, despite the weird memory quirk. But the 980 and maybe even a Titan are worth looking at. I'm in the c
  8. Can someone suggest a lens with great, attractive flaring? Modern lenses flare in a way that looks awful. I need to let my inner JJ Abrams loose
  9. 24, 35, 85. Always found 50 to be an obnoxious non-committal focal length myself.
  10. I'm going to borrow something I posted on DPR. That's strictly from the perspective of 4k content display (which is not necessarily the same as 4k content delivery). The arguments in favor of 4k capture are vastly stronger than the ones for delivery or display. We're talking about significant improvements in resolution, color resolution, post processing latitude, etc. Don't forget that the video we're getting off many of these cameras is only theoretically 1080p, but is in fact only resolving 600-900 lines in 4:2:0 color space. That's a lot less data than a true RGB image containing 1080
  11. I work in real time 3D graphics (read: games) and unfortunately people have a habit of dissecting the hell out of screenshots. I mean Halo was excoriated over rendering at 900p instead of 1080p and then doing an upscale. Can you imagine someone complaining that a movie, even a CGI movie, was only delivering 900 vertical lines of resolution when screenshotted? That would be insane. Unfortunately it has led to emphasis of technical parameters over aesthetic quality, and so a lot of these supposedly high quality games look awful. I don't feel that the art direction in many big name games is compe
  12. Lots to think about here. Thanks everyone - happy to hear more thoughts from others as well. I am personally fairly young and got into all this stuff only three or four years ago, so the idea of beating out film is totally foreign to me. I'm coming in fresh and trying to figure out where I'm at. Currently very happy with the GH4, but always on the lookout for the next big thing... Funny you guys should mention Fincher. Got to chat with him when he was filming Social Network on our campus.
  13. So as long as we're on the subject - what IS the current feeling about the GH4 vs the NX1 as hybrid cameras? (So taking both stills and video into account.) Both are obviously excellent cameras, but are there any key points to tip one way or the other?
  14. Yeah that was confusing, but I think he's saying that A is the video frame, because B is the one with the color fringing that wasn't removed from the RAW file. Which, thank god. No denying that the video output of the NX1 is absolutely fantastic, but I am deeply thankful that my years of work in imaging are actually able to stand up to a test :o But I DID have to think about it for a few minutes before answering. The lack of fine color gradation in the video frame, plus the smudgy shadows, are the only things I would've maybe caught at a casual glance. The more subtle stuff - the macr
  15. Canon's made it clear that they don't consider DSLR video to be a serious thing. And for those who do consider it to be a serious thing, they can go buy or rent an EOS Cine series product. And by all accounts, they're quite happy with how this has worked out. Hoping for anything else from them is simply irrational given their statements to date.
