  1. It's all a bit regional as well. In Sweden Sony or Panasonic drops so fast it's scary. People aren't using them. And the NX1 is just crazy.

    Canon on the other hand... A used t2i still holds over 50% of its last retail. After all these year's.

    I bought my Gh3 two months after release for 50% but a 5dmkiii...  You're looking at premium prices unless the display is cracked or something.

    Its as simple as a long tradition of Canon. They opened a service center in Sweden a long long time ago and that was it. 

    Same with Sega Vs Nintendo. The later opened an office here for Scandinavian NES releases and that was it.

    I need to get in touch with some Swedes...

  2. Yes and it also shows A7s' selling for $1100 last July, shortly after release. Right.

    I saw them selling used for around $1800-$2000 immediately after release. Used value on cameras ain't what it used to be. 

  3. Rumours were true they did reach out but not sure much came of it, they also reached out to me over a book but nothing came of that, I think they are just scouting / testing the waters really. They did a great job on the NX1 let's hope they can now do a great job on a raw shooting full frame camera ;)

    By the way if 10bit is the 'holy grail' even when compressed, why isn't everyone on this forum shooting 14bit? :)

    200mbps 10-bit is a far cry from uncompressed 14-bit DNG for file sizes and workflow. 

    It seems to me with storage prices plunging lower and lower, double the files sizes for quadruple the tonal precision seems like a fair middle ground between 8-bit 4:2:0 and uncompressed Godzilla files. It's not "the holy grail"--no one said that but you--but it is a noticeable increase in quality. Funny how you put down the importance of higher color depth after spending an entire article beating on the NX1 for not being as good with color as your 4:2:2 camera. 

    My money is on Samsung or Panasonic. The other important question is whoever puts a full sized HDMI out on their body. No, really. I think a lot of users don't even consider the 10-bit of the GH4 because micro HDMI is so breakable and easy to slip out during a take.

  4. I agree that it doesn't look right, but I disagree about the fringing. I see a flare issue with the Tokina and perhaps compression artifacts?

    Definitely purple flare on the Tokina, but I see that with a lot of older lenses.

    If you have time, I would love to see a comparison between the 4K and 1080p modes, as well as an over and under exposure recovery test, rolling shutter test, DR test (just a super contrasty scene, like a dark interior with a bright window) and a low light comparison, all on both 4K and 1080p. 

  5. I think I read somewhere that, like contrast, setting sharpness too far down causes problems. Maybe you could try a few sharpness settings and see what happens. I agree the colours look a little strange, but that may be down to the custom profile. Maybe you could do another video running through all the picture profiles with the same contrast/saturation/sharpness/NR settings so we can see what gives the best look. I like what I've seen of Standard, but there's very little out there to compare it to.

    Great work on the shoot, though! Backlit trees are a good stress test for the codec and DR, which both look solid.

  6. Deep crushed 100% blacks look video-ish to me, raised blacks look too instagram-ish to me, in-between is adequate, but more towards black than gray, say in a scale from 0 black to 100 grey, somewhere 40. It's a precise point you need to find YOURSELF for you TASTE. 

    There's an egyptian saying that goes something like: if it weren't for the variety of people tastes, no product would be sold. It ryhmes on Arabic though soooo, XC10?

    ...what?

    Crushed "blacker than black" is an important part of the film look. When the light falls off in film, it drops off fast and hard into inky blackness. Go watch any great movie shot on film and you'll see what I'm talking about. 

    Murky grey-black screams hipster video, and "don't crush the shadows" has always been a broadcast mantra with nothing at all to do with narrative filmmaking. 

  7. The thing is...modern LCD's can't really do blacks anyway. So you always have a differing level of "grey" at the bottom. That's why I still love CRT monitors (eventhough they are way shitty for desktop use)

    If you're willing to accept a narrow viewing angle, they can get damn close. Besides, consumer OLED is only a couple years off, and comes with the benefits of power efficiency, smaller size, larger color gamuts, and perfect viewing angles. 

    Regardless, there's a difference between the look of a display without perfect black levels and grading your video so badly that black becomes middle grey.

  8. I'm planning to sell my EOS M and pick one of these up soon. While it'll mainly be used with my Canon FDs and Minolta Rokkors, I will for sure be buying the 30mm f/2. It's a tiny pancake with great image quality, a wide aperture, and a nice versatile focal length. The best part: You can grab them used for less than $200. 

    If you're a hybrid shooter, why the hell not?

  9. good to know, that makes sense. There's not a lot of info out about this camera, so I suspect a good bit of trial and error. I'm gonna have to brush up on my grading and correcting so I can really understand how much I can push this camera. With my Canon's, so many people, before me, had already figured out the best mojo for them. Here's a stupid question... When someone says stops of dynamic range, how is that measured in an NLE? 

    It isn't. That's why they make text charts like the Xyla. http://www.provideocoalition.com/cameras_sony_fs700_dynamic_range_presentation

  10. re: Cineon

    I don't know what do you mean by R', G,' B' (gamma corrected values?), but Cineon encodes film densities which do represent scene light intensities logarithmically, the same way digital log curves do. It is indeed meant to be printed on print film. But the comparison is fair I think. If anything, one actually needs more precision for digital because print film grain, as fine as it is, still acts as dither.

     

    Incidentally, a few months ago I was involved with tone mapping and grading this real-time rendered short:

    It uses high resolution 8-bit textures, so the source image is effectively 8-bit RGB (4:4:4) and the engine works in high bitdepth precision and/or floating point (so negligible quality loss with lighting and processing). There is a (perfectly flat) log conversion operation from the engine linear space at the end of the pipeline for film out simulation purposes (simulated Kodak print). It is parameterized for around 12 stops. The grade is done over this perfectly flat curve. I found that somewhere around 12 stops is where you start to see issues if you are picky (and I am), even considering the pulled down whites in this grade and the overlayed grain.

    Wow, that's really cool! 

    ...but wasn't this topic about 8-bit 4:20 and 4:2:2 camera footage shot on physical cameras? I think we all understand that 8-bit can work very well for digital creations and is still the default delivery method, but the issue is whether it's an adequate acquisition bit depth for high dynamic range LOG-encoded footage. 

  11. Was anyone denying that a good sensor is the first step in achieving good image quality in video quality? No? Cool. 

    Was anyone denying that some 8-bit codecs can be pushed more than other 8-bit codecs? No? Cool. 

    Are people saying that higher bit depth is essential to getting peak image quality out of LOG files originally designed for 10-bit, like S-LOG? Yes. Posting examples of 8-bit C-Log footage proves nothing, because it's a much less steep faux-log designed for lower bit-depth cameras. So let's focus on some non-Canon examples. 

  12. I moved from Canon 5D III to Sony A7II, after 6 years with Canon.

    It's been only a few months but my experience is that LUTs (for video) or color presets like VSCO (for photography) are necessary for Sony shots otherwise they might look like taken by smartphones. Green shift, skin doesn't look so good etc.

    Sony should hire a Canon color engineer and also collaborate with professionnal photographers and cinematographers and work seriously on their feedback. It seems they are too focused on paper specs (dynamic range, more megapixels, etc.) 

    In the pro video division, at least, they do work with professional cinematographers on suggestions and feedback. Look at the work they've done with Art Adams. He asks for it, they provide it. He suggests it, they design it. They're incredibly responsive. 

    On the stills side, I haven't seen nearly as much of that. Battery life is still a massive problem for most professionals, as is the lack of 
    adequate professional support and lossy RAW compression. Problems with prosumer video are either ignored or aren't addressed until much later, when they're almost ready to replace those models anyway. 

  13. 4:4:4:4 12 bit raw means nothing if the sensor's readout or photosite information is limited - it's the back end vs front end

    I think a few people made that point in regards to the BMC 4k camera.

    So many factors to take into account than 8-bit vs 12-bit, and log vs raw vs rec 709 - Ebrahim made this point really well in his post on all of this.

     

    Just find a camera that you like and learn how to light and compose better.

    By messing with instagram on my android galaxy s4, I have found myself getting better frames in my cinematography work.  Not endlessly speculating on what camera will give me what I need in codecs.  Just by shooting with a crappy camera and figuring out what I can squeeze out of it.

    It's fun to be black and white about these things, but there's a reason high-end cinematographers require Prores HQ at an absolute minimum. 

    Also, why's everyone bashing the BMPC? It's not great in low light, but the highlight rolloff is actually really nice. 

    Andrew: There's a slope of diminishing returns going on. 14 bit to 16 bit is a pretty small difference, 14 bit to 12 bit is noticeable but not huge, 12 bit to 10 bit is a drop in quality but acceptable if you want efficiency, and 10-bit to 8-bit is absolutely huge. 

    If these distinctions didn't matter at all, why would professional cameras offer 12-16 bit recording? If they could get the same results with less back end, don't you think they would? How can you argue against the importance of color depth when you just spent an entire article railing against a 4:2:0 camera for not matching up against the colors of your 8-bit 4:2:2 camera? How can you argue against the importance of bit depth when you spend so much time talking about LOG profiles, which are designed for the sole purpose of imitating the same tonal precision as larger-bit footage in a smaller container? 

    I'm not denying you your point of view. If you think 8-bit is awesome, okay. But it's important for a reviewer with your level of clout to be clear about their priorities and thought process, as that informs all your conclusions. Sometimes it feels like you've changed your mind about fundamental things without telling anyone, which makes your thought process as a critic a little inconsistent and tough to follow. 


    Sorry if this comes across as rude or over-critical, because I don't mean to be. I've written as a film critic for a few years and I know it can be a struggle to get people on board with your train of thought. But there's an important difference between "10-bit doesn't matter" and "10-bit is nice, but I don't think we need it. Here's why."

    Just a matter of clarity. :)

    Cheers.

  14. I've just picked up an early shipment of the camera here in London! I'll do a field test and an evolving review over the next few days on my blog if anybody's interested! :-)

    Full frame vs APS-C mode.

    High ISO.

    Rolling shutter.
    Color rendering in all available color matrices.

    Resolution.

    Over/under exposure test. See how the sensor/codec responds to bringing up underexposed footage and bringing down overexposed footage. 

    Highlight/shadow rolloff. See how the camera renders a normally exposed scene with one or two very dark shadows and another with one or two bright highlights.
