  1. Impressive!

    I love that this year's flagships are really pushing the envelope on DIS for videos. The Z5 series looks especially promising. Though it isn't perfect by any means, there doesn't seem to be too much warping or bending for such an aggressive motion.

    I'm also curious to see if the phones are compatible with the Cinema 4k app and what 200mbps looks like.

  2. Oh okay, I get it! Thanks guys! Seems pretty solid. Curious to see what the footage will look like and if anyone would do any DR tests (xyla chart or even informal ones).

    Btw, if you put a speed booster on this, would it cover the full size of the super35 image sensor? It would be cool if a speed booster could expand the circle closer to aps-h or full frame. I tried searching for details on this but can't seem to find anything. The Metabones XL page says it isn't compatible with LS-300, so I presume that means all of the MB mft speedboosters are incompatible. Still thought I'd ask!

  3. Yay, some love for the G7! :)

    Have you tested the actual crop factor of the G7 Andrew? According to Cameralabs it doesn't crop as much as the GH4 in 4K mode. Kinda weird, because that would mean it's not a 1:1 pixel crop.

    ​Huh, does that mean that with the SB the G7 becomes wider than 1.5x at UHD?

  4. This is insanity. I thought that the next big thing would be the A7smkii. But yeah, like others have said, I have relatively low expectations for the 5-axis stabilization because of the A7ii (although I'd love to be surprised). I'm curious if the dynamic range will still be as good as the A7s. Part of the reason the A7s has such great range is due to the fact that it has a 12mp sensor. Will it be as easy to achieve that with a 42mp sensor? Very exciting.

  5. For depth of field, I think it may be easier to tell if there was a greater space between the subject and the background. As it stands now, the keyboard and the desk are basically adjacent with not so much space in between. For exposure, there should have been a more significant difference, so I'm not sure what happened.

  6. What format will you distribute in? Online, television, theatre screens? If online, 1080p is definitely a safe bet with the advantages stated above.

    If you'd like to though, Mattias Burling showed that uploading 1080p upscaled to 4k actually shows a far cleaner image on youtube than uploading the 1080p native because youtube gives it a better bit rate. I'm sure 2.7k to 4k would be even better in this scenario.

  7. To be fair (and you're probably well aware of this), dynamic range tests are in a lot of ways subjective. It depends on how many stops is considered usable to that particular tester (noise levels, exposure clarity, etc). Add to that, people conduct the test in different ways (using different charts, profiles, differences in transcoder, firmware version and knowledge like you said), and it becomes even more confusing.

    I personally don't own the NX1, so I can't give you a definitive answer, but from all of the footage I've seen, it feels like the NX1 stops a little sooner in the highlights compared to other cameras, but that the highlight roll off is a fair bit more attractive. It seems like the NX1 benefits from underexposing a little bit instead of the other way around (though again, I may totally be wrong about that). According to Andrew's findings against the C300, "If the C300 can do 12 stops the NX1 can do 11.5." Cinema 5d pegs it much more harshly at 10.1 stops.

    To my unscientific eye though, I've seen footage that squeezed a lot of detail from contrasty situations in a great way, and some that fail dramatically. It really depends on the context and how much you really need for that shot imo.

  8. Are you already invested in a lens system?


    • Native compatability: Autofocus access (in camera-body or wireless tether), CA correction, stabilization
    • Relatively sharp lens
    • Good zoom reach
    • Fast, especially at the wide end


    • Fly-by-wire focusing
    • A little on the heavy side
    • Price (debatable though. this point depends on what you need)
    • Primes are generally sharper than zooms

    Personally, I think it's a great all-around option if you don't mind the fly-by-wire focusing. What's your budget like? AF isn't really a big necessity for video mode (it's more of a luxury if anything). In that case, depending on your budget, you have a whole world of lenses to choose from! On the low end, you can go for rokinon cine primes or a slew of ,older cheaper lenses. Sigma's Art series is pretty nice (the 18-35mm f/1.8 is really popular, and the 50mm is on par with the Zeiss Otus 55mm). On the high end, take a look at the Zeiss Otus 55 and 85. Take note that the Sigma and Zeiss lenses are best used for photographic purposes (as the focus throw isn't specialized for film, or might be too thin).

  9. Thanks for the detailed response arellaTV. What is the difference between 1080p on the NX1 and UHD? And I'm assuming the lower number on that list for rolling shutter is better? 

    You're welcome. ​They're two different resolutions. And yes, the lower the number on that list, the better.

    1080p = 1920x1080. It's the standard called Full HD that we've used for years (TV screens, laptops, and more recently mobile phones - though some phones even have 2.5k screens now!).

    UHD, or Ultra HD = 3840x2160. It's a much larger resolution - basically stack four 1080p images together into quadrants and you have UHD.

    The picture below should help. New cameras like the Red Dragon can shoot in 6k. If you're new to videography, you'll soon recognize all of these terms if you scour the internet. You'll find that a greater resolution gives greater flexibility (to reframe/ stabilize) as well as a greater amount of detail and color information when supersampled. Consumer or pro-sumer cameras have just begun to tread these higher resolutions at such a low price within the last 1 and a half to 2 years. However, you'll also find that there are a lot more variables to a good image besides resolution that are just as important.


  10. I've noticed quite a few videos of the NX1 showcasing some really really weird jitter, almost like someones twisting the camera side to side ever so slightly at a really fast frequency. Has anyone else noticed this? Ideally I would like to get this camera + the nikon sigma 18-35mm, and I know that means no OIS.

    ​You're probably noticing the rolling shutter. A user from DVXuser compiled information of the sensor readouts of several cameras, and the NX1 at UHD tops the list. Although interestingly enough, at 1080p the NX1 is ahead of the pack by a large margin. http://www.dvxuser.com/V6/showthread.php?303559-Measuring-rolling-shutter-put-a-number-on-this-issue!

    If you're looking for a camera without those weird wave like motions/ jitters, you'd have to either look for cameras with global shutter (e.g. Blackmagic Production Camera 4k), or look for cameras that have an exceptional IBIS like the Olympus E-M5 Mark II. With the E-M5, you could use the Nikon Sigma 18-35mm lens even though it doesn't have OIS. Or if you're dead-set with the NX1, you can combine it with a Nebula 4000 lite and greatly reduce the effect.

    If it's true that Samsung is updating the NX1's firmware monthly, then I hope it sets a precedent for other camera companies. It's most likely due to its advanced processor and flexible OS that they can update it so frequently. Although it's always nice to have new features that affect the image, I agree with the above sentiments that the next updates should provide more flexibility to the user experience of a videographer.

  11. ​Exactly. I wished they would have stuck to that 2.5K spec. Bummer.

    ​Yeah, I can see how a different sensor might be more attractive. They could have limited it to 2.5k, and then maybe they wouldn't have to sacrifice dynamic range (although I do like how the nx1 handles highlights).

    But a 4k interchangeable lens camera with a kit lens for $800 seems like a steal. If it happens to retain image quality from the nx1 (and let's us keep the dynamic range and contrast profiles), I would definitely be interested. We should be presented with more coverage in the coming days once the upcoming conference begins. 

  12. I found this from Imaging Resource's NX1 Review:

    Maximum clip length is limited to 29 minutes 59 seconds while maximum file size depends on the SD card's capacity and file system. For 32GB and lower capacity SDHC and SD cards, the card is formatted as FAT32 with a file size limit of 4GB. Larger SDXC cards are formatted as exFAT, with movie files sizes limited by the 29:59 time limit.

  13. When can we download the new firmware?

    ​They say it should be out sometime mid-January. I suspect that means within 2 weeks if all goes well. 

    The Samsung NX1 firmware version 1.2 update is expected to be available to the public around the middle of January, so if you're an NX1 shooter, you should have access to all of these new features in another week or so, two tops.


    Exciting times!

  14. Bravo, Christie English! Nice ninja work! It's greatly appreciated.

    You can see a little bit more detail in the picture with GammaDR. It'll be interesting to see how different the modes perform in 4k. With a quick peek, it feels like GammaNormal is the sharpest of the three.
