  1. I checked the Fairchild website since they use their sensors in the Pocket and Cinema Camera. The chip mentioned on bmcuser is the LTN4625A, you can find all the info on the website: http://www.fairchildimaging.com/catalog/focal-plane-arrays/scmos/ltn4625a

    It does tick the 4K @ 240 fps box, but it's a 12MP sensor, not a chip with exactly 3840x2160 pixels like Andrew is talking about.

  2. I was getting quite intrigued by this camera as it seemed like a good B-cam for run & gun shooting, until I've read that stabilization doesn't work when recording in 4K :huh:

    The lens has IS (in the lens), it does work when recording 4K. When shooting 1080p you get 5 axis Dynamic IS, which is a combination of lens IS and electronic stabilisation.

  3. Official video by Canon. With ugly clipped highlights... (1:00). I suppose it could look better if shot in C-Log and graded properly.

    Beyond the codec, what does this offer that the FZ1000 doesn't have?

    ​Wide angle when shooting 4K (27,3-273mm f/2.8-5.6). The FZ1000 crops the sensor at 4K and turns the 25-400mm lens into a 37-592mm.

    I prefer the FZ1000 form factor. It's a lot stealthier because everybody thinks you're taking pictures instead of video. This looks more like a camcorder.

    Also, it looks like the XC10 can't shoot raw photos. Which makes it a bit silly as a serious hybrid.

  4. The Nikon 1 J5 is official now. 4K at 15 fps.. lol. Reminds me of the Canon EOS 500D (1080p @ 15 fps).
    Anyway, this probably means the Nikon 1 V4 will get 4K @ 30 fps...

    I'm surprised they even used some of the choppy 4K in the promo video:

     

     

  5. Yeah, so you know where he gets his inspiration :) 

    Nice effort indeed, but a GH4 successor is not expected soon. I think it might come around Photokina 2016.  

    ​The GH-series has always been on a 2 year schedule. You can't expect a new model after just a year. 

    ​Also there are a lot of other cameras in the Panasonic line-up waiting for an update. GX7 and/or G6 successors will come first I think.

    NX1 H.265 4K to ProRes LT 4K = 33.1fps:

    H265_33_1_4K_fps.thumb.gif.508930a83e1bc

    This is on a 5+ year old MacPro: would be helpful to know performance numbers on other machines.

    Tried some NX1 files (80mbps 4K) with the same settings on my i7 3770 (4 cores 8 threads), 16GB RAM.

    I'm getting about 6.0 MB/s and 16 FPS when converting 4 files at once (I can't set Max Jobs higher than 4).
    It makes sense your 12 core machine is faster, but how come you get dubble the fps but the data rate is not that much different? Does that depend on the source files?

    When using RockyMountain Movie Converter (4K ProRes LT) it says it's working with a bitrate of around 275000 kbps. This translates to around 35MB/s. The 4 files (46 seconds in total) take about 90 seconds to convert.

    With Photon the same job is done in 68 seconds. The resulting files from Photon are a lot smaller though (600MB vs 1,5 GB for RMMC) with those settings.

    Also just noticed that the files from Photon have less contrast - RMMC seems to clip the blacks and whites where Photon still shows detail. Interesting, because the RMMC file looks the same as the original file when played back, but this might be another playback issue with contrast/blacklevels...

  7. @JFR: And switching to a C100 II is going to make that difference?

    The video by The Delivery Men you are showing is great. Is it great because it's shot on a C100? Would it be worse to watch when they had used a GH3 + Speed Booster? Maybe it would have a little more noise... who would care... it still would be awesome, because it has great production value. It's not the camera that makes it that good, it's the talent of a pretty big team:

  8. You have a speed booster, if you put the Sigma 18-35mm on it you get something close to 12mm, so I don't see the point of the 12mm f/2.0.

    Also, the 10mm is a dslr design. They do sell it with m43 mount, but it's still the same lens, just with a 'built in' adapter. That does make it a nice tight fit, but wouldn't it be preferable to get a Canon/Nikon mount version and put it on your speed booster? Then you can use it as a 7.1mm f/2.0. Not sure about the optical qualities though, haven't used them myself.

    edit: not sure if the 10mm will completely cover the GH3 sensor with a speed booster though, since it's an aps-c lens.

  9. Even a 4.3" 800x480 DP4 costs $599. How much money do they make on these things?

    I wish smartphones had video input options... I'm already walking around with a nice 5" 1080p screen...

    The SmallHD 502 on-camera monitor features a Full HD, 1920x1080 LCD display. With a pixel density greater than the iPhone 6 similar to any 5" Android smartphone in the price range of $300-500 that has been released the last few years.

     

  10. If only you could fit a speedbooster on there. Or maybe risk a slight vignette if you had the ability to adapt c-mount lenses. Anyone know of good lenses with the nx mount in 4k crop? Other than super telephoto?

    ​Sigma 8-16mm if you want very wide.
    Sigma 10-20mm if you want cheap wide angle (used less than $300)
    Tokina 11-20mm f/2.8 (or the previous 11-16mm 2.8) if you want wide + big aperture
    Samyang 12mm f/2.0 (comes in NX mount) 
     

     

  11. That's a very old image, showing the Nikon 1 V1 with some 'concept' accessories that never hit the market. Even though the V1/V2/V3 aren't targeted at soccermoms they lacked 24 and 25 fps options.

    This is a promo movie for the Nikon 1 J4, says enough ;) I wouldn't expect the 1 J5 will suddenly be aimed at filmmakers.

     

    The big question is WHY though. Nikon doesn't have to protect any film business.  When they introduced the Nikon 1 V1 in 2011, it would have been appealing as a small video camera if it had at least proper framerates.

    Technically speaking, Nikon could make killer video cameras in the 1 series. We've seen what people managed to do with the 30/60 fps raw burst. They just have to stick a huge buffer in it and give it a 24 fps raw option....
