    Is it going to be the same 2,5 MB/s rate for all different framerates and 2d/3d?
    For example there's quite a lot of more information in 3d 4k@48 fps compared to 2d 4k@24 fps (4x theoretically). On...

    There's a better quality version at Greg Williams's website: http://www.gregfoto.com/portfolio/image.php?album_id=43&album_item_id=727

    There's also one ad/short film and some stills from other...

    Probably stupid question but why would someone want to focus past infinity if the focus scale is calibrated (and the mount is collimated properly)?

    Best regards,

    And what about these?

    They call them Red One Primes which seems little suspicious as it looks like they got nothing to do with the Red Digital Cinema. The lenses only...

    Ron Fricke, watch out!
    The tracking shots from car(?) are really cool. Did you just drive really really slow? The motion control dolly shots are impressive too.

    What lenses did you use? I've done...

    I didn't say that either, I said 28.8mm width and used that in my calculations. I also said FF35 anamorphics which was maybe confusing and now when I think about it, I don't even know myself what...

    Hmm, I think this isn't quite so simple. If most anamorphic lenses cover 22mm * 18mm they would project an image circle with a diameter of at least sqrt(22^2 + 18^2) = 28.4mm. 22mm * 22mm area needs...

    Doesn't bayer pattern affect also vertical resolution? If bayer pattern reduces resolution by ratio of 3.2*1024 / 4096 = 0.8 then 'effective' resolution would be (3.2*1024) * (2304*0.8) = 6039798...

    Thanks for your explanation!
    So in this case analog gain allows to 'see more into the shadows', about the same amount that was clipped from highlights and so the dynamic range is almost same? Did I...

    analog vs. digital gain

    I think I understand how red one's iso rating and dynamic range work but I don't quite get it why dlsrs with analog gain have almost the same dynamic range with almost every iso-setting. E.g....

    adapter

    Since PL mount's flange-focal-depth is larger than canon EF-mount's woudn't a simple adapter work? Changing mounts sounds more diffucult that making an adapter and you could still use EF-lenses. Or...

    I have that same Manfrotto/Bogen video head and I'm surprised that you can use it with Red One, it doesn't feel that sturdy but if it works that's cool :)

    Ok, that's cool! Are there any 35mm motion picture film cameras that can use Leica M-lenses? Most of them propably have reflex mirrors which prevents using them. The fact that these lenses can be...
  14. leica m-mount lensmount-to-sensor distance

    Is Leica m-mount used in rangefinder cameras with no mirror-assembly?
    Since the lensmount-to-sensor distance for m-mount is 27,8 mm I'm surprised that m-lenses can be used with red one, even with...

    I'm surprised!

    I didn't realize Ari Koivunen was this known outside Finland, he's certainly popular here as he won the idols competition and his albums have topped the finnish charts.

    There is atleast one camera...

    Ok, I remember reading something about it. Do you know the reason for this? Is it just to get higher pixel count so they can advertise it as 12megapixel camera or are there some real benefits? On...

    What about vertical chroma resolution? As I know (and I don't know that much) Genesis has 2160 blue pixels vertically as Red One has 1152. Total number of blue pixels for Genesis is 1920*2160 = 4.1...
