    apefos got a reaction from GMaximus in An astounding Sony A7S low light test by Philip Bloom   
    about the "now i can see" video:

    unfortunately the dynamic range is very poor, and "now i cannot see",

    or better saying: now I can see the other side of the moon, but the first side is gone

    before a7s I had the good highlights and dark shadows
    now with the a7s I have the shadows but the lights are gone, blown out forever

    at 1:01 the carroussel is ok, but the faces are dark, more DR please.

    we need a camera which can merge the 1:15 image with the 1:20 image into an extended dynamic range image to show the lights without clipping and the sea together.

    at 1:58 I would like to see the buildings without clipping, more DR please...

    at 2:03 i would like to see the fire and face without clipping while lit the cigarrette, more DR please.

    just look at the 2:25 image. where are the buildings? more DR please.

    what about the 2:39 image? "total clipping of the heart"

    "total clipping of the heart"
    (Blowout Tiler)

    turn around every now and then
    I get a little DR and know I've got to get out and cry
    turn aound every now and then
    I get terrified about low light but then I can't see the sky

    turn around every now and then
    sony got my money but gave me a clipping background
    turn around every now and then
    I ask where is DR because it is so easy to increase the pixel count

    turn around bright eyes
    don't forget to see the dark parts
    turn around bright eyes
    don't forget to see the lights

    And i need more DR tonight
    An i need it more than ever
    and if DR is so tight
    we will be ML HDR forever

    and we'll only make it right
    when we have more dynamic range
    because the beach is bright
    but the background is so strange

    I really need you tonight
    HDR is a must tonight
    HDR is a must daylight

    Once upon a time there was a hidden dark face of the moon
    But now the bright face is blown away
    Nothing I can say
    A total clipping of the heart

    Once upon a time there was light in my life
    But now there's only sony in the dark
    Nothing I can see
    A total clipping of the heart

    OT: The video of music videos very rarely has any right of it's own. There are exceptions like Michel Gondry, David Fincher or Chris Cunningham.
     
    Here is a clip that exposes the ridiculousness of the typical music video's visuals, enjoy:

    apefos got a reaction from Brellivids in Sigma 0.71x aspherical focal recucer with ed glass   
    Sigma will enter the game of focal reducers for M43 and E-Mount.
     
    They will have an aspherical design, also using extra low dispersion glass to improve edge sharpness.
     
    The Sigma focal reducers will be 0.71x with 1 fstop increase in light.
     
    Will be available in main mounts: Canon FD, Canon EOS EF, Nikon F or G, M42, MC/MD, OM, PK, Leica R, Yashica/Contax
     
    Main problem of all focal reducers in market today is the edge blur, this is due to spherical lens design. Also some small amount of chromatic aberration is present. Sigma will solve these issues using aspherical lenses and extra low dispersion glass.
     
    This is a rumor.

    apefos got a reaction from maxotics in Surprise! Sony Alpha A6000 video mode huge improvement   
    Well... I downloaded the A6000 mts videos from Cameralabs review and the iso tests. Comparing to Nikon, to previous Sony NEX models and to Panasonic M43 cameras my conclusions are:

    The A6000 does not show aliasing which is pretty good.
    There is very small moire, not disturbing enough, possible to live with (I saw it in the beach shoot).
    The noise in high iso does not show chroma noise which is great.
    The noise in high iso is very fine and charming compared to previous NEX and to Panasonic.
    The iso up to 1600 does not need denoise.
    The iso 3200 is clean after denoise.
    The iso 6400 is clean after denoise with small trembling in shadows, not disturbing.
    The iso 12800 is not usable.
    The resolution is a little gross compared to Panasonic, Panasonic is more cinematic, razor sharp.
    If you want that razor sharp look which is desired to compete in tv broadcast and cinema theaters Panasonic M43 is the way to go, but the low light performance and E-mount with focal reducers allowing 1.16 crop factor is amazing on A6000.
    The gross in A6000 resolution is more perceived in wide shots showing buildings, in low light it is not annoying, but still much better resolution than Canon APS cameras.
    The resolution is on par with D5300 and I think A6000 is better because does not show halos in contrast edges. Low light is better than D5300.
    The highlights are recorded above 100 IRE and can be recovered in post production and this is amazing. There are textures and tonal range hidden in the cliped highligts, something like 1 fstop of dynamic range can be recovered in post, something like HTP in Canon cameras.
    The 5 levels of DRO to lift shadows combined with recovered highlights can deliver a great dynamic range.
    With a RJ lens turbo to increase light by 1 fstop and reduce crop factor this camera will be a new low budget Queen for low light and for use all kind of lenses. The 1.16 crop factor with the lens turbo just avoids the soft and dark corners from the full frame lenses.
    If you can record audio outside camera the A6000 is great for indie cinema. Also there is the option to buy the expensive bluetooth mic.
    I hope Sony give us mic input in A7000 and maybe S-Log2 in the A7000 also.
    The auto focus is accurate and smooth and does not show hunting, this is great.
    I like the A6000 a lot!
    I have the dream of Sony give us S-Log2 in the A7000 to increase dynamic range 1300%
    That's it.

    apefos got a reaction from john_d in Sony A7S specs announced - S for sensitivity. 4K via HDMI to "third party recorder"   
    What Canon needs to do now to compete is to release a version of EOS-M mirrorless with 3840 x 2560 sensor, 9.8 megapixel for photo and UHD video with same sensor technology from 70D, improved low light and dual pixel AF with the same log Dynamic Range as Sony did, recording UHD to the sd card or recording FHD. Price under 1000 usd.
    People wants to use all kind of lenses, not just proprietary lenses... so a expensive 4k 5D Mark IV would not be perfect for competition.

    apefos got a reaction from johnnymossville in Panasonic GH4 pricing official - $1698 body only, $1998 for the external 10bit / XLR box   
    For the GH5 Panasonic needs to develop a 4096 x 3072 native resolution sensor to allow the 4096 x 2160 video without horizontal crop in the micro four thirds sensor, better shallow dof, better wide angle and better low light due to increase in pixel size. Also it will be good for still photos because 4096 x 3072 is 12.6 megapixels, enough for most photo work. Dynamic range increase to reach ARRI is the most expected improvement in the Panasonic now... maybe this will be implemented in the organic sensor they are developing. And why not 200Mbps IPB in 4k?
