Low-light shootout: Nikon D4S vs. Sony A7S

In recent years, high ISO capabilities have moved to the forefront of many photographic discussions, and we’re even seeing some camera companies release cameras with a lower mega-pixel count in favor of higher ISO sensitivities. The Nikon D4S and Sony A7S are two prime examples of this, with both able to go up to an unprecedented ISO 409,600. But exactly how usable are these crazy ISO levels? We put the cameras to the test to find out.

    Thanks! We were using the A7S on FF mode, but it came with the 55mm f/1.8
    Zeiss while the D4S came with the 50mm f/1.4, hence a very slight
    difference in perspective. Glad you enjoyed the video!

    Nice comparison. What lens mode were you using on the a7s, FF or APS-C?

    Really informative video, keep up good work !
    I just want to know, how it auto focus speed on A7s. Especially in video

    of all tests I have seen, nikon is always sharper, but costs more, is
    heavier and you can always use nikon lenses or better on the sony. but the
    autofucus7startup/batterylife of the sony isn’t that good. I still got the
    sony. sony+ nice old lenses or kitlens for 900$ vs nikon without lenses
    for…how much? 4.000$ ?

    well you can buy 2.5 Sony A7s for the price of a Nikon D4s

    the Sony was using noise reduction in that video I believe. Too soft

    Nikon’s photos looked sharper

    Thanks for doing this comparison.
    The A7s is half the price of the D4s, and it shoots 4K video.
    In my opinion, Hands down, the Sony A7s is the winner and best value.

    This is quite possibly the poorest test I have ever seen as far as showing
    the difference between any two items being compared on the same thing…
    First off unless you are just absolutely horrendous at color correction you
    were wasting one of the largest added features of this camera, S-Log 2.
    Second when you adjust other values besides the ISO how can anyone get a
    grasp on the actual value of each said ISO.
    Third If you want to keep both of the light values the same for each camera
    you need to abandon manipulating the setting on camera, apart from ISO, and
    control these in post in whatever NLE you are using to create this video.

    This isn’t a ISO test it is a camera gain/noise test with so many
    fluctuating variables you are unable to make any kind of actual judgement
    on the evidence set before you as a viewer.

    I don´t really understand the use of this test. You were increasing the ISO
    and closing the aperture? We actually need to see what the camera can do in
    low light not closing the aperture and raising ISO, but raig the ISO when
    there is no more aperture left and still need more light to expose

    I haven’t yet found a video properly comparing the sony a7s and nikon d810
    against each other, specially the video capabilities, low light etc.

    Sony is better above 25.ooo isso.
    Good vídeo.
