(SINGAPORE, 8 April 2014) – Joining the acclaimed a7R family of the world’s smallest full-frame interchangeable lens cameras[1], Sony’s new a7S model puts extraordinary sensitivity, low noise and spectacular 4K video quality into the hands of professional photographers and videographers.

The innovative a7S camera features a newly developed, 12.2 effective megapixel 35mm full frame Exmor® CMOS sensor paired with a powerful BIONZ X image processor, allowing it to shoot at a sensitivity range of ISO 50 – 409,600[2] with unprecedented dynamic range and low noise.

The new model is also the world’s first camera to utilise the entire width of a full-frame image sensor in 4K video acquisition, and does this without cropping or line skipping as it can read and process data from every one of the sensor’s pixels. This allows 4K video shooters to utilise all of the artistic and creative benefits provided by the unique sensor.

Wide ISO Sensitivity (ISO 50 – 409,600)[SUP]2[/SUP] and Impressive Dynamic Range
Sony, the world’s largest manufacturer of image sensors[3], has developed a unique 12.2 MP sensor with extraordinary sensitivity that allows the a7S camera to collect dramatically more light than traditional cameras and to produce beautifully detailed, low-noise images in even the darkest environments.

The camera also features a newly developed on-sensor technology that allows it to optimise the dynamic range throughout the entirety of the ISO 50 – 409,600 sensitivity range. And this on-sensor technology also broadens the range of tonal gradation in bright environments while also minimising noise in dark scenes, allowing the camera to deliver impressive results in these extreme conditions where other cameras (and image sensors) typically struggle.

World’s First Full-Frame Camera with Full Pixel Read-out[4] (without pixel binning) during Movie Shooting
With the new a7S camera, the high-speed read out of the 35mm full-frame image sensor combined with the high-speed processing of the BIONZ X processor enables significant improvements in video quality.

These powerful components allow the camera to process data from all of the sensor’s pixels and output stunning HD and 4K (QFHD 3,840 x 2,160 pixels) video[SUP]4[/SUP] while utilising the full-width of the sensor. In addition to the benefits for low-light shooting, the read out of all pixels frees the video from aliasing, moiré and false color artifacts (as opposed to pixel binning) to achieve the highest quality video.

Additional Pro-Quality Video Functions
In video mode, the a7S can output 4K video[5] at QFHD (3,840 x 2,160)[6] to an optional external 4K compatible recorder, and can record full HD (1,920 x 1,080) at frame rates of 60p, 60i, 30p and 24p directly to a compatible memory card. Video modes can be changed from full-frame to APS-C (super 35mm equivalent) if desired, and in this crop mode, the camera can support high frame rate 120fps shooting at standard HD resolution (1,280 x 720p), creating a 5x slow-motion effect.

The a7S camera is also equipped with S-Log2 gamma. Common to Sony’s range of professional video cameras, S-Log2 expands the dynamic range by up to 1,300% to minimise clipped highlights and loss of detail in shadows. Additionally, for the first time ever in a Sony camera, the a7S adopts the workflow-friendly XAVC S recording format in addition to AVCHD and MP4 codecs. XAVC S format allows for full HD recording at a data rate of 50 mbps with lower compression for improved video quality.

Other specialist video functions on the new camera include a picture profile that can adjust settings like gamma, black, level and color adjustment, and can be saved for use in a multi-camera shoot. It also has Full HD and 4K base band HDMI® output, time code/user bit for easier editing, synchronous recording feature with compatible devices, various marker and zebra displays on both the LCD screen and viewfinder and can dual record XAVC S as well as MP4 (1,280 x 720 @ 30p).

The camera also has a Multi-terminal interface shoe that is compatible with Sony’s XLR Adaptor Microphone Kits (XLR-K1M plus a new model under development), allowing the use of professional microphone systems.

Low-light Shooting Advantages
The high ISO sensitivity range of the a7S camera is extremely effective for still image shooting, especially in low-light conditions, where the camera can shoot at high shutter speeds while keeping noise as low as possible. This is particularly useful for shooting indoor, dimly lit sporting events or other situations where most cameras typically struggle.

The camera is also equipped with the same high-precision Fast Intelligent AF system as the a7R camera, with drastically improved low-light AF sensitivity that can go as low as -4EV.

Expanding a Mount System and New Power Zoom Lens for Movie Shooting
Directly compatible with the growing family of E-mount lenses, the a7S camera can also be used with A-mount and others lens systems with optional adapters. Sony’s complete a lens system now includes 54 total lenses for both A and E mounts, including several premium offerings from Carl Zeiss® and G Series Lenses.

As a whole, Sony’s E-mount lens system is particularly well-suited for video shooting, with a variety of models containing “movie-friendly” features like smooth focusing, powered zoom control, and silent iris/aperture control. Building on this, Sony has announced development of a brand new, full-frame power zoom 28-135mm F4 lens E-mount lens that is an ideal match for the powerful movie capabilities of the a7S model.

No in build timelapse function?

Nowadays time lapse for Sony devices mostly is from the play memories s/w on the phone. Only thing is that hopes it does support and also, enough battery to run the apps.

Better than nothing but basic stuff like that should really be part of the initial firmware.

That's why I dare not to steps into E-mount till I have no choice. A-mount body, having the remote port, allows me to use 3rd device for time lapse. Some brands out there already have time lapse build in, wondering why Sony don't want to do so. :(

Yeah, works nicely on Nikon's bodies. The only reason not to build it into the firmware is to make some extra cash. I wouldn't be surprised when those features are actually already build in and the app just unlocks it like in some PlayStation games. ;)
 

The app just cost $10usd, much cheaper than any intervalometer, and has 10 "licenses" i.e. can install up to 10 different cameras which supports playmemories. Why are you guys complaning...

Not complaining la, just wondering. Ha ha! E-mount don't have grip for 2 batteries and time lapse on it, only can last a while. On top of it, thr wifi can drain the battery fast.

Wait for A7s pricing n whether any FF A-mount before August (launched) and then I decide what to get. I got no FE lens, need to put that into consideration if getting A7s.
 

not really, i assume most didn't really use/bought the timelapse.
vaguely remember my duration of 2 hrs of the timelapse took less than 30% of the overall battery power
 

I wonder the pricing will kill me or not :D

Agree. I can have a 999shot timelapse with less than a single charge. If you set display to viewfinder only and compose ur timelapse and just let it fire off, there will be no display as long as u dun trigger the evf sensor, and the batt consumption will essentially be the same as any dslr, which is to just activate the shutter periodically.
 

actually iirc viewfinder consume more power than lcd

no grip for 2 batteries???? huh??? there is the battery grip... what talking you?
 

This is more of a video cam with Photo taking function? I read that its 2.5FPS only. For 4K recording, seems that it does not record to SD card?

Not under nex series. A7 series then got grip but I invested too much on A-mount, hard to switch.
