Sony Cashback - £200
The Sony Alpha A7s full-frame digital camera combines a 12.2MP full-frame CMOS sensor with Sony's powerful BIONZ X image processor to deliver unrivalled sensitivity and exceptional low light performance. Designed to meet the needs of the serious photographer and videographer, the A7s (‘s' stands for sensitivity) offers an ISO range up to 102,400, which is expandable to 409,600, and the option to output 4K video to an optional recorder through its HDMI port, without the need for line skipping or pixel binning. Further to the above, it delivers Full HD 1080p recording, Wi-Fi/NFC connectivity, a fast 25-point contrast-detection AF system, a 2.36 million-dot XGA OLED Tru-Finder and a 3.0" 921.6k-dot tiltable LCD monitor.

12.2 MP 35mm full frame sensor
The a7s combines phenomenal sensitivity - ranging from ISO 50 to 409600 for still images and ISO 200 to 409600 for movies with supremely low noise, courtesy of Sony’s new 12.2-megapixel 35mm full-frame Exmor CMOS image sensor and optimised high-speed BIONZ X image processing engine. Professional movie functions satisfy the highest demands of serious photographers and videographers, and it’s all packed in the world’s smallest 35mm full-frame interchangeable-lens camera body.
Ultra-high sensitivity up to ISO 409600
Expand your still and movie capabilities with the ultra-high sensitivity range from ISO 50 to 409600 for still images and ISO 200 to 409600 for movies.
BIONZ X processor
Sony proudly introduces the new BIONZ X image processing engine, which faithfully reproduces textures and details in real time, as seen by the naked eye, via extra high-speed processing capabilities. Together with front-end LSI (large scale integration) that accelerates processing in the earliest stages, it enables more natural details, more realistic images, richer tonal gradations and lower noise whether you shoot still images or movies.
Clean HDMI output for 4K movies
Non-compressed image output is now possible at 4K (QFHD; 3840 x 2160 pixels) resolution with selectable 30p and 24p frame rates. You can choose 4K or Full HD output from a menu. The 4K output capability allows recording of high-quality 4K images by a 4K-compatible recorder, as well as 4K output directly to a compatible monitor or TV.
Multiple recording formats
The a7s records in a wide variety of formats convenient for photographers working at all professional levels. It is compatible with 4K 24p, 30p/Full HD 60p, 60i, 30p, 24p video output and Full-Frame & APS-C (Super 35mm equivalent) size.
Portable moviemaking reaches a new level of flexibility and attainability with the a7s’s unique combination of 35mm full-frame sensor, audio production features, and flexible lens interchangeability. Now, the dramatic effect of beautiful bokeh, plus the artistic choice of creating a rich cinematic ambience is yours, thanks to the full frame, P/A/S/M mode, and advanced audio capabilities. The accelerated BIONZ X image-processing engine enables area-specific noise reduction and detail reproduction technology to be applied to movies, resulting in ultra-fine detail and exceptionally low noise. Features like Picture Effect, full HDMI output for an external monitor, and full 1080p AVCHD Progressive format plus XAVC S, and the choice of 60p/24p recording further expand the options.
XAVC S format
The high-bit-rate XAVC S format is provided for serious videographers. Available for the first time in an a camera, it enables Full HD image recording at 50Mbps for extremely high-quality expression and minimal noise. It also employs the Long GOP (Group of Pictures) data compression method to realize efficient movie recording. Note: Sony recommends using an SDXC memory card higher than Class 10 when shooting movies in the XAVC S format.
S-Log2 gamma setting
This proprietary Sony gamma setting, featured in commercial video equipment, creates a 1,300% wider dynamic range for smooth expression of gradation with reduced whiteout and blackout. Through color grading in post production, you can make the most of the low-noise image and super-rich detail to achieve various types of image expression.
Time code / User bit
As with commercial video equipment, this function provides a "Record Run" setting that only advances the time code while recording, a "Free Run" setting that advances the time code whether recording or not, a drop frame method and a non- drop frame method. The a7s can also output a superimposed time code when the clean HDMI output setting is in use. Note: This function is only available when recording in the AVCHD and XAVC S formats.
120fps shooting at HD resolution
When shooting movies in the APS-C (Super 35mm equivalent) crop mode, the a7s supports high-frame-rate 120fps shooting at HD resolution (1280 x 720 pixels). This remarkable capability broadens image expression options since a movie shot at this frame rate can be played back at 24p to create stunning 5x slow-motion effects.
You can fine-tune the look of movies before shooting by adjusting gradation (black level, gamma and black gamma), color adjustment (color mode, intensity, color tone and depth), basic color (gamma and color mode) and more. Adjusted parameters can be saved along with other settings as a profile, and up to seven profiles can be stored for later recall.
Anti-dust system and coating
To keep your photos blemish free, an anti-dust mechanism vibrates ultrasonically whenever you switch off the camera to remove any particles adhering to the image sensor. An anti-static coating also helps prevent dust and other particles from adhering to the sensor when changing lenses.
XGA OLED Tru-Finder
This viewfinder features high 1024x768 resolution, OLED improvements and the same 3-lens optical system used in the flagship a99 despite the compact body. The viewfinder displays the effects of your camera settings, so you can accurately monitor the results. You'll enjoy rich tonal gradations and three times the contrast of the a99. High-end features like 100% frame coverage, wide viewing angle, information display modes, peaking function, and focus magnifier are also provided.
Enhanced Fast Hybrid Autofocus
Numerous features contribute to the Diamond's autofocus capabilities: the new lightning-fast BIONZ X, high-speed full-frame image sensor output, and a newly developed Spatial Object Detection AF algorithm that conducts focusing analysis in real-time using spatial frequency information to optimally control the lens drive.
Audio recording & monitoring
During movie recording and playback, you can monitor the sound using headphones connected to the a7s via the headphone jack, check levels with the display controls, or attach professional sound gear using the industry-standard XLR terminal adaptor kit.
Tiltable LCD screen
7.5 cm, 1.2 million dot LCD offers high resolution and flexible composition options
Magnesium alloy body
Thanks to this outstandingly light and strong metal, the a7s weighs 489 grams with battery - less than half the weight of leading DSLRs - but has the durability for years of performance.
Substantial, ergonomic grip
The Diamond is 25% less bulky than leading DSLRs, but still features a full-size grip for all-day shooting comfort.
Dust and moisture resistance
Durability-enhancing measures include sealing around the buttons and dials, as well as a protective double-layered structure that tightly interlocks panels and components.
Controls, customisation and navigation
Despite compact dimensions, the a7s features front and rear dials for intuitive setting of exposure, a control wheel for setting ISO, and an exposure compensation dial. Quick Navi Pro displays all major shooting options on the LCD screen so you can rapidly confirm settings and make adjustments as desired without searching through dedicated menus. Button customization empowers you to shoot just the way you like, with frequently used functions assigned to the customizable buttons of your choice. You can easily assign various functions to any of 9 buttons; and selected key functions can be assigned to the Fn button for quick access.
