Sony A7S Mk III 4K DSLR Camera

The performance of the A7s is indeed impressive, as are the pictures from it.

A 12.1 MP 35mm full-frame Exmor CMOS sensor, a 7.5cm (3.0-type) type TFT tilting LCD monitor, an 1.3 cm (0.5 type) XGA OLED electronic viewfinder (color) , Sony’s BIONZ X image processor, fast intelligent 693 points (phase-detection AF), NFC, WiFi and 4K and Full HD video recording in XAVC S.

This camera system is provided with a Shape camera cage as part of the standard package.

Lens Mount

This camera has a native Sony E mount mount and VMI supplies a Metabones electronic EF adapter as standard with this camera, so that you can use EF autofocus lenses.

Note that this camera can mount directly to APS-C (Sony E Mount Lenses) without using any adapter.

You can still use Super 35mm APS-C size and use cinema lenses, or indeed full-frame stills lenses with Metabone Speedboosters (provided you are shooting in APS-C format).

An optional PL lens adapter is available at additional charge.

Video Capability

It is only fair to advise that whilst the still pictures are superb, moving images are susceptible to jelloing (bending vertical lines). Although the Sony A7SIII has 3 x less “jelloing” than it predecessor the A7SII.

The camera is capable of performing 4K internal recording with 10-bit depth and 4:2:2 colour sampling when using either Long GOP or All Intra compression. This makes it possible to push your colour grades further, stretching video out for ultimate HDR realism while still retaining natural gradation, for true editing freedom.

The α7S supports high frame rate shooting at 120fps or 100fps at 4K. The 120fps footage can be played back at 24p for a 5x slow-motion effect – ideal for seeing every detail of sports action. Professional videographers will also benefit from features such as Picture Profile™ for wide ranging visual expression and S-Log2 gamma.

4K 10 bit 4:2:2 On Board Record Now

The Sony A7S III is also capable of internal UHD 4K recording at 120P with full pixel readout in the XAVC S format. For both stills and video recording.

3840 x 2160 (4:2:2, 10bit, PAL) (Approx.): 100p (280Mbps), 50p (200Mbps), 25p (140Mbps)

Timecode / user bit functions allow pro-style editing workflow, while an optional XLR Adaptor Microphone Kit supports high-quality audio acquisition.

• 4k video output on HDMI
• For fantastic 4K recording and monitoring, pair the A7S with the Odyssey 7Q+ (not 7Q) or Atomos Shogun 4K
• ISO RANGE

Standard – Still = 100 – 102400, Movie = 200 – 102400
Expandable – Still = 50 – 409600, Movie = 200- 409600
Some crazy ISO numbers there and amazingly a lot of them are actually usable.

FRAME RATES
HD = 1fps,2fps,3fps,6fps,12fps,25fps,50fps,100fps, 200fps
4K = 1fps,2fps,3fps,6fps,12fps,25fps,50fps,100fps,

Features

• 24.2MP APS-C CMOS sensor
• 8 frames per second continuous shooting
• 1080p HD video recording with manual controls
• 3.0 inch Clear View II LCD screen with 920,000 dots
• 19-point AF system (all cross-type)
• 1.0x magnification and 100% coverage viewfinder
• Wireless flash control

In summary, it shoots very good 4K video on board with the same full-size sensor as a 5D Mk III.

Essential Accessories

Also, if you want to use Canon EF lenses, be sure to hire a Metabones E Mount to EF Speedbooster  to fit EF mount lenses with full autofocus capability instead of the regular metabones or PL mount instead.

An optional K6/ME66 Gun Mic and Headphone package is available at £12 per day including boom pole & cables in a single case.
