Leaked German Press Release (Translated with Google Translate)

Note: This isn’t an official Sony press release leak, it’s a leak of a German press article covering the camera.

The heart of the new Alpha is a 12-megapixel full-frame sensor, which is compared to the Alpha 7S II was improved. Sony is now opting for a construction with back exposure (BSI), with which allows more light to be captured and enables better results in low-light shots. The maximum sensitivity is still ISO 409.600 (expandable down to up to ISO 40). The sensor is supported by the new BIONZ-XR processor, which is eight times as much
Should have computing power, like the previous image processor.

Sony also works with the operation new ways: For the first time in the Alpha 7 series, a fully movable monitor (3.0 inches, 1.44 million Points), which now also allows touch operation of the menus. The structure of the menus has also been completely revised; among other things, stand in photo and video mode for one better clarity only the relevant entries are available. A record break The OLED viewfinder achieved 9.44 million points and a magnification of 0.9x. In order to even glasses wearers have the entire picture in view, the size of the picture can also be reduced.

4K with 120p.
One focus of the camera is video recording. Unlike Canon sets with the EOS R5 Sony for video not on 8K, but further on 4K, but the best results so far with one Alpha camera should achieve. The sensor’s 12 MP resolution enables a full pixel readout without pixel binning and without crop up to 4K / 60p. The admission limit should be in this setting an hour without overheating – the EOS R5 manages at 4K / 60p only 30 minutes at a time. This is the length of the video recording in the Alpha 7S III 4K / 120p limited – by the way, a slight crop is used (1.1x).

The monitor can be swiveled, and the handle and controls are – like other cameras – the third Alpha generation – got bigger.

Sony With Full HD, the Alpha 7S III even records at up to 240p. For time-lapse recordings, you can S&Q mode also lower frame rates up to 1p can be selected. It is recorded internally a color subsampling of 4: 2: 2 and a color depth of 10 bits. New codecs are available Available: XAVC-S-I records single images (All-I) with a data rate of up to 500 Mbits / s, XAVC-HS reduces the amount of data for image group compression thanks to H.265 compression to 200 Mbit / s. With HDMI 2.1, the camera can even handle 4K / 60p as 16-bit raw files (ProRes Raw) to an Atomos recorder. Of course there is also a logarithmic one Gamma profile available (S-Log 2/3), which has a dynamic range of over 15 f-stops should enable; the sensitivity starts here at ISO 640 (extended: ISO 160).

Clear According to Sony, it has minimized the rolling shutter effect. The Alpha 7S III is included a 5-axis image stabilizer in the housing, measured according to the CIPA standard achieved an effectiveness of 5.5 f-stops; in video mode there is also a digital one Stabilization (Active Mode) is used, which also uses a gyro sensor. The information This gyro sensor can also be stored in the metadata of the videos to be used in the Use post-processing for digital stabilization.Fast autofocus and 10 frames / s The hybrid autofocus covers 92% of the image sensor and uses 759 measuring fields Phase detection and 425 with contrast AF.

In addition to human, the AF algorithms recognize now also animal eyes – according to Sony, also at a greater distance than before. The AF sensitivity goes up to -6 EV series, the camera shoots at up to 10 frames / s. The mechanical closure is designed for 1/8000 s.

For the first time, Sony uses two memory card drives in the Alpha 7S III, both SD cards (UHS-II) as well as the new CFexpress Type A cards. They are smaller than that Type B cards and faster than SD cards. For most video modes, SD cards are sufficient Video classes V60 and V90, only in S&Q mode with 4: 2: 2 color subsampling and 10 bits Color depth is required for CFexpress. The series mode also benefits from the faster cards; 1000 uncompressed raws in a row should be possible here. Sony wants two in September Launch CFexpress Type A cards with a write speed of 700MB / s and have a reading speed of 800 MB / s: The 80 GB variant should be 230 euros, the 160 GB version costs 440 euros and supplies electricity for 600 photos or 95 minutes of video.

A Z battery is used for the power supply, which can be charged via USB-C and power for 600 photos or 95 minutes of video. Continuous power supply via USB is also possible. The Sony Alpha 7S III should be available in September for around 4200 euros.
