Sony Alpha 7S III + SEL FE 20-70mm f4 G

Sony Alpha 7S III

The sensor of the Alpha 7S III resolves 12 megapixels, as in the Alpha 7S II, but is now rear-exposed

heart of the new Alpha is a 12-megapixel full-frame sensor that has been improved over the Alpha 7S II. Sony now relies on a backside exposed (BSI) design, which allows more light to be captured and gives better results in low-light shooting. The maximum sensitivity is still ISO 409,600 (expandable down to ISO 40).

sensor is supported by the new BIONZ-XR processor, which is said to have eight times the processing power of the previous image processor.

Sony is also breaking new ground in terms of operation: for the first time in the Alpha 7 series, a fully movable monitor (3.0 inches, 1.44 million dots) has been installed, which now also allows touch operation of the menus

.

The structure of the menus has also been completely revised; among other things, only the relevant entries are available in photo and video mode for better clarity. The OLED viewfinder achieves a record resolution of 9.44 million dots and a magnification of 0.9x.

size of the image can also be reduced so that eyeglass wearers can also see the entire image.

4K with 120p
One focus of the camera is video recording

.

Unlike Canon on the EOS R5, Sony doesn't rely on 8K for video, but continues to rely on 4K, which is, however, said to produce the best results yet on an Alpha camera. The sensor's 12MP resolution allows for full-pixel readout without pixel binning or cropping up to 4K/60p, and

the recording limit is said to be one hour at this setting without overheating - the EOS R5 can only manage 30 minutes at a time at 4K/60p

.

Video recording is limited to this length on the Alpha 7S III in 4K/120p mode - by the way, this is also where a slight crop kicks in (1.1x).

monitor can be tilted, and the grip and controls have become larger - as in other cameras of the third Alpha generation.

In Full HD, the Alpha 7S III even records at up to 240p. For time-lapse recordings, lower frame rates of up to 1p can also be selected in S&Q mode. Recording is done internally with a color subsampling of 4:2:2 and a color depth of 10 bit. New codecs are available for this: XAVC-S-I records single frames (All-I) at a data rate of up to 500 Mbits/s, XAVC-HS reduces the amount of data during image group compression to 200 Mbits/s thanks to H.265 compression. Via HDMI 2.1, the camera can even output 4K/60p as 16-bit raw files (ProRes Raw) to an Atomos recorder.

Of course, a logarithmic gamma profile is also available (S-Log 2/3), which is supposed to enable a dynamic range of over 15 f-stops; the sensitivity here starts at ISO 640 (extended: ISO 160)

.

According to Sony, the rolling shutter effect has been significantly minimized. The

Alpha 7S III is equipped with a 5-axis image stabilizer in the housing, which achieves an effectiveness of 5.5 f-stops measured according to the CIPA standard; in video mode, a digital stabilization (Active Mode) is also used, which also uses a gyro sensor

information from this gyro sensor can also be stored in the metadata of the videos to be used for digital stabilization in post-processing.

Fast autofocus and 10 fps
The hybrid autofocus covers 92% of the image sensor and uses 759 measuring points with phase detection and 425 with contrast AF. In addition to human eyes, the AF algorithms now also recognize animal eyes - even at a greater distance than before, according to Sony. The

AF sensitivity goes down to -6 EV

.

The camera shoots series at up to 10 fps. The mechanical shutter is designed for 1/8000 s. Sony uses two memory card drives for the first time in the Alpha 7S III, which can use SD cards (UHS-II) as well as the new CFexpress Type A cards. These are smaller than Type B cards and faster than SD cards. SD cards of the video classes V60 and V90 are sufficient for most video modes; only the S&Q mode with 4:2:2 color subsampling and 10-bit color depth requires CFexpress.

mode also benefits from the faster cards; 1000 uncompressed raws in a row should be possible here.

Z-battery is used for the power supply, which can be charged via USB-C and supplies power for 600 photos or 95 minutes of video. Continuous power via USB is also possible.

Sony SEL FE 20-70mm f4 G

The advanced optical design of the SEL2070G full-frame lens from Sony includes four ED (Extra Low Dispersion, one of which is aspherical) elements, two AA (Advanced Aspherical) elements, and one normal aspherical element to ensure outstanding resolution. The 9-blade circular aperture provides particularly soft background blur (bokeh), and

two complex XD (Extreme Dynamic) linear motors enable faster and more accurate focusing when shooting video and stills. The

SEL2070G is especially optimized for video

.

It offers smooth, fast and precise autofocus performance even when shooting video, and features minimized focus breathing as well as focus shift and axis shift when Zooming.

Incredibly sharp
Four ED (Extra Low Dispersion, one of which is aspherical), two AA (Advanced Aspherical) elements, and one normal aspherical element ensure outstanding resolution all the way to the edge of the frame, and beautiful bokeh makes this outstanding full-frame lens ideal for content creation, still photography, and video shooting

Wonderfully soft background
Thanks to a 9-blade circular aperture, this 20-70mm G lens from Sony creates beautiful bokeh effects with background blur at a constant F4 a

Fast and accurate autofocus
Two complex XD (Extreme Dynamic) linear motors enable faster and more accurate focusing when shooting video and stills. You'll never miss a shot with this ultra-wide-angle lens including standard Zoom.

Brightness regardless of weather
A constant maximum F4 aperture throughout the Zoom range ensures consistent brightness even as the focal length changes. The front element of this Sony G lens features a fluorine coating that repels water, oil, and other contaminants. This makes it easy to wipe away dust and fingerprints.

Professional Ergonomics
A dust- and water-resistant design and versatile controls make this G Lens from Sony the ideal companion for even the most demanding situations - indoors and out. Plus, this ultra-wide-angle standard Zoom lens is compatible with Focus Breathing Compensation.

Forward-thinking
With Sony Lenses, you can also make the most of the features of your next Sony Camera in the best possible way
