Sony ALPHA S7 (a camera that sees in the dark)
With the Alpha 7S, Sony has presented a full-format camera with the incredible ability to capture images with ISO 409.600 and film in 4K. Some beauty errors in the operation provide for detuning, especially since the system camera with a recommendable lens costs over 3,200 euros.
The Sony 7S is the third model of the A7 series – and with the lowest sensor resolution, although the image converter is as big as a slide. Only 12 megapixel images can be taken with the small and very light camera, but this limitation is more than offset by the maximum light sensitivity of ISO 409.600. No other system camera can operate in this area, and the Sony 7S can still film.
HDTV is only possible with HDTVs, but an external HDMI recorder can achieve resolutions of 4K (3.840 x 2.160 pixels). Unfortunately, the camera has no support for 4K with 4,096 x 2,160 pixels, which in some situations would have made it interesting for professionals, since it is very light. In addition to XAVC S can also be filmed in AVCHD, MPEG-4 and AVC / H.264, whereby the highest quality is achieved with XAVC S, with which Full HD with 60p, 30p and 24p at 50 Mbps can be recorded. Video can also be filmed through it in 1.280 x 720 pixels at 120p / 50 Mbit / s.
Of course, the highest ISO value is more useful for the recording than for the actual shots, but up to ISO 51.600 the picture material can be seen which a huge amount is. The assessment is valid for both film and photo shoots.
