| Sony announces the A7S III Camera |
Sony introduced the A7S III camera after its predecessor A7S Mark II focused on video for five years.
The A7S series was first introduced in Allergy S mode in 2014, while A7S II was launched in 2015.
Both cameras use a 12-megapixel full-frame sensor to monitor dynamic range and performance in low-light conditions.
Many users have already benefited from video performance, which is increasing demand for cameras.
With the new camera, Sony not only provides the required video functionality, but also improves light and dynamic ranges.
The A7S III has a 12-megapixel backlight sensor EXMOR R CMOS.
The sensor combines a relatively low resolution and a relatively large sensor size, which makes the camera very good in low-light conditions.
There is also a new image processor (BIONZ XR) that has 8 times the processing power of the processor (A7S II).
The camera's ISO range is between 40 and 409,600 and the dynamic range is over 15 apertures.
The camera can take 10 frames per second in continuous shooting mode, but the cache is very large, so you can capture up to 1000 uncompressed and continuous shooting (RAW) with AF tracking and fully auto exposure.
The A7S III can also capture HEIF (10-bit) images with wide dynamic range (HLG).
With video specifications, the camera can offer up to 4K resolutions at 120 fps, and recording is completely internal.
By connecting the camera to an HDMI (full size) connection, 4K video can be recorded externally at 60fps.
Thanks to Sony, the camera can record up to an hour of video continuously without overheating thanks to the new internal cooling system.
Compared to other video cameras, this camera supports color profiles (S-Gamut), (S-Gamut 3), and (S-Gamut3.Cine) to enhance coloring.
There is also a new format (XAVC HS) with codec (H.265) for improved efficiency, and unlimited recording time.
Sony added a new focus system to process videos and still photos that use the new phase detection autofocus (759 points) that can cover 92% of the image sensor.
(A7S III) contains five-axis stabilizer that is best suited for IBIS lenses, but is particularly suitable for unstable lenses.
Sony has also incorporated a 3-inch touch screen into the new camera (first in the A7 series).
Sony has fully updated the touch user interface. With the touch screen, you can now select and scroll menus.
The camera features a design with two card slots and can accommodate (UHS-II SD) or (CFexpress) cards in each slot.
You can take videos or pictures at both locations at the same time, or switch cards in sequential mode while recording the camera to the other card.
Sony said: Compared to the A7S II battery, the camera battery recording time is 60% longer.
According to Sony, the A7S III costs $ 3,500. Sales begin in September.
