An Overview

Since its release in 2013, the Sony a7S has become an instant favorite among photographers and non-photographers.

Therefore, you can quickly get a detailed picture and fewer image artifacts in a7s than higher-megapixel cameras. The a7S camera is loaded with valuable features.

Features and Specifications

Let’s discuss a few of the main aspects of the Sony a7S camera to fully understand how having this gadget will be a good investment for you.

In addition, the Sony a7S’s WhiteMagic technology enhances brightness for better viewing in sunlit conditions. To shoot at eye level, its 0.5’’ XGA OLED electronic viewfinder utilizes 2.36 million dot resolution and 0.71x magnification to ensure precise monitoring capabilities. 

BIONZ X Image Processor and Exmore Sensor

The BIONZ X image processor and 12.2 MP full-frame Exmor CMOS sensor of the Sony a7S work together, enabling an expansive range with notable sensitivity and minimal noise. Sony a7S has a native sensitivity range from ISO 100 to 102400, which is perfect for working in low-light conditions. 

The sensor of Sony a7S also comes with a new-generation RGB color filter array and a gapless on-chip-less design. These two technologies ensure efficient light-gathering capabilities to reinforce high-sensitivity and low-noise design. The anti-reflective coating on the seal glass of the image sensor decreases glare and surface reflections, ensuring color-neutral and contrast-rich imagery. The effective combination of BIONZ X Image Processor and Exmore Sensor in Sony a7S adds many performance-related benefits.

Hence, whether you record externally in 4K or internally at 1080p, you are bound to see a sharp image devoid of major aliasing and moire. Therefore, the Sony a7s 4k recording is impressive.

For example, if the high-quality 50 Mbpa XAVC S Codec is not enough, the Sony a7S has the option of uncompressing UHD 4K at 4:2”2 color depth over HDMI. This feature makes Sony a7S 4K recording easy and efficient.

High-Speed Video Recording
