Sony is the one name that has made a real mark in the world of digital photography. The company has been successfully tried out different concepts in cameras. They have been able to provide SLRs with dual autofocus systems as well as Translucent Mirror Technology to the NEX 7 as well as Alpha 7R series. The most exciting products until now are the Alpha 7R and the NEX7. Full frame cameras were successfully provided to its customers till the date. With the arrival of Alpha7s a smaller version of the full frame interchangeable lens peers has come up in the market. This can be termed as an achievement, since these are not SLRs.
Apart from this, Sony has tried to blend the brands NEX and Alpha. In short, every interchangeable lens cameras in the coming years will come under the Alpha series. The major peculiarity of Sony A7 is that it is a mirror less camera.
The external design of A7s is similar to that of A7 and A7R. It is being introduced to the market as the first 4K Video capable still camera. A7s has a low resolution full frame 12 megapixel sensors, that makes it stand apart from A7 and A7R. This can be called the right resolution for a camera.
The s in A7s stands for Sensitivity. With the 12.2 megapixel full frame sensor limiting the downscaling with 3, 840 x 2, 160 (QFHD) 4K video, providing the perfect quality shot. You are able to store 1080p video internally. But you might need an external recorder for the purpose of capturing 4K video. The camera will output the video with a 4:2:2 color sampling through HDMI.
With the help of a class 10 or a larger SDXC card, you will be able to store XAVC S format video. With the mode 1080p, you will be able to shoot with the APS C cropping. When you shift to 720p, you get the 120 fps capture. The image quality of stills is extremely high. But the real attraction of this model comes while capturing 4k as well as HD video. Reduced shadow and clipping highlight is possible with this model, since the camera supports S-Log2 gamma that expands the dynamic range to 1300 percent.
The solid sturdy design of A7s also contains Wi-Fi as well as NFC which is suitable for transferring image and video files to your tablet of Smartphone. Similar to other Alpha 7 cameras, A7 too has multi interface shoe. This can provide the XLR audio input through the XLR- KIM adapter kit.
