Sony A7S II
The Sony A7S II is an improved version of the Sony A7S. It comes with a new body, improved autofocus and is capable of full frame mirror less camera. It is carefully designed with a 12.2 megapixels sensor with an ISO range of 100 to 102,400. It utilizes the Sony‘s 5 axis mage stabilizer which provides up to 4.5 stops during vibration reduction. This camera is great when shooting in low light modes as the images produced will be of high quality.
The technical aspects of the camera include a 12.2 megapixel full frame CMOS sensor, a BIONZ X image processor, fast intelligent AF with 169 auto focus points, internal UHD 4K30 with 1080p at a 20 mbps recording, 5 axis steady shot inside stabilization, a 3.0 inch 1,228,800 dot LCD screen which can be tilted and an built-I wifi and NFC system for connectivity.
The aspect ratio is of 3:2 or 16:9. The bit depth of the camera is 14 bits with a maximum resolution of 4240 by 2832.
It records still images using the JPEG and RAW formats while videos are recording using the MPEG-4 AVC/H.264, AVCHD2.0 , MP4 and XAVC S formats.
This Sony A7S II model is similar in appearance to the A7R II model. It has a lock mode dial, relocated front control dial, shutter release button and a hand grip that is re-countered. The body consists of an all rounded beefier and strong magnesium body with the lens mounted on it.
Under the hood of the camera is the CMOS sensor with 12.2 megapixels and an impressive image stabilizer which is effective for both video and still images. Capturing of images in low light is made possible by the camera’s high ISO and the steady shot inside system which provides a4.5 stop of correction. Furthermore, image quality and detail is enhanced by the BIONZ X processor with tweaked processing algorithms.
The Sony A7S II is full framed with 4K recording. This makes recording of videos very simple and also shooting on the go with 4K UHD. One should note that this camera does not offer cinema 4K support that is 4096 by 2160 video resolution.
Its ultra video HD uses the full pixel readout of the full frame sensor. It also allows for a clean and simultaneous HDMI output of up to 4K 4:2:2 signal while still recording up to 4K XAVC S video.
Improvements on this camera include a cinema oriented picture profile which gives the camera 14 stops of dynamic ranges with 1300% for greater grading and smoother gradation in between highlights and shadows. The new gamma display assist function of the camera provides a stronger and more natural contrast on the camera’s LCD screen while recording video with the S-log2 or S-log3image profiles. The camera also has an improved and more adjustable zebra function when one is shooting in the flatter gamma picture profiles.
The camera has full HD video recording of up to 60p at 50 Mbps while in XAVC S mode. For highly detailed videos, the full width of the full frame processor is used which records at 1080/120p frame rates for both 100mbps and 60mbpsfor better slow motion effects.
The autofocus is improved for both still and video capturing with a total of 169 AF points for better precision and accuracy. This also makes it to be twice as fast during video recording. The AF system in majorly of contrast detect and not hybrid AF system. The autofocus functionality is maintained at -4EV considering the low noise capabilities.
The enhanced autofocus modes consist of an enhanced eye AF which is capable of tracking a moving object’s eye in the frame. The expand flexible mode of the camera gives the helper AF point in case the subject moves out from behind the main AF point.
The Sony A7S II has an electronic viewfinder with a 0.78x magnification. The EVF has a new four lens construction which includes a Zeiss T coating and double sided aspherical elements. These help to ensure minimal surface reflection and crisp image resolution.
The shutter mechanism of the camera is built to withstand over 500,000 actuations. Its shutter braking system reduces shutter vibrations due to the mechanical front and rear curtains. The silent shooting mode provides a completely silent operation with the electronic shutter. This can be used together with the 5 frames per second speed priority continuous burst shooting mode.
The camera also has a built-in wifi and NFC connectivity which allow for remote control and sharing of media. In addition to this, the camera supports play memories lines of camera app installations which allow users to add extra camera functionality through special effects and time lapse.
The advantages of this camera include a built-in stabilization, improved performance in low light areas, a wider range of ISO, excellent video outputs and a stunning autofocus.
The limitations of the Sony A7S II include the fact that it lacks a built-in flash, has a low resolution and has a lossless compression when shooting in the RAW format.
