Sony has announced yet another update to its popular a7 line of full-frame mirrorless cameras. The sixth generation a7S II includes a trio of key features that set the camera apart from earlier models.

For starters, the a7S II is able to natively capture 4K video with full pixel readout and no pixel binning in full-frame format at up to 100Mbps. If you recall, last year’s a7S could technically shoot 4K video but it required an external recorder.

Also new this year is a five-axis image stabilization system that minimizes camera shake along five axes during shooting: yaw, pitch, vertical shift, horizontal shift and rolling. The same system is found in the a7 II and a7R II and if it’s anywhere near as good as Olympus’ implementation, it’ll make a huge difference when it comes to low-light shooting.

Another aspect that’s sure to improve low-light performance is the camera’s incredible ISO range of 50 to 409,600. Again, this is a carryover from earlier models although Sony said it has upgraded the image processing algorithm used by its BIONZ X image processing engine for even greater performance in low light.

Some may be disappointed that the camera uses the same 12.2-megapixel full-frame Exmor CMOS sensor as its predecessor. If you know anything about photography, you’re probably aware that megapixel count doesn’t mean a whole lot. In this instance, Sony went with a lower megapixel count so that each pixel on the sensor can be larger and more sensitive.

The Sony a7S II will be available starting next month in the US priced at $2,999 (body only).
