Major Video Announcement: Sony unleashes the Sony Alpha a7RII with 4k video

by Bret HoyLeave a Comment

Sony has just released details regarding the follow-up to their 36 megapixel a7R called the Sony Alpha a7RII (pre-order at b&h). The updates are many and impressive.

Petapixel reports that at the core of the new camera is a Full Frame, back-illuminated 42.4 megapixel CMOS sensor that has light sensitivity up to 102400 ISO. (Check out previous post regarding its rumored 50 megapixel sensor) Similar, yet not as sensitive as the a7S, however included is a heavily increased Autofocus system that sports 399 phase detection AF points and 25 contrast points.

This mean that autofocus response time has been increased by 40%. No word yet on the FPS for shooting Raw or JPEG, however the data processing speed is 3.5x faster than the original.

The a7II’s 5-axis sensor stabilization is also in the Sony a7R II.

The biggest surprise about the Sony A7r Mk II are the enhanced video capabilities. The a7R II has been upgraded to shoot 4K in, “multiple formats” and 120fps at 720. It is unclear at this point whether this is a cropped APS-C capture, like the a7S. It is also unclear what is capable externally through the clean HDMI out.

The cherry on top of this huge announcement cupcake is the body upgrade. The Sony a7R II now has the same Magnesium Alloy body that the a7II uses.

Why is this such a big announcement?

Apart from Sony’s inclusion of so many fantastic elements from the other bodies in the a7 series, it’s the progress that’s been displayed by Sony in the past couple of years that has me excited. Instead of limiting their cameras to being, “the photo a7” (a7R) or, “the video a7” (a7S) they’ve coalesced the greatest parts of each one into a body that’s truly pushing the envelope.

This announcement also foreshadows the inevitable announcement of the a7S II. Sony have given us a lot to be excited about, and have delivered on the expectations and hopes of the multitude of shooters that have migrated to an all Sony workflow.

Even if you’re not a Sony shooter, you have to admire their dedication to creating some of the best featured bodies out there.

Sony’s Official Camera channel on YouTube has released a video (see below) showcasing the 4k that can be captured with the a7R II. While there are some small shooting errors on the video, it certainly shows the incredible and fine detail that the camera is capable of capturing.

The Phoblographer also has a very quick and dirty video demonstrating the AF ability of the a7R II.


The A7r II will be available in August of 2015 for $3,200.

Beautiful traditional landscapes of Shirakawa-go which is one of a world heritage site in Japan. α7R II's high resolution 4K movie recording function can record its beautiful scenery throughly. In Super 35 format, the α7R II collet 1.8x as many pixels as required for 4K movies. The data is then condensed to produce 4K movies, realizing images that exhibit higher resolution than typical 4K movies.
The ultimate high-resolution 4K movie experience.

Sony has just unleashed its new a7R II mirrorless camera, a followup to the highly-regarded a7R. The new camera features the world’s first back-illuminated full frame CMOS sensor, which shoots 42.4 megapixel photos at up to ISO 102400.

Sony is the worldwide leader in digital imaging sensors right now — it was behind 40% of all sensors sold in 2014 — and the Japanese company has packed the best of what it offers inside this new flagship full-frame mirrorless body.

In addition to high-resolution and fantastic low-light sensitivity, the camera has a 40% faster autofocus response time compared to the a7R, thanks to the help of 399 phase detection AF points and 25 contrast points. Sony says the backside illumination allows the camera to have both high resolution and high speed/sensitivity, instead of having to choose one or the other.

The design also improves data processing speed. Sony says files are sent out from the sensor 3.5x faster than in the original a7R.
