Sony shook up the camera industry recently with the launch of three new cameras - the Alpha a7R II, Cyber-shot RX100 IV and RX10 II. We were in New York for the launch event, and after the dust had settled we sat down with Kimio Maki, Senior General Manager of Sony's Digital Imaging Business Group. In our interview, we spoke with Mr. Maki about the process of designing the new Alpha a7R II, and what he has learned from customers invested in the a7-series. 
Also present was Mark Weir, Senior Manager of Technology at Sony Electronics USA, indicated by 'MW' in the following interview.

KM: A lot. We got a lot of feedback from our customers, around things like durability and shutter shock - too much to explain here. And even from the a7II, when we introduced that product we received a lot of requests and requirements for improvements and we’ve incorporated those things as much as possible [in the a7R II]. For example the recording button should be customizable, and you should be able to switch in-camera from PAL to NTSC etc. Those kind of things.

When we first started to develop this full-frame back-illuminated sensor, the most important thing was that it had to have high resolution - no less than 36MP. Also we wanted 4K video using the entire area of the sensor, as well as a Super 35 crop. Then we calculated that the best pixel count to accomplish these goals was 42MP.

What is the biggest technical challenge to making a camera like this?
a7R II¸¦ °³¹ßÇϴµ¥ °¡Àå Å« ±â¼úÀû ¾î·Á¿òÀº ¹«¾úÀ̾ú½À´Ï±î?
KM: To create a balance between resolution and ISO sensitivity. Usually, if you increase resolution, you have to sacrifice sensitivity. To achieve both we created a full-frame back-side illuminated sensor. We needed resolution of 40MP+ and we also needed ISO sensitivity greater than 6400, and in order to achieve that balance, this [BSI CMOS] technology is necessary. Once you’ve gathered the light, improving processing speed is an important issue, so we changed the wiring inside the sensor from aluminum to copper, and reversed the structure. So we’ve improved the resolution and the ISO sensitivity over the original a7R.

MW: We wanted to overcome the idea that has been prevalent since as long as there have been digital cameras, that you can have one virtue [resolution] or the other [sensitivity] but you can never have both. Look at the Canon EOS 5DS. A maximum ISO sensitivity of 6400, and crippled movie capability. Canon says that it intentionally created the camera to fit the requirements of certain photographers, and [has thereby demonstrated] that the material science of their device technology [cannot] accomplish both objectives.

"VIDEO"


MW: The a7S has exactly the right number of pixels to use the full width of the sensor to shoot 4K, with no line skipping or pixel binning. The a7R II can’t do that. […] However, when set to the Super 35 crop, the a7R II sensor has a read speed fast enough to read every pixel and super-sample those pixels into an 8.3MP [4K] frame, without dropping any lines and without any pixel binning at all. So in theory, in that mode, video from the a7R II should be superior to almost any other 4K capture device.

In terms of autofocus, [the gap between DSLR and mirrorless] is getting smaller and smaller. In terms of noise reduction we’re learning a lot from our competitors about the best way to do it.

The a7S is Sony's flagship a7-series camera for video. Featuring 'first-generation' a7 ergonomics but a unique 12MP full-frame sensor, the a7S can record 4K video using the entire frame with no line skipping. The a7R II can do this too, but in a cropped Super 35 mode.

KM: The trend is moving. It used to be that stills were stills and movies were movies, and the [customers] were completely different. But about three years ago, video customers started to use the Canon EOS 5D Mark III for both still images and video capture. That kind of product started to change the industry. The customers' demand is evolving.

KM: Yes, but that advantage is getting smaller and smaller. I don’t know when we will [surpass] that technology but we will do our best. When we introduced the a6000, a lot of professional customers started to buy it. We asked them why, and they told us ‘this is my holiday camera’. They told us that for their jobs, they used [DSLRs] but when they go out with their families they used the a6000, because the quality level is very close.

When the a6000 was launched, the benefit of its ‘4D’ focus system was a big part of the marketing strategy. Is the system in the a7R II equivalent in terms of ability?

KM: It’s almost equivalent but the [imaging circle] is larger. The gap is getting smaller, but in terms of speed, APS-C is still quicker because the lens elements are smaller and lighter.

The big advantage of a phase-detection system on the sensor is that micro-adjustment is not necessary. In the case of Canon and Nikon, with sensors of greater than 15MP, you have to adjust the cameras and lenses very precisely.

KM: I hope that our native lenses are better! But it will happen. I see people using Sony a7-series bodies and third-party lenses all the time, for video and for stills, because they already own the lenses. It works, but our native lenses are much better and that’s the process [we see a7-series buyers going through]. Of course we’re not putting them under any pressure, but in order to make them shift, we have to guarantee the quality of the lens. Our lenses have to be better than [those from other manufacturers]. That is my mission.

The a7R II's 399-point PDAF system looks very nice indeed, and can even drive AF with Canon EF lenses mounted to the camera via a third-part adapter. Although Sony is not selling this as a 'feature' (the company would love it if people bought its native FE-mount lenses instead) this level of compatibility with Canon optics might smooth the upgrade path for anyone thinking of changing systems.
