Following the launch of Sony’s new Alpha 1 (a1) full-frame mirrorless interchangeable lens camera, we sat down (virtually) with Masaaki Oshima, Deputy Senior Manager of Sony’s Camera division. As well as discussing how the Alpha 1 came into being, we also discussed the changing camera market, and how Sony intends to meet the needs of a new generation of photographers.

This interview has been edited lightly for clarity and flow.


How long has the Alpha 1 been in development?

It’s very hard to answer that – I can’t give you the exact duration of time, but it did take longer than previous models. It was very hard to develop.

The main reason is that it has a totally new imaging sensor. This new sensor has incredible specifications, and integrating it into a camera body in a way that maximizes the power of the sensor was very difficult to achieve. That took a long time.

From the very beginning we’ve been developing this camera for professionals. We aimed to exceed the expectations of both stills and movie shooters. The Alpha 1 is developed with no compromise for top professionals, I think.

What is your wider strategy for growing your professional user-base?

We’re always listening to feedback from professional customers, and reflecting it in our development. The relationships we have with professionals now are very good, and we will continue [to develop] these relationships and create products and services based on their feedback. Professionals provide us with new insights into what they want and how we can improve, they also give us hints on things we have never thought about. I think that once professionals use the Alpha 1 they will love it.

Sony’s new Alpha 1 is a powerful, versatile mirrorless interchangeable lens camera with a cutting-edge BSI-CMOS sensor. We’ve exposed the sensor here, but normally, with the lens removed, it is protected by the blades of the newly developed mechanical shutter.

Was 8K video part of the plan from the beginning?

Yes, we think that [the division between] stills and movies is less and less, nowadays. So we aimed to achieve both high quality video and high resolution photos in the same body.

Right now 8K isn’t widely popular, but we’re sure that demand will evolve, and 8K implementation is important in order for us to be successful in the future. And even now, some professionals will be interested in capturing 8K and cropping to 4K, for example. I think that the Alpha 1 is the first step towards the next decade. That’s one of the reasons why we named it ‘Alpha 1’, meaning ‘first step’.

We’ve been talking for a long time about the eventual development of global shutter technology in consumer digital imaging. Is that a technology that Sony is still interested in pursuing?

Sony already launched a global shutter sensor. It’s a small sensor, which is used in security cameras, machine vision and professional camcorders etc. We understand the advantages of global shutter, such as simultaneous data readout, but for commercial use in a full-frame format, there are some challenges around design and engineering, and also production issues. So right now, the new sensor in the Alpha 1 is the most practical.

The sensor in the Alpha 1 is so fast, why did you decide to include a mechanical shutter at all?

Well, thank you for saying so! But it’s not fast enough. Top photographers require a faster flash sync speed, of more than 1/300 sec. So we implemented a mechanical shutter with a totally new structure – a dual drive shutter system utilizing spring and electromagnetic drive actuators.

Are there any other technologies in the Alpha 1 which are completely new, and developed just for this camera?

The sensor and the shutter are both totally new [and unique to the Alpha 1]. The imaging processor and EVF are the same as the Alpha 7S III, but [we] built these into the Alpha 1 with the best tuning to maximize its performance.

The Alpha 1 and a7S III are the first in a new generation of Sony cameras which feature improved ergonomics, a redesigned body construction, and a new, highly detailed electronic viewfinder.

Can you tell us more about the construction of the Alpha 1? How is it different?

We’re still using a magnesium alloy body, but the way the parts are combined makes it more rigid. I’m sure you’d like to know about the sealing, and that’s totally different to the previous models. Compared to previous cameras, the a7S III and A1 have a totally new body structure. I can’t give you details, but we’re using very advanced [sealing] technology with the Alpha 7S III and the Alpha 1.

Is the Alpha 1 your best constructed, and best-sealed camera?

Yes. And of course the mechanical shutter now closes when you change lenses, which will provide more durability for professional use. Another reason for a mechanical shutter!

Traditionally, it’s been understood that you can either have high speed, or you can have high resolution. It’s difficult to provide both. How did you achieve this combination in the Alpha 1?

We had to develop a new sensor, and we implemented our latest imaging processor as well as a totally new analog to digital conversion method. That’s how we achieved high resolution and high speed. I cannot give you any additional details, I’m sorry!

The Alpha 1’s imaging pipeline would appear fast enough to support some of the computational photography features that are becoming more common in smartphones and certain other imaging devices. Are you planning on introducing such features into the Alpha 1 and future cameras?

I watched your DPRTV episode recently about computational photography, and I know you’re interested in it. We haven’t implemented any so-called ‘computational’ photography features in the Alpha 1, but we do have features like Pixel Shift Multi Shooting, and long-exposure noise reduction, and they’re based on the same kind of idea.

In our Cyber-shot range we’ve introduced features for enhanced dynamic range and things like that. I can’t talk about plans for specific features in specific models but fast sensor readout is advantageous [for such features].

Do you have requests from customers for computational photography features? Things like Pro Capture in Olympus Micro Four Thirds cameras.

At the moment, no. We’ve not had those kinds of requests from top photographers. But we may consider it, if we get that feedback. I’m not sure.

What’s next for Sony in autofocus development?

We’ve evolved our autofocus functions, but we still think there’s room to improve. We will continue to strengthen our current technologies, but also will also [continue to develop] object and scene recognition – that will be key.

What do you see as the biggest unaddressed customer need in the consumer DI marketplace right now?

The demand for video, and [the needs of] young creators has not yet been addressed. The COVID-19 situation changed all of our circumstances, and also customers requirements changed, to everything being online. The creativity of young creators, and their desire to improve the quality of their pictures never stopped. So their demands are accelerating! And we have not yet addressed this yet. That’s why for example we’ve introduced concepts like the ZV-1.

Sony’s upcoming Airpeak Drone, which will be powerful enough to carry an Alpha-series full-frame mirrorless interchangeable lens camera.

What is your strategy for bringing these young creators into the Sony ecosystem?

They want to shoot high quality pictures and video, but they might not know how to use conventional cameras. The key is to integrate our high technology in a simple, easy-to-use way. So the high-end technology that we developed for the Alpha 1 will be developed further and modified, simplified [and implemented in] ZV-1-type products.

How do you think content creation will be different in the future compared to now?

I think you want me to talk about computational photography again! But before that, as I said earlier, the boundary between stills and video will continue to be less and less [distinct]. So ‘hybrid’ shooters who create stills and movies will need to be satisfied. So we will [make devices] for them. And not only cameras, but the total workflow, from preparation onwards. This workflow is very important. So connecting, transmitting, and editing. That’s key for us.

We recently launched the new professional 5G device, Xperia PRO, and we’ve also announced our Airpeak drone. We will broaden our imaging world not only with cameras but also with smartphones and drones [all working together].

What do you see as the biggest challenge facing Sony’s camera division in 2021?

Since we entered this industry and developed our first mirrorless cameras ten years ago, we have been in a leading position. So we’ll continue to focus on developing our mirrorless cameras and make the market bigger. That’s our biggest challenge, to maintain this position. We will launch other cameras this year, not just the Alpha 1. We’ll never stop innovating and developing, not only cameras but also lenses. We aim to be the leader of this industry, by continuing to offer the best customer experiences.


Editor’s note: Barnaby Britton

This interview was the first time I’ve spoken to Mr Oshima, and his pride and excitement following the launch of the new Alpha 1 was clear in our conversation. Sony has made significant inroads in recent years with professional photographers, getting its cameras and lenses into the hands of an increasing number of photojournalists and sports photographers, a process aided by the signing of deals with major organizations and agencies. These days, Sony’s mirrorless cameras can be found everywhere from sports stadiums to the White House, which is something that would have seemed like a pipe dream back when the original A7 and A7R were released almost a decade ago into a market dominated by Canon and Nikon DSLRs.

Sony hasn’t always had the best reputation for ruggedness, but according to Mr Oshima, durability was a major priority in the design of the Alpha 1

According to Mr Oshima, the Alpha 1 is the most ‘pro’ of Sony’s professional ILCs to date, and accordingly, it took longer to develop and more difficult to bring to market than previous models. It’s certainly a highly complex camera, which – along with the recently announced a7S III – represents something of a new direction for Sony in terms of ergonomics and build. Sony hasn’t always had the best reputation for ruggedness, but according to Mr Oshima, durability was a major priority in the design of the Alpha 1 (which helps to explain why despite its super-fast sensor it still has a mechanical shutter: to protect the sensor).

Sony sees the Xperia PRO smartphone as being a companion device to its high-end cameras for video professionals.

Only time will tell whether the Alpha 1 ends up being regarded in the long run by photographers as ‘the first step towards the next decade’ but the depth of its feature-set (including 8K video) is certainly among the most future-proof of any full-frame camera that we’ve seen, including high-tech competitors like Canon’s EOS R5.

Curiously though, despite its high-speed sensor and formidable processing power, the Alpha 1 doesn’t offer much in the way of computational photography tricks. This is a shame, because assuming professionals could get used to a slightly new way of working, a feature like Olympus’s ‘Pro Capture’ in the a9 II and / or Alpha 1 would be quite something. We’re still waiting for Sony to get more confident about redefining traditional ideas of exposure, too, to help photographers make the most out of the company’s current-generation dual-gain BSI-CMOS sensors. Hopefully one day.

More new cameras and lenses are promised in 2021, and a continued commitment to innovation across Sony’s product lineup

So what comes next? Mr Oshima hints at an increasingly blurry boundary between stills and video imaging, and continued development of object and scene recognition. If that’s starting to sound like computational photography, well, we’ll see. Either way, he also promises more new cameras and lenses coming in 2021, and a continued commitment to innovation across Sony’s product lineup. As Sony builds out its high-end smartphones (and kudos to the company for finding a niche for that technology with the creator community) and drones, we’d also expect to see more of a focus on end-to-end workflow, and hardware integration across the company’s wider product portfolio.

Pentax K-1 and K-1 II firmware updates include astrophotography features (depending on where you live)


When you use DPReview links to buy products, the site may earn a commission.

Yesterday, Ricoh quietly released firmware 2.50 for its Pentax K-1 and K-1 II DSLRs. However, the features you can expect to gain from this update may depend on your geography.

Ricoh’s English-language firmware pages for the K-1 and K-1 II state that firmware 2.50 delivers “Improved stability for general performance.”

However, astute Pentax users noted that Ricoh’s Japanese-language firmware pages (translation) indicate that the update also includes a limited feature called “Astronomical Photo Assist,” a collection of three new features designed for astrophotography: Star AF, remote control focus fine adjustment, and astronomical image processing.

Star AF is intended to automate focusing on stars when using autofocus lenses. Rather than manually focusing on a bright star and changing your composition, it promises to let you compose your shot and let the camera focus.

Remote control fine adjustment allows users to adjust focus without touching the lens and requires Pentax’s optional O-RC1 remote. Astronomical image processing will enable users to make in-camera adjustments to astrophotography images, including shading correction, fogging correction, background darkness, star brightness, celestial clarity, and fringe correction.

Astronomical image processing on the K-1 and K-1 II will enable users to make in-camera adjustments to astrophotography images, including shading correction, fogging correction, background darkness, star brightness, celestial clarity, and fringe correction.

According to Ricoh, Astronomical Photo Assist is a premium feature that must be purchased and costs ¥11,000 for an activation key (about $70 at current exchange rates).

Although these astrophotography features appear to be Japan-only for now, a Ricoh representative tells us, “Ricoh Imaging Americas confirmed that the premium firmware features for the PENTAX K-1 and PENTAX K-1 Mark II will eventually be available to US customers.”

Firmware update 2.50 for both the K-1 and K-1 II is available for download from Ricoh’s website.

On this day 2017: Nikon launches D850


When you use DPReview links to buy products, the site may earn a commission.

As part of our twenty fifth anniversary, we’re looking back at some of the most significant cameras launched and reviewed during that period. Today’s pick was launched seven years ago today* and yet we’re only quite recently stepping out of its shadow.

The Nikon D850 is likely to be remembered as the high watermark of DSLR technology. We may yet still see impressive developments from Ricoh in the future (we’d love to see a significantly upgraded Pentax K-1 III), but the D850 was perhaps the green flash as the sun set on the DSLR as the dominant technology in the market.

Why do we think it was such a big deal? Because it got just about everything right. Its 45MP sensor brought dual conversion gain to high pixel count sensors, meaning excellent dynamic range at base ISO and lower noise at high ISOs. Its autofocus system was one of the best we’ve ever seen on a DSLR: easy to use and highly dependable, with a good level of coverage. And then there was a body and user interface honed by years of iterative refinement, that made it easy to get the most out of the camera.

None of this is meant as a slight towards the other late-period DSLRs but the likes of Canon’s EOS 5DS and 5DSR didn’t present quite such a complete package of AF tracking, daylight DR and low-light quality as the Nikon did. With its ability to shoot at up to 9fps (if you used the optional battery grip), the D850 started to chip away at the idea that high megapixel cameras were specialized landscape and studio tools that would struggle with movement or less-than-perfect lighting. And that’s without even considering its 4K video capabilities.

In the seven years since the D850 was launched, mirrorless cameras have eclipsed most areas in which DSLRs once held the advantage. For example, the Z8 can shoot faster, autofocus more with more accuracy and precision, across a wider area of the frame and do so while shooting at much faster rates.

But, even though it outshines the D850 in most regards, the Z8 is still based around what we believe is a (significant) evolution of the same sensor, and its reputation still looms large enough for Nikon to explicitly market the Z8 as its “true successor.”

Nikon Z6III added to studio scene, making image quality clear

We’ve just received a production Nikon Z6III and took it into our studio immediately to get a sense for how the sensor really performs.

Dynamic range tests have already been conducted, but these only give a limited insight into the image quality as a whole. As expected, our Exposure Latitude test – which mimics the effect of reducing exposure to capture a bright sunrise or sunset, then making use of the deep shadows – shows a difference if you use the very deepest shadows, just as the numerical DR tests imply.

Likewise, our ISO Invariance test shows there’s more of a benefit to be had from applying more amplification by raising the ISO setting to overcome the read noise, than there was in the Z6 II. This means there’s a bigger improvement when you move up to the higher gain step of the dual conversion gain sensor but, as with the Z6 II, little more to be gained beyond that.

These are pushing at the extreme of the sensor’s performance though. For most everyday photography, you don’t use the deepest shadows of the Raw files, so differences in read noise between sensors don’t play much of a role. In most of the tones of an image, sensor size plays a huge role, along with any (pretty rare) differences in light capturing efficiency.

Image Comparison

As expected, the standard exposures look identical to those of the Z6 II. There are similar (or better) levels of detail at low ISO, in both JPEG and Raw. At higher ISO, the Z6III still looks essentially the same as the Z6II. Its fractionally higher level of read noise finally comes back to have an impact at very, very high ISO settings.

Overall, then, there is a read noise price to be paid for the camera’s faster sensor, in a way that slightly blunts the ultimate flexibility of the Raw files at low ISO and that results in fractionally more noise at ultra-high ISOs. But we suspect most people will more than happily pay this small price in return for a big boost in performance.
