Interview: Sony’s Masaaki Oshima – “The Alpha 1 is the first step towards the next decade”
Masaaki Oshima, Deputy Senior General Manager, Camera System Business Division, at Sony Imaging Products & Solutions. Pictured holding the new Sony Alpha 1.

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.

Accessory Roundup: the Nikon museum, a digital picture frame, and more


Images: pexar, SmallRig, Nikon

Welcome to this week’s accessory roundup. If we’re being honest, it’s been a bit of a dry one out there for accessory news; manufacturers have likely been busy getting ready for the upcoming Amazon Prime Day event that starts on October 8th, and the busy sales season that’ll follow the month after. However, we’ve dug deep and found some accessory news for you. Before we get to that though, let’s go back to talking deals for list a moment…

OM Cameras on sale

The OM-5, OM System’s compact Micro Four Third camera, is currently on sale for $1,000, $200 off its MSRP. When we reviewed it, we appreciated its capable stabilization, size, and weather sealing. While it certainly has some drawbacks like using microUSB instead of USB-C and the company’s older menu system, the less expensive price takes the sting out of those a bit.

The company’s high-end camera, the OM-1 II, is also $400 off, bringing its price to right under $2,000, body-only.

Taking a slight – okay, massive – step up in size, weight, and price, the Nikon Z8 is also $400 off. It’s one of the most powerful full-frame cameras we’ve reviewed to date, and won our Gold award last year.

It’s easy to understand where the name comes from, but Lexar better hope that a certain animation studio isn’t feeling particularly litigious.

Lexar, a brand probably best known for its memory cards and readers, has launched a new sub-brand to sell digital photo frames called ‘pexar.’ The announcement was made at IFA last month, but it flew under the radar for a bit until sites like Digital Camera World and PetaPixel picked up on it.

The first pexar-branded product is a 28 cm (11″) digital picture frame with a 2000 x 1200 touchscreen display that can go up to 400 nits of brightness, 32GB of built-in storage, a magnetic stand that lets you use it in portrait and landscape, and an anti-glare display. It also has an SD card slot and a USB-A port to let you expand how many pictures it can hold, but the company says you should be able to fit “over 40,000” images on it before you need to do that.

There’s also an app that lets “up to 512 users” connect to the frame and upload images or videos to it. This could be useful for those giving it as a gift to a family member or friend and who want to keep it updated with recent photos, or someone who wants to use it as a way to display their own photography without having to do prints.

At $160, it’s certainly positioned as a premium product, though it’s also not the most expensive option in the category. It also has a higher resolution than The Wirecutter‘s pick for a 38cm (15″) digital photo frame. The company also says that a smaller 25.7cm (10.1″) version is in the works and will launch sometime this month.

Lights, camera, action

Chip-on-board lights, or COB lights, have become popular tools for both photographers and videographers looking for a continuous light source. Recently, both SmallRig and Lume Cube announced portable COB lights, which could be handy if you find yourself needing a fill light. Both lights can be remotely operated with an app.

As its name implies, the SmallRig RC 100B is a 100W-class light. It uses bi-color LEDs, so you can have it output light at 2700-6500K. There are two different RC 100B kits; the first is the “mobile” version which mounts to a handle and includes an adapter plate that lets you use two NP-F batteries instead of the V-mount ones the light natively takes. The standard version, meanwhile, includes a light stand adapter and USB-C cable for power. Both versions also have a mini XLR input for DC power.

The mobile version retails for $199, and the standard one is $229.

The Lume Cube XL puts out less light – it’s only a 60W-class source – but adds RGB capabilities that let you output in different colors. Like the SmallRig light, it includes a reflector, and can accept power input via USB-C. It doesn’t include a built-in battery mount, though you can buy a battery handle separately, but does come with a power adapter that lets you plug it into the wall.

The Lume Cube XL is available for $249.

This one is less of an accessory and more of a place you can go to see a ton of camera gear. Nikon has announced that it’ll reopen its museum on October 12, after closing it while relocating its headquarters. There, you’ll be able to see around “1,300 products and technologies” from Nikon’s camera, lens, binocular, and industrial businesses. Perhaps most excitingly, the consumer section has a “touch and try” section, though the company’s map doesn’t have much detail on what types of products you’ll be able to get your hands on.

Admission to the museum is free, but you’ll obviously have to physically be in Tokyo if you want to visit.

If you do want to buy something, the museum has a gift shop that sells “15 types of acrylic keychain” that depict cameras and lenses, which are quite adorable and only 500 yen (around $3.40 US at time of writing).

How one photographer turned a DIY dream into a full-frame reality

How one photographer turned a DIY dream into a full-frame reality


The Sitina S1

Photo: Wenting Zhang

Here at DPReview, we love DIY photography projects, and one recently came to our attention that we just had to share.

Boston-based engineer and photographer Wenting Zhang has been experimenting with DIY electronics for over a decade and also loves taking photos, so building his own camera was a natural extension of these interests.

“I initially had the idea of building my own camera during middle school. Back then, I wasn’t allowed to use my parents’ camera and couldn’t afford a real camera. I naively thought it would be possible, and cheaper, if I just built one myself,” Zhang told DPReview. His initial attempt didn’t go well, and he eventually saved enough to buy a used Nikon D90, but the itch to build his own camera stayed. Whenever he saw someone posting about a DIY camera project, he thought, “If other people can pull that off, I should be able to as well.”

In this recently published video, Wenting Zhang walks through assembly of his current prototype camera.

Zhang says he started the project in 2017, and it’s not finished yet. “Engineers are usually bad at estimating how long things will take. I am probably particularly bad at that. I expected this project to be challenging, so it would take a bit longer, like probably one year. Turned out my estimation was off,” he says.

He makes clear to point out that this is a hobby project, purely for fun, and that his camera isn’t going to achieve the level of image quality found in commercially available products from established companies. Despite that, his project provides a fascinating look into what’s involved in building a camera from the ground up. What’s more, Zhang has open-sourced his entire project on GitLab for anyone else who might want to build upon it.

Zhang took this photo with a monochrome version of the Sitina, which uses the same sensor but without the Bayer color filter array.

Although CMOS has become the dominant sensor technology in consumer cameras, owing to factors like speed, lower power consumption and cost, Zhang’s camera is built around a 10MP Kodak KAI-11000CM CCD sensor with a global electronic shutter, which he selected for a rather pragmatic reason: it was easy to source. “Most manufacturers (like Sony) aren’t going to just sell a sensor to a random hobbyist, so I have to buy whatever is available on eBay. This 10MP CCD turned out to be available,” he explains.

Zhang attaches the CCD sensor to his heat sink.

The choice of sensor has a useful benefit. As he explains in one of his videos, designing and building a mechanical shutter is complicated and beyond his area of expertise, so his DIY design is based on using an electronic shutter. For similar reasons, he chose to use an LCD screen as a viewfinder rather than a prism-based optical design, resulting in a mirrorless camera.

Zhang wanted his design to be compatible with existing lenses. His mirrorless design, with a short flange distance, provided a great deal of flexibility to adapt different lenses to the camera, and he’s currently using E-mount with active electrical contacts.

And that’s just the start. Zhang also needed to integrate a CCD signal processor with an ADC (analog to digital converter), a CPU, battery, an LCD screen and buttons. He also designed and built his own circuit board with a power-only USB port, flash sync terminal, power button and SD card slot, and create the software and user interface to tie it all together.

In order to build his camera, Zhang had to design and print his own circuit boards.

Finally, everything fits inside a 3D-printed enclosure that, to my eye, looks rather attractive.

As for the camera’s name, the Sitina S1? “I simply put the word ‘silicon’ and ‘retina’ together to form the word ‘sitina’. I don’t have any better ideas of naming the camera model, so I simply call it the ‘Sitina S1’, he explains. “But the name may change in the future if I ever have better ideas.”

Zhang was kind enough to share some photos from his DIY ‘for fun’ camera.

Now that he’s built his own camera, Zhang has an appreciation for how much work goes into the design, development and optimization of a modern consumer camera. “I would imagine it would take an army of designers and engineers of various disciplines to build a modern consumer camera,” he says. “There are so many different components but few ‘off the shelf’ parts.”

“On top of the hardware, we still have layers of software. There’s no standard camera operating system (like Android or Windows) so each vendor is developing its own OS. On top of the OS, you have image processing algorithms where each vendor probably has their own secret sauce for better color, lower noise, etc. I think it’s quite incredible that camera vendors are able to do all these things in-house.”

In this video, Wenting Zhang dives into the technical details of what’s required to design a working camera.

Zhang is still working to address issues in his current prototype. “I think in another year or two it could reach a state where it can be a useable and useful camera. I do wish to sell the camera either as a kit people can put together or as an assembled machine. Not for profit, but so people can play with it, and my effort on this project won’t go to waste.”

If you’re curious to learn more about how a camera is built, I encourage you to watch both of Zhang’s videos in their entirety as he goes into great detail about the process. And, if you have the technical skills and interest to try this type of DIY project yourself, his open source project could be invaluable. I’ll be the first to admit it goes beyond my level of engineering know-how, but I would be first in line to order a Sitina camera DIY kit if the opportunity arose.
