Interview with the developers.
VENICE is a very different kind of camera for Sony: everything from its name through to an all-new compact chassis and that uniquely cinematic look.
Sony has been part of digital cinematography from its modern day beginning, collaborating with George Lucas on his digital vision for Star Wars prequels. Early test shoots adapted existing Sony cameras such as the HDC-950P, but dedicated cameras such as the Academy Award winning F900 soon followed as well as the CineAlta brand itself. Each new camera generation has advanced imaging performance and features, but what’s remarkable is how the look of the cameras has evolved to be smaller and simpler – closer to traditional film cameras. VENICE represents the zenith of this evolution of technology and design.
For this interview we spoke to: Product Planner Yutaka Okahashi, Project Leader Yuji Ooba, Designer Shinsaku Hirano, Koji Izumi Mechanical Engineering.
Okahashi: Initial development began in early 2015 and was formally initiated a few months later. Full scale development started in April 2016.
Okahashi: VENICE is totally different from earlier CineAlta models, so looking back on the project I have to say there wasn’t anything that wasn’t demanding! Probably the most challenging element was the camera’s mechanical design as it was totally different from Sony’s normal design philosophy.
Some products have a very clear outline right from the start. VENICE was different: everything from the shape of the chassis to the interior layout to the performance specifications changed during development. It seemed that the further we got into the project, the more we learnt what VENICE could be and the engineers never gave up trying to achieve this vision. Whenever we felt we could deliver more by updating the original design, that’s what we did.
Okahashi: The magic of this camera has been called colour science, but it’s more than science, more than simply numbers, it’s a filmic look that evokes an emotional response from the viewer. So it seemed right to move away from product numbers and have a real name for this camera.
VENICE was taken from Venice Beach in Los Angeles. Venice, Italy is also a city well known for films. So when we began thinking about using a proper name, many alternate names were considered, but this was the one that worked best.
Ooba: There were many, many factors we considered in choosing VENICE’s sensor design – we didn’t want to simply iterate on what we had before, we went back to basics and conducted many conversations with customers.
We came to see a product concept that would offer exceptional imaging performance for a broad range of cinematography applications, not just one or two.
VENICE’s Full-Frame sensor can support virtually any aspect ratio permutation within Full-Frame and Super 35: widescreen spherical, widescreen anamorphic, 2.39:1, 1.85:1, 17:9. This means you can shoot with any cine or stills lens ever created. That’s special.
Of course, Sony’s α still cameras also use 6K Full-Frame sensors, so it might seem there’s some similarity in design. In fact, VENICE’s sensor is an all-new design 36x24mm developed exclusively for filming cinema films.
Izumi: Once VENICE settled on a Full-Frame sensor, we knew we needed to support the widest possible choice of lenses. There were a number of options, but from customers we got a very clear understanding of the need for simplicity and robustness above all.
To switch to E-mount, all you need is a screwdriver to remove the 6 screws which secure it and reveal the E-mount. That’s it. Very simple and straightforward for anyone to perform on-set. The E-mount itself uses the FS7 II design with a lever lock to provide robustness and security.
Ooba: People ask why we didn’t use the electronic variable ND filter from FS5 and FS7 II. We considered this option, of course, but from discussion with customers we knew that when filming cinema films, ND adjustments are made in steps, so this meant we had to develop something new for VENICE.
Izumi: 2 filters were necessary to create a glass filter from 0.3 (1/2) to 2.4 (1/256) and we had a hard time figuring out how to fit it in an 18 mm flange back. By consulting across Sony, we found a variety of advanced miniaturization technologies we were able to make it fit.
Izumi: We considered every detail! For example, most cameras are designed with the intake and exhaust ports on the top and bottom of the camera, but if it rains while filming, water enters the camera through them. For VENICE, the intake vent is located on the left and the exhaust vent is on the right. By separating the ventilation flow path from the electronic components, the camera’s operation is not affected even if water enters the intake and exhaust ports. That was our theory, but we also conducted tests with VENICE in harsh conditions and found that there were no problems with its operation even under extreme circumstances.
We also designed VENICE with on-set maintenance in mind. We knew that when shooting in harsh conditions, it’s easy for the fans to get dirty so on VENICE they can be changed very easily. Once the sensor module is removed, the fan can be extracted as simply as opening a drawer. As long as the customer is willing to accept the appropriate responsibility, the entire task can be done in a matter of minutes.
Hirano: We also decided to reflect this interior robustness with VENICE’s external design: adopting a new utilitarian grey colour with a distinctly bumpy texture on the magnesium chassis. We wanted VENICE to look and even feel in way that made its robustness quite obvious. It’s a small camera, but it’s tough enough for almost any mainstream cinematography application.
From discussion with customers we knew that when filming cinema films, ND adjustments are made in steps, so this meant we had to develop something new for VENICE.
Okahashi: Time is a lot of money on a film set. Superb imaging performance is of limited value if set-up time is too long, so this was a big focus for the team. We listened to customers on how they preferred to work and the number of buttons, layout and menu composition. We reduced the number of external buttons to 14 to achieve a more intuitive approach to operating the camera. A lot of time was spent tuning the controls to meet an operator’s needs, all the necessary functions in just the right places, paring away anything unnecessary that might interfere in an instinctive user experience.
The same user-focused approach was applied to the menu control interface. During normal use, there’s a simple interface providing quick access to all the key features, but it’s still possible to access a layer of more detailed controls to make more sophisticated adjustments. In fact, the VENICE team called on a UI expert from outside the professional group to provide a fresh approach. He spent a great deal of time with customers, analysing their usability requirements with paper outlines, often in private sessions at cinematography events. It’s one more reason to visit the Sony booth – being consulted on our next generation cameras!
Ooba: This camera is often used with camera assistants, so we took care to meet their needs with the main display on the side to increase the operability for them.
Izumi: One example of how VENICE’s design evolution offered new functionality is that when a space became available on top of the camera we immediately started thinking about how to use it. After much consideration, we decided to attach a slide rail to the top of the body. Doing so allowed independent movement of the handle and viewfinder stay. The viewfinder can also be rotated 90°, making it useful in locations where it is hard to see through the viewfinder like when you’re against a wall or in a car. We also considered the position of the terminal so the cables do not get in the way of the bottom space, allowing trouble-free panel operation and a sense of compactness when operating the camera even if many cables are inserted.
We changed the characteristics of the optical low pass filter and colour expression to achieve this cinematic look as default.
Ooba: The optical system on previous CineAlta cameras delivered very crisp and sharp imaging. It’s a popular approach and many users prefer it, but there are also people who prefer images with a soft tone and believe this is more cinematic. While earlier cameras such as the F55 can be configured to deliver this type of cinematic imaging, with VENICE we changed the characteristics of the optical low pass filter and colour expression to achieve this cinematic look as a default. This was one of the main goals in terms of image generation this time around.
Ooba: VENICE’s Full-Frame sensor can cut out S35 size imagery and its size and resolution is nearly same as F55, but the electronic storage capacity is several times larger than them. In fact, we’ve got more natural noise, and better latitude.
Ooba: We adjusted sensor colour to provide superior colour reproduction compared to F65/F55. Depth of colour is affected by noise, so better noise contributes better colour science. One key learning was how cinematographers use lighting on set – exceptional sensitivity is a great feature on a stills camera, but much less important on VENICE. In fact, picking up stray light from a smartphone can cause a significant problem. Knowing this, we tuned the sensor accordingly.
For monitoring, we provide a look, s709, that emulated film colour in addition to our existing realistic colour reproduction.
Okahashi: At the time of launch we set out a firmware roadmap with a clear schedule. We also paid close to attention to customer feedback since launch to bring forward features wherever possible. We knew from F55 – currently on version 9 firmware – that adding features is crucial. VENICE is designed to support this.
Additionally we just announced High Frame Rate support in the future. Using VENICE platform, we would like to add strong features step by step.
