Last week, Fujifilm announced the GFX100RF, a fixed-lens camera with a 102MP medium format sensor. The company graciously flew us to Prague to cover the event live, and we got the chance to sit down and discuss the launch with three of the people who helped make it happen: Makoto Oishi, senior manager of GFX product planning, Yuji Igarashi, Manager of Fujifilm's Professional Imaging Group and TJ Yoneda, assistant manager of GFX product planning.
Our conversation mostly centered on the new camera and the design decisions that went into it, but we also talked a bit about the company's content authenticity efforts as well.
Who is the GFX100RF for?
According to Makoto Oishi, the GFX100RF is made for a different kind of photographer than most of the company's other medium-format cameras. "The GFX 100 II and the 100 S II are mainly for current GFX users who shoot landscapes, portraits or commercial. The GFX100RF is a little bit more for street photography or documentary, because we developed this one to be as small and lightweight as possible."
It's designed to be a luxury camera...

At first glance, the GFX100RF looks a lot like a larger X100VI, especially with respect to its controls and rangefinder styling. However, according to Oishi, the company didn't set out to design a camera with a family resemblance. "It's not that we didn't care, but we didn't design this camera with too much respect to the X100."
Part of the reasoning is that the GFX100RF is a much more expensive camera than the X100VI, which means it needs to feel more premium. "At the beginning, when we discussed how we should design the camera, we already knew about the price point. So this camera should be more luxurious to match the price point," said Oishi.
"Milled aluminum is the top end of manufacturing"
A major factor in its luxury design is the top plate, which is milled out of a single block of aluminum—it's the first time Fujifilm has used this type of manufacturing process. "Milled aluminum is the top end of manufacturing," said Oishi. Because you're milling from the block, you can have a lot of unique designs—more flexible designs," said Igarashi. Oishi agreed, saying, "With milling, we can develop any complicated, complex shape."

Later, during the Fujikina event, Yoneda told us that turning an aluminum ingot into a GFX100RF top plate takes around five hours. Even the side of the hot shoe mount is milled. "It has many special parts," said Oishi.
The company also redesigned the lens hood, creating an adapter ring that only goes one way, which the rectangular hood then attaches to normally. "With the X100VI, it just attaches by screwing on, which can be quite tough to align. This one has tabs affixed on the lens," so it aligns perfectly every time.
... while still being as compact as possible
"This is not an interchangeable lens, so we can be kind of flexible on the design of the sensor and the lenses," said Yoneda. "So the rear element of the lens is really close to the sensor, which is almost covering the sensor size. That's one of the reasons we can create such a small lens."
"We actually have considered several options for the focal length and aperture, and this was what we can make the most compact lens with the best image quality." It also lets you get away with hand-holding the camera at lower shutter speeds, which is important given the camera's lack of stabilization for the sensor or lens. Unsurprisingly, the exclusions were made to make the camera as small as possible – the company said that adding IBIS would've made the camera noticeably larger and heavier.

And if you want a closer field of view? "Since it has the 102-megapixel sensor, we can use the digital teleconverter for the telephoto side," said Yoneda.
As for whether the GFX100RF will ever get add-on optical lenses to change its field of view, similar to those for the X100 series, the company says it thinks the digital teleconverter is the way. "At this moment, we think that because of the 102MP, the digital teleconverter works," said Yoneda. "But depending on the users' feedback, we can, of course, consider any possibility of the wide-angle and teleconverter."
On the aspect ratio dial

One of the most prominent features of the GFX100RF is its large dial for controlling the aspect ratio of your JPEGs. While the company's GFX cameras have long let you emulate aspect ratios from some of its most famous medium format film cameras, this is the first one with a dedicated physical control for it. "I think this analog dial is kind of a connection between the digital technology and the film cameras we have," said Igarashi.
"We are trying to grab new customers with respect to our medium format cameras," said Yoneda. "So we thought this camera was the best one to install that kind of homage to those cameras."

It's also part of the company's philosophy of helping you produce pleasing images straight out of camera. "We wanted to offer to use this to change the aspect ratio not in post-processing, but when you're starting out with the subject," said Yoneda.
As for why it's a dial? "Actually, I wrote the nine types of format vertically," said Oishi. "And when we discussed how the user should choose between these formats... in a menu, it's quite tough. Even assigning it to a function dial or button or something like that... hmm. And then someone said, 'If we can implement it as a dial, is it easier?' And everybody said, 'Oh yeah, that's it!'"
Why there's no hybrid viewfinder on the GFX100RF

Several of Fujifilm's photo-focused cameras feature a hybrid viewfinder, which can act as both an optical viewfinder with an electronic overlay or as a purely electronic one. While it doesn't allow for true rangefinder focusing, it does provide a rangefinder-like experience... which is why we were initially confused that the company didn't include it on a camera whose name explicitly refers to a rangefinder design.
According to Yoneda, there are good reasons for it. "The hybrid viewfinder's structure is a little bit complicated, which means the magnification would be much smaller for such a high-resolution camera," he said. Those differences weren't just theoretical, either. "Of course, we created mockups with the hybrid viewfinder installed."
"Another reason is the digital teleconverter. If it comes with an OVF, we'd have to cover 20mm of range when using the teleconverter, which would make the guide-lines much smaller. So, from a practical point of view, we decided to install the EVF."
Will the GFX100RF get support for content credentials?
At its X Summit event announcing the camera, Fujifilm also mentioned that it had begun testing tools for dealing with content credentials, which can help authenticate a photo as being real versus AI-generated and can also provide a record of how a photo was edited. The company is part of the Content Authenticity Initiative and the Coalition for Content Provenance and Authenticity.
"We are still developing and investigating how to implement the CAI and the C2PA," said Oishi. "Unfortunately, we haven't decided on the final specification yet. But we believe this is a very important thing for photography."
"We have to, as an industry, come up with a standard"
As for whether the tech will come to existing cameras like the GFX100RF, Oishi says it depends on the details. "If we have to pay to implement it, or if users have to pay... not so many will want it. Then it'll only be for professional agencies or something," he said. "But if it is free, then we can manage the picture generation – what is real photography? And that is quite important."
"I think, of course, that will become more and more important, so we can't ignore it," said Igarashi. "So we have to, as an industry, come up with a standard. And be aligned, so we can at least define what AI is and photography is, and we can separate the images that we create."
To him, it's not necessarily about AI versus photography; it's about transparency. "We're not saying AI is not good or anything. It's just knowing what has been done through the process; I think that's important."
