Fujifilm GFX100RF review: A powerful and fun camera that's far from perfect
After watching its fixed-lens X100 VI camera do stratospheric sales numbers, Fujifilm decided to build a bigger and badder version that could go up against Leica's full-frame Q3. The result is the $4,899 GFX100RF, the first-ever 100-megapixel medium format compact camera.
The GFX100RF has some novel features, like a crop dial that lets you choose aspect ratios ranging from vertical 3:4 to a panoramic 65:24. It can digitally zoom via a dedicated toggle and offers all the social media-friendly benefits of the X100 VI, including film simulations. You can even shoot medium-format 4K video.
However, the GFX100RF has some flaws. Where Leica's Q3 has a fast 28mm f/1.7 lens and optical stabilization, Fujifilm's 35mm lens (28mm equivalent) here is limited to f4 and lacks any shake reduction, hurting the camera in low light. I've used the camera for nearly two weeks now and enjoyed it, but given the high price and quirks, it's definitely not for everyone.
The GFX100RF is the world's first 100MP medium format compact camera. It offers incredible image quality and flexibility but isn't great in low light, and the high price makes it a niche product. $4,899 at B&H Photo Video
Though it's Fujifilm's smallest medium-format camera, the GFX100RF is still a hefty unit at 735 grams. That's more than many full-frame mirrorless cameras and around the same weight as the Q3. The control layout is similar to the X100 VI with control dials on the front and back, along with exposure compensation, shutter speed and ISO controls on top.
What's new is the aspect ratio dial that offers modes for 4:3, 3:2, 16:9, 17:6, 3:4, 1:1, 7:6, 5:4 and 65:24 (the latter pays tribute to Fujifilm's TX-1 panoramic camera). The GFX100RF also has a toggle up front to select 28mm, 35mm, 50mm and 63mm (full-frame equivalent) zoom levels. Those gradually lose resolution due to cropping, from 100MP at 28mm down to 20MP at 63mm. Bokeh is also reduced as the sensor size shrinks.
The rear 2.1-million-dot, 3.15-inch display only tilts up and down, but that's fine for the camera's primary street photo role. Though sharp and detailed, the 5.76-million-dot electronic viewfinder unfortunately lacks the X100 VI's signature hybrid display that lets you switch between optical and electronic views. However, it does offer three modes to support the aspect ratio dial and make composition easier. One only shows the selected crop, another shows the full scene with a box around the crop and the third displays everything outside the crop at 50 percent opacity.

Battery life on the GFX100RF is outstanding with up to 820 shots on a charge or about 100 minutes of 4K 30 fps video shooting. For me, that amounted to nearly two days of use, which is better than nearly every other (non-DSLR) camera I've tested. The camera also includes dual UHS-II memory card slots plus mic, headphone, microHDMI and USB-C ports. The latter allows not only data transfers and charging, but also SSD video recording.
The GFX100RF is essentially a GFX100S II squeezed into a compact body, so performance is similar with up to 6 fps burst shooting speeds. However, each RAW file is up to 150MB in size and JPEGs are 70MB, so even at those slower speeds, you can fill your memory cards very quickly. That said, this camera definitely isn't designed for sports or wildlife, so I didn't use burst shooting often.
The autofocus is reliable when shooting single photos, but it's a little laggy for bursts. Using the face and eye detect AI modes helps nail eye focus reliably, but it's not as fast as Sony and Canon's systems. It also supports animal, bird and vehicle tracking, which helped me capture sharp photos of ducks floating on the Seine river in Paris.
The GFX100RF has both mechanical and silent electronic shutter modes. Rolling shutter skew is a big issue with this sensor in silent mode with fast moving subjects, though. Luckily, the mechanical shutter eliminates that and is nearly inaudible.
The built-in ND filter can reduce light up to four stops, letting you shoot on sunny days while retaining some bokeh. However, the main problem is when there's not enough light. The minimum f4 aperture is simply inadequate and the lack of stabilization exacerbates the issue as you risk blurry photos at slow shutter speeds. In dim light you may need to pack a tripod, which isn't ideal for a compact camera.
The aspect ratio and zoom options on the GFX100RF are handy and fun. Some curmudgeons may prefer to shoot full sensor 100MP photos and then just crop later in post production. But the GFX100RF lets you have your cake and eat it, too. You can apply all the crops, zooms and film simulations you want and save them as JPEGs for easy sharing. Then, if you need to go back and change something, you also have the full 100MP RAW image as a backup (though obviously, shooting both will fill your memory card more quickly).

As with the GFX100S II, the GFX100RF is a top performer when it comes to detail and sharpness. Colors are pleasing and RAW files retain high amounts of dynamic range, allowing for easy adjustment in Lightroom. And of course, Fujifilm's film simulations give you colorful, nostalgic options — like Reala Ace or the dramatic black and white look of Acros — straight out of the camera.
The GFX100RF also delivers beautiful bokeh, with the f4 aperture equivalent to around f3 for a full-frame camera in terms of depth of field (but not light gathering). Like other GFX models, the large sensor produces more dramatic images than full frame for portraits, landscapes or street shots.
Like I mentioned, things fall apart when the light dims, though. With no option below f4 and no stabilization, I relied on high ISOs to boost exposure. The GFX100RF isn't bad in this area, with controllable noise up to about ISO 8000, but that's not high enough considering the other factors. For these reasons, the GFX100RF is less versatile than it could be.
The GFX100RF can handle 4K and widescreen DCI 4K at up to 30 fps with fairly high bit rates, as long as you have a fast UHS-II SD card. It can even shoot ProRes with at much higher data speeds, but for those, you'll need to record directly to an SSD via the USB Type-C port.
Autofocus for video is decent but not incredibly fast, so ideally your subjects don't move too much. The AI-powered face and eye detection helps nail focus when filming people, but again, can fail if subjects dart around.
Video has a dreamy quality and bokeh that only a large sensor can offer. Like the GFX100S II, the GFX100RF captures video using the full width of the sensor in most modes, albeit with pixel binning that reduces quality. The sharpest video comes with a 1.32x crop, but that reduces the image quality benefits of a large sensor.
Video on the GFX100RF has one thing going for it that the photo side lacks: digital stabilization. This smooths out shakiness for handheld shots, but the excessive rolling shutter limits your ability to move the camera quickly.
Colors are pleasing and easy to adjust, particularly when using Fujifilim's F-Log or F-Log2 10-bit modes to boost dynamic range. And of course, Reala Ace, Acros and other film simulations are available in video modes to create great looks straight out of the camera.
Fujifilm's $4,899 GFX100RF is a powerful camera with incredible image quality that's hampered by a lack of low-light performance. It's also a niche and expensive product that, unlike Fujifilm's popular X100 VI, only appeals to a small group of photographers.
Its primary rival in this space is Leica's Q3, which has a smaller 60MP full-frame sensor and higher $6,735 price tag. However, the Q3 has a much faster 28mm f/1.7 lens, less rolling shutter, a single SD UHS-II card slot and up to 8K video. It also has the Leica brand cachet, which does mean something to people spending this kind of money.
The GFX100RF is fun to use, though, and introduces several innovations like the aspect ratio dial. Though it may never have a huge market, I think products like this push the industry in new directions and create conversations that draw new people into photography. So even though I'd never buy one, I'm glad the GFX100RF exists for those reasons.

AI might undermine one of the better alternatives to the Kindle
Kobo, a Rakuten subsidiary that sells ebooks and ereaders, has built its name on being a more open and author-friendly version of Amazon Kindle. However, a recent change to the company's self-publishing business has some writers worried that reputation might change. Last month, the company updated its Terms of Service for Kobo Writing Life , its publishing platform, which opened the door to AI features on the platform. With that new contract language going into effect on June 28th, authors seem no clearer on what it will mean for their futures on Kobo. For authors who haven't broken into (or have opted out of) traditional publishing both Kobo Writing Life and Kindle Direct Publishing offer a way to sell books without needing representation or a publishing deal. If they can provide their work and the information needed to make a store page — and have a willingness to serve as not only author but marketer — they have everything they need to sell their books. Agreeing to sell on one of these platforms comes with a list of conditions. The biggest is the split of sales. If an author sells their novel for $2.99 or more on Kobo Writing Life, they keep 70 percent of what they earn. On the considerably larger Kindle Direct Publishing platform, there are two royalty options — 35 percent and 70 percent — but both have a confusing litany of compounding factors , some of which can significantly reduce authors' earnings. The calculus of fees vs. exposure makes authors develop strong preferences for the platform they choose. But the terms of service under which their work is published are also important — and apparently subject to change with little warning. Engadget spoke with three authors who were surprised by Kobo's decision to experiment with AI. All of them noticed the company had published new Terms of Service because of a simple banner notification in the Kobo Writing Life Dashboard. Even now, a month after the terms were changed, the company is unable to clarify how the new terms would apply to existing work. There also isn't a means for authors to opt out. If anyone on Kobo is adamantly against any amount of AI use, their best and only option is to stop publishing there, and probably to pull their existing work from the platform. The authors we spoke to were surprised that Kobo didn't reach out about the proposed changes in advance, but also that the company was choosing to work with AI at all. "I appreciate their transparency in being candid about their use of AI," Michelle Manus, a fantasy author on Kobo's platform, wrote to Engadget over email. "What I think they vastly underestimated was the extent to which their user base dislikes AI." Kobo's new terms are explicit in saying that the company does not plan to use authors' work to train generative AI. It does, however, reserve the right to use "artificial intelligence, machine learning, deep learning algorithms or similar technologies" to "read, analyze, and process" writing for a variety of non-training purposes, including: "Enhancing the discoverability of Works" with tagging and targeted customer recommendations "Evaluating the suitability of Works" for sale in the Kobo store "Generating resources" like "creating keywords, promotional content, targeted advertisements, customer engagement strategies and other materials" "Providing recaps, reading assistance and accessibility features" Authors have taken issue with the apparent lack of recourse provided to them. What happens if a work is incorrectly tagged as one genre when its author believes it more directly fits another? Or what if the "promotional material" Kobo generates includes some kind of hallucination? The biggest issue for the writers Engadget spoke to was the potential for Kobo to deploy AI-generated recaps. Amazon implemented a recap tool on Kindle in April , using generative AI to help readers get back into a series or remember where they were in a novel, and some authors have already found examples of the company's AI inaccurately summarizing stories. "We would have immediately gone, 'Ah, okay, we see what you're trying to do, but we don't think that the thing you're suggesting is going to work to address the problem that you're trying to address," Delilah Waan, a fantasy author and YouTube creator, told Engadget. Since self-published authors tend to be more responsive to their audience, these kinds of issues could actually jeopardize that relationship. "Authors frequently get pushback from readers about plot choices, and I can only imagine the levels to which that could rise if they are receiving incorrect recaps of what happened in a book," Manus wrote. All of the authors Engadget spoke to admired Kobo's attempts to address complaints in public. On Bluesky, the company's CEO Michael Tamblyn posted a long thread getting into the logic of including an AI clause in the company's terms. Essentially, Tamblyn wrote, Kobo is trying to make the job of connecting readers with authors easier, and streamlining the moderation process that goes into maintaining the Kobo Store, all while avoiding trampling over copyright. "We are completely uninterested in creating new content using authors' books, and don't do anything that would allow us to do that," Tamblyn wrote. "And we don't want anyone else to do it either because we are in the business of selling books and would like to be able to keep doing that." Agreeing to not train generative AI with an author's work is what all professional writers have been encouraged to demand from publishers by The Authors Guild , a professional organization that advocates for writers and is currently participating in a lawsuit against OpenAI. By choosing to not train generative AI on books, Kobo is starting on the right foot. The dubious nature of what material gets fed into an AI model still leaves many questions, though. "Keep in mind, all of the models right now are illegally trained, and I mean all of the big LLMs [Large Language Models]," Mary Rasenberg, the CEO of The Authors Guild, says. "So they may be using an AI system that's not one of the big LLMs, but whatever system they're using may be based on one of the big LLMs." Kobo did not respond to a request for information about which LLM it plans to use. For work that might be misclassified or mislabelled, the company encouraged authors to contact them via its support email, which authors say has been responsive to complaints so far. The company says it has not begun testing what it describes as a "beta feature" for generating a "personalized recap" in the Kobo app. It notes that it's "not interested in doing whole summaries of books." Instead Kobo plans to make its recaps specific to each reader, around 150 words in length based on both the pages they read in their last reading session and the quotes they highlighted. Ebook platforms are taking a cautious approach to AI broadly. Authors who publish through the Apple Books platform can have AI-narrated audiobooks generated from their work, but doing so is completely optional. Barnes & Noble's Press platform doesn't currently offer AI products. Amazon's recaps are currently the most invasive use of AI across ebook markets, and authors can't opt out of them."It doesn't matter how much money we're making from Amazon. We all hate dealing with it," Waan said. She made it clear that self-publishing authors are scared of Kobo changing because it currently has author-friendly answers to most of Amazon's products. "I cannot describe how much we want Kobo to succeed, like we are rooting for them," she said. Every company seems keen to continue pushing the boundaries of where and how invasively it can implement AI. Waan's hope now is that Kobo engages in some kind of open forum with authors about its proposed uses for the technology. "I think it's really hard to decide, as an author, 'am I going to pull my books?,'" Waan said. "Because the minute you pull your books it's a whole headache, because you gotta update all the links. If you have ads running, you gotta pull them. It's not as simple as turning off a light switch." Difficult as it may be, that's a decision self-published authors will increasingly be forced to make. If you buy something through a link in this article, we may earn commission.

I just found out my Ninja air fryer has this hidden feature — and my mind is blown
If you own a Ninja Foodi Max dual air fryer (one of the best air fryers out there in my opinion), you might not realize a useful feature that's been sitting in your kitchen all along. Tucked away in a small side compartment is a digital meat probe that many owners never discover. I'll be honest, I've had my air fryer for nearly three months before I found this thing. I never bothered reading the manual thoroughly, and the compartment isn't exactly obvious. The probe itself is more sophisticated than you'd expect from something that comes free with an appliance. Unlike regular meat thermometers that you stick in and remove, this one stays in your food throughout cooking. It monitors the internal temperature and communicates with the air fryer to let you know when your meat is done. The main advantage is eliminating guesswork from cooking meat. Instead of relying on cooking times that can vary based on thickness, starting temperature, or even how frozen your meat was, the probe gives you exact internal temperature readings. This means no more overcooked chicken that's dry and tough, or undercooked meat that poses food safety risks. You can also cook different cuts of meat to your preferred doneness - rare, medium, or well-done - with confidence. The probe is particularly helpful for larger cuts like whole chickens, roasts, or thick steaks where visual cues don't tell you much about what's happening inside the meat. Check the side of your air fryer for a small compartment door. The probe stores inside when not in use. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. To use it, insert the metal tip into the thickest part of your meat before starting the cooking cycle. The probe connects to a port inside one of the cooking drawers. Once connected, you can select preset temperature settings or set custom temperatures depending on what you're cooking. Landing the number one spot on our list of best air fryers in 2024, the Ninja Air Fryer Pro 4-in-1 will fit up to 5 pounds of French fries or 9 pounds of chicken wings. And despite its 6.5 quart capacity, it has a neat compact design that won't overwhelm your countertop. With air crisp technology reaching 400°F you can enjoy crispy food cooked with little or no oil. Aside from providing crisp food, it can reheat pastries, roast and dehydrate, perfect for when you want to dry fruits and other foods. Cleaning up is a cinch with a nonstick basket and crisper plate. This feature is only available on Ninja Foodi Max Dual air fryer models that specifically include the probe. Not all versions of this air fryer come with the meat probe, so check your model specifications if you're unsure. If your Ninja air fryer doesn't include a built-in meat probe, you can purchase the Ninja Foodi Smart Thermometer ($22 at Ninja Kitchen) separately, which is compatible with certain Ninja models. There are also third-party meat thermometers available that work with various air fryer brands and models. The probe follows standard food safety temperature guidelines, helping ensure meat reaches safe internal temperatures for consumption. Now that you've learned all about the Ninja Foodi Max Dual's hidden feature and how to find it, why not explore some of our other articles related to this appliance? Take a look at how to clean an air fryer's heating element and 5 top tips when using aluminium foil in the air fryer. And if you're interested in how to restore your air fryer's non-stick coating, we've got you covered.

Rode AI-1 review
The Rode AI-1 is one of the best beginner-friendly audio interfaces out there, hands down. The AI-1 is so easy to use straight out of the box and has a foolproof design. While there's only one XLR input, this is a compact audio interface designed for podcasters and home musicians, so this should be all you need to get up and running. There are also two ¼' speaker outputs and a ¼' headphone input for live monitoring. Everything simply works as it's intended to. There's a reason the AI-1 is so well-respected in the audio world. I can't lie, though, I do wish it had just one more input for more versatility. That said, the AI-1 is only $129, so it could be a worthy toss-up. I'll discuss everything in detail in this Rode AI-1 review. Price $129 / £129 Analog inputs 1 x Neutrik XLR-¼' combo Analog outputs 2 x ¼' speaker outputs / 1 x ¼' headphone output Power USB-C plug-and-play Gain range 60dB Bit depth 24-bit Preamp Yes Weight 1.2 pounds Dimensions 3.5 x 4.9 x 1.5 inches Colors Black App Rode Central The Rode AI-1 is a beginner-friendly audio interface, and that's reflected in the price. The AI-1 will set you back $129 from Amazon U.S. and £129 from Amazon U.K., which is $300 cheaper than Rode's second-cheapest audio interface, the $489 Rodecaster Duo. However, if you're looking to save as much $$$ as possible, you might want to consider the even cheaper $79 Rode AI Micro. It's not the most versatile of devices with its single input, so I'd only recommend it for those recording single tracks at a time — if you have multiple podcast guests or want to record multiple mic layers at once, you might want to check out the aforementioned Rodecaster Duo. The AI-1 looks very simple — because it is. But simple doesn't mean boring. As with other Rode gear I've tested, the AI-1 is weighty and premium. The body is just 5 inches wide and 3 ½ inches deep, which meant it fit perfectly beside my MacBook Pro during testing. The compact size means the AI-1 will be at home in even the smallest bedroom studios. On the front of the interface is the XLR input, headphone (¼', not a 3.5mm) output, and two gain dials. There's a tiny LED that glows red or orange if your levels are too high during recording, which I thought was a great way to warn me about clipping while live. These dials are smooth and feel lovely to turn; they're sturdy and well-made, and aren't flimsy in the slightest. I had no issues jumping between the two quickly. On the reverse, you'll find the USB-C power and two ¼' headphone outputs. As the AI-1 is a plug-and-play interface, it must be plugged into your computer or laptop. It has no internal power supply. I find this to be more of a help than a hindrance, as it means the AI-1 is portable and versatile. As you might expect, the Rode AI-1 performs like a high-quality, high-caliber product. I've yet to be disappointed by Rode. On top of being an audio interface, it can also be used as a headphone amp, although audiophiles are better off looking for a dedicated device. If you have a high-quality mic, like the Rode PodMic ($150) or the Shure SM4 ($199), this is a sure-fire way to achieve near professional recording quality. Thanks to the 24-bit depth, the AI-1 provides a high-resolution sound. I didn't have these available to me during testing, so I used a $40 Behringer. Remember, if you want professional recording quality, you'll need one of the two mics I mentioned above. The Behringer mic I used was just to test the Rode AI-1, not to test mic quality. The AI-1 doesn't do anything except act as a connection between an analog device and a computer. It has a high-quality DAC, for high-quality sound. It's a straightforward, no-frills product, with straightforward, no-frills performance. If you already have one of the best microphones like the Shure MV7+, Shure MV6, or the Shure MV7i (which is actually a microphone and audio interface in one, and is one of the best microphones I've ever used), you won't need the Rode AI-1. This is an audio interface designed for analog instruments and mics. If you've used the iconic Focusrite Scarlet 2i2, the AI-1 is basically a more compact version of that. If you need 2 channels, the Focusrite is your best choice, but if you need the one, then I'd save $100 and get the AI-1. While there's little room for improvement, there's also very little room for error. The Rode AI-1 simply works. It connects up analog instruments, XLR mics, and allows clean, high-resolution recordings directly into your computer. As I've said earlier, there's very little room for error in the same way there's very little room for improvement. The Rode AI-1 knows what it is and does its one job well. Considering the AI-1 only has one XLR input, it's a little restricted in what it can and cannot do, but if you need one channel, it's probably the best compact audio interface you can get. If you want an audio interface and a mic in one, I'd check out the Shure MV7i I mentioned above. However, if you want the simplest and most straightforward option on the market, then there's nothing like the Rode AI-1.
