Xiaomi's 14 Ultra blew me away with its photography skills, making it one of the most accomplished camera phones money could buy when it launched. And while the 15 Ultra wasn't much of an upgrade, the company's 17 Ultra is shaping up to be one hell of a photography phone. As a professional photographer myself, I'm excited. 

The key to the Xiaomi 14 Ultra's photography prowess was its main imaging sensor. It had a 1-inch type chip that's physically much larger than those you'd find in almost any other smartphone camera. A bigger sensor can capture more light, which typically results in better dynamic range and details without having to rely as much on software processing. It's why professional cameras like the Hasselblad X2D II have enormous imaging sensors for pristine photographic quality. 

The 15 Ultra used the same sensor and while the phone had some changes I didn't like -- such as getting rid of the variable aperture from the 14 Ultra -- it maintained the overall image quality. And, like its predecessor, it was available with an optional photography accessory kit that added a camera grip and filter mount. This allowed you to hold and shoot images with the phone in much the same way you might with any compact digital camera. 

Xiaomi's two biggest competitors, Samsung and Apple, are also known for their superb camera phones and with Samsung's S26 Ultra range just around the corner, competition is fierce. But what makes Xiaomi stand out is that it truly seems to tailor its Ultra phones to professionals and enthusiasts. People who, like me, expect to control every aspect of the photo-taking process, rather than relying on automatic AI gimmicks. 

At this point I'd normally share rumors about how the 17 Ultra (the company opted to skip the number 16 to keep pace with Apple's iPhone 17 line) is going to get some key camera system upgrades that could make it the best camera phone around. But in this case, the "rumors" are what Xiaomi has already revealed when it announced the phone for the China market. Many of the key details are already known ahead of its expected launch in the UK and wider Europe (Xiaomi doesn't officially sell its phones in the US) within the next couple of months. 

Here's what's coming.

Xiaomi 17 Ultra already launched in China

Xiaomi officially took the wraps off the 17 Ultra for its native China market over the 2025 Christmas period and while some of the specs -- especially the battery -- may differ slightly when the phone goes on sale elsewhere, I wouldn't expect the camera specs to change all that much. 

On the surface, not much seems to have changed since the last generation. The main camera still uses a large 1-inch-type sensor, there's an ultrawide camera and a telephoto zoom with a 200-megapixel resolution -- not dissimilar to the 200-megapixel telephotos already seen on the Oppo Find X9 Pro or Honor Magic 8 Pro. But dive deeper and things get interesting. 

Xiaomi's launch page says that the main camera uses a LightFusion 1050L sensor, versus the Sony LYT-900 chip seen on the last two models. "So what?" I hear you ask. Well, Xiaomi explains that this new chip uses a technology called LOFIC HDR, which stands for Lateral Overflow Integration Capacitor, in case you were curious. 

What that nonsense string of words basically translates to is a sensor capable of delivering true HDR images from a single image capture. Typically, HDR images are created by combining multiple images at different exposures into one final photo with even highlights and shadows, and on HDR-capable screens, extra-bright areas to take advantage of the larger dynamic range. Most phones operate this way, but this new sensor technology promises to deliver better results with only one exposure. 

In fact, LOFIC HDR sensors could potentially see dynamic ranges (the difference between the highlights and shadows) of around 20 stops -- a significant step up from the roughly 12 to 15 stops seen on most of today's phones, and higher even than what most professional mirrorless cameras can achieve. Crucially, it achieves this at the hardware level, rather than leaning solely on software enhancements, which can often result in fake-looking images with noticeable digital processing artifacts. 

How this technology really pans out in everyday photography remains to be seen, but it's certainly been a while since I've seen significant hardware enhancements like this -- most of the photography innovations over the last few years have been software and AI-based. In Xiaomi's press release for the 17 Ultra's camera, the term "AI" is used just once. Even then, it's only referring to a certification system that aims to prove the images it takes are genuine photos and not generated by AI. I won't lie, it's a refreshing change from how most other phone companies are approaching their devices.

Xiaomi isn't the only one experimenting with these new LOFIC image sensors -- Apple is reportedly working on its own in-house LOFIC sensor, too. As is Samsung and Sony, according to GSM Arena. Evidently, this technology is making serious waves in the industry and may well become the next big thing in smartphone photography.

Then there's the 17 Ultra's telephoto zoom, which packs not only 200 megapixels of resolution, but also a continuous optical zoom that goes from 75 to 100mm equivalent focal lengths. Most phone zooms require you to select specific optical zoom levels (3x, 10x and so on) or rely on digital cropping for broader zoom levels at the expense of image quality.

Xiaomi appears to be continuing its partnership with Leica, too, calling the main camera the Leica Ultra Dynamic Camera, using Leica-certified APO optics for better image quality and offering the phone in a special edition "Xiaomi 17 Ultra by Leica" edition. It has the iconic Leica red dot logo, a custom Leica photography app, Leica color tones and a physical ring on the back of the phone that actually controls focus, zoom or exposure compensation. It looks amazing and, as a Leica shooter myself, I'm desperate to see what this phone is like to use for photography. 

Xiaomi 17 Ultra: Other key specs

Unsurprisingly, for what will be Xiaomi's flagship phone for 2026, the 17 Ultra packs top specs across the board. It runs Qualcomm's latest Snapdragon Elite Gen 5 chip, which has proven to be an absolute powerhouse in other phones we've tested. It'll also have up to 16GB of RAM and up to 1TB of storage.

The Chinese version boasts a 6,800-mAh battery along with 90W wired charging and 50W wireless charging. While I suspect the battery capacity will be smaller outside of China, I still expect the phone to offer at least a full day of demanding use between charges. It's IP68 rated for water and dust resistance and at 8.29mm thick at its thinnest point, Xiaomi says it's the thinnest Ultra phone it's ever made. 

Xiaomi 17 Ultra: Get me this Leica phone

I've become increasingly frustrated by phone cameras that lean ever harder on software-based image processing to artificially sharpen images and balance exposures using AI. The results almost always look unnatural, with the sort of fake exposures and crunchy details that scream "This photo was taken with a phone." The Xiaomi 17 Ultra appears to be doing things differently. 

The 17 Ultra instead relies on new hardware innovations for its image quality -- both in terms of its LOFIC sensor and its continuous optical zoom. Mix in all the Leica stuff and the top-end specs elsewhere and the Xiaomi 17 Ultra is shaping up to be one of the most formidable phones of 2026. And as both a photographer and Leica user, I can't wait to get my hands on it.
