With a limited launch in mainland China today, one glance at the new phones fromXiaomi leaves little doubt what the device is all about. One of the biggest sensors we have seen in a phone so far is covered by a dome on the back of the phone.

People will tell you that size doesn't matter. The glass in front of the lens isn't perfect and that's not the case in the case of an imager The bigger the sensor, the bigger the space for individual cells. The cooling of the sensor could indicate a better low-light performance.

Each of the 12S series of phones has a different system. I am aware that I was making fun of Hasselblad for its integration of a phone, but in this case it makes sense. The phone might be able to make the most of its sensors if it useslenses designed by Leica.

I can't wait to get my hands on one of the cameras and see if it works in the real world, as it looks on paper.

That is a full-sized phone. That is a great lens. The image is fromXiaomi

According to the company, its lens designs greatly improve the photo quality of the camera. The press release makes it sound as if the phone has reinvented the wheel and made some pretty juicy promises.

Xiaomi 12S Ultra primary camera adopts an 8P aspheric lens, in order to address common photography issues such as flare, ghosting, and chromatic aberration, the camera module of Xiaomi 12S Ultra also adds anti-glare lens coating, lens edge ink coating, cyclic olefin copolymer material, and infrared light filter with spin coating technology. Together, these features offer a clearer overall picture that is consistent across the lens.

In addition to the advanced optical design, Xiaomi 12S Series “co-engineered with Leica” also utilizes Leica imaging profiles, inheriting Leica’s century-old image aesthetic and reproducing Leica’s tone and aesthetics with the aid of cutting-edge algorithms. For the end user, this means access to two photographic styles: The “Leica Authentic Look” and “Leica Vibrant Look”, both offering enhanced creative freedom to the photographer.

The first paragraph above states that we stuck tech in this camera that was common on compact cameras in 2005 or so, and the second states that we created some filters that have been around. The 'Leica look' is dependent on the films you use in the camera giant's legendary cameras.

The cameras themselves do look impressive, and sticking Sony's IMX989 1-inch sensors in smartphones is a hell of a feat, both from an engineering point of view and as a commitment to photography from the manufacturer.

Have you heard of the A 10? They built a plane around a machine gun that could blow up tanks and called it the Warthog. This isn't the type of optics you just slap into a phone at the last minute because the product people thought it was a good idea.

Superb low-light photography capabilities are promised by the sensors and glass. You are starting to talk about advanced camera tech if you combine that with some smart computational photography skills. The low-end compact camera category has been around for a long time, and these phones could be the final nail in the coffin.

It is wild that we are talking about a wide-angle lens and a 50.3MP camera. The most advanced set of lens/sensor combo on the market is this one. They aren't everything.

67W high-speed charging, a large 4,860 mAh battery, and smart battery management should keep you running for a while. The phone is powered by a new mobile platform. A cooling pump that uses a capillary network to pump cooling liquid around and keep things from overheating is included in the 12S Ultra.

The phones are only available in mainland China and the starting price is around $900, $700, and $600. It is not known if or when these will make it outside of the country.
