During Mobile World Congress 2026, I was already blown away by Xiaomi and Leica’s incredible Leitzphone that can take pro-level images, but Tecno’s concept might take things even further.
By using various modules that snap onto a more standard phone body, this concept device can morph into various forms, including a huge zoom-lens-wielding camera phone.
The Tecno phone’s core is basically a superslim Android phone with a couple of connectors on the back. The connectors allow it to interface with various modules that the company had on display at its MWC booth in Barcelona. As a keen photographer, I was naturally struck by the giant zoom module.
This accessory has an image sensor, a interchangeable lens mount and even a grip.
It’s not just a zoom lens that attaches to your phone’s existing camera; it’s a complete camera module in its own right.
There’s a large image sensor sitting behind that lens, with physical camera controls seen to the side. It basically turns the phone into a proper compact camera, using the display as the viewfinder. Cinema camera-maker Red promised something similar with its Hydrogen One back in 2018, but the product never properly came to light.
Here is a sideview of the camera lens mount module attached to the phone.
The zoom lens itself is pretty huge, but since it’s removable — like lenses on a mirrorless camera body — Tecno would presumably offer a few different focal length options. It would let you use a smaller lens if you didn’t need quite as much zoom, but still wanted to take advantage of the bigger image sensor and physical controls.
The phone unit itself is very slim, but it only really needs a minimal camera setup and a small battery.
The idea is simply that you’d add the camera unit, the much larger battery pack, or whatever other modules they create, which would then transform the phone into whatever you need it to be at that moment. They had accessories for a 3x camera lens, a wireless microphone you clip to your clothes, a wallet and even a speaker.
It’s a neat idea in theory, but Tecno says this is strictly a concept right now, so I don’t have much faith that it will be a real product I can get my hands on.
Last year, Xiaomi launched an external camera unit that magnetically attached to your phone, and I loved the device’s quality, but, like many other MWC concepts, it didn’t materialize into a real product.
