At the Mobile World Congress (MWC) in Barcelona, realme revealed a concept phone called “Ultra,” featuring an interchangeable lens system. realme combines the Ultra prototype with two lenses: a 73mm and a 234mm—both have manual focus and aperture rings, with the 73mm notably resembling Leica’s design. However, the 234mm lens, while large, makes it clear that this setup would benefit from a tripod to maintain stability. The system also includes two lenses inspired by the Leica M-mount, though realme clarified that there’s no direct partnership with Leica. realme solely developed said two lenses and the use of M-mount was mainly due to its compact size and flexible focal lengths. Notably, this approach differs from Xiaomi's Modular Optical System, which uses magnets and proprietary tech to attach lenses to its Xiaomi 15 prototype. The Ultra's larger 50-megapixel Type1 CMOS sensor outperformed the iPhone's telephoto lens, though the comparison isn't entirely fair since the iPhone uses a much smaller sensor.
