Recent leaks have revealed that Apple is considering integrating a single - lens reflex (SLR) camera - inspired 'teleconverter' design into the iPhone 18 Pro. This move aims to boost the lens's equivalent focal length and deliver superior optical zoom performance. Should this technology be adopted, it would mark a substantial leap in the iPhone's telephoto capabilities. In particular, in scenarios like capturing images of the moon and concerts, the level of detail clarity is anticipated to be on par with that of professional cameras. The imaging system of the iPhone 18 Pro has undergone a notable upgrade. It is set to be equipped with a 48 - megapixel main camera featuring a variable aperture, along with a periscope telephoto lens. The main camera allows for aperture adjustments ranging from f/1.4 to f/2.8, and the periscope telephoto lens supports 5x optical zoom. When combined with the proposed 'teleconverter' design, this setup will effectively overcome existing optical limitations and significantly elevate the overall photography experience for users.
