We don\u2019t have any announcements on iPhone 14 yet, but we are already hearing leaks about the 2023 iPhone models. Right now, the latest one we have is about iPhone 15\u2019s upcoming feature\u2014periscope lens for better optical zoom. Although analysts believe this technology would be exclusive to the 2023 Pro models, Kuo claims only the larger iPhone 15 Pro Max will come with the new lens. So, what does the latest rumor on iPhone 15 2023 models say?\u00a0 \u00a0Latest iPhone 15 rumors\u00a0\u00a0 Speculations around iPhone getting a periscope lens have been around since early 2020, with analyst Ming-Chi-Kuo first mentioning the possibility. Initially, he said that a periscope lens would be an iPhone Pro feature. However, his recent claims say that the lens type will debut in a Pro model of the iPhone 15 series\u2014a prediction backed by analyst Jeff Pu as well. Most likely, Apple will continue offering four models in 2023. These are: The 6.1-inch \u200ciPhone 15\u200c, the 6.1-inch \u200ciPhone 15\u200c Pro, the 6.7-inch \u200ciPhone 15\u200c Max, and the 6.7-inch \u200ciPhone 15\u200c Pro Max. In his Medium blog, Kuo wrote how he believes that the periscope lens will be exclusive to the 6.7-inch Pro Max device, with the 6.1-inch Pro model keeping the telephoto lens for optical zoom.\u00a0 \u00a0How does the Periscope lens work?\u00a0 This is how the periscope system works: In a periscope system, light entering the telephoto lens is reflected by an angled mirror towards the camera's image sensor. The change in direction in which the light travels allow for a longer folded telephoto setup inside phones, enabling users to zoom in further without any blurriness. Largan and Genius are expected to be Apple's main suppliers of such a lens in 2023.\u00a0 There are already some Android smartphones with periscope lenses. Samsung's Galaxy S22 Ultra for instance features up to 10x optical zoom and 100x digital zoom. With the addition of a periscope lens, the \u200ciPhone 15\u200c Pro Max would follow suit. Kuo says the 1\/3" sensor will have 12-megapixel resolution with f\/2.8 aperture and up to 6x optical zoom, with sensor-shift stabilization. For context, iPhone 13 Pro models are limited to 3x optical zoom.\u00a0 \u00a0What does the future hold?\u00a0 Looking ahead, Kuo also believes both \u200ciPhone\u200c 16 Pro models in 2024 will use the same or similar periscope lens as the one used in the \u200ciPhone 15\u200c Pro Max, with Apple continuing its trend of setting apart standard and Pro models by reserving certain higher-end hardware features for the latter.\u00a0 This year, in 2022, Apple is expected to introduce improvements to the telephoto and wide-angle lens on its \u200ciPhone 14 Pro\u200c models. Kuo says that Apple will upgrade the telephoto camera from a 6-element lens to a 7-element lens. Kuo also believes that the 2022 Pro \u200ciPhone\u200c models will feature a 48-megapixel Wide camera, which would be a major improvement over the current 12-megapixel camera, and 8K video recording capabilities that will allow iPhone-recorded videos displayed on an 8K display or TV to provide \u201ca better user experience.\u201d\u00a0 Read Also :\u00a0Twitter sues Musk over $44bn takeover deal; Why did he back out?
