Apple is holding a special launch event on September 7, where the company is expected to announce its new iPhone 14 lineup. In typical Apple fashion, the tech giant didn’t say much in its invitation about its iPhone 14 event. The invite describes the September 7 event as “Far Out” with a graphic depicting an Apple logo floating in space, hinting at improvements made to the iPhone’s camera. The teaser words “far out” could mean anything, but it opens up possibilities of a periscope lens on at least one of the high-end iPhone models slated to launch in 2022. But what is a periscope lens, and why the time has come for Apple to increase zoom capabilities on the iPhone?
The iPhone 7 Plus was the first iPhone to feature a 2x optical zoom. On the iPhone 13 Pro and iPhone 13 Pro Max, users get 3x optical zoom in and 2x optical zoom out when shooting photos (totalling 6x optical zoom range). Remember putting a high optical zoom lens in a device as slim as an iPhone is a lot difficult. This is the reason why the current-generation iPhone models are limited to 2x optical zoom. A periscope zoom lens can change the zoom capability of a smartphone.
To understand this concept better, think of how periscope – the word associated with submarines – works. The periscope is a rectangular viewing tube with viewing windows at the top and bottom. Both ends of the periscope’s structure are fixed at a 45-degree angle. A periscope camera works similar to submarine periscopes. Instead of light entering the camera directly through the lens and then onto the camera, the periscope system takes the incoming light and reflects it 90 degrees through the lens array and onto the sensor, without making the phone any thicker. By doing that, it is possible to achieve a lossless zoom beyond 5x that would otherwise be not possible with a regular lens enclosure.
Definitely, the periscope lens camera technique can greatly improve the camera experience and the finest example is the Samsung Galaxy S22 Ultra, which packs a second, 10x optical 10MP telephoto camera at f/4.9 with 1.12μm pixels. In fact, the Galaxy S22 Ultra, just like its predecessor, can achieve 100x Space Zoom. High-end phones from Oppo, Vivo and Huawei also feature long-zoom cameras. No wonder a periscope zoom lens is seen as a huge selling point on high-end smartphones. Even though not every user understands what a periscope camera technology can achieve but there are benefits of long-range zoom cameras on phones. Enthusiasts and photographers are the core audience who would want to have a phone with a pericope zoom lens.
