MORE FROM FORBESGoogle Issues Quality Warning For Millions Of Google Photos UsersBy Paul MoncktonEsteemed industry analyst Ming-Chi Kuo predicts that Apples long-awaited periscopic camera technology wont arrive until 2023, a year later than had been previously expected, according to a report by MacRumors. However, he did offer one important piece of good news for impatient iPhone photographers.
A periscopic or “folded” lens squeezes powerful zoom capabilities into the restricted dimensions of a smartphone by redirecting light sideways through the smartphones body via a sequence of lenses and mirrors or prisms. 
The technique has been used to great effect in rival smartphones such as Samsungs Galaxy S21 Ultra which is capable of up to 10x optical zoom. The iPhone 12 Pro Max, on the other hand, is limited to just 2.5x.

Flagships due in 2021 are expected to receive a higher quality telephoto lens featuring six elements rather than five. Additional lens elements can help to improve picture quality by reducing optical distortions which typically have to be corrected in software. Additionally, next years iPhone models are expected to feature a new “unibody” lens design, which will allow for smaller camera modules.
Despite Apples multiple patents pertaining to periscope technology, the company is clearly taking a very cautious approach when it comes to actually bringing it to market. The reasons behind this remain unknown, but while not everyone needs a powerful zoom lens, I feel the feature cant come soon enough.
Apples current flagships deliver superb camera performance but the addition of powerful optical zoom will surely deliver a big boost in the one main area where they still lag several years behind.
