Tomorrow, September 22, the iPhone 15 lineup will go on sale after having been launched on September 12. However, the chances of you being able to grab an iPhone 15 Pro Max are quite low unless you were able to pre-book it since the model has officially sold out and only a limited supply is available for retail stores. Part of this popularity is the new 120mm tetraprism lens that adds a 5x optical zoom capability to the smartphone. However, many have been questioning why Apple did not extend it to 10x optical zoom like its rival Samsung Galaxy S23 Ultra. Finally, the company has responded to the queries and given an explanation.
