John Gruber: A telephoto is only good for photography, in that sense. The ultra-wide lens is a tool with additional utility beyond capturing photos you want to keep in any artistic or emotional sense. You can always grit your teeth and use digital zoom if you don’t have a telephoto, but you can’t fake going wider or, importantly, closer. The minimum focal distance of the iPhone 17 Pro 1× lens is 20 cm. The minimum focal distance of the iPhone Air 1× lens is 15 cm. Those extra 5 cm make a difference, but the iPhone Pro’s 0.5× lens has a minimum focal distance of just 2 cm. It can focus on pretty much anything you put in front of it. The iPhone Air’s 1× lens can’t do that. With Apple Intelligence and Siri AI, taking macro photos of objects and text, simply to ask Siri or another chatbot about them, is increasingly important. A 0.5× and 1× lens can also be used to shoot 3d video for the Vision Pro.
