The iPhone 11 Pro phones come with triple 12MP Ultra Wide, Wide, and Telephoto cameras. The iPhone focal length of the lenses are 1.54mm, 4.25mm and 6mm. Their 35mm equivalent focal lengths are 14mm, 26mm, and 52mm, respectively. Cinematographer Newton Thomas Sigel gives a great explanation of the different effects of wide, normal and telephoto lenses.

iPhone 11 Pro Max Ultra Wide Camera – lens focal length 1.54mm (35mm equivalent: 14mm)
iPhone 11 Pro Max Wide Camera – lens focal length 4.25mm (35mm equivalent: 26mm)
iPhone 11 Pro Max Telephoto Camera – lens focal length 6mm (35mm equivalent: 52mm)

In the late 1970’s, I used the Nikon 13mm f5.6 lens on the Nikon F2 camera. The Nikon 13mm lens had a 118 degree angle of view and in its time, it was remarkable in that it was a rectilinear lens. The extreme angle of view opened up new creative possibilities in all types of photography including indoor, architectural and landscape photography.

The iPhone 11 Pro’s Ultra Wide camera angle of view is 120 degrees. When using the Wide and Telephoto cameras with iOS 13.1 camera app, the Ultra Wide lens enables a preview of what is outside the frame. This outside the frame information is also captured in the Wide and Telephoto cameras to enable post processing cropping without losing image information. This setting can be enabled in Settings -> Camera -> Photos Capture Outside the Frame.

  1. I just imported my first set of photos taken w/my iPhone 11 (not the Pro or the Pro Max). I was stunned to realize there is no “normal” (~50mm) lens on my iPhone 11. Only wide and ultra-wide on the back, and wide on the front. As a result, it’s impossible to get a photo of a person that doesn’t look vertically squished and distorted! I didn’t want to spent the extra $300 for that third lens, but without it, I can’t take any pictures of people that don’t look terrible and severely distorted!!!
