After sharing a collection of photographs taken with the iPhone 7 Plus at the Titans-Vikings game yesterday, Apple CEO Tim Cook this morning tweeted out another group of photos captured with Apple's new 5.5-inch iPhone, now providing a few examples of low-light photography.
The new set of photos were taken by ESPN photographer Landon Nordeman during the U.S. Open. According to the publication, "the autofocus and exposure performed exceedingly well in various lighting conditions -- so that even with one hand, he could get the shot."
Better low-light photography was emphasized by Apple in the new ad for the iPhone 7 and iPhone 7 Plus. The improved conditions in low-light situations, as well as crisper and brighter photos, come at the hands of the iPhone 7's 28mm 12-megapixel camera with optical image stabilization, a wider f/1.8 aperture 6-element lens, wide color capture, and a new Apple image signaling processor.
The iPhone 7 Plus has all of these features, with the addition of a second 12-megapixel 56mm telephoto lens with an f/2.8 aperture, enabling a new and highly-detailed 2x optical zoom ability. Nordeman's style -- described as "surprising moments from unique perspectives, using color and composition without distracting his subjects" -- was enhanced thanks to the portability of the iPhone 7 Plus, which provides various DSLR-quality features without needing a cumbersome camera system.
Yesterday, an enterprising Redditor used EXIF data from the photos shared by Sports Illustrated to derive the sizes of the main and secondary camera sensors on the iPhone 7 Plus, also using information known about the sensor on the iPhone 6s. According to the user, the main lenses on the iPhone 7 and iPhone 7 Plus are nearly identical in size to the one on the iPhone 6s.
The actual focal length of the main camera is 3.99mm, derived from one of the photos EXIF data. A 1/3in sensor has a crop factor of 7.21, and the iPhone 6S' sensor is 1/3in. The math is below:
iPhone 6S (1/3in sensor) = 4.15mm x 7.21 = 29.92mm for a 35mm equivalent lens.
iPhone 7 Plus main sensor = 3.99mm x (7.21?) = 28.7679mm, very close to Apple's claimed 28mm.
iPhone 7 Plus telephoto sensor = 6.6mm x (8.6?) = 56.8mm, very close to the claimed 56mm as well. For a 1/3.6in sensor, the crop factor is 8.6.Edit: For context, a larger sensor size allows for shallower depth of field, or the use of bigger and/or more pixels. Generally, the smaller the sensor, the worse it performs; however, we all know Apple pushes out some quality components so this doesn't necessarily mean it's true. Example: The 6S cramming 4million more pixels, and its pixel size being reduced from 1.5microns to 1.22microns to retain the same 1/3in sensor size, yet, they kept image noise performance still similar to the 6, basically having more detail at almost no cost.
The first iPhone 7 pre-order customers have already begun receiving shipment notifications regarding their incoming orders, which are preparing to arrive this Friday, September 16. Also launching this Friday is the Apple Watch Series 2, which the company announced alongside the iPhone 7 last week in San Francisco.
