iPhone 7 Plus Dual-Camera Gives 2x Optical Zoom and Shallow Depth of Field

Here are a bunch of officially released pictures taken from iPhone 7 and iPhone 7 Plus.

Long rumored iPhone 7 and iPhone 7 Plus have been announced officially with almost everything as speculated. The most hyped feature of course was its dual-camera ever since before Huawei introduced its dual-camera setup with Huawei P9. Finally Apple’s dual-camera configuration has been revealed that comes with the bigger iPhone 7 Plus.

With Huawei P9, we learnt that how a color sensor combined with a monochrome sensor can produce much better image detail as well as if implemented correctly the shallow depth of field could be real interesting to make quality bokeh effect from a smartphone with two camera modules. HTC One M8 has also done the depth-map with its dual-camera setup but it wasn’t implement as gorgeously as it didn’t impress many. Apple has now used it another way which could be really useful.

iPhone 7 maintains the same 12MP camera with its predecessor. However the new model comes with several new features which were not present previously in iPhone 6s. Optical Image Stabilization (OIS); sensor readout is about 60% faster; six-element lens is wider with the aperture f/1.8 and the true-tone flash has 4 LEDs for more powerful luminance.

The dual-camera setup comes only with the bigger iPhone 7 Plus and both the cameras use the identical 12MP image sensors. What distinguishes them are the lenses on top of them. One is the standard 28mm equivalent wide-angle lens with f/1.8 aperture similar to the iPhone 7’s camera. The 2nd camera on the iPhone 7 Plus is equipped with a 56mm telephoto lens with f/2.8 aperture. With that, Apple focuses on to provide quality optical zoom feature to the users. With this dual-camera setup when you use the zoom feature iPhone 7 Plus switches from the wide-angle unit to the telephoto unit providing 2x optical zoom.

Then from 2x optically magnified image (the telephoto image), iPhone 7 Plus provides further 10x digital zoom which is supposed to be better than other smartphones which provide only digital zoom feature from the widest angle. In video recording digital zoom can go up to 6x.

Another feature of the iPhone 7’s camera is depth-of-field that allows you to keep faces sharp while creating a blurred effect in the background – that’s bokeh effect. The dual-camera system on iPhone 7 Plus uses advanced machine learning to make your subject sharp while creating out-of-focus blur in the background. This feature is activated Portrait scene mode but it will be provided later via a software update.

According to Apple its new ISP is faster than before and can complete tasks like noise reduction, image stacking and exposure control in only 25ms (approx). The Live Photos (moving photos) are now captured using video image stabilization and first time Apple has iPhone 7 capable of saving RAW data – thankfully in the DNG format and not their own standard. 4K videos support is there and both 1080p and 720p support slow-motion recording. Not to mention that on the front now there is 7 megapixel Face Time camera which is out of the topic here.

Just go ahead and take a look at the official iPhone 7 camera samples below.
