Apr 18, 2018 · As we zoom in, the telephoto lens helps the iPhone 7 Plus retain some of the more nuanced pockmark wall details where the iPhone 7 blurred them together, but both returned fairly similar imagery overall.
- Zoom With The 2x Telephoto Lens. The regular iPhone 7 camera has the standard wide-angle lens, similar to previous iPhone models. But the iPhone 7 Plus has two separate rear-facing camera lenses.
- Beware Of Digital Zoom. As well as the 1x/2x zoom option, the camera app also has a digital zoom feature which allows you to “zoom in” even closer. It’s easy to activate – simply touch the 1x button with your finger and drag to the left.
- Create Shallow Depth Of Field With Portrait Mode. Up until now, one of the main limitations with the iPhone camera has been that you couldn’t control the depth of field like you can on a DSLR camera.
- The Importance Of Background When Using Depth Effect. The Depth Effect feature in Portrait mode works best when your subject is far away from the background, and when there’s something in the background to begin with.
Oct 28, 2016 · Unlike other smartphones that use their dual cameras to capture depth information and blur the background or capture monochrome image info for better clarity, the iPhone 7 Plus uses its second 12MP camera to deliver lossless, up to 2x optical zoom.

With the launch of the iPhone 7 and 7 Plus, Apple improved its already excellent cameras from the previous generation, and added a variety of new features that it hopes will continue to make the iPhone the world’s most popular camera. While some of the new features are reserved for the 7 Plus, both cameras have received plenty of upgrades – includi...
The iPhone 7 Plus features additional capabilities based on its dual-camera architecture. It uses the second camera for a 2x optical zoom and computed depth information. Its new Portrait mode is designed to use the depth information gleaned from analyzing the images from both of its cameras to selectively blur image backgrounds while keeping the fo...
The additional rear camera on the iPhone 7 Plus is quite a bit different from its primary camera. It maintains the 12MP resolution, but features a longer focal length lens (56mm equivalent), which in turn drives the need for a slightly smaller aperture(f/2.8), as well as a smaller sensor size (about 2/3 as large) to kep the iPhone 7 Plus as thin as...
Lack of a true optical zoom has been a glaring limitation of smartphone photography. Virtually all smartphone cameras are equipped with a relatively wide-angle fixed focal-length lens, which means if you want to take a closeup of a subject, you need to either move closer to the subject or zoom in digitally (i.e., crop to compose). The iPhone 7 Plus...
We’ve seen that the longer focal length of the lens on the 7 Plus provides more details in telephoto images captured in bright light. However, there are trade-offs inherent in Apple’s dual-camera design, because the secondary camera has a smaller sensor and slower lens (smaller aperture) than the primary camera. It also lacks Optical Image Stabiliz...
The disadvantage of the increased detail from the telephoto lens is a slight increase in noise due to the smaller pixel size. We compare zooms by setting the camera zoom to a 50mm and 85mm full-frame equivalent field of view by using whatever zoom method the camera supports (optical, digital, or hybrid) so that the full target is framed. We then ev...
A major differentiator of high-end standalone cameras such as DSLRs, when compared to smartphones, is their ability to let the photographer create images where the subject is razor-sharp, and the backgroundis pleasantly blurred. Typically, this shallow depth-of-field effect is achieved by coupling a wide-aperture lens with a large sensor. Conversel...
The iPhone 7 Plus can’t actually create the effect of depth with its optics because of its small sensors and short focal length lenses. However, by using images taken simultaneously with its dual cameras, it can in fact create a simulated depth effect in real time. The iPhone first estimates the distance of each object in the scene, after which it ...
Because the depth map is only an approximation, artifacts are created in areas with fine details in areas of depth transition, as illustrated by this comparison of the optical blurring from a full-frame DSLR with the synthetic effects created by the iPhone 7 Plus: Shooting in low light also causes issues when the iPhone 7 Plus is set to Portrait mo...
Another issue in evaluating Bokeh is how well the subject in an image is isolated – which helps attract attention to it. Physically shallow depth-of-focus lenses do this automatically because of their optical properties. The iPhone 7 Plus can simulate this Depth Effect when you enable Portrait mode. However, this simulation blurs foreground objects...

Nov 7, 2016 · Combined with digital zoom, you can drag the zoom slider in the camera app up to a 10x magnification. At F1.8 the six-element lens in the wide-angle camera comes with a faster aperture than the 6s Plus and optical image stabilization is on board as well.
With the built-in 2x telephoto lens of the iPhone 7 Plus, you now essentially have a 2x optical zoom feature. Optical zoom means that it’s the lens, rather than software, that’s zooming in. And this results in much higher quality zoomed in images.
