Use The Optical Zoom (iPhone 7 Plus)
Thanks to the secondary telephoto lens at the back, you actually have 2x optical zoom on your. All you need to do to activate is tap on the “2x” button above the shutter key. You can also swipe around to go from 1x to 10x, for finer control. Note: Anything above 2x is software zoom.
Use 4K Recording
Arguably one of the best features on your iPhone is the ability to shoot in 4K. It’s going to take up a lot of memory, but you can’t deny the footage looks amazing! From the Settings app, go to “Photo and Camera“. From “Record Video” option, switch to “4k at 30 fps.”
