Shoot video, 4K & slow motion
Every iPhone model currently on sale allows you to record both 4K and slow motion videos.
There are some notable nuances between the models, though, that you should be aware of. The iPhone SE, 6s, 6s Plus, 7 and 7 Plus all let you record 4K videos at 30fps (frames per second). However, if you want silky smooth 60fps 4K videos, you’ll need to plump for the iPhone 8 or higher.
Slow it down
There are similar differences when it comes to slo-mo. The SE, 6s, 6s Plus, 7 and 7 Plus can record 120fps slow motion videos at 1080p resolution, but if you want to slow things down to 240fps, you’ll have to drop the resolution down to 720p. There are no such worries with the 8, 8 Plus and X, which can record 240fps slow motion videos at the full 1080p resolution.
There are other things to consider aside from 4K and slow motion capability. From the 7 onwards, the power of the camera’s zoom has been improved to allow for better digital zoom and, in the Plus model, optical zoom for the first time. The rear cameras on the X also feature better video stabilisation, and an improved f/2.4 aperture on the telephoto lens.
