The Razr Fold’s cameras will have to do more than what we’re used to seeing on the flip-style Razr smartphones, which have underwhelmed in the past. Fortunately, it looks like it could be a very capable smartphone camera. The main 50-megapixel sensor has a f/1.6 lens and 3.5 degrees of optical image stabilization. It’ll also work alongside a multi-spectral 3-in-1 light sensor to improve color accuracy. The Razr Fold’s ultrawide camera has a 50MP sensor, a 122-degree field of view, and support for macro photography. The 50MP periscope telephoto camera can reach up to 3x optical zoom and 100x SuperZoom, through image cropping and AI-boosted image processing. And finally, there are two selfie cameras: a 32MP internal camera that can record up to 4K video and a 20MP external selfie cam, both with a f/2.4 lens.
