In the last decade, cell phones have made huge leaps forward in technology and capability. It's simply incredible what they are capable of these days, and the amount of processing power and features they have would have been unimaginable not so long ago. The latest iPhones are capable of shooting beautiful images and video up to 4K at 60p. Further, still, the iPhone 8 and X are capable of filming at 240 fps when shot at 1080p, which is very impressive indeed. Both of these features are currently not available in any other similarly priced phone, DSLR, or even most mirrorless cameras. Even popular DSLRs like the Canon 5D Mark IV and Nikon D850 aren't able to shoot at the same frame rates as the iPhone. The question that many people ask is, why?
In a recent video, Max Yurev explains why he thinks this may be the case and discusses how the processing power in the latest iPhones enable these amazing features. Yurev describes how many DSLRs currently do not have the processing power to be able to perform at those levels and, although the sensor size plays a part, the processor is ultimately the reason.
Cameras such as the 5D Mark IV need to heavily crop the sensor in order to shoot at 4K and, even then, can only do so with a much older, inefficient codec. Other cameras such as the Sony a7R II and Sony a6500 are able to shoot without cropping the sensor. However, they generate far too much heat, causing them to inevitably shut down. Currently, only the Panasonic GH5 is able to shoot 4K 60p using the whole sensor.
The iPhone may not be able to fully match the quality, look, and feel of video coming from a camera with a much larger sensor, but it's still very impressive to see these features in a very pocketable and capable device.
