When shooting in 4K, however, the camera can’t utilize the entire sensor. Instead, it shoots from a smaller cropped area in the center. This makes lenses appear more zoomed-in than they would if they were using the whole sensor. That’s inconvenient if you’re typically shooting at arm’s length because you need an even wider-than-normal lens to capture a typical field of view. This isn’t a uniquely Panasonic problem—Canon opts for cropped 4K on many of its DSLRs—but on a video-centric model like the G100, it’s curious.
