The biggest upgrade to the HERO11 comes via a larger, higher resolution sensor. Sensors are the unsung ‘hero’ of camera performance and this new 2.5/3cm (1/1.9”) sensor delivers over 1 billion colours in 10-bit colour video at up to 5.3K resolution at 60 frames per second. It also results in 27-megapixel photos compared to the HERO10’s 23-megapixels. For the real data nerds, having the 10-bit video results in 64X more colours captured over the 16.7 million colours in 8-bit. A big leap.   GoPro has also (finally) extended the battery life of this camera, supposedly by up to 38% in moderate temperatures, compared to previous models. There’s also a water-repelling lens cover, which might mitigate some of the beading that occurs on the lens in the water — and save you from licking the lens every 30 seconds.
