Xiaomi has announced the latest entry in its phenomenally popular Redmi Note series and, just as the Redmi Note 7 heralded a flood of 48-megapixel phone cameras earlier this year, the Redmi Note 8 Pro is among the first with a 64-megapixel sensor. Realme semi-revealed its XT with the same sensor a couple of days ago, but Xiaomi has now made a full announcement, so feel free to debate among yourselves as to who was truly first. Why would you want a 64-megapixel camera? Well, as with 48-megapixel phones, it’s generally not so you can shoot at full resolution. Both sensor designs use 0.8μm pixels that are grouped together in fours for better light sensitivity that’s supposedly equivalent to 1.6μm pixels. Using that technique, a 48-megapixel camera will produce 12-megapixel images, while Samsung’s GW1 64-megapixel sensor will get you 16 megapixels of usable resolution. It’s also physically larger, so it’ll capture more light overall. In some situations, like extremely bright lighting, you might want to shoot in 1:1 64-megapixel mode, but the 16-megapixel mode will be more broadly useful. Realme has provided sample 64-megapixel images that do indeed resolve a lot of detail in certain...
