i would actually love this. i currently have an xperia 1 vi but even after a year of using it i cant get used to how larger the phone is, but im also enjoying using the cameras a lot so i dont want to switch back to a smaller phone either. with something like these attachable lenses there might be more of a chance of being able to use a smaller phone again but still have better cameras when you need them
Some premium smartphones might whittle their rear camera counts down to as little as two in the future. They might still be able to compete with more lens-rich flagships with the addition of new external lenses, though. The new accessories will enhance mobile photography while avoiding the addition of much bulk, apparently.
