About a decade ago, when even the best camera phones typically only came with a single camera on the rear, I used to carry around a clip-on wide-angle adapter. While it certainly degraded the image quality somewhat, it gave me the added versatility that I craved.
A few years later, ultra-wides started appearing on more and more phones – and it wasn't long before my little clip-on lens adapter felt like a relic of the past.
