>>4496620>>4496645UWA is absolutely okay for landscape but shouldn't really be the default choice. However, the 10-22mm range includes the 24-35mm section which is normally the ideal spot for landscapes AND UWA lenses tend to have less distortion than GP zooms in that range.
You can also go for a prime which is often better but also good luck getting the framing right.
>>4496650Literally my favorite lens now and most used. I personally think anything 20mm and wider counts as UWA but technically <24mm is.
