For the last three months I had been contemplating whether I would need the UWA of 10-24 lens for my summer travels and whether to spend $400 or so on it. This past weekend I was at Sequoia National Park. Amazing place aside, I almost exclusively shot with the 10-24, even in the crystal cave underground. All I can say is that the UWA of this lens is perfect fit for wide landscapes of the park. I'll post pictures in another thread as soon as I get them processed.
EDIT: Forgot to mention. Camera flash won't work optimally with this lens. The lens will cast a shadow in the lower center of the picture because it is so big.
