Help with Zeiss 24mm!

Sean, those last two are quite nice, and especially the last one.

To nush, the last two are photographs that would be hard to capture with one of the zooms.  The Sigma 19mm could come pretty close, but one of the things that makes those photos work well is that Sean was able to keep the ISO low.
