will be heading back here in the spring with a d800 and maybe the 15 2.8 :)

c'est super

Thanks. The 21 is sure in a league of it's own.

But that's a mighty nice shot to show for all your gruel. I love the ZF 2.8/21mm, to my mind, and supported by your beautiful pano, it may be one of the all time great wide angle lenses for the 35mm/FX format (D)SLR, and can hold its own with the Leica and Zeiss rangefinder lenses, no trivial feat.

I have been gone for for a few days out in the alpine lakes wilderness in Washington state. Was heading to the Enchantments which is right above the ridge line there. Snowing and raining confined us to our tents. On the day out, we woke up to a clear sky and this is what I took. Hand held 7 images stitched. Nothing else to show for this grueling trip :(
