I like the composition - the lone puff of cloud in the top left completes it and gives nice contrast of shape to the harsh lines of the structure - tops - RB

Thanks very much Bob.  I'm looking forward to getting on top of this lens.  I used to love using my Tamron SP 17mm on the old Nikon FM, and ever since seeing everyone's shots with the 10-20 I've been drooling.        Geoff

Drool no more Geoff........you're going great guns already.

LOL, thanks Wayne.     Geoff

I hope that you don't take this the wrong way Geoff, but this has a real Wayne d feel to it, with the deep shadows and deep blue of the sky.  Well taken and continue to have fun with the Siggy, it is without doubt one of their finest.  Cheers, Andrew.
