Actually, this is a panoramic using the Voigtlander 25mm f/0.95 (a very nice M43 lens). The 12mm remains my favorite and most useful, however the 25mm has less distortion and thus more reliable for panos like this. Kinda wish I had a Gigapan for this shot, but it happened so fast... I have a 12mm version up on my Facebook page, but wanted to post the high-res version here.... This shows the second rainbow much more clearly than the mm lens anyway (it became more brilliant after I had mounted the Voigtlander).
a magnificent shot of a double rainbow and 'supernumeraries' (seehttp://www.atoptics.co.uk/bows.htm for full explanations if you are not already familiar) and for once over a landscape worth taking on its own. Hope you didn't have to go out and buy the 12mm lens just to take it, but even if you did, it was worth it
