bluetsunami, that bokeh is fabulous, 2nd from last; some people say the 50/1.7 is a little nervous but I love the 'Ridley Scott' look this one has, and we await the spring version of the 'two trees' ;~)
inglis, I think cold places are the most beautiful, the earth is pared back to its true self...
Those mountains are around 6000m, 15-20kms away, the shots are from about 4700m, about 100-200mm. The effect of the 'silky' shot is due to intense UV. The lens tends warm, a soft orange, but is easily handled and has its own signature, like all the CY lenses. Vignettes a bit too, like many CY zooms. I love the greens and autumn colours on this page.
