I like to use long lenses to shoot the fall and the at wide apertures, because I like the look of the bokeh. The Canon 200mm f1.8L would have been great for this, but it's semi-dead; I can take pictures with it, but it would not focus. Then I thought about the Kinoptik 210mm f2.8 Speciale Cine and it's beautiful rendering, I thought it would be a good lens to use. I was not disappointed.
There is something about the cinematic lenses that renders pictures so beautifully that I like a lot. If it were not so large and heavy, I would have used it far more often.
All pictures below were taken with the Canon 5D Mark II & Kinoptik 210mm f2.8 Speciale Cine.
