Tiger Lily -- NEX-5 & Steinheil Quinar 135mm f2.8 @ f2.8. Click for larger.
The Steinheil 135mm f2.8 Quinar is by far the most beautiful looking lens I have. It truly is an object of art. The chrome finish still looks almost like new after so many years. It's a lens that screams quality, both in your hand and in your eye. Fortunately, its gorgeous looks is complimented by excellent optics. From wide open, the pictures are rendered pleasingly with very smooth tones. It's also has one of the nicest bokeh from the lenses I own. This lens was built with portraiture in mind, and although I haven't shot any portraits yet, I believe they will be stunning.
More pictures in the next few days.
