Thanks Franz & Vincent. Vincent, you are absolutely right, I use it very often. It has a very good minimum focus distance (0.35m) and it creates beautiful vintage bokeh (a good example: /photo/18402790).
Very good portrait. Nowadays there are too many smooth and overly postprocessed faces in portrait photos This is realistic looking portrait. Very striking eyes and your choice of very narrow depth of field highlights it.
Pentax K-5ii, Limited 43mm, 2x Takumar. This is a close-up photo of a traffic sign, there was an exclamation mark on the sign, and I focussed really close to make a minimalist photo. This made me think about Solar eclipse.
