Beauty Biokor-S 4.5cm f1.9 In Use

This lens turns out to be quite nice.  I mounted it on my A7 for about a week and shot a few hundred frames. I enjoyed it as a walk-around lens.  The Pentax helicoid provided a very versatile focus option from extreme closeup to infinity, all without having to add extension tubes.  The funky looking honey-combed defuser panel for the light meter cell adds a touch of vintage charm.  The only negative is the sticky aperture ring, and I did have to use it a few times for some pictures with a bit more depth of field.  Not a big deal, but an annoyance just the same.

I like the smooth bokeh from this lens.  Some very slight swirl when pictures are taken at certain distance, but overall very pleasing.  It flares quite easily, like most old lenses.  A hood helps a bit but not at all situations.  Overall, I think it was worth the effort of the conversion.  This lens produces nice results.
