I have several versions of this lens, single-coated and MC, all-metal and rubberized focusing grip. All behave similarly, and all are pretty decent performers, especially for portraiture wide open and at f/2. Flare resistance is low in all of them including MC. _________________ List of lenses |

This one is certainly an excellent lens.

Cosina built some excellent, some good, some average, and some mediocre glass. For example, if you compare its plastic-fantastic 100/3.5 Macro with Voigtlander-branded (but built by Cosina) 125/2.5 Macro, you'll see both sides of the spectrum. _________________ List of lenses |

Plastic fantastic 100mm f3.5 macro made by Cosina is really a great lens if you manage to get past the fact that the barrel is plastic. Hands down my favorite macro on mirrorless. _________________ Many lenses and some film bodies for sale here: http://forum.mflenses.com/canon-fd-minolta-md-c-mounts-m42-pentax-and-more-t50465.html
