I took it for a test at the box office - I liked the result, I had to go to the store for a new one. I chose one of the three requested copies, although I was pleased that all three were of decent quality (the difference is minimal). I tested it in the salon for a long time and meticulously according to the templates I took with me (all three had a small BF - in real conditions everything is ok). The copy got sharp with f1.4 (for the rental it started with f2.2 and more soap). Lenses made in China and boxes in the Czech Republic.
