This cannot be ordered! You have to come to the store and choose a copy without back and front focus. There are problems with this. Personally, mine gives a front of 5mm, but I decided that it was not scary, besides, it was the best of the 5 tested in the store. The aperture blades are not rounded, which is why at 2.8, for example, the bokeh will be hexagons. Specific, but I can not attribute it to the shortcomings. At 1.8, you need to focus with your hands, or 'wisely' or better 2 in 1. It is problematic to place in a photo bag, so as not to hang out.
