I am satisfied with my copy, not counting the autofocus - I handed it over to the service for adjustment under warranty, I am waiting for the results. Some pros: Sharp starting wide open (sharper than 50/1.8 (1.4) D and G versions). At 2.8, excellent micro-contrast appears. Pleasant, soft, but at the same time quite expressive bokeh. Fast and quiet autofocus. Light weight, compact. Possibility of manual fine-tuning of focus. Cons below: There is no focus distance scale. Problems with quality control of alignment at the factory - it is possible to get a model with a walking focus that cannot be adjusted at home. That is, dips can alternate in front and back, depending on the focusing distance, the subject and the position of the stars. However, by the nature of the chromaticity, it is noticeable where exactly he is moving out. Blue - front, pink - back.
