The lens exceeded my expectations in terms of shooting quality, I bought the filter for 2500 on ebay without any problems, it’s not very convenient that the “focusing move” works in the opposite direction from nikona and tamrona, you have to get used to it, well, as a small appendage cover (it’s more convenient for competitors), but these are already trifles that you simply can not notice, although when you need to quickly throw up this unit, as it was noted somewhere in the article, it looks more like a reactive infantry flamethrower "bumblebee", the cover is somewhat annoying with the absence of tangible "pedals".
