I keep failing. . as if the "algorithms" of the lens are in conflict with the "algorithms" of the radio synchronizer. - there is no dust and moisture protection, no rubber skirt at the base of the mount, nothing. -when shooting for a long time in severe frost, the picture on the "open" begins to "soften" - The 2-year warranty is given by the manufacturer, apparently not by chance. Sigma lenses have ALWAYS been the worst in terms of "survivability". Poor quality control (and it's not about alignment). If you go to ebay, for example, you can easily find many offers, for example, Nikon lenses that were released over 30 years ago. If you try to find Sigma lenses that were released at least 20 years ago, you will find almost nothing. -In 2022, there are semi-official service centers that repair sigma lenses, but everything is repaired for a long time and tediously. Spare parts travel for a long time and the right one is almost never available. - Bokeh. As my nephew with -5 vision said: "When I take off my glasses, my bokeh is even more interesting." When they say the phrase in a review on the lens "well, the bokeh of this lens is a matter of taste" - it means only one thing - this bokeh is useless. (50, 85, 135mm - the same can be said about these lenses)
