The only complaint from my side goes to the 5-year warranty on the part of Tamron.
First one is thrilled one reads the fine print, however, it soon becomes clear that one has to fall apart the lens before formally that you can benefit from it. The most extreme things is in fact covered by the guarantee. Among them, unfortunately, dust and sand in the lens. Who ie clothing fibers or sand is sucked out of the holiday into the lens, which has been unlucky, warranty does not apply. Very unfortunate.
