Became the main standard lens. I always take it on trips. Yes, it weighs a lot, but the quality is worth it. I advise you to buy a lens hood - then the front lens will be less splattered and spattered, plus there is less chance of catching hares from the side light. Has some pros 1. Focusing speed and accuracy. 2. Sharp, contrasting. 3. The stabilizer is very helpful. 4. Possibility of manual focus correction without switching to manual mode. With its cons. A year later, when shooting up / down, the trunk began to move out a little, changing the focal length.
