Very sharp at 2.8! For me, this is one of the most important principles. When I was choosing a lens, I reviewed a bunch of conflicting information, even somewhere in the depths of my soul I was ready to forgive the blurryness in the frame, like in the first version, still the zoom and all that ., but when I put it on my 3 nickel, I was shocked! Now I consider this lens ideal for myself - the most popular focal lenses with sharpness like those of fixes. Now the price seems very reasonable for it. As for the lens hood, I also really like it, compact, I don’t understand the criticism addressed to it.
