Excellent glass for a reporter, naturalist and wedding artist, for the landscape it will also work, but not as good as we would like. But in fact, rarely does anyone shoot a landscape with a telephoto lens. Pros: Very fast and tenacious autofocus, works in all lighting conditions (D90), a fantastically effective stub that allows you to shoot handheld at 200 mm at shutter speeds of 1/20. Almost complete absence of HA at the edges and vignetting. Got cons: Not quite beautiful bokeh, semi-blurred bagels. Sharpness at all apertures "does not ring", but almost does not decrease towards the edges of the frame. It's kind of a pattern that takes some getting used to.
