I used the lens for portrait photography and it did a good job with nice depth of field. When shooting wildlife, was able to capture birds in flight but was a little soft when zoomed in at 300mm. I was surprised to see how well the lens performed at night photography at f/4 with good sharpness. I did not test the macro capabilities of the lens.
