F/2 shot of my son's guitar case resting on chair infested with cat's fur. I had to apply substantial contrast...pic taken from 6' had a bit of the haze the lens is noted for at focus distances under 10'. Still, very sharp edge to edge...notice the detail of the cat's fur and the grain and stitches on the case. A bit of corner flare reflecting the window light shows the len's lack of multicoating due to age. Handheld and high-iso.
