In Tae Kwon Do, three-step sparring is a drill that involves one training partner executing three consecutive punches while the other training partner blocks those punches, and then counter-attacks after the third punch. First Tae Kwon Do instructors and black belt members from all across Perth practised three-step sparring during a recent training session.
Even f/2 on my 85 mm prime lens gives a good deal of sharpness if focus is correct; note the details visible in the white uniforms even though the photographs above are at greatly reduced size. The lens also renders the blurred-out backgrounds very pleasantly, and this is one of the qualities this particular model of lens (Nikkor AF 85 mm f/1.4) is well known for.
