Tried the 85 1.4 on a 36mm extension tube today. This one is at ISO 1600, f4, -0.7 ev, 1/320 due to fast moving subject. No post other than resizing to what you see here. D50 in aperture priority mode. Shot as JPEG. This was the only one of more than a dozen that placed the DOF right where I wanted it. Silly kid.
