50D, 300 F4LIS, ISO 400, F7.1, 1/6400 CWA, AI Servo, monopod with Manfrotto Ball head, IS on. Crouched and crawled up to about 12 feet, bait was not used. Note that there is a piece of snow in the corner of the owl's right eye. No crop.
Great control of the whites here. You have the look, sharp eyes good tonal range, lot's to like. I have yet to have the privilege of seeing or photographing them.
