I just changed my focusing screen (Canon 5D MkII) from the "EG-A" to the "EG-S" allowing better manual focus control while shooting with my Samyang 85mm ƒ 1.4
Shot these pictures, five minutes later, in the pale February sun that slipped through my windows. A reflector, the sun and some vintage 50's adjustments all done in Aperture. My wife fortunately accepted to act as a model in my little experiment. I'm the luckiest guy on the planet.
