I had a chance to use the new Sony A99 camera and gave it a try at ISO1600. These were very low light and I could have held the camera steadier.... or could have turned the Steady Shot back on.
These are with either the Zeiss 24mm f2 or the Zeiss 85mm f1.4 both wonderful lenses that I would suggest to everyone who enjoys top gear.
