First question. Post your settings. And I'm sure you have a nice fancy tripod too I can never get mine tack sharp like yours or ever remotely as nice. I am always battling with my tripod and end up just saying screw it and free shoot.
I was thinking that today that I should post my settings so I have no problems doing so. I will start doing that. As for the tripod or use a manfrotto but a lot of the shots I'm putting the lens right on the glass
