I'm a little disappointed with my tripod when using a bigma and 2x teleconverter. I set timer to 10 seconds and watch the view finder and when the shutter snaps the camera shakes a bit. I have the Gitzo 1228 with Acratech ball head. Am I asking too much of this setup to shoot 1000mm?? I sharpened this a lot and croped a bit but it is just not sharp and some of the others you can see the double image because of shake.
