Keltlab,
At first I suffered sharpness issues. It came down to several things.
1) Needed the dock to adjust center of focus point, mine was front focused from the factory.
2) Be mindful of the elements around you.
Our mornings right now are clear but the grass is wet with dew. When the sun comes up, the water starts to turn to vapor and don't really see it by eye. But shooting the sheep 300-500' away at 500-600mm they are soft. Shoot them in the evening and they are sharp.
3) The IS does a good job, but my better steadied on something hand held shots are following aprox 1/4 shutter speed to focal length (500mm = 1/125) - those I steady myself and lens against something.
True hand held shouts with no support are roughly 1/2 shutter speed to focal length.
Thanks for the advice and the details! I'll see what I can do and hopefully post some images to the thread!
