Thanks Jim, Tony, & Mark.

Mark, I don't think it was camera shake. I used a good tripod, solidly planted, mirror was locked-up, & there was no breeze.

I think Tony, Julie, Jim and George hit the nail on the head. Wrong lens & wrong f/stop. The same shot with the 40-150mm kit lens at 150mm & f/10 produced a much sharper foreground.

What a great learning experience this has been! Thanks to all who responded.
