Hi Jeff,
Love the shot. Very colorful.
What do you think is causing all the little circles in the background?

Bob, I think it is because it is a Sigma lens and not a Nikon There is a big difference in price, Jeff

Well, it's still a very nice picture.
I have not seen that effect in other pictures you've posted, so I thought I would ask.
I still like the Sigma 400 zoom lense you have. I'm thinking of getting one myself.

Another shot through a double window glass of a bird in the back yard taken with my Sigma 135-400mm APO lens and Nikon D90.

These are actually much sharper in the original than they show up here. I still haven't been able to get sharp pictures after resizing so they can be posted here, Jeff

The blue bird seems to come out of the magazine, what tactic did you use? The green background made it seem to be super embossed.
