I put the older Sigma 70-300 macro lens on my Nikon D700, and wandered around downtown Ogden, Utah. They were having a street fair and farmers' market, so there were plenty of subjects. I like the selective focus. View in larger size on black background. (Baskets and Boxes of fruit, for Sunday Challenge) Image processed with GIMP. See: swansonphotos.com/ogden/index.html

This was actually a "lens test" I did while wandering around our campground at Denali National Park, Alaska. I was testing the macro capability of the Sigma lens I was using on the Nikon D700 camera. In this case, I closed down to F16, and got more good flower detail. But even with some detail, there is a bit of nice bokeh here. Image processed with GIMP.

Taken during a side trip near Wasila, Alaska. I was using an older Sigma 70-300 macro lens with the Nikon D700. Worked fine. Image processed with GIMP.
