Asnow: these seem well exposed and maintain the textures and characteristics of the museum. I like the black and white treatments, although you might find using a little more "black" or shadow might help with the contrast. Thanks for sharing these. Do you have any photos from inside? I have that lens as well, but don't like it as much as my 17-55 E-FS f2.8 lens. Less reach but a much faster and wider lens.
