Jackie, I just took off some on sides for proportion-the 5D has more megapixels than the 40D and you get a better image when cropped,at least that is how I feel.
Jackie, In Florida you can get pretty close-This was taken at Anhinga Trail the night I met Oscar and Alberto and some of the birds were flying right next to us! It was fun and good practice.
Denise, all I can say is WOW!. The backround is beautiful and as stated above, the rim light and that inceredible eye make this a real winner. Excellent image.
