Thanks, but...
This was just a gift borne out of my impatience with my husband. We went to the Getty Center to see an exhibition of Edward Weston's Photography. Go see it if you have a chance - and if you do let me know so I can take off work and join you!
Anyway, he (my husband) was taking forever to frame a shot in the gardens and I was waiting when I saw the hummingbird fly into the tree, land on the branch and then he posed for me. He stayed for several minutes. The sun was setting and the tree was in a garden area where I couldn't get any closer to zoom with my feet. I had taken the 24-105 4.0 on my 5d and I already was standing in mud (in dress shoes no less). Most of the shots he silhouetted because I was shooting into the sun. So this, even though I cropped in, was a gift. Oh, and my husband ended up waiting for me.
A few years ago, when I was new to digital, I went to a friends home to shoot the many hummingbirds that visited her every day. No matter what I did, I couldn't get any photos of them. Then I went and spent a weekend and tried again. No images worth anything. They are really hard to photograph - unless you have really long glass and a fast shutter and some flash to freeze the motion.
