Things have changed. I had to get another camera body before the last trip because the old 20D was having some depth of field issues on macro shots and it was not going to be acceptable to have anything out of focus. It can be corrected, but why should I have to take a picture twice? I appreciate the discussion. From my experience I am now going to get a small pocket (cargo pants pocket) camera to take along while I am out stalking around. I'll have to seriously review your suggestions. The "big white gun" Canon 6D, L70-210 2.8 IS USM with 2x Doubler is the current big gun and is in the pack and it gets taken almost everywhere. It is the tool for camera hunting. All I can afford. I'd love to get an 800mm but, that will have to wait for a long time. It would be nice on those stalks where you just run into something cool to be able to take a picture on the run. Currently the iPhones job. Not the best but it works in a pinch.
