mackguyver, thanks for the advice. My friend who influenced me back into photography via the Nikon D5100 DSLR is always commenting along the lines of "you can't expect to get a sharp shot unless you're 1/FL" (both of us have 300 2.8 IS but me a year and he just a month now). But now am going to use your technique provided my subjects cooperate, and fire more shots.
Now that I've played with my new old 1D2 a bit, I've come to realize how valuable the 6D auto ISO is, and oh, how did anyone live with that 1D2 LCD display! We're spoiled with these newer cameras and lenses.
Yes there are critters watching and that's why when I'm finally aching and exhausted from being immobile I typically tell myself, just 5 more minutes and ever so carefully start to move, looking everywhere. My beaver shooting, two years ago, proved to me how carefully he was watching me from up close, with me not knowing. Whoosh! Squirrels love to watch too.
Even funnier, I was leaving my spot in the bush and had to relieve myself (badly), so I'm standing there watering the the brush forever with the 300 X2 kind of over my back and looking around 200 degrees and there well within good shooting range is a very young fawn who bounded away just as I finished my business and started fumbling for the camera. Fortunately, he/she never reported me to the authorities.
