Thought I'd take the old 1Dii for a workout before I forget how to use it. We spent Sabbath afternoon at the zoo with our friends. I gave the old 400mm f5.6L a workout that day-funny how spoiled I've become to having IS on my 70-200-had to shoot at ISO 1600 most of the day to compensate for my increasing as I get older Parkinsonian tremor. My arms and hands ain't as steady as they used to be. The kids shot with 70-200 f2.8L IS, the zebra and tiger with the 400 f5.6L, and the lizard with the 100mm f2.8Macro-no flash.
