AVI,
The lense is only a 400mm. Camera gear is Canon. Mainly a 20D for this trip. while I had a 40D I didn’t like teh results is was giving me so stuck with the 20D mostly.
and Hurri, I did too much walking at times. I was even contemplating going home early that day the storm arrived. I was sweltering and had one of those head aches from being in the heat so often. But when that cool front came through and so quickly, I picked up and was fine for the rest of the day.
