I have spent recent years trying to downsize my photography equipment, to get more mobile in the field, and to carry less weight on my aging joints. But, my recent foray with Judge Bill Burgess, and the spectacular images he was able to achieve with a 500mm zoom lens, got my competitive juices flowing again. I am still looking for my 1,000 mm lens; but, in the meantime, I found my 150mm – 500mm zoom, and will mount it on a tripod, and get back out there. It hasn’t seen any action for many years; but, I am looking forward to using it again. I also realized why I have been trying to downsize my equipment. These things are heavy, and my joints hurt. 500mmzoom
