Well, I got the Nikkor 70-300mm f/4-5.6G today in the mail, and I have to say, it is a very nice lens. As stated in another thread, I underestimated the long focal distance with camera shake. So, I was thinking about going to the zoo this upcoming spring. I was wondering whether people just make sure they go on a very bright day, are pretty good at holding the camera still, or you carry around a tripod/monopod. Maybe this should have its own thread, but I also have another related question. Tripod or monopod first? I dont do alot of stage photography, where people pose and give me time to set up a tripod, most of the time I am on the move with my D90. So, I was wondering if anyone thinks that it would be beneficial to get a good monopod first, then worry about the tripod later because of this. Ive never had experience with a monopod, so I didnt know if they had swivel heads like most tripods, if they had bubble levelers, or if they make tripods where the three legs fold up and you extend the middle to make like a make-shift monopod? I think I have seen these somewhere, but I can not recall where. Thanks so much in advance.
