That may change with the > *ist-D though.... well, i am mostly shooting small birds right now more or less because that's what is handy to try and haven't had much opportunity to shoot anything very large except with tame ones. last weekend was the first time i could really try to take some of red-winged black birds, but i had all of 45 minutes to spend doing it, so i didn't have a chance to sit for a while and let them get used me so i could move in closer. OTOH, i did see a male/female pair sitting next to each other, enough to identify in binoculars, but not enough to photograph. > I have a monopod that I almost never use - it is not heavy enough for the > A* 400.

But for long telephotos, the > gimble should be best. the nice thing about the Gitzo leveling base on the tripod is that it makes it easy to change heads, if you need to. you thread the head on moderately tight with just fingers and then there is a lever to turn the thread itself an extra quarter turn to lock down the head. the base fits only Gitzo Systematic tripods, so you would have to switch brands. i don't know of anyone else's addon to a tripod that does the same thing. the Wimberley locks down with some easy-to-turn large knobs and doesn't budge under normal loads. > I've never even seen the beast but 1200mm would be a whole order of > magnitude over anything I've used.

FWIW, Canon has a 1200/5.6L IS lens that weighs almost 37 lbs. the A* 1200/8 has two 3/8" and four 1/4" mounting holes in the base. from what i can see. you want to use at least 3 of the holes on a long Arca Swiss plate. i use the Arca Swiss plates on all of my bodies and long lenses. especially on the Wimberley, i can balance the lens so that it moves freely and remains in position when i let go. the plates let me slide the lens to position it on the balance point as i add or remove things like extenders and the flash.
