Burzynski Ball Head II Mini Preview (field test to come)
Oh, I forgot to mention: my Burzynski Ball Head II got here, and it is a beauty.
I had to tune it a little by loosening the two tightening knobs, and then loosening the two side-screws, getting everything even, and then re-tightening, because it had a funny diagonal tight axis, but now it is just perfect. When I tighten the one tightening knob a bit, it can still tilt forward and backward, but stays tight sideways. It cannot pan though, except completely loose. This could be fixed with an RRS PCL-1 panning clamp, provided that the tightening knob wouldn't bump into the camera's bottom. See my question to Jack above.
The head is dead-simple. It consists, as far as I can tell without actually taking it apart, of two half clamshells, two vinyl bushings, two screws, two tightening knobs with rubber o-rings, and a reversible 1/4" / 3/8" screw which screws into the ball. That is all. The bottom is 70mm across and fits directly into my GT3541XLS, after removing the center plate. I did lose my hook, but then I never used it yet. The head only tilts to about 45 degrees, and so it needs to be used with L-plates or cameras with square formats or rotatable backs, or just to be shot in landscape mode all the time.
The GT3541XLS with center plate+Manfrotto 405 weighs 1,914kg + 1,743kg = 3,657kg, whereas the Burzynski weighs only 1,030kg, for a total of 2,944kg with the tripod, a significant savings. The head is strong as a bull, as amply described by Lars. I can't imagine what would rock this thing, except perhaps a 20x24 camera tilted sideways. Nah, not even that
The only problem I have right now is that I am missing the hardware to use with my RRS stuff, so for now, I will have to screw it directly to my cameras, or use my 405. That is not really a problem, since my Chamonix is not here yet (and indeed, hasn't been ordered yet).
I think I will order the PCL-1, but am not completely decided yet if I need panning. It might be handy to have for panoramas with my Leica M or MF kits. Note that the head doesn't rotate in the tripod, and the tight axis is along the split, so really, you need to align the split with the direction you are shooting to get the most of this head. This means setting up your tripod carefully.
