At long last the Arca Swiss Cube has arrived and we can throw away our ancient three-way heads that have been sitting on the studio tripod since Fox Talbot was a kitten. This device has been advertised on our window for months...with never a sniff of the real thing. Well, the real thing is here and it is wonderful.
Please note that I am not restricting the sales pitch to studio shooters; landscapists, architectural photographers, and panoramicists will also benefit from this piece of gear. It is simply the most precise way to orientate a still camera on the top of a tripod that I have seen.
I use a Gitzo tripod in the studio - it has either a Linhof pan and tilt mounting or a Gitzo 3-way head on the top, but neither of these alternatives come close to the Arca Swiss.
The Cube has precise rack control of two axes, and a positive lock mechanism for tilt. It has variable pressure for the knob controls, so that you can match the effort needed to move the camera with the weight of it. It has a precise panorama turntable at the top of the totem pole...so you can level everything before you spin around in the pano shot.
It is well-built. The Swiss are like that. Their cheese may have holes in it but their camera gear is pretty solid!
