The Arca-Swiss D4 Geared Tripod Head is a ball head designed for Arca-Swiss cameras, featuring a geared mechanism for precise adjustments. It includes a quick-release system for easy mounting and dismounting of the camera. Perfect for photographers looking for precise control over their camera positioning during shoots.
The Arca Swiss B2 Monoball is truly a MONSTER! I use a very heavy 4x5 setup with a scanning back for high magnification macro and micro work. I have tried many tripod heads over the years and just recently I was able to get my hands on this beauty. It is twice the size (or more!) of a B1 or a Z series Monoball, and it holds the camera at any angle absolutely rock solid, no creep, no shake, no movement at all. The exposures with a scanning back are not measured in seconds, rather in minutes, on top of that, high magnification macro is absurdly demanding when it comes to camera movement. So far, of all, the heads I have tried, this is by fay my favorite, I use it every day and will probably continue to do so for a long time.
