Comments about Arca Swiss ARCA-SWISS Monoball Z1 DP Double Pan with Classic Quick Set Device, Supports 122 lbs.:

An excellent ballhead! Versatile! Handles heavy loads with ease. The double pan feature enables you to position a wide variety of setups. Excellent for panoramas. All the controls and the classic clamp for the quick release plate are easy to operate in cold weather with gloves on. A wide variety of quick release plates are available from Acra Swiss and other sources. The friction clamp for the ball head is very smooth in all temperature conditions. The friction clamp variable tension adjustment enables you to set the perfect tension for any camera lens combination you are using. You can precisely position your camera on the first try. This ballhead provides a very stable platform. I've gotten clear images with a 2400mm mirror lens. Rock solid with 400mm and 500mm lenses.
