What’s It All About?
Large and heavy lenses such as theCanon 300mm f/2.8L IScan be awkward to use, even when tripod mounted. The preferred mount for most field photographers is a ball head, such as theArca Swiss B1pictured above. But, when a camera / lens combination like this is mounted on a ball head it can be unbalanced and easily tip forward or backward unless the ball is cinched tightly. This, naturally enough, makes panning when following a bird in flight or a wolf loping across a field problematic.
How it Works
The Sidekick places the lens and camera so that its center of gravity is directly over the center of the tripod. It also means that the lens ishanging overthis point rather thanbalanced onit. Consequently by setting the friction knobs to the desired points handling a large lens like this becomes almost a weightless experience. Following birds in flight, as I did at theSalton Seain January 2000 and atBosque del Apachein December 2001 was a breeze.
The Sidekick is designed to mount on an Arca Swiss type quick release plate. You’ll also need a ball head, such as the B1, with a rotating base and lock knob. (You have one of these already‚ right?). It’s also a good idea to get alongquick release plate. This will allow you to slide the plate forward and back so that the lens and camera balance perfectly. The photograph above shows how the plate that I use extends slightly to reach the point of optimum balance.
Of course you’ll also need a long lens with a rotating tripod mount collar. The Sidekick is designed for lenses in the 300mm‚ 500mm range. The company also makesThe Wimberley Headwhich is designed for larger and heavier lenses such as a 600mm f/4. It’s more expensive and larger than the Sidekick but if you’re the type of photographer that carries around a fast 600mm lens, neither of these issues will bother you.

A Word of Caution
As the instruction manual so rightly points out, you now have something like 7 lock knobs to pay attention to, between the ball head, the Sidekick and the lens collar. Murphy’s Law will always apply. The first day I used this set up, when I finished balancing the lens by sliding the plate I forgot to lock the knob. The weight of the lens and friction held it on while I was shooting but when I went to move the rig I almost dropped the whole lens and camera assembly into the sand. New gear requires new habits and a bit of extra attention to locking all knobs is required.
TheWimberley Sidekickis the product of a small father and son company. Its design is simple, it does exactly was it sets out to, and does it extremely well. The cost is U.S. $250 and it is available directly from the company, who are a pleasure to deal with.
