I've discovered the bargain of the century, Jessops are doing a lanc contooler for £30. I've been wanting to buy one of these for ages but couldn't stretch to the Manfrotto one. My am cam doesn't have a focus ring, which I find really annoying (it has a toggle switch but I get camera shake, especially at the far end of the zoom when MF is more critical) but the Lanc contoller does. As far as I was told in the shop it was only suitable for Sonys or Canons, dont know why this is, but its a sony I use of my am cam and it works a treat. the guy in the shop demoed it on a flashy canon one and it seemed to do the trick. Its got a zoom and rec start stop and straps onto my tripod handle.
