Anyone with an HV30 knows that the focus wheel sucks, its impossable to shift focus smoothly. Thankfully, some guy at hv20.com built a ring that you attach to the front of your camera that lets you focus like you would a prosumer cam or dslr.
Its a really good add on for anyone with a HV20/30/40, and its also just one guy doing it, not a company or anything so its good to support him.
Rings are $38 + shipping
