I can only assume this camera has no auto focus?

It'll be of no use. Auto-focus lenses rely on the camera body to control the focus. For example, with the EOS adapter on Canon's XL camcorders, the auto focus is disabled even if you attach a Canon SLR lens.

Yes Barry, that was definitely a different experience playing with the JVC's focus assist feature. I started to feel like it was 'predator vision' hehe.

"It's just more an issue of what's been done in the past. Very few pro lenses in that style have ever had AF...I know I've never seen a single one, and I've been shooting for a while."

As a matter of fact fujinon have developed together with JVC professional lenses for HD broadcast. These lenses have an auto-focus option. They have been specially developed for the japanese market where HD transmissions are a fact. The reason being that HD focus is so critical that the operators could not always see on their viewfinders and monitors whether they were completely in focus. But when viewed on large HD screens one could clearly see that focus was a little off. The developers where thinking of sport registration. (the lenses where on view at the IBC in Amsterdam.) they are 2/3 inch EFP and ENG lenses. I have tried them and they are really amazing as they work different then tradional autofocus systems where the system will continually search for focus. The new system however was able to find focus and leave it at that. It could be used semi automatic so the operator can override autofocus when needed.
It is the final step........
