Thanks to LJ for pointing this interesting little product that brings ENG style zooming to standard DSLR lenses. Most people might be familiar with these controls from consumer camcorders, but for some high end ENG video cameras, you can purchase various focal length lenses that come with built in zoom controls (as seen here).

Looks like it connects via USB to control some of the Canon functions like start / stop video recording, and zoom in/out to magnify the video. These are the same functions already found in those USB Follow Focus devices (as seen here on eBay). No word on pricing and availability yet. The finish of the product in the video looks like an early prototype. I can see benefits to having smooth zooms, but price will determine if it's a Go or No-Go. [Thanks LJ]
