Terry_yang 0 Posted December 14, 2009 we designed and developed a new product with our new technology. It's called Sync-focus. Learn some information from the website below: http://www.forecam.com/english/cpfl_3.asp?id=106&flag=34 when using normal lens, we have two steps to make the image clear: zoom in or zoom out and then focus. The image is not clear while zoom in or out unless the next step focusing. But with our new technology, there is just one step: zoom in or zoom out. we make use of a samll stepping motor to ensure the focusing automatic when zooming. so it can always maintain clear object picture and make it convinient for remote control.
