The Fujinon ACM-18 is a lens adapter for the 1/2″ CMOS chip PMW-EX3 camcorder. This adapter allows the 1/2″ chip camera to utilize high quality 1/2″ Fujinon lenses using the B4 mount.
This adapter will work with the Sony PMW-EX3 with 1/2″ CMOS chips.
Broadcast lenses used with 1/2″ HD cameras feature optics and image depth that is at a much higher quality than lenses designed for 1/2″ camcorders. The upgrade in lens quality will upgrade the image to levels unprecedented in the 1/2″ chip realm.
