The Fujinon ACM-10B is a lens adapter for 1" C-Mount cameras. This adapter allows the 1" C-Mount cameras to utilize high quality 2/3" Fujinon lenses using the B-Mount.
This adapter will work with JVC HDV camcorders such as the GY-HD100/101/110/20/201/250/251.
Broadcast lenses used with 2/3" HD cameras feature optics and image depth that is at a much higher quality than lenses designed for 1/3" camcorders. The upgrade in lens quality will upgrade the image to levels unprecedented in the 1/3" chip realm.
