The heart of the Fuji GX680 system is an impressive perspective control camera body and a large lens lineup for it. Modern lens design techniques, coupled with special optical glass and Fuji's exclusive Electron Beam Multicoating (EBC) means impeccable performance and superb quality.
Specifications of lens movements on the GX680III camera body are: rise and fall is 15mm/13mm; tilt is 12 degrees up and 12 degrees down; swing is 12 degrees left and 12 degrees right, and Shift 7.5mm left and 7.5mm right. Most GX680 lenses will handle one complete movement on the 6x8cm format, but some will vignette when two or more movements are combined.
