[Question] I'd like to know the details about an optional external viewfinder. Is there any information about the GV-1?


The GV-1 is the viewfinder specially for the GR DIGITAL II / GR DIGITAL, that is for checking composition in 28/21mm.

Main Specifications:

Lens name 28mm/21mm external viewfinder (value for 35 mm cameras)
Lens type Alberta type inverse-Galileo lens
Optical view finder (with 5 lenses)
Finder magnification 0.42

Dioptric Finder image - 1.0D (3m)
Eye point From the final face of the eye point lens: 15 mm

For mounting instructions, please consult the GV-1 User's manual that come with the GV-1.
For cautions, or care of the camera, please consult the GV-1 User's manual and the camera user guide.

[Using with the GH-1 (hood & adapter) or with the GW-1 (wide conversion lens) ]
You may see vignetting below through the viewfinder, it will not affect a captured image.

[Note]
    • You cannot use the external viewfinder with an external flash at one time.
    • Please use framing with it only as a guide. Since a framing with the optional viewfinder will be taken an image with a little larger range in the left, upper, and bottom side.
