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

[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.
