my bad, a typo. thanks for the correction.I agree with your 75% figure, but the pedant inside me feels the need to point out the pixel loss on each side is only 500, not 1500. The OEM G1 frame is 4000 x 3000, so you only need to trim away 1000 pixels total to make a square (3000 x 3000) image...
Also, provided you use "live view," two strips of gaffer's tape on the LCD works wonders as a framing aid for square-format compositions. If you position them carefully and get the resulting image perfectly centered, you can then automate the cropping-to-square process in PS by simply specifying the crop area as 3000 x 3000 pixels and the program will center the marching ants for you automatically.
Voila ... a digital pseudo-Hasselblad for cheap!
I once fitted a Pentax DA14 onto a Pentax MX film body to see what I could get. Square format due to vignetting, but nearly the exact FoV of my beloved old Hasselblad SWC. Unfortunately, not easy to work with as the DA14 lens was designed for on-body aperture controls.
