When used in conjunction with a Borg telescope and large focuser, the combination enables full use of the medium format frame, unconstrained by the camera interface's width (see sample photo taken with a Borg 125 F4 scope). Shown at right are the Mitsuboshi camera and Pentax 67. Note that the Mitsuboshi camera allows for full coverage of the 6x9 frame while the Pentax 67 opening may cause vignetting even on the 6x7 frames with some optical configurations.
