The MF-23, the only instant film back that supports Fuji camera models, uses a free-floating fiber optic lens to transfer the image from the camera film plane to the Polaroid film plane without any degradation of the image. Because the fiber optic bundle is in complete contact with the Polaroid film, the image is transferred with absolute sharpness and fidelity. There is no light loss and no color shift.
Manufactured with the highest quality materials, the light seal mechanism is composed of stainless steel and beryllium copper. All other interface components are black anodized aluminum and stainless steel. NPC believes that this is the best way to insure as good an image as possible.
Important: To use the MF-23, you must remove the conventional film back that comes with the Fuji 690 GWIII or 690 GSWIII. However, as manufactured, the conventional film back of the Fuji 690 GWIII and 690 GSWIII is not removable. To work around this feature, customers who purchase the MF-23 are given the opportunity to send their camera to NPC where they convert the conventional back so that it is easily removable.
