I just recently got back into instant film by shooting Fuji FP-100B and FP-100C pack film in a Polaroid pack film holder for my medium-format Mamiya 645 Pro. Unfortunately, although the images are beautifully sharp thanks to the good optics, the image is only the size of a 6 cm x 4.5 cm negative. Now I'm starting to look around for a camera that will take the same Fuji pack film but will render an image at full or near-full size. The Film Photography Podcast has been advocating the Polaroid Colorpack series of cameras, but their images don't look too great, like the Colorpack cameras have cheap plastic lenses instead of glass. Can anyone recommend to me a camera that will take high-quality, sharp and large size images with this pack film? Thanks in advance for any info you guys could provide.
