    35mm film becomes medium format as soon as you load it into that fantastic camera.

    Any help would be appreciated.

    Hi Norman. I use a fantastic downloadable program called 'DOF Master' as well as a ground glass screen and loupe. The rest is testing the theory by shooting some film and checking the actual sharpness on a lightbox Actually by using a shorter focal length lens the DOF becomes greater.

    That looks really good. Love the camera store, how fitting!

    Fantastic, I love seeing projects like this.

    For nomenclature I would follow the this line of thinking:

    1) The Minolta 16QT is a QUARTER FRAME camera (image size roughly 1/4th that of standard 35mm frame
    2) Olympus PenF is a HALF FRAME frame camera
    3) I would call yours a DOUBLE FRAME camera

    If you were to make these...I would surely get one for Chrismuka!

    Hi Razzledog, yes depth of field is greater with short focal length lenses but the depth of focus (lens to film) is much more critical. Using a 15mm lens the difference between infinity focus and 1metre is a fraction of a millimetre. Norman

    No intention to downgrade the significant expertise behind this.....I have been eyeing and thinking about your constructions with lust, but scant funds. Very interesting to know a 40mm PE will cover 72mm and screw into a copal: will store away in memory banks (dont ask me for what though)

    Dammit Razzledog - now you've got me designing in my head. You've ruined my sleep for the next week. I might actually build something. My wife will be furious!! You see, I've got another 2D in the garage ...

    BTW, that's a really cool idea you had and the workmanship appears to be excellent. Keep it up.
