    making compact EOS mount camera like ALPA TC

    I want to use compact camera with short flange back, for Canon EF mounts.

    This camera almost Done. Original body is from FOTOMAN, china.
    I designed front parts via 3d modeling software and making mockup from 3d printer.


    It includes copal 3 shutter, so B,1~1/125sec. and Canon Eos mounts with locking lever. and Hasselblad V mounts.
    Made by ALLOY CNC machining.

    It needs fine focus tuning Only.




    Frankly, I want to make my own design camera, not like use other camera brands (FOTOMAN).
    so Now, I'm new designing more compact and lightweight camera.
    Above camera will sell after finished, for Making money to my own camera CNC machining.

    Focusing infinity Tuned.

    Perfect focus in any lens. Visual Distance Estimation on Eye.

    It is suitable for Wide angle Shift lens, like 17, 24TS.

    Original body from Fotoman Dmini
    tested by Phase one P25+V, 48.9mm x 36.7mm

    Including ingenious Reverse design copal 3 mechanical shutter
    B, 1 ~ 1/125 sec available

    No vignetting in 22, 39Mpx back (49 mm x 37mm)
    Not tested Full size back(54mm x 40mm) yet, but I guess No vignetting even Full size

    It has Canon EOS lens mount.
    So Any DSLR lens use this camera via adapter
    like leica R, C/Y zeiss, Nikkor, Olympus OM, M42 etc

    My Olumpus 35mm shift lens can shift any X/Y directions to +/-10mm.

    It means 24mm shift lens equivalent to Medium format.

    1st field test shot.
    All shot by AF nikkor 18-35ED Handheld (F8, 1/15 ~ 1/4 sec, ISO50) shot
    Hasselblad CF-39MS back, developed by PHOCUS.

    Due to NOT correct digital back shutter speed set , Some shot remains Purple fringe and Centerfold issue.
    Of course, If set to digital back correct shutter speed , No Problems.

    No vignetting in set to 21-35mm, It means equivalent 15mm~24mm angle of view to 35mm full frame format.

    Very simple, Use Depth of Field preview button.

    Set F stop to you want. push DOF button, hold it and Eject EF lenses.
    then You can see your preset f stop.
    and If you attach your EF lens to EOS body or EF control adapter like metabones,
    Aperture will be wide open directly.

    I have used past 5 years and Never problems.

    We may use these camera to wide-angle. so Preset aperture is no problems to shot.
