Canon Eos lens and any Medium Format Digital back like ALPA TC/FPS concepts
compact ALPA TC style camera for Canon EOS lens / Hasselblad V mounts.
Original based in FOTOMAN D-mini.
Canon EOS lens mounts has lens eject button for safety mounting.
I designed front parts via 3d modeling software and making mockup from 3d printer ,
Finally Full Alloy CNC machining and Black matte finished. Done.
Including ingenious Reverse design copal 3 mechanical shutter
B, 1 ~ 1/125 sec available
Mod to Sony Mirrorless FE mounts.
Due to enough flange back distance and very large image circle, I always wanted to buy this lens and finally I got it.
To modify my Sony A7 camera, I come and go machinist studio several times.
focusing in 1m ~ infinity, Helicoid type. Good sharpness center.
but Weight is so heavy… Very difficult for Handheld shot and due to larger diameter, not easy hand grip.
Sinar P2 mod _ world's 1st AF technical camera
sinar P2 mod for Sony mirrorless project
Small size lens board 100mm x 100mm.
Unlike my older modifications, It was designed for Sony 2nd, 3rd body.
It has electronic AF, aperture control board so It can control focusing, aperture via rear Sony Mirrorless body.
It enables Tilt/shift with Auto Focusing !

GX680 modify for Sony a7 series
Before digital Photography was born, Fuji GX680 was introduced. Well made, a very nice technical camera.
because of Image size (6x8cm), It is comparable larger film and lighter than 4"x5" cameras.
but Now, very fast digital generation. Many people dumped their GX680 body despite the very high price and good camera.
I want breathe new life to old GX680 body within first mirror less, Sony a7 body.
Sony a7 has very short flange back so It can accepts Most lens. so I designed for shortest flange DSLR, Canon EOS.
X/Y Geared shift for Sony a7 series
Canon EOS EF lens mounts,(or Nikkor G adapter with aperture control? )
so virtually all major brand lens accepts because of shortest flange back DSLR.
X/Y axis GEARED shift mechanism. zero point locking system.
Genuine Schneider parts.
shift range : X/Y both +/- 5.5mm (total 11mm)
It has safety lens locking system unlike my earlier designing cameras.
similar to Hcam TS master (I like it !) but My design Can not tilt.
Most parts are disassembled fro Original Hasselblad Parts.
Most part are disassembled from Original Hasselblad parts.
like H system CF adapter. It can operate Hasselblad CF line lenses by Carl Zeiss.
Shutter open for take the compositon and focusing.
Lever windup, Shutter closed and cocking to Shot.
for Hasselblad H mount (Hasselblad H3d, H4d, H5d, Phase one H, Leaf etc..)
However It can easy swappable Contax645, Mamiya AFD, Hasselblad V mounts.
It can add more technical features like Swing, Tilting, Shift…
but I didn't.
because I want to do NOT cutting original genuine parts.
GX680 MOD
GX680 is Very nice Medium format Technical Camera but Film Generation is Gone.
so We can buy very reasonable price.
so I designed it.
front : GX680
Rear : 3shot stitching and Tiltable, Hasselblad H mounts (Revolving)
It enables rear revolving system.
Taken order from German Architecture Photographer.
We're interested in new canon TS lenses.
It use prontor 3 professional shutter (no cocking), B, T, 1 ~ 1/125sec
canon EF mounts, and revolving system. for his contax 645 mounts.
