[Konvas] OCT-19 mount adapter on a Canon EOS 5D

[colcam at aim.com]

 This is where mirror box design splits into several distinct groups-- 

Large box and large mirror but smaller sensor

Large box and smaller mirror with smaller sensor

Small box and smaller mirror with smaller sensor

 
Large box and large mirror with large sensor


And on top of that "how much" of the sensor is used for the DV signal versus for still images, which creates new subcategories for each of the above. 

That's where the rub comes in.  You have to know not only the mirror box and mirror size and the sensor size, but how much of the sensor is used for what function at what time.

Well, at least the 7D works with the OCT19 lenses (has anyone tried the 
GH1 yet?). 
 

BTW: Not that it helps for OCT19 lenses, but I've heard that Canon will 
be releasing new firmware for the 5D to allow 24fps.
