Calculating maya cam <-> canon eos 1

[Emil3d]

You need to match the Angle of View attribute in Maya to your real camera

Unfortunately with digital cameras, chances are small for exact calculation of the Angle of View equivalent in Maya.

Typing the focal length of your camera lenses in Maya (50 mm in your case) will be exact match, if you use a film camera and choose the type of film from the Film Gate pop up menu.

The problem is that you are using a digital camera and digital camera’s sensors are not equivalent to the size of a 35mm film or any other film standards. Manufactures are free to make the sensors at any size they like. Check this thread (http://forums.cgsociety.org/showthread.php?t=220651&highlight=camera) for additional details on this topic.

Your best bet is to recreate a shot from your real camera in Maya by interactively adjusting the camera controls to fit the perspective and then save the settings as a preset for future use with photos from the same camera. Make a shot of something large that clearly displays the perspective, for example: a street with buildings or large room with straight walls, and then in Maya just put a few planes to match the walls or the buildings.
