Indeed, many artists with no experience in photography will not be able to easily understand the relationships between focal length and sensor sizes / ratios. read more

Maya does not make it easier. What we know in the VFX/Film world as"sensor size" /"film back" /"film format", is known in Maya as"Camera Aperture". This attribute is found in any Maya camera's shape node. In the attribute editor under the Film Back section you will see: Film Gate, Camera Aperture, Film Aspect Ratio, and Lens Squeeze Ratio. read more

The focal length of a lens is the distance from the center of the lens to the film plane. The shorter the focal length, the closer the focal plane is to the back of the lens. Lenses are identified by their focal length. Focal length is expressed in millimeters or, on occasion, in inches (1 inch is approximately 25mm). read more
