I always assumed Maya cameras defaulted to 4-perf film.

According to Nikon's online documentation:

Horizontal Film Aperture and Vertical Film Aperture are the height and width of the camera's aperture or film back, measured in inches. The Camera Aperture attribute determines the relationship between the Focal Length attribute and the Angle of View attribute. The default values are 1.417 and 0.945.

I never bothered to convert 1.417 inches to mm until now.

It turns out to be 36 mm.

Maya has been defaulting to an SLR still camera -- or VistaVision -- all these years.

Matching a Vertical Nikon D200 to a Maya Lens

When you shoot using your camera in a vertical aspect ratio, you don't do anything special but turn your camera. To match Maya to your DSLR you need to make an extra little adjustment. When you swap the resolution X and Y, you have to swap the horizontal and vertical film aperture values as well...

It may seem obvious, but it's easy to forget.

Another solution is to leave the 'Film Aperture' values as if for a horizontal camera match, and change the lens from a 50 mm (lets say) to (it turns out to be) a 33.5 mm lens. But who wants to do the necessary work to figure that out?

A 'full frame' Nikon D700 has a chip size of 36 mm x 23.9 mm.

At 1.417" x 0.945" Maya's default camera back equates to 36 mm x 24 mm. So Maya default cameras equate directly to Nikon D700 lenses.

Thanks jfrancis, this is very useful.

You know, I always worked with a digital workflow, (from digital camera to digital delivery) and never bothered to check these details. It is good to know!
