Field of View Tables, APS-C, 24x36, 645D, 645, 6x7
Posted By: Ole, 03-14-2010, 06:38 PM

This table shows the horizontal Field of View for the most common focal lengths for the various sensor and film formats in the Pentax camera line-up.

As an example, a 24mm lens has a horizontal field of view of 53.1 degrees on an APS-C camera like the K-3, K-5, K-7, K-70 etc.

To get a similar Field of View on a 24x36 mm camera like the K-1 you'd need a 35mm lens (gives a 54.4 degrees FoV as per the table, close enough) whereas on a film 645 camera you'd need a 55mm lens (gives a 54.2 degrees FoV).
