Geminos Lens Matcher

Geminos is a tool that matches the field of view of two different cameras by displaying the corresponding focal lengths. This is useful when working with mixed sensor sizes and much more accurate than calculation with a simple crop factor. The app will show you the matching horizontal and vertical focal lengths, so you can even operate with different aspect ratios. Geminos also displays a proportionally accurate graphical representation of the sensor sizes and the horizontal/vertical match.

We've included all commonly used professional camera formats (see list below), but in case you don’t find your camera in the database, you can easily create custom formats. Geminos supports the use of spherical, anamorphic 1.3x and anamorphic 2x lenses.
