Lens Comparison Table

For FLEX:V100R2 and V120:SLIM Cameras

(See the archived V100 and FLEX:C120 version of this table.)

Aren't sure what Field of View (FOV) you need for your motion capture application? See the FOV Calculator below to determine which lens will best meet your needs.

See the FLEX:V100R2 Lens Changing Tutorial video to learn how to swap out lenses.

*  This unfiltered lens is the stock FLEX:V100R2 lens.

^  Lens is compatible with V120:SLIM when using either the standard lens holder M12 OR the V120:SLIM Case and CS to M12 lens adapter.

Notes:

1. The FOV listed in the table above is horizontal FOV in degrees.
   
2. When using lenses which yield a field of view greater than 46° with the FLEX:V100R2 camera, there will be poor IR illumination coverage because the IR illumination is designed for a 46° FOV.
