Quick Start Guide

We recommend using a Cold Mirror
filter when shooting with ‘normal’
lenses i.e. without special ‘IR-corrected’
or ‘Day & Night’ lenses. Cold Mirror
filters completely block visible light and
only allow IR into the camera. You can
also use an IR illuminator for night
vision in the dark. You can set up your
own custom picture profiles to get
exactly the look you want. Certain
lenses may not be able to focus to
infinity in infrared. For more
information check out this helpful page.
Pro Tip: Ribcage RX0 Cold Mirror
infrared filters are available in our online shop.
CROP FACTORS
While the RX0 does have a 1” 21MP image sensor an effective area of 15.3MP is used.
Here are the crop factors you can expect when mounting these common lens types:
2/3” C-Mount – 0.78x (some longer 16mm+ 2/3” lenses will cover the sensor
though they are technically too small)
16mm (Bolex) – 0.9x (most 16mm lenses will cover the sensor with no
vignette)
Super 16 – 1.03x
1” C-Mount – 1.13x
1.1” C-Mount – 1.25x
Micro Four Thirds – 1.45x
APS-C – 1.89x
DX – 2.01x
APS-H – 2.45x
35mm (Full Frame) – 3.07x
