Sensor Swab Type Explanation

July 30, 2013

While looking for a description of the differences in the three types of sensor swab products from Photographic Solutions I came across this reference.

The overall rule seem to be that the key is:

  • Type 1 – For reduced frame (crop 1.3) sensors
  • Type 2 – For reduced frame (crop >1.3) sensors
  • Type 3 – For full-frame (35mm) sensors

There are discrepancies though (e.g. the Nikon D7000 being mapped to type 1).

On a related note Thom Hogan has a nice article on sensor cleaning.

cpufreq-set -c 1 --freq 2000MHz

Read out current frequency by doing
cat /proc/cpuinfo
