Autofocus; Practical Tips And Tricks; Aligning The Reflector Sight To Cfinder Iii Using The Sensor Feedback - cmotion cfinder III User Manual

6.1.4. Autofocus

The autofocus function will seamlessly match distance measurement data from the cfinder III with
lens data from the camin to control the focus scale of the lens automatically.
If autofocus "on" is selected within the cfinder III menu, focus will be adjusted permanently until
turned off again.
Autofocus can be activated through a cvolution hand unit as well. Using a cvolution hand unit
various autofocus trigger options including toggle and mark are available. (For further information,
please refer to the latest cvolution user guide)
Note:
In order to use autofocus with a cvolution system, a lens file needs to be loaded in the camin,
a lens motor needs to be connected, engaged with the lens and assigned to focus. For further
information on how to create lens data, please refer to the cvolution user guide and the cworld user
guide.

6.2. Practical Tips and Tricks

Due to light conditions the laser spot of the alignment laser might not be visible in far distance. In
order to be independent of light conditions you can use the cfinder III sensor feedback to align the
reflector sight to cfinder III as well as to align cfinder III to the optical axis of the lens. cdistance (if
available) shows the same sensor feedback and can be used for these practical alignment methods
as well.

6.2.1. Aligning the reflector sight to cfinder III using the sensor feedback

1. mount the reflector sight to the NATO rail of cfinder III (Allen key, size 3 mm required)
2. mount cfinder III onto a camera tripod
3. remove the protective caps of the reflector sight
4. activate a target mark by turning the rotary switch of the reflector sight
5. aim at a fixed horizontal and vertical target as far away as possible but within the range
of cfinder III (e.g. aim the tip of a building against the sky)
6. pan the tripod head until the sensor does not get any feedback, measuring out of
range (e.g. hitting the sky)
7. pan back slightly until you have a first measurement from the target (e.g. vertical
edge of the building) and fix the pan axis of your tripod head
8. turn the pan adjustment wheel of the reflector sight (left/right) until the target mark
matches your target horizontally (e.g. vertical edge of the building) (flathead
screwdriver required)
9. tilt the tripod head until the sensor does not get any feedback, measuring out of
range (e.g. hitting the sky)
10. tilt back slightly until you have a first measurement from the target (e.g. horizontal
edge of the building) and fix the tilt axis of your tripod head
11. turn the tilt adjustment wheel of the reflector sight (left/right) until the target mark
matches your target vertically (e.g. horizontal edge of the building) (flathead
screwdriver required)
12. replace the protective caps of the reflector sight
