CENTRALDS CDS-5D USER GUIDE
Characteristics of the modified camera
•
CDS-5D are modified versions of Canon’s general purpose DSLR cameras. Some
of original features of the Canon camera are removed and new features such as
TEC cooling and general purpose Drop-In filter holder are added for high quality
astrophotography. Followings are the differences made by the modification.
!
1.
The low pass filter attached to the
image sensor is removed and a MC
coated Hoya clear filter transmitting
visible light and infrared light is
mounted.
2.
Because the low pass filter is
removed, image blurring can occur
due to chromatic aberration on the
infrared lights recorded on the sensor
so the image sharpness can suffer.
This is more pronounced in the
images taken with refraction optics
than reflection optics.
3.
We recommend you use UV/IR cut
filter, light pollution filter and deep sky
filter at the same time while imaging.
4.
Y o u a r e a b l e t o d o i n f r a r e d
photography by mounting a visible
light blocking / infrared transmitting
filter such as a Hoya R72 filter.
5.
Various 2” imaging filters or 52mm
filters can be mounted in the Drop-In
filter holder.
6.
The lens mount does not have the communication point so the auto focus, lens information recording
and pulse signal transfer for ultrasonic motor operation which are based on the communication
between the camera body and the lens are disabled even when a Canon lens is used.
7.
You always have to focus lenses manually. Some lenses (200mm F1.8L) need power from the
body for manual focusing and you cannot focus these lenses even manually when they are mounted
on CDS-5D.
8.
Do not update canon’s 5D Mark III firmware to CDS-5D
. It’ll caused the hardware Errors.
9.
Camera was set to [Image Auto Rotation/OFF, ISO expansion/ON, Auto Power save/ OFF] and
other settings can’t be changed.
10.
CDS-5D is designed only for B-shutter mode and you can’t set shutter speed.
11.
If the USB or power cable is disconnected when camera control software is starting or closing, the
communication Error or Err1 may be occurred.
12.
When you meet these errors, please remove USB and power cable from camera. Then 3minutes
later connect USB cable and power cable.
