Canon EOS 20Da, Japan Only
Feb 14, 2005 at 07:14:58 GMT
Canon Japan has this morning sprung a surprise on everyone with the announcement (in Japan only so far) of the EOS 20Da. This specialized version of the EOS 20D appears to be identical except for the removal of the 'hot mirror', the filter in most digital cameras which removes the InfraRed part of the spectrum. This camera would be especially suited to astrophotography as well as InfraRed photography, in use as a 'normal camera' it would probably require an external IR cut filter on the lens. In addition the camera has a partially transmissive mirror which enables live focusing on the LCD monitor (this can only be done for short times and requires the mirror to be locked up).
