TELEPHOTOGRAPHY
with SLR & D-SLR cameras OPTICRON SCOPES
Overview
Telephotography (taking high magnification photographs)
is now easier than ever to enjoy using Opticron
telescopes in conjunction with SLR & D-SLR cameras. In
this system the camera lens is substituted for the
telescope and coupled directly to the SLR camera body
using either a telephoto adapter or an
eyepiece+photoadapter combination.
T
mounts, available for nearly all makes of SLR
cameras are needed to connect the assembly to the camera
body. It should be noted that while it is
possible
to take perfectly acceptable high magnification
photographs of wildlife in a wide range of environments
using a telescope as a telephoto lens, the relatively
small apertures, fields of view and depth of focus put
an upper limit on the quality of the final image and
one’s ability to successfully frame shots at close
range.
The chart below shows the current range of telephotoadapters and photoadapters available to enable you to convert your Opticron telescope into a long focal length telephoto lens.
Notes. Focusing is facilitated on the telescope. Camera may need to be operated in 'MANUAL' mode with shutter locks disengaged where necessary. The high magnification to aperture ratios result in slower shutter speeds compared with conventional telephoto lenses so ISO400+ settings are suggested when using D-SLRs. For 35mm SLRs 400/800 ASA film is recommended. If possible use a cable release or remote control to reduce camera shake when operating the shutter.

Initially there will be four different bayonet fittings for high quality
'scopes such as the MINOX MD62 range, Zeiss Diascopes, Leica Televids,
Swarovskis and Kowas. Being watertight and shock-proof the DCM can
comfortably be used in adverse weather conditions.
