Telephotography using SLR cameras (digital or film) and
compact system cameras. In this system the camera lens is
substituted for the tel telephotoadapter or telescope
+ ey photoadapter. To convert MM3 60 models
to a 700mm
1
/f.11.7 telephoto lens you will need a 40215
telephotoadapter. Alternatively connect a suitable push
fit photoadapter to your viewing eyepiece.

A T-mount is
required to connect the assembly to the camera body.
Notes. Focusing is facilitated on the fieldscope. 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 choose an IS0 setting of 400. For 35mm SLRs 400 ASA film is
recommended. If possible use a cable release or remote control to reduce camera shake when operating the shutter.

This is an approximate figure based on 35mm SLR cameras. DSLR/compact system cameras use different sized image sensors
compared to 35mm so an equivalent telephoto conversion figure must be calculated separately.

Digiscoping with digital compact cameras, camcorders and cell phones.
Shooting high magnification photos and video through your fieldscope is possible if you have
a suitable camera, camcorder or cell phone. To find out how suitable or not your device is for
digiscoping, position it up to the viewing eyepiece and see if an image appears on the screen.
You may have to position the unit a few mm away from the eye lens of the eyepiece and
increase the zoom to get a full frame image.
