Glossary | Spotting scopes | Special features
Spotting scopes may be equipped with additional functions.
Built-in digital camera
Some spotting scopes have an integrated digital camera for digiscoping. The advantage: especially compact, and no further camera equipment is required.
Some spotting scopes come with the (zoom) eyepiece included. Usually it is possible to tell from the spotting scope description whether an eyepiece is included.
A removable lens cap. Useful to avoid lateral reflections and condensation.
Rotating tube clamp
The spotting scope can be turned to the right or left for a comfortable viewing position.
May only be exposed to moderate moisture or light drops of water.
Threaded tripod connector
1/4" thread for mounting onto any standard photographic tripod.
Watertight optics are equipped with special seals and are gas-purged. This is usually with nitrogen or argon gas. Since these gases are heavier than air, they cannot escape.
Zoom eyepiece included
A zoom eyepiece offers variable magnification within the range indicated on the eyepiece.
