Rusan Eyepiece Reduction: Adjustment for Clamp Adapter without Bayonet

The Rusan eyepiece reduction allows for flexible use of optical attachment systems also as an eyepiece. This reduction is particularly suitable when a clamp adapter without a bayonet lock is used.

Simple Application for Maximum Flexibility

The Q-R clamp adapter remains firmly connected to the optical attachment system while the reduction is simply screwed onto the eyepiece. The eyepiece is then inserted into the clamp adapter and secured with the lever, ensuring it sits safely and stably.

Note on Bayonet Adapters

If a bayonet adapter is used, the Rusan Modular Adapter for the viewfinder is recommended.
