Adaptor ring for Profi Filter-Holder System
Rollei Profi Filter-Holder Systems come already equipped with adaptor rings. The purpose of an adaptor ring is to enable you to use your current lens with the filter holders for rectangular filters.
With Profi Filter-Holder Sets for filter sizes 70 mm and 100 mm, standard adaptor rings are included with delivery.
Additional adaptor rings are also available as an option for the 70 mm Profi Filter-Holder System for filter threads on lenses from 40.5 mm.
Other adaptor rings
Suppose, for example, you have a lens with a 49 mm filter thread. You can then use the Profi Filter-Holder System for filters with a width of 70 mm. In order to be able to mount this holder system on your lens you need in addition the 49 to 58 mm adaptor ring. Your filter set now consists of three parts:
- 70 mm filter.
- Filter-holder system for 70 mm filters.
- Adaptor ring for your lens.
