This filter holder from Borg makes changing filters a simple and painless task. The use of a shutter cable (not included) pops the filter in its holder out in your hand without requiring the camera to be removed or anything to be unscrewed. Features include:
- Filter holders accomodate 52mm camera filters. A 48mm step ring is included with each holder. Additional filter holders to facilitate quick filter swaps are available separately (see part no. 7518).
- Filter box assembly accomodates an additional 52 or 48mm filter for stacked use (e.g. RGB filters with an LPS filter).
- Backfocus requirement: 15mm
- Shutter cable ejection mechanism
- Combo male/female M57 interfaces on both front and back ends allow easy attachment to most scopes and cameras when used with other Borg adapters.
