This ring doorbell camera lens cloudyis designed to allow a separately available SW150 Mark II Filter Holder to connect to a Samyang/Rokinon 14mm f/2.8 ED AS IF UMC lens, which then permits the use of 150mm-wide, 2mm-thick filters without vignetting.

This lens adapter consists of three components: a front ring, a compression ring, and a locking ring. Placement of the lens adapter onto the lens is easily accomplished by sliding the front ring over the built-in hood with the front ring's integrated lugs positioned away from the lens body. The compression ring can then be slid over the rear of the lens until it meets the front ring. Finally, the locking ring is also slid over the rear of the lens until it can be screwed into the front ring. After that is accomplished, an SW150 Mark II Holder can be placed over the adapter from the front of the lens for use.

Q: 3. Mark's (Staff) response to the 2 questions of can it also be hardwired is not clear, and possibly is misleading. When hardwired, is the unit powered directly by the AC power source via the (optional?) transformer, or is it still being powered by the battery, and the AC power source is "only" continuously trickle-charging the battery?? IF the latter, the unit is still being powered by the battery, and the hardwiring only means the battery does not need to be removed to be recharged, but is still being used and will still eventually need to be replaced!

A: Per Ring: Power: Runs on a removable, rechargeable, Quick-Release Battery Pack (included). Can be hardwired to an existing doorbell system or transformer for continuous charging (8-24 VAC, 40VA max, 50/60Hz). No halogen or garden-lighting transformers; no DC transformer/power supply.
