Title: Add-on lens?
Post by: acellier on April 24, 2012, 02:01:46 PM: Has anyone any experience with adding (teleconverter) lenses onto these cameras to reduce the angular field of view?
I'm interested in being able to read license plates.

JavaLawyer, did you ever get a chance to try that lens?

We moved recently (living out of boxes!), and I'm still searching for where that lens is packed ???
I'm also very eager to test this out. . . if I ever find the lens.

The wide angle lens definitely increased the camera field of view by perhaps 10-15 degrees on the left and right sides of the frame, but given the camera's vantage point, the increased field of view didn't really add any significant value. I'm curious how a teleconverter would work.

The lens came with an adheisive ring that sticks to the frame around the circumference of the DCS-932L lens. The magnetic lens, in turn, is attracted to the ring.
