videoVIP 0 Posted August 2, 2011 Just a WAG: An adaptor (focal length) of some sort...? Share this post Link to post Share on other sites
Birdman Adam 0 Posted August 3, 2011 Could you maybe take the pictures a bit farther away, and zoom in to compensate. It would be better if we could see it in focus. Looks to me like they are cheaping out by offering bigger lenses with an adapter that limits light. Share this post Link to post Share on other sites
Soundy 1 Posted August 3, 2011 Looks to me link some kind of filter, but would be hard to say exactly what it does from a photograph... cut filter of some sort? Polarizer, maybe, to kill reflections? Share this post Link to post Share on other sites
rory 0 Posted August 3, 2011 you can buy the lenses with the option of an ND filter, so perhaps that is it. Share this post Link to post Share on other sites
mike_va 0 Posted August 4, 2011 Possibly ND, but wondering why they did that as they also had the sense up set at 8x on a 1/2" B&W...works fine at night without it at 1x... I'll try this weekend to see if it affects the viewing angle. Not a cheap lens though but a little older C mount Tamron IR corrected 1/2" varifocal autoiris.
