tcook1 0 Posted June 29, 2009 I am wanting to buy a Dusk or Twilight style Neutral density filter to place over the lens of a CCTV camera for focusing. I do not want to use a Welder's glass. Could you recommend an ND filter in f - stops that would represent this type of filter for this purpose? Share this post Link to post Share on other sites

Why not, it's a heck of a lot cheaper than an ND filter and works just as well. Share this post Link to post Share on other sites
rory 0 Posted June 29, 2009 Day/Night or IR lens does not require filter. otherwise just focus in low light then no need for filter. Share this post Link to post Share on other sites
