Tks again Taha,
i wrote to omegabob2 as you sugested.
I’ve found the datasheet for the lens i own, Miniature Glass V-4301.9-2.0FT 1.9mm 1/4’’CCD . How do i know the diagonal of this? You’ve suggested a 25 26mm lens to have less distortion. Would it fit in a 12x0.5 CamerA?
Best Regards.
Sorry you misunderstood me, i talking about the diameter of the filter not the lens.. if you have a wide angle lens like i do (mine is 120degrees) and you have a small diameter BP filter you when you place the filter on top of the lens you get the barrel effect where you can see the internal edges of the filter. to minimse this you should get a larger filter (in diameter) so this doesnt happen
