TheGodParticle/Hari Posted March 25, 2015 Share #1 Posted March 25, 2015 Advertisement (gone after registration) Hello all, Could you please help me understand what the numbers are for on this filter? I bought it for my lenses with 39mm filter size but do not know what the numbers signify Many Thanks, Hari Quote Link to post Share on other sites More sharing options...

gyoung Posted March 25, 2015 Share #2 Posted March 25, 2015 It should be a polarising filter, and rotates in the mount, you look through it and turn it until you get the effect you want, then note the number which is at the top, then mount the filter on the lens and then rotate the front until the number you want is at he top, and then the film should see the same effect you saw looking through it. An early and rather cumbersome way of using a polarising filter on a rangefinder camera, I have had one for about 40 years, and used a couple of times at least Later superceded by the ones with a built in hood which swing out through 180 degrees in frnt of the viewfinder.

Gerry So far so good then. This is what I was hoping for. Thank you for the quick reply Gerry. Looks like the long years weighed in on the filter, now it's stuck and doesn't rotate. Atleast I know what I should be doing and will attempt to get it to rotate again. I'm currently using the universal polarizer you mention but it's quite cumbersome and I was hoping this little fella would be easier to use. Looks like the UniPol, though bulky, is still easier to use 2 Quote Link to post Share on other sites More sharing options...

Orient XI Posted April 18, 2015 Share #6 Posted April 18, 2015 You will find that if you set the sun's time (i.e. ignore the "summer" or "daylight" factor) to the top of the ring it will be a good approximation to the position of maximum extinction.

muser Posted April 29, 2015 Share #7 Posted April 29, 2015 Advertisement (gone after registration) Take two of these numbered polarizing filter. The first polarization filter in front of your eye is for setting the number of the desired effect. This number is transmitted to the second polarization filter, which remains threaded in front of the lens. Quote Link to post Share on other sites More sharing options...
gyoung Posted April 29, 2015 Share #8 Posted April 29, 2015 See my reply of 25 March above, can't see why you need 2 of them unless you are taking a whole long series with it. Gerry Quote Link to post Share on other sites More sharing options...
Guest Posted April 30, 2015 Share #9 Posted April 30, 2015 See my reply of 25 March above, can't see why you need 2 of them unless you are taking a whole long series with it. Gerry Of course a single numbered polarizing filter is sufficient if one is willing to take the filter on and off the lens every time one wants to adjust the lens to the desired efficiency. But with two numbered polarizing filters it is easier and faster. As this idea is not mine, please have a look at the pictures and the video. https://www.youtube.com/watch?v=ypGjFHF-6kc Welcome, dear visitor!
