Trutta Posted April 23 Share #1 Posted April 23 Advertisement (gone after registration) I was curious to see if anyone knows how to read the scale on this filter, the ring spins and is marked 0 to 17. Is there any references out there for this filter? Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Carlos cruz Posted April 23 Share #2 Posted April 23 (edited) Fairly easy you’d first observe polarity with your eye check the number on top, put the filter ob the lens and apply same number. you can check if the numbers refer to polarity factor. But usually it depends on your position relative to the sun, subject of your pic etc., so usually the numbers are only there to give you point of reference Edited April 23 by Carlos cruz Quote Link to post Share on other sites More sharing options...

Trutta Posted April 23 Author Share #6 Posted April 23 (edited) You are correct on the camera/lens but definitely not a swing out filter. Edited April 23 by Trutta Quote Link to post Share on other sites More sharing options...
Carlos cruz Posted April 23 Share #7 Posted April 23 Advertisement (gone after registration) Never suggested it’s a swing out filter. The font used on it clearly shows older provenance. I only described how you’re supposed to use it. Later swing out version made your life a bit easier. But with metered camera you can guess the polarity just by observing the light meter when turning filter Quote Link to post Share on other sites More sharing options...

But with metered camera you can guess the polarity just by observing the light meter when turning filter It's just the 'official' version of buying a normal PL filter and putting some marks around the edge, colour dots or scratches, so you can pre visualise the PL effect by eye then translate it when the filter is on the lens. Nice to have though. Quote Link to post Share on other sites More sharing options...

A filter declared for Summicron 5 cm onto a Summicron 40? Front Thread does not match and I see no evidence of some adapter (unless the back chrome ring is a step down adapter... 40,5 to 39..dunno if such a device was made) Also, the black barrel looks to me not the one of 40 f2 (I haven't it, though). The focus knob Is like in 40 f2.. But I think that during the long life of 50 f2 maybe it was used on it.
