Polarizing filter 13352 question

I bought a used Leica polarizing filter (13352) on ebay. It's my understanding that these work with E39 lenses, but I can't figure out how to attach it to my 35mm Summicron (newest version), which is an E39. It looks like there's no threading on the inside? Please explain to me what I'm doing wrong. Thanks!

It clamps on to the lens.

@signandsight,

if your lens has protection ring screwed on, try unscrew the ring then mount the 13352 outside, you can use the set screw to un/tighten the POL.

for me this hood +POL filter 13352 is A42 so clamp on type to be used with 42mm large front lens, and not E39.

I have the ring mount off; I'm taking the hood off to put this thing on. Is it just tightened and not threaded on like other filters?

Yes. Not all Leica filters are designed to be used with screw-threads.

Leica has, from earliest days, used a variety of clamp-on, bayonet mount or drop-in filters on many lenses.

Observe the 13352, you may unscrew the clamping device before mounting.

It's the one chrome thumb screw, just unscrew then put the filter above the lens at good orientation, "P" marking at noon, screw the chrome screw to fix it on the lens.

To use just swing the front part hood + pol up, turn the chrome ring to see the pol effect in your OVF, then push the hood back before taking the pic.

🤥

I think that you may better use the new form of POL filter, item 13356

OK, that's kind of what I thought you meant. Thank you for such specific help!

I have one of those. It really was made to fit earlier lenses. It does attach (clamps) to the current 35 Summicron. I rarely used that filter over the years, but the best way to use it is to put the thumbscrew at the bottom (6 o'clock position), swing the filter up, view and adjust the polarization directly trough the filter (not with the filter mounted to look through the viewfinder ), swing the filter back down, compose/focus and shoot. 

This filter will not mount on any lenses with a built-in hood, such as the current 50 Summicron, but fits nicely on a 'Rigid'.

For darkening skies or such, the 35 mm field of view is getting close to being too wide for a semblance of uniformity in the polarization. Remember : polarization is strongest at 90 degrees from a light source.

Enjoy your picture making with this filter.

clamping is not great when I mounted ( on screw-in thread/ protection ring off) on my Summarit-M 2.5/35 just to see if it works.

I think that I screwed the clamping well enough, but when I push to swing the filter+hood, it detached from the lens.

So beware to tighten the thumb screw to keep the POL well attached.
