Kodak Series VI lens hood, thread size?

[peter k.]

I have a very nice set of series 6 filters for B&W.. on an Ektar 101mm lens, but no polarizer.
You can get them on E-bay, but there shot, so would like to maybe attach a polarizer to the lens hood thread size.
Anyone know the thread size or have a suggestion for a solution?

There is a solution: Buy a Leica or Leitz 13358 polarizer. It screws into the series VI holder in place of the retaining ring. The problem is you can't use a hood, so you will need to shield with your hand or hat. Beware that these polarizers are old and many show delamination, but keep watching the big auction site and a clean one will show up. I use the 13358 with a Bayonet II - Ser. VI holder as well as on a E39 - Ser VI adapter on a Leica M2.

This is as far as I can tell by holding a scale to one of my filters and a retainer. A series VI filter is about 1-5/8 inches (41.3 mm) in diameter and drops in. The thread on a series VI retainer ring is about 1-11/16" (42.9 mm) in diameter and maybe 32 threads per inch (0.8 mm pitch).

Yes, true, and the series 6 pol are also available, but... as you stated many show wear, so trying to find another way, other than just holding a polarizer in front of the lens.

Can't you screw in a 43mm stepup ring partway and put a pola on there?

Have no idea... are you stating that the thread hood is 43mm.. that's what I'm trying to find out.
If so, then that might work, and would be able to use the B&W filters with a Pol when shooting B&W, or be able to just put on the pol, .. on the lens hood for color.

how about buying a typical threaded polarizer of appropriate size and carefully cutting off the metal band. maybe run some gaffers tape around the glass edge. now you have a modern Series VI polarizer.

This is a can of worms -- the Series filter retainer threads are sized in inches and the thread pitch is 32 tpi. That works out that nothing from the metric standards fits reliably -- but in some cases you might sneak by! Purportedly a Series VIII is remarkably close to 67mm. But the retainer thread for Series Vi appears to be 1 3/4" or about 44.5mm. Ideally one might find an adapter to fit the lens directly that takes standard screw-in filters and use those all the way. There are still a fair number of adapters around (ePrey, etc.) in the push-on style, it's much less likely to find adapters that can screw into a particular lens. (I have a Series V that fits my Argus C-3!)

Ah -- but rotating it to observe effect could be a bit tedious!

OK then buy a 77MM and hold it in your hand!

The lens side thread is close to 43/44mm, so it might just about fit.

Thank you for your replies.. and thus it seemed we needed to do a creative work around.
I have on hand a 52mm Pol for my Nikon 35mm, so went and tried it on/in the lens hood. To loose, but close.
So took a black wire tie, and cut the trail and head off. Heated it up and formed it into a smaller circle than 52 mm
Placed it on the threaded end of the 52mm Pol, and then used red duck tape cut to about a 1.4" to hold it place, for a couple of turns, and now can friction place it into the hood, with the capability to adjust it, and remove it.
Because its a 101mm Ektar, with Hood attached to a 1 1/4" to 315mm adapter, the 52mm Pol on the Hood, is wide enough and is not interfering as far as I could tell with the image on the ground glass.

As for adjustment, one can adjust it with the ground glass, or as I have done in the past, when hand holding the Pol, adjust to the scene, and then carefully hold in front of lens. Now I can just insert the Pol into the Hood, focus and take the shot. Not having to have the camera on a tripod, as we did in the past, as did not have enough hands to do it all, giving me more freedom and flexibility. Yahoooo...

The only time I may get in trouble with the Pol being about 1/2" from the surface of the lens, may be when I would do close ups. But then most likely would not need or want a Polarizer on.
Now we need to purchase another 52mm for the 35mm as this one has been confiscated and stolen by the bigger boy, .. MF.
