Help with Kodak Series VII filter ring for 8.5 inch Commercial Ektar

[PunkFunkDunk]

I am looking at buying a Kodak Series VII filter ring for my Commercial Ektar 8.5 inch f/6.3 lens. Based on Kodak documentation I am aware I need the Series VII ring that is labelled as 1 1/3 inch (44.45mm) diameter.

However, I have come across examples of this particular ring on the auction site that come in one piece (looks like the piece that is pushed onto the front lens barrel) and two pieces (the aforementioned piece with an extra ring that looks like it is supposed to be screwed into the front of the adapter).

Is this second ring required to actually screw in filters? Also, does anyone know what the filter thread and pitch is that fits this particular Series VII ring? I am not interested in old Kodak filters and would like to pick one of these up in order to mount a modern filter, hence, need to first confirm what the diameter and thread pitch is.

Any informed info much appreciated as always.

The series filters are unthreaded.
The front ring is a retaining ring, necessary to keep the filter in place.
Check www.filterfind.net for more info.
Tim's site is a wealth of information, and he's a good source for Series, and other, filters and accessories.

Tim at www.filterfind.net has threaded filters in stock to fit Series VII holders.
They're under Series 7, listed as "54".

Umm, I think you mean 1-3/4" (44.5mm). That's what's written in my copies of Kodak documents.

Thank you both, the filter site is fantastic

I wish it went to bigger sizes

Yes. That is what I mean. Typo!

Thank you kindly. This answers my question. I will have to give it a miss since it doesn’t not provide the solution I was looking for in terms of screwing in a new brand name filter.

You could have SK Grimes make you a SWEEEET push-on adapter to use a threaded filter size of your choice.
Check their website out...

If you can get a Series VIII adapter to fit your lens you can screw 67mm filters into that.

And I believe that 49mm filters screw into the Series VII adapter ring.

Either option allows use of modern filters, if that’s what you need.

I did this and it is indeed very nice.
