press-on lens shade for 203mm Ektar?

[paulbarden]

I'm sure someone here will have an answer: I'm looking to get one of those press-on Kodak "Series" adapters that will allow me to fit a lens shade on my 203mm f7.7 Ektar lens. If you have one of these lenses yourself, you know it doesn't have a threaded front mount, so a press-on adapter is required. I've seen conflicting information about exactly which one is correct, but most suggest its a Series VI, 33mm (1&5/16) adapter. Yes?
Can anyone tell me please, exactly which Series adapter I'm needing for this task? Thanks very much.

I don’t have that exact lens but several similar. You need series filter SLIP-ON adapter. You’ll also need a retaining ring or hood to retain the series filters. My profound suggestion is that you sent an email to Tim at FilterFind.com, tell him what you have and want… he’ll hook you up appropriately. Not only does he have a large stick of adapters and filters, but he’s a terrific human being, has good prices, and ships super fast. Series VI sounds about right to me.

Note: measure the OD with a ruler. Getting exact size is good but the SO adapters are adjustable plus/minus .5mm, or maybe even a bit more. If adjusting, use needle-nose pliers and adjust slow as too much bending can work harden the aluminum and tabs might break.

You can measure in inches the outside diameter of the lens and search on e-bay for a slip on series adapter for that size. I just recently did that. I then converted the adapter to use 67mm filters by gluing on a suitable adapter (step up ring) using JB Weld.

Thanks, I have found what I need!

Did that, found the right adapter at Blue Moon, and purchased it. Thanks!

The 203 Ektar takes a Series VI-33 mm press on adapter.

Thanks, Keith - that's exactly what I just bought.

BrianShaw, thanks for mentioning FilterFind. Looks to be a very useful resource. And paulbarden, enjoy your 203/7.7 Ektar. It's a fine lens and I should have kept mine.

Oh, I know! I've had it for several years, but I've never bothered to source a filter/shade adapter for it before now.

I purchased a 43mm to 67mm filter adapter to glue on my Series 6 ring.

[BrianShaw]

Well I guess I won’t write what I was going to write: the best part of Series VI is that there is a huge amount of filters still available, and not very expensive. More than any other series size it seems. :)

Brian, I have adapted all of my large format lenses to use 67mm filters. That way I have one set of multi-coated filters to carry. There definitely plenty of Series VI filters around

Paul,

I adapted a 52mm stepping ring to the series VI threads on my slip-on adapter for my Ektar 203mm lens. I had one machined, but you may be able to find a Series VI to 52mm adapter ring somewhere. Or, you can take an old filter ring (without glass) and file the male threads and glue it into the Series VI threads.

This has two advantages: 1. You have a lot more, readily available filters to choose from. Plus you may be able to use filters you already have with a 52mm stepping ring. 2. You don't need the retaining ring to hold in your filters, making mounting filters much less fiddly.

Best,

Doremus

You have it all worked out!

I should seriously think about following your lead. Over the years I’ve accumulated 49, 52, 67, as well as series V, VI, VII and VIII… and Bay60. I’ve yet to grab the wrong filters but there is plenty of opportunity for error!

Ugh! Why not just buy the right adapter? They are not hard to find. Glue!? You sound like Chauncey Walden!

That's good to know, thanks. What does one look for when searching for the correct filter size?

Series VI

Thanks. I didn't want to assume Kodak labeled these as simply "Series IV" size.

Just a note for anyone finding this thread in the future - in the UK (and presumably the EU also) a version of the 203mm marked 'Mount 370' is common (I think this was made in the UK). It takes a range of push-on accessories (filters, hoods), similarly marked as '370'.

A quick google for 'mount 370 ektar' and selecting 'images' should give you examples.

Thanks Brian, I have send him email to inquire about purchasing some filters.

[Chauncey Walden]

Now, now, Keith. I may have one slightly altered filter holder. Or maybe two.

Some of the later ones have a screw thread. Mine is from 1961 and I use a #27 series #VI screw on adapter.
