How to fit Series 6 filters on Ektar 4.5, 152mm on Crown Graphic

[Ted Gross]

I'm trying to figure out how to use a Crown Graphic, early 50s vintage, that I purchased blind a couple years ago. Everything seems to be in working order. The camera came with several series 6 filters and a Kodak Series 6 adapter ring, 38 mm. I must be missing something, since the ring doesn't fit on my 152mm Ektar lens nor do the filters stay in place if I put them in the adapter ring that was in the carrying case.

Sorry to be dense about this- I'm sure it's been asked before- this is post #1 for me so hopefully future questions will be better. I see there are various
rings and adapters on eBay but I'm not sure what I should be looking for. I've read about filter systems that can be used with many different lenses, but I was hoping there would be a simple solution filtsince I already have 5 different series 6 filters.

You probably need 2 things: the correct size adapter, and the retaining ring or lens hood.

Thanks for the comments. Will bring the camera to a local camera store that has lots of misc older stuff, Biggs Camera in Charlotte. Will try to figure it out by trial and error.

Measure the outside of your lens. I think the 38 fit a 135 Optar. Son't know size of the 152 lens.

According to the 1953 Kodak Ektar Lenses catalog on the cameraeccentric web site, the 152mm takes Series VII filters using the 1-3/4" adapter ring. I may have a spare at home, I'll check this evening. But by all means try Biggs Camera, no guarantees on my end.

This site has an excellent article on series filters, rings, shades.

Very helpful article- now I can visualize what I need. Just strange that the adapter in the case with the camera fits a smaller Ektar lens than was on the camera. Probably had changed the lens at some point to the 152mm. The lot I purchased was on display in an antique mall- sort of surprised anything works, but the camera seems to be in good shape.

That is a really good article, Jac... thanks. I didn't really learn anything new but it is well written and accurate. I wish I had read that years ago when I figured out Series filters.

To the OP. If you buy online consider looking up an ebay seller named "Macintoshcat" or something similar. He is a good guy and is quite affordable; I've bought from him several times and he has great feedback. He also sells his adapters with the retaining ring. Some other sellers do not include the retaining ring and charge twice as much since you have to buy them separately. Suggest you pay attention tot he lens hood option for retaining the filter... it is well worth the extra expense.

Great advice on macintosh cat on eBay. He is selling me a Tiffen 45.5mm adapter for series 6, and will adjust it slightly to fit, since I really need 44.5mm. Thanks to you and the others who replied to help educate me on all this!
