How do I get a filter on this thing?

[bvy]

Where do I find and how do I get a green filter (or any filter) on to a Caltar 375mm lens? The barrel diameter is about 85mm and it has no threads. I'm sure I can improvise something, but I'm not finding much information on how people might be doing this already. Thanks.

I have several older cameras and getting the correct fitting filters is a problem, for this situation Blu tac is a photographers best friend, never leave home without it

Check Lee filters

Waratten filters are thin enough to be used between the lens and film.

You can use a number of universal filter holders.
I use Haida filters and holders; they make a universal holder for both 100mm and 150mm filters, and their filters are of excellent quality.
Fully compatible with Lee filters as well, if you want to take a little from each.

A holder that fits on the rear element and gel filters. See AA's book The Camera. I have set of gel filters, for the most part I use high quality glass filters, does anyone still gel filters?

I use BluTack too.

But for a more permanent arrangement, you could consider getting a filter step-up ring with the correct thread for your desired filter set one side and the right diameter for the front of your lens the other, and bond it to the lens somehow - epoxy perhaps.

Obviously if you don't want to physically modify the lens (whether for aesthetic or potential resale reasons) this won't be a runner for you and a Lee or similar setup might be much better

You need to look at slip on adapters for Series filters.

You can use a filter holder on the back side of the lens or use a spring loaded clip on filter holder like this one. http://www.gmcamera.com/no-name-spring-loaded-filter-holder-unique.html

You need a series IX or X and a slip on adapter to fit your lens barrel.

scroll down to the chart of series filter sizes.

This has worked for me, only I use metal tape to attach to adapter ring so it will be easier to remove. But, at 85mm you may be beyond standard adapter sizes.

If you got even just one really good fitting lens cap, cut it out and glue an empty, double-threaded filtering to it.
For its original use as lens cap screw into that new holder a filter-ring filled with a plastic disc.

Still trying. I need something that goes on and comes off fast. The outside diameter of the lens barrel is 85mm -- no threads.

 

[removed account4]

you need a xenophon filter holder
they cost about 30$ or 20$ and are on ebay often

they go behind the lens can be secured by velcro and take 3" filters

series ix goes to 85mm lens diameter. sizes larger than series 8 VIII are few and far between. check the ebay dealers as they may have one but not have it listed.

I went through this with Commercial Ektars and Ilex (Ilex made a boat load of Caltars) trying to find just the right Series adapter is a nightmare. If you are willing to spend the money this is SK Grimes bread and butter. Fuji made an 85mm plastic slip on lens cap, you need something like that that will take screw in filters. p.s. the aluminum Kodak series adapters scratch the outside of the lens barrel. You definitely deserve filters on that nice lens!

Thanks everyone. My concern with putting the filter behind the lens (inside the camera, right?) is that I'll be stuck composing and focusing through a dense green filter. Maybe it's not a big deal though...

A series slip on filter is the way to go. That is what I use for my 4"x5" cameras.

Heliopan was offering a filter holder with 86x1 thread to attach by bandage on lenses with 87mm diameter. That one should fit or could be made fit.
It is no longer listed in the current list burt was in their last, and thus still may be in their stock as surplus.

For small lenses without a thread I use a Universal Adapter Ring made by Cokin, it's called A275. Too small for your 85mm diameter, of course, but maybe you could make or find something similar.

I have a calumet rear mount gel/filter holder you can have for let's say $5 + shipping, that should do the job.

I'm definitely interested, but can you send me a camera snap of what it looks like just so I have an idea? Thanks.

As others have said, the slip on series adapters were the old way to do it. BTW, series 9 filters should be big enough and were one of the most common sizes for filmmakers back when 16mm was big, they fit the 10x zoom lenses which had big front elements.

It looks like this, I think it takes 3" filters:
