    Filters for Zeiss Ikonta

    Santa showed up with a Zeiss Ikonta 6X9 sporting a Tessar 10,5 cm lens with Compur-Rapid shutter. There is no threading on the lens, so I can't tell how I could attach a filter. I didn't see anything on B&H other than threaded filters. So, I am in need of education please.

    Thanks

    Jim

    Hi Jim,

    I have no experience with Ikonta, other than a lust for one... but most lenses of that description use push-on filters. One way is to use Kodak series filters (series number indicates the size, Google the Wikipedia "filters"). You'd meaure the outside of your lens, buy a series adapters in that size, and then the filters/hood goes into that. The filters have no threads but sit in the adapter and are held in with either a retaining ring or a hood. Series adapters, filters, and hoods are still fairly easily available on ebay.

    Zeiss produced a series of push-on filters in a number of sizes. I don't know if these are available new, but they are fairly common on Ebay. I suspect you are looking at a 32 mm fit - that is the size of all my 1930s Zeiss Ikon folders.

    You've got yourself a really great camera. Here's an article that explains Series filters.

    http://silverbased.org/series-filters/

    They are sized in Roman numerals. My Ikonta 6x6 with a 70mm lens uses a Series VI. As Peltigera says, that might be the size you need, or maybe a VII. Don't bother looking for anything new as this whole system has been obsolete for about 40 years. You can usually find them pretty cheap at photo swap meets.

    I have a very early vintage Ikonta Super C 6x9 530/2 with a 10.5cm Tessar f/4.5 SN1538091 in a Compur Shutter SN12225524, Zeiss Ikon body SN Y 55030, which may match yours. The lens takes 37mm push on filters and hoods. The Zeiss filters and hoods are sized to enable some stacking. However, my camera will not close with any filter in place on the lens. I found the filters readily available on eBay several years ago (ca. 2010 is about when I accumulated them), and in surprisingly good condition.
    The camera is a joy to use and behold, and the Tessar produces its classic magic, surprisingly nicely in color as well as monochrome despite its lack of coating. I consider the camera one of my most fortunate finds over my too many years of over-accumulating gear. It was my first and remains my favorite folder (even over a Bessa RF with f/3.5 Heliar, nice images, but nowhere near as pleasant a shooter).

    I have an Ercona II, an East German Ikonta with CZJ Tessar, that works with 37 mm push-on filters. It is a bit tricky, as they go down into a deep groove in the lens barrel. It looks to me as though a 40.5 mm push-on might work over the outside of the knurling too, though I've not tried it. So far I have some 37 mm push-ons, and have also lightly machined a Series VI push-on adapter to fit in the groove and use series filters already in hand.

    Unfortunately, 37 mm push-ons apparently fit the Voigtländer Bessa II, which adds some collectable value to the prices, especially the Voigtländer branded ones. I've not found them as common on ePrey as i had hoped. I can't remember when the transition occurred, but it seems series filters went the way of the dodo several decades back.

    I have also read somewhere that the knurling on the Zeiss ikonta actually has a screw thread as part of the pattern and that there were female threaded 40.x mm adapters or filters, but I've never seen anything to confirm that notion. And I don't know if all vintages were that way; my Ercona appears to be a straight knurl, no thread.

    As someone upthread noted, the camera doesn't close with a filter in place, a compromise for compactness when folded. They are really nice cameras -- even my East German imitation (which actually came from the original Zeiss plant).

    You should be able to buy original Zeiss Ikon-branded filters for a reasonable amount. I think that I paid on average about $5 for each of my filters: Dark red, orange, green and yellow.

    I also found a nice push-on lens shade that came with a bunch of other things.

    The later Ikonta cameras used filters that screwed onto the outside of the lens: 35.5mm filters for 6x4.5 and 6x6 and 40.5mm for 6x9.

    These filter sizes were also used by other Zeiss Ikon cameras (Ikoflex, Tenax II, Contax, etc.).

    Enjoy that camera. I've made some great images with Tessar-equipped Ikontas and Super Ikontas.

    Larry, does your camera have the plunger release next to the shutter or a left-hand shutter release on the body?

    Just curious. I have one with the plunger and a second with the body release. This camera does not have double-exposure prevention.

    And I agree that it's an outstanding camera to use, and the photos are top-notch.

    You could try E Mailing a UK company called 'SRB Griturn'. Just Google the name. They custom make filters of any size and fitting and push on filters are probably a stock item anyway

    Hi Mike,
    My camera has the plunger type shutter release at the bottom right (facing forward) of the shutter assembly, at the front of the camera, below the armature for the rangefinder window and focusing wheel. That shutter and focusing control location took a bit to become familiar, but now I find that when my right hand is well positioned for focusing or firing the shutter it is helping to stabilize the camera as well. My camera also does not have any double exposure prevention mechanism. It's a simple mechanical winder below the takeup spool with red window frame counting and nothing to keep you from winding past the next frame, or more should you really lose your concentration. Remarkably, despite the simplicity, the frame spacing is right on when the camera is correctly wound according to the frame numbers in the appropriate window.
