Vintage Filter Systems: The "Series" Filters

Series V Yellow Filter on 1950 Ross Lens, Ensign 820 Folding Camera. While there is a plethora of information available in books and on the Web about vintage

i measured 29.3mm for the thread. Selon Skgrimes (link at end of message)it should be M30 x 0.5. 29.3 + 0.5= 29.8 rounded M30 x 0.5 filteradapter. Heliopan should have them maybe also rafcamera. he can deliver through austria and lithuania if the other two countries are not welcome. see news he is also on ebay.
could get a real 29.5m series VI adaptersystem or rafcamera M29.5 x 0.5-M52 adapter. it should not interfere aperture lever a bit inside 58mm means adapter 3mm inside.l 58-52/2= 3.

pls correct M29.5 or M30 x 0.5 filtertread. i think i will buy the M29.5 kodak series VI system.

How to measure threads

There are many cases where accurate measuring of a diameter or a thread is necessary. Most equipment today has been standardize, but older equipment and niche items require accurate measurements. This page provides some guiding information for measuring threads. Metric and Imperial Threads...

Its 29.5x 0.5 tested with Rafcamera M22-adapter x M29.5 x 0.5M.
will go this way. Rafcamera M29.5x0.5M - M52 x0.75. hope he makes M29.5 x 0.5M - M34 x 0.5. can then use heliopan brass adapter nr 628 49/34. they also have 52 and 55 counterparts.
Or phototools(now also with brass-adapters) has direct brass adapter, maybe better leaving base-adapter M34 on lens. now the question which sunshade. angle about 42.5 mm equivalent.

just got Rafcamera M29 x 0.5-M52 x 0.75 filteradapter no brass. if he makes M34 x 0.5 on could use e.g, heliopan nr 628 49/34 brass adapter. or larger M52 or M55. big question which sunshade? 140mm for 70 x 123mm.

Dont understand why there is no lens thread-list of those Kodak Autographic cameras.
Yes was so stupid to open first the back before checking if there is film inside. its now wound on takeup-spool and waiting for further investigations. Verichrom(not chrome?) V130-6 FPK 2C-6. clear which film for which camera and how many images. so must be around 120 lenght.
As i said i tested with 4.6m of normal thick CN 70mm film Agfa XRS 400? if i dont err. cartridge removed since 70mmspool only working without on left donorside. UPDATE: Do the same in real world but go from 70mm film STAYING INSIDE CARTRIDGE. Mount first takeup spool!!! in daylight/subdued light. always keep old cartridges under pressure and slit tight enough to not risk lightleak. Must first test this new idea since will finetune now how many turns must be made. first simple one leading to almost overlapping around image 8. details follow. one must anyhow calculate missing two shots on 4.6m of film(maybe only one see later) means not 28 but 27or 26 images. why? 70mm film can easily be developped with existing reels be them Jobo or Paterson. many hints on the net see rangefinderforum 70mm fun and nokton48. but lenght will be 220 around 172cm in my case since i used official jobo 2517 reel. it can be used with 500ml chemicals in 2820 testdrum(print)-sorry in older thread i have written 2520. 2820 is true. print-testdrum!!! yes dual 2520 reel-method should also work i tested with water. its waterproof despite reel-combo(three parts) a bit higher.

In those days, for that type of camera, it seems that filters and lens shades were not in common usage. They are not discussed in the camera manual at all. The only similar mention is a portrait attachment, whcih was a slip-on type.

This Kodak catalogue from those days mentions skylight and color filters and states that they are slip-on type filters, like the portrait attachment.

From experience I can assure you that fitting your lens with a series filter slip-on adapter will be the best solution. Measure the oustide diameter (OD) of the front lens cell to determine which adapter will fit. Series adapters and filters are not difficult to find in the US; not sure what your experience will be like in CH.

You might find this interesting, my experience with a similar, but older, Kodak folding camera. Using it is a lot of fun and the resulting images are much better than I ever expected.

1906 Kodak 3A

The Kodak No. 3A Model B2, which I have adapted, was made between 1904 and 1906 as far as I could determine from the available literature. It was a "Pocket Folding Kodak" but pockets must have been very big back then because this one measures (in inches) about 10 x 4-3/4 x 2. The No. 3A was one...

Code #'s and sizes for series filter adapters. Basic sizing info.

www.robertallenkautzphoto.com

had a debate with him about lacking informationen about innerthread 29.5 x 0.5 or stickon-outer diameter here 33mm. i dont wanna be limited to what the system can offer. the only concern is sunshade-size. maybe best to use M49 x0.75 filters but which sunshade. 49mm standard ones are much bigger than the kodak series ones. maybe leica-dimensions on ricoh rangefinder?
Custom Photo Tools doesnt have the right adapters. Maybe it could be wise it use no brass-adapters and rafcamera makes a direct M29.5 x 0.5 - M34 x 0.5-adapter and resp. filters and sunshade will be used.
yes i went again through the manual. its more a photographic lesson and how to develop the film incl. using the special flash system.
i was already on ebay checking the 33mm and 29.5mm systems. if i need other filters than the limited ones system VI can offer i have a big problem.
