Yeah my Super Ikonta C lens is a Zeiss manufactured in Jena...prewar and pre-iron curtain. I consider it to be fully "Zeiss"

BTW folks...This is the kind of thing you have you watch out for when you try to follow Gene M's photographic "Lead"......<div></div>

Ralf- the camera was a Zeiss Ikon Super Ikonta C with a 3.8/10.5 cm lens. I also used a Zeiss Jena Yellow D filter.

Ok I lied.....<div></div>

...last one<div></div>

Some more....<div></div>

And another....<div></div>

I was roaming around the hills south of Dallas, and came across a historical

farm site called Penn Farm. It was continuously used as a farm by the same

family (forget their name....) from the 1850s to the 1940s...when there land

was flooded by a useless recreation lake.

 

As I wandered the acreage, I saw these structures and immediately thought of

Gene M....

 

Gene M., I hope these meet with your approval! BTW, I am now processing my own

BW, quite frankly, because of the interest you sparked for me in doing it...<div></div>

No such luck Danny. I got mine from a seller in Italy, via e-bay.

oh..yeah sorry- Look for anywhere between 250-400 on ebay depending on the frenzy.....

....A better shot of the lens assembly....<div></div>

Here is mine, which is of an older run. The lens SN indicates late 30s...the presence of the decorative round silver take up "spool" was also dropped in later runs. A very excellent camera. Take a look in my portfolio; I have several shots with the camera in there.<div></div>

....Here is a shot from another Zeiss...this time the Ikoflex Favorit- 6x6 cm negative.<div></div>

Nice shot Ron...I love my old Zeiss (531/1 Ikonta C). Here is a sample>>>><div></div>

No solution....I just like the effect<div></div>

...cut back to one can of cat food a day and get the camera! Nice pic!

Christopher,

 

I have characterized the filters using my light meter, so I will use the filter factors I came up with until experimentation tells me to change the numbers. I will check with the historical society folks to see what they can find out. I have no idea as to the vintage of these filters. Some are labeled "Zeiss Ikon...Made in Germany" and some are labeled "Zeiss Ikon Jena." It would have been too easy to have the filter factor stamped right on the ring.....

 

Thanks to all....

Michael,

 

that seems to fit...the R (red) 10 looks denser than the B (blue) 40 and the GR (green) 55.....The reduction in light (as measured by my lightmeter) is appropriate with the VLT theory. The lettered filters are marked "Gelbglas D X 37," and "..L X 37." I know "Gelbglas" means "yellow glass," and that 37 is the size...but the D or L- I have no idea!

 

Thanks!

 

John

to further complicate things, I have some Zeiss-Jena filters that appear to use a lettering system....i.e. L, D (green filters both). Anyone, Bueller, Anyone?

Ok...I have exhausted Google! I have a few vintage filters from Zeiss Ikon.

They are designated (using the Zeiss Ikon product numbering system) 351/10,

40, 55, etc. They call the red one R 10, the blue one is B 40, and a green

one is GR 55, etc. These do not follow the Wratten numbering system. I am

trying to nail down filter factors before I take these into the field. Does

any one have any information about the Zeiss Ikon filter numbering system, and

how it relates to the Wratten system?

 

Thanks!

I have an Epson 4990 that I use to scan my Super Ikonta (6X9 cm) negatives. Works pretty well. See my photos, there are several shots in there taken with my Super C, or Ikoflex Favorit and scanned using the Epson.

Plus...the taking lens is easily unscrewed and replaced with any of the same size/focal length Tessars. Not saying that is what happened with your camera, but it is very easy to do. It wouldn't surprise me that many of these older TLRs don't contain the original lens. Someone replaces a lens due to fungus, etc. For example, one of my Ikoflex lens pre-dates (based on the lens serial number) the dates the camera was manufactured by at least a decade. Could be that the lens was sitting on a shelf all that time, waiting for a camera, but who knows, In the end, if it looks coated, it is! All are great cameras...I am a huge fan!

The Rex Lounge looks like my kinda place....Thanks Gene!

David and Robert- thanks! Very usefull stuff! Here is the filter in question. I have no history or knowledge of the brand. I also notice that most references to filters call out a filter number 42B for example. Most of my stuff is old Zeiss Ikon- is there a WESTON/ASA style translation between filter manufacturers?<div></div>

Rob (and all),

 

Thanks, a copy of that would be great. I suspected that my simplistic approach was not taking everything into account. I appreciate all the help. BTW I am off BW400CN, and back on 400 TMax....
