This one is a Franka "Rolfix" folder.
It is missing the mask for 6 X 6.

I jumped at it over this:

... and may have jumped the gun.
Rear lens element is spotted a bit.
If I can find, or make a square edge spanner, I may be able to deal with it.
The Prontor-S shutter is in very good shape.

Bellows shows signs of moisture, but I just HAD to add a Schneider lens to the stable.

Missed out on a 155mm Wollensak. Body was being sold with no plates or film back, and his asking was a little too high...

Regards,

Doc Sharptail

Another folder.
Kodak "Jiffy Six-16".
It isn't 120 though- it's 616, which is approximately 2 1/2" wide.
I'll have to look again, because the image is fairly wide- 4" or so.
I probably won't get into trying to run 120 film through it.
That process is fairly convoluted, and known to not work very well.
I like the front plate a lot.
I will try and get up some detailed photo's later, after I dig out the 55mm micro.
Didn't pay a cent for it either. Daughter found it some-where...

Regards,

Doc Sharptail

Keeping them dry and folded goes a long ways to insuring longetivity.
The German folders had a different leather treatment than Kodak's, and lasted a lot longer. Exposure to the acids in tobacco smoke is very hard on extended bellows.
To keep them in good shape, store them folded when not in use.
I have to light test the bellows on the Franka Rolfix camera. There are moisture marks on the bellows, and fungus spots on the rear lens element.

Here are a few pics of the Jiffy Six-16:

Front plate after a light cleaning. The prismatic mirror in the finder for verticals is flopping around. I will have to either re-glue it, or replace it if it's a broken corner.
I have it on good authority that some mirrors in make-up kits are ideal for this task...

Image

Manufacturer's marks under the carrying handle.
There is a sticker under the film back with patent up-dates to 1936, including a first patent for Canada. Same sticker also lists recommended Kodak films for the camera.
I will get a photo of that next time I have the camera open.

Image
Film winding "key" on top of the film box. It shows film size information.

Image

Bellows extended.
The lever on the back of the lens board is the shutter lever. Moving it trips the single blade shutter at approximately 1/25th sec. exposure time. There is another lever on the bottom of the lens board to set the shutter to "T", or time. The shutter will stay open until the shutter lever is activated again, then the blade moves to the closed position.
Small button on the top of the film box is the bellows release...
There is an aperture tab on one side of the lens board.
It is a simple blued steel sliding plate with three different sized holes in it for f8, f11, and f16 from what I've read on the internet.
I downloaded the user's manual for it off of the Butkus site, and there is no info in it about using the aperture, except for uncoupled flash/photo lamp exposures~ both requiring the "T" shutter seting.

Regards,

Doc Sharptail

This camera made 8 images, 2 1/2" X 4 1\4" on a roll of 616 film.
It takes me a minute to comprehend a negative of that size from what some considered to be a large "pocket" camera.... :-o :-o

The 620 version may be worth looking for. It is more easily adaptable to 120 film, simply by trimming the ends of the 120 spools.

Regards,

Doc Sharptail

Just put a roll of FP-4 Plus into the camera at the top of this thread.
Did a quick L.E.D. lamp test on the bellows, and couldn't find anything.

We shall see in about ten days time, I think.
Messed up the first frame loading the camera with the shutter locked open on "B" :oops: :oops:

A friend made 3 1/4 X 4 1/4 sheet film for me by cutting down 4X5. Worked fine, but when I found a 4X5 Speed, the smaller one went to a friend in Kiev. SW

When I was at K.U. we had a graflex type sheet film camera and it also had a polaroid back. Out of curiousity I put a German made Vivitar 5.6-80mm enlarging lense on it and shot a couple of images. They were outstanding.

I found out later this was a probably a house branded Schneider companon lense.

It was 6 elements in 4 groups.

I am a bit anxious over the spots on the rear element of the Scheider above.
It is not much more than a standard Cooke triplet in construction- very simple.

I do think enlarger lenses from the mid 70's period onwards are much better glass than the late 40's to early 50's glass on these 120 folders.

Despite that, the images made and shown in the birthday gift thread are still impressive- considering what they were made with. I think luck had a great deal to do with that. I am going to tweak a couple of those in digital post-processing to show what the prints actually look like...

Regards,

Doc Sharptail
