Holga Pan 120 and conversion to Super Angulon 90mm F8 lens

[xya]

The most common thing I've seen is place slider in "12" position and expose on odd numbers; 1,3,5,7,9 Is this the correct sequence for 6x12 ?

It's nearly correct, add the 11. You get 6 photos. See https://www.oddcameras.com/holgamods_612_pan.htm

Yes the Holga 120 Pan uses number #1/3/5/7/9/11 for 6x12 frames. Ironically, Belair 612 (another cheap 6x12) use number 2/4/6/8/10/12. I used to get confused every time, thus in the end I have to print out a label right on the film back door as reminder.

In terms of seeing numbers through the red window, I find Arista EDU Ultra 100 (Foma 100) has the best visibility for numbers on the backing paper.

Thank you. I also forgot to re-install the 612 mask. My first roll should be interesting.

 

[MTGseattle]

Ok. First outing went ok.
Frame spacing and film spacing were predictably weird with the 612 mask left out.
The lens (90mm Congo) seems great.
The disappointment is that in the roll with the 612 mask installed, I’ve got a nasty scratch running through the entire roll.
It should be easy to locate the offending burr or whatever based upon location on negatives.
I also don’t seem to have any weird light leaks. It was bright yesterday and I didn’t shield the camera any more than I would any other camera while

Oh, film: both Fomapan 100. 1 roll of latest blue/yellow box “profi classic” white baking paper.
The other roll had black backing paper.
Rodinal 1:50

I did some investigating, and there were some burrs on the back plate. I sanded them with some 1500 grit paper and did a quick swipe with Acetone. I should be able to expose a "scratch test" roll today to see if that fixed the issue.

nice images @blee1996 Is there a subtle color shift happening? I know nothing about that particular film. I really need to get some rolls processed, I have quite the backup right now.

The Agfa Ultra 50 was a very contrasty and "color incorrectly" vibrant to start with, plus this roll is over 2 decade expired. Even with standard C41 process, I won't be surprised that there are color shifts and stuff. So I'm using it as it is, for its unique color palette. This is an accentuated version of colors in real world.

Congratulations @blee1996. Apart from nice composition and vibrant colors, My eye caught, and calculation verified, that your aspect ratio is >2; 2.30 in fact. Which I find nice, 2 being IMO a little short of panoramic. But how did you manage to achieve this with 120 film? Could it be that you pushed the width to the limit allowed by the Angulon coverage, and then had to devote not two, but three regular frames for each panoramic shot?

The Holga 120 Pan natively supports 6x12 frame, but as you noted the 6 is more like 5 while 12 is pretty true to length.

The Angulon 90/6.8, when stopped down to f/11 or smaller, seems to cover 6x12 ok. There are still some vignetting in the four corners, but not too bad.

The reason I chose the Angulon 90/6.8 is its much smaller size, which fits the toy-like Holga perfectly. a Super Angulon 90/8 will definitely have more coverage, but it will not hack nicely into the small camera frame of Holga. I have another 3D-printed 4x5 point'n shoot camera, which uses the Super Angulon 90/8.

I finally processed my test roll that I hoped would be scratch free. It is not.
When is the film under the most tension, close to the feed/takeup spools, or when ready for exposure? My 1st and last frames have no scratching. Does the actual film contact the 2 pieces of foam inside, or does only the backing paper rub against those?
My sanding effort seems to have changed the character of the scratch but not fixed things, I guess I start with another round of sanding and another cleaning effort to rule out a piece of debris.

Sorry to hear that. My Holga 120 Pan does not have any film scratching issue, and I have not modified anything related to the film transport path.

 

[MTGseattle]

I haven't modified the film section at all on mine either. it came out of the box with a piece of foam in each film spool location which I imagine is to keep the spools from moving around inside the camera.

Do you have the 6x12 plastic mask installed?

 

[RalphLambrecht]

I will be getting a Holga Pan 120 soon and am wondering if it is possible to convert it to accept a Super Angulon 90mm F8 lens in Copal shutter? I see references to plenty of conversions to the 90mm Angulon f6.8 but cannot find any reference to the Super Angulon. I have a machinist friend who can handle any machining required. Any comments or insights gratefully received.

You are aware, this is against the basicidea of using a Holga?

And what basic idea is that?

 

[MTGseattle]

Yes, 6x12 masking frame is installed. I didn't feel any burrs on it, but that's a good step in the trouble shooting tree since the roll I exposed without the frame wasn't scratched.

@RalphLambrecht I can't speak for everyone, but the point of this particular Holga thread for me was getting "good" 6x12 negatives with a minimum budget compared to the usual options (612 backs, dedicated 612 cameras, etc). For the true Holga experience, I have a 120N somewhere around here.

If you ever sell this other camera, I’d be interested. I’ve been looking at the 3d printed malefic camera but saw that this would come out cheaper.
