Hello,
The Koroll (S) is an 6x6 camera but with the suitable mask it is suitable for making 6x4.5 negatives (on the back are two windows for the filmcounter).Problem is:everyone is talking about this mask but I have never seen one.
Of course I can make one myself but I wonder:has anyone seen the original one? |

I haven't taken mine apart to see the exact construction, but just looking at it, it appears to be two pieces of U-channel mounted just inboard of the rollers.
Could dismantel it for better photos and measurements of the pieces. Might be a couple of days before I get to it.

That would be great ! I do have the hood,filters,case and even the little cardboard box for the filters and a home-made mask will do the job for me until I find the original one.
take your time, regards, Paul |

Paul, took some photos last night of the masks. There are actually two, one for each side, and they just slide in. If you look at it end on, it looks like an art-deco style 7. The downstroke curves a bit to make it spring loaded, and thus hold tight inside the camera.
It measures 3.6mm on the up stroke, 6.7mm on the cross stroke, and 25.7mm on the downstroke. the lower corners are rounded to comply with the inner shape of the lens chamber.
I'll get the pictures up tomorrow. I've got two sets of yellow filter+hood for mine. One came with it, and the other I bought when I forgot I had the first set. It also came with the lens cap, though I only have one of those.

Paul, photos of the mask inserts for 645 negatives on the Koroll.
As Installed
One Removed
Mask End
Mask Side Towards Center Of Lens Chamber
Mask Side Towards Lens Chamber Wall
The mask is 57.5mm wide, tapering down to 57mm at the start of the radius cuts on the corners, which are 10mm. Metal thickness is 0.4mm
You can see the round detents just inside the lens chamber that the curved portion of the mask slides behind, in order to hold it in place tightly.
Hope this helps.

Thanks Phil,
This is the first time I see pictures of this mask.I think you're just lucky to have them sit in the camera upon purchase.(and most sellers dont know they are there or not)
I think every household in England has such a camera in the attic .They are quite affordable, except for this one.

Thank you for this information.
kind regards, Paul. |

You're welcome, Paul. I was extremely lucky on that camera. And I came no where near paying what the buyer did on the one you noted.
