Hi Folks, I have inherited a later model 1B retina (with F. no. around top of the rim) It was locking up after each exposure,freed by pressing film release button alongside shutter button each time. (counter was not at 1!)
But also, the shutter blade don't move, just a tiny click. I would like to remove the front lens to access the shutter blades to try to carfully flood clean them. The front/first element can be removed by unscrewing the lock ring but there is another lens in the outer assembly.I think I must remove this aluminium mount completly, but it feels tight to unscrew? it has a tiny bayonet mount for, I think an auxilary lens (it is not the later interchangable lens).Any ideas, I do not feel competent to strip out the whole shutter/timing mech.to remove the blades for a proper clean. |

To open the shutter on a Retina IB you first remove the front lens group. This is bayoneted into the front of the shutter and prevented from turning by a thin metal spring. You must lift this spring slightly with the tip of a screwdriver to allow you to rotate the lens.
With the lens removed you can see a retainer ring in the centre. You must remove the single black screw that prevents the retainer rotating, unscrew the retainer ring and then you may lift off the lens mount, shutter-speed, and aperture dials.

Hi Chris, thanks for that. I did check your wonderful new web pages, but the upmarket 11c/C was highlighed, with the fully removable lens.The 'fixed' Xenon lens on the 1B seemed different.I did see the tiny spring clip alongside the lens rim blocking rotation, but not wanting to force anything I thought it prudent to ask the experts, got THE expert replying!
I noted your archive comments on this forum, re.checking/setting the tiny release button that is also locking the shutter, think I have 2 probs. shutter blades now stuck 1/8 open not allowing wind on cycle to operate, will have a go tomorrow! many thanks Ted |

Hi Chris, previously, I was trying to push the clip inwards, it needed to be lifted slightly and pulled outwards, lens then came off OK!
Just one point, does the film release button/double exp. lock have to be pressed in every time to enable the rapid film winder to be advanced? seems a bit of a faff to have to do this for each exposure? OR do I need to adjust the screw under the shutter button ?(with top removed)

G'day Ted,
No, a photographer would soon get pissed-off if they had to press the film release button after each exposure. That sort of thing went out of vogue in the thirties.
The adjustment must be well-out. The film advance should be freed-up at the same point in the shutter release button travel as the shutter is fired in an ideal world.
The existence of the film release button serves as a sort of 'emergency release' if for some reason the shutter release button doesn't release the film advance interlock, or if the shutter isn't actually cocked because it is faulty.
If the shutter isn't cocked, then the shutter release button is blocked from moving.
Regards, Chris |

Hi Chris, thanks for that, I downloaded instructions from Mike Buctus site but the info. seemed to suggest the button was a sort of safety lock? to prevent double or wasted exposures? Some sort of Kodak belt and braces? I remember I had a Welti 35mm that had a nightmare of little levers to prime, in order to fire the shutter!
Now I know it is out of adjustment I will have a go at resetting it, I recall it was mentioned in an archive post? regards Ted |
