Click stops not clicking on Componon S

[Robert Oliver]

I just received a 150mm Schneider Componon S from the bay... Glass is perfect.

The click stops aren't working... Just turns smoothly no matter which position the switch is in.

Anyone knows if this is an easy fix? If not I will just make a small led flashlight to light it up (since it's not illuminated anyway)

I have a 135mm Componon S that's similar, mine came off a roll-head printer turret where all the lenses were preset/calibrated and locked to a give the same exposure (time) by a Durst technician. I'd quite like to have click stops.

Same here! My 100mm Companon S began to lose its clicks quite some time ago - and now they're barely there. I'd love to have the clicks back - and am usually pretty good at DIY stuff - but so far I'm still scratching my head with this one! At any rate...if anyone could chime in on the best way to take this apart and fix the clicks - that would be great!

is it not like the rodagons, you can pull the aperture ring out for stopless or push it back in for clickstops?

The ball and spring can get gummed up. No big deal to take it apart. Just don't lose the ball or spring, otherwise you will be without the click stops forever. I will say that on my 150mm Componon-s, even after cleaning the grooves, the ball and the spring, the click stops were still weak.

Expect to find something similar to this when you take it apart.

Thank you!

The only lensboard that I have that fits is recessed, which makes it really hard to see the line.

It wouldn't be a problem with working click stops, but what a PITA without!

On a Rodagon you pull the ring out and rotate it to set the preset aperture and then push the ring back in. To engage or disengage the click stops you slide the switch.

... or someone previously took it apart and the ball/spring became lost.

Not working on mine. With switch engaged I get the slightest hint of a click, but not enough to set the aperture by. Trying to figure out how to get barrel apart. Looks like this retaining ring is my only option.

I'm going in....
