There is a mirror under the ground glass, you may want to check whether its not displaced. otherwise (if the screen is inserted correctly) it may be that it doesn't have the exact same thickness and that's what's causing a misalignment. If your camera taking lens focuses correctly at infinity...

@Sanug @retina_restoration @Marcelo Paniagua @snusmumriken thanks for your replies. Pretty sure now that it is normal.

I have a question for fellow Rollei 35S owners regarding the shutter. On my camera, when I select a slow shutter speed (like 1/2s or 1/4s), the exposure seems to end prematurely if I release the shutter button quickly. However, if I press and hold the button down for the full duration, the speed...

Any updates? Has anyone ordered from them and received anything?

Has anyone got any experience with the online shop cufeel.com? They offer very rare spare parts, for example for the Ricoh GR1. But there is no physical address anywhere and the email is at outlook.com. So seems a bit sketchy. You cannot even see which country they‘re from.

There are 4 screws securing the front plate, they are below the letherette at the 4 corners of the front plate. You also need to remove the knob that locks the flash socket. Best you can watch some videos on youtube, like those by mikeno62. Depending on your exact model there may be other...

But shouldn't there be a way? I read somewhere that it is common that with age you have to tension the roller more and more to get the speeds to the normal timing (otherwise they become too short). In my case I got the timings right but I think the tension is very high, because the sound is...

Thanks, thats already a first step, but I thought so far. So how can i decrease the central spring tension without affecting the other 2?

Does anyone know how to do it?

Thank you for your reply @koraks. I completely understood those implications and that's why it was important to me to underline that these are two separate points. They just came up at the same time. I tested the lens with a serviced M-Mount camera and it is consistently off in the same way as...

Does anyone know of a youtube video or a website that shows how to adjust the tension of the first curtain? I know the second curtain can be adjusted with that screw on the side that rolls the entire lower curtain roller. But how can I decrease the tension for the first curtain?

The topic was merged by the moderator, which made it less clear. These are actually two separate unrelated questions. 1. I would like to have an absolute calibration of the camera rangefinder based on a specific protrusion distance of the rear of the lens towards onto the rangefinder lever. I...

Only the front plate. You can access the shutter from the front for most common servicing things like cleaning the slow speed gear. Didn‘t need to take it out entirely. I imagine that it could be risky as it could mess up the synchronization of focusing plane with the focusing knob so the...

I need to adjust the infinity on a Summicron M 90mm F2 lens made in Canada. I tried disassembling it, but I cannot find any shims or anything that would allow that. How do I adjust it? I think I would need to move the optical assembly like 0.1mm closer to the camera at infinity.

Couldn't find this info anywhere. I was trying to adjust my cameras rangefinder, however I also wasn't sure whether the lens is set up correctly for rangefinder coupling (I also had the lens disassembled). So finally I just measured the distance at which the rear ring, that presses the...
