MM shutter speed dial noise

Hi,

 

I recently had my MM into NJ to deal with a CCD line issue that has been fixed. When the camera came back, the shutter speed dial seems clanky-er than when I remembered it from before. When I compare it to my M240, it’s worlds different.

 

I no longer have an M9, so I can’t quite compare it to that, so I’m not sure if something is worse or if I am just imagining it.

 

It seems particularly clanky in the 1000-2000-4000-A-B range. I’m trying to capture it in a recording, does anyone else know anything about this?

 

It’s definitely louder than my M240. I’ve tried to record it here.

I suspect the MM has the same shutter, and noise, of an M9, M9P, or M-E, aside from the sensor the mechanisms are identical in all. The shutter itself is a touch louder, just a touch, than my MP. The subsequent reset sound of my M-E is probably about the same as the sound of manually advancing the film on the MP. But all in all, pretty discrete.

 

I haven't listened to an M240, perhaps it's as quiet as the MP.

Fair point, though while we're in crazy land, when I press down on the shutter dial, it has a little give. Do others' do this?

 

The shutter speed dial on my MM also has a little 'give' when I press down on it. Almost like a little click. When I had an M9-P, its shutter speed dial did exactly the same thing. The shutter speed dials on my M2 and M6 are both rock solid - tight, smooth, and precise. I've just come to accept that things were built to a higher mechanical standard in the old days.

 

I'm sure it makes no real difference though.

The shutter speed dials on my M9 and MM behave identically. They are quite 'clacky' and there is a tiny 'give' when you press down on them (not that I'd done this before reading this post!).

 

The MM is 6 months old, the M9 has just been in for service in Germany.

 

My MP's dial doesn't budge downwards at all. Mechanical vs Electronic selector, I guess.

It is perfectly normal that the shutterspeed dial has a little give on all digital Ms, as it is basically a rotating switch on little-ball-and-indentation "clicks"and a spring.

The dial on the M3 through M6 was completely different, as it was the control wheel for a little clockwork that controlled the shutterspeeds.

As far as the clicking on the shutter dial - where was the mic situated when you recorded it? Mine has some clicking, it's really only noticeable if a) you're really paranoid about noticing such things, and 2) if you're extremely close to it. So I can't say for sure about your camera, but I suspect everything is fine. Go and enjoy that lovely MM sensor.

Oh well, I just found this problem in my recent purchased of a used M9. I had my old M8 at hand, and the shutter dial is rock solid without any issues like this. But I also found the right arrow key on the main dial seems a bit "sticky" and keeps skipping the images when you press it to review the next images. Does anybody here have the similar issue? Thanks!

Thanks. I think it's probably the way it was and I never noticed it. Now the light leaking into the rangefinder is another matter.

 

Just pop into a dealer and try and try the dial of an ME/M9 etc., they should be the same.

Light leaking into the rangefinder. How should we interpret that?

 

I may very well be misstating this. The first symptom I saw was the RF patch flaring out more than I’d noticed before, especially with back-lit subjects. I started poking around and figured out how to reproduce it:

 

• Put my finger over the RF window (the little one to the left of the lens facing the camera).

• Look through the viewfinder, point the camera at a window during the day (a lens was not required to get this to happen). When I do this, the RF patch is (correctly) invisible.

• With my finger on the RF window, if I move the camera so that the left third of the viewfinder is still facing out the window, but the remaining 2/3 of the viewfinder is on the wall by the window, the RF patch will re-appear and shimmer.

 

It’s really weird, I’ve never seen it before. I double checked on both my M240 and my M3 and neither of them show this behavior. It’s almost like something was wrong with the silvering of the RF patch.

M240 and M3 are different generation RF mechanisms and not directly comparable. I very much doubt there is anything wrong with the silvering, the RF or, indeed, the shutter speed dial.

I must have too much time on my hands because I've just tried the above with a Monochrom and MP and can confirm that it is normal.
