The front viewfinder construction question in M3!

[mintnana]

Advertisement (gone after registration)

I found out the loosening of the front viewfinder window glass in my M3,

when cleaning up dusts by my index finger with polisher cloth.

 

I was afraid of pushing too hardly and breaking the window glass.

 

But when another M3’s window glass was depressed by finger tip,

the glass was not so stable as I thought too.

 

Both are fragile and unstable to the pressure from anterior.

 

I’m afraid that small particles of dusts, sands, rain drops ,moisture ,

so on such a thing may intrude into the inside of the finder mechanism

from slits between the finder glass and a body frame .

 

Is it default ? If so ,how opposing against the foreign bodies?

 

I think it more stable in M3.

 

Another type of window (for example MP,M6,M9) is rigid ,

not occurring depression against finger pressure.

 

Is there anyone for same experience?

 

How about MP-3 just as same type of the finder as M3?

 

Thanks a lot of practical adovices in advance!

My M3 double stroke from 1957 is quite stable. I'm applying quite a bit of pressure to all three windows, but cannot see that they're giving at all.

 

Good luck.

The front window on my M3 is also kind of loose. I noticed that when I accidentally touched it with my finger.

 

I am not worried about it but am cautious about not touching / pressing it.

Thank you for the first response, David.

 

I really appreciate your trying to make sure it.

My M3 is also double stroke one ,No 75xxxx.

 

I wonder where does the difference come from ?

Thank you for quick reply, mmk60.

 

My experience is not the only one.

That makes me getting relieved about it.

 

I am worry about whether sending my cameras to repair survice or not.

But decided to keep them just as they are.

 

 

I must keep in mind to avoid pushing the window carelessly any more.

 

I made too much rough handling them all this time.

 

 

I wish my tinny posting will ring an alarm bell

on handling the view finder window.

 

Leica M is not always solid.

 

Your folks,

take care with your Leica M gently.
