Hi
I just bought a Yashica Mat 124 G.
It seems to work perfectly (I know when i have developed the film)
The viefinder though, looks like its been used as a vacuumcleaner. Before I rush out to get me some of those tiny screwdrivers to take the top off the camera I would like to know if its the right aproach.
Yours Sincerely
Soeren Nielsen

remove the four screws and the hood lifts off--nothing fancy--sometimes you may have to straighten the "wings" that protrude from bottom of the hood when you reinstall it. Be careful of rubbing on the mirror--it is first surface coated and can easily be damaged.

Hi Ed
First surface ? I understand what coating is but
could you explain this ?
The glass is frosted on the underside, right?
I was thinking about just dusting it off with a brush and som compressed air. If that is not enough is it possible to "wash" it ?
Thank you
Soeren

No, a first-surface mirror has the reflective coating (silver or aluminum) on the top surface. (The viewing screen is frosted on the bottom; that must be what you were thinking of.)

You can clean the mirror using a non-oily solvent; my preference is alcohol (methyl or "denatured" is what I use, but you can also use ispropanol alcohol, which is available at the drugstore--just not "rubbing alcohol", as it contains too much water). Use a clean cotton swab and very gently clean the mirror. Be sure to blow off any dirt first so you don't drag it around and cause scratches.

Actually, I wouldn't use anything on the mirror except air and a very soft brush unless there's some kind of schmutz (dirt or stain) on it. The less you mess with it, the better.

Oh, I forgot to answer your question, which is to say yes, you can wash the viewing screen. Just use ordinary window cleaner and a clean cloth or tissue, then blow off any remaining lint or fibers.

Are there spacers in the 124 G? little washers or disks that level the finder glass. I've seen some TLRs with these. they tend to fall out and disappear. Gawd I hate when that Hppens.

Hi
ups seems like I missed the Mirror part ;-)
Thank you David for the explanation on the first-surface coating. Yes I realy must be gentle cleaning the mirror. Out of curriosity, is the mirror responssible for the dark viewfinder due to the coating. As Kevin asks, are there any loose parts likely to disapear except for the screws.
By the way, I developed the film yesterday, Wauv it`s realy sharp and those details, astonishing.

unless the mirror has been damaged or badly deteriorated for some reason, it would not cause a dark image--It will not be as bright as you would see in an slr--nature of the beast. Have seen any spacers shimming the hood on a 124g.

Hello Soeren,
I don't recall there being any spacers when I dismantled my 124 to clean the viewing mirror & lens. I have high resolution gifs & jpegs of both the disassembly manual and the user manual. I would be happy to email them to you - drop me a line at [email protected].

regards, Tony Armstrong
