Hey,
my Yashica 35 GSN is in very nice shape and everything works fine.
The problem I have: the rhomb (in German we would say Rhombus - hope you get what I mean) is missing the left edge.
Not by very much, but you notice it.

So my question is, is it gone or is there something wrong in the viewfinder? (I am not very eager to open it, a big fear of breaking)

Also, when focussing on something near, the 2 pictures align correctly but one is a little higher than the other.
For far distance objects there is no such problem (maybe just to little to see?).

Thanks in advance
Gregor


EDIT: Just wantet to say that I got this beauty from the owner who bought it in the 70ies and he really treated it with alot of care.

not sure what you mean by missing the left edge.
The rhomb is not a rhomb, the left corner being cut off?
I don't think it is a problem, it's just something shadowing it probably. As long as it's big enough:)

The other problem you talk about is vertical misalignment. There are two screws you can turn to adjust alignment. One of them is accessible by removing half of the hot shoe. Lift the shiny metal plate on the hot shoe up on the backside and push it forward to slide it off the camera top (or the other way around...lift it up in the front and slide back). This will reveal a hole. Deep in there a screw is acessible, by a small flathead screwdriver. You have to put the screwdriver deep into the hole perpendicular to the camera top.
 
Thanks for your fast reply.
Yes, you got it, the left corner is being cut off. I think I'll stop my concerns from now, since there is no real disadvantage while using it.

Going to try the screw thing now!
 
Tried it with the screw but that one didn't help. I guess the other one is much harder to access?

While opening the hot shoe and looking inside with the help of my mobile's light, I saw there was something loose in there.
So I started to take the whole top of, but when I had opened the battery test frame, a small part of a mirror fell out.
I guess this is why I am missing the left corner of the rhomb.

Which leads to the question, if the false alignment is also because of that?

I would love to repair that mirror, but first of all I would have to find one and then have enough trust to do it myself.

And I wonder how this thing broke?

...so where is the 2nd screw? ;)
 
If someone has that mirror left over from a broken one and is able to send it to Germany, I would try the repair myself.
Thanks!
 
FWIW, and please correct me if I'm wrong, the vertical RF alignment screw seems to be a tiny one which can be easily accessed by removing the battery check cover.

It can be seen in this picture
(part of Mikes Yashica Electro 35 Pages). It's that little screw on the back of the RF mirror.

BTW, first post, hi all, newbie GSN owner here :)
 
i think fonso is right. That tiny screw is indeed tilting the mirror. Sorry baout my my mistake. Hope you did not misalign the horizontal one :D

I'd say dont worry about the cut-off edge as long as the rest is there. It would be difficult to find a replacement part, unless you find an otherwise broken GSN and take it out from there.
 
Pherdinand,
A few days ago, when trying to vertically adjust the rangefinder, I actually tried the one under the dust cover. When it was clear that wasn't the right one, I found the pic I linked to in my previous post, titled "Vertical rangefinder adjustment screw". And then, of course, I spent some minutes trying to make the vertical adjustment by turning *the big black screw* that is seen in the photo! :bang:

:rolleyes:
