I'm cleaning up a Yashica Electro GTN which is in great condition but has fungus on the lens and lots of grime to remove. I wonder if anybody can help with some questions I have.

1 Is it possible to remove the rear lens group without peeling the leatherette and removing the front plate? In theory it's accessable from the film side, but it seems to be blocked by the square shroud around it.

2 Is it possible to fully remove the sliding contacts and aperture ring assembly without unsoldering all the wires which hold it tightly against the shutter?

3 Has anybody disassembled the shutter and aperture blades? It is a nightmare? The aperture blades at least have a couple of dots of fungus, so it would seem helpful to strip them down. I haven't even worked out yet what to unscrew to get to them.

Thanks!

1. No.

2. No

3. No. But you probably have to separate the shutter from the plate carrying the lens assembly, and this involves some desoldering, too.

Ooh - could you check that link? It doesn't seem to work.

Winfried is right in all three points, but if you think that it is easy: it is NOT, especially if you do this kind of work for the first time. When I disassembled my first Electro 35 I did not exactly know what problems I would be faced with and I was confused by all those colourful tangling wires. Note that working on the aperture requires the complete separation of the shutter from the camera ! I then lost a tiny washer of the shutter mechanism which meant the camera could not be reassembled again. Now that I am aware of the unexpected to happen, this sort of job is a lot easier. I found it helpful to get some basic training on strictly mechanical cameras (Lynxes, Mamiyas, etc.) with no wires in the way.

Well, at least I know I wasn't missing something obvious. It didn't look easy, and now I know it is every bit as bad as I thought. Maybe not bad, I suppose, but a bit risky.

Sigh, those tiny washers, always causing trouble. I'll use the camera until the fungus grows back, and then take a deep breath...

Thanks for the helpful advice, both specific and general. One last question - does the leatherette usually come off in one piece?
