Question About the Range Finder 'Condenser'

[Xmas]

The 1st Kiev I tried did not demonstrate your symptoms, it did seem to have a horozontal movement as the coincident spot was tracked across the gold patch, but no detectable vertical movement.

I dont think your symptom is due to the eyepiece movement, (you have done). It is more likely that someone has reglued one of the (two) rangefinder 'prism' elements, slightly out of alignment. Is the image concident at close up and at '8'?

Please can you try the same test as earlier with the concident spot just touching the bottom or top of the gold rectangle? If you get the same effect can you repeat at a different distance, preferably '8'.

The reason for the 2nd test is to see if the fault might be in the moving part (of the prism) or the stationary part, that way you need only to reglue the one rather than starting from scratch.

Hi Noel,

Both at close and infinity, with small subjects at the center, when I move the camera to make the subject move to the top of the center of yellow patch, it moves slightly to the right, and vice versa.

But this displacement doesn't affect the sharpness of the subject, therefore it doesn't involve different focusing.

And above all, by adjusting the eye piece to my overall range finding calibration, I have obtained better sharpness within the yellow patch.

Cheers,
Ruben

I think we have failed to communicate you could have glued on a lens to the rear of the view finder to achieve a clearer image, moving the eyepiece is a similar technique.

But you should not have had a vertical movement unless the rangefinder prism is skewed, you dont seem to what to fix this which is good because it is difficult.

You should not have a displacement as in the previous post either.
