Ok, i'w been tweaking my kalart rangefinder, for 3 days now.. i was wondering, does anybody know how to calibrate the mirror prism to it's right position?
I know the basics, how to calibrate.. but i can't find any information on the mirror prism adjustment! I just can't get it to track the whole distance correctly, either it's ok on close distances but infinity is off, or the other-way around. I'm starting to think the mirror prism might be the solution, because i know how to calibrate everything else.. the arm & front & back slides.
Just to check:
The front slide is for the focal length and the back slide is for fine adjustment? The arm moves the brass thing under the rangefinder, and that needs to be straight when rails are fully racked in.
PS. Ok, it seems I just lucked it out! I went *** the infinity, and just concentrated on getting it right at close distances, well after i got it working on 1.2m and at about 10m.. I though, well.. lets see how far of the infinity is.. and damn, it was dead on!
But if somebody knows how the mirror prism is calibrated correctly, i would be interested to know.. so the next time i have to do this, i would know what the heck i'm actually doing.
