How did you go about readjusting the focus? I replaced the broken eyepiece on a Nizo 6080 but now it is out of focus. Any advice on how to properly adjust it?

Basiacally I did not re-adjust the focus as such - I am trusting the lens assembly itself is ok. What I did adjust is one of the optical elements in the viewfinder. The viewfinder consists of two tubes, one of which protrudes through the chassis of the camera and is where you look. This consists of the final lens element which adjusts in and out when you turn the adjuster, and secondly another element which has the split image in the centre. This element is fixed into a mental tube secured with grub screws. By loosening these the tube can be adjusted in and out and also rotated so that the split image is horizontal.
I know that my accident had knocked this element out as the split image was not horizontal. Therefore I set the lens to infinity and the focal length to 80mm and chose a suitable object over 1000 feet away to focus on. Luckily there was a flag pole. With the grub screws loosened I gently prised the tube inwards and outwards until I was certain it was correct at infinity. You have to be a little bit careful here as if you loosen the wrong grub screws (there are three) the whole eyepiece is loosened.
I then tested the lens at closer settings.
Obviously I am relying on the lens still being OK, and if it is not then I stand the chance that some of my shots may be out of focus.
I will report back when I have had the film returned.
It is a little difficult ro explain this without photographs or diagrams. If you still can not understand, send me your e-mail and I will send some photos showing the operation.
