Re: LX infinity focus adjustment at home?

[Alan Chan]

I did it once, unfortunately I had no choice. Since you do not want to mess 
with the pentaprism or screen (you can't anyway w/o the proper skill and 
insturments), the only thing you can do is to adjust the mirror rest arm 
underneatn the mirror (near the DOF preview arm). It was held by 2 cross 
point screws. The diffculty is to reach these screws w/o leaving any marks, 
and you need a long blade for the job (a short screwdriver will wear the 
slot due to the odd angle). Adjust the resting position of the mirror until 
the "middle" (using split image screen) reach just infinity with wide angle 
lenses like 24mm (telephoto lenses won't do due to the long travelling 
characteristic). However, there is nothing you can do about the top and 
bottom parts of the mirror. You can only hope everything will work out by 
itself (and should do unless the prism or screen were messed with).

I fixed my own sticky mirror one time by removing the goo that the
stock bumper had turned into and replacing it with a small bit of
neoprene rubber from an old inner tube from my BMW motorcycle.
The focus adjust was kind of finicky, but certainly doable.
The trick is to make certain that the focus is the same at both the
top and bottom of the finder.
Once you are there, the bumper pretty much has to be in the right
position.
