There are 3 basic mods one can make to the EC:

1) shift the lens closer to the film plane so as to shift the point of sharpest
focus farther away than Minox set it. For example, move the focus point from 2
meters (the hyperfocal distance) to 3 or 4 meters in order to get a sharper
image at infinity.

2) shift the lens farther away from the film plane in order to make a dedicated
document copier; one might set it for the distance needed to copy one or two
standard 8.5 x 11" pages and then fix a measuring chain to the loop on the EC.

3) pull the waterhouse stop and let the lens be the f/3.5 again. One ought to
couple this with a shift in focus distance to the hyperfocal distance for the
larger f-stop. About 4m (12'), same as on Minoxes which focus.

I wouldn't begin to know how to disassemble an EC and wouldn't have the
precision tools needed to reset the lens. Don Goldberg has the knowledge and
the setup and has made a number of similar modifications for people. Presumably
MPL could too, but I don't know if they will change a camera from factory specs.

My EC is with Don now and due back in about another 10 days.
