What I don't see is how, with any lens, anyone can use the distance markings as any more than a rough guide of the distance. I have read many times that the point of ininity changes with temperature (and possibly other) variations, so all lenses focus past infinity to allow for some movement in this point. You always need to allow a little extra depth of field if you are using distance scales and for hyperfocal. Then again, I don't like rangefinders either...
