I have this nice Konica Auto S3 that I bought for peanuts during the "analog panic" circa 2005-2010. On a separate occasion I found a Konica Auto Up 3, like new in box, i.e. a one diopter lens plus some corrective optics in front of main+RF windows.
Only today did I have the curiosity to mount the latter onto the former. See pics below. iPhone pictures with the lens approx level with the AutoS3's top plate.


Clearly the corrective optics is not in front of the v/f windows. Did I make a mistake? Back to the small user manual included in the box: clearly intended for the AutoS3 or the C35FD (same camera, same 38/1.8 lens except silver top and targeted at Japan home market). A little picture even shows what to expect in the viewfinder, with the frame of the Auto Up obstructing the view... at least the rangefinder patch is preserved!!

So : what were the Konica engineers thinking?
Just to save some bandpass : no confusion with the C35 (plain) whose barrel diameter is smaller.
