Good morning;
It is interesting that there are here in stock four out of the six models you listed.
Noting your specification for a fast lens, others have already suggested the addition to the list of the Yashica Lynx-14 in one of its four variants. I tend to agree, although there is also the poiint that it might have difficulty fitting into that "small" category, but it certainly does meet that "fast lens" requirement, and it does have a full range of shutter speeds. I do agree that it is one fine camera that will certainly do the job for you.
The other Yashica 35 Series of cameras are less serious contenders, although they do fit well into that "small" category. I admit that other than the test roll through mine when I got them, other than the Yashica Electro-35, I have not used them much, having the Yashica Lynx-14, Lynx-1000, and Lynx-5000 that I enjoy using more.
The Minolta Hi-Matic 7s II has been a disappointment for me, in spite of so many other people having a cult like adoration for them. To me the 7s II is a smaller stripped down model that is lighter in weight and more difficult to hold still for taking a photograph. One thing that some weight does give to you is inertia, and a easier time holding the camera still. Yes, I know that the 7s II shutter only goes from 1/8 to 1/500 second, and those are the settings that most people will hand hold, but I do have several tripods, so I can use a camera with a full range of shutter speeds. In the Minolta Hi-Matic Number Series, my preference is still for the Minolta Hi-Matic 9, with its full range of shutter speeds from 1 second to 1/500 second, and the choice of Shutter Priority or Aperture Priority, plus a full "Automatic" Mode or what we now call a "Program Mode." Just for reference, yes, I do have working samples of the entire Minolta Hi-Matic Number Series of rangefinder cameras here.
The Canon QL-17 G-III is another camera that is a little bigger and heavier than the Minolta Hi-Matic 7s II, but it also is a little more convenient and stable, and it does have the Canon Quick-Load feature.
All of these cameras do have that nice discreet "snick" of an in-the-lens leaf shutter.
I know that I do not have an Olympus RD, and the Konica S3 sample I have needs repair, so I cannot comment on that one either.
