I'm posting this 14 years after the original posts. Looking by his profile, I see Alex has posted only as recently as 2 years ago. I hope he is still with us.
Firstly, it's still a great post and I'm glad he wrote it.
If so, I would like to shame him just a bit for almost totally neglecting fixed lens rangefinders. About them, he only wrote:
There were at that time dandy automatic rangefinder cameras made by all the major Japanese camera companies, colloquially misnamed as “bakachon” or “idiot” cameras. But if you wanted a new professional rangefinder camera, by 1984 you could only choose between a Leica M4-P or M6.
Since cost was a concern, I am a little surprised that he did not more seriously consider some of these "bakachon" cameras. The main weakness to them was that they were mostly only offered with 40 or 45 mm lenses. There WERE a few offered with 35 mm; one of the all-time favorite focal lengths. (and a few with 38 mm...)
Elsewhere in the first couple posts, he said that rangefinders were quieter, but not THAT much quieter. Well, these "bakachon" cameras were/are MUCH quieter, with the leaf shutters, built into the lenses.
Speaking of the lenses, some of there were very high grade; I would say on par with a Leica 35mm. For example, the Yashinon 35/1.8 on the Yashica Electro 35 CC. Or even some of the slower f/2.8s, like then (then-newish) 35/2.8 on the Olympus XA. Let's not forget the excellent Zeiss Tessar and Sonnar on the Rollei 35, which was still in production in the early 80s. (if you could settle for scale focus and a 40 mm lens.)
As a side comment, I was perusing my book on Alfred Eisenstaedt last night. He is often pictured with two cameras around his neck: A Leica rangefinder and a Nikon SLR. I presume the Leica was fitted with a 28 or 35 mm lens, while the Nikon looked to have a 50mm. So even the the pioneer street photographers were not so pure as to avoid SLRs.
