If 89% (may not be the precise figure, browser just crashed and about to go to bed so not reopening the window) of the shots were taken with f/3.5 or slower lenses it makes me wonder how many f/2.8 or faster lenses were available in 1973 or earlier? Anyone born before the 80's or with good lens history have any idea?
The typical supplied normal on all cameras from the low-end Mamiya/Sekor 1000DTL that I owned up through the Nikon F that was the king of the hill at that time was a 50 or 55mm f/1.8. The 1.4 was a commonly available upgrade.
Aaron Sussman didn't write his book about 1973 even if that's when he published it, I don't think. Much of the experience he writes about was from the 50's and 60's. But even in the post-war period, the standard lens on a Leica screw-mount camera was a 2.8, with an f/2 lens being readily available.
Rolleiflexes of the day, however, came in 2.8 or 3.5, with 3.5 being the more affordable (and to some owners, better).
Most consumer rangefinders of the 60's and early 70's had at least a 2.8 lens.
But if the amateur photographers in Sussman's survey (and all he did was report a survey that for all we know may have been conducted in 1947) were probably using either a Rolleiflex, a fixed-lens folder or rangefinder, or a press camera ala Graphic. Only the latter had interchangeable lenses, but most commercial photographers didn't use but one lens. They might have had a Leica, in which case then, as now, additional lenses are prohibitively expensive for most. If the photographers were high-end and were using large-format stuff, then lenses for large format are very much slower to keep the shutters from being too large. For example, I have an 8-1/2" Ilex Paragon (Tessar formula) which is a normal lens for 5x7 format, and it was among the fastest lenses available of its focal length and coverage at f/4.5 in its day. F/6.3 was more common. Despite this, I doubt that the survey Sussman quoted was filled with large-format photographers.
There's a reason why SLR's ended up owning the serious amateur and commercial markets--interchangeable lenses, and the desire to see what the lens sees. During the time of Sussman's experience, however, the SLR was still a toddler, with few in medium format that worked well and even in 35mm amateur-level SLR's were just starting to flourish.
Now that the supplied lens on most cameras right down to the cheapest consumer model is a zoom, I seriously doubt that the survey Sussman quoted would turn out the same today. I do not see photo galleries (where photographs are actually being sold) using the normal lens that much of the time. A lot, yes, but not nearly 87% or whatever.
