Proportion of 35mm SLR cameras with WLF compared to pentaprism? 1 to 1000 maybe?
The problem, as TTL metering became adopted as de facto in 135 SLRs starting in the late 1960s, was the fact that most TTL meters (with exception of the Topcon Super D) make waist level finders in SLRs disabling of the camera's metering capabilities! So I would say that after the Topcon RE was launched in 1963, waist level finders in 135 SLRs very rapidly vanished in availability. Even Nikon adopted the integrated prism housing.
The Nikon F and the Topcon Super D had WLF, but the Nikon lost its metering capability without the Photomic T finder. The ratio I guestimate is closer to 1:500,000, and closer to Infinity in the days of dSLR. I doubt there is ANY dSLR with a waist level finder for many reasons.
