I agree, but that "character" is mainly just nostalgia. Compared with today, most old lenses were extremely poor and were incapable of producing a sharp image at any aperture. The lenses for 5"x4" for example, usually needed to be stopped down to at least f/16. and some were so poor that they produced a specific and valued soft focus portraiture look, i.e., blurred.
We shouldn't be too nostalgic about old cameras either. The "Russian" cameras, actually made in a weapons factory in the Ukraine, were made down to the normal soviet standard, the Infamous Hasselblad copy, the Corfield 66, was made in Ireland, now very valuable becasue very few were sold and they all broke, the most memorable thing about it was the mirror system, which worked (very briefly) on a pulley system and a bit of twine. And there were the British Wray and Reid copies of old Leicas, again very rare and valuable for the same reason. The story at the time was that the factories were given copies of the Leitz blueprints, as part of the war reparations,
but good old British companies couldn't be expected to work to foreign metric measurements, so they converted everything to imperial, and didn't work.
Good point, by my superb Nikon F90 is worth almost nothing on the second-hand market, probably too good and too reliable
