I sort of like both focal lengths. The 35 is nice because it's wide but no so wide as to be obvious.
The 50 is sometimes derided, but it's really a good general-purpose focal length.
A well-designed 50 can cover a lot of territory.
For example, the Carl Zeiss Planar for the Contarex has a close-focus ability that is simply outstanding. The lens' design has served as the basis for nearly all 50mm lenses out of Japan since the 1970s.
It's a decent portrait lens, although not the first choice, and there probably are millions of family photos -- group shots, as well as shots of fathers, mothers, aunts, uncles, grandchildren, dogs, cats, cars, houses and summer vegetable gardens -- taken with a 50mm lens.
The 50mm length (or in that range, give or take 5-8mm) was found on the humblest of cameras, such as the Argus C3 (Cintar), as well as some of the most expensive, Alpa Reflex (Macro Switar).
As a user, I probably have shot with the 50mm lens more than any other focal length, and that's because most cameras that I've bought have that lens attached to it.
