35mm used to be considered wide angle 
.
Contax G does not even have those focal lengths btw. It has 28/35/45/90mm primes and a 35-70mm zoom that you can use with the built in viewfinder and a 16mm and a 21mm that you can use with an external finder. No duplicate lenses with different apertures, no cheap alternatives, nothing. All lenses are Zeiss, everything is made in Japan except for the 16mm, which is really made by Zeiss in Germany. Now marketing and customer base demands each system to have four 50mm prime lenses in each system and at least seven zooms covering that focal length. That's without even going third party.
Btw, if you get every one of those prime lenses, they weigh less than 1.2kg in total and they have AF. Pretty hard to beat by any system in production today.
