I've had a C330 since I bought it new in 1976 or so.
I'm currently using it with a 65mm and 135mm lens set. The standard lens is an 80mm lens.
The newer lenses are black. The older lenses are chrome. Both are good, but the chrome lenses have older coatings, and the Seiko shutters in each lens are harder to get parts for.
Here is a link for a huge amount of information about the system, maintained by Graham Patterson, who posts here on APUG: http://www.gapatterson.com/grahamp
And here is a link to KEH's Mamiya TLR page: http://www.keh.com/Camera/format-Med...de=MT&bco=534&
They have a C330 body with waist-level finder in EX condition for $265.00 USD. They have a selection of lenses as well.
A 135mm lens is a short telephoto. I really like mine.
The 180mm f/4.5 came in a couple different versions - the "Super" version is the most desirable.
As with a couple of other Mamiya TLR lenses, they came with chrome stiffener rings for the filter threads. Those rings are sometimes missing, leaving the filter rings susceptible to damage.
EDIT: this was shot with my C330 and the 135mm lens (IIRC)
