Hasselblad  did not use  tessar.  tesar was  a  good
lens  but certainly
 not the hi end

Incorrect.  There were various, like the *Tele-Tessar*, which appeared for
Hasselblad.

 One of  my all time favorite lenses is the Hasselblad 80mm f/2.8 Planar C
 lens  made by Zeiss.  Even their low-end Tessar lenses are  awesome.
 
 
 Anything made for Hasselblad could hardly be called  'low-end'.  (A bit
 like
 a 'low-end' SGI, there was basically never  such a thing... certainly not
 in
 terms of original cost.)
 The only  truly low-end Carl Zeiss optics are probably the *Pentacon*
 series, made by  the post-WW II Carl Zeiss Jena branch of the GDR.
 Take a look at  the Sony a7 series of bodies, people are using RTS lenses
 on
   them.  You can put almost anything on them, and
they?re a full  frame
 sensor.  I know that the wider lenses might have some  fringing issues at
 the edges. 
 Which (affordable) lens  *doesn't* have imperfect edges, especially
 completely analog lenses without  any in-camera digital correction.  (This
 can also be done afterwards,  if one knows the possible distortion values.)
 The Sony a7-series aren't  exactly cheap.  More affordable and rather good,
 too, are ?4/3  cameras, especially in conjunction with a focal reducer, if
 the crop is too  much of an obstruction.  I gain an extra stop of light, on
 top of  reducing the crop, with my M42/Praktica thread mount lenses.   My
 thorium-coated Asahi Pentax Super-Takumar 1.4/50's maximum diaphragm  is
 effectively widened to an impressive ?/1.  On top of that I have  in-body
 image stabilization, good high ISO handling and other features, all  at the
 fraction of the cost.  On top of that, I can exchange my lenses  with my
 dedicated ?4/3 Super 16 digital film camera.
   I?ve started looking seriously at the a7 series,
as it would allow me 
 to
  use a lot of lenses I have, that I can currently
only use on 35mm  film
 bodies.
 
 Nothing prevents you from using a full  frame lens on a smaller (e.g.
 APS-C)
 sensor body.  The crop isn't  always a negative, sometimes it can change a
 mediocre tele-photo prime into  an excellent one.
  Since I started shooting more than just  Nikon,
it?s a lot harder to find
 Nikon lenses I really like.  The  only AF lens I really like is the 
 Nikkor
  50mm f/1.4G, at f/5.6 it can  compete with my
50mm Summicron.
 
 At ?/5.6 only?  Well,  that's rough...
