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.

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 µ4/3 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 ƒ/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 µ4/3 Super 16 digital film camera.

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.

At ƒ/5.6 only?  Well, that's rough...
