I'm closing in on a 40 f/4 for my 500 C/M.
Opinions on this lens?
Thanks,
Alan.

Which one?
The C version, the FLE version, or the later FLE IF version?

Not sure (seller hasn't stated / not avail 'til the weekend or so)...
Is there one to avoid?

Perhaps the early, C version.
The CF FLE version you are looking at is probably the best of the bunch.
The later Internal Focusing version is sharper, but has quite a bit more
distortion.
Good lenses all, though.

Beautiful, beautiful lens, makes beautiful pics. Almost no distortion.
Not far off from the 38mm Biogon in sharpness and lack of distortion --
and room for a mirrorbox.

That's need a (minor) qualification:
Almost no distortion, for a lens with such a wide angle of view.
Distortion is still present:
- 1% in the C 40 mm lens (good),
- 1.5% in the CF version (a little bit worse),
- and up to 3.5% in the latest, IF version.
The Biogon has about 0.4%
And some popular lenses to compare that to:
- 1.3% produced by the humble 50 mm lens
- just over 1.5% in the 80 mm lens
- the 150 mm lens produces 0.5%
For what "almost no distortion" in the Zeiss/Hasselblad lens line can mean
we have to look at the 100 mm lens:
0.09%. almost 40x less than in the latest 40 mm lens.
