Thank you for your messages : ) !!!

It looks like a Bgn condition will run 300 and 500 for a good version.
You mean between 300 USD and 500 USD?

On a medium format camera it will be a good lens.
And on a 35 mm. dSLR?

Used in the 1m range at full aperture it is very soft! Superbly sharp and
contrasty if used at f8 or f11 at wider distance. I found it even better
than my 80/2,8 for that.
At f/4 for a sharply focused half-body or
full body portrait I assume that what one may have in focus will be tack sharp,
and the foreground and background very blurred! (This, I assume again but don't
know for certain, is perhaps regardless of the camera used, either a Hasselblad or
a dSLR).

Thank you again, kind regards,
