a thousand dollars is quite a bit of money.
i hate to suggest this, but i will ...
lens baby makes a single cell meniscus lens
with sink strainer apertures. it is basically their
take on one of the most popular portrait lenses
of all time - the rodenstock imagon. it is a glass lens,
and it comes in their new mount system.
you won't spend anywhere near 1000$

i am a big fan of soft focus portraits.
less sharp, less in critical focus allows the viewer
some lee-way in understanding an image.

while some may think soft focus is cheesy
ultrasharp and deep DOF can be just as bad.
its just another tool to work with.

have fun
