To be more specific, Yes I did finally replace my nex3n with a nex3n
(familiar is good, but I still want a viewfinder ^.^).  I am
scanning/duping negs to digital - and mostly with the APS-c nex.  so the
50/3.5 should work for me except for the extra adapters needed to link into
the vivtar bellows I currently have.  Currently the camera to lens distance
with bellows fully collapsed is too long.

I have the om macro 80mm on it's way to complete the current project.  But
am in conversation to switch over to an OM bellows, which may allow me to
use the macro 50/3.5 on future projects.  (though my 50 got bashed in the
aforementioned fall and might need replacing).
I do enjoy the macro 50/3.5 as an all around shooter, and it sounds like
the 90/2.5 is also a nice all around shooter so I am in conversation to
pick that up as well.

What is the eSIF?
Also I would like to locate a roll film attachment for the OM bellows:

thanks again,

You came to some different conclusions than I from the brief ". . .dupe
some negs . . ." Dupe", together with the tag to
his posts "shoot film ", led me to assume the aim was to create duplicates
on 35 mm film. Looking back at his posts, I
see that he was using Sony NEX APS-C, but the camera was broken - so no
clue f it was replaced, or the tool for this
project.

IF it's APS-c or (?)4/3, I agree, the 50/3.5 is excellent at 1:2 or so.

> So I?d go with the 50mm/3.5 lens, and add some fixed extension tubes to
make up the difference, if needed.

Again, we read differently. I read "Camera to Lens distance is too long."
to mean that he couldn't get the lens close
enough, even with bellows fully collapsed, not that he needed more
extension. Needing more than bellows extension for
1:1 with a 50 mm lens seems unlikely.

Yup.

> Be sure to crank the 50 all the way out, as I believe it has a floating
element group that is only engaged when fully extended. (Or was that just
the 50/2 and 90/2 that have that?)

eSIF say "Floating mechanism to compensate for close distance aberrations."
Set to close focus and focus with bellows
extension.

> I?m also a big fan of the Telescoping Extension Tube, which occasionally
can be seen on evilBay for $100 or so ? much cheaper than an 80mm macro!
You could use it to extend the Oly bellows, but it is very useful in its
own right. (I call it my ?field-hardened bellows,? having ruined an OM
bellows by throwing it in a pack and breaking off the tiny set screws
poking out of it.)

Yup, great tool. I used to stalk with 135/4.5 on bellows. The TET is much
better in the field.

> BTW: I?ve just converted a Nikon PB-4 bellows to mount micro four thirds
on the back and OM on the front. So I can finally make use of the huge
image circle of the 135/4.5 macro without raiding the secret Wyoming
facility for the prototype OM tilt-shift bellows. Works like a charm! I?ll
be posting about it on mu-43.com.

Sounds like a fun project for a tinkerer with tools I don't have. Trying to
imagine what I would use it for . . .
