Major kudos to His Mooseness for performing the experiment!!    Perhaps he 
should cross post on the alt lens forum on FM where many of the c/y lens users 
live. 

I think the subject perhaps should  have been larger and more items at 
intermediate distance to enhance the 3D effect.  Mid apertures at mid-distances 
seem to be key, which was done.  The lens has a significant amount of field 
curvature which seems to be a plus for the 3D effect as it  can be negated by 
aspheric elements with flat field.  

In any event the lens clearly has more microcontrast and is a competent 
landscape lens today even on high megapickel sensors.  The macro mode on it is 
convenient but not the main attraction of the lens. 
I first purchased it with my OM 5DII and it obliterated the "L" Canyon 24-105 
for landscapes. I think one can PP many of its qualities in but it is usually 
superior to have them intrinsic to the lens.

A few decent images from the c/y 35-70  in this thread:

I think it is less compelling to purchase the lens in 2020, but it remains no 
slouch.  Fred on FM posted comprehensive crops comparing it to the GM 24-70  
and it held its own with Greater microcontrast at mid apertures and
for reasons unclear to me  seemed to suffer less diffraction softening at F11. 
A remarkable performance for a lens of its vintage. The MTF at 35mm is slightly 
less stellar, but good enough for most purposes and the micro-contrast and nice 
rendering remain.

May the IG continue to inspect, Mike
