The question about IQ difference between the 85 L and the 85 SSC is asked from time to time.
So far, I could see only one direct comparison, made by FM member Dim.ka and linked somwhere in this thread.
Here is one more, since I could not resist on an ebay deal.
I have them both converted and took them out today for some side-by-side shots on a shaved 5D mark 1.
It has been a sunny and nice day, just not for the main subject of the shots (I ate it afterwards).
The following pictures are crops from camera-jpegs and resized, but not sharpened or otherwise processed. The focus is spot on the sticker on the pear.
I tried to show the center sharpness, color, and some background blur.
I made a huge number of pictures by bracketing the exposure and also the focus.
Here are close to equal shots, at least in my belief.
First, the lenses:
85L @ f/2
85SSC @ f/2
85L @ f/4
85SSC @ f/4
I also took the Tamron SP 90mm f/2.5 Macro with me, which is a very good competitor at f/4:
And finally, for those who are interested, the two Canon lenses wide open:
85L @ f/1.2
85SSC @ f/1.2
In terms of image quality, I can not see a big difference in these shots.
( I don't claim that this test is representative. )
What I know: it is lovely to work with these lenses!
