Excellent comparation! Here is my Zuiko 135mm f/2.8 adapted with Speedbooster Ultra on XT1

Still getting used to my first ultra wide angle lens but really love using the 10-24 - such a nice handling lens - if you know what i mean !
One from the Peaks - from Fernilee Reservoir up to Shining Tor and Cats Tor - was a lovely hot April day !

I made a short last week on my last day in Japan.
Shot on my Fuji X-T3 and with a Helios 44-M 58mm f2 lens.
 

The Carl Zeiss Jena lenses give great colors, sharpness and close focusing at very reasonable prices.
The XT2 sensor seems to pair well with this lens.

My two cents: Minolta AF 135 2.8, all shots aprox. f4 with K&F adapter on a X-T10

And for comparison, this is a fujinon XF 60 mm macro. f4DSCF1641 by Manuel Bustos, en Flickr
 
Both lenses are tack sharp. May be the fujinon xf is even sharper... or not, I couldn't really say

Heres one from my SMC 135 f/3.5

Carl Zeiss Jena 135mm f4 with aluminium tube / X-E2
If I remember right it was closed for 1 stop.
 

 

I agree about the Jupiter-11, 135mm f4.  Very compact and sharp lens with a creamy defocus.
