It was a nice Fall morning, and I've been wanting to do this comparison for a while. I've bought several uncommon lenses recently, and have the Amotal on loan.

Eight is Enough... I did a lot of lens changing for these two scenes.
List of lenses and their optical configuration:
Summar 5cm F2, 1-2-2-1
Amotal 5cm F2 1-2-2-1
Canon 5cm F2, 1-2-2-1
Minolta 5cm F2, 2-2-2-1
Fujinon 5cm F2, 1-1-1-2-1
Topcon 5cm F2, 1-2-2-1
Summicron Rigid T1, 2-2-2-1
Konica 5cm F1.9, 1-1-1-2-1

All on the M240. I used the EVF for focus, but confirmed the Rangefinder was accurate on all.

The selected scenes. Fence posts, my usual shots for testing calibration and that all the elements are centered. Tripod mounted, and shot at F2 and F4, two sets for most of the lenses. The exception- the Summar, four shots without hood and four with. Conclusion- use a hood on the Summar.
 
I await the test with happy anticipation. I know that it has been done in a scientific manner as that is your mode. And you know just a bit about lenses, so this should be an interesting test.

Thanks for taking the time and making the effort. And as you may have heard, one test is worth a thousand opinions. ;o)
 
Canon 5cm F2, slat test.




This is Canon's first "super-speed" lens, quickly replaced by the 50/1.9, replaced by the Rigid Canon 50/2. Comparison for another day.
Center sharp, but corners are soft.

Amotal Slat test.




The corners are much sharper than the Canon.
