hmm, mine cron was quite respectable across the frame at f/2, though better at mid distance than infinity. at 20 ft or closer i wouldn't hesitate to put the subject anyplace except the extreme corner wide open. the 50 cron is better though, as it should be with the longer focal length. there is a bit of sombrero like field curvature that makes focusing off center difficult with a rangefinder...
here's my mid distance full sized sample i've shown a lot:
f/2 mid distance
and an off center portrait full sized sample:

Those are pretty shots but nothing to see the edges. Very nice old school just like mine, which is LN condition. Let's see an infinity test though:

That's on the stock A7, your camera, I think.
F2 is certainly very usable, desired in fact for a nice dreamy look. You could take it as an advantage and to be honest this is the best small M lens wider than 50 I ever saw on the A7 cameras, excepting the big ones like CV 35/1.2.
At F2 on the M9:

I'd expect it is better yet on film in the outer zones.
The CV 35/1.4 is about the same price, also small, but is not as even across the frame with a stock A7 and F/2 is not great outside the center: there are some serious waves, though by F/8 it is also pretty good. At F/11 the CV may actually be stronger than the 40/2 on the stock Sony or Leica, but with more distortion.
But if I had to pick one tiny lens to put on a A7, it would be the 50 cron v4, which all the Sonys seem to love and is great on M also. Certainly personal taste, FL, money in the wallet, and even weight (125 gram vs 197 gram) might trump the power Mandler's Cron brings to the table. But for value at 900 bucks it's arguably more a steal than the rokkor. I love the render myself at faster speeds.

The 40/2 is not going to get remotely close to the plain 50 summicron's numbers above, and very few lenses today can.
But in honor of this thread, I put the M-rokkor 40/2 on my M9 today and took a picture:

I think the M9 likes it fine, older coatings or not
I better keep both crons
