Excellent images, Erik. Thanks for posting all these.
Specifically on this one, it's the first time I see distortion really kicking in.

Yes, you are right, it is certainly not a lens for architectonical subjects. However, the distortion is much less than with my Summilux 50 v2. I've already posted a shot of a brick wall on wich this (actually very minor) distortion is visible.
It would be interesting to compare the lens on this with the aspherical Summilux 50mm. With aspherical lenses the engineers try to solve the optical problem to correct both the distortion and the coma. With non-aspherical lenses that is not possible.

Erik,
I think the asph is pretty much distortion free.
For me, at its price point, the nokton competition is more like the canon 1.4 (same level of distortion I think), or the sonnars with their slightly different deal (no distortion, good bokeh, focus shift)
I got my Nokton for 20% of a used ASPH...

What the distortion tells me is that I will probably use it only for low light, keeping the summicron for the regular stuff.
 
Distortion is difficult to judge in this case because the camera was tilted slightly backwards and also swung a tiny bit to one side. After correcting this with an image editor, a bit of barrel distortion (maybe 1%) remains, but I don't find it objectionable in this shot (the picture attached is roughly corrected for tilt, swing and distortion). You can easily judge the distortion by looking at the red vertical line that used to be straight and is now a bit distorted by the correction process.

Sorry for messing around with your picture, Erik, I didn't want to "improve" your picture or anything (I think it is very nice and beautiful as it is), I just did this to make it easier to judge the distortion question.

Personally, I find that I don't like lenses that distort noticeably, but we have to remember that amount of distortion is always dependent on the object distance. A lens may distort noticeably at short distance but more mildly or not all at larger distance or infinity.

Thank you joeswe, it's like using a view-camera.

What picture editor did you use?

I agree with your opinion on distortion of lenses. I find it remarkable that old lenses like the Summar 50mm, Hektor 50mm and Elmar 50mm have no distortion al all (but lots of other optical faults), but that most modern lenses suffer more or less from it (although they are corrected for the other optical faults). It is as if modern designers accept a certain degree of distortion of their lenses.

Erik.
