Roger Cicala from lensrentals did test the Sony 20mm f1.8 on their optical bench, which tests lenses *without* a camera: https://www.lensrentals.com/blog/2021/02/sony-fe-20mm-f1-8-g-optical-tests/
This means there is no software correction at play in their findings.

Where do you get that "another league" from? Just from the Pentax PR blurb?
No, the Sony does not rely on software corrections, just like any/all wide angle lens, just like this Pentax will show, even at f5.6. Perhaps the Sony will show a bit more just because the optics are closer to the sensor, but that has nothing to do with the lens and its quality (just with the sensor and the angle the light hits the mirco lenses).
Why is a lens with more elements "much easier to make"? Because it is a stop faster?
And where is the mirror in that Pentax lens, by the way?
Why is it about you paying money, according to you?
Questions, questions, questions....
You're thoroughly incoherent. How did I dare, to attack Sony's supremacy! (weren't you a Canon user?)
- no, other brands don't automatically beat Pentax' rendering. A Pentax lens specifically designed with this in mind can actually be superior in this area.
- yes, the Sony does rely on software corrections; as proven by this site's review. To say otherwise is lying.
- obvious strawman, or unable to comprehend? I clearly said, mirrorless lens relying on software corrections.
- utter lack of knowledge, or trolling? Obviously, the mirrors are in the camera, and that means the lens must have a longer register distance - which means a more complex, retrofocus design if you're making a wide angle.
I am making fun of you, and not bashing. Poking fun is not bashing.
Your attack on this Sony (and Nikkor) only illustrates your total lack of objectivity. I acknowledge the awesomeness of the Sony 20mm f1.8, even if I do not want a Sony camera.
This particular Sony renders really well for 20mm. Yet you bash it, and claim the Pentax is "special" even though not even a single sample image has been published.
The Sony lens will be retro focus too, at 20mm with all these elements. Talking about utter lack of knowledge... Projecting again?
