Hello, has anyone any idea why are the original spare spirit level so expensive (77$ each)?

Warm thanks to everybody for the support and the suggestions.

Thank you so much, it´s a very precise example.

Thanks for the suggestion. Actually I had to tilt the lens standard toward the tower in order to increase DOF. But I didn't notice any change in the geometry, overall.

Really thanks for such detailed and precious info.

I see. So this will happen regardless of using a aspherical lens specifically designed to avoid such distortions?
I had no idea, thank you.
