The Biogon 35 have 10 straight blades while the E 24 ZA have only 7 blades curved ones. So I guess, this should be the issue, probably?

From my experience, the sunstars have to do largely with the shape of the aperture iris and the number of blades. Most High End M-mount lenses (are there eve low end ones? Perhaps Voigtlander) have 8-12 aperture blades with unique iris shapes, often curved inwards. That contributes to having little stars on light sources.

In this ever changing world, to freeze it in time is a joy.
