Since I don't have much experience with such large aperture lenses, could someone explain this issue a bit more? Is it normal for a lens in this class or it is a drawback of this lens? Will it get better when stopping down?
This has nothing to do with a specific lens.
It has only to do with having been shot with a digital sensor, being nuked by a much larger contrast, than it can swallow, creating this effect.
Only remedy, to ease this effect, is exposing differently (underexposing and bringing the shadows back in post processing) or exposure bracketing and combining exposures in PP.
The use of color negative film would also be a solution, opposed to using a M9.
