In terms of "brickness" we really have to compare the physical focal length & speed, not the equivalent one.

Aaaah, suddenly we do and the holy equivalence is less important? I still don't get what's the problem, it's 200 gram lighter than the Nikon?

And I was talking about the size of the foot of the tripod mount, not about the ring or something.

Yes, I was also surprised about that short foot, but with an Arca plate it does quite week and is less flimsy than the Nikon stuff. What annoys me with this lens is the OIS (or aperture?) motor which is just constantly running. And what annoys me as well is that I need 10 minutes to post something on an iPad. On iOS PZ still sucks.
