Just received this lens and it is quite a hefty chunk of glass! Mounted it on my Z7 via the FTZ to take some test shots in the house, and I am impressed. Looking forward to shooting it more once the light improves. The weight of the combo (trio) reminds me of my days shooting with the D700 and several of the 2.8 lenses. And here I thought that mirrorless was going to be light.
