Yes, it's hard
Yes, it's not cheap
Yes, and you always hear a slight noise (probably stabilizing)
but
the feel and especially the picture quality is very good.
Had not the opportunity to test by the bad weather this weekend unfortunately much, but my first test images showed it is true that this lens already at full aperture into the corners is sharp.
The enthusiasm of the previous tester was therefore justified.
But the lens also proves what many system camera owners do not want to admit: The size of a lens depends mainly on the sensor size and the light intensity. Since I can so squeeze a large sensor in even a small case, I want some objective quality I have just suddenly hang such a huge Trumm front.
I run the 50-140 at an X-E2, because the handling is not so great. I have therefore the Fuji ordered me extra grip, let's see if it gets better so.
Will report again after a few quiet days of testing.
