I got the new Nikon 24-70 f/2.8 "VR" version. It is an amazing lens but I had some doubts with this lens zoom ring stiffness which was an issue with the previous version of this lens I wanna know from others who have been using the VR version Do they suffer stiffness with zoom ring? Do they have a bit give while operating the zoom ring I was just curious and went to a Nikon authorized service center and they showed me another lens from the box and it had the same movement and feel for the zoom ring, it was bit heavy to use. Both lenses (mine) and the service center had serial numbers starting from 20xxxx my only curiosity is those who use 24-70 VR do they have the same feeling? or its just me !! Also I would Like to know how tuff is this lens to use what do you think about the build after use.
