Clean lens, can't get cleaner than that. That all I wanted and played with it.
I have 1.4x teleconverter interchange to my Z cameras and Nikon 1 (2260mm is possible, hehe). Photo taken with 1.4x teleconverter and Z6 on DX setting.
The single best lens I have ever bought. The 10 X Range is incredible. For the camera it is on, my Nikon D5, it never gets taken off. Amazing piece of kit.
