Nikon makes contact
Nikon public relations made contact with me regarding both Nikon Capture NX2 (see prior comments) and D3x sensor/lens mount alignment tolerances, which concern me based on seeing how two D3x bodies perform with both the Nikon and Zeiss wide angle offerings.
I’ll be sending my D3x in for a health check and so the ZF 21/2.8 Distagon will see some “Canon time” which is how I’ve shot the ZF line extensively in the past.
