. . . and my D5200 has arrived. Excellent shipping from DigitalRev and FedEx. Three days, total, from HK to Toronto. The camera checks out fine, uses the EN-EL14 battery, and I've mounted a shiny new Nikkor 18-300 VRII.
I'll be shooting the D5200 on New Year's Day and throughout the rest of the week. I'll post when I get something decent.
