I cringed when I looked at my 1dx box as it sat on my doorstep after being serviced for the prod advisory (picture below)
there are holes in the box from what appears to be a "blunt force" blow from something. there are 3 or 4 holes that I can literally stick my fingers through right into the box. i estimate that it would take a pretty good blow to do that.
the camera was packed very well, no issues with the internal pack job and the camera looks fine. but still, not what you want to see....probably was fedex fault from careless handling of the box.
ALSO...my shutter click sounds different after the service...a "clunkier" sound as compared to before. it works fine, but sounds different. anybody else notice that?
