As far as I can tell, we have a regional rep but that person's time is pretty much taken up by his bigger clients. The last time I contacted our regional rep several years ago, he very kindly replied to my message but I have yet to meet him. I would imagine the big spenders get a pretty free rein on time slots.
I just asked for an evaluation loan of the 200-400L lens again. I was given a mid-February time slot so I guess they really are short on those units. They've been telling me more are coming so I may get moved up a bit, not!
Retailers seem to be pretty short on full inventory of these lenses as well.
So, for February, my 200-400 lens evaluation will be done in Bosqué del Apache, NM. It's close enough for us to get down and shoot for a few days and, if necessary, ship back out of Albuquerque on the way home to Colorado. I know what I can do there and I've shot enough with other lenses there to allow a decent comparison.
