Slight correction, and an unwelcome twist...
The Sigma is a 100-300. The lens on the camera is a Tamron (38-80, I think. I forgot to write it down).
After digging through the boxes I have the original boxes for the flash and the battery grip, but not the camera. Also, as I was checking everything I snapped the back closed and the latch broke. grrrrrrr. Now I get to buy a latch plate for it.
*Edit to add* looks like the latch failure is a common problem. Fortunately it's a cheap and easy fix. Parts were $10.50, shipping and all, and all it takes is two screws and a few minutes to replace. I wish everything else today had been that simple and inexpensive. :(
