I have been watching it off and on, over the last couple of months. Depending on the site - B&H, Adorama, Amazon, Beach, etc. - the price has been all over the place - be it in a pretty narrow band, $599, 596, 579, 569, 559 and I thought that I had come across the 549 price ($50 instant savings) previously. Granted that $50 off providing about an 8% off sale price is better than 0. I was just somewhat expecting something a bit more generous for the holidays, especially with the glass that it is essentially paired with is running a bit over 20% off.
