As I understand the current situation, Nikon lens prices have grown very high, and Sigma has overtaken them as the #2 lens seller, behind Canon at #1. I too have high expectations for this lens, just based on the earlier model lens. I think the interchangeable lens camera market has shown a real downward trend in unit sales over the past couple of years, and so high-priced lenses are simply NOT what the market will respond to. I think the third-party makers have done a good job of adjusting their suggested retail prices to better reflect a market where sales opportunities are likely to be better with a lower price point than even a few years ago.
