imo, they earned every cent of it. Lots of bang for the buck and they aren't riding on "history" or "collectors value" like some of the german lenses.
And yes, I've noticed that the sales of Leica 35 1.4 R summilux have flat lined. Why pay $3500 for the Leica when the Sigma outdoes the Leica on many aspects for $899?
In performance terms It is the same story with the sigma 180mm and the leica 180mm APO.
I could live with german lenses being overpriced because I wouldn't buy them and they are not af them but nikon's price gouging due to being locked into a system is/was getting very old.
