Well timed! There's the crazy Otus 55mm and then the Nikkor 58mm, both ridiculously priced lenses and I consider the 50L ridiculous as well. Still, can't tell how much Sigma is asking for this lens, and how much better it becomes over it's previous 50. But surely it will not be much more, 50mm lenses are supposed to be the easiest and cheapest of lenses to manufacture! How it appears to be so difficult to make a decently sharp, relatively CA free 50 with good bokeh.... oh, I guess that is asking too much looking back at those expensive 50s... so, will Sigma deliver instead?
I'm more interested in the other potential lenses, such as a fast 24mm, but it's good for Sigma to return to classic areas and getting the basic and popular lenses out as well
