More lens news!  However, I'm taking this one with a HUMUNGOUS grain of salt.   Both SigmaRumors and PetaPixel are reporting that Sigma's Otus-killing 50mm lens is going to run for a stunningly inexpensive $790.  If this is true,  I'm placing my order the second it goes on sale.   Rumors are that this lens has completely eschewed trying to compete with Canon and Nikon's 50mm f/1.4 offerings and have gone straight for competing with Sony's $4,000 Otus 55mm f1.4 uberlens.  Early reports from testers are reporting that they have just about hit that mark,  blowing away the competition from Nikon and Canon.  I think the lens wars are about to get really interesting.

Attached below are some rumored sample images from this new lens, comparing it with its current competition:
