First a disclaimer: I have no financial or personal interest in this lens, this is just to share the information.
I have never seen a new 30mm 2.8 lens offered before, this is an unusual opportunity for someone who is a collector, plans to get a FF, or has a need for a NOS lens. It's pricey at about 3 times market price for a used lens, but if this is what you want, it's the only game in town. I have one, not new ;-) and it's a fine lens. It's worth a look for future reference. The case, BTW, is getting to be hard to find, most used lenses don't seem to have one.
