Main blog reports that this lens will be announced in three weeks.
Suppose the price is $500. Aside from $500 being a round number, it's somewhat in-between the 28mm 1.8 and the mass-produced 50mm 1.8.
Given that the Sigma 35mm f/1.4 takes an awful lot of beating at $800-$900, but given that this OEM Nikkor will surely be lighter...
--How good will the lens need to be to sell well? --On top of it being good, does it need razzle-dazzle (Nano Coating, super-duper-mega ED, unicorn-hide carrying case, retro styling, insert your own ideas here...)?
