Laowa 9mm F2.8
Venus Optics is already taking pre-orders on Laowa 9mm F2.8 Zero-D since a few days now. The first 100 people buying this lens via Venus Optics will get a set of 49mm filters (ND 1000 + CPL +UV ) for free.
Now you can find the lens also at BHphoto here, Adorama here, and soon at AmazonUS here.
BHphoto expects stock for the end of April, whereas Venus Optics will start delivering starting from early April. I guess Venus Optics will first ship all their pre-orders, and only later on deliver to other stores such as BHphoto. Hence, to get the lens as quickly as possible, we recommend purchasing via Venus Optics here.
