Tamron also designed the Zeiss Batis 18mm lens?
Egami spotted a Tamron lens design patent. Teh design and the specs are exactly the ones of the Zeiss Batis 18mm f/2. 8 lens. So it looks like Tamron designed that Zeiss lens too (yes also may other Zeiss lenses have a Tamron design). sonyalpharumors.com »
