Tamron keeps patenting designs for Full Frame mirrorless system cameras (aka Sony FE). Egami spotted a new 60mm f/2.8 FE lens design patent. The recent months Tamron published five FE lens designs:
28mm f/2.8
28-70mm f/3.5-5.6
28-320mm f/3.5-6.3
50mm f/2.8
60mm f/2.8
It’s not clear if Tamron planes to introduce these lenses with their own name or if they will sell the design to Sony or Zeiss.
