Tamron 13mm F1.8 Di III-A Patent Found

Asobinet found a patent for the Tamron 13mm F1.8 Di III-A, which could be one of the five lenses Tamron plans to announce this year. We have seen a lot of great wide lenses for APS-C lately, and it will be interesting to see how it compares if Tamron decided to produce this lens for X-mount.
