Tamron continues with the barrage of patents, this time a patent for a 20mm f/2 VC optical formula has been found.

Patent Publication No. 2016-126279 (Google Translated)

  • Published 2016.7.11
  • Filing date 2015.1.8
  • f = 20.60
  • FNo. = 2.05
  • ω = 46.81
  • Ym = 21.633
  • BF 38.2971 – 38.3188
  • Negative ShiboTadashi
  • Rear focus
  • Bofu (part of the first group)

This lens would make a lot of sense when you consider Tamron’s recent prime lens releases such as the VC, the 35 f/1.8 VC, 45 f/1.8 VC and the superb 85 f/1.8 VC.
