Patent: Tamron 10-24 f/3.5-4.5 VC

The optical  formula patents keep on coming from Tamron ahead of multiple Photokina announcements next month. This time it’s a 10-24mm f/3.5-4.5 for APS-C sized sensors.

Patent Publication No. 2016-126280

  • Published 2016.7.11
  • Filing date 2015.1.8
  • f 10.303 15.199 23.483
  • FNO = 3.6 -. 4.1 – 4.6
  • 2ω = 111.70 – 86.59 – 62.07

It’s looking like a busy fall for Tamron, and we’re hoping for the same from Sigma.
