Tamrom Patents 10-24mm F3.5-4.5 VC and Tamron 20mm f/2 Di VC Lenses

Tamrom Patents 10-24mm F3.5-4.5 VC and Tamron 20mm f/2 Di VC Lenses

Two new Tamron DSLR Lens patents have been published this week, the first of which depicts a wide-angle zoom lens, the Tamron 10-24mm F3.5-4.5 VC. Tamron already produces the SP AF 10-24mm f / 3.5-4.5 DI II, so it is quite possible that this is an incremental upgrade of that lens, with the addition of onboard Vibration Control:

Patent Publication No. 2016-126280

Example 1

  • f 10.303 15.199 23.483
  • FNO = 3.6 -. 4.1 – 4.6
  • 2ω = 111.70 – 86.59 – 62.07

  • Anti-vibration (third group)

The second patent depicts a 20mm prime lens, which if it makes it to production would become Tamron’s widest prime, the current being the Tamron SP 35mm f/1.8 Di VC USD:
