OM System 100-400mm f/5-6.3 IS II Hands-on Testing

We recently received the newly updated OM System 100-400mm f/5-6.3 IS II lens to test from our friends at B&H Photo. We both like the original version of this lens, as it’s a lightweight (3lb) 200-800mm equivalent on micro 4/3 format cameras.

New features of the updated lens include:

  • Better weather-sealing (IPX1 rated)
  • Fluorine-coated front element
  • Improved image stabilization
  • SYNC-IS compatible with 5-axis stabilization up to 7-stops
  • New lens collar

We both own the original version of this lens, so tune in to hear our thoughts about how the new one compares, and whether it’s worth upgrading.
