Firmware update fixes compatibility issue between the Panasonic 100-400mm and the Olympus OM-D E-M1 II

The Panasonic Leica 100-400mm f/4-6.3 is an excellent lens for wildlife photography and is a less expensive and more versatile alternative to the M.Zuiko 300mm f/4 Pro. As such, it is not a surprise that many E-M1 II users have been using this lens on the new flagship camera. However, one bug has been reported multiple times: when the AF Limiter switch on the lens is set to 5m-Infinity rather than FULL, it causes focusing and stabilisation issues.

Panasonic has just released a new firmware for the lens (version 1.1) that does the following:

  • enables compatibility with Dual I.S.2 on select Lumix cameras (note that a firmware on the Panasonic camera will also be required)
  • Fixes the instability of autofocus when the focus switch is set to [5m – ∞] when using the OM-D E-M1 Mark II.

Olympus users can update the lens with the Olympus Digital Camera Updater software. More information is available here.

Panasonic users can download the firmware and follow the instructions here.

Note: keep in mind that the Panasonic 100-400mm is not compatible with certain functions of the E-M1 II such as Sync IS, Focus Stacking and Pro Capture.
