Pen E-P1 firmware updates to improve AF

Firmware updates for both lenses and the Pen E-P1 body aim to improve focus speed

As widely expected, Olympus has released firmware updates to address relatively slow autofocus performance with its Micro Four Thirds Pen E-P1 and the two m.Zuiko lenses launched with the E-P1 back in June.

Although the E-P1 AF issue hasn't generally been considered poor, by comparison Panasonic's Micro Four Thirds lenses and bodies are noticeably more responsive when focusing.

I will be upgrading my Pen E-P1,17mm f/2.8 pancake lens, and the 14-42mm f/3.5-5.6 standard zoom later today and will be reporting on the level of benefit perceived.

Olympus' official inormation refers to the updates as v.1.1 firmware, with the E-P1 update addressing continuous AF, and the lenses getting improved focus speed.

To update your Pen E-P1 and lens, run Olympus Master 2 or Olympus Studio 2 software, ensure your computer is connected to a broadband Internet connection, connect your camera (after fully charging its battery) via USB to the computer, and follow the procedure for updating the body and lens.

If you have updated your camera, let us know if you feel the update has made a difference!
