 With the latest version of lens firmware
This is something I find appalling from just about everyone. In 2004 I got my E-300 from Olympus, and to upgrade it's firmware or to upgrade the firmware on a lens, you connected your camera to your computer with a USB cable and away you went. Here we are now, 14 years later, and it seems like Oly is still the only player where you can do that. At least the new Sigmas and Tammys can use a dock, but the big question remains WHAT TOOK YOU SO LONG!
