The Nokton 25mm f/0.95 Type II is an aspherical lens with a Micro Four Thirds (MFT) mount. It's a manual focusing lens (no electronic interface) with an extraordinarily large aperture allowing for a shorter depth of field.
When Using Panasonic Cameras: Set "shoot w/o lens" to "on" and the focusing mode to "mf".
When Using Olympus Cameras: When using the lens on Olumpus E-P1, E-P2, and E-PL1, set the exposure mode to "center-weighted metering" or "spot metering." Proper exposure may not be achieved if setting is set at "digital ESP metering."
