No Ultrasonic AFLenses with ultrasonic focusing mechanism tend to be quiter and faster than traditionally focusing lenses. One or more Low Dispersion lens element is usedLow Dispersion lens elements help to reduce chromatic aberration. Not stabilizedImage stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule. Metal mountCheaper lenses are usually equipped with plastic mount, while more expensive, professional lenses have metal mount. In general, metal mounts are more durable, and a good thing to have when lenses are changed a lot. When a camera is used mainly with one lens, the material of the lens mount is not that important. Internal FocusingInternally focusing lenses don't change their size while setting focus. The front lens is fixedThe fixed front lens is not rotating during zoom and/or focusing. This allows the photographer to use petal shaped lens hood. Fixed front lenses also make the use of polarization filters a lot easier. Weather SealedWeather sealed lenses are protected from dust and water. While they are not water proof, these lenses can be used in rain and other humid environments. Some sealings only provide protection against dust or water, not both. Sealing is only available when the lens is used on a similarly weather sealed camera body. No drop-in filter supportDrop-in filters are used in those lenses where either the front lens is too large, or the field of view doesn't permit the use of traditional filters at the front of the lens. Usually bright tele and ultra-wide angle lenses support this filter type. |

High performance with high portability. Wherever you go, from the fields of sport to the wilds of nature to fashion runways, you can be assured of superior image quality, even in low light. Both ED and Super ED lens elements produce outstanding sharpness and color.

Outstanding lens.
Because of the 4:3 systems 2x multiplier, this lens delivers the same reach as the traditional 300mm 2.8 lens on regular cameras. and it is faster by one stop.
This means when a normal camera shoots at 125th sec, this lens give you 1/250th sec.
Sharpness and contrast is outstanding. the lens is half the weight of a similar lens for a Nikon.
This lens have been with me to and allowed me to photograph in low-light when normal lenses just are not fast enough.
HIGHLY recommended for sports, adventure, nature and fashion photography. Its not a small lens, this is for serious users.

It's enough to say this lens is belong to Super High Quality grade from Olympus. The lens is very sharp and sometimes too sharp. hard to PP because of the sharpness so you need to add more sharpness if you resized the photo or just crop 100% and you'll be fine. I have not used this lens with any teleconverter yet but I'll get EC-20 soon.
It's heavy but worth the weight and the money. the contrast and the colors just perfect. fast focus but a version with SWD would be super fast.
I posted a photo, see it yourself.
