The PRO in the lens name indicates that the Tele Zoom against dust and water is protected and a sealed metal enclosure has. The fast lens is also available to -10 degrees cold ready for use, provided it is used on a similarly cold Olympus OMD EM safe 1. Facilities include a tripod mount and a lens hood needs to be installed once no longer bought and can be pushed all the way back.
At the small screen, the image section corresponds to a 80-300mm telephoto zoom and at a maximum aperture of f2.8 throughout. To my knowledge there is no other manufacturer has a comparable zoom.
For me, this lens is the horse operation with optimum focal length by eg ridden horses for sale to photograph my workhorse on the tracks, horse riding or driving groups and film. Thus, but the field of application by no means exhausted, it is ideally suited where a strong optical performance is desired or required with light intensity and a variable focal length is also a portrait of optics, at the zoo or wildlife park, sports, for weddings or for any other application areas.
Also, the C-AF (autofocus for continuous shooting) is in conjunction with that Pro lens rapidly and accurately, the photographic results are conclusive in terms of sharpness and appearance. The Bokeh like it very much, even if it is perceived by many photographers as a bit restless. The blur circles are nice and round.
By matching 1.4 teleconverter, which came into the market at the same time, I see no visible deterioration, the converter is very well matched to the Pro-optics. However, the accuracy decreases (eg fog) quite dramatically if the subjects also move more quickly in inclement weather conditions. The converter I will therefore put away for the expected 300 f4 of Olympus.
What bothers me only that you can detach the tripod collar while, but then you have to accept that small Führungsschräubchen upstanding something. Therefore, I have gotten used to it, to lead the camera and lens combination with your left hand under the stand base.
A word on the weight: 880 grams, this lens is still a lightweight in terms of features and performance. In conjunction with the OMD E-M1 has a 1A combination of robust technology and equipment as well as optical performance coupled with very low weight and short length. It's fun so carefree to photograph!
Therefore: strong buy recommendation for advanced amateurs and a must-have for professionals!
