Who hatt the Olympus kit with two lenses 17,5-45mm and 40-150mm with an aperture of 3.5 or 4.0, will be amazed at 2.0 aperture. I used it mainly for indoor soccer. And there the light was still too low, including because the hall waiting wanted to save money and only half already gave to light, or as I've always said, the players have moved too fast. I then times as shoot a few hundred images, it seems to me not on one or the other blurred image. Have found that it does not work so well with Continue Focus. Then happens that once the entire Focus range is up and down driven. If you consider that I paid 3 years ago for the kit with 300 Euro Camera E420 and two lenses, the lens has beaten quite to book with 730 Euro. But now you realize what the camera can. Just as with a music system. You can have the best system, only if the boxes are good, you can hear what they can. My main point was the intensity and is now there. It is possible to take pictures with 1/320 second.
