Hi, I have an Oly e-pl1 To speed-up autofocus I've bought a 14-42IIR to replace my first generation ED14-42. It is indeed much faster at focusing, and much more quiet. And smaller. However, I get some very strange out of focus like effects in some parts of the photos. old lens: (ED 14-42) https://dl.dropboxusercontent.com/u/2688195/gammel.JPG new lens: (14-42 IIR) https://dl.dropboxusercontent.com/u/2688195/ny.JPG This is taken at 14mm, Aperture program, 3.5, 1/320, ISO 200, super fine, in my back yard. (yes, I need to move my lawn!) Notice how a grass and bamboo in the right side of the picture is totally unsharp on the new lens. But at least as sharp in othe places. I wonder if this could be due to lens distortion correction in the camera? According to olympus (I called and asked), the new lens should be corrected perfectly even though it's newer than the camera. Did anyone see the same phenomena?
