Bruce Coxley's reviews
9 out of 10 points and recommendedSmooth & easy to operateImage quality is very good after resetting lens with camera.
Distortion is well above average and no correction is needed on horizontal or vertical edges of newspaper pages. Macro setting images are very soft and will not sharpen enough to be useful. All these shots were on tripod and times shutter. IS was turned off. Much improvement needed to get Zuiko quality.reviewed February 26th, 2011
After a long conversation with an Olympus tech rep we found out that the lens needs to be reset with the camera, as both units have firmware. Instructions are to shut off camera, lock and remove lens, re-install lens but do not unlock. Turn on camera. Go to reset in menu and follow instructions. Then you can unlock the lens and use. I did all of the above and the lens works very well.
