Olympus 14-42 comment by Cliff Smith of TrustedReviews – Cliff:

I haven’t had a chance to try the 17mm f/2.8 lens yet, but the Zuiko 14-42mm f/3.5-5.6 lens is excellent, producing pin-sharp detail from corner to corner at all focal lengths with barely any optical distortion and no trace of chromatic aberration thanks to the use of ED glass. There are two optional adaptors available that allow the E-P1 to use both existing E-system lenses and even OM-system 35mm lenses. As far as I know it should also accept Panasonic G-system lenses.

Olympus E-620 dSLR /14-42mm Hands on Review and Sample Photos at Steve's Digicams – Steve issues the following verdict:

Olympus continues to offer high-quality features and abilities in their E-series models. While the E-620 is what we consider an advanced amateur model, it sports an entry-level price tag of about US$699 or less for the body/14-14mm Zuiko lens outfit. With excellent image quality both indoors and out, pleasing High ISO capabilities, and loads of easy to use features, we have no problem giving the Olympus E-620 dSLR a high recommendation.
