Olympus ZD 12-60mm f/2.8-4.0 SWD zoom lens

introduction

one of the 1st SWD AF lenses for Olympus Four Thirds dSLR system
perhaps the BEST standard zoom for Four Thirds (and perhaps better than available for any dSLR) giving versatility and AF speed, a 5x zoom while still retaining excellent resolution comparable to the Olympus ZD 11-22mm f/2.8-3.5 wide angle zoom lens and Olympus ZD 14-54mm f/2.8-3.5 II zoom lens at the expense of a little more barrel distortion at the wide end.
some complex distortion at wide angle (thus if doing architecture, consider the Olympus ZD 11-22mm f/2.8-3.5 wide angle zoom lens instead) but overall a superb lens.
would combine very well with:
- Olympus ZD 7-14mm f/4 lens, Olympus ZD 50mm f/2.0 macro lens & Olympus ZD 50-200mm f/2.8-3.5 lens - a total of 4 lenses that give excellent quality and a focal range of 14-400mm in 35mm terms plus a macro/portrait lens.
AF fault identified in those with serial numbers between 230005416 and 230010688 - see free inspection & repair
