Panasonic LUMIX G X VARIO PZ 14-42mm f/3.5-5.6 ASPH. POWER O.I.S. Lens

introduction

this amazing lens is the smallest 3x zoom lens for large sensor cameras currently available
not only is it the size of a pancake lens but it's optical quality is as good as most kit zoom lenses, plus you get optical image stabilisation and power zoom as well.
thus what you are paying all that extra money for is the compact size, but that may well be worth it for many people.
Panasonic is bundling this lens with the Panasonic GX-1 enthusiasts compact Micro Four Thirds system camera to make this kit the smallest 3x zoom kit available, even smaller than the Nikon 1 system
best image quality is at 25mm at f/5.6-f/8
Olympus users may need post-processing to reduce CA

ephotozine.com review:
- “Best performance came in at around f/8. Focusing speed and accuracy are excellent, even in low light conditions.”
- “if you use the lens on an Olympus camera, CA will show at wide apertures and angles and you will need to remove it manually”
- “On a Panasonic GF or Olympus Pen, this lens enables you to carry the camera in a large pocket or, more elegantly for a woman, in her handbag”
SLRgrea.com review:
- “remarkably sharp, and a noticeable improvement over the existing 14-42mm kit len”
- “best at 25mm, at 42mm, we note a bit more corner softness when used wide open but improves stopped down”
- “zero distortion at 25mm but minor distortion at other focal lengths”
- “very fast autofocus results, motivated by an in-lens electrical motor that's very fast and very quiet”
