Popular Photography Magazine as published their review of the Canon EF-S 18-200mm f/3.5-5.6 Image Stabilized (IS) Zoom Lens:

In the past two years, the 11X IS superzoom has become the ideal general-purpose lens — certainly for shooters whose cameras don’t have on-board shake reduction. This Canon fits the mold. Very light and compact, it’s a gracious and adaptable traveling companion. Impressively sharp, it’s also an obvious choice for handheld low-light pictures, including event and theater work. Its real fortes, however, are close-up macro subjects, distant wildlife, and almost everything in between. Sports? Go for it!

Novoflex premier manufacturer has announced the availability of a new lens adapter to mount Leica M lenses onto the new MicroFourThirds-Standard camera bodies which include the Panasonic Lumix G1, a new Olympus as well as camera bodies that will become available next year using the new MicroFourThirds-Standard system.

This is the sharpest Jupiter photo ever taken. It was snapped from earth with a telescope using special adaptive optics. The new technique, called MAD (for Multi-Conjugate Adaptive Optics Demonstrator), uses two or more guide stars, allowing it to remove blur from a field of view 30 times larger.

Captured using a new computer-assisted process and a 27-foot (8.2-meter) telescope in Chile, the result is sharp enough to show features as small as 180 miles (300 kilometers) across.
Adaptive optics, Marchis said, adjusts for distortions caused by the Earth’s atmosphere, “providing images as if the telescope was in space.”

I have read good comparison blog on photo.net, which is comparing Canon EF 50mm lens F1.4 vs F1.8 MK II, It is really completely nice comparison.
The Canon EF 50mm f/1.8 II is light as a feather, compact and high-performance, standard lens, and has full time manual focus also even autofocus sometimes hunts in low light.
For Canon EF 50mm f/1.4 is sharp, small, light, inexpensive and, fast.

Olympus Zuko has a good optical lens quality, I have no doubt with it.
Even the focus motor which is relatively slow and noisy, and the lack of a focus range limiter switch, I still recommend.
The features of Olympus Zuko 50mm 1:2.0 macro:
• 50mm fixed focal length; fast F2.0 maximum aperture
• Macro focusing: 1:2 maximum magnification (1:1 35mm equivalent)
• ‘Focus by wire’ manual focus system
• Four Thirds mount for Olympus and Panasonic dSLRS
• Price $410

Based on Dpreview, Olympus Zuko 50mm offers a winning combination of optical quality and solid build in a compact package. With its relatively fast maximum aperture, it also offers Four Thirds users the opportunity to use true selective focus effects. Quite simply, every E-system user should own one.
