Olympus 14-150mm ƒ/4-5.6 ED M.Zuiko Digital was announced last year (2009) in November as an all-in-one ”vacation lens” for the PEN digital cameras. It is designed specifically for the micro-four-thirds camera format and delivers an effective field of view of 28-300mm on such cameras.

This versatile lens offers high-power 10.7x zoom. It is a perfect companion for those who want to shoot wide-scenes, portraits and subjects at a distance without carrying around several lenses.

The lens is optimized for movie shooting with low focusing noise. It is said to be extremely fast high-speed contrast AF. It also features 0.50m / 1.64 ft. closest focusing distance and 0.24x / 1:4.2 magnification ratio.

The 14-150mm ƒ/4-5.6 ED models’ optical construction combines 15 elements in 11 groups. There’re 2 aspherical and 2 ED (Extra Dispersion) glass elements among them to minimize various types of aberrations. All lens elements are also multi-coated to resist ghost and flare.

The lens uses internal focusing method, so it is convenient to use various filters with it. It takes 58mm filters and is also compatible with the LH-61C Lens Hood available separately. The lens measures only 83mm in length and sells at around $700.

This is a very good lens, not the sharpest but certainly very good for a superzoom. It shows some high chromatic aberration at certain focal lengths, but for the wide range of focal lengths the lens offers, it’s probably a small price to pay.

What’s new: The lens was reviewed by SLRgear!

The Olympus M. Zuiko Digital ED 9-18mm F4-5.6 belongs to the company’s line-up of Micro Four Thirds system lenses. It is a wide-angle zoom lens, and delivers 18-36mm focal length equivalent and a superb 100-60-degree angle of view. It was announced back in November 2009.

As Micro Four Thirds digital cameras are compact in size (if compared to Four thirds DSLR-s), they need a compact lens to match their designs. So, this lens, as well as Olympus 14-42mm kit lens, is small and measures only 2.2″ x 1.9″ (57 x 50 mm) when retracted.

As to its optical construction, the 9-18mm F4-5.6 combines 12 elements in 8 groups and includes two dual-surface aspheric elements, as well as Extraordinary Dispersion (ED) and High Refractive (HR) glass elements to help minimize chromatic aberration.

The lens feature 0.1x maximum magnification and 0.25m minimum focusing distance. Its 7 diaphragm blades close to a rounded aperture.

The Micro Motor drives autofocus in the lens providing for near-silent autofocus operation, which is handy in movie recording. There are internal focusing and zoom systems in the lens, so you can enjoy the convenient usage of 52mm filters and polarizers.

The lens’s Micro Four Thirds mount means that it can be used with both Olympus and Panasonic Micro 4/3 cameras.

Dpreview.com:
The lens is exceptionally small and lightweight and delivers very good image quality with almost no vignetting, as well as fast and practically silent autofocus. Though, it produces relatively high chromatic aberration and some amount of corner softness when wide open.

Slrgear.com:
For its size, the lens provides impressive performance. While there are other lenses which provide similar or better performance, none can offer its diminutive size and storage functionality.

The Olympus 50-200mm f/2.8 - f/3.5 Zuiko Digital Zoom Lens is a high-power telephoto zoom lens with a focal length equivalent to 100 to 400mm. It is developed for digital capture with smart technology and is compatible with the cameras that use 4/3-type image sensor.

As to its optical design, the lens consists of 16 elements in 15 groups, with three Extraordinary Dispersion glass elements that help minimize color inaccuracy, chromatic aberration and fringing. The lens also features the SWD (Supersonic Wave Drive) autofocusing system, which translates into a relatively quiet and quick autofocus.

As the manufacturer describes their product, it delivers bright, sharp and distortion-free images with rich, accurate colors, fine contrasts even at the edges. It is claimed to be splash-proof.

Close-up shooting capability is also superb, with a minimum shooting distance of just 1.2 meters throughout the zoom range.

A zoom ring on the lens offers traditional dial zooming. Zoom operation does not rotate the front element, so it opens the way to the usage of the 67mm filters.

Overall, the lens performed well enough. But its autofocus a little slow and its hood seems a little fragile for class of lens.
