What's this? This is based almost entirely on the lens¿s image quality, based on tests of sharpness (modulation transfer function), geometric distortion, reflexes within the lens (flare), veiling glare index, vignetting, and macro performance. Ease of use was also considered.

Summary:This model has been tested by our experts.
The Olympus Zuiko Digital 40-150mm f4-5.6 is part of the SLR lens
test program at Consumer Reports. In our lab tests, SLR lens
models like the Zuiko Digital 40-150mm f4-5.6 are rated on multiple criteria, such as those listed below.
Image quality:
Image quality is based on tests of sharpness (modulation transfer function), geometric distortion, reflexes within the lens (flare), veiling glare index, vignetting, and macro performance.
Modulation transfer function:
This is a measure of lens performance and shows how well a lens reproduces object detail in the image it produces.
Geometric distortion:
All lenses have degrees of geometric distortion, which will depict straight lines as slightly curved. Two most common types are barrel distortion and pin-cushion distortion. These types of distortions are often seen in zoom lenses at both ends of the zoom range.
About This Brand
Until 2002, Olympus sold film-based, 35-mm SLR cameras under the Olympus OM system. The company currently sells digital SLRs, which use the Four Thirds sensor system, under its E-series line of DSLRs, and lenses under the Zuiko Digital label. It is also developing cameras and lenses using the new Micro Four Thirds system. Olympus currently has more than 20 Zuiko Digital lenses in varying focal lengths that it splits into three classes: super high grade, high grade, and standard. Old Olympus film-camera lenses can be used with the Four Thirds system using an adapter ring.

Zoom ratio The zoom ratio is expressed by a value such as 2x or 3x, and describes the relationship between the longest and shortest focal lengths. For example, a 3x optical zoom with a minimum focal length of 18mm would have a maximum focal length of 54mm.

Weakness
Maybe not as sharp as the old 40-150mm, but still optically very good for the size and price point.
Many will receive this lens as part of an Oly kit, for which they should be very thankful. I already had the 50-200 f2.8, but bought this lens alone just to improve my portability factor. As kit lenses go, Oly's are quite probably the best. This lens capitalizes on the ability of the 4/3 system to go smaller without compromising quality. While it is not on par with the 50-200, it makes a more than adequate substitute when I just really want to travel light. I only wish it were a stop faster, but that would most definitely have consequences on the size (and price!!)
VERY small and lightweight ? good overall optical performance ? nice contrast
Weakness
Corner sharpness at 150mm FL ? small minimum aperture range (price to pay for compact size)
I bought this lens because, despite its very small size, it was reported to perform as good or better than its larger sibling/predecessor, which I also own and have reviewed for this site. Long story short, my copy of the 40-150 f/3.5-4.5 performs a bit better, overall, than my copy of this newer lens. That's not to say that I don't like the new lens, as I actually do like it, and in real world shooting situations, one would likely not be able to tell much of a difference between the two lenses. The issue I have with the new ZD 40-150 zoom lens is that it exhibits a pretty significant drop-off in corner sharpness at the 150mm focal length, which is not eliminated by stopping the lens down to f/8. That being said, the incredibly compact size of this lens, IMO, more than compensates for this relatively modest shortcoming. If you already own the 40-150 f/3.5-4.5 zoom lens or are considering purchasing one, this newer lens is definitely not improved with respect to optical performance, so if that's your top priority, I recommend that you purchase the older version of the lens while they're still available.
