Boasting the Smallest Size
And Lightest Weight in its Class

Olympus 40-150mm f/4-5.6 Zuiko ED Zoom LensThis Olympus Zuiko digital ED 40-150mm F4.0-5.6 300mm (35mm equivalent) lens in a short 7.2cm body with ED lens elements, ensuring both picture quality and portability. Boasting the smallest size and lightest weight in its class, this cost-efficient 3.8x telephoto lens uses an ED (Extra-low Dispersion) lens element for optimum correction of chromatic aberrations.

Incorporating a circular aperture diaphragm for beautiful defocusing, this lens assures high picture quality throughout the zoom range. It also provides an astonishingly short closest focusing distance of 90cm throughout the zoom range. 


The Olympus 40-150mm f/4-5.6 Zuiko ED Zoom Lens is a compact and lightweight lens for Four Thirds System cameras, but especially useful for use on the ultra-compact E-400 camera. It offers a 3.8x telephoto zoom range, with an equivalent 35mm focal length of 80-300mm. This makes it ideal as the add-on lens to the standard 14-42mm lens, perfect for portrait to sport shooting.

The lens features 12 elements in 9 groups, including an ED lens element for optimum correction of chromatic aberrations. It offers a close focusing distance of just 3'.

7-blade circular aperture diaphragm produces pleasing defocused effects.

This does not take pictures like $30,000 glass does, but then it isn't $30,000. It's about the same physical size as the shorter kit lens, and takes very similar pictures at its widest zoom as the other kit lens does at its narrowest - the wider kit lens may have very slightly more vivid colors when put side by side, but the difference is pretty subtle.

For a low price, though, you can take perfectly good pictures of stuff that is further away, with a much tighter depth of focus, yadda yadda.

Of course, the apperature's maximum open isn't very wide, so in low light conditions it's not ideal, but I took, for instance, a bunch of great pictures of street lights in fog, and the things they were illuminating. So unless you want pictures of fast moving things in low light, you're probably fine even there. v In THAT case, you either need to turn a light on, spend a bit of money on a flash, a diffuser, and perhaps a flash extension cord.... or spend a whole lot more money on much more expensive glass.
