Olympus EZ-4015-2 Zuiko Digital 40-150mm f4 0.0 to 5, 6 Lens

The smallest and lightest * 3.8x zoom lens in its class is housed in einem72 mm small package, equivalent to a 300mm telephoto lens. It is equipped with an ED lens element (Extra Low Dispersion) provided that ensures an optimal correction of chromatic aberrations. The circular aperture provides a beautiful and natural background blur, and the minimum shooting distance of 90cm throughout the zoom range is surprisingly low, so that guaranteed at any zoom position, a high image quality. The small, lightweight and extremely cheap telephoto zoom lens designed specifically for the E-400 and is ideal for portraits and sports action.

I use this lens on the E-420 and sometimes even to the I-30 when it should be easy. As with the "kit lenses" of all manufacturers, it is not as bright as the larger telephoto zoom compact design a great performance. And yet neither Canon, Nikon, there is such a focal length so extremely small: At least here correspond to the angle of a 150mm film camera with 300mm! 

So you can make discreet and from 5-8m distance portraits or wildlife viewing. It should also operate as a macro lens. 

From Olympus cost-performance ratio is, as so often-just managed a top objective.
