Olympus ED 18-180mm f/3.5-6.3

The Olympus ED 18-180mm f/3.5-6.3 is less wide than some others in its range, with a 36mm film equivalent at the short end, but it has a greater reach at the long end.

This 18-180mm FourThirds lens from Olympus is a pretty compact piece of glass and thanks to the 2x focal length conversion of FourThirds, it has a 35mm focal length equivalent of 36-360mm. This makes it less wide than some others in its range, with a 36mm film equivalent at the short end, though at the long end it does have a greater reach.
It’s got a decent feel, with a chunky, largely-grooved zoom ring and well-sized manual focus ring, too. All-in-all, It’s been well put together and feels reassuring in the hand.
At the 180mm end, the maximum aperture is a lowly f/6.3, so in most cases when hand-holding you’ll need some form of anti-shake. As the Olympus system is in-camera and featured only on some newer models, this will be an issue if you’ve got an older D-SLR.
There are no AF motors featured, so be prepared for some noise when it’s focusing, and during operation. It was also quite slow to lock on, with a tendency for the AF to hunt in low-contrast conditions.
