AF-S DX Zoom-Nikkor 18-135mm f/3.5-5.6G IF-ED
I quite like this lens. Given that its a kit lens, the 7.5x range is very nice and the focusing is quick and quiet while the focusing distance of 0.45m and maximum telephoto of 135mm give it decent macro ability. The build quality isn't great, but for a kit lens I think it's acceptable. The manual focusing ring is pretty bad with about 1mm of free play in either direction and its not very smooth either, fortunately, manual focusing is rarely required. I'm quite happy with the sharpness, not so happy with the barrel distortion. Without VR you're quite susceptible to shake towards the telephoto end.

Here's an example of the barrel distortion. 18mm, f/8.0
If you've seen any of the other images I've posted around the forums, they were also taken with this lens.
