Lightweight and small don't mean poor shots. Caught this eagle in Florida while hanging out at the pool!

Its a good zoom lens, specially for that price of $99

I bought this lens to go with the Olympus Pen EP5 and am so glad I did. I usually shoot with primes but sometimes need a longer zoom when working outdoors with animals. However, I've shot with enough Canon zooms that I didn't have high expectations for a kit zoom like this. The price was excellent so I decided to give it a try, and am very pleased with the results. It shoots fast enough outdoors and zooming is a little tight but reasonably smooth. An 80-300mm lens can be quite big and bulky in the dslr world, so from a dslr user's perspective, this lens is very small and light and has great reach. Even with street shooting it isn't that much to add to the EP5 body that it becomes a distraction. People have mentioned that it's plastic but I don't find that a drawback because the build still feels solid and should hold up well so long as I don't run over it with a car tire. But the real surprise is the image quality. Except for the 70-200mm f2.8s, most longer zooms can be pretty mediocre when it comes to IQ. I find the 40-150 to be a little soft at the long end, but the details are crisp throughout most of the rest of the focal range and the color rendition is very nice. So far I haven't shot in super low light with it, but even indoors it doesn't cause the camera to hunt for the shot. This lens and the Olympus 45mm are becoming my two must-haves for dog parks and agility trials. A no-brainer, really.

I was amazed at the sharpness of this little lens in good light. Extremely lightweight also. I would have liked a metal mount, but for the price it's hard to beat. Matched with the Oly kit lens, you will have nifty kit that your back will thank you for.

For the money this lens costs, you really can't beat it's performance. Absolutely no complaints. Yes, it is very light and very plastic, but what do you expect at this price point? :)
