Sigma 50-200mm F4-5.6 DC OS HSM

I had this lens on my D5000. It's good value for its price, as it's cheaper than the toyish Nikon 55-200mm, has a metal mount and similar picture quality. The OS works very well, but it's also needed as the lens has poor resolution wide open. It gets better by f7.1-f8, and again worse at f11 and below. A good entry level lens as long as you're not expecting the world from it.

The Sigma 50-200mm f:4-5.6 DC OS HSM only plus is its size and weight, and a very effective image stabilization system, but as for image quality it lacks pretty much at anything below f:8. And don't take it too much above f:11, or it will suffer from diffraction. Is a basic short to mid tele lens, that will render decent images when used properly, but don't expect too much from it. It includes the lens hood which is also nice. In short, you can expect quality similar to a kit lens. Pros: - Size ...
