Excerpt: You can focus if subject doesn't move, camera is on a tripod and iView with zooming in on the display is used. Even if zoomed perfectly, this lens is VERY SOFT. Manual focus on moving subjects is difficult. Assure your camera allows entering of custom lenses via the menu, like the D7000, or no metering. Considering the price, an OK lens. But be aware, good results with this lens are hard to achieve.
Pros: Lightweight, Long focal length
Cons: Manual Focus Tricky, No Auto Focus, Poor in Low Light
Excellent quality / price. Recomended for normal light conditions

Summary: Excellent quality / price for a telephoto lens of reduced size and powerful. Although low light, this lens gives very good results in average light conditions and macro photography, supported by the flash.
Summary: I like that this lens give me the opportunity to shoot far away subjects. The lens along with my T1i on the tripod, I still have camera shake or my tripod can't handle it. Haven't gotten a clear picture yet, cause of the camera shake. So I guess I will get a sturdier tripod then see how that does!
Summary: Great lens for a beginner or for who wants a cheap telephoto lens . Picture quality is not as good as Canon lens but i'm really impressed with picture quality for the price I paid for this lens . For the beginner , this lens has to be used with a tripod , almost impossible to use it without it .
