Summary: Love these kits, they're great for building an array of lenses when you're an amateur and don't have the big bucks to spend. My only complaint and the reason for only 4 stars is customer service. I wrote them that I was missing one of the 3 lens filters that was supposed to be included and asked if they could send it separately. No response.
Summary: Probably should've gotten the model with image stabilization considering the focal length but for daytime shooting this thing is great. It's also fairly well designed to pull focus on if shooting video. So whether you're snagging images of wild life or shooting close ups for a movie, this lens for the money is fantastic. If you've got $1,700 to burn by all means get the 70-200mm L Series. But if not, this one does a vey good job.
I am pleased with the overall performance of this lens.

Summary: Very good lens for the cost. I have use this lens and have been very pleased with the performance and quality. I consider myself a novice at photography so some of my challenges may be a result of that. I bought this lens to get close up photos of family events and vacations. One challenge I have noticed is that the closer you zoom this lens in if you do not have the camera on a tripod to keep it steady then the pictures may be out of focus or blurry.
Nice Lens, only issue is that it is sensitive to camera shake.

Summary: This is a very nice telephoto lens. I have not had any problems with the autofocus or the operation of the lens. The only thing that keeps me from giving it a 5/5 is that to really use the full telephoto capabilities, you need to use a tripod due to very sensitive camera shake. I would recommend this lens to my friends!
