Excerpt: I bought this product to make it easier to take photos of theatrical productions I am hired to photograph. Instead of constantly changing lenses I wanted one I could get a full stage and a close ups with.
Summary: This was intended to replace my 18-55 and 55-300 Nikon kit lenses (VR models). Unfortunately, the image quality was not on par with those lenses, so I returned this package.

Summary: This is a decent lens given the focal length range and cost. Competing lenses can go for over twice the cost. I really enjoyed this lens but after about 8 months of use the optical stabilizer (OS) developed a whirring noise that was faint but clearly noticeable while using the camera.
Summary: very cheap lens. comes without image stabilizer for sony. works ok with the laea2 adapter. good for every day use. reach 50 of focal lens. on nex systems you must set your camera to telephoto without tripod. this option will take pictures in 3 layers and make one single image. works great.
Excerpt: I am a new camera operator so this review is strictly based on my experience with the lens and camera. I am using the lens with my new K500 Pentax camera. I purchased the lens to get close up photos of my twin daughters in the Marching Band. If I'm in the stands I still don't get very close images.
Summary: This lens starts getting soft around 125mm and has problems with sharp focus action photos. And it's caused me extra post process time. All said and done, I should have purchased a better lens. I may try to return it.

Summary: Taking photos of my grandson's baseball game and was disappointed in the focus and sharpness of the photos. I felt I had the DOF correctly. I then used my Sony lens 70-300 f/4 the next day the differences were night and day. The Sony was significantly sharper.
