It is many years since I have been involved in photography and I bought this lens to go with my newly purchased Nikon D5200 body . I wanted a wider range than the normal kit lens and after researching various lenses decided to try this one . I am obsolutely amazed at the quality of some of the shots I have taken and attribute this to both the camera and lens . The camera ( as with most good quality cameras now ) allow me to view and correct immediately any errors I have with my camera settings but once these are right the quality from the lens is superb . This invariably is through the focal range and continues when I have added a Circular Polarising lens . It operates smoothly and quickly and is beautifully balanced as far as size and weight when added to the camera and feels "right" immediately . It does not have the metal thread of my prime lens but the overall quality is excellent and I think as long as it is treated with respect it will be a long time friend. I have enjoyed using my new camera and lens so much I keep planning different places to visit to challenge my improvement and although I have purchased another couple of lenses this will be my default lens because it is so good and I enjoy both it's flexibility and quality .
