Review title: DOA
Product review: I bought the D-510 because I had an Olympus film camera for a number of years and loved it -- great lens and the camera was small enough to take anywhere.Therefore, it was a great disappointment to find out that the camera I bought has the picture-taking functionality of a brick. The diopter adjustment never sharpens the focus of the optical viewfinder; the zoom lens doesn't zoom; and no picture is displayed in the LCD viewfinder....
