In chapter one we covered the basics of lens technology and discovered the difference between wide angle and telephoto lens systems. We also saw how larger apertures are usually an indication of lens quality as they let in more light, making faster shutter speeds possible in dim light. We have learned that the greatest advancement in lens technology in resent years has been the advent of silent motors for auto focus, new glass for lens elements such as the Nikon ED glass and Vibration Reduction or Image Stabilization.
NOTE: this chapter contains separate tutorials that you need to follow page after page, hitting the button "NEXT", unlike the chapter 1 we had, which was divided into " 1.2, 1.3, 1.4...etc". And so we will continue with the other chapters, with the system "all in one".
