If landscape photography is your thing then wide-angle lenses will be your bread and butter. Moving on, we come to the single-lens part of the equation which, again, is fairly self-explanatory. For the best results, it is recommended to use a macro lens instead. Filter thread: Lets you attach lens filters to modify light that reaches your camera sensor 2. A telephoto lens is a lens that appears to magnify distant objects. Lenses originally did not auto-focus. Unlike modern lenses that are ‘chipped’, they couldn’t digitally communicate with the camera, so there was no AF, and couldn’t even speak automatically to the cameras to tell them what aperture they were at, and what focal length so metering properly was non-existent. With a DSLR, if your first lens doesn't have the wide-angle or zoom capabilities that you want, you can purchase additional lenses that provide more zoom or better wide-angle options. 17mm – Extreme Wide Angle (Architectural and landscape photography) Image stabilization, on the other hand, is inseparable from the process of image making. Prime lenses are lenses that have a fixed focal length. They are great for architecture photography. It has often been cited that 50mm lenses, when used on both film and digital 35mm SLRs is a ‘standard’ focal length.Anything longer than this is telephoto and anything wider is wide angle. It is only that the lens uses a shorter crop of the image coming through the lens which mimics the effect of a tighter composition (longer focal length). It depends on the path that each photographer takes. Magnification, minimum focus and more explained. ...

Close-up lenses are primarily used for macro photography to be able to get closer to the subject, decreasing the minimum focus distance of the lens. Zoom lenses are extremely convenient and their quality has improved enormously over the years, but they still have to make some compromises in order to enable the focal length shift.
