Zoom lenses does not have a fixed focal length. The focal length of the lens can instead be adjusted over a range of focal lengths. A commonly found model allows adjustments from 33 mm to 135 mm. Many zoom lenses also offers a macro mode, which allows close-up photography. While zoom lenses offers a great deal of flexibility in a single package, they are not the answer to everyone needs for lenses. Zoom lenses tend to be bulkier than fixed focal-length lenses. These are not quite as sharp unless a very high-quality is use. They are usually slower than an equivalent fixed lens.

Ultraviolet and skylight filters are designed for every specialized purposes. The ultraviolet filter, call a “UV” or “haze filter.” cuts out unwanted ultraviolet light, and the skylight filter can be used in color photography to “warm” bluish shadows. Most photographers buy the filters for other distinctly different reason (lens protections).
