Differences In Camera Lenses

As a first-time photography enthusiast, deciding on the right photo equipment can offer a confusing array of options. When it comes to lenses, understanding the differences in focal lengths can save you money in the long run.


Features


Lenses are grouped according to their angle of view and focal length, and are sold as either a fixed-focus (e.g. 50 millimeters [mm]) or zoom (e.g. 70-300 mm). The majority of lenses on the market offer a combination auto-focus (AF) and manual-focus (MF) feature.


Wide-angle Lens


Wide-angle lenses range from 8 mm (considered a fisheye lens) to 35 mm. Wide angles are ideal for shooting landscapes, as they capture large portions of scenery.


Standard Lens


Standard or normal lenses come in 50 mm or 55 mm and are called such because the lens reflects what the human eye sees, offering a "normal" view of the subject.


Telephoto Lens


Telephoto lenses range from 80 mm to 800 mm and are best used when you're at great distance from the subject, such as a sporting event or an animal's habitat.


Macro Lens


Macro lenses, offered in fixed-focus and zoom, are perfect for making a small subject appear life-sized on the final print.
