Learning More About Focal Length & Your LensesД«eginning photographers should spend some time learning about the focal lengths of the lenses they own.

Super Telephoto/Ultra Telephoto вЂ“ 300mm and above.

Below weвЂ™ll cover what each of these lens categories is used for in more detail, but this will provide a general idea of the range of focal lengths you might find stamped on your lenses: In general, these are the categories of focal lengths youвЂ™ll find among major camera brands. TheyвЂ™re popular in lower light and with portrait photography. Prime lenses have benefits over zoom lenses because they tend to be lighter weight and also have larger maximum apertures or f/stops. YouвЂ™ll know your lens is a prime lens because the focal length will be a single number listed in front of the millimeter measurement (e.g. They are sometimes called вЂfixedвЂ™ lenses because the focal length is fixed at one distance between the lens and the image sensor to keep the subject in focus. Prime Lenses вЂ“ In contrast, prime lenses only have one focal length. The line indicates the exact focal length you are shooting at between the minimum and maximum focal length range.

It should appear as a series of increasing numbers with a line that moves up and down as you increase or decrease the zoom. Zoom lenses will be printed with the range of focal lengths, but they will also have a focal length guide along part of the zoom ring. You can carry less camera equipment but still, have a subject in focus at any of those distances. Zoom lenses have great utility because they capture all the focal lengths in between the range. 18-55 mm means that the minimum distance is 18 mm and the maximum distance between the lens and the image sensor is 55 mm.

Zoom Lenses вЂ“ For zoom lenses, youвЂ™ll see both the minimum focal length and the maximum focal length that can be captured by the lens printed directly on your lens. To determine if your lens is a zoom lens or a prime lens, simply look at the focal length numbers on the camera lens. Prime lenses-also called fixed lenses-can only capture one focal length. Zoom lenses allow you to capture a range of focal lengths using the same lens. There are two types of lenses: zoom lenses and prime lenses. The difference between a focal length range and fixed focal length will indicate if your lens is a zoom lens or a prime lens.

Larger numbers indicate a narrower angle of view and higher magnification or zoom.Дepending on the type of lens that you own, the focal length will either be listed as a range of numbers (e.g. Smaller numbers equate to shorter focal lengths and lower magnification.

Measured in millimeters, focal length is the not the length of the lens, but how much of the scene will be in focus (angle of view) and the magnification (how large it will be relative to the original). Arguably, itвЂ™s the most important thing you need to know about your current lenses and itвЂ™s very important when buying new ones. LetвЂ™s break apart what both focal length range and maximum aperture mean for your own lenses.Д®very lens in your kit will have a focal length listed on the lens. Lens speed or maximum aperture will be listed as some number immediately following the letter f. Focal length range will be listed as XX-XX before the letters mm, (e.g. When comparing lenses, the two most important numbers are the focal length range and lens speed.
