Lenses with shorter focal lengths will have a wider field of view. Lenses with longer focal lengths will have a narrower field of view, but increased magnification.

Short focal length lenses will give you a wider field of view, but offer less magnification of the subject. Long focal length lenses give you a narrower field of view, but magnify whatever is in the frame.

Long focal lengths include all telephoto lenses—anything that captures a field of view that’s tighter than what the eye can see.

Telephoto lenses get more expensive and much heavier as the focal lengths increase to account for all the elements on the inside of the lens. Wide-angle and telephoto lenses are available as both prime or zoom lenses.

Zoom lenses can be more convenient and versatile than a prime lens because you can cover a wider field of view without having to change the lens.

We recommend keeping it simple if you’re just getting started with photography. A standard 24-70mm zoom lens and a 50mm prime lens are a great place to begin your exploration with focal length.

Long focal length lenses are popular choices for weddings, wildlife, or sports photography. Short focal length lenses are good for architecture, landscapes, street photography, or photojournalism.

A wide-angle lens is a good choice for shooting sweeping landscapes, large group portraits, or for off-kilter street photography.

If your passion lies in photographing weddings and corporate events, an ultra-wide fisheye lens won’t be very useful to you.

Canon’s mirrorless 35mm lens is officially called the RF35mm F1.8 Macro IS STM lens. Here’s what all of those letters and numbers mean.

Prime lenses tend to offer wider maximum apertures, which is why photographers refer to them as being fast. The technology inside of a prime lens is quite simple compared to a zoom lens, which makes them more affordable.

If that same performer is doing an intimate night at a club, a prime lens with a fast aperture and a wider field of view might be a more appropriate option.

Super telephoto lenses are anything with a 300mm focus length and above. Lenses on cameras with such long focal lengths are typically only used by the pros.

Wide-angle lenses are lenses that cover up to a 35mm field of view. This field of view is wider than the human eye and will increase your scope.

Not sure what focal length your camera lens might be? Luckily, you don’t have to make any tricky optical measurements to figure it out.

Telephoto lenses are anything with a focal length of about 85mm. Short telephoto lenses are a popular focal length for all styles of photographers because of their versatility.

Choosing a focal length is one of the most important decisions you can make as a photographer. There’s a reason that professional photographers have a collection of lenses at their disposal to make sure the focal length matches the moment.

These are the lenses that almost every photographer has in their kit. Standard lenses cover a focal length range of 35mm-85mm and can be a prime or zoom lens.

This style of lens can regularly be spotted on the sidelines of sporting events or by photographers who specialize in photographing dangerous wildlife, where keeping your distance is crucial.

This online simulator is a great visual tool for focal length comparison. Play around to see how lenses with different focal lengths will capture the same scene.

The technology inside of a zoom lens is more complicated, and the price of a standard zoom reflects that. Generally speaking, they also have maximum apertures that don’t open quite as wide as a prime lens.

Zoom lenses offer a range of focal lengths within a single lens. A 24-70mm is a classic camera focal length for a zoom lens and a popular choice that comes bundled with a camera body.

A telephoto lens refers to anything with a focal length of 85mm and above. These lenses produce a tighter field of view and mean that you can photograph subjects without getting super close.

Considering what you are shooting and where you will be working is an important first step. If you’re covering a massive concert at an outdoor venue, a telephoto zoom lens will help you grab detailed shots of the performers, but also shots of the general atmosphere.

The focal length of a lens is determined by the optical distance between the focal plane and the center of the element when the lens is focused at infinity.

The former refers to how much of the scene will be captured. The latter lets you know how large the individual elements will appear in the frame.

Lenses with longer focal lengths tend to be much more expensive, so before you buy consider your needs. There is absolutely no reason to break the bank on a super-telephoto lens if you’re primarily interested in portrait or still life photography.

It is also often used in music videos for a distorted, fun, and quirky take on a scene, sometimes creating subtle optical illusions.

However, an environmental portrait photographer capturing an artist in their studio might want a wider field of view to help bring additional elements into the frame.

Short focal length is an umbrella term to describe any lens that falls in the category of wide-angle or standard. A lens with a short focal length can include anything that falls between 4mm – 85mm.

Choosing which lens and what focal lengths you are going to use when taking pictures is one of the most important decisions you can make as a photographer.

If you are shooting on an analog camera, the focal plane is the piece of film. If you are using a digital camera, that focal plane is the camera’s digital sensor.

The camera focal length determines what is going to be in frame, but it also determines just how close you will be getting to your subjects when you’re taking the picture.

Short telephoto lenses are popular choices for photographers capturing live music, weddings, and portraits. Medium telephoto lenses cover a range of 135mm-300mm and are an important lens choice for sports and bird photographers.
