On the other hand, the smaller APS-C sensors come with a "crop factor" of about 1.5x to 1.6x, effectively increasing the focal length of lenses and providing extra "reach," which can be beneficial for telephoto photography such as sports or wildlife. Despite potentially higher noise levels in low light, APS-C cameras offer a more compact and affordable option for those seeking a balance between performance and portability. This makes them attractive to amateurs, enthusiasts, and even professionals who value a lighter system.

Generally, choosing a long focal length lens, like 70mm, 135mm, or 200mm, is wise to isolate textures and distant features to create dramatic backgrounds. Wide focal length lenses, like 16mm, 24mm, or 35mm, thrive when you want the entire scene in focus, like when shooting simple landscapes with long leading lines.

Lens compatibility is another consideration; full-frame lenses can be used on both sensor types, but APS-C lenses on full-frame bodies may result in vignetting. Finally, while full-frame cameras are more expensive, they are preferred for their superior image quality and flexibility in various shooting conditions. Conversely, due to the crop factor, APS-C cameras are favored for their affordability, compactness, and built-in telephoto advantage, making them a versatile choice for many photographers.

Telephoto lenses between 70 – 200mm are very popular lenses for portraiture and product photography as well as nature and wildlife imagery. They allow the photographer to produce close crops on the subject. In the case of portraiture a telephoto allows the photographer to take the photo at a distance that does not intrude upon the subject.

The magic of a prime lens lies in its simplicity. The straightforward optical design enhances light transmission, allowing for incredibly clear and precise images. This can make a noticeable difference in your photography, especially when shooting in low light conditions. Moreover, with minimal distortion and chromatic aberration, your photos will have a professional sleekness that’s hard to achieve with a standard zoom lens.

Lastly, fisheye lens are a super fun addition to the camera bag if you’re into the widest view possible. Their angle of view is usually 180°, allowing you to see half of a full rotation and offering a distinctive, hemispherical lens distortion. They cram in as much information as possible; thus, they don’t produce straight lines. These are awesome for creative, experimental photography projects, especially within fashion portraits or skateboarding content.

Beyond the technical benefits, using a prime lens influences your creative process. Without the ability to zoom, you’re encouraged to physically move around your subject to compose the perfect shot. This often results in more thoughtful framing and a better connection with your subject. Whether you’re shooting portraits, street scenes, or landscapes, a prime lens can push you to explore new perspectives and enhance your compositional skills.

Prime lenses are the unsung heroes of the photography world. Fixed in focal length, they don't have the zoom capabilities of their counterparts, but what they lack in flexibility, they make up for in quality. Because they contain fewer glass elements, prime lenses can capture images that are not only sharper but also more vibrant.

A lens focal length combines various elements that help to focus the light and minimize distortions. The location where all the light rays converge to form a sharp image is known as the optical center of the lens.

Lens focal length tells us the angle of view—how much of the scene will be captured—and the magnification—how large individual elements will be. The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of view and the lower the magnification.

Focal length in photography refers to the distance between the lens and the image sensor when the lens is focused on infinity. It's typically measured in millimeters (mm) and is a key determinant of a lens's angle of view — the extent of the scene captured by the lens — and its magnification.

Let’s break it down: Wide-angle lenses (under 35mm) are your go-to for capturing vast landscapes and bustling street scenes. They fit more into the frame, which is great for sweeping views and architectural photography. Meanwhile, telephoto lenses (over 70mm) excel in bringing distant subjects into sharp relief. They're ideal for zeroing in on distant details, perfect for sports or wildlife photography, and they add a dramatic flair by compressing space, making elements in the photo appear closer together.

A wide-angle lens is often characterized by a focal length of 35mm or shorter, giving the photographer a wide field of view. The wider your field of view, the more of the scene you'll effortlessly capture in the frame. These lenses are ideal for many scenarios, and most photographers have at least one trusty wide-angle lens in their kit. If you’re a beginner photographer or want the first lens for a camera camera, it’s wise to go with a nifty 35mm lens focal length.

Long-focal length lenses range in the 100-600+ range and appear to bring far away objects close to the camera. Made swimmingly for the landscape photographers in mind, long lengths are perfect for wildlife, the bird on the backyard feeder, the child at the top of a water slide, or athletes on the other side of the football field. Lenses longer than 70mm focus on infinity after 100 feet. This infinity-focusing distance means a couple of different things.

These lenses provide a good range for wildlife and sports photography where the photographer is limited as to how close they can get to the subject.

Prime lenses are usually more compact and lighter than zoom lenses, making them convenient for travel and long shooting sessions. Their smaller size and weight are due to the absence of the extra glass and mechanics needed for zooming.

Prime lenses also tend to have a larger maximum aperture (f/1.4 to f/2.8). This is an advantage when shooting in low light conditions as it will increase the possibility of hand holding the camera and freezing the subject without shake or blur caused by the longer exposures. Photographing using prime lenses with large apertures also means you can get a shallow depth of field which is useful for portraiture where you might want a softer or blurred background (also known as bokeh).

With ten years under my belt as a professional photographer, I've found that telephotos are better than wide for my work — here's why.

Focal length, usually represented in millimeters (mm), is the basic description of a photographic lens. It is not a measurement of the actual length of a lens, but a calculation of an optical distance from the point where light rays converge to form a sharp image of an object to the digital sensor or 35mm film at the focal plane in the camera. The focal length of a lens is determined when the lens is focused at infinity.

Wide angle lenses are popular lenses for landscape photography, interiors, large group photos and when working in confined situations.

Standard lenses are popular as they are closest to the angle of view we humans see. These lenses have minimal distortion, which can be flattering to the subject. They tend to use large apertures and allow a lot of light to enter the lens which makes them fast in low light conditions. Large apertures (f/1.8 – f/1.4) also produce a pleasing out-of-focus effect to the background which concentrates the attention of the viewer on the subject. Standard lenses are the popular choice for a wide range of photography including portraiture, nature and low light situations where the photographer can not use a flash or is looking to capture the scene with available light.

They typically have larger maximum apertures (e.g., f/1.4, f/1.8, f/2.8), allowing more light to reach the sensor. This makes them excellent for low-light situations and for achieving shallow depth-of-field effects where the subject is in sharp focus against a smoothly blurred background.

If the lens marking is unclear or you want more details, the lens manual or the manufacturer's website will provide specifications, including the focal length.

Getting into the art of photography? Just upgraded to a new camera body and need to decide which lens to purchase? Finding the right lens for your needs depends entirely on the focal length. Are you shooting portraits, weddings, sports, or wildlife? Street? Food?

The differences between cropped (APS-C) and full-frame sensors are significant in digital photography, influencing various aspects of image quality, field of view, depth of field, and camera system size and cost.

Close-up photography uses a specific range of lenses that allow up to 1:1 reproduction. These lenses allow the photographer to focus very close to the subject and reproduce them at a 1:1 life-size ratio on film or an imaging sensor. These lenses are popular for subjects such as flowers, insects and small products.

While there is a broad range of pricing for prime lenses, they can be less expensive than zoom lenses of comparable quality, especially at wider apertures. This cost-effectiveness stems from the more straightforward construction and fewer materials required.

The simplest way to find the focal length of a lens is to look at its specifications. Most lenses have the focal length marked directly on them. For prime lenses, it will be a single number (e.g., 50mm), while zoom lenses will show a range (e.g., 24-70mm).

The most popular wide-angle zoom range is 16-35mm. Most kit or standard zoom lenses go down to 24mm or28mm. The widest lenses on the market are 10mm (rectilinear) and 8mm (fisheye).

Wide-angle camera lenses are a fan-favorite among most lifestyle bloggers and everyday shooters; they’re perfect for capturing an entire scene and confined spaces if you want to show how the entire bedroom looks or the whole restaurant with the crowds of customers — the shorter focal length lens will be your best bet.

There are two types of lenses-prime and zoom. Prime lenses have a fixed focal length and zoom lenses have variable focal lengths.

Then there's the standard lens, around 50mm, often hailed as the "nifty fifty." It’s akin to the human eye in how it captures the world, making it incredibly versatile. It’s perfect for everyday shooting and portraits, blending background and foreground elements naturally. As a beginner, using a 50mm lens encourages you to physically move around, engaging more with your environment, which can lead to more thoughtful compositions.

Focal length might sound technical, but it's really your secret weapon in framing the perfect shot. It's measured in millimeters and determines not just the angle of view—how much of your scene is captured—but also how your images are magnified. As a beginner, understanding this can transform the way you approach photography.

The main advantages of prime lenses or fixed focal length lenses are their size and weight as well as their maximum aperture or f/stop. Prime lenses tend to be more compact and lightweight than zoom lenses.
