Knowing these factors will help you better understand the role focal lengths play in your photography and help you work out which type of lens is the most useful for. To help you select the best camera lens for your needs, we put together a camera lens buying guide.

There are two different types of lenses, regardless of their focal length; zoom lenses and prime lenses. Zoom lenses can change focal length. You may have seen a lens that extends or contracts when twisting it on the camera enabling the user to zoom out or zoom in on their subject. A 24-70mm zoom lens operates at 24 at its widest and at 70mm focal length at its most zoomed in. It affords flexibility without having to change lenses, which makes them the best camera lens for travel, as you only need one zoom lens in your kit to cover all your bases.

Many beginners put a lot of their focus on choosing the right camera body, but the lens you choose has a huge influence on the final look of your image. Not only is the lens (or glass, as it's sometimes referred to) responsible for bending and shaping the light, but it's also responsible for the field of view you’ll see through the finder.

DC-iris lenses have an automatically adjustable iris opening that responds to changes in light levels. This gives them a significant advantage in situations with varying light conditions compared to a lens with a manually adjustable iris opening.

Our i-CS lenses use the latest standard and have three motors that enable automatic and remote control of all lens functions, such as zoom, focus and iris opening. The i-CS lens uses an open protocol developed jointly by Axis Communications and Computar®. Thanks to the protocol and information from the lens, the camera can always optimize its image quality. The lens can perform Barrel Distortion Correction (BDC) using geometric distortion data as well as stabilize the image with Electronic Image Stabilization (EIS).

Put simply, a focal length is the measurement of a lens attributed in mm. Often people mistakenly think that this measurement refers to the physical length of the lens. It actually refers to the angle of view of the lens when focused to infinity. This dictates how magnified your subjects will be when using the lens and how far away from your subject you can be for optimum use.

Super-telephoto lenses are, as their name suggests, super-long telephoto lenses and often veer into 300mm and above. These lenses have the invaluable ability of getting you a tight crop of subjects that are considerably distant, which makes them perfect for professional sports and wildlife photography.

P-Iris is an automatic, precise iris control developed by Axis Communications and the lens manufacturer Kowa. It includes a P-Iris lens with a motor and specialized software. The P-Iris system addresses the shortcomings of an auto-iris lens and improves contrast, clarity, resolution and depth of field.

It’s easy to be a little daunted when it comes to choosing a lens for your camera. The different sizes, weight and numbers associated with camera lenses can become overwhelming, but understanding what focal length is and what it does, will better help you decide the best lens for your type of photography. Here’s a guide to focal length, explained simply.

When we create our fixed box cameras, we carefully select a lens that provides the best image quality for the most common installation scenarios. To cover more special requirements, we offer a wide range of optional lenses. In our portfolio of CS-mount lenses, we have lenses with extreme light sensitivity, telephoto lenses that provide a high level of detail, P-Iris or DC-iris lenses, as well as i-CS lenses. All our lenses are varifocal and support megapixel resolution and IR correction for day/night cameras.

A prime lens is a fixed lens in that its focal length cannot be changed. You need to change lenses to adjust the focal length. Prime lenses most commonly come in the 35mm, 50mm and 85mm varieties. Prime lenses are not as versatile as zoom lenses but they usually provide superior optical and low-light performance, at a lower price point.

Telephoto lenses are longer lenses and offer a far greater capability to zoom in on a subject. 70-200mm range lenses are commonly used by portrait and event photographers, while they are also useful for sports and wildlife photography.

A shorter focal length is presented by a smaller number, such as 16mm. This will provide you with a wider field of view more commonly used when you want to get more into your photographs, like landscapes for instance. A longer focal length, such as 400mm, provides a much narrower field of view and is used to zoom in on something such as an animal or a person or object far away.
