by A camera lens plays a vital role in capturing quality images. Regardless of the type and specifications of a camera, its lens is what determines the quality and characteristics of the photographs it takes.
Types of Camera Lenses
There are several types of camera lenses available to photographers based on their usage, mount specification, and optical design. Some of the major lens types are:
Prime Lens
Prime lenses, also known as fixed focal length lenses, have a single fixed focal length. They do not have a zoom capability. As a result, prime lenses are generally smaller, lighter, and able to capture images with higher clarity and sharpness compared to zoom lenses. Some popular prime focal lengths are 28mm, 35mm, 50mm, 85mm, and 135mm.
Zoom Lens
Zoom lenses allow photographers to change focal lengths without having to swap lenses. However, zoom lenses tend to be larger in size and heavier compared to prime lenses. They also offer slightly lower image quality. Popular focal length ranges for zoom lenses are 18-55mm, 50-150mm, 70-200mm, and 100-400mm.
Specialty Lenses
Specialty lenses like wide-angle, macro, fisheye, and telephoto lenses serve specialized purposes. Wide-angle lenses capture a very wide field of view while macro lenses are used for close-up and extreme close-up photography. Telephoto lenses compress distance and enable reaching faraway subjects.
Lens Mounts
The three most common lens mounts used in modern interchangeable lens cameras are Canon EF mount, Nikon F mount, and Sony E-mount. Lenses from one system cannot be mounted directly on cameras of another system without using an adapter.
Understanding Lens Specs
Some key technical specifications that photographers must understand about lenses are:
Focal Length
Measured in millimeters, focal length determines the angle of view and magnifying power of a lens. A wider focal length (small numbers) provides a wider viewing angle while longer focal lengths zoom in and magnify the subject.
Maximum Aperture
Denoted by a f-number, maximum aperture specifies how much light a lens can gather. A lower f-number like f/1.8 lets in more light than f/5.6. It also determines depth of field and low light performance.
Image Stabilization
Image stabilization lenses, usually marked with “OS” or “VR”, counteract Camera lens shake using gyroscopic sensors. They enable handholding the camera at slower shutter speeds for blur-free images.
Lens Construction
Multi-coated lens elements, extra-low dispersion (ED) glass, and aspherical elements contribute to sharpness and clarity. Lens construction also impacts features like aberration correction.
Autofocus Type
Autofocus lenses can be ultrasonic (USM) or micro-ultrasonic (Micromotor USM) with faster and quieter focusing. Some have full-time manual override as well.
Different Focal Lengths and Their Uses
Understanding what focal lengths are suitable for which type of photography is important. The most commonly used focal lengths can be categorized as:
Wide-Angle Lenses
Ideal for landscapes, interiors, architecture, and capturing a large field of view. They help include more contextual elements in shots. However, they can also cause distortion towards the edges of frames.
Standard/Normal Lenses
The standard focal lengths that provide the closest representation to human vision. Used widely for available light portraits, street photography, travel, events, and more.
Short Telephoto Lenses
Provide some extrareach without too much magnification. Great for portraits, events, casual wildlife, and can also serve as a walkaround lens.
Telephoto Lenses
Essential for sports, wildlife, bird photography and other subjects where getting closer is difficult. Compress distance and isolate subjects from their backgrounds.
Macro Lenses
Designed for extreme close-up photography, capturing subjects from as close as 1:1 life-size magnification. Used for product, still life, jewelry, and detailed shots of small objects, insects etc.
Super/Ultra Telephoto Lenses
Highly specialized lenses used by professional photographers and enthusiasts. Capable of reaching distant subjects that are otherwise invisible to the naked eye. Integrated image stabilization is important for them.
Choosing the Right Lens
With so many lens options available, selecting the right one can be challenging. Camera systems bundled with 18-55mm zoom kits serve as versatile starters. Photographers then choose additional lenses based on their shooting needs and genres. It’s best to rent different lenses initially and understand their characteristics before making expensive lens purchases. Proper lens selection and understanding focal lengths go a long way in helpful creative photography.
