Which Camera Lens To Use

Even if prison cell phone cameras keep improving and reach unimaginable levels of image quality, I'll ever deport around a larger, heavier, and more complex camera. Why is that? One word: lenses! An interchangeable lens camera opens up a vast earth of photographic visions through a huge variety of eyes. Choosing among the dozens and even hundreds of lenses tin can be disruptive and intimidating, and so in this beginner'due south guide, I'll explain the types of lenses available and what you should buy.

What Does a Lens Exercise?

A lens focuses light to form an image on the camera's digital sensor or film aeroplane, much the way our eye works. And importantly, a lens determines how much of the subject is seen and captured, from the broad sweeping view of a wide angle lens to the narrow, selective view of a telephoto lens. We call this the angle of view.

Lenses are classified by their specific focal length in millimeters. At the simplest level, this millimeter marking corresponds to the altitude betwixt the lens'south optical center and the camera's image sensor when focused. From that focal length designation, we know how an prototype will await – in particular, the angle of view – on a given camera. Focal length is the most important factor to determine which lens to apply for a given photo.

Notation that the images above are taken with a full-frame camera – i.due east., a camera with a sensor that'southward most 24×36mm in size. If your photographic camera has a smaller sensor like aps-c or Micro Four Thirds, it will human action as a "ingather" of the images above and give a more zoomed-in appearance at each focal length. To exist specific, aps-c cameras have about a 1.5× crop factor, and Micro Four Thirds cameras have nearly a two× crop cistron. (For the remainder of this commodity, any time I mention specific focal lengths, I'll be doing so in terms of a total frame camera. To get the equivalent number on your camera, it'southward as easy equally dividing by your crop factor.)

Crop factors of various sensor sizes

Along with focal length, a lens also has a diaphragm that can change size – commonly chosen aperture – which controls how much calorie-free is permit through the lens (part of how we control exposure). As your aperture changes, information technology looks similar this:

Equally you can see, an f-stop similar f/16 represents a much smaller aperture opening than something like f/2.8.

Every lens lets you change the aperture size, so yous're non stuck at ane discontinuity. However, lenses are ordinarily named by their maximum aperture because information technology'southward so important – for case, the Nikon 28mm f/2.8 has a 28mm focal length and a maximum aperture of f/ii.8. Other lenses have maximum apertures of f/4 or f/5.6 (which don't let in every bit much lite), and some go the other management to f/one.4 or f/2 (capable of capturing much more light).

Aperture doesn't simply modify how much light yous capture. It besides determines how much of our subject is in focus from forepart to back – what nosotros call depth of field. As the discontinuity narrows, depth of field increases, which is why landscape photographers often use apertures similar f/eight, f/11, or f/16 to get sharp focus from forepart to back.

Combined, these two factors – focal length and discontinuity – are the virtually important features of a lens. If you lot know a lens'due south focal length(southward) and maximum aperture, you already know a neat bargain about what subjects it's intended to capture. I'll cover more than about those intended subjects next.

The Normal Lens

Lenses with a "middle" focal length – not super wide, non super telephoto – are known every bit normal lenses or standard lenses. Many photographers swear by the normal lens equally their master tool because information technology does not exaggerate perspective and can exist pressed into service for a wide variety of photographic needs. Photos taken with a normal lens feel similar looking at the world with your eyes, not a photographic camera.

The normal lens for a given camera organization has a focal length similar to the diagonal length of that camera's sensor or picture. Full-frame cameras (again, with a roughly 24×36mm sensor) have about a 43mm diagonal. The classic normal lens on total-frame is a 50mm, which is a bit longer than 43mm but pretty like.

Normal/standard lenses were most always sold with the camera equally a kit in the film days of decades past. Today, there are still plenty of 50mm lenses available from each manufacturer (or equivalents for smaller sensors like 35mm and 24mm lenses).

Everything from family candids, low-lite street scenes, wedding grouping photos, and even landscapes look natural with a normal lens. It's a flexible tool.

Broad Angle Lens Drama

Wide angle lenses can be exciting to look through, as they take in a much more expansive view than the normal lens and can be used to exaggerate perspective in pleasing means.

A typical employ for a wide angle is in a dramatic landscape, where the wide field of view allows you to get close to an interesting foreground such as a field of wildflowers, while still capturing a sweeping view of the mountains in the groundwork. Wide angles are as well commonly used in architectural photography, such equally including all of the grand interior of a cathedral in the photo.

On full frame, wide bending focal lengths range from most 10mm (uncommon and excessively wide for many uses) to 35mm (which is long enough that some photographers consider it a normal lens rather than a wide-angle).

Telephoto Lens Power

A telephoto lens is like looking through binoculars – it has the power to bring your subject up close and personal. A telephoto has a selective angle of view and is commonly used to photograph more distant subjects such as wildlife or sports. It tin also make pleasing head and shoulders portraits of people from a relaxed and comfy distance.

If y'all can't get close to your subject area, chances are yous will want a telephoto lens. They are my personal favorite lens type for landscapes, where I can compose a moving picture of a photogenic section of a forest rather than taking in the entire hillside. Telephoto focal lengths begin at 70mm and go along upward to near 800mm.

Specialty Lenses

Within the broad categories of wide angle, normal, and telephoto lenses, in that location are also more specialized optics. For example, a macro lens is designed to focus very close so that tiny objects such every bit insects, flowers, or jewelry can fill up the frame. Some other specialty lens is the high-speed (or fast) lens, which has larger lens elements and a wider maximum aperture – great for letting in more light and capturing very shallow depth of field photos, where non much in the image is in focus.

Other speciality lenses included fisheye with its extreme and distorted field of view, tilt/shift lenses which are used by some architectural, studio, and landscape photographers to more than precisely command perspective and focus, and the huge, exotic super-telephotos seen on the sidelines of major sporting events.

Primes vs Zooms

A prime number lens has a single focal length, such as the 50mm normal lens. A zoom lens has a range of continuously variable focal lengths, such as a 24-105mm lens. You turn the zoom band on the lens barrel to zoom in from a wide-angle 24mm perspective toward a telephoto 105mm.

Prime lenses are oft smaller and lighter than zooms, and they frequently take a larger maximum aperture. Prime lenses too tend to provide somewhat ameliorate optical quality than zooms. But zoom lenses win the convenience honor, assuasive you to carry ane lens that replaces a whole bag of fixed focal length primes.

The very best zoom lenses these days are then proficient optically that virtually photographers will not need to worry near the optical differences. Both primes and zooms tin have their proper identify every bit a photographer'due south lens kit grows.

Cost vs Performance

Lenses come in all price ranges, and skilful options be in the upkeep range. Spending more than coin may get you a college level of build quality, more refined optical qualities, or wider apertures, but for the beginner, at that place is no reason to overspend.

Any modern lens should allow yous to take pictures as excellent every bit your skills allow. If you do continue to enjoy photography and develop your skills, a time may come when spending more money will get you an upgrade in ane of the same areas.

OEM vs Third Party

Each camera manufacturer such as Canon, Nikon, and Sony has its own line of lenses designed to fit its specific cameras, and most of these lenses tend to be very practiced to excellent and are a condom option. But in that location are also third-party, lens-simply manufacturers such equally Sigma and Tamron who are turning out great optics and unremarkably at lower prices than the OEM lenses. Perusing the lens reviews here at Photography Life will help give y'all ideas of what lenses are available and how they measure up.

New vs Used Lenses

New lenses are a safer bet as yous usually have xxx-twenty-four hours return privileges if not satisfied, and you don't take to wonder how the lens was treated by previous owners. You lot besides have a manufacturer's warranty if y'all purchase from an authorized dealer for the make you choose.

For bargain hunters, used lenses can bring the reward of money saved, simply there is the chance of getting a lens that does non perform as information technology should. There are a wide variety of potential bug with precision products similar lenses, such every bit a lens element that is out of alignment, autofocus motors dying, dust or mold within the optics, or wear and tear on the barrel.

I advise beginners to buy new, or make sure there is a return privilege for used lens purchases purchased from a reliable seller (B&H Photo is an excellent option for new and used; KEH Camera is bully for buying used with good warranty).

Choosing I Lens to Commencement With

Armed with this basic introductory info near lenses, now the fun begins: choosing your outset one.

The classic, disciplined approach argues for a 50mm normal lens, and these have the advantage of being among the nearly affordable, lightweight, small, bright (AKA wider aperture), and optically excellent lenses in any manufacturer's line. Equally a beginner, using a 50mm lens for a wide multifariousness of photography will teach you much well-nigh what your own needs are for your ultimate lens kit. If you photograph in minor spaces, yous may eventually meet the need for a broad angle, or if you spend much of your photography taking pictures of children's soccer, you'll presently understand the need for a telephoto. A 50mm standard lens is a great instructor.

If y'all want to photograph a wide variety of subjects with convenience, a more versatile first lens purchase would be a wide-to-telephoto zoom, something like a 24-105mm or 28-200mm. With zooms like this, yous'll take all the most important focal lengths covered in one parcel, and you just demand to turn the zoom band to find the correct perspective for your subject.

The more pocket-sized the zoom range, the better optical quality tends to be. 24-70mm lenses usually beat 24-120mm lenses, which usually beat 24-200mm lenses. (They likewise tend to exist lighter and/or have a larger maximum aperture.) I find that 24-105mm and 24-120mm lenses are the best compromise. They're not just a proficient beginning lens for beginners, but also a beloved optic any time you demand a versatile lens on your photographic camera. I use a 24-120mm f/4 constantly on my ain organization.

From landscapes, to travel, to family unit candids, to love pet portraits – the 24-120mm is versatile!

To add a chip of discipline as you're starting out with a zoom lens like this, I recommend a beginner take the 24-105mm zoom and for the first few months of their photography only use the lens at three marked focal length settings: 24, 50, and 105mm. It volition be as if yous take three primes in your bag, and you'll learn from this exercise how to choose the focal length to suit the perspective and limerick you desire for each subject.

If you are a beginner who already knows you are going to exist spending most of your camera fourth dimension photographing sports or wildlife, and you lot just want ane lens to offset with, so consider bypassing the wide and normal views and choose a seventy-300mm or 100-400mm every bit your beginning lens. This way you are equipped with the telephoto range needed for distant subjects, and you can use your iPhone for the normal and wide views when taking family snapshots or vacation pics.

Building A Multi-Lens System

Here's where it gets more fun! If you plan from the kickoff to build a organisation of two or more than lenses, you can expand on my recommendations higher up and apply multiple lenses that complement each other.

If choosing the versatile 24-105mm recommended above, lens number 2 (when you're ready) could exist a 100-400mm to become a telephoto perspective, a 50mm f/one.8 to go a wider aperture, or a 16-35mm to get a wider angle view.

Alternatively, nature lovers may eventually want a macro lens to help capture close-ups of the tiny world, and a 100mm macro is a superb complement for almost any other lens kit. Since well-nigh macro lenses have a large maximum discontinuity of f/two.8 or then, they tin can also double as a portrait lens that offers a squeamish, shallow depth of field effect. Or y'all tin go to more exotic fast-aperture primes if portraiture is your specialty, such as a 85mm f/1.two or 135mm f/1.eight.

Savor the View!

Lenses are the life of the interchangeable lens camera, and truly the all-time style for a beginner to expand their vision through the virtually limitless world of eyes. From the drama of wide angles, to the just-correct condolement of the standard lens, to the powerful earth of telephotos, the view from a adept lens is seductive and just may lure you into the joy of photography for the rest of your life.

I hope you've glimpsed the fun that can await you as a beginner looking to choose your start lens or build a multiple lens organisation. I welcome your comments below!
