Think More About Lenses, not Just Your Camera Body

Are you still confused about which lens to buy and why it matters so much? Is it hard to stop thinking about that brand new Canon camera body you want to badly? Stop for a minute, read my article and hopefully you'll understand why it's the lens that matters most when taking photos.

I've said it probably more than once, but I'm going to say it again; DSLR camera bodies these days are SO GREAT. You could spin in a circle and point to one at the store and be happy with it! Even bodies that were new 2-3 years ago are still GREAT. The difference is made when you are using a good lens. What do you need to consider when choosing a new lens? 

• FOCAL LENGTH

• MAXIMUM APERTURE

The focal length of your lens is the mm of length it offers. For example, the 18-55mm kit lens your camera most likely came with, zooms in and out from 18mm - 55mm. A 50mm lens is FIXED; it offers one focal length, doesn't zoom and that's that.

The maximum aperture means the lowest your f/stop # will go on your lens. Every lens has a limit to how 'wide' it can open up to let in light. For example, on that 18-55mm f/3.5-5.6 lens, at 18mm (zoomed all the way out) your f/stop will not go past f/3.5. At 55mm (zoomed in) your f/stop can only go to f/5.6. Lenses that offer larger maximum apertures, such as f/2.8 or f/1.4 will be more expensive, because they let in more light and are more versatile. If your budget can afford it, a lens with a larger maximum aperture is always a good choice! Unfortunately, they can get quite expensive. 

Something to Think About: 

• Fixed lenses are good quality and offer SHARP images and a lot of the time, let in more light allowing you to take photos in lower-lit settings. About that budget? You can get a Canon 50mm f/1.8 lens for only $125! The Nikon 50mm f/1.8 is $216.95. 

• Zoom lenses will allow you to zoom in and out on subjects without physically moving, but have moving parts so they aren't quite as sharp as FIXED lenses. 

Ask Yourself These Questions:

1. What do spend most of my time photographing? What is my subject matter? 

2. Which is more important, image quality or having an all-around lens with the ability to zoom? 

3. What is my budget for gear? 

Once you determine what style or look you are going for, what you will be shooting and how much you have to spend, you will be ready to narrow down your lens selection and find one that works great for you! If you photograph products, food or take portraits, the 50mm fixed lenses mentioned above are an AWESOME addition to your camera bag, at a low price. Having that lower maximum aperture will change your photography!

Understanding Lens Selection

Now that you have your DSLR, it's time to switch gears and consider lens selection. Before choosing the right lens you need to know a little more about how they work! The first thing to understand is that every lens has a certain focal length(s) which is measured in millimeters (such as 50mm). This focal length, paired with the kind of sensor your camera has, determines how much can fit into a photo. 

Shorter focal lengths or wide angle lenses such as 20mm or 35mm allow you to be close to your subject (they fill most of the frame) and the background seems to be farther away. They also allow you to fit more into your frame.

Longer focal lengths, such as 105mm or 300mm lenses, allow you to stand farther away from your subject (having your subject fill your frame) but the background seems closer than normal. These lenses make a smaller area look larger (the higher the focal length number is, the more zoom you'll have). Let's break it down into the types of lenses there are and why you would want to shoot with these lenses. 

Wide Angle Lenses: The shorter your focal length is, the wider your angle of view will be or the more you'll be able to fit into your image. A wide-angle lens is usually considered anything under 35mm. This is especially useful for landscapes and interiors; trying to fit as much of scene in a photo as you can.

Standard Lenses: Standard lenses (such as 50mm or 85mm) are great for portraits and everyday scenes. A 50mm lens acts similar to the way our eyes see a person or subject; thus being a standard lens (with standard magnification) making our subject look more natural. Most cameras come with a kit lens, such as an 18-55mm lens. 

Telephoto Lenses: Telephoto lenses don't fit as much in the frame. This allows you to get closer shots of your subject and have a smaller depth of field (easier to get a blurry background). Telephoto lenses can be great when shooting portraits, wildlife and/or sports because they allow you to get close to your subject. 

When considering a lens, it is important to remember that not all DSLR camera's have the same size of sensor. The lens and the sensor go hand-in-hand so be sure that the lens you buy is compatible with the format of your sensor. Most entry-level DSLR cameras have a smaller or cropped sensor (like an APS-C sensor); when choosing a lens, a standard 50mm lens acts like a 35mm lens on a cropped-sensor camera (the view isn't as wide as it would be if the lens was on a camera with a full-frame sensor).

Here's a list of what companies label their APS-C format SLR lenses:

• Canon - EF-S

• Nikon - DX

• Pentax - DA

• Sony - DT

• Sigma - DC

• Tamron - Di II

• Tokina - DX

You can use full-frame camera lenses on an cropped-sensor camera, but these APS-C format lenses will not work properly on a camera with a full-frame sensor. Keep this in mind if you plan to upgrade to a full-frame camera body in the future. Each camera has a certain kind of lens mount as well, which means how a lens physically fits onto the camera. You won't be able to mount a Canon lens to a Nikon camera :) 

Lenses are categorized into two categories; fixed or prime lenses and zoom lenses. A fixed lens stays at one focal point (like 50mm) and doesn't have any moving parts. They are smaller, lighter and allow for brighter, sharper images. Since they have no moving parts, the glass provides higher quality images. Fixed lenses are considered 'faster' because they have large apertures (like f2.8) which let in more light. Zoom lenses (such as 18-55mm) allow you to move from one focal length to another. These can be convenient but you'll give a little of the quality when choosing a zoom lens. They just aren't quite as sharp as fixed lenses.

Consider your subject matter and what you spend the majority of your time photographing. This will determine the kind of lens you want to invest in. If you shoot sports, wildlife or street-style photographs, a zoom or telephoto lens would be a great choice for you. If you want great portraits, investing in prime lenses is the direction to go. If you want an all-around lens to travel with that will give you a good range, something like an 18-200mm lens would be nice to have. Cameras are excellent these days, the real difference is made when you pair your DSLR with a great lens. They can be expensive but the investment is worth it to get great images. We'll cover more about recommended lenses soon!
