How Does the “8x” Zoom on My Point-and-Shoot Compare to My DSLR?

Your camera may boast “8x zoom”, but most DSLRs do not advertise values like these. So how do they compare? The answer is more complex than you may think.

That “8x” value that doesn’t necessarily mean objects in the photo will look 8 times bigger than they do with your eyes. It just means things will be 8 times bigger than its most zoomed-out position—but two cameras in their most zoomed-out positions will not look the same size.

Every lens affects your image in a different way. A wide angle lens warps the perspective in the image so it shows more than you could see with your naked eye. A telephoto lens does the opposite, zooming in like a telescope to distant objects. These things are separate from the actual “zoom” function on your camera, so one 8x zoom lens may not make objects as large as another 8x zoom lens.

So how do we calculate how much bigger an object appears in a photo compared to your eyes, where you’re currently standing? To find that out, you need to know the focal length and field of view of the lens you’re using.

Focal Length and Field of View

In photography, the focal length of a lens is the distance between a the camera’s sensor and the internal components of the lens itself. This focal length determines how close objects look to your camera and what part of the scene actually fits within the picture—otherwise known as your field of view. A massive, telescope-like lens with a 1000mm focal length will make objects look very close. Lenses with smaller focal lengths will make objects appear farther away.

Many lenses can “zoom” to different focal lengths. For example, an 18-135mm lens will let you zoom from an 18mm focal length to a 135mm focal length.

Here’s an example. I shot the following two images with my Canon 650D and an 18-135mm lens.

The first photo was taken at the shortest focal length: 18mm. It’s a pretty wide field of view.

The next photo was taken in the exact same place half a second later. The only difference is that I’ve zoomed in to use the lens’ longest focal length, 135mm.

As you can see, the field of view is a lot narrower in the second photo than the first, because we’ve zoomed in on the mountains.

Here’s the catch, though. Different lenses, at their shortest focal length, will show things differently. Remember that 1000mm telescope lens? Even if you don’t zoom in with it, you’re still seeing things much closer than a camera with an 18-135mm lens. So focal length alone isn’t…

What Lenses Should I Buy for My Canon Camera?

The biggest advantage DSLRs have over smartphones and compact cameras is swappable lenses that suit what you’re trying to shoot. Whether you want a lens that can blur the background for great portraits or something that lets you zoom in close to the action, there will be one available.

Lenses, however, are expensive. With so many choices, you need to be make sure you’re getting the right one for your needs. A well looked-after lens will last for years so it shouldn’t be a throwaway choice.

If you’re already an experienced photographer, this article probably isn’t for you. I’m not going to be recommending any super expensive, professional quality glass. Instead, I’m going to look at some of the best options for beginner and intermediate photographers who are looking to shoot new things.

Before diving in, it’s important to note that Canon has two different lens mounts: EF-S and EF. EF-S lenses will only work on crop sensor cameras like the entry-level Canon EOS Rebel T6. EF lenses will work on all Canon’s DSLRs.

If You Want to Shoot Portraits

For portraits, there are two things you need: a focal length of between about 50mm and 100mm, and a wide aperture. This focal length range gives you natural looking portraits without too much distortion and the wide aperture lets you blur the background to nothing.

The Canon EF 50mm f/1.8 STM fits both these criteria perfectly, and at $125 is an absolute steal. There are very few lenses this good, available that cheap. I still use the one I bought when I first started portrait photography regularly.

If You Want to Shoot Sports or Wildlife

Sports and wildlife photography are technically very similar: you want close up photos that show the action, but, whether because you’re stuck on the sideline or can’t sneak up on a wild…
