This is why you can’t ‘zoom with your feet’

We all know the phrase ‘zoom with your feet’. It’s supposed to be an admonishment to photographers to stop being lazy with a zoom lens and actually move to get closer to their subject. But is it really accurate?

Scott from Tin House Studio doesn’t think so. In fact, in this video, he explains why this catch phrase is incorrect, and suggests a far better way to think about the difference between zooms and prime lenses.

False: Zooming with your feet is the same as using a zoom lens

Scott explains that the core misunderstanding is that moving closer to or farther from a subject (zooming with your feet) is the same as using a zoom lens. This is not true, he says. These two things produce fundamentally different results:

Zooming with Your Feet: Physically moving closer or farther from the subject alters the perspective. The relationships between objects in the frame are different. Elements in the background appear larger or smaller relative to the subject. This change can create distortion or emphasize depth, depending on the distance.

Zooming with a Lens: Adjusting the focal length of a zoom lens crops the scene tighter or wider without altering the relationships between objects within the frame. The perspective remains constant, and the background and foreground keep their spatial relationship.

The differences between a zoom lens and zooming with your feet

Moving closer to or farther from your subject changes how objects in the scene relate to each other, creating perspective shifts that a zoom lens cannot replicate. Getting closer also affects the depth of field, making it shallower because of the distance, not just the lens. While zooming with a lens lets you frame your subject tightly without changing the background’s appearance, physically moving can change or remove parts of the composition, leading to very different results.

When should you use a zoom?

So, how do you know whether to zoom with your lens or move closer to your subject? Well, it’s actually not that complicated, says Scott. To isolate your subject and crop out distractions without changing the perspective, use your lens to zoom in. However, if you want to control the spatial relationship between objects in the frame, zoom with your feet. For example, moving closer to your subject with a wide-angle lens can exaggerate depth, creating a bold and dramatic “hero” effect.

Prime lenses highlight the difference

Both prime lenses and zooms have their benefits. Zooms are incredibly handy and cover a wide range of focal lengths in one lens, making it more portable, and great for things like weddings and events when adability is important.

However, the advantage of a set of prime lenses is that a good photographer will know exactly what that 35mm or 50mm prime will look like before even putting the camera up to their eye. It’s a strange thing, but this ability to memorise seems to be particular to prime lenses.

With this in mind, photographers who use prime lenses (with fixed focal lengths) naturally work with both techniques. They must physically move to adjust framing, and this makes them aware of how perspective changes.

So is it true or false?

Well, I suspect that the phrase ‘zooming with your feet’ is not supposed to be taken literally. It’s meant to help push lazy photographers into actively thinking about their compositions and lens choices and not just over-relying on zoom lenses. Using different focal lengths to normal can help shake up your photography and produce unexpected results.

So is Scott being a little bit pedantic here? Yes, although he is fundamentally correct. You can’t ‘zoom with your feet’ because the effects are indeed different. However, that old advice does still ring true: if you think you’re close enough, get even closer!
