Years ago, professional photographers switched to using zooms for nearly everything, except for specialized work like macrophotography. Despite that, it is almost universally believed by amateurs on photo forums that using zooms is lazy and that 'real photographer' don't use zooms. They use single focal-length lenses and adjust the composition of their images by "Zooming With Their Feet." That is, they walk closer or further from the subject to adjust the size of the subject in the image.
Of course zooms are not made for many types of cameras (like rangefinders), so instead of a zoom, you would carry a selection of single focal length lenses. A popular idea on RFF is that you should carry only one lens, taking the "Zoom With Your Feet" concept to its most extreme.
The problem with only using one lens and "Zooming With Your Feet" is that the place you stand when you photograph does much more than establish the size of the subject in the image. It affects relationships between the subject and the background and foreground. By carrying only one lens focal length, you're constraining yourself to the point of making many photographs impossible. Here are some examples:
Consider this photograph of my house. There is a large tree in my neighbor's back yard, and it is mostly hidden by my house. I say "Mostly" because some of that tree's branches are visible, sticking out from the side of my house's roof on the left side of the photo. They're ugly and distracting. If I were using a single lens, I'd be stuck with it.
For this photograph, I moved closer to the house, making the tree branches disappear behind the house. To maintain a similar subject size, I set the zoom lens I was using to a shorter (wider angle) focal length.
Here's another example. This is another house in my neighborhood in Fort Wayne. Look at the right side of the image, and you can see a small part of the garage (and the car parked in front of it) sticking out from the side of the house. The garage is not attached to the house, it sits behind and to one side of the house. That little bit of the garage and the car are distracting and ugly. If I had only one single focal-length lens with me, I'd be unable to make a better picture.
As I did in the photograph of my house, I was able to remove the distracting background element by moving closer to the house. Once again, I zoomed out to a shorter, wider-angle, focal-length lens in order to maintain a similar subject size in the image.
These examples were made with a digital camera with a zoom lens (Olympus OM-D E-M1 mark II with the 12-40mm f2.8 Olympus Pro lens), but the conclusions are just as valid with film. You don't even need a zoom lens. When I shoot with my Leicas, I carry 21mm, 28mm, 35mm, 50mm, 90mm, and 135mm lenses so that I can choose the one closest to what is needed to get the composition with the subject/foreground/background relationships I want.
The right way to work is NOT to chose a lens then walk back and forth to get the composition. The right way is to find the place to stand that gives you places the subject and other elements in the image in the right places, then choose the lens (or zoom setting if you use a zoom) that will work to get the composition you want from that camera position!
