Quick Tip: Be More Free with Only One Lens

Quick Tip: Be More Free with Only One Lens

We’re so used to having zoom lenses around that we forget how to live with only one lens, especially if it is a single focal length, known as a prime lens. Can it be done? I recently used a single lens for several days, and found the challenge rewarding. Try this yourself!

Back when people started using SLR film cameras, they would usually buy the camera with just one lens, a 50mm. For many people that would be the only lens they would use, sometimes for all their life.


The low level of light at rock concerts asks for a lens with a wide aperture, like the f/2.8 on the 40mm used here.

The “normal” lens, as it is considered, because it covers about the same field of view as human vision, was, then, enough for almost everything. Zoom lenses, when they first appeared, were generally considered second class optics. The usually had a lot of distortion and vignetting. And they were slow lenses meaning they didn’t let in much light.


Zooms Instead of Prime Lenses

With the advent of zooms of greater optical quality, cameras started to be sold with a zoom lens, usually covering from 28 to 70mm, and people forgot what it was to live with just a single normal lens.

Now, with digital cameras and APS-C sensors, a kit lens covers, usually, 18-55mm. That range, due to the crop factor in Canon cameras, for example, which is 1.6x, equals, to keep things simple, the coverage of a 28-88mm lens. So, not much has changed from the days of 35mm film, when it comes to the focal lengths used.


This can be considered a cat portrait. It was a snapshot taken without much support and done quickly, to register the cat stretching, his ears pointing towards the back, before the animal moved away.

If you ask your friend photographers if they could live with only a single focal length, they will probably say no. We’ve grown so accustomed to use zooms that we cannot envisage other ways to photograph.

But in fact, it is possible to take great photographs with a single lens, and it is a challenge you should take from time to time. Choosing just one lens and setting goals around its use will widen your vision when it comes to photography.


Zoom with Your Feet

The initial constraints it may cause will fade away soon, and you will end feeling more free, believe me. The simplicity the use of a single lens introduces, will set a new dynamic on your composition. You will discover that there is a way to zoom the lens, just walk towards or away from your subject.

We should remember Robert Capa’s advice: “If your picture isn’t good, get closer.”


A night shot, a long exposure that enters the realm of landscape photography too. Again, always the same lens.

I always think it’s fun to set goals and try to reach them, so when I recently got a new Canon EF 40mm f/2.8 STM Pancake to test with the new EOS 650D, I decided to use the lens for different situations and cover very distinctive subjects with it, to proof to myself it can be done.

I truly believe that leaving behind most of your gear and daring to go outside with a basic kit can help you to gain a new perspective on your photography. You may even find that you have a new lens that you’ll be using more and more.

The new 40mm lens from Canon is the smallest lens in their collection. It is even smaller than the converters used with Canon big professional lenses. Placed on the front of the camera, it creates a small package that you can take anywhere. It’s still bigger than a compact or mirrorless camera, but it’s a good “take anywhere” solution.

This 40mm pancake, which has a new technology for focusing, STM, a Stepper Motor for smooth and silent video auto focusing, can also be used for still photography and, being shorter than the “normal” 50mm f/1.8 from Canon (which becomes a 80mm on a small sensor), will give you a coverage around 64mm on an APS-C sensor. So I was curious to see what I could do with this kit.

People tend to associate different lenses with different subjects: a wide angle for landscape, a medium zoom for portrait, then a long lens for wildlife. But there’s really nothing that stops you from trying things different ways. For example, I use a focal length of 400mm (a 640mm crop on my APS-C) for most of my flower photography. I do think the images published here show that you can cover a lot of different subjects with just one lens.


A close up of flowers is one more of many different images, all taken with a single lens. Challenge yourself to do this. You’ll grow, photographically speaking.

One Lens, Multiple Visions

I took the lens to the first concert of my younger son’s rock band. It is a f/2.8 lens, so it did deliver me the pictures I was hoping to get. This is a good lens for low light photography. Although low light does not always mean working wide open. For the night shot outdoors I supported the camera on a tripod and exposed for 15 seconds at 1600 ISO, so I could get the dishes and the stars in the night sky behind them. Because the night was windy I decided to use a higher ISO to lower the exposure time.

Flowers are something that interests me, so I could not resist to do some close up work. The picture says it all, I think! For the family cat picture, which was a snapshot made hastily, I had to hold the camera steady because of the low speed and the awkward position I was in, but again, the result pleases me.

These four examples show the variety of subjects, from close distance to wide vistas, that can be covered with a single lens. Dare to try it yourself. Even if you do not own a single focal length lens, define a value from your zoom’s range and photograph everything with it. Do a one day project if you want, and study the results. I bet you will be surprised.

    Nice article, but APSC Canon cameras ship with an 18-55 EF-S, meaning it doesn’t get cropped.

    • Alex

      Mark, you are wrong.
      The field-of-view of the lens is equivalent to 29-88mm on full format cameras.

      Check the internet for some test sites (as this one for example: http://www.photozone.de)

    The lens that spends the most time on my camera is the AF-S Nikkor 35mm f1.8G DX. I have discovered that if I use a little imagination I can get an awful lot of mileage out of this single, “normal” focal length lens.

    I have some examples here:

    http://thephotophile.blogspot.se/2011/01/35mm-f18-as-portrait-lens.html

    I tried to put a big variety of different shots in there to show how versatile it can really be.

    I hope everybody tries this out for a while and gets to see how it makes their little grey cells work overtime to come up with something new and exciting from a single focal length. It will help you get better shots when you finally go back to a zoom lens too. Win win!

    I just went through this very problem last night when I went to my county fair. I started with my $125 canon 50mm f1.8 lens and had to work too much so i switched back over to my stupid kit lens. I need to leave that home next time. I never have any need for change when I use my medium format camera so I should have the same mentality with my dslr, right?

    I’ve been eyeballing that 40mm stm lens for about a month now. I want one.

    I was in St. Petersburg and had my 16-35mm stolen right off the camera body. The only other glass that I had was my 50mm. I used it for four weeks in The Baltic and Great Britain. It was a lesson indeed, although an expensive lesson. Given the choice of only one lens I would take the 50mm and use the digital zoom of my feet to get the shot!

    Zoom lenses are bulky.
    Fixed focal-length lenses are ideal.
    Don’t worry so much about DOF.
    Just keep shooting.

    I will take a trip to the zoo about once every 3 months, but will only take one lens with me, or two primes on two bodies……but it does make you think about all of the other “stuff”. Not just “I’m taking a picture of a tiger”, but “How am I going to frame this composition?” I find that the pictures are much more pleasing to me since I do less spray and pray photography like I used to with my super zooms.

    I bought the 40mm STM a couple of months ago. Love it! It’s sharp, very compact and feels like you’re only carrying body weight and size. I use it when I want to run around with next to nothing. I have a bag full of heavy Canon L glass, but this is a fun option!

    Here’s a grab shot on a very hot and humid day where I wouldn’t want to be carrying anything heavier. I was panting worse than this poor pooch, ha!

    I would have to disagree with the Zoom with Your Feet notion though. The beauty of a zoom is finding the proper placement of near and far objects, and zooming to crop to that placement. Moving camera placement alters perspective, zooming the lens doesn’t.

    Here’s a couple of illustrated pages that show images of what I’m trying to describe.

    I totally dig the ”use your feet to zoom”. It’s so much more involved. I always giggle at the idiots who zoom from far and struggle to get a clear frame as people are passing by. Muhahaha. Great post!

    I hate it when people say 50mm is the viewpoint of the eye. It isn’t. The reason why 50mm was/is so popular is because it’s so easy to make. That’s also why it’s cheaper. It’s a lens with simple optics. The focal length is alright, but it’s not special because it matches the eye, but because people have shot with it for so long (because of the reason stated above).
