Prime Lenses

The first lenses ever to be sold were prime lenses. But that doesn’t mean they’re outdated. Prime lenses are still popular today, both among the stars of the photographic world and among enthusiasts. Prime lenses do bring special challenges, but these are easy to overcome. And your reward for using them will be high-quality, sharp, and high-contrast photos.

The greatest advantage of prime lenses is their optical quality. That is, the quality of their images—their contrast and their bokeh (those magical blurred backgrounds). Prime-lens pictures will hardly need any post-editing. These lenses achieve their high quality by having few moving parts. As an overall rule in optics, the more moving parts (such as a transfocator, optical stabilization, or even a badly manufactured case), the lower the image quality.

Fixed lenses are known for their high image quality.

These Lenses Are Fast

Another advantage of prime lenses is that they are very fast lenses. Normal lenses let you go down to about F 1.8 for wide and medium lenses (although you’ll also find values like F1.4, F1.2, and even F0.95—but only at very high prices.) The higher the focal length, the higher the minimum F-stop.

Example: normally lenses with transfocators (i.e. with a zoom) go to a focal length of 400 mm (e.g. the Canon 100-400 mm lens, which has a lens speed of 5.6). Meanwhile, prime 400 mm lenses have lens speeds of up to F2.8. And that’s a major difference.

Since prime lenses are fast lenses, you can keep taking pictures even in bad lighting conditions. But note that a prime lens may not have a built-in optical stabilizer. Stabilizers are only added to telephoto lenses, but these are their own special prime-lens category.

Fixed lenses are typically very fast lenses.

What They Lack

Too much praise looks suspicious, so let’s look at some downsides of these lenses. The biggest one is that they’re not universal. If you want to do real photography with prime lenses, you’ll need several of them. That means you’ll be paying more for your overall photo kit.

Also, prime-lens photography is not for beginners. It demands you be an ace at using your camera’s manual or semi-automatic mode, so you can get the most out of your lenses. It also demands that you know your composition. It can take some time to get used to zooming in or out using your feet, and not using the vastly-more-convenient lens ring.

Mirrorless Cameras

Mirrorless cameras are worth a mention here. These cameras are mainly intended for travelers and advanced amateurs. Their biggest disadvantage is that so far, they have a poor lens selection. Fujifilm offers a few lenses, but they are all prime lenses. So have a good idea in advance of what you want to photograph, and how. Olympus as well offers a line of prime lenses for its mirrorless cameras.

If you’re serious about photography, then don’t be scared of prime lenses. They’re demanding, but they’ll bring you better pictures, and you’ll be a more confident photographer. They’ll also teach you where to stand to get the shot you want. That way you won’t waste time zooming—you’ll just compose, sharpen, and shoot.

A Little History in Closing

Great photographers generally shoot with prime lenses. I’ll mention just one name here that’s forever tied to one camera and one lens. That name is Heny Cartier-Bresson. Bresson always used a Leica with a 50 mm lens.

I’ve been taking pictures since 2004. When I was starting out, I photographed almost everything. Later my style solidified and I began photographing people almost exclusively. At the moment my main genres are fashion and advertising.

    When I studdied photography in the 1950s Cartier-Bresson was my god (LSPGA)

    In the late 1960’s, I had a Pentax Spotmatic (yes, that’s long ago – does anybody remember that ?) with 3 fixed lenses and accessories (M42 mount !). Now, a few weeks ago, i bought a 35 mm F1,8 (that makes more or less a 50 mm on my Nikon). It’s quite different to ‘work’ again with such a lens. Kind of a new challenge !

      I also used a Pentax Spotmatic, from 1970 until today (it still works fine), originally with only a 55mm F1.8 prime, later I got a 135 telephoto and a 28mm wide angle. Those same lenses work well today on a Sony NEX mirrorless camera with a simple adapter, and also on a Pentax DSLR (with image stabilization built into the camera).

  • Most new Olympus cameras are now mirror-less and have a large selection of lenses. Also they have the stabilization built-in…

  • TerryB

    Just a small comment. These lenses should properly be designated as “primes”. A fixed lens is more appropriate to one that is permanently attached to the camera body and is not removable.

    The Sony Nex E mount is the best served for these prime lenses as there is an adapter for virtually any make of 35mm camera lens mount available.

  • Gordon Seifert

    Some manufacturers mirrorless cameras may have a limited range of lenses available, but the M43 platform (Lumix and Olympus) is not so afflicted. There are many lenses available and they are of very high quality as well. M43 fixed focal length lenses are referred to as ‘Primes’. In the case of Olympus none incorporate stabilization since stabilization is in the camera body. Some Lumix lenses do include stabilization, but not all.
