Every photographer should learn to master portrait photography. Humans are one of the most fascinating subjects you could ever hope to find, and a beautiful portrait photo that perfectly captures a person’s personality and emotions is something that all photographers should know how to create. If you’re just starting out in photography and want to build a solid lens collection, it would be a good idea to invest in the best portrait lens that you can get.

Even if you have no plans on becoming a portrait photographer in the future, having a reliable, high-quality lens that can take great portrait photos is still an important investment to ensure that you have a good, well-rounded lineup of camera lenses.

But first, let’s define what a portrait lens really is.

What is a portrait lens?

A portrait lens is any lens that has the right focal length and aperture to take exceptional portrait photos. The term “portrait lens” does not refer to any specific type of lens—technically, any lens can be used for portraits. You can use a prime, a zoom, a telephoto, or even a kit lens. But ideally, the best portrait lenses are those that have a focal length of anywhere between 70 to 135mm, with a moderately wide maximum aperture for great low-light performance and a shallow depth-of-field.

What makes a good portrait lens?

There is no such thing as the “perfect” portrait lens. The right lens for your needs may not be the right lens for another photographer. If you’re looking for a good portrait lens that can give you the best results, you will have to consider a few factors:

  • What type of camera do you have? Full-frame or APS-C?
  • Where is your preferred portrait shooting location?
  • What type of portraits will you be shooting?
  • How much of the subject’s body will you be including in the photo?

Long Focal Length

Most portrait photographers prefer a short to moderate telephoto lens for shooting portrait work. Longer focal lengths are ideal because they allow the photographer to shoot a close-up photo of the subject despite standing a few feet away, yielding more realistic proportions. When there is a shorter distance between the lens and the subject, it can sometimes create distortion and make certain facial features appear wider or larger.

Therefore, if you’re looking for the best lens for portraits, get one that has a long focal length. Aim for a focal length of at least 70mm for APS-C cameras or 105mm for full-frame cameras for better portrait photos.

Of course this doesn’t mean that you can’t use something shorter for portrait work. Lenses with shorter focal lengths (at least 50mm for full-frame) can still be useful for portrait photography, particularly when you are shooting half-body or full-body portraits.

What Is the Best Focal Length for Portrait Photography?

A good portrait focal length is somewhere between 35mm and 200mm. It’s quite a broad range, but you understand why once you know what a portrait lens is. A portrait lens helps you capture your model’s best features, reveal their personalities and attitudes, and create visual stories, not just aesthetic photographs.

Therefore, choosing a portrait focal length depends on the model’s experience with cameras, posing, and décor. For example, if you want a close-up of a shy person, you need a longer focal length to give them space and help them relax. You need a shorter focal length if you want to localize the portrait and include background elements. That’s why the best portrait focal length is not a number but a range of possibilities.

Wide Aperture

As previously mentioned, a wide aperture creates a shallow depth-of-field. The wider the aperture of the lens, the shallower your depth-of-field becomes.

A maximum aperture of f/4 or larger will create a very shallow depth-of-field, resulting in a larger blurred area. This allows you to completely blur the background (and even parts of your subject) and ensure that your focal point—your subject—is the only part of the image that is tack-sharp. Should you choose to go with this type of aperture, make sure that the lens also excels at focus precision and accuracy. It is supremely important to nail your focus—otherwise, you may not get the results you want.

An aperture of f/8 or similar gives you a moderately shallow depth-of-field, which is less shallow than what you would get with f/4 or larger, but still shallow enough to provide a sense of separation between background and subject. It’s also large enough to allow you to use faster shutter speeds and keep your ISO low for less grain and noise. This type of aperture gives you the best of both worlds.

The best lens for portraits should have a maximum aperture of f/8 or larger. Anything smaller than that will result in a larger in-focus area, which is not necessarily a bad thing if you need to make other subjects in the photo appear sharp, such as a portrait with more than one subject. Do keep in mind, however, that smaller apertures may require slower shutter speeds and higher ISO for optimum exposure.

Prime or Zoom?

Most people will tell you that a prime lens is best, but honestly, you could go with either one. Primes typically make the best portrait lenses because they offer superior image quality and stunning bokeh. They are also faster, sharper, and yield less visible distortions and vignetting. But on the other hand, they are also pricier than zoom lenses and offer no flexibility—you’re stuck with just one focal length. Of course you can easily stand closer to “zoom in” or stand farther to “zoom out,” but this may not always be possible in certain situations.

If you need something that’s budget-friendly and allows for flexibility, zoom lenses also make good portrait lenses—particularly those that are optimized for portrait work and have rounded diaphragm blades like the Olympus 40-150mm f/4-5.6. Zooms are convenient and versatile because they allow you to choose between a wide range of focal lengths to suit your needs, plus they are relatively inexpensive compared to prime lenses.

Good Bokeh

Bokeh is defined as the quality of the blurred or out-of-focus parts of a particular image. A lot of photography enthusiasts are obsessed with bokeh, to the point where they’ve even come up with ways to digitally add it to their images using photo editing software. But the thing to remember is that not all bokeh is desirable. There’s good bokeh, and then there’s bad bokeh.

Bokeh is in the eye of the beholder—which is why most photographers argue that there is no such thing as “bad” bokeh. Nonetheless, other photographers can differentiate the two because to them, good bokeh makes the image more pleasing to the eye, whereas bad bokeh can mean too much texture in the background and take focus away from the subject.

Take this image for example:

It’s a beautiful portrait, but some may argue that the bokeh in the background is too pronounced and distracts from the subject. But for other photographers, this type of bokeh is highly desirable in a photo.

Whatever your preference, make sure to get a lens that can give you the type of bokeh you want to see in your portrait photos.

Keep in mind that the best lenses that offer good bokeh are those with large maximum apertures, circular diaphragm blades, and lens coatings for reduced spherical aberrations.

How to Choose the Best Portrait Lens

How you choose a lens for photographing portraits is more complicated. The choice of a portrait lens depends on the type of portraits you photograph and your workflow.

For example, if you use the same photo set up all the time (e.g., corporate headshots, studio family portraits, etc.), you probably need a prime lens with the optimal focal length for your work. When photographing regular people, you should consider camera-shyness and choose a longer focal length. But for fashion and beauty portraits, you may want to be more adventurous and try a broader spectrum of lenses. For fine art portraiture, the sky is the limit.

Often, a portrait lens has a focal length that creates a natural perspective close to what the human eye perceives. However, it may also be a zoom lens that provides a range of focal lengths from wide-angle to telephoto.
