Pick the Right Canon Lens for Your Professional Headshot

Start with the Classic 85mm Prime

If you only buy one lens for headshots, make it an 85mm prime. I’ve shot over 3,000 portraits with my Canon RF 85mm f/1.2, and the results are why it never leaves my bag. The focal length compresses the face just right—it flattens features slightly for a more flattering look than a wider lens. Your client’s nose won’t appear exaggerated. Their eyes will stay in perfect proportion to their ears. It’s a subtle optical correction that makes people look like the best version of themselves, instantly.

Shoot at f/2.8 on that lens. You’ll get a silky, blurry background—what we call “bokeh”—that makes your subject pop without turning their eyelashes into a soft mush. One client, a nervous software engineer, saw his first proof and said, “I look confident.” That was the lens, not him. He was slouching when he walked in.

Consider the Versatile 70-200mm f/2.8

Now, let’s talk about the workhorse: the 70-200mm f/2.8. This zoom lens is your secret weapon for dynamic sessions, especially if you’re in a small studio. You can stand in one spot and frame a tight headshot at 200mm, a three-quarter shot at 135mm, and an environmental portrait at 70mm without moving your light stands an inch. The flexibility saves you 15 minutes of setup time per client, minimum.

At 200mm and f/2.8, the compression is even more pronounced than the 85mm. It beautifully separates the subject from any background. But watch your distance. Stand too far back in a dim room, and you’ll fight with camera shake. My rule? Never shoot below 1/200th of a second with this lens, and keep your ISO as low as your light allows—800 or below if you can.

Try the 50mm f/1.8 for a Budget Option

Your wallet is talking, and I’m listening. The “nifty fifty,” the Canon EF or RF 50mm f/1.8, costs about $125 used. It’s a stunning value. For headshots, you must use it carefully. The 50mm focal length requires you to stand closer to your subject, which can introduce slight, unflattering distortion if you’re not careful. It will make a face look wider if you shoot from the wrong angle.

Here’s the fix: never shoot wider than f/2.8 on this lens for a professional headshot. At f/1.8, the depth of field is paper-thin; one eye will be sharp, the other will drift into blur. Step back. Use a longer focal length on your feet. Frame your subject from the chest up, not just the face. This forces you to create working distance. I’ve gotten portfolio shots with this lens that clients adore, but I had to work harder for them.

Avoid the Distortion of a 35mm Lens

I see this mistake every week. A photographer uses a 35mm lens for a headshot because they love the environmental context. What the client sees is a distorted face—a looming nose, a receding chin, widened features. It’s an honest optical effect, not a flaw in the lens, but it’s deeply unflattering for a corporate portrait. People hire you to look capable, not like a caricature.

Test it yourself. Take a picture of a friend at 35mm from three feet away. Now take one at 85mm from eight feet away, framing the same amount of their face. Put them side-by-side. The 35mm version will look like they gained ten pounds in the cheeks. Save the 35mm for full-body shots or when you want to show the lawyer in her massive book-lined office. For the face, it’s a hard no.

Set Your Aperture Between f/2.8 and f/5.6

Aperture is your control for sharpness and blur. It’s not about shooting “wide open” at f/1.2. That’s for art. For a professional headshot, you need the entire face in critical focus. Start at f/4. That’s your sweet spot. At f/4 on an 85mm lens, both eyes are razor sharp, the tip of the nose is defined, and the background is still a soft wash of color. It’s reliable.

Move to f/5.6 if you’re using a zoom like the 70-200mm or if your subject is angled, with one ear closer to the camera. The deeper depth of field ensures everything from the eyebrow to the far cheek is sharp. Only stop down to f/8 or further if you have a distracting background you can’t blur otherwise—like a busy plant behind them. Your priority is the person, not the technical showcase of your lens.

So, pick your focal length for the flattering compression, then set your aperture for sharpness. That’s the formula. Rent an 85mm for a weekend first if you’re unsure. Shoot the same person with a 50mm and an 85mm, both at f/4, and compare the files on your big screen. The right tool doesn’t just make your job easier; it gives your client a result they’ll use for years.
