Choosing lenses for studio portraits and product photography

The lens decision is the one new shooters overthink and seasoned shooters make in a second — because once you understand what focal length and aperture actually *do*, the choice falls out of the shot you're trying to make. This is a working guide to picking glass for the two things a studio shoots most: people and products. No spec-sheet worship; just which lens for which job, and why. Every lens named here is one we rent, so you can read it, then book it.

The two dials that decide the look

Before any specific lens, internalize what the two big choices control. They're not interchangeable, and most beginner mistakes come from reaching for aperture when the answer is focal length, or vice versa.

The single most useful idea here: perspective comes from where you stand, not from the lens. A longer focal length lets you stand farther back to fill the same frame, and that distance is what flattens features and compresses the background into a creamy fall-off; a wide lens forces you in close and exaggerates whatever's nearest the camera — dramatic, but unkind to a face. Aperture is a separate lever: it sets how thin the plane of focus is and how much light you collect. Keep the two straight and the rest is easy.

Portrait focal lengths: 50mm vs 85mm

For people, our portrait workhorses are the fast 50mm and 85mm primes — the RF versions for the Canon EOS R5, and the Nikon Z equivalents for Z-mount bodies. Reach for the 50mm when you want context and proximity; reach for the 85mm when you want flattery and separation.

The headshot: 85mm

For a head-and-shoulders headshot, 85mm is the default for a reason. It lets you stand back far enough that the face renders in natural proportion — no enlarged nose, no stretched forehead — while the background compresses into a clean, soft field behind the subject. A fast 85mm (we rent the RF 85mm f/1.2) wide open isolates a single face beautifully; in practice you'll often stop down a little so both eyes on a three-quarter turn stay sharp. If 85mm puts you too far back for the room, a 50mm at a tighter crop is the fallback.

Full-length & environmental: 50mm

When you need the whole person, or the person plus their space, the 50mm earns its keep. At 85mm a full-length frame demands a lot of floor between you and the subject — sometimes more than the set allows — whereas a 50mm gives you a natural perspective at a manageable distance, with enough environment in frame to tell a story. It's the right call for fashion full-lengths, lifestyle, and environmental portraits where the room is part of the picture.

Beauty & detail: 85mm, or step to a 100mm macro

Beauty work — tight on the eyes, the lips, the skin — wants compression and resolving power. The 85mm covers most of it. When the brief gets truly close (lashes, a lip texture, a jewelry-on-skin detail), step to the RF 100mm f/2.8 L Macro, which focuses far closer than a portrait prime and even carries an adjustable Spherical Aberration ring to soften or shape the bokeh for a dreamier beauty look. The longer 100mm length also lets you keep a comfortable working distance from the talent while filling the frame with detail.

Aperture for portraits: how wide is too wide?

An f/1.2 or f/1.8 lens is a tool, not a default setting. Wide open, the plane of focus is so thin that on a three-quarter turn you can have the near eye sharp and the far eye already soft — striking for a single hero frame, frustrating when the client wanted both eyes crisp. A few rules of thumb from the studio floor:

• Single subject, hero frame: f/1.2–f/2 for maximum separation — commit to the near eye and let the rest fall away.
• Standard headshot, both eyes sharp: f/2.8–f/4 gives you a usable depth of field across the face on a turn.
• Groups or full-length: f/5.6–f/8 to keep multiple people, or a whole figure, in focus front to back.
• Remember you're lit: in the studio you control the light, so you can stop down for depth without starving the exposure — open up for *look*, not because you have to.

Product & tabletop: macro is the workhorse

Product photography rewards different priorities than portraiture: front-to-back sharpness, true close-up reproduction, and working distance that keeps the lens (and your light) out of the product's reflection. Two lenses we rent anchor this work.

RF 100mm f/2.8 L Macro — the everyday product lens

For most tabletop, packaging, food, and detail work on the R5, the RF 100mm Macro is the tool. It reproduces small subjects at up to 1.4× magnification — past the traditional 1:1 macro standard — so it fills the frame with tiny details, and its longer focal length gives you a comfortable distance from the product (useful for lighting around reflective surfaces). It carries optical stabilization for handheld detail work, though for serious product you'll be on a tripod, tethered, anyway.

Schneider 120mm LS Macro — when the file has to be flawless

Step up to medium format and the Schneider Kreuznach 120mm LS Macro for the Phase One XF is the luxury-product standard — a true macro on a high-resolution back. Because it's a leaf-shutter LS lens, it syncs flash far faster than a focal-plane camera, letting you freeze a pour or control ambient against your strobes on a built set. It's the lens for jewelry, cosmetics, watches, and anything where the file will be enlarged and scrutinized.

Aperture for product: stop down for depth

Product work usually wants more in focus, not less. At macro distances depth of field is razor-thin even at moderate apertures, so you'll often shoot f/8–f/16 to carry a whole object front to back — and where a single frame can't hold focus across a deep subject, focus stacking (several frames at different focus points, blended in post) is the standard answer. Because you're working with controlled light, stopping down costs you nothing but a little more flash power.

How it fits a studio workflow

In a controlled room, lens choice and lighting work together — and the cleaner you nail focal length and aperture in-camera, the less you fix in post. A practical day in our studio usually means starting on the 85mm (or 50mm) for portraits, switching to the 100mm Macro for detail and product crops, and shooting tethered to a big screen so you can confirm focus and reflections live. Because the room is lit and controlled, you're free to choose aperture for the look rather than for the exposure — and renting body and glass together means you carry exactly the focal lengths the shot list calls for, and nothing you don't.

When to rent it instead of buying

Most shooters don't need to own every focal length — they need the right one for the job in front of them. Renting glass per-project is how you match the lens to the shot without a closet full of specialized primes:

• Match the lens to the brief — take the 85mm for a portrait day, the 100mm Macro for a product table, and skip whatever the shot list doesn't need.
• The job pays for the glass — bill the rental to the production and return it when you wrap.
• Specialized lenses, occasional use — a true macro or a medium-format LS lens earns its cost on the shoots that need it, not sitting on a shelf.
• You're already booking the room — add the exact lenses to a studio booking and walk in with the right kit.

We rent the portrait primes (50mm and 85mm), the RF 100mm Macro, and the Schneider 120mm LS Macro alongside the bodies they mount on, so you can assemble a portrait-and-product package tuned to your shot list from one place. Pair the glass with the studio and a tether station, and shoot it lit and controlled.
