Fujifilm X-T5 Background Blur: Aperture, Distance, Lenses

To blur the background on the Fujifilm X-T5, turn the shutter speed dial to A for Aperture Priority, then turn the lens aperture ring to its smallest f-number. After that, get closer to your subject, zoom to a longer focal length, and put more space between your subject and whatever is behind them.

That is the whole recipe. The rest of this guide explains each piece in plain words, so you know why it works and what to try when it does not work yet.

The four things that blur a background

Fujifilm's own bokeh guide says it is easy to create blur with an X Series camera once you use the right settings and adjust your technique a little. Bokeh is the word photographers use for that soft blur. Think of a portrait where the person is crisp and the trees behind them melt into smooth color.

Fujifilm's guide names four things that control how much blur you get: aperture, how close you focus, focal length, and how far the subject is from the background. Picture four volume knobs. Each one turns the blur up a little. Turn all four and the blur gets loud.

Lever	What to do	Why it helps
Aperture	Use the smallest f-number your lens allows	The widest aperture gives the shallowest depth of field
Focus distance	Move closer to your subject	At 6 feet you get more depth of field than at 3 feet, so the background looks sharper
Focal length	Zoom in or use a longer lens	18mm makes less blur than 90mm
Subject to background	Move your subject away from the wall or fence	A background farther behind the subject looks more blurred

Step 1: Put the X-T5 in Aperture Priority

Aperture is a hole inside your lens. It works like the pupil of your eye: it opens wide when it is dark and gets small when it is bright.

The size of that hole is written as an f-number. Here is the part that trips everyone up at first: a small number like f/2 means a big hole, and a big number like f/11 means a small hole. Small number, big hole, more blur. If that feels backwards, that is normal. It feels backwards to almost everyone at the start.

The X-T5 has three dials on top for ISO, shutter speed, and exposure compensation, and most XF lenses add an aperture ring, so you can check and change your exposure before you even turn the camera on. Fujifilm recommends Aperture Priority over Program mode for blur, because it lets you set the aperture to whatever you want with the lens ring. On X Series cameras without a separate mode dial, Fujifilm says you select Aperture Priority by choosing A on the shutter speed dial and setting the aperture on the lens.

1. Turn the shutter speed dial to A.
2. Turn the aperture ring on the lens to its smallest f-number.
3. Take a picture and look at the background on the screen.

If the dials are still new to you, the guide to the best Fujifilm camera settings for beginners walks through them one at a time.

If your lens has no aperture ring

Digital Camera World notes that you need Fujinon lenses with an aperture ring to get the full dial-driven experience, but you can control the aperture from the camera body with other lenses. The blur works exactly the same either way. Only the way you turn the knob changes.

Step 2: Get closer to your subject

Hold your finger close to your eyes and look at it. The room behind it goes soft. Now hold it at arm's length, and the room looks sharper. A camera works the same way.

Fujifilm's guide explains that if you frame a portrait at three feet and then at six feet with the same aperture, you get more depth of field at six feet, and the background looks more in focus. Depth of field is the slice of the scene that looks sharp. Think of a loaf of bread: a thin slice means only your subject is sharp, and a thick slice means lots of the scene is sharp. Fujifilm's sample pair was made on an X-T4 with the XF16-55mmF2.8 R LM WR lens at F4 and an equivalent focal length of 55mm, once at 3 feet and once at 6 feet.

So before you change any setting, try taking two steps toward your subject. It costs nothing.

Step 3: Use a longer focal length

Focal length is how zoomed in your lens is. A small number like 18mm sees a wide view. A bigger number like 90mm sees a narrow, close-up view.

Fujifilm's guide says shooting at 18mm produces less blur than shooting at a longer focal length like 90mm, so longer focal lengths help when you want plenty of blur. The guide also points out the catch: you need room to back up and still frame your subject, and still be able to talk to them if it is a portrait.

If you use a kit zoom, zoom toward the long end and step back to keep the same framing. One honest warning from the research: Digital Camera World found the XF 16-80mm f/4 often sold with the X-T5 is weak at the edges at its widest and longest settings, and not sharp at 80mm even in the center. If your subject looks soft at the very end of that zoom, back off a little and look again. That is not a mistake on your part. It is the lens telling you where its sweet spot is.

Step 4: Pull your subject away from the background

This tip has nothing to do with camera settings. Fujifilm's guide gives the example of a person standing two feet in front of a distracting fence: the fence may stay visible no matter what your settings are, but move the person farther from the fence and it looks more blurred. To keep the same framing and focus distance, you step back too.

Think of it like a stage. The farther the actor stands from the painted backdrop, the more that backdrop fades into a soft wash of color. Look for spots where there is open space behind your subject: a long hallway, a field, a street that stretches away.

Nail your focus, because the sharp slice gets thin

When you use a wide aperture and focus close, Fujifilm says you may have only a fraction of an inch in focus, which could mean just the subject's eye is sharp, or just the tip of a flower petal. That makes your focus method matter.

In the Q Menu you can choose Single Point, Zone, or Wide/Tracking, and Fujifilm describes Single Point as highly selective. For a still portrait or a flower, Single Point on the eye or the petal is a good place to start. The X-T5 also has subject detection for human faces and eyes, plus animals, birds, cars, motorcycles, bicycles, airplanes, and trains.

Reviewers have found limits worth knowing. In PetaPixel's review, the camera picked out a subject's eye even when the other eye was in deep shadow. The same reviewer found animal and bird detection rarely focused on the eye, and in side-by-side tests the hit rate on animals was around 50% on the X-T5 versus around 90% on the Sony a7R V. If you photograph pets at a wide aperture, put a single focus point right on the eye and take a few frames. A missed shot is just information about what to adjust next time.

Bright sun and wide apertures

Think of the shutter as a door that opens and closes to let light in. Fujifilm's guide explains that the wide apertures you use for blur let in lots of light, so the shutter speed has to rise to make a good exposure. In other words, the door has to open and close faster.

The X-T5's mechanical shutter reaches 1/8000 second, and its electronic shutter reaches 1/180,000 second. Fujifilm says that electronic shutter speed is about 2.5 stops faster than other X Series cameras and suggests using it with wide apertures in extremely bright environments. So on a sunny day, you can often keep the aperture wide instead of giving up your blur.

The flip side is worth knowing too. Digital Camera World noticed diffraction softening starting to appear as early as f/8 on the X-T5, possibly because of its high resolution. For blurry backgrounds you will be far from f/8 anyway, but it is a good reason not to stop down further than you need.

Lenses that make blur easier

Every tip above works with any lens, but Fujifilm's guide says picking the right lens from the start helps. Lenses with big maximum apertures are called fast lenses, because they let in lots of light and allow faster shutter speeds.

Lens (as described in the research)	Maximum aperture	What the source says
A versatile wide-angle lens in Fujifilm's bokeh guide	F1.4	Fast maximum aperture that gives lots of background blur
Fujifilm's widest-aperture X Series lens	F1.0	76mm equivalent focal length, described as a perfect portrait choice for the most subject separation
XF16-55mmF2.8 R LM WR	F2.8	Used at F4 in Fujifilm's 3 ft vs 6 ft example
Fujinon 18-55mm f/2.8-4 R LLM OIS	f/2.8-4	Offered as an X-T5 kit lens at launch
XF16-80mm f/4 R OIS WR	f/4	Offered as an X-T5 kit lens at launch; Digital Camera World found it soft at 80mm

Digital Camera World found the XF10-24mm f/4 has obvious weak spots on this camera and very soft edges at 24mm, and suggests better Fujifilm lenses if you want the best quality from the sensor. The guide to the best lenses for the Fujifilm X-T5 goes further on that.

Big, fast lenses can feel front-heavy. Fujifilm announced the MHG-XT5 grip to help you hand-hold the camera with a large-aperture lens mounted.

A note on macro lenses

Macro lenses focus very close, and focusing close is one of the four blur levers. Fujifilm warns that at close distances and wide apertures you may only get the tip of a petal sharp. In PetaPixel's hands-on, the writer mostly used a small 30mm macro lens on the X-T5. The research here does not compare the look of the blur from different macro lenses, so no ranking is offered. Start with the four levers and focus carefully on the one detail you care about most.

Video blur works the same way

The same four levers apply when you film. The X-T5 records 6.2K at 30p in 10-bit 4:2:2. To keep a moving person sharp against a soft background, Fujifilm says you can switch to AF-C with the focus mode selector and turn on face detection in the AF/MF SETTING menu. If you came here searching for a background blur button on Sony's ZV-E10 II, that camera has its own walkthrough: Sony ZV-E10 II Background Defocus Button.

When the blur still will not come

Run through this short checklist. Each line is one of the four levers.

• Is the shutter speed dial on A, and the aperture ring on its smallest number?
• Can you take two steps closer?
• Can you zoom in and step back to keep the framing?
• Can your subject move a few steps away from the wall, fence, or bush behind them?

Change one thing at a time and compare the pictures side by side. You will start to see which lever moves the blur the most in the places you shoot, and that is how this becomes second nature.
