Canon R5 Mark II Blurry Photos: Causes and Settings That Fix Them

Most blurry photos from a Canon EOS R5 Mark II come from one of three things: something moved while the shutter was open, the focus landed in the wrong spot, or the sharp zone was too thin. The fix is almost always a faster shutter speed, a better autofocus setup, or a slightly smaller aperture, and you can learn all three today.

If you are seeing soft pictures, please do not feel bad. Every photographer has a folder full of blurry shots. Each one is a clue, and once you learn to read the clue, the fix gets easy.

Step one: read the blur before you change anything

Blur is like a footprint. It tells you what happened. Before you touch a single setting, open the photo and look closely.

• Everything is smeared, even things that were not moving. The camera moved. This is called camera shake.
• The background is sharp but your subject is smeared. Your subject moved faster than your shutter could freeze it.
• Something is sharp, just not the thing you wanted. Focus landed in the wrong place, for example on a tree behind your friend instead of on your friend's eyes.
• The eyes are sharp but the nose or ears are soft. Your depth of field was too thin. Think of it like a slice of bread: sometimes the sharp slice is very thin.

There is one more thing to keep in mind. The R5 Mark II makes 45-megapixel images that measure 8,192 x 5,464 pixels. Zooming in to 100 percent on a file that big is like looking through a magnifying glass. Check your photo at a normal viewing size too, such as filling your laptop screen, before you decide it is ruined.

Cause 1: your shutter speed is too slow (camera shake)

The shutter speed is like a door opening and closing. While the door is open, light pours in. If your hands wiggle while the door is open, the picture wiggles too.

A fast shutter speed is a door that slams shut quickly. A slow shutter speed is a door that drifts closed. The longer the door is open, the more chance for blur.

What helps

The R5 Mark II has IBIS, and PetaPixel's first look describes it as a good IBIS unit. You can picture IBIS as a tiny pair of steady hands inside the camera, smoothing out your small wobbles.

IBIS has a limit, though. It steadies the camera. It does not steady your subject. A sleeping cat will come out sharp at a slow speed, but a running cat will not.

The fix

• Switch to shutter priority mode. You choose the shutter speed, and the camera picks the rest.
• If everything is smeared, double your shutter speed and take the shot again. Keep doubling until the blur goes away.
• Hold the camera with both hands, tuck your elbows in, and press the shutter button gently instead of stabbing it.
• If the photo gets too dark at a faster shutter speed, raise your ISO a little. A bit of grain is much easier to live with than blur.

Cause 2: your subject moved

Kids, pets, birds and athletes do not hold still for you. If the background is sharp but your subject is a smear, your door stayed open while they moved.

The fix

First, use a faster shutter speed than you would for a still subject. Then let the camera help you catch the moment.

The R5 Mark II can shoot 45-megapixel RAW images with full autofocus at up to 30 frames per second. That is like taking 30 pictures in one second, so one of them is likely to land at the perfect moment.

It also has Pre-Burst shooting, which PetaPixel describes as capturing the half-second right before you press the shutter. Think of it as the camera already watching and remembering, so you do not miss the jump because your finger was a little late.

The viewfinder helps you follow action too. PetaPixel reports the EVF promises blackout-free shooting when you use the electronic shutter. That means the view does not flash black between frames, so you can keep your subject in the frame more easily.

Bursts do have limits. In PetaPixel's early testing, the camera could keep going for roughly 10 seconds at 12 frames per second, but slowed down after around three seconds at 30 frames per second. Shoot short bursts around the moment instead of holding the button down the whole time.

Cause 3: focus landed in the wrong place

If part of the photo is sharp, but it is the wrong part, the camera focused on something you did not choose. This is a setup problem, not a broken camera.

Let subject detection do the work

The R5 Mark II uses Canon's Dual Pixel CMOS AF, which PetaPixel says has gotten significantly better on this model. It has AI-powered subject detection, including four specific animal types: dogs, cats, birds and horses. It also has eye detection that works alongside the animal detection.

Here is a simple example. If you are photographing your dog and subject detection is set to animals, the camera looks for your dog's eye and holds focus there, instead of grabbing the fence behind him.

The camera can also hold focus on your chosen subject even if another object briefly passes in front of it, according to PetaPixel's underwater review. In their tests, they found it easier to keep focus on one subject while sea lions swam past the camera. On land, that might be a player running behind a referee.

Learn the new autofocus menu slowly

PetaPixel notes that the R5 Mark II has the same simplified autofocus menu as the EOS R1, and that it takes some getting used to. If you are coming from an older Canon, give yourself a few practice sessions. Set one option, take some test shots in your backyard, and look at the results before changing the next one.

If you use Eye Control AF

Eye Control AF lets you look at a spot in the viewfinder and have the camera focus there. It has to be calibrated to your eye first. PetaPixel found it worked very well for some testers, but one staff member could not get it to calibrate properly, and they said this seems pretty common with some users.

If your focus keeps jumping to odd places, Eye Control AF may be guessing wrong. Recalibrate it. If that still does not help, turn it off and move your focus point with the joystick or the touchscreen. That is not giving up. It is choosing the tool that works for your eyes.

Check your lens

You can adapt older EF lenses to the R5 Mark II, but PetaPixel notes that many photographers prefer native RF lenses because autofocus performance can noticeably suffer with adapted glass. If an adapted lens keeps missing focus on moving subjects, try the same scene with an RF lens before blaming the camera.

Cause 4: your depth of field is too thin

The aperture works like the pupil of your eye. A wide pupil, such as f/1.8, lets in lots of light but makes the sharp zone very thin. A small pupil, such as f/8, lets in less light but makes the sharp zone much deeper.

If the eye is sharp but the tip of the nose is soft, your aperture was wide open and the sharp slice was thinner than your subject's face.

The fix

• Switch to aperture priority mode so you choose the f-number and the camera handles the shutter speed.
• Close the aperture a few steps, for example from f/1.8 to f/4, for portraits where you want the whole face sharp.
• For groups, close it further so people in the back row stay sharp too.
• Watch your shutter speed as you close the aperture. Less light can mean a slower shutter, which brings back Cause 1.

You can see this idea in the sample photos from PetaPixel's underwater review. A hooded nudibranch was shot at f/22, 1/160 and ISO 100 with dual strobes. A juvenile wolf eel was shot at f/25, 1/160 and ISO 200. Those tiny apertures give a deep sharp zone, and the strobes supply the light that a small aperture holds back.

If your goal is the opposite, a soft background behind a sharp subject, that is a different skill. Canon R6 Mark II: How to Get a Blurry Background walks through it.

Not blur, but it can look wrong: the electronic shutter

Sometimes a photo is not soft but looks bent or grainy. The shutter type can play a part.

The R5 Mark II has a stacked, backside-illuminated sensor, and PetaPixel measured its readout speed at approximately 1/125th of a second. Canon's stacked design promises reduced rolling shutter compared with the original R5. Rolling shutter is when a fast-moving object looks bent, like a golf club that seems to curve. It is not focus blur, so changing your focus settings will not fix it.

The fastest burst speeds require the electronic shutter, and DPReview's testing found that this shutter mode comes with "an appreciable noise cost". In Photons to Photos testing, the R5 Mark II's peak dynamic range was 11.45 with the mechanical shutter and dropped to 10.92 with the electronic shutter.

A simple rule for you: use the mechanical shutter for still subjects like portraits and landscapes, and switch to the electronic shutter when you truly need the speed.

A note on AI upscaling and denoising

The R5 Mark II includes in-camera AI upscaling and denoising. The upscaling can push 45-megapixel files up to 179 megapixels, and it only applies to JPEG files. These tools are helpful for other jobs, but do not count on them to rescue a photo that was blurry from motion or missed focus. Get it sharp in the camera first.

A starting checklist when your photos are blurry

What you see	Likely cause	What to try first
Everything is smeared	Camera shake	Shutter priority, double the shutter speed, hold the camera steadier
Background sharp, subject smeared	Subject moved	Faster shutter speed, short bursts, Pre-Burst for split-second moments
Wrong thing is sharp	Focus in the wrong place	Turn on subject and eye detection, check Eye Control AF calibration, move the focus point yourself
Eyes sharp, nose or ears soft	Depth of field too thin	Aperture priority, close the aperture a few steps
Fast objects look bent	Rolling shutter	Use the mechanical shutter if you do not need top burst speed

Practice turns blurry shots into sharp ones

Here is a small practice plan for this week. Pick one cause at a time. Spend one session on shutter speed with a moving subject, one on autofocus with your pet or a friend, and one on aperture with a portrait. Look at every result, sharp or soft, and ask what it is telling you.

The blurry ones are not failures. They are the photos that teach you the most. If you also shoot with an R6 Mark II, the same thinking applies, and Canon R6 Mark II Blurry Photos: 7 Causes and How to Fix Them has more for that camera.
