Why won’t my Canon 800D take a photo in low light?

My Canon 800D sometimes won’t release the shutter in very dark scenes, such as early-morning landscapes. The camera appears to try to focus, fail, and then refuse to capture the image. I’ve seen this in different shooting modes, and with both the 18-55mm kit lens and a 70-200mm f/2.8 lens. Is this normal behavior, and is it caused by a setting or by the camera itself?

If your camera refuses to take the photo, it's usually because you have set it to AF + One shot mode. In such situation it needs to lock on the subject and you can see it struggling by flashing red light instead of a solid red (with a beep).
To get around this, you either need to focus manually or use some kind of external lighting (flash, lamp, whatever) to help the camera to achieve focus.

Yes—this is normal if the camera is using autofocus in One Shot AF. In that mode, the 800D is set to prioritize focus confirmation before it will fire the shutter. In very dark scenes, autofocus may not be able to lock, so the camera keeps trying and then won’t take the photo.
What to do:
- Switch to manual focus if autofocus can’t lock.
- Add light or aim at a higher-contrast area so AF can find focus.
- If available, use an external light source to help the camera focus.
So this is usually a focus-setting behavior, not a fault with the camera model or lens.
