Try pressing the AE-L button on the camera (it is located around where your right thumb rests). If the camera focuses, this means that your neighbour probably assigned that button to act as AF-ON and forgot to tell you. This is useful in certain situations when you want to decouple the focus from the shutter button and in this case, pressing the shutter ...

I have Nikon D5200 and had similar issue where it would auto-focus in 'live view mode' when shutter release button was pressed half-way but not in 'view finder mode'. Later found that I had assigned function key (Fn) to AF-C and it would only auto-focus by pressing function key (Fn) in 'viewfinder mode'.

Try different lens on your cam, see if problem is with your lens or cam. If all lens shows same result then go to your setting and check if rangefinder is set to OFF, if it is set to OFF turn it ON.

With most Nikon cameras and AF lenses with focus motors in the lens, there are switches on both the lens and the camera that must be turned on for AF to be enabled. If there's not a physical switch on the camera (usually in the area near the lens release button that must be pressed to remove the lens), then it is probably buried somewhere in the menu. If ...

It could be several issues, but my first guess, since the FZ1000 is a superzoom bridge camera, is simply that when you zoomed in on your wife's face, you may have inadvertently moved the minimum focus distance of the lens past her. If you're not in macro mode, at the wide end of the lens (zoomed all the way in) you can focus as close as 11.8"/30cm, but ...

Switch the camera to using a single auto-focus spot in the middle of the frame. Most high end cameras have this capability. I don't know if your Sony camera can do that or how it will show you the spot if it does, but look around the owners manual. On my Nikon, the autofocus spots are shown as small red rectangles in the viewfinder. You point the spot at ...

Bird photography is the kind of situation where you have to select one of the auto-focus point (usually the center one). With such setting, you have a better control where the focus is done (as the camera will not switch between the focus-points). Furthermore you do not really care if the subject is right in the center of the image as, most of the time, you ...

You need to disable exposure simulation. The EOS M doesn't have a menu option for this but it is disabled with an ETTL flash or ETTL trigger in the hotshoe. (actually any Canon "dedicated" flash will also communicate with the camera and disable Exp Sim) You could also install Magic Lantern as it includes a menu option to disable Exp Sim.

As pointed by StephenG, you cannot always in a single shot focus on multiple different points, especially if they are at significantly different distances from the camera. You can adjust depth of field (with the associated drawbacks to maintain exposure), but this has its limits. What you can do, however, is take multiple pictures of the same scene, with ...

You cannot choose multiple points to have in focus at the same time in a shot. You can let the camera choose which one of several points it will use as a focus point in the shot, but the camera will not make any attempt to get all the points in focus - just one. You have limited control over how much of a scene around a selected single focus point will be ...

The target is under illuminated and underexposed. If the jpeg was generated in-camera the camera probably applied fairly aggressive noise reduction to the image. This will reduce the acutance of the image. If you haven't already, put the camera on a stable platform, such as a tripod. Use base ISO and expose for as long as necessary to properly expose the ...

The focus looks nearly if not completely spot-on on my monitor, though try leveling the focus chart (you can see it's slightly tilted, which will throw off your measurements). You are more likely to be seeing the effect of spherical aberration in the lens, which manifests as a "glow" even on in-focus parts of the image. That this is common in all fast ...

Which focus mode have you selected in camera settings? The in-camera settings for focus modes also allow you to turn off autofocus without changing the focus button on lens. Check to see if you accidentally set this to manual.

After some more testing, it seems that high contrast areas can affect the PDAF, even if they are far away from the selected autofocus point. However, even in the very best conditions (flat, high contrast target on a flat, uniformly colored surface), some inaccuracy remains. I also tried a different EOS 750D with the same results, so it seems unlikely that ...
