Autofocus out of focus blurry

What make and model camera? Which Sigma lens? Do you have autofocus turned on, both on the camera and the lens?

Use autofocus if you have a AF lens on it.

Usually you get a kit 18-55 AF lens that has a A/M switch on the side. The switch should be facing the A side so it's set on autofocus. Then you have 9 points on your viewfinder, those are the autofocus points. It should usually be set to center, because you usually want the object in center of your photo to not be blurry.
Remember to press the shutter button halfway and give some time for the autofocus to focus. Then you can press it all the way, you should have your photos nice and clear.

If you happen to have a manual focus lens, you should be watching through the viewfinder and turning the focus ring on the lens and determine if your object is in focus. It's hard at night, but get some practice at home when you have some more light so you get more familiar with the focus.

Hi, It wouldn't autofocus on the D5000 as the body doesn't have an auto focus motor in the body and since that lens is AF, not AF-S, it won't autofocus. It should autofocus on the D7000 though, how far away are you from the object you're trying to photograph?

Take your 200 to service.

Simplest answer is that you may have accidentally flipped the focus switch (A/M) on the lens to M. This turns off autofocus for that lens (which you might need to do if autofocus just can't resolve the image). Try turning it back to A.

Another possibility is that you're using an autofocus target different from the one you're expecting. The problem would be apparent regardless of lens choice, by being in focus in a different part of the image. You can press the arrow keys (while holding shutter release down halfway) to change AF targets, or change a menu setting to simply choose the closest target.

The shooting modes have no effect on focusing ability.

The camera would likely detect other focus-related problems (like servo failure).

hi there,

i think your lens calibration is not match as it default so the auto focus can`t determine the object sharply

you should contact your official service center to get it fixed

thanks

Next to the viewfinder ther is a diopter adjustment so you can change the focus in the viewfinder. this is so if you need glasses the camera can be set for you. Start by focusing the camera on something, then slide to turn the diopter adjustment until it looks sharp and try not to bump it.

The simplest thing which might have gone wrong is that you mistakenly activated the macro function. Try taking a picture of, say, a flower from a few inches: if it's sharp, you're employing the camera's macro function and need to deactivate it.

I don't recall the DSC having a manual focus setting, but check it out. If you turned it on, you need to manually adjust the focus through the zoom control in order to get sharp pictures (or turn on autofocus, of course).

Otherwise, the auto-focusing software might be at fault. There are several autofocus settings available; try cycling them all and see if the problem is reversible.

If not, either the autofocus parameters are gone awry - I'm afraid the camera'll need servicing - or maybe a dirty lens is causing the autofocus to malfunction, in which case cleaning it would solve the problem. Frankly, it's unlikely - it would take a really cleverly positioned and greasy fingerprint to fool a modern focusing engine. But you might be lucky, and it's worth a check.

Have you checked the autofocus? You may need to clean the front sensor. Hold shutter down half way to see if camera will autofocus, try this in several modes. Hold shutter half way down and look at screen, picture should come into focus. Make sure you do not have "Macro" selected

Try checking your settings for the type of shot you are taking and for the type of focus......
type of shot is the dial on the top, and then:
1) menu, metering
and also check your autofocus mode
2)menu, autofocus; try the single autofocus, it might be set to continual

Also, you could try updating the firmware in your camera. You do this through the Nikon website.
