Why is my Nikon always out of focus?

I have a Nikon d3000… And when I pay so much for a camera I expect it to produce good pictures.
However I have to lensens, but they have problems focusing.
Problem nr 2 is that the pictures don't produce details. (Quite blurry) I swear, my nokia camera is better for macro. Why is this? I have a tripod so movement is not the problem.

Any ideas?

See that you're not using very low resolution files

If all your lens are producing blurry or out of focus photos, first make sure that you are not set to "M" manual mode, if you are and you want to use "Manual" be sure your shutter speed is above 1/60th. If you are using the "A" Auto or "P" Program modes and you are still having issues, its possible that your camera may have a miss aligned mirror or shutter mechanism and will require servicing from NIKON. Give them a call 1-800-Nikon-US (1-800-645-6687)

Are these lenses autofocus or manual focus? Even if autofocus, do you focus on something before taking the shot?

Get with a friend or with someone at a REAL photography store and let them try using the camera. If someone experienced gets photos that are fine, then the problem is obviously the user, meaning you, which I strongly think is the problem anyway.

Are you just letting the camera auto focus where it wants? Or are YOU in control of the FOCUS POINT so the camera will focus precisely where it should?

Are you trying to handhold the camera in dim light / low shutter speed conditions? This will cause blur.

Are you half pressing the shutter button to set focus before fully pressing the button to take the photo?

Are you trying to take a photo too close to the subject and thus too close for the lens to focus? You need a proper macro lens for macro photography. Without it, your Nokia probably is better than the Nikon.

In 99% of cases like this, the problem is the user, not the camera. Again, let someone who knows their way around a camera try it and see what happens.

This is a common problem.

I think 90% of photographers that switch from a point and shoot to a DSLR, are going to see a major loss in the quality for their images. That is because DSLR's lack a lot of the automatic functions that a point and shoot does, and it requires a lot more user input.

As far as focussing problems, there are two main causes:

1) If you are using AF make sure it is turned on. There's a switch on the lens. Them make sure you have set the correct AF point in the viewfinder. Refer to your camera's manual.

2) If you are using MF, make sure the viewfinder diopter is set correctly.

If everything is out of focus, either your lens is not attached correctly, it is damaged, or the problem is with shutter speed being to slow and is unrelated to focus.

Without having examples to look at, all I can say is that problems like this are generally 99% user error.

99% of the time it is down to the software behind the camera not the camera itself.

Well, there's your problem… U r expecting the camera 2 produce good pictures. Your camera knows better (it's just a camera, after all) & is expecting u 2 have some input & influence the final product.

Long story short, Auto + cheap glass = no bueno. You gotta learn how 2 use your camera right if you wanna get good pics w/ it.

Your camera is not producing good photographs either because it is faulty, or because you are doing something wrong. You are not getting precise answers because you are not showing any links to examples, nor are you explaining exactly what you are doing. On this evidence, my guess is that you are doing something wrong. It doesn't matter how much you paid for the camera, if you don't use it properly you will get bad results.
