I'm having problems with I focus the camera out. It becomes burrie

AF=Auto Focus. With an autofusu capable body, the camera will automatically focus for you using preset focusing zone. Move the Switch to:
MF and it becomes a manual focus lens, where the photographer has to manually focus on his subject.

Performance wise, the camera has a couple of niggles. Start up to first shot time is around a second, and shot to shot (without flash) is good with three shots (the top three or the last three in a sequence are captured) in around 1.5 seconds unless the camera needs to refocus ort the flash fires. Flash recharge is around five seconds and disappointingly, the camera locks up as the flash charges, which is a shame.

But, focusing becomes an issue in low light too, where the camera will hunt trying to key on the subject or just continually fail to focus. So, beware in low light. There was another focus niggle on smaller subjects in macro mode where the camera would simply refuse to focus on anything in the frame smaller than the central AF area, and no matter what you do. Thanks

There are basically 2 adjustment can be made to focus your webcam, 1st is by the webcam software, try to search in the software any feature that can focus your webcam. The 2nd is the mechanical adjustment on the webcam itself, try to rotate the focus ring (webcam's eye) and see how the picture improvement.

Digital cameras require lots of power. Bad electrical contacts can cause lots of problems so battery and camera contacts must be cleaned properly. Batteries may be fully charged, but will be viewed as low if contacts are not really good. The LCD screen is a low steady load, but when lens extension, optical zoom, focus, and flash charging are added in the capture mode; the load is very heavy. Bad contacts make cameras do strange things like making bad pictures or shutting off with the lens out.
Do not overcharge.
Reset by removing power up to one month is the ultimate non-physical repair for DVD recorders and other software using digital devices. Digital cameras reset to original settings if batteries are removed. Time required varies with function and camera, but try one minute. Check display and setup menu for non-auto functions and date/time. Remove extra memory to eliminate this as a possible problem. Insert fully charged batteries and restart the camera.

It's probably the lens.

The gears become worn an a little sloppy, and also sopmetimes a little stiff.
This makes them overshoot the correct focus and then they have to try again resulting in the hnting you describe.

There can be other problems, but this is the most likley. Try another lens and see if you get the same problem.

Recheck everything about the camera.
Batteries, are they fresh, or fully recharged?
Too many problems without knowing more of what is happening, in my opinion.

Hi, there are many reasons why a camera may produce less then sharp pictures.

1) Dirty, oily or damaged lens: Check for dust and fingerprints.
Clean lenses with extreme caution, using dry lens paper.
Use only minimal pressure and gently wipe from the center
outwards, NEVER in circles.

If the lens is really dirty, ask a professional photo dealer to
clean it for you as a free courtesy.

2) Check to see if the auto-focus is working correctly, this could
be an electronic or mechanical problem requiring servicing.
Focus the camera on sharp image at various distances,
to see if it responds by moving the lens.

3) Can you focus the camera manually?

4) Can you focus by moving the camera back and forth
in regards to the object of interest?

5) Is the auto-focus feature somehow disabled in the menus ?

6) Are the batteries up to snuff, they may be strong enough to
turn on the camera, but too weak to move the focus motor.

7) Is the subject you are trying to focus on out of the
focus range of the lens: i.e. too close ?

8) Is the subject you are focusing on too bland, with insufficient
detail to activate and lock the auto-focus.

9) Do you have enough light for the auto-focus to operate.

10) Does the flash unit project an red pattern to help with
focusing.

11) Are you mistaking sharpness (focus) for depth of field.
In low light conditions, the lens iris opens wide, just
like your eye, to let more light in.

This results in a loss of focussed depth of field. This
means that focusing becomes much more sensitive
and critical, such that (when) the main subject is in focus,
everything behind and in front of the subject is not.

This is a theoretical limitation of all optical lenses:
The greater the focal length and the greater the aperture,
the shorter the depth of field.

This can actually be very beneficial when shooting a
portrait: Focus on the eyebrows, blur the background,

or it can be very detrimental: When trying to magnify
a butterfly on a tulip in low light conditions, getting
everything in focus is impossible.

12) Are you mistaking motion blur with lack of focus,
due to slow shutter speeds.

13) Are you shooting in very low light conditions,
causing the picture to become more noisy,
due to the way the digital camera sensor works.

14) I you come up empty on all these suggestions,
you probably have a defective camera and it is
warranty time:

a) Defective electronics
b) Defective auto-focus mechanism
c) Defective lens, loose internal elements
d) Detached sensor chip
.... etc

Try to isolate the problem. Try to manually and
automatically focus on a wide range of subjects,
at various distances, in bright daylight conditions.

If you are still unable to focus the camera,
it is probably defective and requires replacement
or servicing

BTW
Quick review of the internet, indicates that
this particular model is notorious for high battery drain
and battery connection problems. This may be the cause
of poor auto focus as indicated above.

Also this camera has insufficient internal memory, and
and an add-on memory card is required. It is possible
that without the memory card, the camera is defaulting
to a very low pixel resolution, in order to save memory
space, thus creating the appearance of poor focus.

The nominal resolution of the camera = 7.2 Mega Pixels
is respectable for such a low cost camera, but the
reliability reviews are not good.

i'd probably say try a repair place. It's a problem with retractable lenses.. better quality, but prone to problems.

Sounds like you need to get your camera fixed by Nikon.

However, you say the auto focus stopped working, you didn't switch to a lens that uses a mechanical focus linkage do you? The D40 only supports lenses with AF-S or AF-I type autofocus drives. AF-D and AF-G types without AF-S or AF-I don't autofocus.

Also, check that the A/M switch on the lens is in the correct position.

Manual focusing is quite difficult to do accurately with an AF camera. The screen inside the camera is not optimized for this. If you are sure you are focusing accurately but the pictures you take are still out of focus, the mirror may need adjusting. I can provide further info on this if you require, but if you're within warranty, i'd recommend that route first.

This is the camera trying to give itself enough light to focus with.

As it uses contrast to focus with you will get problems in low light conditions. There's no way round this I'm afraid except to light the subject better. As it's a digital camera and you're not wasting film, try manual focus and see what results you get.
