Question about Nikon D40x Digital Camera

1 Answer

Camera will not take pictures in Auto Focus Mode

My 18-200 VR lens will not allow pictures to be taken if it is in the A/M mode, but works as manual focus lens if it is in the "m" setting on the lens.  Other lenses work with body. The camera view finder says:  r 9 in lower right corner.  I think this ia an electronic problem with the particular lens. It is only 2 months old. NOt dropped or any damage.  How do I find error message codes?

My d80 wont take pictures in auto,P,S or A modes. Will click in M mode but no picture. What am I doing wrong? Treied to reset, but still does not work.

The camera will not take a picture in P, S, or A if the camera is in Auto Focus mode - and is unable to focus. Make sure that the Auto / Manual focus switch on the camera body AND the lens are BOTH in an Auto Focus mode. A tip off would be that you do not hear the lens focus motor running while trying to find focus.

If you do hear the focus motor, you may not have sufficient light on the subject for the camera to find a contrast "edge". In this case, the focus motor will hunt from where ever it is all the way in one direction, and then all the way in the other - trying to find focus. You'll need to provide more light or if you have the focus assist lamp (on the front of the camera) enabled - make sure your fingers are not blocking it while 1/2 pressing the shutter.

You can take pictures "all day long" in Manual Focus mode regardless of whether the subject is in focus or not. The lower left corner has a green circle or disc that indicates proper focus. Otherwise, a green triangle shape will be visible close by.

More info on Focus is available here. I hope this helps and good luck! Please rate my reply. Thanks.

It won't take pictures sometimes. push the shutter button and nothing happens.

The Nikon D40 in Auto Focus mode will only allow the shutter to operate when the image is in focus. When looking through the viewfinder, the bottom edge provides information relative to what you are looking at. See the image below:


Item 2 is the focus indicator. It must be illuminated to allow the shutter to release. If it is not illuminated, the lens has not been able to determine the correct focus. This can happen when attempting to take a picture in low light conditions. Make sure that the front facing "focus assist lamp" on the camera (between the shutter release and lens) has not been blocked or disabled (Settings Menu # 09) and try again. Many times, you will see and or hear the lens "hunt" for proper focus - the lens will travel from one end of its focus range to the other trying to find focus. When it can't, it stops and prevents the shutter from releasing. You can get around this "unable to focus" issue by changing the position of the switch on the lens to "Manual Focus" mode, detailed below:

If a lens has an "A - M" switch, move it to "M" to manually focus. If the switch says "M/A - M " then leave on M/A (unless you're going to be taking several or more in manual mode), as these lenses may be focused manually at any time in either position. As soon as you tap the shutter button in M/A you return to autofocus.

More advanced lenses, like the 18-200mm, 70-300mm VR and 18-135mm, and any lens with an M/A position, may be focused manually at any time without moving any switches. Leave them in their A or A/M positions.

I hope this helps and good luck!

All the pictures are blurry the auto focus isn't working

You may have put the camera on manual focus. Two ways to do that.
1. There is a switch on the lens which allows you to select auto or manual focus. Be sure the switch is set on A or A/M. If it's on M, you are on manual focus.

2. In you menus, there might be a mode which is manual focus. Look in your manual index under Focus, manual. There might be a setting in the Focus Mode menu.

You can also try resetting your camera. This will put most things back to factory default mode, including the focus mode.

When playing around with controls, go step by step through the manual and try things out. Be sure to set the control you were playing with back to default unless you really understand that setting.

After taken photos the image out of focus

On the front of the camera body, below the lens release button you should find a two position switch labeled "AF" & "M" This is the "Auto Focus - Manual" selector switch. Make sure the selector is set to "AF" for auto focusing.

Your lens may have a similar focus selector switch on its barrel. There are two types of switches used - depending on the lens. The first is labeled "M/A" and "M" The "M/A" position indicates it is in "Auto Focus" mode with a "Manual" focus over ride capability. You can simply twist the focus ring to change the focus to a point other than that chosen by the camera's auto focus system. The "M" position is Manual Focus mode. No focusing operations will be performed by the D80 auto focus system - focusing must be done by the photographer.

The second type has "A" & "M" positions. These represent Auto and Manual focus. The difference between this type switch and the "A/M & "M" switch is that when in "A", the camera will no allow the focus to be changed manually. There will be opposition to twisting the focus ring in the position. Forcing it will likely result in damage. The selector switch must be changed to "M" to change the focus.

If either switch is set to manual, the auto focus system will be disabled, so it is very important to have them both set to "A" or "A/M".

I hope this helps. Please rate my reply - thanks!

Lens unable to auto focus

try cleaning the lens.

Also set the focus range in the camera to average both vertically and horizontally. That is when you press the shutter button thos red squares in the look through a;; ;light up rather than just the centre square.

I suspect it is getting feedback from something on the lens that it reads and tries to focus on that is closer than the object you want to photograph. Make sure there is no mold growth inside lens as that will do it too

Autofcous and manual focus do not work

excuse me if this is a dumb question but you wouldn't believe the things people do...., but in manual mode are you actually manually trying to move the lens? as manual mode means just that you take hold of the lens and turn it. If it wont turn it sounds like the lens is jammed and needs returning/repairing.

if taking hold of the lens and turning it works for manual mode, take the lens off and clean the gold contacts on both the camera and the lens with a pencil erasor this may bring the auto focus back to life, switch back to auto and try again, if not its most likely the lens but take the body to a canon store and try another lens just to double check the body is ok

drop me a line if i can be of further assistance

best of luck

Nikon d40 digital camera

When the camera is in auto focus mode, it will not take the picture until it locks onto a subject. If there is not enough light, the camera will "hunt" for something to focus on. Since it can't define any edges, it won't allow the shutter to release.

The D40 base model does NOT have a powered focus lever for autofocus, so if the autofocus is not working, suspect the lens.

Very long shutter release delay

This is weird, usually shutter delays are caused because camera is trying to focus first, it really shouldn't happen after pre-focus. do you have a manual focus mode? if you do, try it and see if it works. if you dont, I would still suspect it some kind of focusing problem, but unfortunalty i have no idea how you can fix it yourself.
