Read your manual and then read it again and.... make correct set upon your model camera,and....bee happy,your camera WILL shoot even out of focus,just make right set up.
Did i advise you to read manual??

Can you provide a page reference in the manual? I couldn't find it. The manual is downloadable from the Nikon site.

This does happen occasionally with certain settings. Usually under adverse(low light conditions) the camera cannot focus or cannot find exceptable exposure conditions with the settings you are trying to use. The sport mode will always take a picture whether or not the image is in focus. Read your manual thoroughly, learn the different focusing modes and how and when to use them correctly, learn what settings work under low light conditions. One of the most discussed issues on this forum are people having trouble focusing and getting sharp shots. It is the first thing people need to understand about their cameras. These new dslr's can do wonderful things but only if one knows how to use them. I read my manual when I first got my camera but didn't understand a lot. This forum has really helped me and then I reread my manual and things became so much clearer. The shots I take today are so much better then when I first got my camera.

Billy is right this can happen under low light situations and the camera doesn't quite know what to focus on....Try manual focus and that may rectify the problem

I don't have a Nikon, I have a Sony, and this happens to me occasionally also. Sometimes it is when there is no focus, and sometimes when I am closer to the subject than the minimum focal distance for the lens. Just a thought.

My D3100, on auto focus, randomly will not shoot. I assume it is because it is not focussing; if I switch to manual focus it shoots fine.
Same behavior with 2 different lenses. Sometimes if I zoom in and out, it will then focus and shoot fine. I can't find any other setting that correlates with the problem.
Does this sound like a camera malfunction?
Thanks for all ideas
Joe


Push the shutter buton down half way. let the camera focus, push it all the way down.

I've had similar situations with my D3100. Usually, it was because the ISO was too low for the aperture and shutter speed selected.

I can't remember if it ever happened on AUTO mode. But, if it did it was because the camera had not finished writing the file to the SD card.


Hey RV, you have to remember that if these new digital camera's don't like what your shooting, they won't shoot!!! So remember you have to please your camera first. I think I heard that from an old time film guy!

There may not be enough contrast at what your focus point is on to make the focus. Try moving the camera a hair or so to encompass two contrast points.

Had the same issue when I was new to the D3 - spend money to go to a Glamour workshop and couldn't get the damn thing to focus. The "smart guys" also in the workshop couldn't figure it out either. The next day I was in the store (still under warranty) explaining the problem and I was shown the answer. Moving the camera a hair works every time

Bingo. My D5200 was doing this to me at church this last as I was trying to capture some shots of the Easter play. I was trying to focus on the actors but they were moving around so then sometimes it was finding the wall, but there wasn't enough distinction on the wall to make it want to focus on it so I couldn't get a shot. So it happens to them all at times. If they can't focus it won't let you take a shot. On manual focus I never had a problem with it taking a picture. I did however have a hard time of trying to tell what the picture was of after because it hadn't focused.

I put this up once--and have no idea where it went--But--in addition to all the above this is exactly how a failing chip behaves--watch out because once it happens there is no hope.

I've heard that around military bases, digital cameras don't work because the government jams them. Yeah, let's start that rumor. :D

Could you have it set to "auto-focus lock"? (shutter only releases when AF locks focus)

My D3100 does this to me when I'm at an air show trying to follow something fast. If the plane gets out of the focus area, no pic. And the older I get the harder it is to follow the fast passes. Wish there were distance marks like on the OLD lenses.

Thanks to all who posted ideas and guidance on my focusing issue. I have tried several of the suggestions, but the issue persists. I am beginning to think I have a camera malfunction after all.
More details: I have the issue almost constantly, in high light and good contrast scenes. Recomposing does not help. Various shooting modes (P, S, A). I have the center cross focus point selected. When I press the shutter release, the tiny red light comes on very briefly, but the shutter does not release. Shutting down and restarting does not help either. Manual focus of course works fine.

Stan, what do you mean y a failing chip? The camera's CPU? The memory chip? Sounds like that could be a warranty issue for Nikkon??

Bring it to an actual camera store (not Best Buy) and ask someone to give it a try and see if he thinks it's actually broken. He might say there's a problem just so he can get the repair job, so begin by saying that it is under warranty.

Actual camera store, right, but easier said than done these days. Bought it a year+ ago at Ritz, who seem to be out of business. And it actually IS under Nikon's extended warranty, but the idea of mailing it off to them when I'm not even sure it's actually broken is not ideal!
