Shooting in the dark here but what have you taken photo's of. is there a lot of glare that can effect focus. It is bright out is it hot also where you are, heat rising from the ground can effect a photo. Try a manual focus the lens may be having problems talking to the camera. Try some indoor shots. Just some suggestions

If your max shutter speed is 1/4000 and the camera would like to be even faster, say 1/8000 for the correct exposure, then 1/4000 shutter speed is too long. If the same thing happens at a slower shutter speed and a smaller aperture, then that's not the issue. I just saw that his lens was open on a very sunny day with ISO 200 and a 1/4000. That can cause issues similar to what he is seeing. I thought it was worth testing to avoid sending the camera for repair if that was the issue.
Or at least that's how it has worked for film. I could be way off base in the digital world.

| My ISO only goes to 200. That is the thing I miss with my 300d rebel (the 100 iso). I guess I will just play with settings and if it doesn't work, I will have to send it in. (unless anyone else has suggestions. I have been sitting here trying them all). Thanks! |

I have accidentally gotten results like this when my camera (Sony F707) was inadvertantly in the macro mode. Does your lens have a macro mode that it might be in by mistake? You might want to try some more controlled tests using a tripod and then trying different settings including various F-stop settings and shutter speeds. Make sure that you can actually see the image in focus through the viewfinder. If you are certain that the image is in focus while you are shooting then it is likely an internal problem. Please let us know what you find out.

Try using a tripod and use the timer mode on your camera. Use shutter priority and choose a shutter that will get you an aperture of somewhere around f/11.
Don't know if this helps, but if you can rule out things one at a time, you'll either find the problem or will realize it might need to be sent in for repairs.
Good luck. I hope you can figure it out. |

Go indoors. Get your tripod out. Get a ruler. Set the Camera at F/4 f/5.6 f/8. Manual focus on the number 3. Camera set to default sharpening. sRGB since you can't convert it in PS. Use mirror lock up, and timer to avoid any camera shake. Take a photo at each f/stop. Post the results.

What all this with the tripod and the mirror lock? At 1/4000 sec he should be able to jump up and down on the bed and still get a sharp image.
If you haven't already done so, try a different lens. If you get the same results at least you know you can rule the lens out.

Could you post an uncropped version of this photo?

That setting had been there and done that, he may not get 1/4000 if he shoots an image right now indoors. |

It's about isolating the problem. Using a tripod and mirror lock up rules out any issues of camera shake no matter how small they may be. The tripod also allows you to take the exact same shot over and over with different camera settings. You want to be able to test one thing at a time so you can systematically rule each thing out. What I see happen the most is people trying several different things at once because they are in a hurry and then if they resolve the issue they still don't have a clear idea which thing did the trick.

For an indoor test shot in manual focus mode on a fixed object to determine if there is a back focus issue. I'm not doubting that for this shot 1/4000 would eliminate camera shake, but for the indoor controlled environment shot, I would like to remove all variables.

I'm having the same concern regarding sharpness but nowhere near as bad as bradical.
In terms of sharpness I seem to see results that run hot and cold even with a tripod.
So one simple question
Does this photo look kinda sharp, given some major croping and file shrinkage? Or way off? |

Looks like a DOF issue. Overall from that sized shot, it looks fairly sharp.

Two touch. It was in AF.
I think I had some setting problems. I reset the camera and things seem to be working a little better. Thanks for all the help. I will post some updated test pics when I get a chance. |

Glad you figured it out. I know the feeling you get when your best camera stops working right.

I was just about to say maybe your diopter in your viewfinder was adjusted making whatever you thought was sharp, blurry.

Extremely good point... The only thing is, this wouldn't affect AF would it? I may need to adjust it just a tad for M though. I didn't think about that. |

It would in a way affect AF, He would keep af'ing until it looked sharp I assume and I dont really know what goes on inside Nikons as far as focus confirmation goes....

| Does your lens have a range switch? One that allows for faster focus so it doesn't havet to travel the full distance. If so, maybe you had it set to a range and the distance you were photographing was not in that range, therefore not in focus. Is that possible? |
