Can anyone tell me why when I take a pic of a car (like in attached photo) the rear of the car goes out of focus? And what I need to do to fix this problem?

This has happened with every D-Camera I have owned, and I have tryed a # of different things, but obviously not the right thing! I'm a novice, but have tryed diff. ap. and shutter speed setting with no luck...even have tryed with all the camera's built in settings.....same thing everytime....driving me nuts.

HELP ME PLEASE!

Thanks! Sean-

Try a google on something like "understanding depth of field". Found this :

http://www.apogeephoto.com/feb2005/j...en2_2005.shtml

Essentially you should :

1. Use a smaller aperture than the f2.8 you used (down to f8 is available on your camera);

2. Perhaps not focus on the very front of the car but a bit beyond that so that you don't "waste" DOF in front of the point you've focussed on.

If you had used f8 for this shot and no further light was available, you would require a shutter speed of 1/8 sec. You'd probably need a camera support of some kind to avoid camera shake and hence having the whole car blurred :-)

Looks like a model car so why not use flash, f8. You also shot in landscape mode. Shoot aperture priority f8 with flash.

As everyone has said...use a smaller aperature...meaning use F8 and focus on the centre of the car...by which I mean the end of the front door. I am sure you should get the whole car is sharp focus...
I have a FZ15 and I can vouch that with correct settings You can get the most of you frame in sharp focus...

Just to prove the point...the tree on the left is in focus as well the one next to it. Both are more than 60- 70 feet away...Although there is fractional blurr...still can be called sharp enough..


Here is the summary of exif...
Make = Panasonic
Model = DMC-FZ15
Exposure Time = 1/160"
F Number = F8
Exposure Program = Manual
ISO Speed Ratings = 64
Exposure Bias Value = ±0EV
Max Aperture Value = F2.83
Focal Length = 47.1mm
Exposure Mode = Manual exposure
White Balance = Auto white balance
Focal Length In 35mm Film = 275mm
Scene Capture Type = Normal

Thanks a ton guys! I will read that DOF article and try the F8 with flash - although I do not want any real shinny spots on the car like what might happen with the flash.

Also - how you guys know all that info on my picture? Like the settings I used and mode...?
