D3000 nikon focus issues?

When I focus in on my target with my Nikon d3000. I use a 55-200 oe 18-55 lens, the target has great focus but its blurred all around. I was trying to take pics of staggered people but could only focus on one at a time.plus what mode is best when shooting with good light. I usually just use sports mode.

Added (1). Sorry will not go to webs I do not know.

Added (2). Yes sorry the camera was a gift in a way and I can't afford a Class. All I know is when i do the recommended settings for aperture and shutter the pics end up black even in broad day light, rudeness is not needed, this web is here for these types of questions. Just didn't know why the Focal blur and when i do the manual settings it fixes the blur but then the pictures are crazy dark.sorry

It seems that you are shooting with the aperture of the lens wide open. Stop down at least three stops to increase your depth of field. You do know, don't you, that not only the aperture you use controls depth of field but the longer the lens, the less apparent depth of field you will get at similar apertures. This is true of ANY dSLR, not just D3000's

Taking a basic class in photography will solve this and may other fundamental problems as a new shooter

The "issue" you're having is caused by shallow depth of field. Depth of field is largely controlled by aperture and focal distance. To have more of your shot in focus, you need a smaller aperture and a closer focusing distance. Set your camera to aperture priority mode and manually set the aperture to a higher number. Zoom with your feet instead of with your lens; get closer to the subjects.

I understand the desire to not visit unfamiliar websites, but please consider taking a look at this explanation of depth of field from Cambridge in Colour. They have some excellent diagrams and examples to illustrate the concept. Http://www.cambridgeincolour.com/tutorials/depth-of-field.htm

Your problem is simple… You have absolutely no understanding of basic photography or how your camera works. If you plan on using auto modes, sell your DSLR and buy a point and shoot… Your trying to use your DSLR like a point and shoot anyway, you might as well save a few hundred dollars. Of course you won't look like a pro, which is really why you bought the DSLR in the first place.
