Nikon D5100 slow shutter?

I just purchased the new D5100. When I use the view finder, it takes the picture fine, but when alI switch to the lcd screen in seems to lag when I hit the shutter and take a picture. Why? And how do I fix it?

You fix it by not use the LCD.

The viewfinder is literally a window… Its reflected light off a mirror inside the camera body.

The LCD screen on the other hand flips the mirror out of the way and then reads the data being captured by the sensor this is inherrently slower than the speed of light.

There's a ton of reasons why oyu shouldn't use the back screen for composing shots (how oyu hold the camera, slowness of taking the picture, auto focus issues… ).

There are only a few times when shooting with the LCD is useful. I can count on the fingers of one hand the number of times when I;ve had to use the LCD to shoot.

You shouldn't be using the LCD to take pictures, except under exceptional circumstances. 'real' photographers use the viewfinder to frame & compose their shots.

Eric, truly nailed it, and deserves the points. The LCD screen should be used for just a few things, the first and foremost is the histogram. That will tell you more about your photograph than anything else. The next is composition, but that is not really a good point as you should know what you're taking a picture of. Anything else is probably a bad idea. Let me give you an example. When you're looking at the back of the screen after you take a shot, you're not shooting. If you were hired to shoot an event like sports, if you're looking at the screen, you're not taking pictures. Photographers have been fired from their jobs for looking at the screen instead of shooting. What happens if something amazing happens and your off in lala land? You didn't get the shot. Fired!

One thing that may help you to break the habit is to set up your camera, and then put black tape over the little screen so you can't see it. You'll find that the photo's improve.

Those little cameras that force you to look at the screen as you shoot are a terrible thing, don't think that good photographs work that way.
