Nikon18-200mm lens what does the normal or active mean on the 18-200mm lens?

Ck your mirror lock setting. This setting is for cleaning, and what you described is just what happens on this setting. 

New nikon D 200 few months old.

Since yesterday, I need to press twice to shoot. With the first click the shutter opens ( I think) as there will be no vision through the eye finder. Then I need to click again. With the second click it shoots and everything gets back.

I did try changing the settings. with no diffrence. With shutter or apreture priority or manual and P it remains the same.

Any help will be appreciated.

Are you referring to a lens that has the Vibration Reduction? These are the settings:

• Normal - The image stabilization is on, but is for when you just hold the camera "still" by hand or are using a uni-pod.
• Active - The image stabilization is REALLY on, it's for when you have a shaky hand, like in a car or boat, or no uni-pod and you need extra sensitivity to control shake.
