Sounds like you might be in Live View or mirror lock.

Hi jrhoffman75, Thank you so much for your response, how I unlock or change that live view mode this happend when I use the viewfinder i always shoot using that way no the screen, thanks again for your help

If this happens when you are loking through viefinder, not the LCD on rear of camera, then Live View is not the cause of your problem.

Follow these two steps:

Sounds like it's in mirror lock up.
