My Nikon D7000 has randomly started making me have to press the shutter button again after i've already taken a photo?
I think i might have pressed a button or something but every time i take a photo the shutter sound doesn't fully finish, and the screen goes black, so i have to press the shutter button and the shutter sound finishes and the screen isn't black anymore, this hasn't happened to me before and i really need to get it sorted!

Does the Nikon D5100 take picture slower in live view v.using the viewfinder?
I just got my camera so I'm still in the process of learning the ins & outs.
I was able to figure out how to use the live view way but when I went to take a picture, after focusing, it was considerably slower in taking a photo (& noisier.)
Is that supposed to happen? Just want to make sure it's not something wrong with my camera.
