Problem one Sometimes when taking a picture inside, I click the button half way it searches for focus and then takes the picture. Mind you I only clicked the button half way. Does this on the grip button and on camera one. Never had this occur in good lighting. It will do this on several picture attempts and then go back to normal. Only taking a picture when pressed all the way down. (does this quite often with low lighting) Problem two I had the 75-300 zoom attached the new version II I turned the camera on and the display had the overlay with info but no picture, it was blank. Turned the camera of and on about 4 times and it did the same thing. As I was about to give up, I turned the zoom lens to zoom in and the image appeared. (did this one time) Problem three Was outside taking a picture and the overlay was there but the screen was too dark to see the image, I had to jack the exposure comp to +3 to see the real time display. (did this once) Anyone else have similar problems?
