Hey My Canon D7 Works fine when I use LCD as viewfinder. Buf if I use the normal viewfinder, all other modes than M won't work right. Example: If i use AV mode the shutter speed would stay (blinking) on 8000 unless what aberture I choose. Only if I change the aberture til 16 or above the shutter speed will fall to about (6000). Its the same problem when i use the TV mode. Then it's just the aberture that stays hisgh unless the speed is changed. The result is Black Photos. It seems that the aberture and speed are interchangeable, but not callibrated. Changing ISO or light compensation doesnt solve the problem. Do anyone have any ideas what is going on? /Kristian
To trouble shoot your problem, I would look at doing the following. I would do a factory reset of the camera. Make sure that you are using the latest firmware for the camera. I would clean the contacts on the camera, as well the lens. I would also look at trying another lens to see if you get the same results. Try a different memory card as well. Gary
