17/1/09 was a sad day as my D80 failed on me when i need it the most.I was shooting an engagement yesterday afternoon,i was setting my camera to shoot when i found out i cant changed the aperature setting as it stuck at F2.8 for a few frame even i change to my 50mm.It took awhile to fix the bug when i decided to switch it off and on and prayed hard.It worked perfectly until the next two hours and it started to creat another as it begin to underexposure the shots for no reason even i didn't change the setting on flash nor the camera.I powered down the camera n prayed hard for the next hour to worked perfectly.After that it went smoothly with no problems.It was nerve racking moment yesterday as i never had face a problem like this before. Maybe its time for new camera.
