My 7D is D.O.A.
My Canon 7D died this weekend. It started acting up on Friday at FeatherFest at San Luis Pass. Shutter would lock up with error 20. Took the battery out and got it to work after trying it several times. Went back out yesterday to Brazos Bend and it started doing it again. Took it back to the car and got my 40D. I forgot how much difference there is between the 7D and the 40D. The autofocus on the 7D blows the 40D out of the water. There is no comparison. Got frustrated and left early. Packed the 7D up and sent it back to Canon for repairs.
I’m guessing that the shutter will have to be replaced, which is a surprise since I’ve only had it since last June. I’m guessing that I’ve got around 100,000 actuations with 85 shooting trips in the last 10 months. The 7D’s shutter is supposed to be rated for 150,000 actuations. I’ve been through 4 shutters on my other cameras so this may be the 5th. I’ll just have to wait and see what Canon says.
