7D firing twice when shutter pressed half way, anyone else?
In the past 2 months I have had an issue with my 7D which is almost 2 years old and only shot 1948 times. The shutter when pressed half way to check the exposure details, fires 2 shots. This has happened only 3 times, the first 2 were in ISO 100 1/50 sec in Av mode and the third set at ISO 6400 trying to get a shot of the full moon last night.
The camera is set for RAW (of course) and ONE SHOT.
Maybe the new firmware upgrade in August will fix the problem but I was wondering if anyone else has had this experience.
Thanks for any input
