It’s easy to reproduce the error, just have to use the camera for some time and it reveals itself automatically ! Canon 70D sucks ……
Sometimes it doesn’t recognize the battery, sometimes it doesn’t do anything at all and sometimes it only recommends to clean the lens contacts. I became the World Champion Lens Contact Cleaner ! But imagine when it happens right during the moment when the perfect photo-situation occurs ….
In short; ….. I totally lost my confidence in this high-tech Canon 70D camera. It was at techRepair for 2 weeks …. and when they tested it (5 minutes maybe?) it did all it was supposed to do. So they declared it “okay”.
Any good advice is welcome …..
