A short while ago I bought a DSTE (sp?) grip for my 6D. Until today, I was happy with it. While on a shoot this afternoon, my 6D just shut off. It took me a few minutes to figure out the grip was flexing and that allowed the power contacts to unseat in the body. I just wiggled the grip and pushed it back in, and it worked fine... for a while. That happened about 3 times, today. I missed shots, which really P!$$#$ me off! My $2,300 6D/17-40 fell down on the job because of a $39 accessory. I do use a PeakDesigns Cuff, which is hooked to the grip, not the body. I use my 60D the same way and have never had this happen. Oh, the screw-mount things WAS still tight.
Does the Canon grip EVER do this? Has anyone ever had ANY grip do this? I've been using cheap grips for years. Opteka, Polaroid, and now DSTE. I've never had a problem like this before.
