   I read the problem was discovered soon after release, one guy published tests and concluded that the problem was a myth, but he was using a 35mm lens, another found that a 1/2 kilo brass weight mounted using the tripod thread cured the problem. Either way the vibration is there and it's not surprising given the noise the shutter makes.  No doubt Sony are beavering away in the labs working on the new "A7 soft", it's a pity because the camera has so so much going for it, it certainly has created a new benchmark in modern photography.
