The noted vibration for the A7r cameras are related to tripod mounted images particularly with lenses longer than 100mm in the 1/125 to about 1/15 second range. Certain lens appear to be more prone to the issue. I have noted it while using my tripod mounted A7r with my Leica R 180mm f3.4 Apo Telyt (with the Novoflex rotating collar and Novoflex adapter) as well as with my Leica R 280mm f4 Apo Telyt lens. I am not sure if I have noted the issue with my Leica R 80-200mm f4 Vario Elmar lens since I do not use it often. I have not noted it with my Leica R 100mm f2.8 Apo-Macro_Elmarit lens with the same Novoflex Adapter and the Novoflex Rotating collar. My tripod head for these image consisted of my Markins M20 head with Krk 2 1/2\" QR clamp and the tripod is the RRS TVC-24L tripod along with the RRS TA-2-LC leveling base with clamp. The plate on my Leica R 280mm f4 Apo Telyt lens is the RRS 97L plate. I have come up with some methods that probably yield images with no problem in the mentioned shutter speeds with the lenses mentioned as well as when using the Leica R 280mm f4 Apo Telyt lens along with either the Leica R 1.4X or the Leica R 2X Apo Extenders. I probably have been able to get a 75% success rate now in those shutter ranges.
