I've just recenty noticed a rather strange phenomenon with my K-7: I usually travel with two tripods. A heavy wooden Berlebach and a simple metal tripod that has the great advantage of being set-up literally within seconds as you only need to push three locking tabs to make each of the legs unfold by spring force. Surprisingly solid and steady, that little thing. Put the K-7 with activated SR and Live View on the small tripod and within seconds the whole combination of camera and tripod will begin to strongly oscillate at around 10 Hertz. Obviously some resonance phenomenon triggered by the SR. Never seen anything like that before. Ralf -- Ralf R.
