Since a while I have a sony a7r2 with in camera image stabilization. I intend to make use of this in combination with a legacy macro lens with fixed focus (in my case a macro elmarit r, f=60mm or a micro nikkor 4/200). I do not precisely know how the image stabilization operates but I guess, camera + lens is considered to be a solid system which, hand held, suffers from some "zitterbewegung" inducing a vibration of the picture at the position of the sensor and this vibration has to be compensated. The relevant parameter the system has to know , in my view, is the distance between sensor and lens, that is focal length f + move of the lens, e.g. in case of a 1:1 macro picture together 2f, in case of a 1:2 mapping it would be (1+1/2)f. Therefore I should insert this value instead of f (as is requested in the manual of the camera). - Does someone have experience ?
