That is a perfect example where live view is essential where you can check the focus *before* taking a shot and making the process fast.I have the ZM Sonnar 50/1.5, and the focus shift is easily detectable and can be compensated for with a little practice. when stopping down, leave the RF image slightly offset- stop a little bit on the close side. Stopping down shifts the focus towards infinity, past what the RF indicates.
FWIW, that particular example of a lens is not the fault of the RF but the lens' design and Zeiss' decision to make and sell it to the RF users!
