There is nothing Canon has that could tempt me to go mirrorless. What does Canon have to replace my 5DSR? What about very low light autofocus and battery life or sensor resolution? I do not want a smaller body. If I was starting from scratch I might be tempted by Panasonic's new FF entry, might being the operative word. If my 5DSR was stolen today I would replace it tomorrow with another 5DSR. Does that answer your question??
