A7RII: photography pipe dream or technical marvel? I keep looking at other Mirrorlessons cameras like this and keep thinking about if these cameras are competitors to M43. On one hand, it would be great to have a larger sensor with high pixel count. On the other hand, the large lenses basically means I would be carrying a lot more weight again. What are your thoughts on such a camera compared to M43 cameras? If you were to choose between systems, would you prefer the A7RII to M43?
