Okay, I constantly see many people obsessing over what equipment they have. Let's forget that we've (mostly) all spent too much money on camera equipment, if your XXX equipment disappeared tomorrow, and XXX was gone and no XXX equipment existed used (think movie Yesterday), and you needed to buy new camera equipment - from scratch - What would you buy? You have no lenses, no adaptors, nothing remains from your XXX memory whatsoever.
Thankfully, this is simply an exercise to move you out of your box (Leica box in my case). Really, an exercise in thinking about photographic creativity rather than equipment make or model.
For me, it's a no-brainer. I considered Sony the best in the industry, so I would continue with my Sony gear in the absence of Leica.
