I do not want to stir a hornets nest here at all.
I was looking for the cheapest (new) mirrorless cam on ebay and noticed that the Samsung NX mini at 79 Euros is the one. There are also new NX3000 units for 20 euros more. Barring the Sony A3000, not even the oldest NEX (used) go for this low.
Also (coincidence or not) there aren't many adapters to use legacy lenses on the NX or the mini though Samsung has a fairly decent lens line up.
This may seem like a conjecture but there may be a connection and some truth to the adaptability of the E mount.
Some food for thought as new, pricey lenses are being announced for the E mount nowadays.
