Thanks Bill, I'll have a read of the content when I have a spare half hour... in the summary - here's the most important comment for me :
"Anybody hoping to capitalize on the NX10's mirrorless layout (and consequent short sensor-to-mount distance), to use non NX-mount lenses via adapters will also be disappointed because you can't manually engage magnified live view so can't realistically manually focus lenses. "
One of the saving features of m4/3rds (given the still thin selection of native m4/3rds lenses) was the ability to use pretty much any lens with an adapter.
Cheers
Brian
