So what do you guys think of this? Something worth considering if using M lenses but can't afford an actual Leica body? Or pointless when you can just use an adapter on a mirror-less body?

For me, its a question of whether or not that viewfinder is an actual rangefinder, or just a rangefinder-esque viewfinder like the Fuji Xpro.
