Was stated in another thread that the NX20 did not have it, I would imagine that means the 10 didn't either.
Well the new NX30 will surely have it.
So, were you looking at replacing your Micro 4/3 kit, or doubling up with two systems? I've been trying to keep them from overlapping by keeping the NX300 with the two 20mm and 30mm pancake primes, and keeping my Micro 4/3 kit with a few zooms and my favourite primes.
There's a few Samsung lenses that I am interested in (12-24mm, 45mm, and the new 16-50mm) but they would open up larger questions of how I want to balance the two systems.
