A quick shootout between three affordable and relatively small 4K cameras. I didn’t do any grading, just correcting to “normal” colors.
You can get them here,
The two Samsungs are sharper, has better colors and of course shallower depth of field. They are also cheaper.
The Sony handles highlights better and is very small and light.
For serious videos the NX1 is the only viable option since the others are to limited. But as a compact traveler I would say the NX500 if money is an issue and the RX100iv if the price doesn’t bother you.
Difference in sharpness is quite obvious.
