my experiences, I have an nx5 as my primary and a small sony HD handheld. I was looking for another smaller cam to shoot b cam with the nx5. I received it on a tuesday and had a wedding that saturday..I learned all the basic controls andoff we went...first hitch...no neutral density filter..ok, I'll set the shutter control up as a quick button as this was an outdoor wedding and the f stop only goes to 9 i believe?. The focus was set on auto and responded very nice and predictable. The active steady shot is very nice feature also.
