Samsung NX300 review by Kirk Tuck is up: The Visual Science Lab / Kirk Tuck: The Samsung NX300. A review. I must add, I have used a pre-production model of the NX300 and it is easily one of the best compact mirrorless cameras on the market. Samsung took great pains to ensure that all the problems they had with previous NX cameras are rectified. I eagerly await the arrival of the NX30... Although my sources at Samsung indicate that it actually may never arrive. Which is a pity.
