I currently have a Nikon 1 V1 with 2 lenses and the SB-N5 speedlight but it is quite bulky so we want to get something more compact but with similar features. The current sale of the J4 and A5000 has got me looking at those two. Of course the pro's of the A5000 is the large APS-C sensor but everything else seems to favor the Nikon J4. They both have built-in flashes which is mainly what we looking for and the Nikon is stupid fast with the 18.5 f/1.8 which the Sony just can't touch. Also looked at the Sony RX100 II but the speed is not there. Anything else I should be looking at?
