First, digital cameras like the RX100 II and a5000 shoot video, not film.
RX100 II
Pros: Small, compact, has a hot shoe. Allows use of external flash and use of the Sony ECM-XYSTM1 external stereo microphone. Wi-Fi connectivity.
Cons: Small sensor (13.2mm x 8.8mm) about 3 times smaller than the a5000 sensor. Permanently attached variable aperture f/1.8-4.9 zoom lens.
A5000
Pros: Large APS-C sized sensor (23.2mm x 15.4mm) which performs better at high ISO settings in low light. Interchangeable lenses for maximum versatility. The Sony LA-EA3 or LA-EA4 adapters allow use of all Minolta Maxxum/Sony "A" mount lenses. Wi-Fi connectivity.
Cons: No hot shoe so no external flash compatibility nor use of the ECM-XYSTM1 external stereo microphone.
Sony a6000:
Pros: Interchangeable lenses, use of LA-EA3 or LA-EA4 adapters just like the a5000. Hot shoe allows use of external flash and the ECM-XYSTM1 external stereo microphone. Slightly larger sensor than the a5000. Wi-Fi connectivity.
Cons: Lacks the variable angle rear screen of the a5000.
So in my opinion the choice should be between the a5000 and the a6000 with the a6000 winning because of its hot shoe.
