RX1 or RX100 Backpacking the World.

RX1 - ultimate image quality but you are limited to one focal length.  That sounds romantic but it is, well, limiting.

Needs to be carried in a visible case even in areas where you would rather people not know you have a camera.

Kind of expensive to leave in a hostel.

RX100 - great image quality FOR ITS SIZE.  Some focal length flexibility.  Super discrete; can literally be carried in a pocket.  Less of a hit if loss/stolen.

Love my RX100 but I also love the images from FF cameras ( I also have a 5D3).

A very tough choice.  My practical side would dictate the RX100 but my desperation for ultimate image quality would suggest the RX1.

I would probably go with the RX1 myself; despite its limitations.  I can't see not bringing  the EVF though.

I think.
