I like to run two camera bodies in a system. I do short trips specifically to take photos and I wouldn't want to have a body going down on me when I'd spent time and money going somewhere. At present I run an S5 and an S1R. I'm not sure the S1R will last the course - it's a fantastic camera in many ways, but its size & weight can be a challenge when travelling. So, I'm musing with letting it go and getting another S5 - but is it worth me going for the S5ii? It would be good to hear thoughts from those who have upgraded from one to the other, especially if you are principally a stills photographer. I know the S5ii offers a lot more for video shooters than the original model, but I don't do video at all so these would be wasted on me.
