Re: Panasonic gx80 for weddings
 

My last wedding it was 34 deg and there was a glaring sun, I think that in terms of having to deal with harsh light there was not much difference compared to Spain :)
Te only thing I would worry about with fixed lens camera such as the rx10 and the xc10 is low light sensitivity, especially when you zoom in with the xc10 the lens ramps up to f5.6 which will make it useless in dark venues, there a gx80 will have the advantage of fast primes. Also when you want to shoot in 4K the 305mb bitrate on the xc10 sounds like overkill, the cost for the media will be a lot higher in such a case.
One camera that might be interesting is the upcoming g8 and eventhough it's only rumors so far it's expected to have the same ibis as the gx80 but with a lcd screen that can be opened and hopefully a audio input. Sort of a poor mans gh5 :) If it follows the same pricing as the g7 it's going to be very cheap. We should know more this month.
