Thanks again for all the great, in-depth recommendations in this thread.
Like @IronFilm suggested, MFT seems to be more sensible choice given I already have some MFT glass and, working solo, I need to travel as light as possible.
I've been looking for used GH5s, but am wondering now what would be the pros and cons of going for the BM P4K instead? And as my main camera (used for tight shots), is the GH7 still the best choice these days?
