Well, here's my last 3 with Fuji. No one has complained about me missing key moments. In fact they've been saying the opposite. It all depends on style of shooting I suppose - I never was into rapid fire shooting even when I shot mostly w DSLRs. I can't fathom shooting in the way that some photographers do - shooting 7-10,000 images at a wedding. It's just not my style. Mine is much more of an "be there, be ready, anticipate, then click" approach. But I don't disregard that it works for some - to each his own. There are many different tools capable of producing fine images on a wedding day, just like there's many different photographers.

Of course full disclosure I also use a Ricoh GR a lot when it comes to the "party dancing" because I like the look. And occasionally a Nikon D750 although not much these days - maybe a few shots here and there on those weddings from my second shooter.
