I've been thinking about entering the mirrorless world. A toss up between the Sony A7iii, the Nikon Z6 and the Canon EOS-R. It's a hard decision, particularly when coming from a camera I love so much the D750. So far the Sony A7iii's ergonomics and menu system have put me off, and I'm not so keen on how the photos look, and the EOS-R hasn't got as strong an overall score in terms of DXO sensor rating as the D750 with not as good low light performance. Finally the Z6 hasn't got the benifits of Eye AF without switching modes, it would have been nice to switch between using single spot AF and face/eye detect with the press of a button or have both on the same mode. Also single card slot would worry me for Weddings. Perhaps now isn't the time to switch entirely to mirrorless. Also contimplated having a go with the Fujifilm X-H1 with its solid build and fancy shutter mech. Although I do like the qualities of a full frame camera coming from the D500. Dilemmas!! Perhaps just another D500, D750 or a D810, but it would be nice to have some of the latest mirrorless features
