>>4243289APS-C is actually preferred for a core portion of my work because it turns my 600/4 into a 750/4 and I'm debating a D500 right now, honestly. I loved my D5600 when I had it, it weighed nothing and I would have probably re-done my Utah set I'll be posting soon with it just because of how light it was and how much better that would have been to carry over my F5 and gripped D800 on hiking trails in the 105*F heat. I will probably add a Zfc to my arsenal alongside my Zf when it gets here just on weight alone.
Would I redo my previous work in APS-C, probably not. A lot of it was a pain to do just to get on site and gain access. The only stuff I wouldn't redo in APS-C is probably my portrait work and even that could be re-done if I had to. Hell, if you count my D40, I still work in APS-C, pic related.
