Hi,
- Sony A7rII
- Canon 5DsR
- Nikon D 810
Sony A7rII helps you in getting proper focus and delivers great DR.
Canon 5DsR will yield best detail, but gives up on DR.
Nikon D810 lags the other two in resolution but offers great DR.
You may try the Fuji GFX and use a crop. May deliver the best image of all.
Another suggestion, buy a Sigma Art lens. it may be the best option…
Best regards
Erik
