Anyone here sold his d750 after getting the a7ii/a7r2. Got the a7ii now to test and going back and forth deciding if I should sell it or not.
The a7II should be a good indication on whether or not replacing your DSLR with the a7rII is a good move for you or not. In terms of camera operation, the a7II is actually very similar to the a7rII. Most of the a7rII advantages revolve around the sensor.
I could have honestly replaced my 5DIII with the a7II…the only downside was the inability to use my 24-70II and 70-200II on an a7 body, or having equivalent f2.8 zooms for the native FE mount. The ability to use on sensor phase detect with adapted lenses is the feature that tipped me over the edge in terms of selling my 5DIII.
I don’t shoot sports or wild life, but the a7II and a7rII are perfectly adequate for shootings kids, events, etc. Mind you the 5DIII has a very sophisticated AF system migrated from Canon’s flagship sports cameras…I’ve always felt they were overkill for my uses. I never fully figured out how to fine-tune the AF tracking system, and it was highly underutilized by me. I keep it in one of the pre-set sport modes (skating).
