This review is not a spec review but a personal review of the Sony camera system. At the time of this writing, the Sony A7R IV has already been out for 10 months and I have already parted ways with my A7R III six months ago. It wasn’t for a direct upgrade because I feel like the A7R III was already good or better than good enough for most things. On the contrary, I opted for a completely manual system with less features on a spec sheet. Part of the reason for this was due to how my shooting style evolved. I’ll explain.
