Nikon Z8 wins for hybrid shooters with 8K30 video and 20 fps bursts (per RTINGS and CNET) while Sony A7R V delivers 61 MP detail for landscapes (per DPReview) but caps at 4K60. The Z8's heavier build trades off against the A7R V's lighter 723 g frame. This is a close call for stills-only users but Z8 pulls ahead overall.
