Nikon D780 vs Nikon Z 5

The Nikon D780 is better overall than the Nikon Z 5, though they use different camera technologies. Though both are full-frame cameras, the D780 is an enthusiast-level DSLR, so it has an optical viewfinder, while the Z 5 is an entry-level mirrorless camera with an electronic viewfinder. Both feel well-built and comfortable to shoot with, but the Z 5 is significantly lighter and more portable. The D780 has a longer battery life and a more versatile autofocus system since it uses both contrast- and phase-detection AF depending on whether you shoot through the viewfinder or Live View on the screen. The Z 5 can only shoot 4k video with a severe crop, but on the upside, it has in-body image stabilization, meaning you can use non-optically stabilized lenses.
