Quick answer
Choose the Nikon D780 if you prefer a traditional DSLR with an optical viewfinder, longer battery life, and access to a vast F-mount lens library. The Z6 II is the better choice if you want a smaller, lighter mirrorless body with superior video features and native Z-mount lens performance.
Optical Viewfinder vs Electronic Viewfinder
The D780's optical viewfinder gives you a direct, lag-free view of your subject, which many photographers prefer for fast action or when shooting in bright sunlight. The Z6 II's electronic viewfinder shows you the final exposure, white balance, and depth of field in real time, making it easier to nail the shot without chimping. This is a fundamental choice between a classic shooting experience and modern convenience.
Lens System and Compatibility
The D780 uses Nikon's F-mount, which has decades of lenses available at various price points, from vintage glass to modern AF-S and AF-P lenses. The Z6 II uses the newer Z-mount, which requires an adapter (FTZ) to use F-mount lenses. While the Z-mount lenses are optically superior, the adapter adds cost and a bit of bulk. If you already own a collection of F-mount lenses, the D780 is the more practical choice.
Key trade-offs at a glance
- Viewfinder: D780: Optical (OVF) – no lag, works with camera off. Z6 II: Electronic (EVF) – shows exposure preview, but can drain battery faster. If you shoot fast sports or birds in flight, the OVF may give you a more responsive feel.
- Battery life: D780: ~2260 shots per charge (CIPA). Z6 II: ~410 shots per charge (CIPA). The DSLR's optical finder and mechanical shutter save significant power. For all-day shoots without charging, the D780 is the clear winner.
- Weight and size: D780: 840g with battery and card. Z6 II: 705g with battery and card. The mirrorless body is noticeably lighter for travel or handheld work. If you hike or walk long distances, the Z6 II reduces fatigue.
- Video capabilities: D780: 4K UHD at 30p (full-frame or DX crop). Z6 II: 4K UHD at 60p (full-frame), 10-bit N-Log output via HDMI. The Z6 II offers higher frame rates and better color grading options. For serious videography, the Z6 II is the better tool.
- Lens ecosystem: D780: Native F-mount with hundreds of lenses from Nikon and third parties. Z6 II: Native Z-mount with growing lineup; requires FTZ adapter for F-mount lenses. If you have a large F-mount collection, the D780 avoids adapter costs and compatibility quirks.
