Nikon Z 6II vs D780: Choose the Camera That Fits Your Workflow

Choose Z 6II if you want an electronic finder that previews selected picture settings and a native Z-mount path; choose D780 if you prefer an optical pentaprism finder, direct compatibility with supported F-mount lenses and two SD slots. The lens and card transition matters as much as finder preference.

The buying question

Should you choose Z 6II's mirrorless EVF and Z/FTZ lens path or D780's optical finder and F-mount workflow?

Z 6II combines electronic finder preview and native Z mount with a CFexpress/XQD-plus-SD card arrangement; D780 pairs an optical pentaprism finder and F mount with two SD slots.

Quick verdict

Choose Nikon Z 6II (U.S. body, model 1659) if

  • You want an EVF that shows selected exposure and picture settings in real time.
  • You are building around Z-mount lenses, or will check compatibility before using F-mount lenses with the optional FTZ adapter.

Choose Nikon D780 (U.S. body, model 1618) if

  • You prefer an eye-level optical pentaprism finder.
  • Your compatible lens kit and memory-card workflow are centered on Nikon F mount and SD cards.

When to skip: Neither finder experience fits how you compose.
When the recommendation changes
  • An exact existing lens or card is central to the setup; confirm its model-specific compatibility and slot use before choosing. If you plan to use the original FTZ on Z 6II, it must have firmware v1.10 or later.
  • Finder preference is the deciding factor; specifications cannot determine which view you will personally prefer.
  • The live seller, price or included items differ at checkout; compare the current total and confirm which accessories are included before buying.

The differences that matter

Viewfinder Workflow

Nikon Z 6II (U.S. body, model 1659)

The Z 6II has an OLED electronic viewfinder that can show exposure, ISO, white balance, Picture Control and creative filters in real time; the displayed information can be customized.[1, 3]

Nikon D780 (U.S. body, model 1618)

The D780 has an eye-level pentaprism SLR optical finder with approximately 100% horizontal and vertical FX-frame coverage.[2, 4]

What this changes: Choose by finder preference: the Z 6II can preview selected settings electronically, while the D780 preserves a through-the-lens optical finder. The D780 also supports monitor Live View, so the distinction here is the eye-level finder workflow.[1, 2, 4]

The better fit depends on your priorities

Lens Media Workflow

Nikon Z 6II (U.S. body, model 1659)

The Z 6II uses Z-mount lenses natively; Nikon says F-mount NIKKOR lenses need an adapter and restrictions may apply. Its slots accept CFexpress Type B/XQD and SD/UHS-II cards, with backup and file-separation options. For the original FTZ adapter, Nikon requires firmware v1.10 or later; v1.00 is not supported.[1, 3]

Nikon D780 (U.S. body, model 1618)

The D780 uses Nikon F mount with model-specific compatibility restrictions; it has two SD/UHS-II-capable slots that can be used for overflow, backup or separate RAW/JPEG storage.[2, 4, 5]

What this changes: A compatible F-mount kit mounts directly on the D780. Moving those lenses to Z 6II requires the optional FTZ adapter, and each exact lens should be checked. The D780 keeps a dual-SD workflow; the Z 6II mixes CFexpress Type B/XQD with SD, so card inventory can affect the system transition. If using the original FTZ, check that its firmware is v1.10 or later before relying on that lens path.[1, 2, 3, 4, 5]

The better fit depends on your priorities

Electronic-finder preview versus optical through-the-lens finder

The better fit depends on your priorities

The choice depends on whether electronic settings preview or an optical pentaprism view fits the photographer's preference.

Keeping an existing Nikon lens and card workflow

The better fit depends on your priorities

The exact F lenses and cards already owned determine whether direct F mount and dual SD or an FTZ adapter and mixed CFexpress/XQD-plus-SD setup fit better.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Judge any current price gap against finder preference, lens transition and card workflow; the published specifications do not establish a universal value winner.

Compare current checkout prices, sellers, body-only status and availability when ready to buy; available evidence does not support a price-history timing recommendation.

Limitations

  • This comparison uses manufacturer information; no hands-on tests were performed and no image-quality, autofocus, video-quality or reliability ranking is made.
  • Check Nikon's compatibility guidance for your exact F-mount lens. FTZ is optional for F lenses on Z 6II and restrictions may vary by lens. Nikon specifically states that the original FTZ needs firmware v1.10 or later for Z 6II; v1.00 is not supported.
  • Before checkout, verify the seller's included items; bundle contents can vary.
  • Finder and card specifications explain workflow, not which camera will make better photographs for an individual.

Questions shoppers ask

Will an F-mount lens work on the Z 6II?

Nikon says F-mount NIKKOR lenses require a mount adapter on the Z 6II and restrictions may apply. Check the exact lens and adapter combination. The D780 uses an F mount, but its own compatibility guide lists exceptions and restrictions. For the original FTZ adapter, Nikon requires firmware v1.10 or later on Z 6II and does not support v1.00.

Can I continue using SD cards on either body?

Both bodies accept SD cards. The D780 has two SD slots; the Z 6II pairs its SD slot with a CFexpress Type B/XQD slot. Nikon lists backup and file-separation options for both cameras.
