NIKON Z5 Low Light Autofocus -v- Nikon D780 Real World Comparison

Summary of Technological Concepts / Product Comparison (Nikon Z5 vs Nikon D780)

Goal of the Video

The video evaluates the real-world low-light autofocus performance of the Nikon Z5, with a direct comparison to the Nikon D780, using the same lens and similar settings.

The reviewer reports using the Z5 for about 35 weddings over ~9–10 months—initially as a backup camera, but now often choosing it over the D780. Their core claim is that low-light autofocus is “very close,” with the D780 only slightly ahead.

Key Setup / Test Method (Real-World Approach)

• Same lens on both cameras, with the reviewer emphasizing identical conditions.
• Video demonstration style: The speaker records from the camera viewpoint (not through the camera) and describes how dark the room is so viewers can compare:
  • Time-to-focus / acquisition speed in dim conditions
  • How quickly each camera locks focus after pointing at different subjects
• Test scene / lighting: A dark lounge environment with curtains drawn (January morning dimness). The reviewer uses varied and challenging elements such as:
  • Curtains, carpet, furniture
  • Darker targets (e.g., a black statue) to stress autofocus

Autofocus Behavior and Settings Mentioned

D780 Test

• Uses single-shot autofocus (even though the reviewer says they normally use continuous AF with back-button focus).
• Focus behavior is tested by:
  • Pointing at darker targets
  • Moving the camera away and then triggering acquisition by pressing focus again
• Reported result:
  • The D780 is extremely good
  • Autofocus is marginally faster in the toughest situations

Z5 Test

• Uses the same general setup—notably Auto ISO.
• Uses single point / single-shot autofocus, confirmed via an audible focus beep.
• Reported behavior:
  • Slower focusing when targets are darker and lower contrast (e.g., the black statue)
  • Even in worst-case conditions, results remain usable, especially because first-dance-style wedding scenarios are often dark and don’t fully illuminate subjects

Results / Conclusions from Wedding Samples

• The reviewer examines actual Z5 wedding shots taken late in the day, including very high ISO scenarios.
• Focus vs “pixel peeping” approach: The reviewer avoids overly technical zoom-in inspection at high ISO, arguing that beyond roughly ~6400–12,000 ISO, crop/zoom quality is limited anyway; however, focus accuracy still matters.
• Main claim: In the presented sample, every photo shown was in focus (or at least not noticeably out of focus), suggesting the Z5 autofocus did not fail in real wedding use.

Z5 Image Usability Notes

Even at high ISO values (examples mentioned include 8,000 to ~10,000, 12,000, 16,000, and up to ~25,600 in the room test context), images are described as “in focus,” though not necessarily “tack sharp” technically.

D780 Comparison from the Same Wedding Period

• The reviewer claims the D780 is slightly preferred for low-light shots due to better autofocus reliability.
• At least one D780 shot is described as appearing misfocused, though the reviewer notes focus point certainty may have been unclear in the group context of the samples shown.

Takeaway

• Overall: Nikon Z5 low-light autofocus is described as “very respectable” and close to the Nikon D780.
• Verdict: The D780 has a small advantage (“hair’s breadth”) in low-light focus performance, but the Z5 remains usable for weddings and performs well in the reviewer’s real-world usage.
