GFX 100 II vs α7C II
af points için yan yana okuma.
af points nedir?
Autofocus points are the discrete locations on the sensor where the AF system can lock focus. Modern mirrorless bodies report point counts ranging from a few hundred to several thousand.
Why the count alone can mislead
Coverage area and detection type matter more than raw count:
- A 425-point system covering 100% of the frame outperforms a 1,053-point system covering only the center 60%.
- Hybrid phase-detect + contrast AF is faster than contrast-only with twice as many points.
What to compare
- Coverage area (% of frame).
- AF detection mode count (eye-AF for humans, animals, birds, vehicles).
- Low-light AF rating (EV value — lower is better, -6 EV is excellent).
- Continuous AF tracking frame rate.
In comparisons
For sports and wildlife, prioritize bodies with subject-recognition AF (eye-detection for the relevant subject) over raw point count.
Bu eşleşmeα7C II's 759 is roughly 79% higher than GFX 100 II's 425 (a 334 gap). Whether that gap is noticeable depends on workload — small percentage gaps rarely change day-to-day experience, while gaps of 20% or more usually do.
af points nedir?
The number of selectable autofocus zones across the frame. More points usually means denser frame coverage and finer subject-tracking granularity.
