• Native ISO range 100-25600; extended down to ISO 50 and boosted to 51200.
• Anti-aliasing filter included.
• Sensor area: ~856 mm² - more than twice the surface area of the Z50.

What this means practically:

• The larger full-frame sensor on the Sony A7 II provides better high-ISO performance, notably less noise above ISO 3200, which I verified during night and low-light shooting sessions.
• The A7 II delivers superior dynamic range - approximately 1 stop more than the Z50 - especially noticeable in challenging contrasty scenes like landscapes in bright sunlight and shadows.
• Resolution-wise, Sony’s slight pixel count advantage offers marginally more detail in optimal conditions; however, the Nikon’s 21 MP APS-C sensor is very capable for printing up to A3 and beyond.
• Nikon’s EXPEED 6 processor contributes to sharp color rendition, with pleasing skin tones out of the camera - a point that portrait photographers will appreciate.

In my testing, the Z50’s images impress for an entry-level model with clean, vibrant files; the A7 II’s full-frame sensor, however, remains clearly superior for demanding professionals.

Autofocus Systems: Speed, Accuracy, and Tracking

A camera’s autofocus (AF) system can make or break your shooting experience, especially in fast-paced environments.

Nikon Z50:

• 209 phase-detect AF points covering approximately 90% of the frame.
• Hybrid AF system combining phase and contrast detection.
• Eye-detection AF for humans and animals (animal eye AF works well in practice).
• Continuous shooting up to 11 fps with autofocus tracking.
• Touchscreen AF point selection on the Z50’s rear screen.

Sony A7 II:

• 117 hybrid autofocus points with phase and contrast detection.
• AF system is effective but now considered dated compared to Sony’s later models.
• Eye AF feature absent (Sony added it only in later generation cameras).
• Continuous shooting at up to 5 fps.
• No touchscreen; focus point selection via a multi-selector.

Real-world AF performance:

• The Nikon Z50’s autofocus is snappy, particularly impressive for an entry-level mirrorless. Eye and animal eye AF work well in daylight and indoor lighting.
• The Sony A7 II’s AF is reliable, especially in good light, but slower and less accurate in low light compared to newer mirrorless systems.
• The Nikon’s faster burst rates combined with 209 AF points make it better suited for casual wildlife and action.
• The A7 II still holds up for portraiture and landscape but falls behind for fast, erratic subjects.
