• Crop factor approx. 5.8x, limiting background blur and depth of field control
• No image stabilization
• JPEG only, no RAW support, which limits professional editing potential

Practical Impact:

• Image Resolution & Detail: The Z6 II’s full-frame sensor delivers sharply detailed, well-resolved images with excellent noise control in low light. The WG-2’s small sensor is fine for casual use but will exhibit more noise in shadows and limited dynamic range.
• Depth of Field & Bokeh: Thanks to sensor size and lens speed, the Nikon achieves beautiful background blur, ideal for portraits and artsy shots. The Pentax’s small sensor and fixed lens mean everything is typically sharper front-to-back but less subject-background separation.
• Low-light Shooting: The Nikon’s extended ISO range and stabilization offer flexible shooting at night or indoors. The WG-2's high ISO capability is limited and noisier, making it less suited for darkness or astrophotography.

LCD and Viewfinder: Seeing Your Shot in Bright or Low Light

How you preview your framing and settings matters greatly.

• Nikon Z6 II:

  • 3.2-inch fully tilting touchscreen LCD (2100k dots)
  • High resolution electronic viewfinder (3690k dots, 0.8x magnification, 100% coverage)
  • Touch functionality for AF point selection and menu navigation
  • The EVF is bright and fast, essential for action and low-light negotiations

• Pentax WG-2 GPS:

  • 3-inch fixed LCD screen with 460k dots
  • No built-in EVF; relying only on LCD for composition
  • No touchscreen
  • Good outdoor visibility thanks to anti-reflective coating but less versatile in harsh sunlight or nighttime

My Experience: In bright daylight, the Nikon’s EVF and tilting, high-res touchscreen give you flexible shooting angles and confident framing. The WG-2’s LCD is straightforward but can frustrate in tricky lighting due to its lower resolution and fixed position. The lack of viewfinder means eye-level shooting is not an option.

Autofocus and Shooting Speed: Catching the Action and the Moment

Speed and accuracy in focusing and capturing frames define your success in sports, wildlife, and fleeting street scenes.

Nikon Z6 II:

• Advanced hybrid AF system with 273 focus points using phase and contrast detection
