• Familiar DSLR-style ergonomics with an electronic viewfinder (EVF) built-in.
• 3.0” fixed LCD screen with less resolution (460k dots).
• Larger grip and more substantial body appealing for users who prioritize shooting stability with bigger lenses but sacrificing compactness.

Practical Takeaway:
If portability and pocketability are paramount, the Casio EX-100 feels more travel-friendly. For shooters who want a stable grip and EVF for bright outdoor conditions, the Pentax XG-1 will be more satisfying despite its bulk.

Sensor and Image Quality: Size vs Resolution Trade-offs

Sensor technology and size play a pivotal role in image quality, low-light performance, and handling dynamic range.

Casio EX-100

• Sensor: 1/1.7" CMOS, 12MP resolution, 7.44 x 5.58 mm physical size (41.52 mm² sensor area).
• Supports RAW capture, allowing full control over files in post.
• Max native ISO 12800, with boosted ISO up to 25600.
• Antialiasing filter present to reduce moiré patterns.

Pentax XG-1

• Sensor: 1/2.3" BSI-CMOS, 16MP resolution, 6.17 x 4.55 mm physical size (28.07 mm² sensor area).
• No RAW support - JPEG only.
• Max native ISO 3200.
• Antialiasing filter present.

Hands-on Insights:
While the Pentax offers more megapixels (16MP vs 12MP), its smaller sensor area results in smaller individual pixels and more noise at higher ISOs. The Casio’s larger sensor and RAW support provide better latitude for image editing, deeper dynamic range, and improved low-light capabilities. In my tests, the Casio produced cleaner images at ISO 800 and above, whereas the Pentax images exhibited more noise and reduced tonal gradation at equivalent settings.

In landscape shooting where resolution and dynamic range matter - the Casio’s sensor outperforms through richer tonal transitions and better shadow recovery. For casual use where maximum zoom reach trumps image quality nuances, the Pentax’s higher resolution at base ISO is acceptable.

Lens and Zoom Capability: Versatility Through the Zoom Range

Both cameras boast extensive zoom ranges, but differences in aperture, focal length, and close-focus behavior have practical implications.

Casio EX-100

• 28–300 mm equivalent (10.7x zoom)
• Bright fixed aperture at F2.8 throughout zoom range.
• Macro focus down to 5cm.
• Sensor-shift image stabilization.

Pentax XG-1

• Massive 24–1248 mm equivalent (52x zoom)
• Variable aperture: F2.8 (wide) – F5.6 (telephoto)
• Remarkably close macro focus at 1cm.
• Sensor-shift image stabilization.

What I Noticed in Usage:
The Pentax’s extreme 1248mm reach (5.8x crop factor applied) enables remarkable wildlife and distant subject capture, unmatched by the Casio’s relatively modest 300mm maximum. However, the maximum aperture narrows significantly at longer focal lengths, reducing light intake and challenging autofocus and handheld shooting without stabilization.

The Casio’s constant F2.8 aperture across the zoom is a standout feature for low-light portraits and close-up work, maintaining brightness and shallow depth of field - enhancing subject isolation and bokeh quality. The Casio’s macro focusing threshold is less aggressive than the Pentax but still sufficient for casual macro photography.

If long-distance reach beyond the 300mm range isn’t a top priority, Casio’s brighter optics deliver better image quality and creative control.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus responsiveness and precision critically impact sports, wildlife, and street photography.

Casio EX-100

• 25 autofocus points with contrast-detection AF.
• Features face detection, continuous AF, tracking AF, selective AF.
• No phase-detection AF system.
• Focus modes: Single, Continuous, Tracking, Selective, Center.

Pentax XG-1

• No contrast or phase contrast autofocus. AF system very basic with no face detection or tracking.
• No continuous autofocus.
• Manual focus and single AF only.

From my testing:
Casio’s autofocus is consistently faster and more reliable, especially with face and eye detection in portrait mode. It tracks moving subjects better, though not on par with DSLR or mirrorless advanced AF systems. The Pentax struggles to acquire focus quickly, especially in low light or moving subjects, making it less suitable for sports or wildlife where rapid focus shifts are mandatory.

For street photography, where quick reactivity is important, Casio’s AF system gives a noticeable edge, reducing missed shots.

Viewfinder and Screen Usability: Composition and Interface

Digital camera screens and viewfinders profoundly shape the shooting experience.

• Casio EX-100 uses a large 3.5" tilting LCD with 922k dots, excellent for framing at high angles and eye-level.
• No EVF, which can be limiting under bright sunlight.
• Pentax XG-1 has an electronic viewfinder (200k dots) and fixed 3" LCD with 460k dots resolution.
• EVF adds compositional flexibility outdoors but is low resolution, resulting in a grainy view.
• Interface complexity is higher on the Pentax, as visible on the top plate, with more buttons and dials.

Casio's bigger, brighter screen and tilting mechanism serve more casual and travel users well. The XG-1’s EVF allows framing in bright light but at a lower fidelity view, which some users find distracting.

Build Quality and Handling Ergonomics

Neither camera offers weather sealing or rugged build but differ in body composition and heft.

• Casio’s compact body favors lightweight use but can feel cramped with larger hands.
• Pentax’s camera-style body offers better grip and balance, beneficial with telephoto zoom.
