Neither camera provides a touchscreen interface, which impacts menu navigation fluidity, particularly on the PX’s lower-resolution 2.7-inch display.

Sensor Architecture and Image Quality Assessment

The imaging sensors present one of the most consequential differentiators. Both employ a 1/2.3-inch sensor size measuring 6.17x4.55 mm with a surface area of approximately 28.07 mm²; however, the Casio utilizes a CMOS sensor, whereas the Ricoh is paired with an older CCD sensor technology.

From technical bench evaluations and practical shooting tests under varying ISOs and lighting conditions, the CMOS sensor in the EX-ZR700 delivers superior noise performance and dynamic range. This translates to cleaner images at high ISO settings (up to ISO 3200 native) and enhanced retention of highlight and shadow details - critical for landscape or indoor photography.

In contrast, the Ricoh PX’s CCD sensor, while still capable of producing vibrant color rendition for daylight scenarios, exhibits a steeper noise gradient at elevated sensitivities, limiting effective use beyond ISO 800. Additionally, the CCD sensor’s tendency to introduce blooming and reduced responsiveness under continuous shooting constrains its versatility for fast-paced genres such as sports or wildlife.

Both sensors employ anti-aliasing filters to mitigate moiré artifacts; while beneficial, this marginally softens resolution fidelity. Overall, the EX-ZR700’s CMOS sensor framework positions it ahead in image quality metrics relevant to advanced users.

Lens Specifications and Optical Performance

The fixed lens assemblies define the cameras’ compositional reach and dictate optimal use cases.

• Casio EX-ZR700: 25-450 mm equivalent focal length, 18x zoom, aperture range F3.5 (wide) to F5.9 (telephoto).
• Ricoh PX: 28-140 mm equivalent focal length, 5x zoom, aperture range F3.9 (wide) to F5.4 (telephoto).

The EX-ZR700’s extensive telephoto reach offers significant advantages for wildlife and sports photography, where distant subject capture is paramount. However, the narrower maximum aperture at longer focal lengths marginally hinders low-light performance and depth-of-field control compared to lenses with wider apertures.

Ricoh’s PX lens, with a shorter zoom range, caters more suitably to general-purpose snapshots, street photography, and moderate telephoto needs. Its slightly faster aperture at the tele-end can facilitate mildly better background separation, though its 5x zoom range significantly limits framing flexibility for distant subjects.

Both lenses support macro capabilities - 5 cm minimum focus distance on the Casio versus 3 cm on the Ricoh - rendering the PX more adept at close-up detail work, particularly for macro enthusiasts prioritizing precision focus and subject proximity.

Autofocus Systems and Focusing Performance

Autofocus (AF) efficacy remains critical across many photography disciplines. The EX-ZR700 employs contrast-detection AF with face detection and tracking, supplemented by center-weighted and multi-area AF modes. Continuous AF is unavailable, but tracking AF exists, assisting subject retention during video or burst capture.

Conversely, the PX features a basic contrast-detection AF system, with single and tracking AF modes, and face detection capabilities. The PX lacks continuous AF, and focus area control is limited.

Real-world testing shows the EX-ZR700’s autofocus system to be moderately quicker and more reliable, especially under moderate to low light. The Casio’s AF algorithm better maintains focus on moving subjects and adapts swiftly to changing scene contrast, contributing to improved sports and wildlife handling.

Neither camera includes phase detection autofocus (PDAF), which precludes the speed and precision typical in more advanced interchangeable-lens systems. Users requiring fast-moving subject tracking or eye detection autofocus may find these fixed-lens compacts limiting.

Display and Viewfinder Experience

Neither model offers electronic viewfinders (EVF), so reliance on rear LCDs is mandatory. The EX-ZR700’s 3-inch “Super Clear” TFT LCD sports a 922k-dot resolution providing sharp, bright image previews. This aids composition clarity, focusing accuracy, and menu navigation.

The Ricoh PX’s 2.7-inch display has a significantly lower 230k-dot resolution, which hampers precise framing and fine detail inspection. This resolution deficit challenges photographers working in bright sunlight or requiring critical manual focus assessment.

Both displays are fixed, with no articulation or touchscreen affordances, limiting flexibility in various shooting positions, such as low-angle macro or high-angle street photography.

Continuous Shooting, Shutter Speeds, and Video Capabilities

Burst shooting and shutter control impact the cameras’ suitability for action genres. The EX-ZR700 supports continuous shooting at 3 frames per second (fps) up to an unspecified buffer, while the PX is limited to a pedestrian 1 fps.

Shutter speed ranges on both cameras max out at 1/2000 sec; the EX-ZR700’s minimum shutter speed extends to 4 seconds, compared to 8 seconds on the PX, rendering the Casio slightly more favorable for long exposure and night photography.

Video recording capabilities differ markedly:

• Casio EX-ZR700: Full HD 1080p at 30 fps, with additional slower frame rates for high-speed capture (up to 1000 fps in reduced resolution modes), and MPEG-4/H.264 codecs.
• Ricoh PX: HD 720p at 30 fps with Motion JPEG format.

The EX-ZR700’s advanced video modes provide greater creative freedom, including slow-motion effects, superior resolution, and higher compression efficiency, enhancing usability for hybrid photo-video shooters.

Neither camera offers external microphone or headphone ports, limiting professional audio control. Also, no image stabilization distinction beyond sensor-shift internal stabilization in both models indicates similar corrective performance.
