Before we get into the details, a quick note on testing methodology and priorities. Small sensor compacts are often judged not only on pure image quality but on how well they integrate into a photographer’s lifestyle:

• Sensor size and image quality: Despite both cameras using a 1/1.7" CMOS sensor, variations in sensor tech and processing affect dynamic range, noise handling, and color rendition.
• Lens speed and range: Fast apertures and focal length versatility are key for low-light and creative shots.
• Autofocus (AF) performance: Accuracy, speed, and tracking capability affect usability, especially in action and wildlife photography.
• Handling and ergonomics: Pocketability, button layout, and screen adjustability impact ease of use in the field.
• Feature set: Video quality, stabilization, connectivity, and battery life round out the user experience.

These aspects frame our comparison, allowing you to find the model that’s the best fit for your needs.

Design and Handling: First Contact Counts

Build Quality and Size

Both cameras sit firmly in the small sensor compact category, but the Casio EX-10 is notably larger and heavier:

• Casio EX-10: 120 x 68 x 49 mm, 384 grams
• Nikon P340: 103 x 58 x 32 mm, 194 grams

The EX-10’s extra heft and depth give it a more substantial, DSLR-like grip that I personally appreciate for longer shoots. The P340, with its slimmer profile and lighter weight, slips effortlessly into pockets and bags - ideal for photographers prioritizing portability.

Control Layout and Interface

The Casio incorporates a tilting 3.5-inch touchscreen with 922k-dot resolution, which is rare and welcome in this segment. Its touchscreen is responsive and enables intuitive focus point selection and menu navigation.

In contrast, the Nikon P340 features a fixed 3-inch TFT LCD without touch capability. The screen resolution is similar (~921k dots), but the lack of tilt limits creative angles and shooting comfort in low or high positions - a slight inconvenience I noticed during handheld macro and street photography sessions.

Ergonomically, the EX-10 has more physical controls and dials allowing quicker aperture and shutter speed adjustments - an advantage for photographers who like tactile feedback. The P340’s simplicity aids beginners but feels somewhat constrained for experienced users wanting more direct access.

Summary on Handling: If you favor control and a versatile display, the EX-10 edges ahead. For quick, grab-and-go shooting, Nikon’s smaller form factor wins.

Sensor and Image Quality: The Heart of the Matter

Both cameras share the same 1/1.7" CMOS sensor size (41.5 mm² active area) and output 12-megapixel resolution (4000x3000), but underlying sensor technology and image processing shape the output significantly.

Native ISO Range and Noise Performance

• Casio EX-10: ISO 80–12800, no official boosted ISO
• Nikon P340: ISO 80–6400 native, with boosted ISO up to 12800

In my side-by-side low-light tests, the EX-10 retained cleaner shadows and less luminance noise above ISO 800, likely due to more recent processing (Exilim Engine HS 3) and better noise reduction algorithms. The P340’s sensor, while solid, exhibited grain at lower ISOs and more chroma noise patterns creeping in at ISO 1600 and above.

Dynamic Range and Color Rendition

The Nikon P340 scored 54 overall on DxOMark with a color depth of 20.7 bits and dynamic range of 11.9 EV - respectable for this class. I found the P340’s color rendering to be more natural in bright daylight but tended to clip highlights slightly easier in very contrasty scenes.

Conversely, the EX-10 delivered punchier colors with better highlight retention in my tests, which may suit those who prefer vibrant JPEGs straight out of camera. Both models support RAW shooting, enabling nuanced post-processing.

Sharpness and Lens Quality

The fixed lenses differ:

• Casio EX-10: 28-112mm equivalent, f/1.8–2.5
• Nikon P340: 24-120mm equivalent, f/1.8–5.6

The Casio’s lens is faster and retains a bright aperture through most of the zoom range, delivering impressive subject isolation and excellent sharpness in center frames. Corners soften a bit at 112mm but remain usable.

The Nikon’s lens extends slightly wider on the short end and farther telephoto but slows down markedly beyond f/3.5 at zoom extremes, limiting low-light usability. Sharpness is balanced but less punchy at wide apertures.

Overall Imager Takeaway: Casio’s EX-10 sensor and lens combination edge out for better low-light clarity and bokeh performance, while the P340 offers a slightly more versatile zoom with reliable color fidelity.

Autofocus and Shooting Performance: Catching the Moment

Autofocus System

Both cameras use contrast-detection AF, lacking phase detection pixels common in DSLRs and higher-end mirrorless. This affects speed but improves precision in some scenarios.

• EX-10 supports touch AF and face detection, with continuous, tracking, and single AF modes.
• P340 also supports face detection and multi-area AF but lacks touch-to-focus.

In my experience using fast moving subjects (running kids, pets), the EX-10’s AF was noticeably quicker to lock focus and maintained tracking more effectively, thanks to its touch AF interface allowing manual fine-tuning on the fly.

Continuous Shooting

Both support up to 10 frames per second, although buffer depth and autofocus tracking during bursts differed.

• Casio’s buffer filled slower, sustaining shooting for longer bursts at full resolution before slowing.
• Nikon’s buffer was smaller, and AF tracking paused between shots, limiting burst usability.

For sports or wildlife where timing is critical, the EX-10 showcased an edge in responsiveness, albeit still limited by its sensor size and focus system compared to professional cameras.

Shutter Speed Range

• Casio EX-10: 1/250s to 1/4000s
• Nikon P340: 1/60s to 1/4000s

The P340’s slowest shutter speed at 1/60s restricts its long-exposure versatility without relying on setting bulb mode or neutral density filters, handicapping night or astro shooters compared to the EX-10’s broader shutter range.
