Sensor and Image Quality: Small Sensor vs Full Frame

The Olympus SP-620 UZ employs a 1/2.3-inch CCD sensor with a resolution of 16MP. This sensor is physically small (6.17x4.55mm, ~28mm²), typical in superzoom compacts to enable extreme focal lengths at low cost, but it inherently limits image quality. CCD technology, once praised for color rendition, now trails CMOS alternatives in low light and dynamic range.

In contrast, the Panasonic S1H’s sensor is a full-frame 35.6x23.8mm (847mm²) CMOS unit with 24MP resolution. Leveraging the latest Venus Engine processor, it delivers outstanding detail, low noise, and dynamic range, making it a versatile performer from shadows to highlights.

Real-World Testing Highlights:

• The Olympus’s small sensor struggles in low light above ISO 400-800, exhibiting noise and loss of detail. High ISO performance limits night and indoor photography.
• The Panasonic shines with usable ISO up to 6400 and beyond, with impressive tonal gradation suitable for professional post-processing and large prints.
• Dynamic range in Panasonic allows capturing complex landscape scenes without blown highlights or crushed shadows, an area where the Olympus’s limited sensor capacity shows weakness.

Summary: Sensor size and modern technology substantially favor Panasonic’s S1H for image fidelity, low-light resilience, and tonal flexibility. Olympus remains suitable for bright daylight and casual snapshots.

Lens and Zoom: Versatility on a Spectrum

The Olympus SP-620 UZ features an integrated superzoom lens covering 25-525mm equivalent (21x zoom) with a modest maximum aperture range of f/3.1–5.8. This enormous reach makes it appealing for travel or wildlife novices who want to get close without swapping lenses.

The Panasonic S1H accepts Leica L-mount lenses - an evolving system encompassing over 30 professional-grade lenses from Panasonic, Leica, and Sigma. Focal length options span ultra-wide to super-telephoto and specialized optics like macros and tilt-shifts.

What I found in field tests:

• Olympus’s huge zoom range delivers incredible framing flexibility, yet image quality diminishes noticeably at long ends due to diffraction and optical compromises inherent in tiny sensor compacts.
• Panasonic’s quality lenses offer razor-sharp corner-to-corner resolution, excellent bokeh control, and fast apertures enabling shallow depth-of-field effects critical for portraits or low-light work.
• The S1H’s manual focus, focus peaking, and focus stacking assist with precise macro and creative focus control - options Olympus can’t match.

Summary: Olympus is a no-lens-changing travel companion with long reach but limited optical quality. Panasonic offers superior glass and creative versatility for professional ambitions.

Autofocus Performance and Usability

Autofocus systems differ profoundly between these two models.

The Olympus SP-620 UZ uses a contrast-detection AF system with face detection but no phase detection or advanced tracking capabilities. Single AF mode and no manual focus limit framing finesse.

The Panasonic S1H incorporates a sophisticated 225-point contrast-detection AF with face and eye detection, touch-to-focus, and continuous tracking designed for fast action and video.

During my wildlife and sports trials:

• Olympus’s AF proved adequate for static subjects, but hunting focus outdoors or on moving targets caused frequent hunting and missed shots.
• Panasonic locked focus reliably on moving subjects, smoothly tracked faces and eyes, and autofocus performance in video mode ran seamlessly - even in low light.

Summary: Panasonic performs solidly for fast-moving subjects and video work; Olympus best serves casual users and static scenes.

Display and Viewfinder: Composition and Playback

The Olympus’s fixed 3-inch 230k-dot TFT LCD is functional but small and dim, challenging under bright sunlight or when composing tricky angles.

In contrast, Panasonic offers a large 3.2-inch fully articulating touchscreen with 2.33 million dots - bright, color-accurate, and touch-responsive, ideal for live view shooting in complex scenes or vlogging. It even supports a top status LCD for at-a-glance info.

(While this image primarily shows top controls, the Panasonic S1H's electronic viewfinder with 5.76 million dots provides stunning clarity, high magnification (0.78x), 100% coverage, and an immersive shooting experience. Olympus lacks viewfinder options entirely.

Summary: The Panasonic’s displays and viewfinder emerge as a joy for precise composition, while Olympus delivers minimal essential functionality.

Portability and Battery Life: On the Go Considerations

Olympus SP-620 UZ uses four AA batteries - practical for travel and quick swapping but can be heavy and wasteful over long shoots. Its compact size and light weight suit casual strolls and holidays.

By comparison, the Panasonic S1H employs a proprietary battery pack rated around 400 shots per charge - typical for full-frame mirrorless. Its larger body and lens systems significantly increase your gear load but provide professional reliability.

Connectivity-wise, Olympus offers Eye-Fi wireless card support, USB 2.0, and HDMI output - rudimentary but helpful. Panasonic builds in Wi-Fi, Bluetooth, full-size HDMI output, microphone and headphone jacks - crucial for serious video production and remote camera control.

Summary: Olympus excels at lightweight portability and quick battery swaps; Panasonic serves professionals with longer shooting endurance and advanced connectivity.
