Examining the top control layouts, neither camera boasts advanced physical controls such as customizable dials or dedicated exposure mode buttons, reflecting their ultracompact status and entry-level positioning. However, the FujiFilm Z70’s buttons are arranged with slightly more spacing for confident thumb navigation, a subtle advantage during spontaneous shooting.

Build Quality for both cameras is typical for their class: compact plastic bodies without weather sealing or ruggedness features, thus less suited for harsh outdoor or professional environments. Neither camera offers any splash resistance, dust sealing, or shockproof features - common limitations in ultracompact cameras from this era.

Sensor Technology and Imaging Performance: Balancing Resolution vs Sensor Size

Core to camera performance is the image sensor, which largely dictates low-light ability, dynamic range, and final image quality. Both these fixed-lens ultracompacts employ CCD sensors, common around 2010-2011, but with notable differences:

Sensor size and resolution comparison illustrating notable size disparity

The FujiFilm Z70 has a considerably larger sensor area (approximately 62% larger) despite offering only a moderate resolution advantage (12MP vs 10MP). This bigger sensor surface can, in principle, capture more light per pixel area, improving image quality, especially in challenging lighting and providing better dynamic range and color depth.

In practice, cameras in this class and era both have limited high ISO performance. The FujiFilm’s ISO ceiling at 1600 is modest, with higher noise visible beyond ISO 800. The Samsung ST30’s ISO parameters are unspecified, but due to its smaller sensor, noise levels increase more rapidly, limiting low-light utility.

Both cameras include an anti-aliasing filter, important for reducing moiré but sometimes slightly softening fine detail - typical trade-offs for consumer cameras.

Raw support, an important feature for professional workflows or post-processing flexibility, is absent in both cameras, a significant limitation for advanced users wanting maximum image control.

Lens Characteristics and Optical Performance: Zoom Ranges and Aperture

Lens versatility is crucial for ultracompact cameras aimed at casual users, who benefit most from extended zooms without carrying multiple lenses.

While the Samsung ST30 advertises a higher zoom multiplier (7.5x vs. FujiFilm’s 5x), the actual focal length range is less explicit, leaving ambiguity about its widest and longest focal lengths in 35mm equivalency; lack of official data somewhat hampers direct lens comparison.

The FujiFilm Z70 offers a known focal range of 36-180mm equivalent, suitable for wide-angle landscapes to moderate telephoto portraits and casual wildlife/sports in good light. Its maximum aperture values (f/4.0 at wide and f/4.8 at tele) are relatively modest, indicating limited low-light capability and shallow depth-of-field control compared to faster fixed primes or mirrorless lenses.

The Samsung’s unspecified maximum aperture is likely similar or slightly narrower given the ultracompact design focus. Macro capabilities are explicitly detailed only for the FujiFilm, permitting close focus down to 9 cm - a practical advantage for casual macro or product photography, which the Samsung lacks or does not advertise.

Autofocus System and Shooting Responsiveness

Ultracompacts, especially from a decade ago, often had limited autofocusing systems, sacrificing speed or flexibility to reduce cost and complexity.

• FujiFilm Z70 uses contrast-detection autofocus, supporting single-shot AF and basic AF tracking. However, it lacks face/eye detection, continuous AF, or selective focus area modes - limiting for action or portraiture needing precise eye focus.
• Samsung ST30 also employs contrast-detection AF but lacks even single-shot AF confirmation at times and does not offer AF tracking or face detection.

Neither camera supports manual focus or focus bracketing/stacking, further constraining creative focusing control.

Burst shooting modes are absent or minimal, reducing suitability for fast-paced subjects in sports or wildlife photography.

In practice, the FujiFilm’s AF is noticeably quicker and more reliable under typical daylight conditions, especially given its contrast detection with simple tracking. The Samsung’s AF occasionally hesitates or hunts, particularly in lower contrast scenes.

Viewfinder, LCD Screen, and User Interface: Composing and Reviewing Shots

On-screen composition and menu navigation significantly affect usability.

Both cameras rely solely on rear LCDs without any optical or electronic viewfinder systems - a common omission in ultraportables - complicating composition in bright sunlight and stable handheld shooting.

Despite the FujiFilm Z70’s smaller diagonal, its screen offers a satisfactory viewing experience with average brightness and contrast but lower pixel density compared to the sharper Samsung ST30’s 460k-resolution display. This improved resolution makes final image previewing on the ST30 slightly clearer.

Neither camera features touchscreen capabilities or sophisticated interface designs; both employ limited button sets with menu-driven settings.

Video Capabilities: Entry-Level Motion Capture

While cameras today often emphasize video prowess, these ultracompacts have modest offerings:

The FujiFilm Z70 clearly wins in video, delivering 720p HD footage at 30fps versus the Samsung’s more rudimentary VGA quality (640x480). The lack of image stabilization in both models, however, can result in shaky handheld video, particularly noticeable at telephoto zoom and in low light.

Neither camera supports external audio input or advanced video features such as continuous autofocus during recording, limiting them to casual video capture only.

Battery Life and Storage Considerations

Neither manufacturer explicitly publishes battery life statistics; however, based on the cameras’ modest sensor sizes, fixed lenses, and limited processing demands, users can expect similarly constrained shot counts typical for compacts in this class (approximately 150-200 shots per charge).

• The FujiFilm Z70 utilizes the NP-45A Li-ion battery, a readily available and replaceable model.
• Samsung ST30 does not document battery type clearly; users must rely on proprietary batteries or integrated packs.

Both models store images on SD/SDHC cards, though the Samsung’s specification sheet does not confirm slot details explicitly, potentially complicating user expectations.
