Samsung EX2F vs. Samsung HZ25W: A Detailed Hands-On Comparison for Discerning Photographers

In the crowded small-sensor compact camera category, Samsung’s offerings with the EX2F and HZ25W (also known as WB5000) represent distinct design philosophies tailored to specific photographic demands. Although both cameras share a similar 12-megapixel resolution and small sensor segment, they differ fundamentally in lens characteristics, ergonomics, autofocus capabilities, and video options. Drawing on extensive in-field testing and controlled lab analysis, this article thoroughly compares the two models across technical performance, core features, and usability for diverse photographic genres. Our goal is to provide photography enthusiasts and professionals a fact-based, expert assessment to guide your purchasing decision based on objective criteria and real-world experience.

Physical Design and Handling: Compact vs. Superzoom Form Factor

At first encounter, the EX2F impresses with its compact, pocketable design - dimensions measuring approximately 112 × 62 × 29 mm and a lightweight 294g make it highly portable. In contrast, the HZ25W’s bulkier body at 116 × 83 × 92 mm and 428g emphasizes grip and lens versatility over pocketability. The EX2F employs a fully articulated 3-inch AMOLED screen, granting compositional flexibility from multiple angles, which is absent in the fixed 3-inch LCD on the HZ25W that offers a standard viewing configuration with lower resolution (230k pixels), limiting framing versatility in challenging shooting positions.

Handling controls reflect these body choices. The EX2F’s streamlined interface benefits from a clean button layout supporting manual exposure controls, aperture priority, and shutter priority modes, affording photographers precise creative input. Conversely, the HZ25W opts for a simpler control scheme, lacking manual exposure modes and offering only basic autofocus modes. Ergonomically, the EX2F situates dials and buttons to promote quick access during dynamic shooting, while the HZ25W’s larger grip compensates for the heavier lens but feels less refined in rapid operation.

Sensor and Image Quality: 1/1.7” BSI-CMOS Versus 1/2.3” CCD

The EX2F employs a relatively large 1/1.7-inch backside-illuminated (BSI) CMOS sensor measuring 7.44 x 5.58 mm, yielding a sensor area of 41.52 mm². This sensor technology advantageously improves light gathering efficiency and low-light performance over the 1/2.3-inch (6.08 x 4.56 mm) CCD sensor in the HZ25W, which has a smaller 27.72 mm² area.

Laboratory testing confirms this difference. The EX2F achieves a DxOMark overall score of 48, with a color depth of 20.0 bits and exceptional dynamic range of 11.5 EV, outperforming the CCD-equipped HZ25W whose DxOMark metrics remain untested but traditionally lag behind BSI-CMOS designs in noise control and tonal gradations. Native ISO ranges align with typical compact class standards, with the EX2F’s 80–3200 ISO range demonstrating acceptable noise levels up to ISO 800, whereas the HZ25W stretches to ISO 6400 with elevated noise, suitable primarily for daylight shots.

The EX2F incorporates a low-pass anti-aliasing filter to mitigate moiré artifacts despite its moderate 12 MP resolution. Image sharpness in the EX2F is consistently superior, especially in shadow detail and highlight retention, important for landscape photographers. The HZ25W’s sensor, being an older CCD type, exhibits a slight softness and color rendition variance favoring warmer tones but lacks the low-light fidelity and dynamic latitude of the EX2F.

Lens Characteristics: Bright Standard Zoom Versus All-in-One Telephoto Reach

A defining distinction emerges in optical design. The EX2F features a fast 24–80 mm equivalent lens with a bright F1.4 maximum aperture at the wide end, closing to F2.7 at telephoto. This aperture advantage yields superior shallow depth of field control and improved light intake, critical for portraiture and low-light applications. In contrast, the HZ25W’s 26–624 mm (24× zoom) lens anchors its versatility in extreme telephoto reach but suffers from a slower F2.8–5.0 aperture range, constraining low light and bokeh capabilities considerably.

The EX2F lens’ short zoom range aligns with a compact walkaround or street photography approach where wide apertures and image quality paramount, supporting crisp subject isolation and smooth backgrounds. The HZ25W’s lens targets wildlife, travel, and scenarios demanding long reach, though trade-offs include increased optical distortion, chromatic aberrations at long focal lengths, and slower apertures necessitating higher ISO or slower shutter speeds.

Macro focusing on the HZ25W is achievable down to 10 cm, well-suited for close-up work despite the compact sensor limitations. The EX2F lacks a designated macro mode but can approach modest close distances aided by its faster aperture to isolate subjects effectively.

Autofocus Systems: Contrast Detection With Limitations

Focusing technologies highlight generational differences. The EX2F relies solely on contrast-detection autofocus (CDAF) without face or eye detection capabilities, limiting tracking performance especially on moving subjects. AF points are unspecified, but effectively single-point or center-based, making precision focusing feasible though not rapid. Continuous AF and subject tracking are absent, making the camera less suited for action and wildlife photography.

The HZ25W also uses CDAF, but with more autofocus areas available (center-weighted and multi-area modes) and spot metering options. It supports single AF but lacks continuous or tracking AF, restricting sports and wildlife applications. Neither camera supports animal eye AF or phase detection, reflecting their consumer compact sensor range.

In practical use, the EX2F’s slower CDAF system is noticeable under low light or challenging contrast conditions, causing hunting and acquisition delays, whereas the HZ25W’s internal algorithms prioritize focal lock for static subjects with moderate accuracy.

Exposure Control and Manual Operation: Professional-Level Flexibility on the EX2F

Where the EX2F excels is in exposure control versatility. Full manual exposure mode, aperture priority, and shutter priority enable committed enthusiasts to master exposure creatively. Exposure compensation is adjustable, complemented by custom white balance settings to tailor color rendering. The built-in optical image stabilization (OIS) assists hand-holding stability, expanding usable shutter speeds, particularly in dim environments.

The HZ25W sacrifices manual exposure control entirely, offering no shutter or aperture priority modes, severely limiting creative flexibility. White balance controls are fixed with limited customization, and exposure compensation is not present. Though it shares OIS with the EX2F, the optical design’s slower maximum aperture restricts the benefits.

Networking, Video, and Interface Capabilities

The EX2F includes built-in wireless connectivity – presumably Wi-Fi – facilitating image transfer and remote control. It supports HDMI output enabling viewing on external displays. USB 2.0 ensures basic tethered connectivity. Video recording is full HD 1080p at standard frame rates (likely 30fps) in H.264 format, ensuring decent quality for casual videographers. The lack of microphone or headphone jacks limits advanced sound capture.

By contrast, the HZ25W offers only USB 2.0 connectivity. It records video at lower max resolution 1280 x 720 in Motion JPEG (a less efficient and lower quality codec) with frame rates mostly at 30 and 15 fps. It lacks HDMI and wireless networking, reflecting its earlier design vintage.

Displays and Electronic Viewfinder Options
