Casio EX-FH25 vs Samsung SL620: An Expert’s In-Depth Camera Comparison for Enthusiasts and Pros

When I first got my hands on the Casio EX-FH25 and Samsung SL620, two cameras released roughly around the same period but seemingly designed for different users, I was intrigued. On paper, both cameras sport modest 1/2.3” sensors, fixed lenses, and compact designs, but the devil is always in the details. Which one suits your photography style? How do their technical specs translate into real-world performance? And can either hold its own in demanding shooting environments?

Having personally tested thousands of cameras throughout my career, I’m going to unpack these two thoroughly - covering sensor capabilities, autofocus systems, handling, image quality, and the nuances that matter across popular photography disciplines. My goal is to help you make an informed decision, aligned with your needs and budget, beyond just the spec sheet.

Let’s dive in.

Size and Ergonomics: Handling Matters More Than You Think

First impressions do count for me - a camera’s size and ergonomics affect how long you want to hold it, and ultimately, your willingness to shoot more.

Here you can see the stark difference in size between the chunky, SLR-inspired Casio EX-FH25 and the pocketable, ultracompact Samsung SL620. The EX-FH25 weighs 524g with dimensions of 122x81x83mm, while the SL620 is lighter at 168g and much slimmer at 92x61x23mm.

The EX-FH25’s bridge-style body offers a reassuring grip, with enough room to access physical dials and buttons, something I appreciate during action or wildlife shoots where quick adjustments matter. The Samsung SL620, true to its ultracompact class, sacrifices some ergonomic comfort for portability. You can tuck it into a small pocket, or pack it as a convenient travel companion.

When testing, holding the Casio felt more natural for longer sessions, especially with one-handed operation, whereas the Samsung’s very flat shape made me cautious about stability but excelled at quick snaps on the go.

Verdict: For enthusiasts who want better handling and control, the EX-FH25 shines. If minimalism and travel-friendliness top your list, the SL620 delivers.

Top Controls and User Interface: Intuitive Design for Seamless Shooting

Let’s look at how these cameras handle control layouts, which often separate a pleasant user experience from a frustrating one.

You’ll notice the EX-FH25 includes dedicated physical controls supporting shutter/aperture priorities and manual exposure modes - a rarity for bridge cameras from that era. This allows experienced photographers to fine-tune exposure quickly without digging through menus, facilitating more creative control.

Conversely, the Samsung SL620 lacks aperture/shutter priority modes and manual exposure, reflecting its point-and-shoot aim at casual users. Its control scheme is minimalist, which keeps operation simple but limits flexibility for advanced shooters.

Both cameras lack touchscreens and use fixed LCDs of similar resolution (230k dots), but we’ll talk more about that shortly.

Insights: If you rely on manual or semi-manual exposure to unlock your creative vision, the Casio’s interface is better suited. For ease-of-use and casual photography, the Samsung’s straightforward controls suffice.

Sensor and Image Quality: The Heart of the Matter

Comparing sensor specs is always the cornerstone of my camera evaluations. Both the EX-FH25 and SL620 use 1/2.3” sensors, but with different sensor technologies and resolutions.

Casio EX-FH25 packs a 10MP backside-illuminated (BSI) CMOS sensor, supporting RAW capture (a big plus!). Meanwhile, Samsung SL620 has a slightly higher 12MP CCD sensor but offers no RAW support.

Why might this matter?

• Sensor Technology: BSI CMOS sensors outperform traditional CCDs in low light and offer better dynamic range, as the EX-FH25 demonstrates. From my lab tests and practical shooting, Casio’s sensor exhibits cleaner high ISO images and deeper shadow details than the Samsung, which tends to show more noise and weaker detail in challenging light.

• Resolution: Samsung’s 12MP sensor yields larger images (4000x3000px vs. Casio’s 3648x2736px). Yet, pixel count alone isn’t everything. The EX-FH25’s larger effective sensor area (28.07mm² vs 27.72mm²) helps with signal-to-noise ratio, so its images retain clarity despite fewer pixels.

• RAW vs JPEG: The Casio’s RAW output option is crucial for photographers wanting more control over processing - especially in portrait and landscape photography where color accuracy and dynamic range matter. Samsung’s JPEG-only files limit post-processing flexibility.

Bottom line: Image quality leans in Casio’s favor, thanks to superior sensor technology and RAW support.

Screen and Viewfinder: What You See Is Key

Next, I compare the rear displays and viewfinders - your primary visual interfaces while shooting.

Both cameras have fixed 3” (Casio) or 2.7” (Samsung) LCD screens with matching 230k resolution. The EX-FH25’s larger screen aids composition and menu navigation but both lack touchscreen capabilities, meaning menu navigation can be a tad clunky.

Where the Casio stands out is its electronic viewfinder (EVF), providing a reliable alternative for composing in bright sunlight, a place where LCDs struggle. The SL620 has no viewfinder option at all, pushing you to rely solely on its LCD.

I found the Casio’s EVF handy in bright outdoor shoots - offering better framing precision and stabilization. The Samsung’s compact body trades that for extreme portability but at the cost of visibility in tough conditions.

Autofocus and Focusing Performance: Speed and Accuracy Tested

Both cameras rely on contrast-detection autofocus, but their approaches differ in sophistication and user utility.

• Casio EX-FH25: Features a single autofocus point with contrast-detection only and no continuous AF or face/eye detection. However, it offers manual focus, shutter/aperture priority, and macro modes down to 1cm - exceptional for close-up work.

• Samsung SL620: Includes face detection and multiple AF areas, improving focus accuracy on human subjects, a boon for spontaneous street or travel photography. It lacks manual focus and any continuous autofocus mode.

In real-world testing, I observed:

• The EX-FH25’s AF was quick and precise in good light on static subjects but struggled with moving targets due to no continuous AF.

• The SL620 was slower to focus on distant or low-contrast subjects but did better at locking focus on faces thanks to detection algorithms.

For wildlife or sports where fast, predictive continuous AF matters, neither camera excels. But for portraits or macro, Casio’s manual focus and closer focusing distances provide extra creativity.

Lens and Zoom: Reach and Versatility Compared

One of the EX-FH25’s major attractions is its massive 20x zoom lens ranging from 26-520mm equivalent at bright apertures of f/2.8-4.5. The Samsung offers a more modest 5x zoom at 35-175mm, with slower apertures (f/2.8-5.7).

That difference breaks down as follows:

• Casio’s zoom range enables everything from wide-angle landscapes to distant wildlife or sports shots, albeit at small sensor image quality limitations.

• Samsung’s zoom is better suited for everyday snapshots and moderate telephoto needs but lacks the reach for specialized telephoto sports or wildlife.

Image Stabilization: The Casio EX-FH25 features sensor-shift IS, helping maintain sharpness at long focal lengths or slower shutter speeds. Samsung lacks any stabilization, which will often necessitate higher ISOs indoors or in dim light.

On balance, Casio provides more flexibility for varied shooting scenarios - reflecting its bridge camera heritage.

Burst Shooting and Shutter Speeds: Capturing the Action

If you like shooting action or sports, burst rates and shutter speed ranges tell a lot.

• Casio advertises an impressive continuous shooting speed of up to 40 frames per second (fps) at reduced resolution or limited frames in full resolution mode - a feature ideal for action bursts or slow-motion sequences.

• Samsung SL620 does not specify continuous shooting capabilities, implying modest burst performance.

Regarding shutter speeds, both cover 30 seconds (long exposures) to 1/2000 seconds (fast enough for most casual uses). Casio lacks an electronic shutter option, which can sometimes freeze fast motion silently.

If action photography is a priority yet you’re working with these compact cameras, Casio’s burst advantage is a notable plus despite limited continuous AF.

Flash and Low-light Photography: How Far Can You Go?

The built-in flashes differ too:

• Casio EX-FH25 flash range is about 3.3 meters.

• Samsung SL620 offers up to 4.6 meters with several flash modes, including red-eye reduction and slow sync, giving more creative lighting control.

Neither model supports external flashes, so you’re reliant on built-in units.

When it comes to low-light performance, Casio has the edge once again:

• Its BSI CMOS sensor handles high ISO shots cleaner up to ISO 3200.

• Samsung’s CCD sensor tops out at ISO 1600 and is prone to noise.

For night, street, or indoor photography, Casio’s sensor technology, paired with sensor-shift stabilization, yields better results.

Video Capabilities: A Look Beyond Photos

Neither camera was designed as a video powerhouse, but their capabilities deserve a look:

• Casio EX-FH25: Supports several slow-motion modes - up to 1000 fps in very low resolution, 420 fps, and normal 640x480 at 30fps. Ideal for capturing fast action in experimental ways, albeit at low resolution.

• Samsung SL620: Offers up to 640x480 at 30fps, 800x592 at 20fps, but no slow-motion features.

Neither camera captures HD or 4K video, nor do they include microphone or headphone ports for audio control.

If video versatility matters, neither is compelling by modern standards - but Casio’s unique slow-motion capabilities do make it a playful choice.

Battery Life and Connectivity: Staying Powered and Connected

• Casio EX-FH25 runs on 4 AA batteries, convenient if you carry spares but less compact than lithium-ion solutions.

• Samsung SL620 uses an unspecified proprietary battery, typical for ultracompacts, with respectable life considering size.

In wireless connectivity:

• Casio supports Eye-Fi card compatibility for Wi-Fi transfer (via card), an early but limited wireless solution.

• Samsung offers no wireless connectivity.

For photo transfer or tethering workflows, neither camera excels in modern wireless features.

Durability and Weather Sealing: What About the Harsh Conditions?

Neither camera offers weather sealing or special environmental protection. Both require careful handling if you expect to shoot in wet, dusty, or rough conditions.

For serious outdoor use (landscapes, wildlife), this may be a downside - especially compared to contemporary weather-sealed mirrorless or DSLR cameras.
