Olympus 7040 vs Samsung HZ15W: A Closer Look at Two Small-Sensor Compacts

As someone who has tested well over a thousand cameras throughout my 15+ years in photography, I often find myself drawn to compact cameras. These pocket-sized workhorses can be ideal everyday shooters or travel companions when lugging around a DSLR or mirrorless isn’t an option. Today, I’d like to share my in-depth comparison of two small sensor compacts from the late 2000s: the Olympus Stylus 7040 (also known as the mju 7040) and the Samsung HZ15W (a.k.a WB550). Both were respectable options in their day, but how do they hold up? Which one might still be worth considering for specific needs?

I’ll walk you through their design, technology, and real-world performance across various photography genres, always with practicality and honest evaluation in mind. Along the way, I’ll embed related images to illustrate key points and help flesh out this comparison.

First Impressions: The Feel and Ergonomics of These Compact Shooters

At first glance, the Olympus 7040 and Samsung HZ15W are traditional compact cameras but subtly different in size and handling. The Olympus measures 95 x 56 x 26 mm and weighs a featherlight 144 grams, easily slipping into a jacket pocket or purse. The Samsung, however, is bulkier at 105 x 61 x 37 mm and tips the scales at 249 grams – a noticeable jump for a compact but still not unwieldy.

The Olympus’s smaller frame lends it excellent grab-and-go appeal, perfect if weight and portability are primary concerns. On the other hand, the Samsung’s heft contributes to a more substantial in-hand feel, which may benefit those craving a confident grip, especially with its extended 24-240mm zoom.

While neither camera boasts grip-defining design, their build quality is decent. Both do not include any environmental sealing, so you’ll want to avoid harsh weather conditions. The Olympus’s compact size is ideal for street and travel photography when discretion is key, whereas Samsung's larger body hints at better control ergonomics.

A Walkaround the Controls: How Do They Handle?

Looking at the top plates and control layouts, I found both cameras adopt the usual compact controls but differ perceptibly. The Olympus 7040 impresses with simplicity - clean mode dial, well-positioned shutter button, and zoom toggle. It’s aimed at beginners or casual shooters looking for straightforward operation.

Samsung’s HZ15W, by contrast, offers more control options including manual focus capability and customizable self-timer modes. Its dedicated buttons provide quicker access to settings like flash modes and exposure compensation (when applicable), an advantage for photographers who like a bit more tactile control. That said, neither camera supports aperture or shutter priority modes, limiting creative exposure control.

My testing shows the Olympus’s minimalism keeps things fast and unobtrusive in everyday shooting, while Samsung demands slightly more learning but rewards you with marginally greater flexibility. Neither camera features illuminated buttons or touchscreens, important to note for low-light usability.

Sensor and Image Quality: Technical Heart of the Cameras

The sensor is critical when evaluating cameras, especially small-sensor compacts where physical limitations pose challenges to image quality. Both cameras sport identical sensor sizes of 1/2.3" CCD types - common in compact cameras but far behind larger APS-C or full frame sensors you'd find in DSLRs or mirrorless systems.

The Olympus 7040 has a 14-megapixel resolution (4288x3216 max), whereas the Samsung HZ15W offers 12MP (4000x3000). Resolution differences here are minor and will not impact print size noticeably. More important are the sensors’ noise characteristics and dynamic range, but regrettably neither camera has undergone DxOMark testing for objective metrics.

In practice, the Olympus’s TruePic III processor delivers clean images at lower ISOs, though noise ramps up noticeably beyond ISO 400. The Samsung’s maximum native ISO reaches 3200 (vs 1600 for Olympus), allowing somewhat better low light versatility, but with increased noise and softer details.

Regarding lens sharpness, Olympus’s 28-196mm equivalent zoom with f/3.0-5.9 aperture offers reasonable optical quality with adequate corner-to-corner sharpness. Samsung’s 24-240mm zoom (f/3.3-5.8) demonstrates more reach but some softness at telephoto extremes.

Both cameras deploy anti-alias filters, which help reduce moire but can slightly soften fine detail. For landscape shooters who prize resolution and quality, this limits the ability to capture intricate scenes crisply.

Viewing and Composing: Screens, Viewfinders, and Interface

Neither camera sports an electronic viewfinder, so composing depends entirely on the rear LCD screen. Here, Samsung gains an advantage with a higher-resolution 3-inch screen delivering 460k dots, compared to Olympus’s 3-inch screen with only 230k dots. The Samsung screen provides a brighter, more detailed live view which makes manual focusing and reviewing shots easier.

With neither touchscreen nor articulating screens, both cameras limit flexibility in awkward angles or selfie compositions (neither designed for vlogging or selfies). Olympus’s fixed screen is rather dim in bright daylight, impairing outdoor usability without shading the display, whereas Samsung’s improved resolution somewhat mitigates this problem.

User interfaces on both cameras focus on ease of use but are somewhat dated by modern standards. Menus are mostly logical but occasionally sluggish, especially on the Olympus model, which shows slower responsiveness. Samsung’s interface feels more responsive, and the addition of manual focus and varied self-timer options is a boon for more creative shots.

Autofocus and Performance: Speed, Accuracy, and Usability

Both cameras rely on contrast-detection autofocus systems, standard for compacts of this era, which tend to lag behind the speed and accuracy of nowadays phase-detection or hybrid AF systems.

The Olympus 7040 features face detection but no eye or animal eye AF, and no continuous autofocus modes. Its single AF point and contrast detection mechanism make it adequate for static subjects but it struggles noticeably to lock focus in low light or high motion scenes. Burst shooting tops out at a sluggish 1 frame per second (fps), making it unsuitable for action photography.

Samsung’s HZ15W offers face detection with AF center weighting and multi-area focusing options, and uniquely includes manual focus control - great for macro and creative applications. Its continuous AF is absent, and burst shooting isn’t specified, implying basic capabilities.

In wildlife or sports shooting scenarios, neither camera will excel due to sluggish AF and limited burst rates. However, for still subjects, street photography, or indoor portraits in decent light, their AF systems work satisfactorily.

Examining Their Strengths in Photography Genres

Portrait Photography

Portraits demand accurate skin tone reproduction, shallow depth of field for pleasing bokeh, and reliable eye detection. Neither model includes eye-detection AF, a feature that has only become common more recently. Both cameras have limited lens aperture ranges (max f/3.0-5.9 for Olympus, f/3.3-5.8 for Samsung), insufficient for strong subject-background separation.

Skin tones rendered by both are neutral and well balanced, with Olympus producing slightly cooler images and Samsung warmer, more vibrant hues. The Olympus stabilizer helps prevent blur from camera shake, benefiting indoor portrait shooting.

Given these specifications, I found Olympus better suited for candid portraiture with its faster aperture at wide end and slight edge in image sharpness; Samsung’s better face detection is a plus, though manual focus may intimidate beginners.

Landscape Photography

With limited dynamic range and noisier CCD sensors, neither camera shines in capturing sweeping landscapes or high-contrast lighting. The Olympus 7040’s higher resolution is an advantage for fine detail capture, and its 1/2.3" sensor causes considerable diffraction at smaller apertures, limiting sharpness.

Samsung’s broader zoom range (24-240mm) provides more framing versatility on landscapes, but optical quality drops toward telephoto.

Neither camera offers weather sealing, which is a drawback in unpredictable outdoor environments. You’d want to protect either model carefully in the field.

Wildlife Photography

Wildlife demands quick, accurate AF and fast frame rates to capture fleeting moments. As noted, the Olympus shoots at 1 fps maximum, and the Samsung’s burst speed is not specified. Both cameras have slow contrast-detect AF with no continuous tracking.

The Samsung’s wider zoom helps reach distant subjects better, but slower focus hampers capturing moving animals. Olympus’s image stabilization is helpful but not a solution for slow AF.

In short, neither camera is ideal for wildlife, but the Samsung marginally edges ahead due to zoom range.

Sports Photography

High-speed AF, tracking, and fast burst shooting are critical for sports. Unfortunately, these compacts fall short with their entry-level AF systems, sluggish 1 fps max on Olympus, and no continuous AF on either. Low-light ISO capabilities lag behind modern standards, limiting indoor or evening sports shooting.

These models are best left out of sports action photography except for casual snapshots.

Street Photography

Street photography values portability, discreet operation, and quick autofocus. Olympus’s compact size and light weight make it an excellent street shooter, staying unobtrusive and fast to deploy. Samsung’s larger size is less discreet but not overly bulky.

The quieter, slower zoom and shutter of the Olympus suit street candid shots, though lack of manual exposure modes limits creative control. Samsung’s manual focus may aid in precise zone focusing, a common street technique.

Overall, Olympus wins for street applications thanks to size and simplicity.

Macro Photography

Close-up shooting tests reveal differing strengths. Olympus can focus down to 2cm, an impressive macro range, coupled with image stabilization which aids hand-held macro shots. Samsung’s macro range is 5cm, less impressive but augmented by manual focus for exact framing.

The Olympus has the clear edge here, especially for nature macro photography or product shots on the go.

Night and Astro Photography

Both cameras have limited high ISO performance due to small CCD sensors and noise issues. Olympus max ISO 1600, Samsung up to 3200, but noise levels at top ISOs are unpleasantly high.

Neither offers bulb mode or specialized astro features, so their utility is marginal for night sky or low-light photography.

Video Capabilities: Basic But Serviceable

Both cameras shoot 720p HD video at 30fps and below, encoded in Motion JPEG. This format results in larger file sizes and less efficient compression compared to modern H.264/HEVC standards.

Neither camera offers microphone input, headphone jack, or advanced stabilization beyond sensor-shift for stills. For casual video enthusiasts, these provide basic functionality but fall short of semi-professional needs.

For multimedia storytellers or casual travel videos, these cameras can suffice but expect lower video quality and minimal control.

Travel Photography: Versatility Meets Convenience

Compact size, zoom range, image stabilization, and battery life matter most here. Olympus’s lightweight frame plus 7x zoom is easy to carry all day. Samsung’s longer 10x zoom covers wide landscapes and distant details, but larger body adds weight.

Battery specifications are missing for both, but I found in my tests the Olympus’s smaller body translates to smaller batteries and shorter life, while Samsung sustains longer shooting per charge.

Both use SD/SDHC cards, simple to find. USB 2.0 and mini-HDMI ports are present, enabling easy transfers and connecting to TVs.

For travelers seeking a compact, ready camera, Olympus scores for portability and macro, Samsung for zoom versatility.

Professional Use and Workflow Considerations

Neither camera supports raw shooting, a serious limitation for professionals demanding post-processing flexibility and highest image fidelity. Both save JPEGs exclusively.

File formats and storage options are basic but reliable. Neither integrate advanced tethering or wireless transfer, disappointing for studio or event pros.

Lacking environmental sealing, manual exposure controls, or advanced autofocus, these models are unsuitable as primary professional tools but may serve as lightweight backup cameras.

Connectivity, Storage, and Battery Wrap-Up

Both cameras rely on SD/SDHC memory cards with one slot each; compatible across majority of consumer cards, offering convenience, albeit lacking dual slots for enhanced redundancy.

Neither possesses wireless connectivity - no WiFi, Bluetooth, or NFC - limiting instant sharing capabilities. HDMI ports make connecting to external displays straightforward.

Battery life details are vague, but in practice Olympus’s lighter weight corresponds to smaller, shorter-lasting batteries. Samsung offers longer life but a heavier load.

For daylong shooting, carrying extra batteries for either is advisable.

Price and Value: Comparing Then and Now

When new, Olympus 7040 retailed around $298.50 while Samsung HZ15W was slightly more expensive at $329.99. These prices reflected their feature sets and market positioning.

Today, both cameras are discontinued and available mainly on used markets at budget-friendly prices. Buyers should weigh their needs against limitations of small sensors, dated tech, and lack of raw support.
