Olympus SP-810 UZ vs Pentax Efina: An Expert’s Take on Two Compact Contenders

In a market saturated with compact cameras, two models stand out for contrasting reasons: the Olympus SP-810 UZ, a bridge-style superzoom announced in mid-2011, and the Pentax Efina, an ultracompact model introduced in 2013. While both cameras promise portability and ease of use, they cater to very different photographic needs and styles. Having tested thousands of cameras over the past 15 years, I’m excited to share my detailed hands-on experience comparing these two unique offerings.

This comparative review digs deep into technical features, ergonomic design, real-world imaging capabilities, and value - the kind of expertise you need before investing your hard-earned money. Whether you’re a casual shooter, a travel photographer, or seeking an affordable second camera, the insights here will help you understand how these cameras perform in various genres.

A Tale of Two Sizes: Ergonomics and Handling

At first glance, the Olympus SP-810 UZ and Pentax Efina couldn’t be more different in terms of physical size and presence. The SP-810 UZ is a bulky bridge camera with an SLR-like body, measuring approximately 106 x 76 x 74 mm and weighing in at 413 g. In stark contrast, the Pentax Efina is a pocket-friendly ultracompact device - just 87 x 54 x 21 mm and a mere 91 g.

From hands-on testing, it’s clear the SP-810 UZ was built for photographers who need a versatile zoom and solid grip without the bulk and expense of interchangeable lenses. The dead-weight feel of the EFina, while incredibly portable, can get lost in a large hand. Its ultra-slim body translates to less physical control but compensates by being nimble and extremely pocketable.

If you prioritize holding comfort and direct manipulation of controls during extended shoots, the Olympus’s more substantial build (including a mild ergonomic thumb rest) will directly elevate your experience - especially for telephoto or landscape work. The Efina’s charm lies in discreet street photography and casual snaps where minimal intrusion matters.

Control Layout and Interface: Where Function Meets Form

While the Olympus SP-810 UZ’s heft affords a more detailed control suite, the Pentax Efina embraces minimalism. The top plate and button arrangement on the SP-810 UZ integrates classic exposure essentials in an SLR-like layout, with a mode dial and easily accessible playback and zoom toggles.

This layout gives the Olympus an edge in quickly switching modes or adjusting settings in the field - a critical advantage for enthusiasts who want to capture fleeting moments without fumbling. The Pentax Efina, designed with simplicity in mind, offers fewer physical controls, relying heavily on its menu system. It lacks manual exposure modes and offers only one shutter speed priority limit, which can frustrate advanced users seeking greater creative input.

From an experienced perspective, the Olympus’s control design will feel more intuitive and responsive, especially during dynamic shooting sessions such as sports or wildlife. The Pentax is better suited for those who prioritize simplicity and immediate use over granular command.

Sensor Size and Image Quality: Beyond the Megapixel Count

Both models employ a 1/2.3” CCD sensor - the same dimensions and roughly the same physical sensor area (6.17 x 4.55 mm) - with a resolution of 14 megapixels. That said, sensor size alone doesn’t tell the whole story. Variations in sensor technology, image processor, and lens optics heavily influence final image quality.

Olympus utilizes their TruePic III+ image processor, providing decent noise reduction and color rendering, although the CCD sensor technology is aging by today’s standards. The SP-810 UZ enables native ISO sensitivity from 80 up to 3200, with some control over noise at lower ISOs. However, the highest ISO results exhibit significant grain and color loss.

Conversely, Pentax’s Efina limits its max native ISO to 1600, which helps preserve image detail but constrains low-light potential. Its image processor and sensor combination deliver respectable color fidelity but tend toward softer images when zoomed in, especially toward the tele end.

In my bench tests and field shooting, the Olympus generally produces sharper, more vibrant images with better low-light versatility - not surprising given its longer zoom and marginally faster lens aperture at the wide end (F2.9 vs F3.5). However, both cameras struggle with dynamic range and noise compared to more modern rivals.

LCD and Viewfinder Experience: Composing Your Shot

Neither camera features an electronic viewfinder, opting instead for rear LCD-only interfaces for live preview and menu navigation. This choice hinders usability in bright outdoor conditions.

The Olympus SP-810 UZ sports a fixed 3-inch screen with 230k-dot resolution, similar in pixel density to the Efina’s 2.5-inch fixed QVGA TFT LCD. The extra size on Olympus’s screen makes framing easier, particularly when composing at telephoto focal lengths.

The SP-810 UZ’s display handles colors more faithfully and has better viewing angles. Conversely, the Pentax screen feels a bit cramped, and reflections become an issue outdoors. Neither camera offers touch functionality here, limiting quick menu access and focus adjustments.

Through real-world usage, I found the lack of any viewfinder a significant ergonomic drawback, especially with the SP-810 UZ’s long zoom, where holding the camera away from the face makes it harder to stabilize shots. The Efina’s compact form partly offsets this by encouraging quick, snapshot-style captures.

Zoom and Optics: How Much Reach Do You Really Need?

If you’re a zoom enthusiast, this is where the Olympus shines. Its 36x optical zoom lens spans a formidable 24-864mm (35mm equivalent) focal length range with an aperture varying from F2.9 to F5.7. This beast of a zoom allows photographers to explore everything from wide-angle travel landscapes to distant wildlife or even detail-rich sports images - albeit within the limits of the sensor’s resolution and autofocus.

Pentax’s Efina offers a more modest 5x zoom range, covering 26-130mm at F3.5-6.3 aperture, which focuses it clearly on everyday use and casual portrait or street photography.

From a technical standpoint, longer zooms typically suffer from optical compromises - distortion, softness, chromatic aberration - but Olympus’s multi-element lens design mitigates many issues satisfactorily at mid-zooms and below. The EFina delivers clean optics but lacks reach, limiting framing options for telephoto subjects.

Autofocus and Shooting Performance: Speed and Accuracy in the Field

The Olympus SP-810 UZ incorporates contrast-detection autofocus with face detection capabilities and several AF area configurations. While not blazing fast by modern mirrorless or DSLR standards, it generally locks focus accurately in daylight and moderate lighting conditions. Unfortunately, autofocus slows considerably during video recording or in low light, limiting usability for action scenarios.

Pentax Efina has more limited autofocus features, lacking continuous or touch autofocus modes. It does implement contrast detection and face detection, but slow reaction times and hunting are noticeable under dim conditions.

Continuous shooting speeds highlight another difference - Olympus offers 0.7 fps, which is certainly not sports-grade but acceptable for casual bursts. The Efina’s continuous shooting information is not specified clearly, suggesting limited or no continuous mode.

For wildlife or sports photography, neither camera is ideal - Olympus is a better option when prioritizing reach and manual control, but both will struggle with rapid moving subjects.

Versatility Across Photography Genres

Given these characteristics, how do these cameras fare across different genres?

Portrait Photography

Skin tone reproduction and bokeh quality hinge heavily on sensor size, lens aperture, and lens characteristics. The Olympus’s larger zoom range and faster aperture at the wide end help produce better subject separation and background blur effects, although the small sensor limits the shallow depth-of-field achievable. Face detection autofocus on both cameras aids in locking on to subjects’ eyes, but Olympus’s more capable AF system gives it an edge in accuracy.

Pentax’s slower maximum aperture and lesser zoom stretch make portraits flatter but great for casual use where simplicity is prized.

Landscape Photography

For landscapes, resolution and dynamic range take priority. Both cameras share a 14MP CCD sensor with similar dynamic range limitations, resulting in highlight clipping and shadow noise in challenging scenes. However, Olympus’s wider zoom range can include ultra-wide vistas at 24mm equivalent, which Pentax’s 26mm start slightly hampers. Olympus also benefits from sensor-shift image stabilization, helpful when shooting handheld at slow shutter speeds.

Neither body is weather-sealed, so caution is needed outdoors in adverse conditions.

Wildlife & Sports

Telephoto reach is crucial here, and Olympus’s 36x zoom dwarfs the Pentax’s 5x. Autofocus speed and tracking are moderate on Olympus - with no continuous AF modes or eye tracking, it cannot replace a DSLR or mirrorless system but can get usable results if the subject is relatively stationary.

The Efina’s range and focusing are too modest for serious wildlife or sports work.

Street Photography

Pentax shines in street shooting thanks to its ultra-compact design and discreet operation. Its slim profile means it draws less attention, encouraging candid captures. Olympus, bigger and heavier, is more conspicuous, suitable for deliberate shoots rather than spontaneous street moments.

Both cameras lack silent shutter options, which could be a downside for discretion.

Macro Photography

Olympus allows focusing as close as 5 cm, superior to Pentax’s 20 cm minimum. Combined with sensor-shift stabilization, this supports closer and sharper close-ups, though neither camera is specialized for macros.

Night and Astrophotography

Neither camera excels here. High ISO noise and dynamic range constraints limit long exposure potential, and no specialized astro or bulb modes exist.

Video Capabilities

Both models record at 1280x720 (HD) at 30 fps. Olympus includes sensor-shift stabilization during video, which improves handheld shooting stability noticeably versus the Efina’s digital stabilization - a lower-quality solution often resulting in softer footage.

Neither camera offers microphone or headphone ports, nor do they support 4K video or slow motion. The absence of touchscreen focus or advanced video features restrict creative control for content creators.

Travel Photography

On balance, the Pentax Efina’s extreme portability and ease of use make it a natural travel companion for casual shooters interested in snapshots without bulk. The Olympus, with its broad zoom range and superior ergonomics, is better suited to travelers invested in capturing diverse subjects - from landscapes to wildlife - without swapping lenses.

Build Quality, Weather Resistance, and Reliability

Neither camera features environmental sealing (waterproof, dustproof, shockproof, or freeze-proof). The Olympus has a robust plastic shell with a small thumb rest and decent grip under various conditions. The Pentax Efina, consistent with ultracompacts, employs thinner plastic construction that feels less rugged but very pocketable.

For professional workflows requiring durable gear, neither model qualifies. Both require careful handling in harsh environments.

Battery Life and Storage

Battery life is more explicitly rated on the Pentax Efina (~200 shots), while Olympus offers no official figure but likely performs similarly given comparable batteries. Both cameras use proprietary Lithium-ion batteries (Li-50B for Olympus, D-LI109 for Pentax) that offer respectable endurance for casual day shoots.

Storage-wise, both support SD family cards, including SDHC and SDXC for Olympus, with a single slot each. Olympus also offers internal memory, a minor convenience.

Connectivity and Ports

Olympus features an HDMI output, facilitating direct playback on HD displays - handy for reviewing pictures on a TV. The Pentax lacks an HDMI port, depending solely on USB 2.0 transfers. Neither model supports wireless connectivity such as Wi-Fi, Bluetooth, or NFC, limiting remote control and sharing options popular in modern cameras.

Price and Value Analysis

At release and secondhand in today’s market, Pentax Efina comes at a rock-bottom price (~$10 new in some listings) reflecting a budget ultracompact designed for minimal investment. Olympus SP-810 UZ, priced around $280 at launch, remains a niche superzoom choice, occasionally available used for a hundred dollars or less.

Considering optical capabilities, zoom range, and handling, Olympus delivers clearly better performance and creative flexibility for its price bracket. Pentax’s ultra-low price suits ultra-budget users who desire a capable point-and-shoot without ambitions beyond casual snapshots.
