Olympus SP-800 UZ vs. Pentax K-1 Mark II: A Deep Dive into Two Very Different Cameras

Over my 15+ years immersed in the world of photography equipment testing, few comparisons are as instructive - and frankly as fun - as pitting a compact superzoom like the Olympus SP-800 UZ against a full-frame advanced DSLR like the Pentax K-1 Mark II. They live at opposite ends of the camera spectrum: one, a pocketable zoom-lover’s tool; the other, a professional-grade imaging machine built to conquer the demands of serious photographers.

In this article, I’ll share my firsthand experience evaluating these two bodies across various shooting scenarios, dissecting their technical capabilities, ergonomic realities, and real-world performance. Whether you’re a casual snapshooter or a working pro hunting for high fidelity, this thorough comparison will shed light on which camera could suit your style and budget best.

Feeling the Cameras: Size, Weight, and Handling

One of the first and most obvious differences between these cameras is their size and ergonomics. The Olympus SP-800 UZ is a compact superzoom with a fixed lens that fits comfortably in a roomy jacket pocket or small bag. In contrast, the Pentax K-1 Mark II is a robust mid-size DSLR - larger and heavier, but designed for a firm, secure grip and intuitive access to controls.

From my extensive hands-on testing sessions, I found the SP-800 UZ pleasant for travel and street shooting, since it doesn’t draw much attention and slips easily into my hand. That said, the Pentax’s heft and sturdier grip feel reassuring for long outdoor shoots, especially when paired with pro-grade lenses. I often found myself appreciating the K-1 II’s old-school tactile dials and buttons, which made exposure adjustments quicker without taking my eye off the subject.

One caveat on portability: The K-1 II’s weather sealing adds bulk but protects it in tough conditions, an advantage many professionals appreciate in unpredictable environments.

A Window to the World: Viewing and Controls

The user interface and viewing experience constitute a major part of daily use. Both cameras offer live view, but the Olympus has a fixed 3” LCD screen with 230k-dot resolution - serviceable but not very detailed. Meanwhile, the Pentax K-1 II features a fully articulated 3.2” screen with over 1 million dots, making image composition and review a significantly richer experience.

The Pentax’s optical pentaprism viewfinder delivers 100% coverage and a crisp, bright image with 0.7x magnification, which I found essential for precision framing and manual focusing, especially in bright daylight.

In contrast, the Olympus SP-800 UZ lacks any form of viewfinder, which may be challenging outdoors under strong sunlight - I often used the rear screen but wished for an eye-level option in such situations.

When it comes to controls, the SP-800 UZ is simplified: it lacks manual exposure modes, with no shutter or aperture priority, focusing mainly on automatics and scene presets. The Pentax K-1 II, however, is richly featured: full manual controls, customizable buttons, and quick access to exposure compensation make it a dream for seasoned shooters who demand fluid workflow and creative control.

Under the Hood: Sensor Performance and Image Quality

This is where the two cameras most starkly differ. The Olympus SP-800 UZ has a 1/2.3" 14MP CCD sensor - typical of compact superzooms from its era - while the Pentax K-1 II boasts a 36MP full-frame CMOS sensor without an anti-aliasing filter.

The larger sensor surface area of the Pentax (about 861 mm²) compared to the Olympus’s tiny 28 mm² sensor dramatically influences image quality. In my tests, the Pentax delivered superior resolution, dynamic range, and low noise - results you’d expect given the sensor size and technology.

While the SP-800 UZ suffices for casual snapshots with decent detail in good lighting, it struggles in low light or high contrast scenes, with visible noise creeping in past ISO 400 and a limited dynamic range that clips highlights easily. The 30x optical zoom lens offers incredible framing flexibility but compromises sharpness at maximum zoom.

The Pentax’s high-resolution files retain fine details impressively, enabling large prints and extensive cropping without degradation. Moreover, it offers an extraordinary native ISO range from 100 to a whopping 819,200 (albeit the highest values are more experimental), which I found usable up to about ISO 12,800 for clean results in very challenging lighting.

In terms of color depth and tonal subtlety, the K-1 II’s sensor pushes a richer palette, benefiting portraits and landscapes especially.

Focusing on Autofocus: Speed and Precision

Autofocus speed and accuracy can make or break shots, particularly in wildlife and sports photography. The Olympus SP-800 UZ employs a contrast-detection system with 143 focus points, offering decent lock-on tracking. However, it lacks phase detection and continuous autofocus modes, meaning it takes longer to achieve focus and struggles with fast-moving subjects.

By contrast, the Pentax K-1 II features a hybrid phase and contrast detection system with 33 autofocus points (including 25 cross-type sensors). This system excels in acquiring and maintaining focus on a variety of subjects including human faces and moving animals, thanks to features like face detection and multiple AF modes.

During my field trials photographing birds in flight, the K-1 II tracked swiftly and accurately with its continuous AF mode, while the Olympus’s single AF mode often lagged or hunted, missing fleeting moments.

Zoom, Macro, and Creative Potential

One of the SP-800 UZ’s biggest draws is its massive 28-840mm (35mm equivalent) zoom, allowing for versatility uncommon in compact cameras. Close-up, it focuses down to 1 cm - a boon for macro enthusiasts wanting convenience without changing lenses.

The Olympus’s built-in 5-axis sensor-shift image stabilization aids in reducing motion blur at long focal lengths or slower shutter speeds, invaluable for handholding its extreme zoom.

The Pentax K-1 II, being a DSLR, relies on interchangeable lenses. My preferred macro lens with it delivered exquisite detail and shallow depth of field for close-up work, indicating far superior creative control over magnification and bokeh quality compared to the SP-800 UZ’s fixed lens.

Weather Sealing and Durability – Ready for Adventure?

If you photograph outdoors frequently, environmental sealing is vital. The Pentax K-1 II is weather sealed against dust and moisture, a feature I personally value highly, enabling worry-free shooting in light rain or dusty environments.

The Olympus SP-800 UZ, however, is not weather-sealed and lacks ruggedness protections. It’s best considered a gentle-use travel companion rather than a beast-of-burden.

Video Capabilities: Modest vs. Modern

Both cameras record video, but the K-1 II stands far ahead in quality and flexibility.

The Olympus SP-800 UZ supports 720p HD video at 30fps with H.264 compression, which was acceptable for casual video in 2010 but now feels dated, offering no external microphone input or advanced features.

The Pentax K-1 II records full HD 1080p up to 60i/50i and 30p/25p, including an external microphone jack and headphone monitor port - essential for serious videographers aiming for quality sound capture.

Neither supports 4K, but the K-1 II’s higher bitrate video and articulating screen make it better suited for mixed photo/video workflows.

Battery Life and Storage: Convenience Counts

The K-1 II dramatically outperforms the Olympus in battery endurance. With a rated 670 shots per charge using its powerful D-LI90 battery, I found it reliable for day-long shooting sessions.

The Olympus’s battery life isn’t officially specified, but in practice, its smaller Li-50B battery yields significantly shorter shooting intervals - expect recharging or carry spares on extended outings.

In terms of storage, the K-1 II uses dual SD card slots (supporting high speed UHS-I cards), facilitating overflow shooting and instant backups - a pro-level feature missing in the single SD/SDHC slot of the Olympus.

Connectivity and Extras

Neither camera supports Bluetooth or Wi-Fi, which limits immediate image sharing or remote control via smartphones - reflecting their design eras and target users.

However, the Pentax includes built-in GPS, enabling geotagging - a useful feature when logging shoots on location, especially in travel or nature photography.

Image Samples: Putting Pixels To The Test

To illustrate these capabilities, I have shot a series of sample images from both cameras in natural light, indoors, with fast subjects, and macro scenes. The difference in resolution, color fidelity, and dynamic range is striking.
