At first glance, these cameras occupy nearly opposite ends of the photographic spectrum. Our mission is to break down what that means for you.

Understanding the Physical and Ergonomic Differences

Handling and Size

The Olympus SP-810 UZ is compact and lightweight, weighing just 413 grams with dimensions roughly 106x76x74 mm. Its SLR-like appearance belies its bridge camera status - meaning it has a fixed lens and limited physical controls.

The Pentax K-1, on the other hand, is a full-fledged DSLR weighing 1010 grams with a more robust, mid-sized body measuring 137x110x86 mm. Its weather-sealed build is designed for professional use in a variety of environments.

Implication: If portability and ease of transport are paramount - say, for casual travel or everyday use - the Olympus has clear advantages. If you prioritize ruggedness and extended handling comfort with access to physical controls, the Pentax is your go-to.

Control Layout and Interface

Expect a very different user experience in terms of controls. The Olympus SP-810 offers minimal manual controls, aimed at point-and-shoot ease. Manual focus and exposure modes are absent, limiting creative control. The 3” fixed LCD with 230k resolution offers basic compositional assistance but is less detailed.

The Pentax K-1 boasts a fully articulated 3.2” LCD with 1037k resolution, a useful top LCD panel, and a dense layout of buttons and dials tailored for direct manual control over aperture, shutter speed (up to 1/8000 sec), ISO, and exposure compensation.

Expert Tip: In our testing, the Pentax’s articulating screen and tactile buttons significantly speed up workflow in the field, while the Olympus feels geared towards simplicity.

Sensor Performance and Image Quality: Where the Rubber Meets the Road

Sensor Specifications and Raw Power

The Olympus features a 1/2.3” CCD sensor with 14 megapixels, delivering images with maximum resolution of 4288x3216 pixels. However, this diminutive sensor size and CCD technology inherently limit dynamic range, low-light performance, and detail retention, especially above ISO 400.

The Pentax K-1 sports a 36-megapixel full-frame CMOS sensor (35.9x24 mm), yielding 7360x4912 pixel images. Developed without an anti-aliasing filter, it maximizes sharpness and detail. This sensor boasts exceptional dynamic range (14.6 stops) and impressive high ISO usability (native up to 204,800 extended).

This difference in sensor size and technology is critical. Larger sensors improve noise performance, tonal gradations, and bokeh quality. The Olympus excels in daylight, compactness, and superzoom leveraging, but won't match the Pentax’s output in professional-level image detail.

Color Depth and Dynamic Range

While DXOMark hasn’t tested the Olympus model, the consensus for its class suggests limited color depth and highlight recovery. The Pentax K-1 scored an overall rating of 96, with 25.4 bits color depth and 14.6 stops dynamic range, putting it among the top full-frame cameras for image quality.

Practical takeaway: For demanding portrait, landscape, or professional reproduction uses, the K-1’s sensor delivers nuanced skin tones and shadow recovery. For snapshots and travel zoom, the Olympus sensor is acceptable but falls short of professional standards.

Autofocus Capabilities and Speed: Catching the Moment

The Olympus SP-810 UZ employs contrast-detection autofocus with face detection but no phase-detection. It has continuous AF tracking mechanisms but slow and less accurate overall - typical for the superzoom bridge cameras of its generation.

The Pentax K-1 features a sophisticated hybrid AF system with 33 focus points (25 cross-type), phase-detection for speed and accuracy, and reliable subject tracking. It can focus in continuous and single modes, with options for selective point AF, center weighting, and face detection.

Continuous Shooting

• Olympus tops at 0.7 fps - too slow for sports or fast action.
• Pentax reaches 4.4 fps - enough for moderate sports and wildlife work, though not extremely fast compared to specialized cameras.

Performance in Major Photography Genres

Portrait Photography

Portraits require accurate skin tones, smooth bokeh, and reliable eye detection for sharp focus.

• Olympus: The small sensor and low megapixel count make medium-quality portraits. Bokeh is limited, given the narrow aperture at long zoom ends. Face detection helps but lacks eye AF precision.

• Pentax: The big full-frame sensor and 36 MP resolution deliver superb detail and shallow depth of field for those beautiful creamy backgrounds. The AF system is accurate enough to nail eye focus in various light.

Recommendation: For portraits, the K-1 is significantly superior and suited to professional headshots and creative portraits. The SP-810 UZ is more casual or experimental.

Landscape Photography

Landscapes benefit from high resolution, dynamic range, and weather sealing.

• Olympus covers a decent focal range but low resolution and limited dynamic range constrain output. The fixed lens and lack of weather sealing reduce utility in demanding outdoor conditions.

• Pentax excels with a large sensor, outstanding resolution, and weatherproofing. Its pixel shift technology enhances color accuracy and detail beyond the sensor’s base performance.

Wildlife Photography

Wildlife demands fast shutter speeds, rapid autofocus, and long telephoto reach.

• Olympus’s 36× zoom lens is tempting for reach but suffers from slow AF and low burst rate.

• Pentax requires pairing with telephoto lenses, but offers quick AF, superior burst rate, and better image quality - critical for cropping flexibility.

Sports Photography

Fast autofocus, high frame rate, and low-light performance are vital.

• Olympus’s low burst speed and slow AF limit effectiveness.

• Pentax delivers respectable 4.4 fps, robust AF with tracking, and higher ISO range to capture indoor/low-light action.
