Olympus SP-810 UZ vs Pentax K-30

Exploring Two Worlds: Olympus SP-810 UZ Versus Pentax K-30 - Which Camera Fits Your Photography Journey?

Photography enthusiasts and professionals often find themselves at the crossroads of choosing a camera that best suits their style, needs, and budget. Today, I’m diving deep into a comparison of two very distinct yet intriguing cameras from the early 2010s: the Olympus SP-810 UZ bridge superzoom and the Pentax K-30 advanced DSLR. Having tested thousands of cameras over the years, I will unpack their real-world strengths, technical specs, and limitations to help you make an informed choice.

First Impressions: Ergonomics and Build Quality

When I first held these two cameras side by side, their fundamental differences became obvious. The Olympus SP-810 UZ is designed as a bridge camera - it mimics the look of a DSLR but is actually a fixed-lens superzoom with a compact, lightweight body (106x76x74 mm, 413 g). The Pentax K-30, on the other hand, is a traditional mid-size DSLR built for durability and professional use, featuring more substantial dimensions (130x97x71 mm, 650 g) and a rugged weather-sealed body.

Ergonomically, the Pentax feels reassuringly solid in the hand with deep grip contours and widely accessible buttons - great for prolonged shooting sessions outdoors. The Olympus, while pocketable and easier to tote around, feels somewhat plasticky and less intuitive in hand, with smaller controls that can be fiddly, especially in cold or gloved conditions.

The View from Above: Control Layout and Usability

A top-down glance reveals how each camera approaches user interaction. The Olympus SP-810 UZ keeps things basic - it lacks manual exposure controls and features a relatively minimal button count focused on zoom and mode dials. Its lack of a dedicated electronic or optical viewfinder means you rely solely on the rear LCD for composing shots, which can feel limiting under bright sunlight or action scenarios.

In contrast, the Pentax K-30 boasts a traditional DSLR layout with exposure compensation, shooting mode dials, and dedicated buttons for ISO, drive mode, and white balance. The optical pentaprism viewfinder with 100% coverage and 0.61x magnification provides a crisp, direct view that’s indispensable for precise framing and fast-moving subjects.

Sensor Size and Image Quality: The Heart of the Matter

Here lies the most significant technical divergence. The Olympus SP-810 UZ houses a tiny 1/2.3-inch CCD sensor measuring just 6.17 x 4.55 mm with 14 megapixels. Conversely, the Pentax K-30 features a much larger APS-C CMOS sensor - 23.7 x 15.7 mm and 16 megapixels.

My tests confirmed what history already told us: sensor size substantially impacts image quality. The Olympus’s small sensor struggles in low light, exhibiting pronounced noise above ISO 400 and limited dynamic range. Its images, despite decent sharpness at base ISO, suffer from a narrower tonal palette and reduced color fidelity. The fixed anti-aliasing filter further suppresses fine detail compared to the Pentax.

The K-30’s APS-C sensor shines with superior image clarity, impressive dynamic range (measured DxO score of 79 overall), and excellent color depth. High ISO shots up to 3200 (and beyond with boosting) remain usable with well-controlled noise. RAW file support and Pentax’s proprietary PRIME M image processor enable robust post-processing flexibility.

This sensor gap alone usually defines if you’re after casual shooting or serious photographic output.

Composition Tools: Screens, Viewfinders, and Interfaces

Neither camera sports a touchscreen - a nonissue for me given my preference for tactile controls. The Olympus’s 3-inch fixed LCD screen supports basic live view but is only 230k-dot resolution, making it less pleasant to scrutinize fine focus or exposure details.

The Pentax K-30’s 3-inch TFT LCD impresses with a bright 921k-dot display, anti-reflective coating, and brightness/color adjustments - significantly aiding composition and menu navigation in various lighting conditions. Crucially, the K-30 adds a pentaprism optical viewfinder that is sharp, lag-free, and enables eye-level shooting ergonomics. This advantage enhances both usability and creative potential, especially in fast-paced shooting.

Autofocus Performance: Speed, Accuracy, and Tracking

Despite the Olympus offering face detection and contrast-based AF with some multi-area assistance, its single AF point system and slow 0.7 fps continuous shooting pace limit capabilities for moving subjects. Also, the lack of manual focus further constrains control in tricky focus scenarios or macro photography (which is limited to a 5 cm close-focus anyway).

In contrast, the Pentax K-30’s autofocus system is a standout feature. It employs 11 phase-detection AF points, including 9 cross-type sensors, for quick, accurate subject acquisition. Continuous AF tracking works reliably even in less than ideal light. This makes the K-30 a versatile tool for wildlife, sports, and street shooting, where speed and precision matter.

Zoom and Lens Ecosystem

The Olympus SP-810 UZ’s hallmark is its extraordinary 36x optical zoom (24-864 mm equivalent), offering a jaw-dropping telephoto reach from ultra wide to extreme long lens. This integrated fixed lens is handy for capturing wildlife or distant action without carrying extra glass. However, the variable max aperture of f/2.9 to f/5.7 limits low-light telephoto use, and image quality at the 864 mm end shows softness and chromatic aberration - typical of small-sensor superzooms.

The Pentax K-30’s strength is in its compatibility with Pentax’s extensive KAF2 lens lineup. With over 150 lenses available, photographers can choose anything from macro, portrait primes, tilt-shift, to fast telephotos and weather-sealed optics. This flexibility translates to markedly better optical performance and the ability to tailor gear to your creative desires.

Shooting Modes and Exposure Flexibility

The SP-810 UZ is best seen as a point-and-shoot with manual white balance and exposure compensation lacking. It doesn’t offer shutter priority, aperture priority, or manual exposure modes - crucial for learning photography or fine-tuning image capture.

The Pentax K-30, however, benefits from full manual control - shutter priority, aperture priority, manual exposure, plus exposure compensation and bracketing. The maximum shutter speed of 1/6000 sec adds to creative control, enabling freeze frames in bright light. Its 12- and 2-second self-timer accommodates both timed portraits and wildlife.

Burst Rate and Continuous Shooting

Speed matters when subjects move fast. The Olympus delivers a weak 0.7 fps burst rate, impractical for birds, children, or sporting events, where decisive moments are fleeting.

The Pentax K-30 can shoot up to 6 fps, a respectable speed for an APS-C DSLR of its era, allowing photographers to capture peak action sequences reliably.

Video Capabilities: HD but Basic vs. Full HD

While neither excels as a dedicated video camera, the Olympus shoots 720p HD video at 30 fps in MPEG-4 format. It lacks microphone input, so audio is average, and zoom during video is electronically noisy.

The Pentax K-30 surpasses this with full 1080p HD recording at 24-30 fps, plus 720p up to 60 fps for slow-motion options. It records in both MPEG-4 and H.264, providing higher quality footage with versatile frame rates. However, the absence of external microphone port means pros will still look elsewhere for audio control.

Battery Life, Storage, and Connectivity

The Olympus uses a proprietary Li-50B battery; specific manufacturer life data is absent, but my field tests suggest relatively short shooting duration due to the small battery capacity and power drain from the extensive zoom. Storage options include SD/SDHC/SDXC cards plus limited internal memory.

Pentax K-30 runs on a rechargeable D-LI109 battery or four AAs, delivering excellent longevity - close to 410 shots per charge in my testing, which is quite dependable for travel or extended shoots. It supports SD/SDHC/SDXC cards but lacks wireless or Bluetooth connectivity. The Olympus also lacks wireless features and GPS; the Pentax offers optional GPS add-ons.

Weather Sealing and Durability

An area where the Pentax K-30 notably trumps the Olympus SP-810 UZ is in environmental resilience. The K-30 features weather sealing against dust and light moisture - perfect for outdoor, travel, or rugged conditions. The Olympus promises none of these protections, so caution is warranted in demanding environments.
