Olympus SP-100 vs. Pentax H90: A Thorough Comparison for the Discerning Photographer
In the sprawling world of digital cameras, finding the right one for your needs can be a bit like navigating a labyrinth - especially when models like the Olympus Stylus SP-100 and Pentax Optio H90 appear at first glance fairly similar, yet reveal very different strengths on closer inspection. Both were designed with the enthusiast in mind but target quite distinct segments of the market: the Olympus SP-100 is a bridge-style superzoom with a beefy zoom range and flexible controls, whereas the Pentax H90 is a compact point-and-shoot aimed more at casual portability and simplicity.
Having spent years testing cameras under varied real-world conditions, I’m excited to take you through a detailed, side-by-side appraisal of these two contenders. We’ll peer into their specs, hands-on usability, and actual photographic performance across multiple genres - from portraits and landscapes to wildlife, street, and more. Throughout, I’ll highlight which camera suits which shooter, all based on my firsthand experience with their quirks and strengths.
Let’s take a closer look.
Size, Build, and Ergonomics: First Impressions Matter
The very first thing you’ll notice about these two cameras is their diverging philosophies on design and handling.
The Olympus SP-100, with its SLR-like bridge body, feels substantial in your hands. Weighing in at nearly 600 grams and measuring roughly 122 x 91 x 133 mm, it conveys a commanding presence. It reminds me instantly of a DSLR in shape and grip comfort, which is a real advantage for photographers who want that confident hold combined with a massive zoom range.
By contrast, the Pentax H90 is a diminutive compact camera, featherlight at just 153 grams and slim - about 101 x 65 x 28 mm. It slips effortlessly into a pocket or small bag, making it an ideal grab-and-go choice for casual users or travelers wary of bulky gear.
Take a look at the physical size comparison below to really appreciate the difference in scale:
In testing, the Olympus’s larger grip facilitated steadier handholding at telephoto lengths, especially when zoomed all the way to 1200mm equivalent. The Pentax, meanwhile, won points for portability but felt a bit fiddly during longer sessions or in challenging lighting, with smaller buttons that were sometimes difficult to manipulate quickly.
Build quality on both is typical for their classes: Mainly polycarbonate construction without weather sealing. Neither is engineered for harsh environmental exposures, so if you’re outdoors in rain or dust, careful protective measures are required.
Top-Down: Controls and User Interface
Controls are the connective tissue between you and your camera - and here the two models take very different approaches.
The Olympus SP-100 embraces a more advanced control scheme suited to enthusiasts who want manual exposure options, different shooting modes, and tactile dials. This top control layout lets you quickly adjust shutter speed, aperture, and exposure compensation without peering through menus constantly.
The Pentax H90, aimed at simplicity, offers more limited manual controls - no aperture or shutter priority modes, and no exposure compensation. It mostly relies on automatic modes and a slow single-shot rate, suiting users who prefer point-and-shoot straightforwardness.
The contrasts are nicely visible in this top view comparison:
From my experience testing both cameras, the SP-100’s dedicated buttons and control wheels vastly improved workflow efficiency during complex shoots like landscapes and wildlife. For street or family snapshots, though, the Pentax’s minimalist button layout is easier to navigate, especially for newcomers.
Under the Hood: Sensor Technology and Image Quality
This is where things start to diverge technically and the real differences begin to affect image outcomes.
Both cameras use the popular 1/2.3-inch sensor size, measuring approximately 6.17 x 4.55 mm, common in compact and bridge cameras. However, the Olympus SP-100 employs a more modern BSI-CMOS sensor with a resolution of 16 megapixels, while the Pentax H90 relies on an older CCD sensor delivering 12 megapixels.
The BSI-CMOS design in the Olympus allows for better light gathering efficiency and typically improved noise performance in dim lighting. Moreover, Olympus includes optical image stabilization - a critical factor, especially given the SP-100’s extremely long 50x zoom lens.
Sensor comparisons can get very technical, so here’s an image to help put it into perspective:
Having shot side by side under identical conditions, the Olympus showed clearer, sharper details at base ISO settings, and less chromatic aberration at telephoto extremes, which you can also see in this sample gallery:
The Pentax images often felt softer and less vibrant out of the box, and the sensor’s CCD technology was more prone to noise creeping in at higher ISOs above 400. The Olympus excels in dynamic range too, rendering shadow detail with more finesse, an advantage for landscape and night photography.
While neither camera supports RAW output, this is a notable limitation for enthusiasts interested in post-processing flexibility.
The View: LCD Screens and Electronic Viewfinders
The SP-100 offers a 3-inch 460k-dot fixed TFT LCD, which is bright and fairly crisp, providing a comfortable framing and reviewing experience. It complements the camera’s electronic viewfinder (EVF) with a resolution of 920k dots - a rarity at this price point and vital when shooting in bright daylight.
The Pentax H90 has a slightly smaller 2.7-inch LCD with 230k dots, and no EVF. This meant I had to rely solely on the rear LCD, which can be tricky in harsh sun - a common frustration in travel or street shooting conditions.
Here’s a comparative look at the rear screens:
In my practical use, the Olympus’s EVF and richer LCD resolution made composing in varied lighting conditions simpler and less fatiguing - a huge plus for extended shooting sessions.
Autofocus System and Shooting Speed: Capturing Decisive Moments
Autofocus (AF) performance can make or break your photography, especially in genres demanding speed and accuracy.
The Olympus SP-100 employs a contrast-detection AF system complemented by face detection, continuous AF, and center and multi-area AF modes. Its AF tracking was surprisingly responsive for a bridge camera, capable of maintaining focus on moving subjects during bursts at 7 frames per second.
The Pentax, using contrast detection only, lacks continuous AF and face detection, relying primarily on a 9-point AF system with single AF mode only, and a slow single shot rate of just 1 fps.
This means the Pentax is best reserved for static subjects or casual snapshots, where a slower AF response isn’t a deal-breaker.
I put both to the test tracking wildlife and sports action. The Olympus confidently nailed sharp shots of fleeting bird flights and children at play, while the Pentax struggled to lock focus quickly and track moving subjects consistently.
Zoom and Lens Reach: Exploring Focal Lengths
When it comes to zoom, the difference couldn’t be starker.
- Olympus SP-100: 24-1200 mm equivalent (50x zoom), f/2.9-6.5
- Pentax H90: 28-140 mm equivalent (5x zoom), f/3.5-5.9
The Olympus’s ultra-telephoto reach is exceptional for wildlife and distant landscapes - you can really explore faraway subjects without lugging heavy lenses. The fast aperture of f/2.9 at wide angle also helps in low light.
Pentax’s shorter zoom is more general-purpose and somewhat limiting for wildlife or sports but suits travel and street photography well where portability and convenience matter.
Such a wide zoom must have solid stabilization - the Olympus has optical IS built into its lens assembly; the Pentax uses sensor-shift stabilization, which is decent but not as effective at long focal lengths.
Battery Life, Storage, and Connectivity
The Olympus SP-100 uses a rechargeable LI-92B battery pack, rated at about 330 shots per charge under standardized CIPA testing. That’s a respectable endurance for a bridge camera, allowing extended outings without spares.
The Pentax H90 uses a smaller D-LI68 battery (standard AAA/ proprietary style) but official endurance figures aren’t available. In everyday use, I found it sufficient for casual day trips but less forgiving during heavy shooting sessions.
Both accept standard SD/SDHC/SDXC cards with one slot. USB 2.0 connectivity is supported by both, with Olympus adding a micro-HDMI port for live view on external monitors or quick playback.
Wireless capabilities differ slightly: Olympus offers optional wireless adapters; the Pentax has built-in Eye-Fi support for wireless image transfer but lacks Bluetooth or NFC for quick pairing.
Video Capabilities: Beyond Stills
Video quality is an often overlooked factor today, even in small sensor cameras.
-
Olympus SP-100 records Full HD 1080p at 60 fps using the efficient H.264 codec; also supports 720p and VGA resolutions. It includes a microphone input jack for better audio recording - a thoughtful addition often missing at this price.
-
Pentax H90 maxes out at 720p 30 fps and uses the older Motion JPEG format, which consumes larger file sizes and offers less compression efficiency.
For videographers on a budget, the Olympus is clearly the more capable choice, both in resolution and audio flexibility.
Performance Ratings and Genre Suitability
