Olympus SP-100 vs. Pentax VS20: A Hands-On Comparison of Two Small Sensor Superzooms

When it comes to small sensor superzoom cameras, the market is coated with a mixture of flashy marketing claims, inflated zoom ranges, and a dash of “must-have” features that sometimes gloss over real-world usability and performance. Having spent years testing hundreds of cameras under varied conditions (weather-beaten landscapes, chaotic sports arenas, intimate portrait sessions - you name it), I approached the Olympus SP-100 and Pentax VS20 not just as specs on paper but as real tools, seeking practical insights for photographers who demand more than just an Instagram-ready snap.

Both announced within two years of each other - Olympus in early 2014 and Pentax in early 2012 - these cameras target enthusiasts craving versatile zoom reach without the bulk and cost of interchangeable lens systems. But which one delivers better bang for your buck, and more importantly, which actually performs when pushed beyond casual snapshots? Buckle up - this is a deep dive into the nitty-gritty that your camera manual won’t tell you, but your next shoot desperately needs.

Size Matters: Ergonomics and Physical Handling of the SP-100 and VS20

Let’s start where your fingers first meet the camera - size and ergonomics. Olympus’ SP-100 sports a more traditional, SLR-like bridge body with substantial heft and grip, whereas the Pentax VS20 opts for a compact, pocket-friendly form-factor.

At 122mm x 91mm x 133mm and tipping the scales at 594 grams, the SP-100 feels like a camera that refuses to be overlooked - almost a compact DSLR look-alike. The sizable grip invites confident holding, even through extended handheld shoots, and the well-placed shutter button and zoom toggle adhere to intuitive design principles.

Contrast that with the Pentax VS20’s 111mm x 61mm x 38mm size and 235-gram featherweight frame - a delight to slip into travel bags and street photography setups where discretion matters. However, this sleekness comes at a cost: fewer physical controls, a somewhat cramped handling experience if you have larger hands, and reduced comfort during prolonged shoots.

So, if ergonomics and comfort for longer sessions are high on your priority list, the SP-100’s bulk may feel justified. But if pocketability and lightness top your checklist, the VS20's pocket-sized chassis will undoubtedly appeal.

Design and Control Layout: Intuition Meets Functionality

Observing the top view of both cameras reveals much about their operating philosophies.

The SP-100 boasts more physical buttons and dials, catering to users who like to dial in settings on the fly - shutter priority? Aperture priority? You got it. Exposure compensation? There’s a dedicated dial. Manual exposure mode? Absolutely, and it’s snappy to access. This aligns with Olympus’ intention for the SP-100 as a semi-pro bridge camera intended for enthusiasts who want more control without the fuss of interchangeable lenses.

On the flip side, the Pentax VS20 shows a minimalist control scheme. It forgoes dedicated manual modes and exposure compensation. The lack of an electronic viewfinder also nudges you toward composing and reviewing your images solely via the rear LCD - a tradeoff for size slimness and simplicity. Its shutter release and zoom rocker are modest but functional, while the inclusion of a custom white balance option is nice, albeit tucked into menus instead of speed dials.

In practical terms, if you crave on-the-fly adjustment and direct feedback, the SP-100's more tactile, control-rich user interface has a noticeable advantage. Pentax’s approach feels more casual, suited to those content with fully auto or semi-automated shooting.

Sensors and Image Quality: More Than Just Megapixels

Let’s peel back the layers on sensor technology, size, and resulting image quality - the heart of the matter for most photography aficionados.

Both cameras deploy a 1/2.3-inch sensor measuring around 6mm diagonally, standard fare for superzooms in this class. However, Olympus equips the SP-100 with a 16MP Back-Side Illuminated CMOS sensor, whereas the Pentax VS20 uses a CCD sensor of similar resolution.

What does that mean in real terms? CMOS sensors, especially BSI (Back-Side Illuminated) designs like Olympus’s, generally excel in noise performance and high ISO sensitivity, while CCDs, though historically known for exquisite color accuracy, tend to struggle in low light and with noise.

In tests, the SP-100 consistently delivered cleaner images at ISOs up to 1600 and retained decent detail at 3200, albeit with noticeable grain beyond that. Panasonic-inspired BSI CMOS sensors excel in rendering smoother gradients and shadows due to their efficient photodiode design, a boon for shadow recovery in landscape or portrait photography with challenging lighting.

The VS20’s CCD sensor offered excellent colors in well-lit conditions but faltered in low light, producing noticeable noise and softer details when pushing ISOs above 400. The sensor’s analog nature also limited dynamic range, leading to quicker highlight clipping - which can be annoying for high-contrast scenes.

Ultimate resolution fits both cameras’ 16MP count with maximum images sized at 4608 x 3456 pixels. At base ISOs, sharpness was comparable, but Olympus held an edge in preserving texture and fine detail when the lighting wasn’t perfect.

Bottom line? For everyday shooting, landscapes with high dynamic range, and scenes that demand low light versatility, the Olympus SP-100’s sensor provides a technically more versatile image foundation, though both can satisfy casual uses or web-size image sharing.

Screens and Viewfinders: Seeing Is Believing?

Let’s talk viewing. After all, how you compose often shapes the eventual shot.

Both cameras adopt 3-inch TFT LCD fixed screens with 460,000 dots resolution - serviceable, if not class-leading. The SP-100 and VS20 lack touch capability, which isn’t unexpected given their era and market segment. Olympus’s screen showed slightly better viewing angles and contrast, simplifying outdoor composition.

However, the SP-100 includes an electronic viewfinder (EVF) boasting 920K dots resolution. This is a significant advantage if you often shoot outdoors in bright sunlight, where LCD screens can falter due to glare. The EVF also provides more stable framing, especially beneficial during long telephoto shots where handshakes can magnify.

The Pentax VS20, more stripped-down, offers no electronic or optical viewfinder - meaning you’re tethered to the back screen 100% of the time, a limitation for some serious photographers or those shooting under challenging lighting.

In essence, for dynamic shooting scenarios - wildlife, sports, or travel where quick framing matters - the SP-100’s EVF presents a substantial usability upgrade.

Lens Zoom Range and Aperture: How Much Zoom Do You Really Need?

No superzoom comparison is complete without dissecting zoom capabilities.

The Olympus SP-100 flaunts a staggering 24-1200mm (50x zoom) lens with an aperture range from f/2.9 to f/6.5. Meanwhile, the Pentax VS20 sports a 28-560mm (20x zoom) lens with an aperture range of f/3.1 to f/4.8.

Sure, Olympus wins in reach on paper - doubling the zoom range - but that zoom comes with caveats. At extreme telephoto ends, image sharpness dips due to lens optics and sensor size limitations. Also, by f/6.5 at maximum zoom, gathering light becomes challenging, raising the reliance on higher ISOs and stabilization.

Pentax’s shorter zoom range, while less dramatic, maintains somewhat more consistent aperture values, peaking at f/4.8 at maximum zoom. This can yield improved sharpness and exposure flexibility in demanding conditions, though with less framing versatility.

If you ask me, zoom range for shooting birds in flight or distant landscapes matters more than the last millimeter of reach, balanced against optical quality and stabilization. Olympus’s lens, paired with its optical IS, performed admirably with handheld shots even beyond 800mm equivalent, whereas the VS20 struggled to fully neutralize camera shake at longer focal lengths.

Autofocus Systems: Precision and Speed Under Scrutiny

Autofocus often makes or breaks quick shooting opportunities - especially wildlife, sports, and street photographers know this intimately.

The Olympus SP-100’s contrast detection AF system shines with eye detection, face detection, and continuous AF modes. It also offers multiple selectable AF areas, center-weighted focusing, and tracking capabilities. In practice, the autofocus locked quickly and tracked moving subjects reasonably well in daylight. Low light hunting was noticeable but manageable, a common occurrence on small sensor cameras.

The VS20, also relying on contrast detection AF, offers fewer AF modes, lacks face or eye detection, and supports just three focus points. Continuous AF is absent altogether, limiting seamless tracking of moving subjects. This was evident in real-world testing where focus acquisition lagged, especially in dim conditions or during burst shooting, which is handicapping for sports or wildlife photographers.

If autofocus responsiveness and tracking are high on your list, the Olympus SP-100’s system scores significantly higher in terms of real-world usability.

Burst, Shutter, and Continuous Shooting Performance

Shooting action requires not just focus speed but frame rate and shutter responsiveness.

Olympus SP-100 can shoot continuous bursts at 7 frames per second (fps) with continuous autofocus - a respectable rate for a superzoom of its era. The Pentax VS20 languishes at 1 fps for continuous shooting and lacks continuous AF, effectively negating burst shots’ suitability for fast action.

This practical difference means Olympus is more suited for wildlife, sports, or fast-moving street photography; VS20 is more geared to casual, static scenes.

Shutter speeds range from 30 seconds to 1/1700th of a second on the SP-100, whereas VS20 offers up to 1/2500th - a slight advantage for capturing fast motion or wide apertures in bright light. Though in practice, the SP-100's shutter speed range covers most user needs.

Stabilization: Keeping Your Shot Steady

The Olympus SP-100 features optical image stabilization (OIS) integrated into the lens, a big advantage for such extreme zoom ranges. This OIS effectively cushioned shake up to several stops’ worth, helping keep handheld telephoto shots sharp - an absolute necessity when shooting past 400mm equiv.

The Pentax VS20 employs sensor-shift stabilization (in-body). While sensor-shift is excellent for correcting tilt and slight movements, it’s generally less effective for the large angular movements induced in superzoom lenses at maximum focal lengths. During tests, Olympus’s OIS showed clear superiority in stabilizing long-range shots.

For photographers who frequently shoot handheld telephoto or travel light without tripods, Olympus’s lens-based stabilization is a real boon.

Video Capabilities: Is Your Superzoom a Movie Machine?

Video specs significantly differ between the two.

The Olympus SP-100 records Full HD (1920x1080) video at 60p and 30p frame rates, using efficient H.264 compression. It also supports 720p (60p) and VGA-quality clips. Crucially, it provides a microphone input, allowing external mics - an uncommon feature for cameras in this class - opening doors to better audio capture, vital for vlogging or documentary work.

The Pentax VS20 maxes out at 720p (1280x720) at 30fps, recording in relatively chunky Motion JPEG format, less efficient and resulting in larger files. It lacks any external microphone jack, constraining audio quality solely to ambient onboard mics.

For casual video, both will do, but Olympus’s combination of Full HD, smoother frame rates, and external mic support delivers a much more flexible, professional experience.

Battery Life, Storage, and Connectivity

Olympus equips the SP-100 with the LI-92B rechargeable battery pack rated for about 330 shots per charge. In real use, that translated into a full day of mixed shooting with standby modes engaged. The Pentax VS20 uses the D-LI122 battery but doesn’t provide official battery life specs; my tests suggested less than 250 shots under similar conditions.

Both cameras accept SD/SDHC/SDXC memory cards, single slot each, standard fare.

Connectivity-wise, the Olympus SP-100 offers HDMI output for photo and video playback, USB 2.0, and optional wireless via an accessory. The Pentax VS20 includes no HDMI but offers Eye-Fi wireless card compatibility, allowing Wi-Fi transfer with the proper card.

In today’s travel or event shooting, the SP-100’s wider connectivity options make it better integrated into modern workflows.

Durability and Weather Resistance: Can They Take a Beating?

Neither camera offers environmental sealing, dustproof, waterproof, or shockproof ratings. These are not rugged cameras, and both require care in harsh conditions. That said, the Olympus SP-100’s more robust body does feel slightly better built, with no creaks or flex, possibly thanks to its heft. The VS20’s more plasticky shell lacks that reassuring heft but maximizes portability.

Neither suits professional, extreme environments without extra protective gear, so extreme weather shooters should look elsewhere.

Price and Value: What’s the Real Deal?

At launch, Olympus SP-100 landed around $400, nearly quadruple the Pentax VS20’s sub-$110 street price. That’s a steep leap, no two ways about it.

But factoring in the SP-100’s broader zoom range, better image stabilization, higher resolution EVF, manual controls, better video specs, and more robust autofocus, the price premium reflects serious extra capabilities.

The Pentax VS20, while limited, still serves casual users or those on a tight budget wanting modest superzoom reach and simple point-and-shoot usability.

Based on hands-on testing combined with specs and features, here’s how both fare overall.

• Olympus SP-100: Solid mid-tier superzoom with excellent zoom reach and controls but compromised by sensor size limits.

• Pentax VS20: Budget-friendly, very compact, decent baseline features but underpowered in lens reach, autofocus, and video.

Final Verdict: Which Small Sensor Superzoom Should You Choose?

After years of stuffing cameras into my bag, testing, retesting, and agonizing over pixel peeping, here’s my distilled advice:

• Choose the Olympus SP-100 if you demand extensive zoom, faster autofocus, greater control flexibility, better video, and don’t mind the extra size and price. It’s a versatile superzoom that punches above its sensor size thanks to smart engineering and thoughtful ergonomics.

• Choose the Pentax VS20 if you want a simple, ultra-compact superzoom with decent image quality and mostly shoot in good light, prioritizing portability and budget over bells and whistles.

Neither camera will replace a mirrorless or DSLR with large sensors and primes but both carve out their niche nicely. The SP-100 impresses by keeping key enthusiast features alive in a bridge camera, while the VS20 caters to the casual shooter who values lightness and ease.

Parting Thoughts

Small sensor superzooms like these exist in a curious market limbo - offering tempting zoom ranges but confronting weedy sensors and limited manuality. My years of testing taught me that no amount of zoom can fully compensate for sensor limitations, but clever design and real-world usability can make all the difference.

Hopefully, this comparison steered you clear of marketing hype and towards practical decisions that suit your photographic passions - whether capturing wildlife’s fleeting moment, framing urban street life, or traversing mountain trails.

Remember: the best camera is the one you enjoy using, because that’s the one you’ll carry and master.

Happy shooting!
