Olympus SP-800 UZ vs Pentax Optio E70: A Hands-On Comparison for the Practical Photographer

Choosing the right compact camera can feel like trying to pick your favorite ice cream flavor - there are so many options, and each has its quirks and perks. Today, we’re diving into a true compact clash: the Olympus SP-800 UZ, a superzoom powerhouse from 2010, facing off against the Pentax Optio E70, a more modest compact shooter from a year earlier. Both hail from the era when point-and-shoots were still the go-to daily cameras before smartphones took over, and they both target users who want something pocketable, affordable, but with decent image-making chops.

Having personally logged hundreds of hours testing cameras in this size and class, I’m excited to walk you through this matchup. We’ll examine virtually every angle - from sensor specs to autofocus finesse, ergonomics to usability in actual shooting scenarios - all sprinkled with hard-earned insights. If you’re pondering which of these vintage gems deserves a spot in your collection or just want to learn about how these cameras stack up beyond spec sheets, you’re in the right place.

Let’s kick off with the basics of their physical presence, because size - and how it feels in your hands - can make or break your photographic experience.

Size and Handling: When Ergonomics Meet Portability

The Olympus SP-800 UZ is what I’d call [...] a compact in the truest “travel zoom” spirit - it crams a lot of reach (28–840mm equivalent!) into a body that, while chunkier than tiny point-and-shoots, still routes into the realm of carry-on-friendly gear. The Pentax Optio E70 is smaller and lighter, designed for effortless pocket carry, but pays for that with fewer extras and a shorter telephoto reach.

Comparing their body dimensions side by side reveals how each balances heft and portability:

The Olympus SP-800 UZ commands more presence, offering substantial grip real estate and control space. The Pentax Optio E70 favors ultra-compact design but feels less substantial in hand.

To put numbers on it: Olympus weighs in at about 455 grams and measures 110 x 90 x 91 mm, while the Pentax is feather-light - a mere 175 grams and a sleek 94 x 61 x 26 mm.

Which do I prefer in real-world use? For a day hiking or travel shoot, I’m happy to carry the Olympus’s extra weight for the zoom versatility and control comfort. The grip invites you to shoot confidently without awkward slipping, and that 3-inch screen (versus a 2.4-inch on the Pentax) makes framing easier. However, if your priority is truly pocketable stealth - say street shooting or casual snapshots - the Pentax cannot be beaten for grab-and-go convenience.

The weight difference also translates into balance: the Olympus feels sturdier but can tire your wrist after prolonged use, whereas the Pentax’s light weight makes it a better everyday companion for very casual shooters.

Moving to the control surface - because how a camera handles fundamentally shapes your experience.

Control Layout and Top-View Design: Intuitive or Overwhelming?

Neither camera goes full-on manual mode, so you’re dealing mainly with point-and-shoot simplicity here. That said, button placement and labeling can speed - or slow - your workflow, especially as autofocus or shooting conditions challenge your reflexes.

Let’s check their control layouts from above:

The Olympus offers dedicated zoom lever and mode dial, while the Pentax keeps things minimalist with fewer physical controls.

Olympus SP-800 UZ features a traditional mode dial (though limited to automatic modes), a zoom lever encircling the shutter button, and an array of buttons for menu, playback, and flash options. The grip’s size lends itself to precise control - something that matters when “zoom creep” real estate grows with your lens reach.

By contrast, the Pentax E70 simplifies with minimal buttons and no dedicated zoom lever - you control zoom via a rocker button that feels less precise. Its ultra-compact design trades tactile control for portability. The smaller screen and sluggish interface make menu navigation feel more clunky on the Pentax, a constraint likely to frustrate those who want quick on-the-fly settings adjustments.

So if you’re the type who demands speedy access to creative control (or even quick flash toggling for portraits or street situations), the Olympus setup feels more intuitive and less likely to slow you down mid-shoot.

Now, let’s dig deeper into the heart of image quality - sensor specs and real-world performance.

Sensor Technology and Image Quality: Beyond Megapixels

On paper, the Olympus comes with a 14-megapixel 1/2.3" CCD sensor, slightly bumping the Pentax’s 10-megapixel sensor of the same size. Both sensors use CCD technology, which was standard for compact cameras at that time but now considered a bit slow and less flexible compared to CMOS tech. Sensor size and resolution balance significantly impact noise performance, dynamic range, and detail rendition.

To better visualize their sensor specs:

Both cameras employ 1/2.3" CCD sensors with similar areas (~28 mm²). Olympus edges out slightly in resolution, which translates to higher maximum image sizes.

The Olympus’s sensor resolution maxes out at 4288 x 3216 pixels, while the Pentax reaches 3648 x 2736 pixels. So, the Olympus can potentially extract finer detail - assuming lens quality and image processing keep up.

But resolution isn’t everything. The Pentax impressively maxes out ISO sensitivity at 6400 native, versus the Olympus’s 3200. But remember, CCDs generally produce noisier images at high ISO values than modern CMOS sensors. My experience shooting both at ISO 800 and above confirms that neither is stellar for low-light, but the Pentax’s higher max ISO is more marketing than practical - images beyond ISO 400 show heavy noise and softness.

Color depth and dynamic range aren’t formally measured for these models by DxOMark, but visually the Olympus tends to produce more balanced exposure with better control over highlights and shadows. The Pentax sometimes struggles with highlight clipping in bright scenes, likely due to older image processing.

Here’s a quick look at sample images taken under identical lighting conditions from both cameras, resized for web but unretouched:

If you’re prioritizing image quality for landscapes or portraits, Olympus leads here - especially with its longer zoom and sharper detail rendition. Pentax’s images often feel fuzzier, dialing down the “pop” and precision you might desire.

Screen and Viewfinder: Visualizing Your Shots in Real-Time

Neither camera sports an electronic viewfinder, leaving the live LCD screens as the primary composition tool. Screen size, resolution, and angle can make or break your day of shooting.

The Olympus features a 3-inch fixed LCD with 230k-dot resolution, while the Pentax opts for a smaller 2.4-inch screen offering only 112k dots.

The Olympus SP-800 UZ’s display delivers a clearer, more vibrant image, easing framing and review. The Pentax’s screen feels cramped and dimmer, challenging outdoor use.

From personal field experience, the Olympus’s screen handles bright daylight reflections better and feels responsive navigating menus or preview images. The Pentax’s screen is often frustratingly dark in bright conditions, making it harder to confirm focus and composition.

If you rely heavily on LCD feedback - and are shooting in varied lighting - this is a meaningful practical advantage for the Olympus.

Autofocus and Handling Performance: Hunting or Pinpoint Precision?

Autofocus is where real-world shooting speed, accuracy, and reliability are tested. Both cameras rely on contrast detection - standard fare for compact cameras - but their implementation differs.

The Olympus boasts 143 focus points (multi-area AF), tracking capability, and continuous AF modes, while the Pentax only offers 9 focus points with no tracking, and only single AF.

Confession: In my own testing shooting moving subjects (dogs, kids, cyclists), the Olympus autofocus led by a clear margin. Its 10 fps continuous shooting mode (surprisingly fast for a point-and-shoot from 2010) combined with AF tracking makes sports or wildlife snapshots possible, if not professional-grade.

The Pentax’s AF is reliable when subjects stay still but falters with quick motion - frustrating for indoor kids’ parties or wildlife.

If you lean toward wildlife, sports, or street photography with fast-moving subjects, Olympus’s autofocus and burst rate capabilities offer clear advantages.

Lens Versatility: Zoom Reach vs Compact Convenience

Magnification and aperture range shape the creative reach of your camera. The Olympus SP-800 UZ offers an impressive 30× zoom, equivalent to a 28-840 mm lens, starting fast at f/2.8 aperture on the wide end and slowing to f/5.6 at telephoto range.

The Pentax Optio E70, predictably, offers a more pedestrian 3× zoom - 35-105 mm equivalent - with smaller maximum apertures of f/3.1 to f/5.9.

This is the classic superzoom vs simple compact tradeoff: Olympus lets you shoot wide-angle landscapes one moment, then zoom into distant wildlife without swapping gear. The Pentax forces you to crop in post or get closer physically.

Olympus’s wide starting aperture and long zoom open up more shooting scenarios - from portraits with some background separation at 28 mm to tight telephoto shots. However, optical quality at full zoom can degrade - a common superzoom quirk - but Olympus’s lens optics generally outperform others in this range.

Pentax’s smaller zoom range limits compositional options but can produce less optical distortion and better overall sharpness within its limited range, useful for casual snapshots or portraits in good light.

Battery Life and Storage: How Long Will They Last in the Field?

Battery endurance is often underestimated in compact cameras but hugely impacts using them on trips or during events.

The Olympus SP-800 UZ employs a proprietary Li-50B lithium-ion rechargeable battery, providing a reasonable number of shots per charge (manufacturer claims around 280 shots; real-world use sees 200–250 shots), which is decent for a camera with power-hungry superzoom.

On the flip side, the Pentax Optio E70 runs on two AA batteries - a mixed blessing. AA batteries are easy to replace anywhere and even rechargeable NiMH types are inexpensive, but expect lower battery life per set (often around 150 shots). This camera may be better for occasional use unless you’re packing lots of spares.

Both accept SD/SDHC cards with one card slot, simplifying storage and image transfer, but the Olympus includes an HDMI port (for easy TV viewing), whereas the Pentax does not.

Video and Creative Modes: Beyond Still Photography

Both cameras record video at 720p HD (1280 x 720) at 30 fps, but there are differences in codec and features.

The Olympus records in H.264, a compression standard that balances quality and file size nicely, while the Pentax uses Motion JPEG, which tends to produce larger files with marginally less efficient encoding.

Neither supports advanced video features like external microphones, 4K, or high frame rates, which is expected given their vintage. But Olympus also supports timelapse recording - a neat creative bonus for those wanting to experiment with motion without investing in a dedicated setup.

Neither camera supports manual exposure in video mode, nor do they offer silent shutters or focus peaking for video. So if video is your primary focus, consider modern alternatives.

Environmental Durability and Weather Sealing: Should You Worry?

Both cameras lack weather sealing or ruggedization features such as waterproofing or dustproof casing - typical for budget compacts from their era.

If your photography often takes place in challenging weather, both warrant careful handling or extra protection.

Price to Performance: What Your Buck Buys Today

Vintage models like these have found new life on the used market or among collectors and budget buyers.

The Olympus SP-800 UZ originally retailed around $270 and the Pentax Optio E70 around $140.

Today, prices vary but reflect this gap - Olympus commanding roughly twice the Pentax's price due to its zoom reach, autofocus speed, and additional features.

Are those features worth it?

Absolutely - if you want a versatile superzoom compact that's capable across a broad swathe of use cases without the need to upgrade lenses or carry heavy gear.

If budget is tight and your photography needs are casual, simple snapshots, and you value small size above all, the Pentax offers basic, reliable performance at a very low entry point.

Putting It All Together: Who Should Buy Which?

To help wrap up this exhaustive comparison, here’s how I’d break down recommendations based on my hands-on testing and technical analysis:

• For the avid travel photographer or casual wildlife spotter who needs zoom versatility, better control, and faster autofocus - Olympus SP-800 UZ is the clear winner. It thrives across genres from landscape to portrait, sports to macro (yes, it even offers a 1 cm macro mode!), thanks to its flexible zoom, sensor size, and image stabilization.

• For beginners, budget-conscious buyers, or those wanting a truly pocketable everyday camera with simple operation and decent image quality - the Pentax Optio E70 fits the bill. It’s especially suited for street photography, casual snapshots, or as a secondary camera for times when weight and size trump all.

Specialty Use Cases: Portraits, Landscapes, and Beyond

• Portrait photography: The Olympus’s wider maximum aperture and longer zoom mean you can craft images with nicer background blur and better eye detail, even though backgrounds won’t rival DSLRs or mirrorless with fast primes. Pentax struggles here due to shorter zoom and smaller aperture.

• Landscape photography: Olympus’s higher resolution and dynamic range edge out Pentax, but neither offers weather sealing. Neither choice replaces dedicated DSLRs at the sharpness/dynamic range end but will satisfy in good lighting.

• Wildlife/sports: Olympus’s 10 fps burst and AF tracking give it a clear advantage for capturing action.

• Street photography: Pentax’s pocket size shines. Olympus would be bulkier, but still manageable with practice.

• Macro photography: Olympus offers focus down to 1 cm - impressively close for a compact - allowing some creative macro shooting.

• Night and astro: Both falter due to small sensors and CCD limitations.

• Video enthusiasts: Olympus’s H.264 encoding and timelapse recording add creativity.

• Professional work: Neither is pro-level, but Olympus’s reliability and expanded feature set edge ahead for casual pro use or backup.

Final Thoughts: Nostalgic Workhorses Worth Considering

In the grand scheme, both cameras serve as time capsules from the late 2000s compact camera era - each with its personality and limitations.

What they've taught me after days spent in the field is that camera selection boils down to your photography style and priorities:

• Want reach, control, and a do-it-all compact with surprising speed? Olympus SP-800 UZ is a bargain hunter’s superzoom champ.
• Looking for simplicity, ultra portability, and very casual snapping? Pentax Optio E70 will help you capture moments without fuss.

Neither replaces modern mirrorless cameras, but each holds a niche for enthusiasts who appreciate compact form factors, classic designs, and distinct shooting experiences.

Whichever you choose, I recommend buying used tested units with original batteries and checking optical components carefully - aging compact cameras can hide sensor dust or zoom wear.

So pack accordingly, charge up, and get ready to make the most of these humble but capable cameras.

Happy shooting!
