Olympus VR-340 vs. Pentax Optio S1: A Practical Comparison for Small Sensor Compact Enthusiasts

When browsing the compact camera aisle - or the dusty digital archives, as might be the case with these slightly veteran models - two small sensor compacts stand out for consideration: the Olympus VR-340 and the Pentax Optio S1. Both were announced around the same era (early 2010s), share the common ground of fixed-lens, compact designs with 1/2.3" CCD sensors, and promise decent zoom ranges for travelers and casual shooters alike.

But how do they truly stack up if you were to put them through the paces today? What does each bring to the table for portrait, travel, or even macro fans? And crucially, for the budget-conscious photographer looking for a handy pocket camera, which one should get your attention?

Having tested both thoroughly in diverse shooting scenarios over the years (plus some extended lab work), I’ll walk you through the essential differences - balancing technical specs, real-world performance, and where they fit into today’s photography workflows.

First Impressions: Handling, Build, and Controls

Picking up the Olympus VR-340 and the Pentax S1 side by side, the first noticeable difference is their physical footprint and ergonomics. The Olympus measures a svelte 96x57x19mm and weighs a mere 125g, while the Pentax stretches a bit to 114x58x28mm, tipping the scale at 157g. Not huge disparities, but Olympus edges out as the more pocket-friendly option.

This also reflects in the grip and button placement. The Olympus VR-340 adopts a simplified control layout with no manual focus and minimal customizability, making it very appealing for point-and-shooters wanting to compose and shoot quickly. Pentax’s S1, on the other hand, includes manual focus capability and a slightly more tactile shutter button feel, appealing more to photographers who appreciate a bit of hands-on control, even within the constraints of a fixed lens compact.

Though neither offers weather sealing or robust durability features, both cameras feel solid for casual use but won’t withstand rough outdoor abuse. Ergonomically, the Olympus’s slimmer profile makes it more of an easy grab-and-go, whereas the Pentax offers a tad more bulk but with some manual focus flexibility as a trade-off.

Moving over controls...

Top views reveal Olympus’s simplistic, uncluttered approach - an accessible command dial but no dedicated dials for aperture or shutter priority (those modes are absent). Pentax is similarly straightforward but with added physical manual focus rings and button combinations that hint at more experienced user engagement, despite lacking true exposure mode control.

Both have no electronic viewfinder, relying solely on their LCD screens for framing, which brings us nicely to the display analysis.

Viewing and Composing: LCD Screen and User Interface

The Olympus VR-340 sports a 3-inch fixed TFT LCD with 460k-dot resolution. This screen offers a bright, reasonably sharp preview, crucial in outdoor bright conditions where reflex glare can be frustrating. The Pentax S1 uses a smaller 2.7-inch screen at 230k dots but incorporates an anti-reflective coating, which surprisingly helps in direct sunlight even though the resolution is lower.

Neither camera has a touchscreen or articulating display, which isn’t a surprise given their vintage class. Live View is supported on both, but only the Pentax offers it with manual focus assist, a point in its favor for more precise composition or macro work.

I found the Olympus screen’s higher resolution simply makes focusing and previewing images more comfortable during casual shoots, but Pentax’s screen glare reduction adds tangible value in situations under harsh lighting.

Sensor Technology and Image Quality: The Heart of It All

Both cameras use a 1/2.3" CCD sensor measuring approximately 6.17 x 4.55mm and roughly 28 mm² in area. This sensor size, common among compact cameras of that period, imposes inherent limits on dynamic range, low-light noise control, and detail resolution compared to modern larger-sensor models.

Olympus VR-340 offers a slightly higher resolution of 16 megapixels, yielding max images at 4608 x 3456 pixels, while the Pentax S1 has 14MP with 4288 x 3216 pixels.

In practice, resolution gains between 14MP and 16MP on such tiny sensors are marginal - you’re unlikely to notice major detail differences unless cropping heavily.

However, the Pentax boasts a higher max ISO of 6400 compared to Olympus’s top native ISO of 3200. This suggests better low light sensitivity potential in the Pentax, although extensive testing reveals that noise levels at high ISOs in both remain quite significant. Neither camera is a night photography champ, but if you occasionally need to push ISO, the Pentax S1 flexes a bit more.

Shooting RAW is missing from both models, reinforcing their role as casual shooters - this limits advanced post-processing possibilities and color grading, a notable con if you seek serious image control.

Antialiasing filters degrade some fine detail but help prevent moiré in these fixed lens compacts. Color depth and dynamic range metrics aren’t officially available for either due to their age and positioning at the entry level.

Autofocus and Focusing Performance: Speed and Accuracy Face-Off

Critically for any photographer - especially street, wildlife, or sports shooters - how does autofocus perform?

Both Olympus and Pentax rely on contrast-detection AF systems, which are inherently slower than phase-detection used in DSLRs or mirrorless models. Neither is built for blazing speed bursts or snappy continuous tracking; burst shooting is not supported on Olympus and limited to 1 fps on the Pentax, emphasizing their suitability for leisurely shots.

The Pentax S1 uniquely offers manual focus override, facilitating more deliberate macro or creative shots. Its AF is set to 9 points, promising somewhat finer area locking compared to Olympus’s unspecified number of points but face detection capability (Olympus has affacedetection but Pentax lacks it).

For portraits, Olympus’s face detection can be handy in framing and exposing human subjects, while the Pentax may require manual focus efforts or reliance on centerweighted metering.

Neither camera is designed for demanding tracking of fast-moving subjects (sports or wildlife), but for casual wildlife or pets, both can satisfy basic needs - though Olympus’s stabilizer may help a bit in telephoto reach steadiness.

Lens and Zoom Capabilities: Reach and Flexibility

Here’s where their fixed lenses diverge in a telling way:

• Olympus VR-340: 24-240mm equivalent (10x zoom), f/3.0–5.7 aperture
• Pentax S1: 28-140mm equivalent (5x zoom), f/3.5–5.5 aperture

The Olympus packs a significantly longer zoom range, excellent for travelers or anyone wanting wide landscape capability plus considerable telephoto reach to capture distant subjects without carrying multiple lenses. However, higher zoom factors often mean optics sacrifice some sharpness and low-light performance at max telephoto ranges.

Pentax’s shorter zoom range appears less ambitious but often translates into better optical quality and wider maximum aperture at the tele end, a subtle edge when shooting in dimmer conditions.

Neither lens supports external flash units, which, combined with built-in flash ranges (4.8m for Olympus, 3.9m for Pentax), limits advanced lighting options.

Image Stabilization: The Unsung Hero for Handheld Shots

Both cameras employ sensor-shift stabilization housed within the body, which is commendable for their class. Olympus’s system typically performs well to steady shots during moderate zooms or low-light handheld shooting.

During my tests, Olympus offered steadier shots at the 240mm equivalent telephoto range, reducing the typical handshake blur associated with long zoom comps. Pentax’s stabilization is present but less effective at extreme focal lengths.

If you prioritize telephoto handheld stability - say for casual wildlife or event snapshots - the Olympus’s image stabilizer is a winning feature.

Video Capabilities: Modest but Serviceable

Neither camera positions itself as a capable video performer, but both record HD video at 1280x720p at 30 fps. Formats are limited to Motion JPEG, which leads to relatively large file sizes and less editing flexibility.

Neither camera packs microphone or headphone ports, so audio is captured through built-in mics only, limiting sound quality and control.

For casual home movies or quick social media clips, either is fine, but avoid expecting the fluidity or pro functionality enabling features available on current compacts or mirrorless cameras.

Battery, Storage, and Connectivity: Practical Considerations

Pentax S1 offers a respectable 260 shot battery life rating, thanks partly to its Battery Pack D-LI92. Olympus VR-340’s battery life isn’t specified but is known to fall in similar entry-level compact ranges.

Both support standard SD/SDHC/SDXC cards, but Pentax adds internal storage capability - a minor convenience if you forget your card.

Wireless connectivity is almost nonexistent: Olympus supports Eye-Fi cards for wireless transfer, a nice little touch for instant sharing back in the day, whereas Pentax has no wireless features. Neither supports Bluetooth, NFC, or modern fast transfer technologies.

USB 2.0 and HDMI ports are present on both for data and external display connectivity but are relatively slow by today’s standards.

Performance by Photography Genre: What Fits Best?

The real question is how do these two small compacts adapt to the many photographic interests enthusiasts might pursue? Here's a breakdown after exhaustive field tests and lab reviews:

Portrait Photography

For casual portraits, Olympus’s face detection is a useful assist, though aperture control limitations and sensor size constrain bokeh and depth-of-field control. Skin tones render naturally but with moderate noise in indoor lighting.

Pentax’s manual focus helps to nail focus on eyes if you take time, but lack of face detection and lower native ISO flexibility limits handheld low-light portraits.

Landscape Photography

The Olympus VR-340’s 24mm wide-angle and superior resolution gives it an advantage for sweeping scenes. Dynamic range is modest but common for 1/2.3" sensors.

Pentax’s lesser wide-angle reach holds it back slightly, while its anti-reflective LCD helps composition in bright conditions. Neither camera has weather sealing, so caution in harsh environments is advised.

Wildlife Photography

Olympus wins for wildlife snaps largely because of its 240mm telephoto range and stronger image stabilization, although AF speed is slow on both.

Pentax’s 140mm max zoom is less flexible but manual focus aids for static wildlife or macro flora shots.

Sports Photography

Neither ideal for sports given slow autofocus, low continuous shooting (Olympus has none, Pentax a mere 1 fps). However, Olympus’s stabilization and face detection can help capture children’s activities and casual sports moments.

Street Photography

Portability and discretion favor Olympus's smaller size and lightweight design. The faster zoom is helpful in street candid photography.

Pentax’s anti-reflective screen and manual focus are pluses for urban shooters who want more control despite the camera’s bulk.

Macro Photography

Pentax has a 1cm macro focusing range, superior to Olympus’s unspecified macro capability. Manual focus on the Pentax allows precise focusing in close work.

If macro detail is a priority, choose the Pentax.

Night and Astro Photography

Limited low light capabilities on both. Pentax’s ability to shoot at ISO 6400 should theoretically help, but noise proves intrusive at high ISO levels.

Neither camera supports long exposures or bulb modes necessary for serious astrophotography.

Video Work

Both cameras offer 720p HD video with no advanced codecs or audio inputs.

Opt for Olympus if you want marginally better stabilization during handheld video, but keep expectations limited.

Travel Photography

Olympus’s longer zoom, lighter weight, and better LCD make it a natural travel buddy for broad coverage.

Pentax’s extra battery life and internal storage provide backup perks, but the larger size can be a drag.

Professional Use

Neither camera aligns tightly with professional workflows - no raw shooting, limited manual controls, or rugged build quality.

They serve best as backup cameras or for casual documentation.

Final Verdict and Recommendations

Having pored over both from technical datasheets, matched shooting tests, and practical user scenarios, my conclusions are:

• Choose Olympus VR-340 if you want a lightweight, ultra-zoom compact with decent image stabilization, face detection, and intuitive controls optimized for travel, landscape, and casual portrait work. Its longer zoom reach and higher resolution justify its budget-friendly price point well.

• Opt for Pentax Optio S1 if you desire more manual focus control, macro capabilities, slightly better low-light ISO range, and internal storage - valuable for enthusiasts dabbling in close-ups or needing a bit more operational control in a compact shell.
