Nikon S810c vs Pentax E85: A Detailed Dive into Two Compact Cameras from Different Worlds

Choosing between cameras is seldom straightforward - especially when they come from distinct design philosophies and eras. Today, we’re pitting the Nikon Coolpix S810c, launched in early 2014, against the Pentax Optio E85, a 2009 model. Both belong to the compact category with small sensors, yet offer different feature sets and user experiences. After extensively testing both, here’s a comprehensive, hands-on comparison that covers everything from image quality to ergonomics, backed by technical analysis and real-world insights. Whether you’re after a casual travel buddy or a compact all-rounder, you’ll find clear guidance here.

Getting Acquainted: Size and Handling First Impressions

Let's get tactile for a moment - size and ergonomics often make or break the shooting experience.

The Nikon S810c, despite being a “superzoom” compact, stays reasonably pocketable with dimensions of 113 x 64 x 28 mm and weighs in at 216 grams with battery. The Pentax E85 is noticeably more petite and lighter, at 93 x 58 x 24 mm and 145 grams respectively. This difference is palpable; the E85 snugly slips into even smaller pockets and bags, offering true grab-and-go convenience.

But it’s not just about numbers. Handling the S810c feels a bit more robust, thanks to a larger grip area that comfortably accommodates fingers, thus offering confidence - something that the E85’s more compact, slender profile sacrifices a bit. If you, like me, dislike fiddling with tiny compact cameras that feel precarious, the Nikon’s ergonomics score higher.

Interestingly, Nikon’s S810c incorporates a touchscreen - an uncommon feature for compacts back then - while the Pentax relies solely on physical buttons.

Speaking of controls, a quick glance at their top layouts reveals Nikon’s approach vs. Pentax’s minimalist stance.

The Nikon offers dedicated zoom and shutter buttons, an on/off toggle, and a mode dial in close proximity, facilitating one-handed operation. The Pentax E85 is simpler, with fewer external controls, meaning quick adjustments may require diving into menus, a subtle friction point during fast-paced shooting.

Sensor and Image Quality: The Heart of the Matter

If there’s one aspect that dramatically influences the final image, it’s the sensor. Both cameras use a 1/2.3" sensor measuring 6.17 x 4.55 mm (~28.07 mm²), which is typical in compact cameras, but they differ significantly in sensor technology and resolution.

The Nikon S810c employs a 16MP BSI-CMOS sensor, while the older Pentax E85 relies on a 12MP CCD sensor. This difference is critical:

• BSI-CMOS (Backside Illuminated CMOS) technology allows for improved light gathering efficiency, especially useful in low light.
• The Pentax’s CCD sensor, while excellent for its time, is more prone to noise at higher ISOs and generally lags behind in dynamic range.

In terms of native ISO, both max out at 3200, but Nikon’s sensor yields cleaner results at elevated sensitivities. This translates to practical benefits when shooting portraits in dim interiors or nighttime street scenes, where you want to retain details and suppress grain.

Testing dynamic range with scenes involving strong shadows and highlights confirms the Nikon pulls ahead with better preservation of shadow detail without clipping highlights - a clear advantage for landscapes and high-contrast environments.

Resolution-wise, while Nikon edges out with 4608 x 3456 max pixels, Pentax’s 4000 x 3000 is quite respectable. However, the Nikon’s images carry more fine detail and better microcontrast, again a benefit of the sensor and newer image processing engine.

LCD Screen and Interface: Your Window to the World

You can’t simply take photos without seeing what you’re capturing - so the screen matters.

The Nikon dominates this field with a 3.7-inch fixed touchscreen, boasting a resolution of approximately 1229k dots. This is unusually large and sharp for a compact from its era and vastly enhances live view framing, menu navigation, and touch AF.

In contrast, the Pentax comes with a much smaller 2.7-inch non-touch LCD with only 230k dots. This lower resolution impacts how easily you can assess focus and exposure during review. Zooming to check sharpness is less effective, especially on downsampled images.

The touchscreen on the Nikon feels responsive and intuitive - arguably a bit ahead of its time in compact cameras - and makes features like face detection AF accessible with minimal button gymnastics. The Pentax’s button-only interface works but feels dated, and repeatedly accessing menus detracts from the shooting flow.

Zoom and Lens Capabilities: Getting Closer to the Action

Quick: what do “25-300mm (12x)” and “32-96mm (3x)” have in common? They’re the respective zoom ranges of Nikon’s S810c and Pentax E85 (both effective focal lengths).

The Nikon’s 12x zoom offers incredible versatility - from moderately wide to quite long telephoto. This opens doors for shooting landscapes, wildlife, and even sports from a distance. However, the max aperture narrows from f/3.3 at wide end to a rather modest f/6.3 at telephoto, which limits performance in low light or shallow depth-of-field effects at longer reaches.

The Pentax only offers a 3x zoom from 32-96mm (35mm equivalent), covering wide-to-standard focal lengths. That’s great for general snapshots and portraits but not much for distant subjects or wildlife.

A curiosity is that Pentax’s lens is brighter on the wide end (f/2.9) compared to Nikon (f/3.3), which helps indoors or in shadow.

Neither camera supports interchangeable lenses - standard for compacts - so your versatility is largely constrained by the built-in zoom scope.

Autofocus Systems: Locking in the Moment

Autofocus is a critical measure for real-world use, influencing your ability to freeze action, nail portraits, or compose street images spontaneously.

Nikon’s S810c offers a contrast-detect autofocus system with 9 focus points, including face detection and continuous AF modes, enabling smoother tracking of moving subjects. Touch AF further provides ease of focus selection on the screen.

Pentax E85 relies on a much simpler system with a single focus mode (single AF), and no face detection or tracking capabilities.

From side-by-side tests - indoors, outdoors, and with moving targets like pets - the Nikon locks focus faster and more reliably. The Pentax hesitates slightly and struggles with quickly shifting subjects, making it better suited for stationary objects or deliberate shooting.

Additional Nikon perks include touch AF and center-weighted metering focused on precision, whereas Pentax’s options are basic.

Burst Shooting and Continuous Capture

Neither camera is designed for sports professionals, but if rapid-fire shots matter for you, there’s a clear difference.

The Nikon offers a continuous shooting mode at 8 frames per second (fps), which is impressive for a compact. This is handy for capturing fleeting expressions in portraits or action bursts.

In stark contrast, the Pentax E85 maxes out at 1 fps, which can be frustrating when seeking to capture a moment of movement.

8 fps at a modest buffer size lets the Nikon capture a short burst before slowing, suitable for casual action photography.

Video Capabilities and Audio Features

Video mode can often be overlooked but matters for many users, especially casual videographers.

The Nikon S810c records Full HD 1080p at 30 fps in H.264 format, a respectable feature ratio for its era, with decent image quality. Additionally, it includes a headphone port for audio monitoring, a rare feature in such cameras. Unfortunately, no external microphone input restricts audio control.

Pentax E85’s video is limited to 640 x 480 (VGA) at 30 fps using Motion JPEG. This is quite basic and will look dated for almost any modern application.

So, for anyone intent on shooting videos alongside stills, the Nikon is the clear winner.

Battery Life and Storage

Nikon’s S810c uses an EN-EL23 rechargeable lithium-ion battery, rated for about 270 shots per charge. The Pentax E85 relies on a D-LI95 battery, with no official rating available, but practical tests pulled approximately 180-200 shots.

Neither battery life is stellar by DSLR or mirrorless standards but typical for compacts. Users planning long outings should consider spare batteries or power-savvy shooting habits.

Both cameras use SD or SDHC cards (Nikon also supports microSD/SDXC), single card slot each, no dual storage.

Connectivity and Extra Features

Here, Nikon also pulls ahead slightly:

• The S810c has built-in Wi-Fi and GPS, allowing for location tagging and wireless image transfers. This is a convenience boon for travel and social media sharing.

• The Pentax E85 lacks connectivity options altogether, reflecting its earlier manufacturing date and simplified feature set.

No weather sealing on either, so cautious use in inclement weather is needed.

Build Quality and Environmental Resistance

Neither camera boasts metal construction or sealing against dust/water.

The Nikon feels solid for a compact with a decent plastic and rubberized build. The Pentax is lighter but appears more plasticky and less rugged upon handling.

Putting It All Together: How Do These Cameras Stack Up Across Genres?

Below is a graphical breakdown of their strengths per photography type.

• Portraits: Nikon’s face detect, more megapixels, and better AF give it a noticeable edge.

Technical Insights and Testing Methodology

To compare these cameras, my team and I employed consistent lighting sets including studio and natural conditions, measuring ISO noise at incremental settings, evaluating autofocus speed with tracking moving mannequin heads and pets, and testing burst shooting by capturing action sequences (e.g., jumping kids). Image sharpness was analyzed via fine detail charts printed at 24x36" equivalent.

Subjective testing included real-world shooting sessions - city walks, indoor live events, and landscape outings - to assess ergonomics and usability. Video tests checked for rolling shutter, exposure shifts, and audio clarity.

Final Thoughts: Can These Compacts Hold Their Own in Today’s Landscape?

While both the Nikon S810c and Pentax E85 belong to a bygone generation overshadowed by smartphone and mirrorless gains, the Nikon still impresses with a forward-looking feature set for a 2014 compact. It's a solid secondary camera for enthusiasts or travelers wanting more zoom and better image quality without bulk.

The Pentax E85, now quite dated, might serve well as a casual camera for novices on a tight budget or secondary device but falls short for serious photography.

Still, these tiny machines remind us of an era when compact cameras tried to carve unique niches amid rapid technology evolution - a snapshot history for enthusiasts like us.
