Nikon Coolpix S8100 vs Pentax MX-1: A Hands-On Comparison of Two Small Sensor Compacts

Having spent over 15 years personally testing a vast range of digital cameras - from flagship mirrorless systems to pocket-friendly compacts - I find it fascinating how two cameras occupying the same category can deliver notably different photographic experiences. Today, I’m diving deep into two small sensor compacts released a few years apart but still holding appeal for photography enthusiasts searching for a capable, travel-friendly camera with advanced controls: the Nikon Coolpix S8100 (2010) and the Pentax MX-1 (2013).

Both targeted at enthusiasts wanting more than a basic point-and-shoot yet not ready to commit to interchangeable-lens systems, these cameras offer unique takes on usability, image quality, and creative control. In this extended review, I combine extensive real-world shooting experience, rigorous technical analysis, and user-centric insights to help you decide which might fit your photography style and needs best.

Size and Handling: Comfort in Your Hands

Before unpacking image quality and performance, ergonomics and physical design often dictate how enjoyable using a camera is over extended shoots or travel days. The Nikon S8100 and Pentax MX-1 both come in compact packages but with divergent approaches to size and handling.

At first glance, the Nikon S8100 is noticeably more pocket-friendly and lightweight (180g vs 391g). Its slim 104x60x30mm frame slips easily in a jacket pocket, making it ideal for street photography or casual outings where minimal bulk is a priority. The rounded grip is subtle but sufficient for one-handed use, although I found it on the smaller side for larger hands after prolonged shooting.

In contrast, the Pentax MX-1 is chunkier and heavier, measuring 122x61x51mm. This heft translates into a more reassuring grip with pronounced textured surfaces and well-delineated control dials - something I immediately appreciated on wildlife and travel shoots where stable framing is critical. The MX-1’s retro-inspired body gives it a distinct tactile presence but makes it less discreet for street photography.

If you prize ultra-portability, Nikon’s S8100 edges out. For those who want confident handling and a camera that feels substantial in hand, the Pentax MX-1's build quality is more satisfying.

Top Controls and Interface: Ease and Intuition in Operation

Moving from feel to function, I explored how each camera handles in terms of their control layout and operational logic. Hands-on testing revealed marked contrasts reflective of their eras and target users.

The Nikon S8100 keeps things simple: a minimalistic top plate with a mode dial primarily aimed at casual users. There’s no manual exposure mode or dedicated aperture/shutter priority dials, limiting creative control for seasoned users. The buttons are small but logically grouped, with a clear record button for video and a zoom lever that doubles as a shutter release modifier.

By contrast, the Pentax MX-1 clearly targets enthusiast photographers. Its top deck boasts a dedicated aperture ring around the lens, a shutter speed dial on the right, and a mode dial with PASM modes alongside manual exposure compensation control. Buttons are tactile and well-spaced for one-handed adjustments. The MX-1's more complex control scheme demands a slightly steeper learning curve but rewards with precise, quick manual settings access - such as when shooting fast-moving subjects or challenging lighting.

If intuitive, fully manual control is your priority, the Pentax MX-1 shines as a serious enthusiast compact. If ease of use and a gentler learning curve appeal more, the Nikon S8100’s simplistic layout wins out.

Sensor and Image Quality: Size Matters - But There’s More

The heart of any camera remains its sensor and image processing pipeline. Both cameras sport 12MP sensors, but their sensor sizes and technologies are different: the Nikon S8100 uses a 1/2.3” BSI-CMOS sensor, whereas the Pentax MX-1 employs a larger 1/1.7” CMOS sensor.

A larger sensor typically means larger photosites, resulting in better light gathering, dynamic range, and less noise - especially important in low light or high-contrast scenes. The Pentax MX-1’s sensor area is about 41.5 mm², appreciably larger than the Nikon’s 28 mm². This difference is critical for image quality.

In various test shoots - including indoor portraits and twilight landscapes - the MX-1 consistently delivered cleaner images with richer colors and less chromatic noise above ISO 400. Its imager handles shadow detail and highlight roll-off with more finesse, evident in more natural skin tones and enhanced dynamic range - benefits further bolstered by the camera’s support for shooting RAW files, enabling deeper post-processing latitude.

The Nikon S8100, while competent in well-lit conditions, exhibited earlier noise degradation beyond ISO 400, coupled with more muted colors and slightly softer resolution noticeable in pixel-peeping comparisons. This is partly attributed to its smaller sensor and more compressed JPEG pipeline, made evident in camera-generated JPEGS since RAW isn’t supported.

While both cameras deliver respectable image quality for social media and casual prints, the Pentax MX-1 has the decisive edge for photographers prioritizing image fidelity and post-production flexibility.

LCD and Interface Usability: Reviewing Your Shots with Confidence

An often overlooked but critical factor is the rear LCD - the window to your compositions and settings review experience. Both feature a 3” screen of comparable resolution (~920k dots), yet their deployment and optical coatings differ.

The Nikon S8100 has a fixed LCD with no touch input. It’s bright and sufficiently contrasty in shaded environments but can struggle under direct sunlight - typical for its class and era. Its menu system feels straightforward but occasionally requires digging for less obvious settings, a tradeoff for simplicity.

The Pentax MX-1 offers a tilting TFT LCD with aftermarket coatings aimed at reducing glare, which I found helpful for framing tricky angles and shooting in bright conditions. While it still isn’t touch-enabled, the tilting functionality adds compositional flexibility - great for macro work or shooting from unconventional perspectives. Aside from that, the screen’s color rendition is rich and accurate, aiding in critical exposure and focus assessments.

For casual use, the Nikon’s fixed screen is adequate; enthusiasts who enjoy flexible framing and more precise review will gravitate naturally toward the Pentax MX-1’s tilt screen.

Autofocus and Speed: Capturing Fleeting Moments

Autofocus speed, accuracy, and burst performance are key for anyone shooting moving subjects - from kids and pets to wildlife and sports.

The Nikon S8100 uses contrast-detection autofocus with face detection but lacks continuous autofocus during burst shooting and manual focus. It offers a max continuous shooting rate of 10 frames per second, which is very commendable for a compact of its generation - though in my experience, AF tracking during burst was somewhat inconsistent, often causing missed focus on fast erratic subjects.

Pentax MX-1 ups the ante with 25 contrast-detection focus points, AF single, continuous AF, and face detection. Although its continuous frame rate is slower (1 fps), each frame was accurately focused, giving me better results for deliberate sequences rather than rapid bursts. The ability to manually focus and tweak exposure whilst observing histograms helped me nail subjects in challenging light.

If you’re chasing fast action and want high burst rates for image selection, Nikon’s 10fps is attractive but comes with AF limitations. For more controlled shooting sessions where precise focus matters, the Pentax MX-1 delivers superior AF accuracy and flexibility.

Versatile Lenses and Aperture Range: Reach and Creative Control

Lens specifications greatly influence what you can capture and how expressive your images can be.

• Nikon S8100: 30-300mm equivalent zoom (10x zoom range), aperture f/3.5-5.6
• Pentax MX-1: 28-112mm equivalent zoom (4x zoom range), aperture f/1.8-2.5

Nikon’s telephoto reach is impressive - 10x zoom covering everything from wide to super-telephoto, suitable for distant wildlife or sports where closeness is difficult. However, the tradeoff is a slower lens max aperture narrowing to f/5.6 at the tele-end, limiting low-light capabilities and bokeh control at longer focal lengths.

Pentax adopts a shorter zoom range but compensates with a significantly faster lens that starts at a bright f/1.8 and maintains f/2.5 at 112mm. This wide aperture enables exquisite shallow depth-of-field portraits and better low-light performance without cranking ISO excessively. The MX-1 also excels at close focusing (down to 1 cm) with pleasing magnification - facilitating compelling macro shots with natural background blur.

For photographers valuing reach and zoom versatility, Nikon’s 10x lens is a clear winner. Those prioritizing aperture speed, shallow depth of field, and macro capabilities will appreciate the Pentax MX-1's faster, more creative lens.
