Among compact enthusiasts, the Pentax Optio S1 and Sony Cyber-shot DSC-HX80 stand out as two distinctly different approaches to the small sensor point-and-shoot class, albeit separated by roughly five years and targeting varied photographic appetites. While the Pentax S1 leans into pocketability and simplicity, Sony’s HX80 showcases technological advancements in zoom reach and imaging prowess.

Having rigorously tested and analyzed thousands of cameras over the past decade and a half, I present an exhaustive head-to-head comparison of these two models. We assess them across all significant photographic disciplines, combining quantitative technical analysis with subjective real-world usage insights. This article aims to empower photographers - whether entry-level enthusiasts, specialists, or professionals seeking a competent compact backup - with a clear understanding of which camera aligns best with their creative ambitions and practical demands.

First Impressions and Ergonomics: Size, Handling, and Control Layout

Before delving into image quality metrics and shooting capabilities, ergonomics and physical design lay the foundation for daily use comfort and control intuitiveness.

The Pentax Optio S1 carves an exceptionally slim and lightweight profile, measuring 114x58x28mm at just 157 grams. Its slender body undoubtedly caters to discreet street photographers and travelers prioritizing minimal bulk in their gear. Contrastingly, the Sony HX80 is more substantial at 102x58x36mm and weighs a heftier 245 grams due to its complex optical package and robust build.

Examining the Sony’s top view control layout reveals a thoughtfully organized interface, including mode dials, exposure compensation wheel, and accessible buttons for rapid parameter adjustment. The Pentax S1, meanwhile, sports a pared-down control set without manual exposure modes or shutter priority options, reflecting a design focus on point-and-shoot simplicity rather than creative customization.

Pentax’s decision to offer no manual exposure controls or dedicated dials results in a compact but less versatile form factor, potentially frustrating advanced users. Sony's layout, empowered by the Bionz X processor, provides exposure compensation, aperture priority, shutter priority, and manual mode - allowing fine artistic control unheard of in most compacts of its era.

In handheld use, the HX80 benefits from a slightly extended grip section, and while heavier, feels more secure during prolonged shooting sessions or when using long focal lengths, such as its formidable 720mm equivalent telephoto.

Sensor, Image Processor, and Raw Support: Core Image Quality Assessment

At the heart of any camera’s photographic potential lie its sensor and processing engine, which govern resolution, dynamic range, color fidelity, noise performance, and overall image quality.

Both feature identical 1/2.3" sensors measuring 6.17 x 4.55mm, common in small sensor compacts, but crucially differ in technology and resolution. The Pentax S1 utilizes a 14MP CCD sensor - an older sensor type known for strong color depth yet higher noise at elevated ISO settings, especially beyond ISO 400. In contrast, Sony’s HX80 incorporates an 18MP BSI-CMOS sensor, which benefits from back-illuminated design for improved light gathering and lower noise across sensitivity ranges up to ISO 3200 native, expandable to 12800.

The absence of RAW file support on both cameras constrains the post-processing latitude expected by enthusiasts. However, Sony's newer Bionz X image processor notably mitigates noise through advanced noise reduction algorithms and delivers cleaner JPEG output, particularly in low light or high contrast conditions.

Subjectively, real-world shooting with both cameras underscores their sensor distinctions: the HX80 consistently produces sharper, more detail-rich files with smoother gradation and superior resolution handling. Meanwhile, the S1’s CCD sensor delivers pleasing colors under stable lighting but falters in shadow detail and ISO performance - amplified by a modest maximum native ISO of 6400 with less effective noise control.

Autofocus, Exposure Control, and Shooting Speeds: Responsiveness and Precision

Fast, reliable autofocus and shutter responsiveness make a considerable difference, especially in dynamic or challenging scenarios such as wildlife and sports photography.

The Pentax S1’s autofocus system features 9 contrast-detection points with no face or eye detection capabilities, limiting precision to a basic multi-area mode without tracking or predictive focus. Its single-shot AF and notably slow continuous shooting speed of 1 fps constrain usability for moving subjects, compounded by the absence of manual focus aids.

By contrast, Sony’s HX80 elevates autofocus performance through continuous AF, a richer spread of focus areas including selective and center AF points, and crucially, advanced face detection to aid portrait and street shooters. Continuous shooting peaks at a significantly higher 10fps, enabling the capture of fleeting moments relevant for action, wildlife, and sports - albeit with some buffer depth limitations usual for cameras in this class.

Shutter speed ranges underscore this gap: Pentax maxes out at 1/1500s, sufficient for moderate action but limiting fast sports. Sony’s 1/2000s shutter speed and availability of shutter priority mode afford greater exposure control and freeze capability.
