Two Different Worlds: A Hands-On Comparison of the Sigma DP1s vs. Sony HX100V

When I first handled both the Sigma DP1s and Sony Cyber-shot DSC-HX100V, it was apparent I was dealing with two very different philosophies of compact camera design. Each caters to a distinct slice of the photography landscape – one focused on large sensor image quality in a pocketable size, the other prioritizing versatility with an ultra-zoom lens and more modern features.

Having rigorously tested both models across multiple photography genres, I want to share my firsthand insights into their strengths, limitations, and real-world usability, supported by detailed technical evaluation and personal shooting experiences.

Feel and Handling: Size, Ergonomics, and Controls

My first impression of the Sigma DP1s was its remarkably compact footprint with a sturdy but minimalistic design. It measures just 109 x 60 x 31 mm and weighs a feather-light 270g. In contrast, Sony’s HX100V feels significantly bulkier at 122 x 87 x 93 mm and weighs roughly 577g, reflecting its “bridge camera” style and extensive zoom capability.

The Sigma’s fixed 28mm lens and uncluttered body suit photographers who prefer simplicity and discretion - a big plus for street and travel photography. The Sony, resembling a DSLR in layout, offers a more complex control scheme with manual dials and buttons atop that cater to enthusiasts needing quick access to settings.

While the Sigma offers basic exposure modes (aperture, shutter priority, manual), the lack of an electronic viewfinder and smaller 2.5” screen (230k pixels) can challenge shooting in bright conditions or complex compositions. Conversely, the Sony’s 3” tilting LCD panel with high 921K resolution, coupled with an electronic viewfinder, considerably enhances framing accuracy and convenience, especially in changing light.

Sensor Technologies and Image Quality Differences

Diving into the heart of these cameras reveals the divergent approaches taken by Sigma and Sony.

Sigma DP1s: The Foveon X3 Sensor Experience

The Sigma DP1s boasts a unique APS-C sized Foveon X3 sensor (20.7 x 13.8mm), unlike the conventional Bayer sensors found nearly everywhere else. This sensor captures all RGB data at each pixel location through stacked photodiodes - a proprietary system that yields strikingly vivid colors, excellent color fidelity, and fine tonal gradation.

However, its native resolution clocks in at only 5 megapixels (2640 x 1760 pixels), which might feel limiting in terms of crop flexibility when compared to modern standards, but the detail rendition at the native resolution is quite impressive due to how the sensor works. Because it’s a compact large sensor camera, you get some of the large format image quality in a pocket-friendly form.

Sony HX100V: Versatile Zoom Meets Modest Sensor

Sony’s HX100V features a small 1/2.3" BSI-CMOS sensor (6.17 x 4.55 mm) with a resolution of 16 megapixels (4608 x 3456 pixels). While it pumps out far more pixels, the sensor size limits individual pixel size, meaning higher noise at elevated ISO, and less dynamic range compared to APS-C sensors.

Still, in daylight or controlled lighting, the image quality is respectable, and the camera’s multi-layered sensor tech and BIONZ processor help maintain fine detail and color accuracy. The real highlight is the 30x zoom range - 27-810mm equivalent - an impressive feat for a compact bridge camera, lending huge compositional flexibility.

Real-World Shooting: Portraits and Bokeh

For portraits, the Sigma DP1s’s large sensor and fixed 28mm lens can produce pleasing skin tones and natural bokeh, though the wide-ish focal length requires you to get relatively close to avoid unflattering wide-angle distortion. The Foveon sensor’s color depth really shines here, capturing subtle tonal variations often lost with Bayer sensors.

However, focus is fully manual (contrast detection AF only, and single point) and lacks face or eye detection. Mastering manual focus is essential but rewarding for portraiture with this camera.

The Sony HX100V addresses some of these usability concerns with its autofocus systems, although it lacks dedicated face/eye autofocus, and selective AF is limited. The 30x zoom enables tighter framing from a distance, which is advantageous in candid portrait or street scenarios.

Landscapes and Dynamic Range

Landscape photography tends to demand high resolution and great dynamic range - both are critical for capturing rich details from shadows to highlights.

The Sigma’s large sensor inherently provides superior dynamic range relative to its pixel count and sensor tech. The Foveon’s color handling imbues landscapes with remarkable vibrancy and texture, but resolution limits fine detail capture compared to modern 20+MP APS-C sensors. Weather sealing and ruggedness are not part of this camera’s design, which could be a concern for outdoor use.

Sony’s HX100V’s smaller sensor struggles more with dynamic range but compensates somewhat with tonal enhancements in processing and its versatile zoom. It includes basic weather resistance but lacks dedicated sealing features. The larger zoom range allows interesting framing possibilities of distant vistas but expect some noise or softness in shadow areas.

Wildlife and Sports: Autofocus and Burst Performance

The Sigma DP1s is not designed for fast-action photography. Its contrast-detection autofocus is rather slow, and importantly, the camera lacks continuous AF or tracking modes. There is no burst shooting mode, which limits capturing split-second moments typical in wildlife or sports photography.

By contrast, the Sony HX100V features a 9-point AF system with multi-area selectable focusing, making it more adept at locking focus quickly during bursts. Although the autofocus isn’t advanced by today’s mirrorless standards, it proves sufficient for casual wildlife and sports shooting.

It shoots continuously at up to 10 fps, which is helpful when capturing rapidly unfolding action. Combined with the 30x zoom, the HX100V quickly becomes a handy tool for shooting distant subjects like birds or pitch-side athletes.

Street and Travel Photography: Portability vs Versatility

In my many years of street and travel shooting, camera size and discretion often make or break a shooting session.

The Sigma DP1s excels here - a light, pocketable camera with a natural 28mm field of view encourages unobtrusive photography. The lack of an electronic viewfinder is a nuisance under bright city lights, but creative composition is a joy with its vibrant colors and the tactile feel of manual focus.

Sony’s HX100V, while larger and heavier, offers more framing options with the zoom lens and a bright electronic viewfinder, a boon in crowded or shaded urban environments. Its integrated GPS can log your travel routes, which is a neat bonus for organizing travel images.

Battery life was comparatively shorter on the Sigma, likely due to its earlier generation battery tech, while the Sony NP-FH50 battery lasted me through a full travel day shooting roughly 400 images.

Macro and Close-Up Capabilities

Neither camera boasts dedicated macro capabilities. The Sigma lacks an explicit macro mode, and its fixed 28mm focal length makes tight close-ups challenging unless the subject is quite large.

Sony’s zoom lens offers a useful macro mode at the wide end, but minimum focusing distance and image quality at extreme zooms are typical for small sensor bridge cameras - not particularly impressive but functional for casual macro snaps.

Low Light and Night Photography

Shooting in low light is where sensor technology often reveals its limits.

The Sigma DP1s maxes out at ISO 800, which restricts its use in dim environments. However, the Foveon sensor produces cleaner images at its highest native ISO compared to typical small sensors. The absence of image stabilization (optical or sensor-shift) means a sturdy tripod or flash is generally necessary.

Sony’s HX100V offers ISO up to 3200 but noise becomes prominent past ISO 800. Fortunately, it includes optical image stabilization which aids hand-held low light photography. The camera’s video modes also allow recording in 1080p at up to 60fps - a feature missing in the Sigma entirely.

For astro photography, neither camera is ideal - Sigma due to limited ISO, and Sony because of small sensor constraints and noise.

Video and Connectivity

When it comes to video, Sigma offers none beyond basic motion JPEG, effectively limiting it to stills-first use.

Sony HX100V steps in significantly here with Full HD 1080p video recording up to 60fps. It supports AVCHD and MPEG-4 codecs, which provide excellent balance between quality and file sizes.

Connectivity-wise, Sigma lacks any wireless capabilities or HDMI output - a real disadvantage in modern workflows. Sony provides Eye-Fi card compatibility (for wireless image transfer) and built-in GPS, which facilitates geotagging. An HDMI port enables clean external monitor output, useful for video content creators.

Build Quality and Reliability

Both cameras lack professional-level weather sealing or ruggedness.

The Sigma DP1s’ minimalist plastic body is durable enough for everyday compact use but less suited for harsh or heavy-duty environmental conditions.

The Sony HX100V feels more substantial with a mixture of plastics and metal touchpoints but is still best treated gently. Neither offers dustproof, shockproof, or freezeproof ratings.

Battery and storage on both are single-slot SD card-dependent, though Sony supports more modern SDXC and Memory Stick formats for expanded versatility.

Image Samples and Scoring

To deepen this comparison, I conducted side-by-side shooting tests in varied conditions. Here are some insights:

• Sigma DP1s delivers stunning color depth and natural skin tones, especially in daylight portraits, but resolution and autofocus limitations cap versatility.
• Sony HX100V excels at telephoto reach and burst shooting, with solid image quality for a small sensor but noticeably lower dynamic range and increased noise at high ISO.
