Drawing from extensive hands-on testing and technical scrutiny accumulated over 15 years of camera evaluation, this article evaluates these models across multiple photographic disciplines and technical criteria, empowering you to make an informed decision tailored to your needs.

First Impressions: Design Language and Ergonomics

The Sigma DP3 Merrill stands out markedly in size and build compared to the ultra-slim Sony T110. Measuring 122x67x59 mm and weighing 330 grams, the DP3 Merrill exudes a robust presence typical of large sensor compacts, designed to offer stable handling, especially crucial during long exposures and manual focusing - features intrinsic to its use case. Conversely, the Sony T110’s ultracompact form factor (93x56x17 mm, 121 grams) exemplifies pocketability and discreet shooting but compromises on traditional camera ergonomics, favoring simplicity over extended-use comfort.

Ergonomically, the Sigma’s body affords an assured grip with dedicated manual controls, whereas the Sony’s diminutive size and shallow contours make it convenient for casual snapshots but less ideal for controlled, extended shooting sessions. The Sigma’s fixed 3-inch, 920k-dot non-touch LCD contrasts with Sony’s similar-sized but lower resolution 230k-dot Clear Photo LCD Plus with touchscreen - a modern interface enhancing user interaction. These choices hint at each camera’s intended audience: Sigma targets photographers valuing control and image fidelity, Sony appeals to casual shooters prioritizing ease and fun.

Sensor Technology and Image Quality: The Core Differentiator

At the heart of any camera lies its sensor - the foundation upon which all image quality depends. The Sigma DP3 Merrill is equipped with an APS-C sized Foveon X3 CMOS sensor (24x16 mm) boasting 15 megapixels true resolution (4704x3136 pixels). The Foveon’s unique multilayer design captures color information per pixel layer (red, green, and blue stacked), which has historically imparted superior color depth and microdetail compared to conventional Bayer sensors. The sensor area of 384 mm² is significant for a compact, allowing for exceptional image quality at base ISO.

In contrast, the Sony T110 features a much smaller 1/2.3-inch CCD sensor (6.17x4.55 mm), only 28.07 mm² in area, with 16 megapixels resolution (4608x3456 pixels). While the pixel count is comparable, the much smaller sensor size inevitably limits dynamic range, high ISO performance, and overall image fidelity.

Practically, this translates to the Sigma delivering images with superior tonal gradation, richer color reproduction, and lower noise at ISO 100–400, but with limited high-ISO flexibility given its native maximum ISO 6400. The Sony’s sensor is more susceptible to noise and tends to produce less vibrant images, especially in shadows and low light - typical of ultracompacts designed for daylight conditions.

Notably, the Sigma includes an antialiasing filter, which some photographers might consider unnecessary for its Foveon sensor, but it modestly reduces moiré without perceptible softness, balancing sharpness and artifact avoidance.

Lens Systems and Optical Performance

The Sigma DP3 Merrill’s fixed 75mm (equivalent) F2.8 prime lens is a highlight, offering a portrait-friendly telephoto perspective with high optical quality characteristic of Sigma’s renowned lens engineering. The 1× focal length multiplier implies a straightforward angle of view corresponding to 75mm in 35mm terms, emphasizing compression and background separation for portraits and detail work.

The Sony T110, by contrast, features a compact 27-108mm (4× zoom) f/3.5-4.6 lens designed for versatility in a small package. Its focal range covers wide-angle to short telephoto, accommodating landscapes and casual portraits but sacrificing aperture speed and thus background blur capabilities.

The fixed prime on the Sigma excels in sharpness, control over depth of field, and bokeh quality, especially at apertures near F2.8-F4. Meanwhile, Sony’s zoom is adequate for snapshots but struggles with low light and creative focus effects inherent to wider apertures.

Autofocus and Manual Control: Precision Versus Simplicity

One of the most glaring differences between these cameras lies in autofocus capabilities and focusing methods. The Sigma DP3 Merrill offers only manual focus, relying on the photographer’s skill augmented by a high-resolution screen and magnification aids. This choice reflects Sigma’s deliberate design philosophy prioritizing ultimate image fidelity and precision over speed or automation - they expect the user to focus deliberately and engage deeply with composition.

In contrast, the Sony T110 supports autofocus exclusively via contrast-detection with 9 focus points, including multi-area AF, suitable for quick framing and convenience but lacking sophistication like face detection or eye AF. It lacks manual focus, which limits creative control but simplifies operation for novices.

This difference manifests in practical use: Sigma users benefit from fine-tuned focus accuracy ideal for portraits, macro, and detailed work, while Sony users enjoy ease in spontaneous street or travel photography without worrying about focusing nuances.

Shutter, Burst, and ISO Range: Action Capture and Low Light

Speed and responsiveness often dictate suitability for genres like sports and wildlife. The Sigma manages a modest 4 frames per second burst but lacks continuous autofocus or tracking, making it less suited for fast-moving subjects. The absence of advanced AF modes (face, tracking) further restricts action photography.

Sony’s T110 offers just 1 frame per second continuous shooting and contrast-detection AF without tracking, limiting use in high-speed scenarios but acceptable for casual everyday photo-taking.

Regarding ISO ranges, Sigma’s native 100-6400 surpasses Sony’s 80-3200, yet real-world high ISO usability is constrained by noise in both. The Sigma’s larger sensor endows superior noise control, enabling better low-light performance, while Sony’s smaller sensor creates evident noise at ISO above 400.
