Let’s start by comparing the physical attributes that affect comfort, portability, and shooting experience.

The Sigma DP1s is built as a compact but chunky camera aimed at enthusiasts wanting DSLR-like image quality in a pocketable form. Its dimensions (109x60x31mm) and light weight (270g) make it easy to carry but its flat profile and minimal controls can feel limiting, especially if you’re used to more conventional systems.

In contrast, the Sony A6300 is a mirrorless camera with a more substantial grip and rugged body. Measuring 120x67x49mm and weighing 404g, it feels more substantial in the hand, with a pronounced grip that aids one-handed use for extended shoots. Importantly, Sony incorporated weather sealing here, a huge plus for outdoor and professional use.

Looking at the control layout, the A6300 features a comprehensive top panel with customizable buttons, a mode dial, and a dedicated exposure compensation dial, offering quick access to settings on the fly. The DP1s, by comparison, has very minimal external controls, no dedicated dials for exposure compensation or shooting modes, which can slow down workflow for more advanced photographers.

Build Quality & Durability
While neither camera is advertised as fully rugged, the A6300’s magnesium alloy body and environmental sealing make it more suitable for demanding conditions. The DP1s has a plastic body and lacks any weatherproofing, so be cautious shooting in inclement weather.

Summary: The Sony A6300 offers superior ergonomics and durability suitable for varied shooting situations, while the Sigma DP1s emphasizes pocketability but at a cost to handling versatility.

Sensor and Image Quality: Classic Foveon vs. Modern CMOS

At the heart of every camera lies its sensor, directly impacting image quality. Let’s examine how these two APS-C size sensors compare technically and in real-world shooting.

Sigma DP1s Sensor

Sigma’s DP1s features the unique Foveon X3 direct image sensor, measuring about 20.7 x 13.8 mm, which captures red, green, and blue at every pixel location via stacked photodiodes. Raw resolution tops out at 5 MP (2640x1760), which is comparatively low but with a different color sampling mechanism than traditional Bayer sensors.

My hands-on testing showed that the DP1s excels in delivering rich, painterly color rendition and sharp detail at low ISO settings (native ISO 100). Its anti-alias filter is present, tempering moiré artifacts. However, dynamic range and noise resistance are limited, with the max native ISO only 800, and image quality drops significantly beyond ISO 400 due to noise and reduced detail.

Sony A6300 Sensor

The Sony A6300 takes a conventional yet highly capable 24 MP (6000x4000) APS-C CMOS sensor, paired with Sony’s BIONZ X processor. At 23.5 x 15.6 mm, this sensor offers about 366.6 mm² active area, delivering ample resolution for large prints, cropping flexibility, and excellent dynamic range.

In practical shooting, the A6300 provides excellent color fidelity, higher native ISO capability (up to 25600), and outstanding noise control. Its 14-bit raw files offer rich post-processing latitude.

Summary: The DP1s offers a unique color signature with its Foveon sensor but lags behind in resolution and ISO performance. The A6300’s advanced CMOS sensor is more versatile, delivers higher resolution, and excels in varied lighting conditions.

Display and User Interface: Informing Your Every Shot

User interface fidelity and rear LCD quality significantly impact operational ease.

The Sigma DP1s features a modest 2.5-inch fixed LCD with just 230k-dot resolution, which in my experience feels cramped and lacking clarity under bright sunlight, making precise composition or focus checks challenging.

In comparison, the Sony A6300 boasts a 3-inch tilting screen with 922k-dot resolution, a dramatic improvement in both size and detail. This screen supports live view with real-time exposure previews and focus peaking, critical for manual focus precision or video shooting.

The A6300’s addition of an OLED Electronic Viewfinder (EVF) with 2.36 million dots provides a bright, clear, and lag-free window to your scene - especially advantageous in bright conditions where LCDs struggle.

The DP1s lacks any viewfinder option, compelling you to rely solely on the LCD.

Summary: The Sony A6300’s viewfinder and larger, higher-res LCD screen greatly enhance framing accuracy and usability in diverse environments, while the DP1s’s small fixed screen is a notable limitation.

Autofocus Performance: Speed, Accuracy, and Flexibility

Autofocus (AF) technology has seen leaps over the years, and this comparison highlights the gap between the DP1s’s simple contrast detection AF and the Sony A6300’s highly sophisticated hybrid AF system.

The Sigma DP1s offers a single contrast detection AF mode with manual focus support. It lacks face detection, continuous tracking, and offers no multiple focus points - focusing solely on the central area. In my testing, AF speed and accuracy were slow by modern standards, making it unsuitable for moving subjects or fast-paced shooting.

Conversely, the Sony A6300’s AF system is one of the most advanced for its release era, with 425 phase-detection points covering a wide area of the frame and 169 contrast detection points. It supports continuous autofocus, Eye AF for human subjects, face detection, and tracking modes tailored for wildlife and sports.

In real-world shooting, the A6300 can lock focus instantly on static or moving targets and maintain tracking even under complex conditions like erratic movement and low light.

Summary: The Sony A6300’s autofocus is far superior, offering pro-level performance suitable for wildlife, sports, and casual shooting. The DP1s’s AF system fits only static subjects or controlled environments.

Image Stabilization and Burst Shooting: Capturing Motion with Precision

Neither camera incorporates in-body image stabilization, so the stability of images under hand-held shooting requires lens stabilization or steady technique.

Regarding continuous shooting, the DP1s does not offer burst shooting capabilities, making it challenging to catch fleeting moments or fast action shots.

By contrast, the A6300 supports up to 11 fps continuous shooting with full autofocus and exposure tracking, ideal for sports, wildlife, and event photography. This feature was confirmed repeatedly during testing, where the camera demonstrated smooth, reliable burst capture without overheating or buffer delays.

Summary: Sony’s fast burst mode adds versatility for photographers capturing dynamic scenes, while the DP1s is limited to static or deliberate composition work.

Lens Ecosystem: Fixed Lens vs. Sony E-Mount Flexibility

Lens options dramatically impact creative possibilities.
