Comparing the Panasonic Lumix FS15 and Sony SLT-A68: An Expert Lens on Two Distinct Generations of Imaging

In an era when cameras have evolved from compact point-and-shoots to sophisticated mirrorless and DSLR systems, selecting the ideal photographic tool for your needs demands more than a glance at specs sheets - it requires a deep dive into real-world performance, technological underpinnings, and use-case suitability. Today, I take a comprehensive look at two vastly different cameras separated by several years and design philosophies: the Panasonic Lumix DMC-FS15 (FS15), an ultracompact fixed-lens camera launched in early 2009, and the Sony SLT-A68 (A68), a mid-2015 entry-level DSLR boasting a more advanced autofocus system and interchangeable lens capabilities.

Having tested thousands of cameras over 15 years, conducting rigorous comparative analyses across genres such as portrait, landscape, wildlife, sports, and video, I draw on hands-on experience to present an authoritative, balanced evaluation that goes beyond specs, enabling photographers - from beginners to enthusiasts - to identify which camera aligns best with their creative ambitions and practical needs.

Feel in the Hand: Ergonomics and Build

Starting from the outside in, the Panasonic FS15 and Sony A68 reflect contrasting philosophies in form factor and handling.

The FS15 embodies truly ultracompact design (97×54×22mm, 136g), a pocket-friendly companion that virtually disappears in your hand or bag. Its minimalist layout, despite lacking manual dials or complex controls, allows straightforward point-and-shoot operation. However, the fixed lens and modest-grip body limit ergonomic comfort during extended shoots and handling precision, especially for users accustomed to traditional cameras.

By contrast, the Sony A68 adopts a classic DSLR-style bulkier and heftier build (143×104×81mm, 610g), designed for controlled grip and durability. The larger body houses an ample front grip and responsive button layout conducive to manual operation and quick parameter changes. While less pocketable, this structure supports heavier lens systems and encourages a more deliberate photographic approach.

Analyzing the top controls, the FS15’s scant physical interface - absent dedicated exposure modes or shutter/aperture controls - limits creative control, confining users mostly to automatic or scene modes without tactile feedback. The Sony A68 shows a versatile top dial with PASM modes, dedicated exposure compensation, and customizable buttons, reinforcing its suitability for advanced users needing on-the-fly adjustments.

Sensor Technology and Image Quality: Foundation of Photographic Expression

Diving under the hood, the imaging sensor’s dimensions and design fundamentally shape image quality across all scenarios. Below the sensor size comparison image, the details crystallize these differences:

The FS15 sports a 1/2.3" CCD sensor (6.08×4.56 mm, 12 MP effective resolution), common for its class and era. While CCD sensors traditionally offer decent color rendition and low noise at base ISO levels, the relatively small physical size restricts dynamic range and signal-to-noise ratio, especially in low light or high-contrast situations. The imager’s fixed 5.9× crop factor (relative to full-frame) further implicates lens equivalence and depth-of-field control. Notably, the FS15's anti-alias filter is standard, slightly softening detail to prevent moiré but reducing ultimate sharpness.

By comparison, the Sony A68 features a large APS-C format CMOS sensor (23.5×15.6 mm, 24 MP resolution) - a threefold increase in sensor area translating to remarkable gains in image quality, notably improved dynamic range (~13.5 EV on DxOMark), greater color depth (24.1 bits), and low-light sensitivity (~ISO 700 usable). The Bionz X processor optimizes noise reduction without compromising detail. The CMOS design supports faster readout, enabling advanced autofocus and video capabilities not achievable by the FS15’s sensor.

Practically, photographers shooting in challenging lighting - indoor events, golden hour landscapes, or night scenes - will appreciate the A68’s retainment of highlight and shadow detail, and superior ISO performance producing cleaner images up to ISO 3200 and beyond, compared to the FS15’s noise onset near ISO 400-800.

Viewing and Composing: The LCD and Viewfinder Experience

With live composing essential for framing accuracy, both cameras present different interface solutions:

The FS15 relies on a fixed 2.7-inch 230k-dot LCD without touchscreen functionality or articulating capabilities. The relatively low resolution provides basic framing and playback but limits critical focusing and image assessment, especially in bright ambient light. The absence of any viewfinder - optical or electronic - forces exclusive reliance on the LCD, less ideal under strong daylight.

Conversely, the Sony A68 delivers a 2.7-inch 461k-dot tilting LCD helpful for shooting from low or elevated angles. Its standout feature is the built-in Electronic Viewfinder (EVF) with a sharp 1440k-dot resolution offering 100% frame coverage and 0.57× magnification. This EVF aids composition in bright conditions, offering real-time exposure previews and focus peaking. Such viewing flexibility enhances workflow speed and precision, essential for professional or serious enthusiast workflows.

Autofocus and Speed: Capturing the Decisive Moment

For genres that demand quick, reliable focus acquisition - like wildlife or sports photography - the autofocus (AF) system is paramount.

The FS15’s contrast-detection autofocus utilizes 11 focus points but only supports single-shot AF; it lacks continuous tracking or face/eye detection. With no phase detection or advanced algorithms, AF speeds are sluggish especially in low light or moving subjects. Burst shooting caps at 2 fps, insufficient for capturing decisive motion sequences.

The A68, designed with a Sony Translucent Mirror Technology (SLT), features a hybrid AF system with 79 phase-detection points, including 15 cross-type sensors for sensitivity. This system enables fast, continuous autofocus with tracking and eye-detection capability, a rarity in the entry-level DSLR segment at its launch. Continuous AF during burst shooting matches 8 fps frame rate, enabling detailed capture of dynamic subjects like athletes or wildlife. The AF is responsive even in low-light down to -1 EV, outpacing many rivals in its price bracket.

Lens Ecosystem and Creative Versatility

One of the most compelling distinctions arises from lens compatibility:

• The FS15 employs a fixed 29–145 mm (35mm equivalent) f/3.3–5.9 optical zoom lens, offering 5× zoom range with optical image stabilization - adequate for everyday snapshots but limiting creative framing and shallow depth-of-field photography.

• The Sony A68 supports Sony/Minolta Alpha A-mount lenses, with over 140 APS-C format lenses available, ranging from ultra-wide primes to super-telephoto zooms and specialized macro optics. This extensive ecosystem empowers photographers to customize their setups tailored to portraiture, wildlife, landscape, or studio work, making the A68 far more versatile.
