When it comes to selecting your next camera, the challenge often lies in balancing needs, budget, and intended use. Today, I’ll take you through an in-depth comparison of two intriguing models from the last decade: Panasonic's compact Lumix FH7 and Sony's entry-level DSLR Alpha A550. Though ostensibly targeted at quite different segments, evaluating these cameras side by side offers valuable lessons in sensor size, usability, image quality, and versatility.

I’ve spent hours shooting with each, putting them through typical routines from portraits to landscapes, wildlife, street photography, and more - assessing everything from autofocus speed to ergonomic feel. Whether you’re a casual snapshooter or an enthusiast aiming for a capable backup camera, this comparison will help you understand the trade-offs and determine which setup suits your style.

Let’s dive into the nitty-gritty.

Size, Build & Handling: Compact Convenience versus DSLR Presence

At first glance, these two couldn't be more different on the outside. The Panasonic FH7 is a true pocket-friendly compact, weighing only 126 grams and measuring just 95x56x19 mm. In contrast, the Sony A550 tips the scales at a hefty 632 grams, with dimensions of 137x104x84 mm - nearly five times heavier in weight.

Holding the FH7, you immediately notice how lightweight and minimal it feels. It’s designed for grab-and-go convenience, slipping easily into a jacket pocket or small purse. The fixed lens and minimal physical controls make operation straightforward but limited. Its compactness appeals most to casual shooters who prioritize portability above all.

Meanwhile, the A550 has that classic DSLR heft and grip, lending confidence when handholding lenses, especially telephoto ones critical for wildlife or sports. The larger body accommodates extensive buttons and dials - a boon for those who prefer manual control and quick access. The pentamirror optical viewfinder offers a clear shooting window, unlike the FH7’s lack of any viewfinder, relying solely on the rear LCD.

Speaking of controls, look at the top panel:

Sony’s dedicated mode dial, exposure compensation button, and multiple customizable controls create an intuitive layout for photographers accustomed to more hands-on shooting. Panasonic’s FH7, with its simplified scheme, targets beginners or casual users who want a point-and-shoot experience.

Ultimately, if you value pocketability and simplicity, the FH7 wins hands down. If comfortable ergonomics and manual exposure control are your priorities, the A550 earns the nod.

Sensor and Image Quality: The Heart of the Matter

The fundamental difference that shapes image quality here is sensor size and type:

• Panasonic FH7: 1/2.3" CCD sensor measuring 6.08 x 4.56 mm (~27.7 mm²), with 16MP resolution.
• Sony A550: APS-C sized CMOS sensor measuring 23.4 x 15.6 mm (~365 mm²), with 14MP resolution.

The larger APS-C sensor of the A550 dwarfs the tiny compact sensor of the FH7. This size advantage translates into superior dynamic range, better low-light capability, and less noise at high ISOs. The Sony’s sensor offers an overall DxOmark-like score around 66 (unofficially), with 21.9 bits color depth and 11.8 stops dynamic range - excellent for its class. The FH7 lacks official sensor tests but, given its format, its dynamic range and low-light performance are understandably limited.

In my practical tests, the A550 produced cameras with rich tonal gradations and more detail retention in shadows and highlights. The FH7’s compressed dynamic range is evident in challenging lighting, where highlights clip quickly and shadows lose detail.

Color depth and ISO performance also favor Sony’s CMOS sensor. The FH7’s max native ISO of 6400 is theoretically higher, but image quality deteriorates faster due to sensor noise. Sony’s 12800 ISO ceiling is more usable, especially in moderate low-light conditions.

This gap directly impacts:

• Portraits: Sony captures skin tones with better nuance and smoother gradients; Panasonic sometimes produces flat or slightly washed-out results.
• Night or Astro Photography: Sony’s low-light prowess enables cleaner images with longer exposures.
• Landscape: Dynamic range noticeably benefits the Sony, preserving highlight detail on bright skies.

The resolution difference is minimal: both hover around 14-16MP, but the larger sensor with better pixel pitch on the A550 yields more usable detail.

LCD and Viewfinder: Your Window to the World

With no optical viewfinder, Panasonic FH7 relies entirely on the 3-inch fixed, touchscreen LCD (230k dots). It’s serviceable for framing in bright conditions but struggles under sunlight and offers limited resolution.

Sony’s 3-inch tilting LCD offers more than 900k dots, delivering sharp preview images and flexible angles, ideal for high or low shooting positions common in macro or street photography.

Additionally, the A550’s pentamirror optical viewfinder (95% coverage) provides a natural framing experience and is invaluable in bright light or action shooting, where lag-free feedback counts.

If composing through a viewfinder is critical to your shooting style, the Sony easily outperforms the FH7's absence of one.

Autofocus and Shooting Speed: Tracking the Moment

Performance here is split dramatically by targeting different user bases.

Panasonic FH7 offers contrast-detection AF with 11 focus points and face detection. It supports touch AF and limited AF tracking, but does not offer continuous AF or manual focus. Its burst rate maxes out at a modest 4 fps, sufficient for casual snapshots but not demanding sequences.

Sony A550 features a hybrid AF system combining 9-point phase-detection with contrast detection for fast, accurate focusing. It supports single, continuous, and manual focus modes, and shoots at 7 fps - a respectable speed for an entry DSLR in 2009.

In practical testing:

• Wildlife and Sports: Sony’s AF locks quickly on moving subjects, with less hunting, and sustains continuous tracking reasonably well for amateurs. The FH7 struggles with tracking fast action and slower focus response.
• Portraits: Both perform well given still subjects, but Sony’s higher precision AF contributes to sharper eyes in portraits.
• Low light: Sony’s phase-detection AF outperforms Panasonic’s contrast-only system, which hunts noticeably as light dims.

When capturing fleeting moments or moving subjects, Sony’s faster AF and frame rate strongly advantage advanced amateurs.

Lens Options and Focal Range

A critical distinction exists between fixed lens and interchangeable lens systems.

• Panasonic FH7 has a built-in 28-112mm equivalent (4x zoom) with an aperture range of f/3.1 to f/6.5. It’s versatile for general-use snapshots and mildly zoomed images but cannot be changed or upgraded.

• Sony A550, with its Minolta Alpha mount, supports over 140 compatible lenses, including fast primes, macro, telephoto zooms, and third-party options. This extensive ecosystem empowers photographers to tailor their kit precisely.

In genres like wildlife, sports, or macro, where specialized lenses make a difference, Sony’s system clearly dominates.

Durability and Weather Resistance

Neither camera boasts environmental sealing or ruggedness. Both should be treated carefully, away from rain or dusty conditions. However, Sony’s DSLR build quality feels sturdier and more substantial, translating to longer professional use without discomfort or worry about fragility.

Battery Life and Storage Convenience

Sony A550 leverages the NP-FM500H battery, rated for approximately 480 shots per charge, nearly double Panasonic FH7’s 260 shots. This becomes significant in extended shoots or travel, where extra batteries might not be easily accessible.

Storage-wise, both accept SD cards; Sony additionally supports Memory Stick formats, a legacy consideration. Neither supports dual slots - something to keep in mind if battery or storage backup is crucial to you.

Connectivity and Accessories

Connectivity is sparse by modern standards in both models - no Wi-Fi, Bluetooth, NFC, or GPS. USB 2.0 is standard; Sony includes an HDMI port for direct output, useful for tethered shooting or playback on large displays.

Sony’s support for external flashes and advanced flash modes expands creative capability. Panasonic FH7 limits you to a built-in flash, with no hotshoe for external units.
