Choosing the right camera in today's diverse market often means balancing convenience, image quality, and specific photographic needs. Whether you are a beginner stepping up from a smartphone or a seasoned enthusiast hunting for a compact travel buddy or an entry-level DSLR, understanding how these cameras perform in the real world is crucial. I’ve spent extensive time testing the Panasonic Lumix DMC-FH20 - a compact point-and-shoot from Panasonic’s 2010 lineup - against the even older but still relevant Sony Alpha DSLR-A390, an entry-level DSLR aimed at photography learners. This comparison draws on hands-on experience and technical evaluation to shed light on what each camera brings to the table in 2024.

The Body and Ergonomics You’ll Actually Use: Compact Convenience vs DSLR Presence

Before diving into specs and image quality, let’s look at how these cameras feel and fit in your hand - a foundational part of any photographic experience.

The Panasonic FH20 is a compact powerhouse weighing only 178 grams with dimensions of 100 x 56 x 28 mm, making it pocketable and very travel-friendly. Its fixed lens and straightforward rectangular design make it a true grab-and-go solution ideal for casual outings or brief photoshoots when you want minimal fuss.

By contrast, the Sony A390 is a more substantial 549 grams with a bulkier body of 128 x 97 x 86 mm. Its DSLR form factor means you can expect a more pronounced grip, physical dials, and buttons that facilitate manual adjustments. This heft translates to steadier handling during longer shoots or when paired with larger lenses.

The Panasonic benefits from a slim, no-frills design but lacks dedicated manual controls, which some photographers may find limiting. The Sony sports a more traditional top-plate arrangement, offering dedicated exposure controls that I appreciated in more deliberate shooting scenarios.

Summary:

• FH20: Ultra-portable, simple design, ideal for casual travel and everyday snapshots.
• A390: Larger but ergonomically comfortable for extended use with better manual control access.

User Interface and Control Layout: Navigating Your Creative Workflow

The Panasonic’s rear sports a fixed 2.7-inch LCD screen without touchscreen capabilities or an electronic viewfinder. Its user interface is intuitive but minimal, relying on menu navigation rather than quick-access buttons.

The Sony features a similarly sized 2.7-inch tilting LCD, allowing flexible composition from difficult angles - a welcome addition even if resolution matches the Panasonic’s modest 230k dots. More importantly, the A390 includes an optical pentamirror viewfinder with 95% frame coverage and 0.49x magnification. For those who prefer composing via an eyepiece, this is invaluable, especially in bright daylight.

During prolonged testing, I found the Sony’s physical dials for shutter, aperture, and exposure compensation far more efficient for creative shooting. The Panasonic, intended for point-and-shoot convenience, does not cater well to in-depth exposure adjustment or quick menu toggling, potentially frustrating advanced photographers.

Summary:

• FH20: Fixed LCD, simple menus, limited direct control - great for beginners or casual use.
• A390: Tilting LCD plus optical viewfinder, extensive physical controls, faster manual adjustments.

Sensor Technology and Image Quality: Size, Resolution, and Real-World Output

At the heart of any camera is its sensor - influencing detail, dynamic range, and low-light performance.

The Panasonic FH20 uses a 1/2.3-inch CCD sensor, measuring 6.08 x 4.56 mm with a total area of just 27.72 mm², outputting 14 megapixels at 4320x3240 resolution. As with most small sensor compacts, this translates to limited light gathering capability, resulting in noticeable noise above ISO 400 and less dynamic range, especially in shadows or highlights.

The Sony A390 sports a significantly larger APS-C CCD sensor (23.5 x 15.7 mm), 368.95 mm² area, also delivering 14 MP (4592x3056 pixels). The bigger sensor size means improved image quality, especially in low light and better tonal gradation. Sony’s CCD sensor here is known for solid color rendition and decent dynamic range for its era.

Real-world testing:

• Dynamic range: Sony notably preserves detail in shadows and highlights better than Panasonic, thanks to sensor size and better analog-to-digital conversion.
• ISO performance: Panasonic’s FH20 starts showing visible noise beyond ISO 200; Sony A390 handles ISO 800 well and usable results up to ISO 1600.
• Color and detail: Images from the Sony demonstrate richer colors and discernible detail on fine textures such as foliage or fabric - critical for landscape and portrait work.

Consider the sensor size multiplier effect too: Panasonic’s 8x zoom range on a tiny sensor means less flexibility with depth of field and bokeh control, compared to Sony’s 1.5x crop factor DSLR format compatible with dozens of lenses.

Summary:

• FH20: Small sensor restricts image quality for professional or large print use.
• A390: Larger APS-C sensor yields higher quality images, better ISO performance, and dynamic range.

Autofocus System Deep Dive: Accuracy, Speed, and Practical Shooting

Autofocus speed and precision significantly impact your ability to capture decisive moments, especially in action or wildlife photography.

The Panasonic has a contrast-detection AF system with 9 focus points but no face or eye detection. It supports only single AF mode, no continuous tracking, meaning you must half-press to focus and then time your shot carefully. The AF system is slow compared to modern standards, occasionally hunting in lower light or high-contrast situations.

Sony’s A390 features a phase-detection AF system with 9 focus points as well but supports continuous AF tracking, face detection in live view, and selective AF area modes. This setup is considerably more robust, with tracking AF helping with moving subjects during sports or wildlife shoots.

In practical use:

• Panasonic is sufficient for static and casual photos but struggles with moving subjects.
• Sony delivers reliable focus locking and better tracking, though still limited by entry-level timing.

Summary:

• FH20: Basic AF suitable for still subjects only, moderate speed and accuracy.
• A390: More capable AF with tracking and face detection, better suited for action and portraits.

Lens Ecosystem and Versatility: Fixed Zoom vs. Expandable System

One fundamental difference here is Panasonic’s FH20 is a fixed-lens compact with a built-in 28-224mm (35mm equivalent) f/3.3–5.9 zoom lens. This convenience is great for simplicity but offers no upgrade path or specialized optics.

The Sony A390 uses the Sony/Minolta Alpha mount, compatible with over 140 lenses spanning primes, zooms, macro, telephoto, and specialty optics. This expansive ecosystem dramatically increases versatility whether you focus on portraits, landscapes, or wildlife.

Notable points:

• The Panasonic’s 8x zoom can cover many casual scenes but loses performance in low light due to narrow aperture.
• Sony’s mount allows faster lenses (f/1.4, f/2.8) and long telephoto lenses for challenging subjects (sports/wildlife).
• Adaptors can even allow legacy lenses for vintage optics enthusiasts.

For anyone seriously aiming to grow their kit and skills, Sony’s system is far more future-proof.

Summary:

• FH20: Fixed lens optimized for walk-around shooting, no upgrade path.
• A390: Broad lens compatibility supports creative growth across genres.

Burst Shooting, Shutter Speeds, and Exposure Controls: Timing Is Everything

For sports or wildlife enthusiasts, the ability to shoot bursts and capture fast action is crucial.

• Panasonic FH20 offers 5 frames per second (fps) continuous shooting, but without autofocus tracking, so sharpness can be hit or miss.
• Sony A390 yields about 3 fps burst rate, slower but with continuous AF enabling better focus on moving subjects.

Shutter speed range differs as well:

• FH20 max shutter speed maxes at 1/1600 sec, and minimum is 60 sec in bulb mode.
• Sony A390 maxes out at 1/4000 sec, providing more flexibility for fast action and wide aperture use in daylight.

The A390 supports manual, aperture, shutter priority, and exposure compensation modes, enabling fine control over exposure creative decisions. The FH20 has none of these advanced exposure modes - an important limitation for enthusiasts.

Summary:

• FH20: Faster burst rate but limited exposure controls and slower shutter ceiling.
• A390: Slower burst with continuous AF and full manual exposure options.

Video Capability: Modest HD vs. No Video Functionality

Panasonic FH20 supports video recording up to 1280 x 720 (HD) at 30fps using Motion JPEG codec. It’s basic but usable for casual video clips. No mic or headphone ports limit audio control.

The Sony A390, designed as a DSLR for stills, does not support video recording. This absence reflects the DSLR era before video shooting became standard in cameras.

If you’re interested in casual video with your still camera, Panasonic’s FH20 offers entry-level options - albeit limited in codec and stabilization - whereas Sony A390 won’t serve you if video is a priority.

Battery Life and Connectivity: Longevity Counts

Sony A390 uses a proprietary NP-FH50 battery, rated for approximately 230 shots per charge - typical for entry-level DSLRs. It supports USB 2.0 and HDMI output, allowing image transfer and tethered shooting or viewing on TVs.

Panasonic FH20’s battery life is unspecified but compact cameras generally offer modest durations due to smaller batteries. It supports USB 2.0 but lacks any wired or wireless connectivity like Wi-Fi, Bluetooth, or GPS on either model.

Neither camera features wireless connectivity, reflecting their era, so transferring images on the go requires card readers or cables.

Durability and Environmental Sealing: How Tough Are These Cameras?

Neither camera offers environmental sealing, waterproofing, dustproofing, or freeze-proofing. Given Panasonic’s compact build, it is less robust physically, while the Sony’s DSLR chassis is more rugged but not weather-sealed.

For outdoor photography, especially in adverse conditions, neither camera stands out, though the Sony’s DSLR body generally withstands bumps better due to heavier construction.
