Panasonic LZ20 vs Sony H55: A Hands-On Comparison of Two Small Sensor Superzooms

Choosing the right camera can be a tricky puzzle, especially when cameras appear similar in category but target slightly different users. Today, I’m putting two small sensor superzoom cameras head-to-head: the Panasonic Lumix DMC-LZ20 (LZ20) and the Sony Cyber-shot DSC-H55 (H55). Both hail from the early 2010s and promise easy handling with versatile zoom ranges. However, beneath the surface, there are meaningful differences that impact real-world photography across many genres.

Drawing from years of hands-on testing and direct comparisons, I’ll unpack how these two cameras stack up in image quality, autofocus performance, usability, and more. My goal is to help you decide which model - if either - suits your photography style and budget.

First Impressions: Size, Build, and Handling

Let’s start with the basics: what it feels like to pick up and shoot with each camera.

• Panasonic LZ20 sports a classic SLR-like bridge camera body, measuring 120 x 76 x 80 mm and weighing about 499 g with battery.
• Sony H55 is a more compact point-and-shoot style, at 103 x 58 x 29 mm and just 200 g.

In practical terms, the LZ20 feels more substantial and grippy in hand, with a deep thumb rest and textured grip. This bulkier design appeals to those who favor stability, especially at long focal lengths. The extra heft reduces camera shake in telephoto shooting - a crucial factor when your lens reaches 525 mm equivalent.

The H55, however, excels in portability. It slips easily into a jacket pocket or small bag, suiting travel or street photography where discretion matters. Its slim profile is comfortable for on-the-go snapshots, though shooting at full zoom might feel less stable compared to the Panasonic.

Top control layouts reveal more of their intended use cases.

The LZ20 offers fewer dedicated dials and no thumb joystick, opting for simplicity over pro-level controls. The Sony H55 showcases fewer buttons overall but compensates with an intelligent Bionz processor behind the scenes for automatic optimizations.

Summary:

Recommendation:
Choose LZ20 for comfort with longer lenses and handheld shooting. Pick H55 if you prioritize size and portability.

Sensor and Image Quality – Under the Hood

Sensor specs and imaging pipelines fundamentally shape image quality. Both cameras feature a 1/2.3" CCD sensor - a common small sensor size in bridge and compact cameras - but resolution and processing differ.

While the LZ20 edges out slightly in resolution, the Sony’s Bionz image processor sometimes handles noise better at base ISOs. However, expect limited dynamic range and noise performance typical of small 1/2.3" sensors. Neither supports raw, limiting post-processing latitude.

Practically, for well-lit conditions, both produce adequately sharp photos with decent color. At higher ISOs (beyond 400-800), image noise becomes easily visible and reduces fine detail.

Landscape shooters relying on big prints or heavy cropping may find both cameras lacking, due to sensor constraints and absence of raw files. However, during my testing, the Panasonic’s higher resolution did help preserve detail slightly better in bright daylight.

The Sony’s max ISO topping at 3200 native, compared to the Panasonic’s 1600 native, didn’t translate to noticeably better low-light shots - it’s more a marketing spec than practical advantage given small sensor noise profiles.

Summary:

Autofocus and Shooting Performance: Speed and Accuracy

Autofocus (AF) can make or break your experience, especially in fast-moving scenarios like wildlife or sports.

• Panasonic LZ20 offers contrast-detect AF with 9 focus points. It supports face detection but no continuous tracking or animal eye AF.
• Sony H55 uses a similar contrast-detection system, also with 9 points, but only offers single AF with no continuous AF or face detection.

The contrast-detection system, common in compact cameras, is generally slower and less accurate than phase-detection AF found in DSLRs or mirrorless systems I’ve tested extensively.

During real-world sessions:

• The LZ20’s AF was a little sluggish, especially when zoomed in at 525 mm equivalent. It sometimes hunted briefly before locking focus on small or low-contrast subjects.
• The H55's AF was generally faster in bright light due to efficient processor-assisted algorithms, but struggled with moving subjects and rarely refocused quickly.

Continuous high-speed shooting is an important factor for wildlife and sports shooters.

The H55’s 10 fps burst is impressive on paper for this class, but limited buffer and slow AF mean it’s mostly good for short, decisive bursts in static or slow action scenes.

The Panasonic’s single fps continuous is slow but more consistent for deliberate shooting.

Summary:

My takeaway:
For portraits or precise focusing, Panasonic LZ20 wins with face detection. For casual sports or wildlife snapshots, Sony H55’s fast burst speed may capture decisive moments better, but you lose accuracy.

Build Quality and Weather Sealing

Neither camera includes weather sealing, waterproofing, or ruggedization. These are entry-level consumer models after all, designed primarily for casual photography.

Build feels solid on the LZ20, reflecting its bridge camera heritage, with well-fitted plastic and metal components. The H55’s compact plastic shell is lighter but less robust.

Ergonomics and User Interface

Both cameras have fixed, non-touch 3” LCD screens but differ in resolution and clarity.

• LZ20 screen: 460k dots, offering crisp detail for composing and reviewing images.
• H55 screen: 230k dots, more basic and prone to glare in bright sunlight.

Neither features a viewfinder, so you’re shooting entirely from the rear LCD.

Menus on both models are straightforward but limited in customization. The Panasonic allows manual exposure modes and exposure compensation; the Sony locks you out of manual exposure, sticking to program modes.

This difference is vital for enthusiasts who want creative control.

Lens Range and Optical Performance: Zoom That Counts

Superzoom capability is a key selling point here.

The LZ20’s massive 21x zoom is a huge advantage for wildlife or distant subjects. I found the lens produced reasonably sharp images up to about 300 mm equivalents; beyond that, image quality softening and chromatic aberration creep in. Still, reaching 525 mm in a compact package remains remarkable.

The Sony’s 10x zoom covers 25-250 mm, more modest but sufficient for general photography.

Both lenses incorporate optical image stabilization (OIS), crucial when shooting telephoto. Panasonic’s OIS worked very well in my tests, reducing camera shake noticeably even at long zoom lengths, making handheld shooting achievable without tripod support.

Sony’s stabilization is good but slightly less effective at maximum zoom.
