Panasonic ZS40 vs Sony NEX-5: A Hands-On Comparison from a Seasoned Camera Reviewer

Choosing between two distinctly different cameras such as the Panasonic Lumix DMC-ZS40 (a compact superzoom) and the Sony Alpha NEX-5 (an entry-level mirrorless) requires more than just scanning specs sheets. From my 15+ years of testing cameras across all photographic genres, I’ve developed a methodology that combines technical analysis, field tests, user experience, and value assessment. This detailed comparison will help you decide which camera suits your shooting style and expectations best.

What’s on the Table: Compact Superzoom vs Mirrorless Starter

Before diving into the nitty-gritty, here’s a quick overview:

• Panasonic ZS40: A highly pocketable compact camera that boasts a massive 30x zoom (24-720mm equivalent) and built-in GPS. Its strength lies in versatility, travel convenience, and an all-in-one package for casual to enthusiastic photographers who want reach without lugging heavy lenses.

• Sony NEX-5: A pioneering mirrorless model debuting in 2010, featuring an APS-C sensor, interchangeable Sony E-mount lenses, and an accessible rangefinder-style body. Though not the newest player by any means, its larger sensor and lens ecosystem offer tangible image quality and creative control advantages.

Both cameras aim at different segments of photography enthusiasts, so the devil is in the details.

Handling and Ergonomics: Comfort Meets Control

Ergonomics dictate how long and comfortably you can shoot, especially in fast-paced or extended sessions. I spent considerable hours manually operating both cameras to understand their physical handling traits.

Panasonic ZS40

• Compact and ultra-light at just 240g with dimensions of 111x64x34mm.
• The grip is modest but secure given its size.
• Fixed lens means no lens changes - a plus for casual shooting.
• Single 3” non-touch TFT LCD with a modest 920k-dot resolution.
• An electronic viewfinder (EVF) is present but limited at 200k dots.
• Controls are basic; no fully customizable buttons or illuminated controls.

Sony NEX-5

• Slightly larger and heavier at 287g (111x59x38mm), but more robust feel.
• Rangefinder-style body gives better grip and balance, especially with larger lenses.
• Interchangeable lenses drastically expand creative potential.
• Tilting 3” LCD with the same 920k-dot resolution.
• No built-in EVF - a factor some users may find limiting.
• More physical controls, albeit non-illuminated.

My Take: If you prioritize pocketability and straightforward handling, ZS40 wins here. But for those who want more physical control and are willing to trade compactness for better handling, the NEX-5 offers more comfort with lenses attached.

Sensor Technology and Image Quality: Size Does Matter

At the heart of image quality is the sensor. Let’s dissect the Panasonic’s 1/2.3” 18MP CMOS sensor versus Sony’s APS-C 14MP CMOS sensor.

Panasonic ZS40 Sensor

• Tiny 1/2.3” sensor measuring just 6.17 x 4.55 mm.
• 18-megapixel resolution, suitable for casual prints and screen sharing.
• Sensor size limits dynamic range and low-light performance.

Sony NEX-5 Sensor

• APS-C sensor significantly larger at 23.4 x 15.6 mm.
• 14MP, which provides excellent pixel pitch aiding high image quality.
• Offers superior noise handling, tonal gradation, and better dynamic range.
• Supported by high DxOMark scores: 69 overall, notable for color depth (22.2 bits) and dynamic range (12.2 EV).

Real-World Impact: During my controlled test shoots, especially in challenging light, the Sony NEX-5 produced cleaner files, richer colors, and far better highlight/shadow retention. The Panasonic struggles at ISO above 800, while the NEX-5’s native ISO extends comfortably to 3200 and beyond.

Autofocus Systems: Speed, Accuracy & Tracking

Reliable autofocus (AF) can make or break decisive moments, from wildlife to street snaps.

Panasonic ZS40 AF

• Contrast-detection AF with 23 focus points.
• Face detection included, but no continuous eye detection.
• Offers tracking and continuous AF modes.
• No phase-detection pixels.

Sony NEX-5 AF

• Also contrast-detect only with 25 focus points.
• No eye detection or face tracking in the classic sense.
• No continuous tracking AF.
• No phase-detection autofocus.

Testing Notes: Both cameras lack the sophisticated hybrid or on-sensor phase detection systems found in newer models. The Panasonic’s AF felt snappier at distant zoom lengths - no surprise given its focus on superzoom optics. The NEX-5 performs well with prime lenses but can slow down in low light or during continuous AF in sports.

Lens Flexibility and Ecosystem

Lens choice fundamentally affects how versatile a camera can be.

• Panasonic ZS40: Fixed lens only - a 24-720mm (30x optical zoom) F3.3-6.4 lens with optical image stabilization optimized for versatility but limited in optical quality and aperture.

• Sony NEX-5: Sony E-mount with 121 lenses available (from primes to zooms, macro, and specialty lenses). Focal lengths and apertures vary widely. You can use fast f/1.8 primes for portraits and bright conditions or telephoto zooms for wildlife and sports.

Summary: The NEX-5 offers significantly more creative freedom through glass options, which is a major plus for enthusiasts willing to invest in lens upgrades over time.

Build Quality and Weather Protection

Neither camera is explicitly weather-sealed. Both are vulnerable to dust and moisture exposure, but their compact construction suits different usage contexts.

• Panasonic ZS40: Plastic body optimized for portability; lacks any weatherproofing.
• Sony NEX-5: Metallic chassis with a more premium feel but also no sealing.

If you plan outdoor use in challenging conditions, a protective case or cautious handling is advised for both.

Real-Life Photography: Performance Across Genres

I tested both cameras across key photography disciplines below.

Portrait Photography

• Sony NEX-5: Larger sensor produces pleasing skin tones with subtle gradation. The ability to pair with bright prime lenses (e.g., 35mm f/1.8) yields excellent bokeh, flattering subject isolation, and eye-catching portraits. Manual aperture control offers creative depth-of-field play.

• Panasonic ZS40: Small sensor and slower aperture limit background blur. Portraits are adequate in good light but can appear flat. Face detection helps but no eye detection.

Landscape Photography

• Sony NEX-5: Greater dynamic range and resolution facilitate detailed landscapes even under complex lighting. Interchangeable wide-angle lenses and manual control enhance creative composition.

• Panasonic ZS40: Compact zoom enables capturing distant landscapes without changing lenses, but smaller sensor reduces detail and dynamic range, especially in shadows.
