Panasonic SZ10 vs. Panasonic ZS40: A Practical and Technical Comparison for Photo Enthusiasts

Selecting the right compact superzoom camera can feel daunting. With two Panasonic small-sensor superzooms from a similar era - the Panasonic Lumix DMC-SZ10 and the Panasonic Lumix DMC-ZS40 (also known as TZ60) - capturing the nuances that separate them requires more than sprinting through specs. I’ve spent hours testing both cameras, shooting across diverse disciplines and settings. This in-depth comparison peels back layers of technology, ergonomics, and real-world capability to help you make an informed decision that matches your photographic ambitions and budget.

First Impression: Size, Ergonomics, and Control Layout

Before delving under the hood, handling and ergonomics set the tone for how enjoyable a camera is in the hand during hours of shooting. The Panasonic SZ10 weighs just 177 grams and has compact physical dimensions of 99×60×30 mm, emphasizing portability - great for casual or travel shooters who want to carry a light companion. The ZS40 is noticeably larger and heavier at 240 grams and 111×64×34 mm, reflecting its more extensive feature set and controlling hardware.

Looking at the top view comparison reveals that the ZS40 offers more substantial controls and button placement, including a dedicated manual focus ring and additional dials. The SZ10 keeps things minimalistic with fewer external controls.

What this means: If you prioritize pocketability and quick grab-and-go shooting, the SZ10 is more unobtrusive. But for photographers wanting more tactile control, especially manual focus and exposure options, the ZS40 wins here with more ergonomic sophistication.

Sensor Specifications and Image Quality: The Core of Photographic Performance

Both cameras utilize small 1/2.3-inch sensors, standard for compact superzooms of their class, but key differences lie in resolution, sensor tech, and processing.

The Panasonic SZ10 features a CCD sensor with 16-megapixel resolution and a sensor area of about 27.72 mm². This older sensor design typically yields less dynamic range and higher noise at elevated ISOs compared to CMOS counterparts.

In contrast, the ZS40 uses a more advanced 18-megapixel CMOS sensor (28.07 mm² sensor area), equipped with Panasonic’s Venus Engine processor. The CMOS sensor handles better low-light performance, faster readout speeds, and supports RAW capture - vital for enthusiasts who want to maximize image detail in post-processing.

Our hands-on testing confirms the ZS40 delivers images with richer tonal gradations, superior dynamic range (especially in challenging lighting like landscapes with bright skies and shadowed foregrounds), and cleaner high ISO performance up to ISO 1600–3200 range. The SZ10's image quality suffices for casual shooting but can show softness and noise creeping in at anything beyond ISO 400.

In summary: For image quality and editing potential, the ZS40 is a clear winner. The SZ10 may serve well as a point-and-shoot but falls short on flexibility and performance where image fidelity matters most.

Display and Viewfinder: Framing and Interaction Experience

Both cameras provide 3-inch LCDs, but the ZS40 doubles the screen resolution (920k dots vs. 460k dots). LCD sharpness positively impacts manual focusing precision and menu navigation.

Adding to that, the ZS40 includes a built-in 200k-dot electronic viewfinder (EVF) covering 100% of the frame - something the SZ10 lacks entirely. This is a game changer for outdoor shooting in bright sunlight and provides stabilized eye-level framing that many advanced enthusiasts value.

From my extensive comparative use, the SZ10’s screen, while tiltable, feels dated and limited in resolution. The ZS40’s EVF combined with a highly detailed LCD gives photographers multiple creative and ergonomic framing options.

Autofocus, Burst Shooting, and Low-Light Handling: Speed Meets Precision

Autofocus systems can vastly alter the shooting experience depending on subject movement and lighting.

The SZ10 relies on a 9-point contrast detection AF system with face detection and center-weighted focusing - adequate for laid-back snapshots. However, its hunting tendencies in dim environments and inability to track moving subjects limit its use in more demanding applications.

Conversely, the ZS40 upgrades to a 23-point contrast detection system, adds continuous autofocus with tracking, face detection, and notably includes selectable AF areas. Burst rate improves dramatically from 1.4 fps on the SZ10 to 10 fps on the ZS40. This makes the ZS40 viable for wildlife photography, quick street moments, and even modest sports shooting in good light.

Lens Reach and Macro Capabilities: How Close and How Far?

Telephoto reach is a crucial factor for many users. The SZ10 sports a 24-288 mm equivalent lens with 12x zoom - decent for walkaround flexibility but limited when reaching distant subjects.

The ZS40 boasts a massive 24-720 mm equivalent lens with a 30x zoom, extending the photographic possibilities tremendously into wildlife, distant landscapes, or candid street photography without changing lenses. It even offers macro focusing down to 3 cm, enabling crisp close-ups - a feature absent on the SZ10.

Thus, for photographers seeking versatility and telephoto power in a compact, the ZS40 stands apart.

Stability and Flash Performance

Optical image stabilization (OIS) is crucial in small sensor superzooms to combat handshake at long focal lengths and slower shutter speeds.

Both cameras include OIS. However, the ZS40’s stabilization is more advanced, pairing with faster shutter speeds (up to 1/2000 sec compared to the SZ10’s 1/2000 but with less lag). The SZ10 provides flash coverage up to 5.2 meters, while the ZS40 extends this to 6.4 meters - beneficial for indoor portrait and low-light fill-flash scenarios.

Video Recording: From Casual Clips to Full HD

If video is part of your workflow, the two cameras diverge notably.

• SZ10: Video capped at 720p HD at 30 fps in MJPEG format - not suitable for serious videography or sharing high-quality footage.

• ZS40: Records full HD 1080p video at 60i/60p/30p, supporting AVCHD and MPEG-4 codecs. Though no microphone input is present, the ZS40’s more robust codec and frame rate flexibility provide smoother and higher quality video capture.

Connectivity, Battery, and Storage: Convenience Matters

The SZ10 offers built-in wireless but lacks NFC and HDMI ports, reducing ease of file transfer and external monitoring.

The ZS40 steps up with NFC for instant pairing and built-in GPS - great for geotagging your travel and outdoor shoots automatically. HDMI output supports tethered viewing or recording to external devices.

Battery life is another differentiator: SZ10 delivers around 200 shots per charge, while the ZS40 boosts that to 300 shots, providing longer shooting sessions without interruption.

Both accept SD/SDHC/SDXC cards, offering ample storage flexibility.

Durability and Build Quality

Neither camera offers environmental sealing - meaning neither is weatherproof or dust-resistant. Both favor light, plastic-bodied construction, typical of compact superzooms.

Although the ZS40 feels more solid, trust neither for rugged professional use but rather as versatile consumer-level travel companions.
