• Panasonic ZS45: Slightly larger and heavier (108 x 60 x 32mm; 249g), reflecting its beefier zoom lens and enhanced feature set.

The SZ5’s compactness is appealing for on-the-go users valuing portability. However, in my experience, the ZS45’s larger grip and body provide a more secure hold during longer shoots, especially when using its long telephoto zoom.

Ergonomics and control layout further illustrate the difference in target user:

• SZ5 comes with minimal physical controls and no manual exposure options, relying heavily on automatic modes.
• ZS45 offers dedicated dials and physical buttons for aperture priority, shutter priority, and manual modes, which I found essential for creative control in challenging lighting.

Summary: SZ5 excels in portability and simplicity, ideal as an easy travel companion, while ZS45 balances size with better handling and greater manual control, suiting enthusiasts wanting more camera interaction.

Sensor and Image Quality: The Heart of the Matter

Both cameras sport the same small sensor size - a 1/2.3” format sensor measuring approximately 6.08 x 4.56 mm with a sensor area around 27.7 mm². Such sensors are common in compact superzooms aiming to deliver versatility rather than elite image quality.

• The SZ5 uses a 14-megapixel CCD sensor, typical of early compact cameras its era, which generally yields good color rendition but struggles in low light due to higher noise and limited dynamic range.
• The ZS45 upgrades to a 16-megapixel CMOS sensor, which offers better noise control, faster readouts, and improved performance at higher ISOs.

Max ISO settings highlight this difference - SZ5 tops out at ISO 1600 natively (boost to 6400) while ZS45 supports native ISO up to 6400, giving it a clear edge in low-light situations.

From my lab tests and field shooting, the ZS45 images exhibit cleaner shadows and better highlight retention. This is particularly noticeable in complex lighting such as landscape golden hours or dimly lit interiors.

Display and User Interface: Evaluating Your Window into the Image

The rear LCD screen is the primary interface for framing, reviewing, and menu navigation in these cameras.

• The SZ5 sports a fixed 3-inch TFT LCD with 230k-dot resolution. It’s serviceable but noticeably coarse and dim under bright conditions.
• The ZS45 offers a 3-inch tilting screen with 1040k-dot resolution, dramatically sharper and more versatile for shooting at odd angles, such as low to the ground or overhead.

From my experience, the improved resolution and tilt mechanism on the ZS45 significantly boost usability in dynamic shooting scenarios like street or macro photography where a direct eye-level stance isn’t always practical.

Touchscreen functionality is absent in both cameras, but the ZS45’s live view autofocus and more responsive menus make it a more comfortable camera to operate for enthusiasts seeking speed and precision.

Autofocus and Performance: Speed Matters in Action

Autofocus capabilities often define whether a compact keeps up with your story or misses the moment.

• Both cameras rely on contrast-detection autofocus (CDAF) systems; neither incorporates phase-detection pixels.
• The SZ5 features 23 focus points and supports face detection with continuous AF.
• The ZS45 offers 21 focus points, face detection, and additionally supports AF tracking and live view AF, enabling better focus maintenance on moving subjects.

Burst shooting speeds reveal the ZS45 excels:

• SZ5 maxes at approximately 2 frames per second (fps), which is limiting when capturing fast action.
• ZS45 shoots up to 10 fps, a significant advantage when photographing sports, wildlife, or decisive street moments.

My real-world tests show that the ZS45 locks focus noticeably faster and maintains it more effectively during continuous shooting modes, thrilling sports and wildlife photographers who need to track subjects reliably.

Lens and Zoom: How Far Can They Take You?

Zoom versatility is a critical aspect for compact camera buyers, giving you framing flexibility without swapping lenses.

• SZ5 features a 10x zoom: 25-250mm equivalent focal length, with max aperture from f/3.1 to f/5.9.
• ZS45 ups the ante with an impressive 20x zoom: 24-480mm equivalent, f/3.3-6.4 max aperture.

The ZS45's 20x zoom practically doubles the reach compared to SZ5, opening possibilities to photograph distant wildlife or faraway architectural details without losing image quality unexpectedly.

Both lenses offer optical image stabilization, vital when using long telephoto settings handheld.

For macro enthusiasts, the ZS45’s focus capability down to 3 cm beats the SZ5’s 5 cm minimum focusing distance, allowing closer and more detailed close-ups.

Zooming versatility combined with stabilization makes the ZS45 a strong candidate for travel and nature photographers who want a one-camera solution.

Low Light and High ISO Performance: Night Owls and Venue Shooters

Small sensors are not renowned for stellar low-light performance, but software and sensor technology differences here are important.

• The SZ5’s CCD sensor and ISO ceiling limit its usefulness in darker scenes - images taken above ISO 800 show noticeable grain and color degradation.
• The ZS45’s CMOS sensor supports handheld shooting at ISOs up to 6400 with tolerable noise levels and better color fidelity.

In night photography tests, the ZS45 rendered stars and street lights cleaner and with less chromatic aberration. The improved shutter speed range (up to 1/2000s) allows capturing fast-moving subjects with wider apertures, which is helpful for evening portraits or street scenes.

Both cameras lack built-in electronic viewfinders and don’t have silent shutter modes, so shooting in completely dark environments might require additional illumination or a tripod.

Video Capabilities: Beyond Still Photography

Video recording remains an important factor for many users.

• SZ5 shoots HD 720p video at 30 fps, encoded in MPEG-4 format, sufficient for casual home movies but limited for serious videography.
• ZS45 steps up to Full HD 1080p at 30 fps, also MPEG-4, delivering crisper, more detailed footage that works well for online sharing or personal projects.

Neither camera includes microphone or headphone ports, restricting audio flexibility, but the ZS45 benefits from improved image stabilization while filming handheld.

I found the tilting screen on the ZS45 especially useful for vlogging or shooting at angles, enhancing compositional creativity.
