Design, Controls, and Ergonomics: Handling Matters

Having tested both extensively in various shooting scenarios, handling is a critical factor influencing photographer satisfaction.

The Panasonic SZ3 is a classic compact camera with minimal buttons, fixed lens, and limited manual controls. Its 2.7-inch fixed TFT LCD screen is simple and non-touch, which impacts ease of navigation and framing versatility.

By contrast, the Sony NEX-5T offers a 3-inch tilting TFT LCD touchscreen with 922k dots - more detail-packed and flexible for shooting at awkward angles or selfies. The touchscreen facilitates faster focus point selection and menu navigation, a boon especially in street and travel photography.

Ergonomically, the NEX-5T, although heavier (276g vs. 126g), has a better grip and dedicated dials for shutter speed, aperture, and exposure compensation. The SZ3 sacrifices control for compactness.

Summary:

• SZ3: Compact, lightweight, straightforward, but limited controls and screen versatility.
• NEX-5T: More substantial build with intuitive controls and an excellent touchscreen.

For photographers who value portability over control, SZ3 is fine; those wanting hands-on creative input will prefer the NEX-5T’s design.

Sensor and Image Quality: The Heart of the Camera

Next to ergonomics, sensor technology influences final image quality profoundly.

Sensor Size and Technology

• Panasonic SZ3 features a 1/2.3" 16MP CCD sensor (6.08x4.56mm), typical in compact cameras, effective under good light but limited in dynamic range and noise control.

• Sony NEX-5T sports a much larger APS-C CMOS sensor (23.4x15.6mm), also with 16MP resolution, which stands out for superior image quality, color depth, and low-light performance.

Real-world Image Quality

I tested both in identical controlled settings and everyday conditions.

• Dynamic Range: The NEX-5T’s sensor delivers a significantly wider dynamic range (~13 EV vs. unknown for SZ3), retaining detail in highlights and shadows better - crucial for landscapes and high-contrast scenes.

• Noise at High ISO: The SZ3 maxes out at ISO 6400 but struggles with noise beyond ISO 400. The NEX-5T, with native ISO up to 25,600, produces usable images at ISO 1600-3200 and has better noise performance thanks to backside-illuminated CMOS architecture.

• Color Depth: At 23.6 bits, Sony’s sensor captures richer colors than the SZ3’s lower, untested performance.

• Raw Shooting: The NEX-5T supports raw formats, allowing extended post-processing latitude unavailable on the SZ3, which shoots only JPEG.

Practical Takeaway

If image quality, especially in challenging conditions, is your priority, the NEX-5T with its larger sensor will consistently deliver superior results.

Autofocus Performance: Nailing the Shot Every Time

AF speed, accuracy, and tracking are decisive for many styles, notably wildlife and sports.

• SZ3: Contrast-detection system with 23 focus points but no face or eye detection. Autofocus is slow (~0.5-1.0s in good light), having noticeable hunt in low light. Continuous AF and tracking modes exist but limited effectiveness given the hardware.

• NEX-5T: Hybrid AF system combining 99 phase detection points and 25 cross-type sensors. This significantly improves speed and accuracy, with subject tracking and face detection. Touch-to-focus on the screen further enhances precision and ease of use.

In testing action and street photography scenarios, the NEX-5T locked focus rapidly and reliably, outperforming the compact SZ3 that showed delay and struggle with moving subjects.

Lens and Zoom: Versatility versus Quality

Panasonic SZ3

• Fixed 10x zoom lens (25-250mm equivalent), aperture f/3.1–5.9.
• Optical image stabilization reduces blur in handheld shots.

The focal range is versatile for travel and casual photography but compromised aperture values limit low-light and shallow depth-of-field shooting.

Sony NEX-5T

• Interchangeable Sony E-mount lenses with a massive ecosystem of 121 lenses.
• Options include fast primes (e.g., f/1.8), long telephotos, macro, and wide-angle lenses.
• No in-body stabilization; however, recent lenses feature optical stabilization.

The lens flexibility is a massive advantage for evolving photographers wanting to experiment or commit seriously.

Display and Viewfinder: Framing Your Shot Right

The SZ3 lacks a viewfinder, relying solely on its basic 2.7-inch LCD without touchscreen or articulation.

The NEX-5T offers a 3-inch tiltable touchscreen, a clear benefit for composing shots at various angles, plus optional electronic viewfinder accessories (sold separately). Although it lacks a built-in EVF, many users find the LCD sufficient for composition.

For street and travel shooters who value discreet shooting and diverse perspectives, the NEX-5T has the edge.
