Today, we put two intriguing contenders head-to-head: the Olympus VG-120, an older ultracompact model, and the much newer Panasonic Lumix DMC-ZS70 (also known as Lumix DMC-TZ90), a feature-packed small sensor superzoom. Both cameras target users who want portability and versatility, but they differ widely in technology, features, and real-world performance.

Drawing on extensive hands-on testing and industry-standard evaluation techniques, we'll break down their strengths and weaknesses across multiple photography scenarios. This comprehensive comparison will help you identify which camera aligns best with your creative ambitions and budget.

Exploring Size and Ergonomics: How These Cameras Feel in Your Hands

A camera’s physical design plays a crucial role in usability, especially when you're out shooting for hours or capturing spontaneous moments. Compactness offers convenience, but it must be balanced with comfortable handling.

The Olympus VG-120 is ultra-slim and lightweight, fitting comfortably in nearly any pocket. However, this compactness limits its physical controls and grip security. Its slim body lacks a dedicated grip, which can impact steadiness especially during longer shoots or telephoto zoom use.

The Panasonic ZS70, in contrast, is noticeably larger and heavier but offers a more substantial grip and easier-to-access buttons. Its design supports a hands-on shooting experience favored by enthusiasts and hobbyists who want quick, tactile control over camera settings. This means the ZS70 is less pocket-friendly but better suited for active use and extended sessions.

Sensor, Image Quality, and Processing: The Heart of Photography

Sensor technology and image processing algorithms determine the sharpness, detail, noise performance, and color reproduction of your photos. To truly evaluate these cameras, we must delve into their sensors and processors.

Olympus VG-120 relies on a 14 MP CCD sensor, once common in compact cameras but now largely surpassed in performance by modern CMOS designs. CCD sensors excel in color accuracy and smooth gradations at base ISOs but generate more noise at high sensitivities, limiting low-light usability.

Panasonic ZS70 uses a back-illuminated CMOS sensor with 20 megapixels, offering several advantages: improved light gathering, faster readout speeds, and generally better high ISO performance. The Venus Engine processor further enhances image quality by reducing noise while preserving details, something especially noticeable in low-light situations.

Practical Impact

• The ZS70 produces sharper images with more detail, especially visible when printing or cropping.
• The Olympus can deliver pleasant color rendition in bright daylight but struggles when ISO sensitivity exceeds 400.
• High dynamic range scenes are better handled by the Panasonic, with more latitude in highlights and shadows.

Both cameras include an antialiasing filter to reduce moiré patterns but at the slight cost of micro-detail sharpness. Overall, the Panasonic’s sensor and processing combo firmly outclass the older Olympus in image quality.

Control Layout and User Interface: How Intuitive Can Your Workflow Be?

An intuitive interface reduces friction while shooting, allowing you to focus on creativity instead of fumbling through menus or controls.

The Olympus VG-120 incorporates a very basic control scheme fitting its budget ultracompact category:

• No manual exposure modes, aperture priority, or shutter priority - it's fully automatic.
• Limited exposure compensation and no on-the-fly ISO adjustments.
• Basic 3-inch fixed TFT color LCD (230k resolution).
• No touchscreen or electronic viewfinder.

The Panasonic ZS70 upgrades this experience dramatically:

• Manual exposure modes (PASM), exposure compensation, and ISO settings give you creative control.
• Touchscreen and tilting LCD (3", 1040k resolution) for easy framing from unique angles.
• Built-in electronic viewfinder with excellent coverage and magnification.
• Numerous autofocus options, including face, tracking, and continuous AF.

The LCD comparison shows the ZS70’s clear, bright, and versatile touchscreen experience versus the basic, fixed LCD on the Olympus, which can make composition and menu navigation tedious.

Our Take: For those who want deeper photographic control, the ZS70’s interface offers a significant leap forward. Beginners may find the Olympus interface simpler but will outgrow it quickly.

Autofocus and Performance: Capturing Momentary Magic

Autofocus performance defines how well you can seize fleeting moments - a critical factor for wildlife, sports, and street photography.

The Olympus VG-120 features a fundamental autofocus system reliant on contrast detection without continuous AF or tracking. While face detection is a useful addition, it lacks speed and precision, especially in low contrast or fast-moving scenes.

The Panasonic ZS70’s autofocus system is more modern and complex. It supports:

• A dense AF point array (49 points).
• Continuous autofocus that tracks moving subjects.
• Selective AF with responsive touch focus.
• AF tracking that locks onto faces and objects.

The 10 frames per second burst shooting is another asset for wildlife or sports photographers who need to capture sequence shots with reasonable reliability.

Result: For any dynamic photography - moving animals, athletes, or street scenes - the ZS70 is vastly superior, offering the speed and accuracy modern photographers require.

Shooting Versatility: Zoom, Macro, and Special Modes

Zoom range and macro capability are key for users who want flexibility without switching lenses.

The Olympus VG-120’s 5x zoom offers basic framing flexibility but pales compared to the Panasonic’s 30x superzoom (equivalent to 24-720 mm full frame). This vast range makes the ZS70 perfect for capturing wide vistas and distant wildlife alike.

Macro shooting is notable on the ZS70, allowing you to focus as close as 3 cm - ideal for detailed flower or insect shots. The VG-120’s minimum focus distance is 7 cm, sufficient but less versatile.

Given the lack of built-in image stabilization on the Olympus, handheld shots toward the longer end of its zoom range demand faster shutter speeds or tripods. The Panasonic’s optical image stabilization compensates effectively for handshake, significantly improving handheld usability at telephoto and low light.

Video Capabilities: Capturing Motion

If you want to incorporate video into your storytelling, camera video specs matter.

While the Olympus only records 720p HD video at 30 fps in the older Motion JPEG format, the Panasonic ZS70 offers full 4K UHD video, vastly higher resolution and modern codecs. The ZS70 also supports creative 4K photo modes for extracting stills from video frames, useful for action shots.

The lack of microphone or headphone ports on both models limits serious videography, but stabilization on the ZS70 enhances smooth handheld video capture.

For vloggers or aspiring filmmakers, the Panasonic ZS70 clearly wins on video functionality.

Battery Life and Storage: Practical Considerations on the Go

Reliable power and storage are essentials for travel and photo sessions.

The Panasonic ZS70 outperforms the Olympus with an estimated 380 shots per charge, more than double VG-120’s rated 160. For travel or extended outings, this translates to fewer battery swaps or recharges.

Both cameras utilize standard SD cards, but the ZS70’s support for SDXC allows larger capacity cards for long 4K video recordings and bulk photo sessions.
