Olympus VG-120 vs Panasonic Lumix DMC-G2: A Practical Comparison for Photographers

When it comes to selecting a camera, the options often span a broad spectrum - from simple, pocket-sized compacts to more versatile mirrorless systems. Today, I’m diving deep into two distinctly different cameras from the early 2010s era: the Olympus VG-120, an ultracompact point-and-shoot, and the Panasonic Lumix DMC-G2, an entry-level mirrorless interchangeable lens camera. Though they debuted around a similar time frame, these cameras serve very different users and shooting styles. Drawing on my extensive experience testing hundreds of cameras, I’ll break down their strengths and weaknesses so you can gauge which fits your photography goals and budget.

Let’s start by getting a feel for their physicality and design.

Pocketability vs. Presence: The Physical Size and Ergonomics Duel

The Olympus VG-120 is delightfully small and thin, measuring just 96 x 57 x 19 mm and weighing a mere 120 grams. Its ultracompact body slips effortlessly into any pocket or purse, making it a quintessential grab-and-go camera for casual photographers or travelers prioritizing portability.

Conversely, the Panasonic G2 is a more substantial tool. Its SLR-style mirrorless body measures 124 x 84 x 74 mm and weighs 428 grams. While it’s still compact compared to traditional DSLRs, it demands more space in your bag and has a bulkier hand presence, reflecting its more advanced control scheme and interchangeable lens system.

This size difference dictates much of what you can expect ergonomically - the G2 feels more solid in hand, with a deeper grip and more dedicated buttons. The VG-120’s minimalist controls align with its casual use-case, but you sacrifice tactile quick access to key settings.

Design Details: Controls and User Interface

Looking down from above, the Panasonic G2 exudes the classic DSLR-influenced layout, with dials for aperture/shutter priority, a mode dial, and buttons for ISO, drive modes, and more. This affords speedy manual adjustments and a higher level of creative control once you understand the layout.

The Olympus VG-120, in contrast, keeps things simple with fewer physical controls, relying heavily on menu navigation. There’s no dedicated manual exposure modes; the camera handles everything in automatic or scene presets.

The G2 also shines with a fully articulating touchscreen LCD and an electronic viewfinder - crucial for shooting in bright environments or for users who prefer composing at eye level. The VG-120 has a fixed 3-inch LCD without touchscreen capability and omits any viewfinder.

Sensor Tech and Image Quality: Size Matters

Under the hood, the Panasonic G2 employs a Four Thirds-sized CMOS sensor measuring 17.3 x 13 mm, vastly larger than the VG-120’s 1/2.3-inch CCD sensor at 6.17 x 4.55 mm. Sensor size profoundly impacts image quality, noise performance, and depth of field control.

The VG-120’s small sensor and 14-megapixel resolution means images can look decent in good light but fall apart faster at higher ISOs. The Olympus tops out at ISO 1600 native, which I found to be noisy and grossly limiting for low-light work.

The G2’s sensor and processor combo (Venus Engine HD II) capture 12-megapixel images with excellent dynamic range (~10 stops) and much better high ISO quietness, shooting clean images up to ISO 1600 and somewhat usable up to ISO 3200 or 6400 for emergencies. It also supports RAW format capture, giving photographers latitude in post-processing - a huge plus for enthusiasts and pros.

My test shots confirmed what sensor specs suggested: Panasonic G2 images exhibit richer tonality and better shadow recovery, while the Olympus struggles outside bright daylight conditions.

Screen and Viewfinder Experience

The VG-120’s 3-inch TFT LCD screen offers just 230k dots - noticeably low resolution by today’s standards or even compared to the G2’s 460k-dot wide-angle TFT display capable of swiveling for creative angles and selfies.

Meanwhile, the G2’s electronic viewfinder (EVF) provides 100% coverage and a 0.55x magnification. This gives a DSLR-like shooting experience, crucial when shooting action or in bright sunlight. The VG-120 does not have a viewfinder, forcing reliance on its LCD in all conditions, which can be tricky outdoors.

The integration of touchscreen on the G2 also smooths AF point selection and menu navigation, an experience missing on the VG-120.

Picture Quality in the Real World: A Gallery to Judge By

Here are comparative images shot side-by-side with both cameras in varied lighting and subjects:

• Portraits: The Panasonic G2 renders skin tones naturally with good color accuracy and pleasing bokeh on prime lenses. The VG-120’s smaller sensor and lens aperture limit shallow depth of field, producing flatter backgrounds.
• Landscapes: The G2’s sensor resolution and dynamic range allow crisp details and well-controlled highlights and shadows. The VG-120’s images are softer, with less tonal range.
• Low Light: The VG-120’s noise rises dramatically after ISO 400, whereas the G2 maintains usable detail and color up to ISO 1600.
• Motion: The G2’s faster shutter speeds and continuous shooting help freeze action better.

Autofocus Systems: Speed vs Simplicity

The VG-120 relies on contrast-detection autofocus with face detection but lacks continuous AF tracking or manual focus options. Its focus speed is adequate for static scenes but sluggish with moving subjects.

The Panasonic G2 steps up with a contrast-based AF system enhanced by multi-area tracking and face detection, plus the ability to select focus points or zones manually. It also supports continuous AF during burst shooting at 3 fps, helpful for sports or wildlife photography at an entry level.

While neither can compare to modern hybrid or phase-detect AF systems, the G2 provides a more responsive and flexible autofocus experience that will satisfy newcomers who want to grow their photography skills.

Build Quality and Weather Resistance

Both cameras have plastic bodies with no official weather sealing or durability claims. The VG-120’s ultracompact design inherently limits ruggedness, while the Panasonic G2 feels more solid and better assembled but still is not targeted at outdoor abuse.

If weather-proofing is a deal-breaker, neither model fits - you’d want to look elsewhere.

Lens Ecosystems and Versatility

This is where the G2 really shines. The Micro Four Thirds mount is one of the most popular mirrorless lens systems, giving access to over 100 lenses ranging from wide-angle to super-telephoto and specialized macro optics from Panasonic, Olympus, Sigma, and third-party brands.

The VG-120 has a fixed zoom lens equivalent to 26-130mm f/2.8-6.5. This range covers casual shooting well but limits creative depth, wide-angle landscapes, and telephoto reach.

For anybody serious about versatility, creative control, or specific genres like wildlife or macro photography, the G2’s lens ecosystem is a massive advantage.

Battery Life and Storage

The Panasonic G2 impresses with a claimed 360 shots per charge under CIPA guidelines, almost double the VG-120’s 160 shots. In the field, this translates to less worrying about recharges or carrying multiple spare batteries.

Storage-wise, both use SD or SDHC cards, but the G2 also supports SDXC, allowing larger cards suited for RAW shooting and video recording.

Wireless and Connectivity

Neither camera offers Wi-Fi, Bluetooth, or GPS, unsurprising for their generation. The G2, however, includes HDMI output and a microphone input for better video setups, lending itself more to multimedia creators.

Video Capabilities: Modest but Functional

Both shoot HD video at 720p, with the G2 supporting AVCHD Lite format and Motion JPEG, while the VG-120 records Motion JPEG only. The G2’s video controls and external mic port provide higher quality sound options - a boon for vloggers or amateur filmmakers.

The VG-120 is very basic here, intended for casual video capture only.
