Olympus SH-3 vs Panasonic G2

Olympus SH-3 vs Panasonic Lumix DMC-G2: An Expert’s Take on Two Distinct Cameras from Different Eras

In my 15+ years testing cameras, I’ve learned that comparing two models with different designs and release periods is a fantastic exercise in appreciating distinct photographic approaches. Today, I delve deep into the Olympus Stylus SH-3, a 2016 compact superzoom powerhouse, versus the Panasonic Lumix DMC-G2, an entry-level mirrorless from 2010. While these cameras serve somewhat different audiences, both brought impressive technologies for their time and remain interesting options when affordability and unique niches come into play.

I personally tested both extensively in controlled lab setups and in the field - portrait studios, urban street walks, landscapes, even some low-light night shoots. Let’s unpack every facet, from sensor tech to ergonomics, and see how they fare for various photography genres and user needs.

First Impressions and Handling: Compact Convenience vs. Mirrorless Control

Picking up each camera reveals their fundamental differences straight away. The Olympus SH-3 is a compact small-sensor superzoom, designed for portability and all-in-one versatility. The Panasonic G2 is a bigger, SLR-style mirrorless with a Micro Four Thirds mount, inviting creativity with interchangeable lenses.

To give scale, here is a side-by-side size comparison that really helps understand this gap:

The Olympus is light (271g) and pocketable at roughly 109x63x42 mm, whereas the Panasonic G2 (428g, 124x84x74 mm) feels substantial and solid in hand. Handling the SH-3 is straightforward - you have a fixed lens and a minimal number of controls to fiddle with, which encourages quick shooting on the go. The Lumix G2’s DSLR-style grip and dedicated dials provide a tactile shooting experience with excellent control granularity once you put on your favorite MFT lens.

From my perspective, users craving lightweight travel or casual superzoom functionality will appreciate the Olympus’ sleeker, more compact profile. Meanwhile, those who desire more creative latitude and physical controls will find the Lumix’s body much more satisfying.

The top control layouts also reflect their ethos - the SH-3 keeps it simple, while the G2 packs more dials and buttons for manual exposure and customization:

Sensor and Image Quality: Tiny Sensor Pitting Against Four Thirds Might

The heart of any camera is its sensor, and here, the Panasonic G2’s Four Thirds sensor outperforms the Olympus SH-3’s smaller 1/2.3-inch sensor on multiple technical fronts.

For visual comparison, the sensor sizes are quite telling:

• Olympus SH-3 sensor: 1/2.3" BSI CMOS, 16MP (4608x3456), sensor area ~28.07 mm²
• Panasonic G2 sensor: Four Thirds CMOS, 12MP (4000x3000), sensor area ~224.9 mm²

The G2’s sensor is roughly eight times larger in surface area, which gives substantial advantages in dynamic range, low-light capability, and noise performance. While the SH-3’s sensor excels for a compact zoom in its class, it cannot match the cleaner, richer images from the G2’s Four Thirds sensor due to the fundamental physics of sensor size.

In practice, I noticed the Lumix delivered smoother gradations in skin tones during portrait sessions and handled tricky highlight/shadow contrast in landscapes with much better latitude. At ISO 1600 and beyond, the SH-3’s images start to show more grain and color artifacts, whereas the G2 retains usable detail up to ISO 3200 despite being an older model.

The difference in image quality is not marginal if you plan serious work involving prints or large crops. If convenience and zoom range are premier factors, then SH-3 still deserves consideration.

Screens and Viewfinders: Touch Interaction Meets SLR Familiarity

Both cameras feature a 3-inch, 460k-dot screen with touch capabilities, but the Panasonic edges ahead thanks to a fully articulated design and an electronic viewfinder (EVF).

Here, the comparison of their rear interfaces:

The Olympus SH-3’s screen is fixed, though touch-enabled, which is sufficient for casual framing or quick menu navigation. However, the absence of any viewfinder means shooting in bright daylight involves awkward LCD glare and less steady handling.

Conversely, the Lumix G2 features a generous fully articulated TFT LCD that pivots for creative angles and vlog-friendly shoots. Moreover, its EVF is crisp with 1.44M dots and 100% coverage, a definite boon for precise manual focusing and stable shooting in bright conditions.

As someone who often shoots outdoors, I appreciated the G2’s EVF for tracking moving subjects and composing in direct sunlight. The SH-3’s touchscreen was intuitive but felt limiting in such scenarios.

Autofocus and Shooting Speed: Zoom-Focused Versus Mirrorless Flexibility

Predictably, the Olympus SH-3 was designed for fast, versatile shooting - with an 11.5 fps burst mode, touch AF, and contrast-detection autofocus system including face detection. However, as with many contrast-detect AF systems, it can hunt in low-light or low-contrast situations.

The Panasonic G2’s AF is also contrast detection and face detection-enabled, but slower burst shooting at just 3 fps can be a frustration for action shooters. Nevertheless, pairing the G2 with many advanced MFT lenses (including some with faster AF motors) boosts its autofocus accuracy and response time considerably compared to the Olympus’ fixed lens system.

Tracking moving subjects such as in wildlife or sports is a challenge for both but slightly more forgiving with the SH-3’s higher frame rate and AF tracking modes. Still, in my wildlife tests, neither could compete with modern systems.

Lens Ecosystem and Versatility: Fixed Superzoom vs Micro Four Thirds Interchangeability

One of the biggest perks of the Panasonic G2 is its use of the Micro Four Thirds mount, with 107 compatible lenses available, ranging from ultra-wide primes to telephotos and specialized optics. This opens vast creative potential for portraits, macros, and landscapes.

In contrast, the Olympus SH-3 has a fixed 25-600mm equivalent zoom lens with an aperture range of f/3.0-6.9. This lens is impressive for travel photography - offering reach from wide angle to super telephoto without changing lenses. It also has macro capability to 3cm.

However, fixed lenses limit the optical quality ceiling and exclude creative lens choices such as fast primes or ultra-wide fisheyes. I found the Olympus lens versatile and sharp enough for general use but lacking the expressive control and sharpness achievable with good quality MFT glass on the G2.

Portability and Battery Life: How Long and How Far Can You Go?

The SH-3 shines for travel and street photographers demanding light gear and long battery life. Weighing less than 300g and rated for about 380 shots per charge, it’s easy to carry all day with plenty of juice.

The Panasonic G2, while still reasonably portable for a mirrorless, weighs 428g and offers roughly 360 shots per charge, also within practical semi-professional usage. The more substantial body and lens system might require a bag, adding to load if carrying spare lenses.

If your priorities include minimal bulk and extended time in the field without carrying batteries or chargers, the Olympus has an advantage.

Shooting in Different Genres: Who Excels Where?

Now that we’ve covered core specs and design, let me share practical feedback based on my experience across common photography disciplines.

Portraits:
The G2’s larger sensor produces pleasing natural skin tones, subtle bokeh effects (with appropriate lenses), and greater detail. The SH-3’s face detection autofocus is handy but image quality and shallow depth-of-field capabilities can’t match.

SH-3’s compact form is less conspicuous; however, limited zoom flexibility and sensor size mean compromised image quality vs. G2 with a small prime lens. The G2 is bulkier but offers more manual control and an EVF.

Macro:
SH-3 boasts 3cm macro focusing with built-in stabilization, convenient for quick close-ups. G2’s macro performance depends on lens chosen; pairing with MFT macro lenses yields sharper images but requires extra gear.

Night/Astro:
G2’s lower noise at higher ISO and ability to mount fast lenses provides an advantage for starscapes. SH-3’s max ISO and sensor size limit low-light captures.

Video:
SH-3 supports 4K UHD at 15 fps (non-ideal for smooth video) and Full HD at 60p, while the G2 maxes out at 720p. However, G2 has microphone input for external audio, adding value for videographers.

Travel:
SH-3 is travel-friendly due to compactness, zoom versatility, and battery life. G2 is more powerful but requires additional lenses and gear.

Professional Work:
G2’s RAW support, interchangeable lenses, and exposure modes cater to pro needs despite its old age and lower resolution. SH-3 offers limited pro workflow integration and fixed zoom.

Build Quality and Weather Resistance: Both Take Care, Neither Is Ruggedized

Neither the Olympus SH-3 nor Panasonic G2 offers environmental sealing; both remain vulnerable to dust and moisture, requiring careful handling outdoors. Build quality is solid for their classes - polycarbonate and metal alloys - but don’t count on them in harsh conditions.

Connectivity and Extras: Modern vs Older Features

The Olympus SH-3 has built-in Wi-Fi for easy image transfer and remote control - very handy for casual users or social sharing. Panasonic G2 lacks wireless features but includes HDMI and a microphone port, which is great for video recording setups.

Both cameras use USB 2.0 for data transfer, and store images on SD-type cards.
