Olympus SH-3 vs Panasonic Lumix G3: A Hands-On Comparison for the Practical Photographer

As someone who’s spent years handling cameras ranging from budget compacts to high-end mirrorless workhorses, I know the frustration of choosing gear that fits both your shooting style and your wallet. Today, I’m diving into two quite different cameras from Olympus and Panasonic: the Olympus Stylus SH-3 and the Panasonic Lumix DMC-G3. Both are on the affordable side and have their own appeal - so which one deserves your hard-earned cash?

I’ve put these cameras through their paces across genres, from portraits to landscapes, wildlife to travel photography. Along the way, we’ll compare design, sensor tech, autofocus chops, and more, peppered with practical insights you won’t find just in spec sheets. Let’s get started.

Getting a Feel: Size, Build, and Handling

First impressions matter – and when you’re hauling a camera all day, size and grip comfort become priorities. The Olympus SH-3 is a compact superzoom, meaning it’s small, pocketable, and built for convenience. The Panasonic G3 is an entry-level mirrorless with an SLR-style design - larger but with grip-focused ergonomics.

Looking at the physical sizes:

• Olympus SH-3: Measures 109x63x42mm, weighs 271g
• Panasonic G3: Larger at 115x84x47mm, heavier at 336g

The SH-3 feels like a cool little travel buddy: light, easy to tuck into a jacket pocket, or slide into a small accessory bag. It leans heavily into convenience over substance - plastic body but surprisingly solid for what it is.

By contrast, the G3 has more of a “club for your thumbs” vibe - handy for photographers seeking control, with bigger dials, a proper grip, and an electronic viewfinder. That mirrorless design means motors and hardware add heft, but you get a tighter shooting experience with less zombie arm syndrome.

Want more control and heft? G3 wins. Want lightweight portability? SH-3 is your pal.

Top Controls and Usability: Can You Work Fast?

When shooting, instinctive control layouts make a world of difference. Neither camera is a pro beast, but each has its own approach.

The SH-3’s top panel is streamlined. You get a mode dial, basic zoom rocker, shutter release, and power switch. Limited buttons mean fewer clubs for thumbs, which beginners might appreciate but advanced users could find somewhat restricting. No customizable buttons, no dedicated ISO or exposure compensation dials - the menu does the heavy lifting, slowing quick changes.

In contrast, the Panasonic G3’s top plate is more involved. It features a mode dial with PASM modes (more on that later), exposure compensation dial, and a built-in pop-up flash with hot shoe for external flashes. Getting to ISO, aperture, and shutter speeds is sharper and quicker.

For snapping street shots or running wildlife, quick access matters. I found the G3 a better companion here, while the SH-3 suits casual point-and-shoot days where you fuss less.

Sensor Technology and Image Quality: A Fundamental Divide

This is where the biggest difference lies and why these cameras speak to vastly different users.

• Olympus SH-3: Uses a 1/2.3” BSI-CMOS sensor (6.17x4.55mm), 16MP native resolution
• Panasonic G3: Equipped with a much larger Four Thirds CMOS sensor (17.3x13mm), also 16MP

Despite matching megapixels, the sensor size difference is dramatic. The G3’s Four Thirds sensor is roughly 8x larger in surface area, which translates to better image quality, dynamic range, and noise performance - especially in low light.

From my hands-on lab testing with these cameras, shots from the SH-3 show more noise and less detail retention beyond ISO 800, while the G3 maintains crispness and cleaner shadows even at ISO 1600 and beyond.

Further, the G3 offers uncompressed RAW shooting, giving you flexibility in post. The SH-3 also supports RAW - surprising for a compact - but its smaller sensor caps the data quality at input.

Bottom line: if image quality is king for you - portraits, landscapes, low light - this Four Thirds sensor gives the G3 a solid advantage.

Viewing and Framing: Screen and Viewfinder Considerations

How you compose is deeply affected by your viewing options.

Both cameras have a 3-inch screen at 460k dots and touch support. However, Panasonic’s G3 screen is fully articulated - perfect for awkward angles, video selfies, or shooting macro close to the ground. The Olympus SH-3’s fixed screen limits flexibility but remains bright outdoors.

Crucially, the G3 includes a 1440-dot electronic viewfinder (EVF) that covers 100% of the frame - indispensable for bright sunny days when LCD viewing becomes impossible. The SH-3 has no EVF, relying solely on the LCD.

For street photography or travel in harsh light, the G3’s EVF gives a huge edge in accuracy and composure speed. The SH-3 is strictly a rear-screen shooter.

Autofocus: How Fast and Accurate?

Autofocus (AF) performance can make or break candid, sports, or wildlife shooting.

• The Olympus SH-3 uses contrast-detection AF only with face detection and tracking, plus touch AF. It boasts a burst rate of 11.5 fps, which is quick, but AF hunting slows things down.
• The Panasonic G3 offers contrast-detection AF with 23 focus points and face detection. It maxes out at 4 fps continuous shooting.

While the SH-3 can shoot faster bursts, the G3’s predictable AF accuracy and manual focus support allow better control in tricky focusing conditions (macro, low light).

I tested both on moving targets: the SH-3 struggled (lagging and hunting), while the G3 more reliably locked onto subjects. However, neither camera has phase-detection AF or animal eye AF, so for serious wildlife or high-speed sports, you’ll quickly feel limited.

Lens Systems and Flexibility: Superzoom vs Interchangeable

Here we diverge sharply in versatility.

• The Olympus SH-3 sports a fixed lens with an insane 25-600mm equivalent zoom range (24x), aperture F3.0-6.9.
• The Panasonic G3 uses the Micro Four Thirds (MFT) mount, compatible with over 100 native lenses plus adapters for older glass.

If your thing is an all-in-one with no fuss, a superzoom like the SH-3’s is tempting. Imagine wildlife or travel shots without swapping lenses – one lens rule simplifies packing and shooting.

However, the small sensor mandates longer depth of field and lower bokeh potential. Optical quality can also vary across such a wide zoom range.

The G3’s system opens a door to creative freedom: from ultra-wide landscapes to prime lenses for shallow portraits and macro work. You’re only limited by your budget.

If you anticipate growing as a photographer or need specialized optics, the G3 wins hands down. If you want “grab and go” simplicity in an ultracompact body, the SH-3 fills a niche.

Real-World Photography Test Samples

Seeing is believing, so I took test shots with both cameras in mixed conditions:

• Portraits with SH-3: Skin tones are OK but lack the creamy bokeh and fine detail of the G3.
• Landscape scenes: The G3 retains vibrant colors, excellent dynamic range, and sharpness across the frame.
• Telephoto wildlife shots from SH-3 are convenient but show softness and noise rise beyond 300mm equivalent.
• Macro shots lean heavily to G3 with dedicated macro lenses and manual focus precision.

I recommend the SH-3 as a casual snapshot tool ideal for vacationers or quick wildlife snaps, whereas the G3 caters better to enthusiasts wanting artistic control and image quality.

Video Capabilities: Can They Shoot More Than Still?

Let’s talk video, since both cameras offer HD recording but diverge substantially.

• The Olympus SH-3 can shoot 4K UHD at 15 fps (fairly unusable for smooth video), 1080p at up to 60fps, and supports basic in-camera stabilization via sensor-shift.
• The Panasonic G3 provides 1080p 60fps video with AVCHD and Motion JPEG formats, no 4K, and no in-body stabilization (you rely on lens stabilization if available).

Neither offers microphone or headphone jacks, disappointing for vloggers or audio-heavy shoots.

The SH-3’s sensor-shift IS helps handheld video stability more than the G3’s lack of stabilization, but the lower resolution and frame rate limitations cede the advantage to Panasonic for smooth 1080p recording.

In summary, video pros: SH-3 for casual shooters with stabilization, G3 for enthusiasts prioritizing full HD recording quality.

Battery Life, Storage, and Connectivity

• The Olympus SH-3 claims 380 shots per charge, powered with a LI-92B battery, and it supports SD/SDHC/SDXC cards plus internal memory.
• The Panasonic G3 is rated for 270 shots, also using SD cards, but no internal memory.

In real usage, the SH-3’s battery life impressed me considering its tiny size and compact form.

On the connectivity front, SH-3 includes built-in wireless (Wi-Fi probably) but no Bluetooth or NFC. The G3 lacks any wireless features, which shows its slightly older release date.

USB and HDMI ports are common to both, but no USB charging support.

Build Quality and Environmental Resistance

Neither camera sports weather sealing or ruggedized build.

Both are best used in controlled environments or drier weather.
