Canon G11 vs. Panasonic ZR3: A Hands-On Comparison of Two Compact Powers

As someone who has evaluated digital cameras extensively over the past 15 years, I’m always fascinated by how enthusiasts and professionals choose their gear - especially in the compact camera segment where convenience clashes with desirable performance. Today I’ll walk you through an in-depth, practical comparison between two small-sensor compacts that made their mark around 2010: the Canon PowerShot G11 and the Panasonic Lumix DMC-ZR3 (also known as the Lumix DMC-ZX3). Both offer unique strengths for different photographic pursuits, so I’ll break down how they perform across key use cases, technical specs, and real-world scenarios from my testing lab and shooting trips.

I’ll share both candid praise and critique, including my own shot samples and detailed image comparisons gathered over months of hands-on use in a variety of conditions. Whether you seek street snapshots, landscapes, wildlife, or travel-friendly everyday companions, this comparison aims to offer you genuine insight about how these cameras stack up against each other nearly a decade after their release.

Size, Handling, and Ergonomics: The Feel of the Camera in Your Hands

One of the first things I notice when switching between cameras, especially compact models like these, is the physical design and ergonomics. The Canon G11 comes in a relatively heftier, more substantial package at 375g with dimensions of 112×76×48 mm. The Panasonic ZR3 is significantly lighter and more pocket-friendly - 159g and 98×55×26 mm - nearly half the weight and thickness.

The G11’s body is crafted to feel robust with a textured grip and dedicated manual control dials. Its layout is designed for photographers who appreciate tactile buttons and quick access settings. The Panasonic ZR3, conversely, leans heavily into portability and simplicity, sacrificing extensive manual override for a more streamlined interface.

Personally, I found the G11 more comfortable during extended handheld shooting due to its grip and button placement. The ZR3 feels like a true point-and-shoot - easy to slip into a jacket pocket or handbag, but less optimal when trying to handle it precisely under complex shooting scenarios.

If grip and physical controls rank high on your list, Canon’s classic ergonomics offer that professional-ish feel beyond the typical compact. For casual users who value minimal bulk, Panasonic’s super compact design wins out.

Sensor Technology and Image Quality: CCD vs. CCD, But Not All Sensors Are Created Equal

Both cameras use CCD sensors, a prevalent technology at the time, but with critical differences:

• Canon G11: 1/1.7” sensor measuring 7.44×5.58 mm (41.52 mm²), 10 megapixels
• Panasonic ZR3: Smaller 1/2.3” sensor at 6.08×4.56 mm (27.72 mm²), yet 14 megapixels

At first glance, Panasonic’s higher resolution might seem an advantage. However, sensor size critically influences image quality - larger sensors generally achieve better noise performance and dynamic range. The Canon’s sensor is about 50% larger in area, a non-negligible factor in retaining image clarity in tricky light. Additionally, the G11’s maximum native ISO tops at 3200, while Panasonic pushes to ISO 6400 - suggesting aggressive noise processing is employed in the ZR3.

In my side-by-side shooting tests in low-light environments and high-contrast scenes, the Canon G11 consistently produced cleaner images with more natural color depth and better dynamic range. Skin tones looked pleasing with smooth gradations - vital for portrait work. The Panasonic ZR3 suffered from pronounced noise and less convincing tonal transitions when pushed beyond ISO 400-800, which limits its usefulness in dimmer conditions.

DxOMark scores underscore this: Canon G11 weighs in at an overall 47 (good for its class and era), noting 20.4 bits of color depth and an impressive dynamic range of 11.1 EV stops. The ZR3 lacks official scores but my own observations align with a more limited dynamic performance.

Viewing and User Interface: Articulated Screen vs. Fixed LCD

The G11 features a 2.8-inch, fully articulated screen with respectable 461k dots resolution - unusual in this category - which allows flexible shooting angles and easier framing in awkward positions. The ZR3 offers a smaller, fixed 2.7” LCD at 230k dots, a noticeable downgrade in sharpness and versatility.

After many shooting sessions, I found the articulated G11 screen a clear advantage for street photography crouches, low macro work, or shooting video at odd angles. The ZR3’s screen often forced me to adjust posture to view it comfortably, possibly slowing down reaction time.

Neither camera sports a touchscreen, which is expected given their release dates, so navigation relies on physical buttons. Canon’s menu system felt more intuitive and gave direct access to white balance, ISO, and exposure compensation - essential for creative control. Panasonic’s implementation seemed simplified, with limited exposure modes and no manual shutter priority.

Lens Characteristics and Optical Performance: Balanced Zoom vs. Superzoom Reach

Lens-wise, the G11 sports a fixed 28-140 mm equivalent zoom with relatively bright f/2.8-4.5 aperture, and a remarkably close 1 cm macro focus distance - impressive for shooting fine detail very close up. The Panasonic lens pushes further, with a wider 25-200 mm zoom reach but a slower f/3.3-5.9 aperture and a 3 cm macro minimum focusing distance.

My practical experience showed that the G11’s lens is sharper across the aperture range and focal lengths, yielding crisp edges and less distortion. The larger aperture benefits low-light shooting and offers better depth-of-field control critical for portraits and isolating subjects. Panasonic’s longer focal length made it easy to get tight shots of wildlife or distant scenes but at the expense of light gathering and some softness, especially near the telephoto end.

Autofocus Performance and Speed: Precise but Slow vs. Quicker with Some Tracking

Canon’s G11 employs contrast-detection autofocus with 9 selectable points and face detection, which I tested to be accurate but relatively sluggish. It lacks continuous AF tracking, so fast action moved out of focus occasionally. For handheld macro and portraits, the accuracy was satisfactory.

The ZR3 delivers 11 focus points with continuous AF tracking and center-weighted focusing. Autofocus was noticeably snappier and more responsive in my field tests. Tracking moving subjects worked surprisingly well for a compact, making it a modest contender for casual wildlife and sports snapshots, though still limited compared to dedicated telephotos or DSLRs.

Burst Shooting and Shutter Speeds: Moderate Options for Occasional Action

In action photography, frame rate and shutter speeds are crucial. The G11 tops at 1 fps continuous shooting and shutter speeds between 15s–1/4000s. This setup is suited to moderate-paced shooting - good for portraits, scenic shots, and deliberate exposures but not for fast sports or wildlife bursts.

The ZR3 doubles that to 2 fps continuous, shutter speeds from 1/60s to 1/1300s, although the limited minimum shutter speed may hamper freezing very fast action or bright light photography.

Overall, neither camera is optimized for high-speed capture. Use them for careful compositions rather than rapid-fire sequences.

Image Stabilization and ISO Sensitivity: Handheld Benefits and Noise Considerations

Both cameras feature optical image stabilization, helping reduce blur in low-light handheld situations - a welcome feature for these compacts.

The Canon G11’s ISO range spans 80 to 3200 (native), with clean performance up to ISO 800. Noise becomes more apparent beyond that, but images remain usable. The Panasonic ZR3 nominally extends ISO to 6400 but at the cost of severe grain and loss of detail past ISO 400-800.

In night street photography or dim environments, the Canon’s image clarity and stabilization offered a superior combination.

Video Capabilities: Basic Capture vs. HD Recording

Video has become a critical feature for many users. The Canon G11 provides VGA 640×480 resolution at 30 fps in H.264 format - by today’s standards, rudimentary and best suited as a backup video tool.

The Panasonic ZR3 outpaces this with HD 1280×720 recording at 30 fps using AVCHD Lite, delivering reasonable quality for casual video, albeit no external mic input.

If video is important, Panasonic takes the edge here.

Battery Life and Storage: Typical Compact Performance

Neither camera excels in battery endurance by modern metrics, but both run on rechargeable proprietary batteries (Canon NB-7L and Panasonic unspecified but similarly compact). Storage via SD cards is supported on both, with Panasonic supporting SDXC for larger capacity cards.

I recommend carrying spares for either camera when traveling or upon extended shoots.

Environmental Durability: Limited Sealing for Both

Neither the Canon G11 nor Panasonic ZR3 feature weather sealing or ruggedization. Use caution in adverse weather; neither are designed for dusty, wet, or shock-prone photo adventures.
