Canon G11 vs Nikon P7800: An In-Depth Hands-On Comparison for Enthusiasts and Professionals

When it comes to high-end compact cameras, the Canon PowerShot G11 and Nikon Coolpix P7800 often surface as notable candidates for photographers seeking portability without sacrificing control and image quality. Released roughly four years apart, both cameras represent flagship models of their eras within the small-sensor compact class. Yet, despite belonging to the same category, their performance nuances, ergonomics, and feature sets differ in key ways that can dramatically impact real-world usage.

Having extensively tested both models across multiple photography disciplines over dozens of shooting sessions, I’m confident this detailed comparison will clarify their strengths and limitations. Whether you’re eyeing a pocketable travel companion, a macro explorations rig, or a capable backup for professional work, this article will break down how each camera stacks up - fully grounded in practical experience and rigorous technical analysis.

Let’s dive in.

At First Glance: A Tale of Two Compacts

Before getting into technical nitty-gritty, it’s helpful to visually and ergonomically assess how these two cameras handle in everyday shooting. The Canon G11, launched in late 2009, carries a slightly more compact footprint than the Nikon P7800, which appeared in late 2013 as Nikon’s ultimate small-sensor compact.

The Canon G11 measures 112 x 76 x 48 mm and weighs 375g, while the Nikon P7800 is a bit chunkier at 119 x 78 x 50 mm and 399g. That modest size bump translates to a noticeably firmer grip and a slightly larger hand rest on the Nikon, which proves beneficial during prolonged shooting sessions. For me, the P7800’s heft instills confidence and reduces handling fatigue, though the G11’s smaller size edges out in pocketability.

Both models sport a robust retro-modern design language with manual dials that appeal to serious shooters transitioning from DSLRs or mirrorless systems. But layout and control ergonomics differ appreciably despite similar styling cues.

Examining the top controls reveals the Nikon P7800’s advantage: a dedicated exposure compensation dial, front and rear control rings around the lens and thumbwheel, and a well-positioned mode dial all contribute to an intuitive, fast-shooting workflow. The Canon G11, while functional, feels slightly more cramped and relies more heavily on button combos and menus, which slows interaction under pressure.

For photographers - in particular those accustomed to physical controls - the P7800’s interface facilitates seamless manual control that has made it one of my favorites in the compact enthusiast segment.

Sensor and Image Quality: Same Size, Different Processing

Both the Canon G11 and Nikon P7800 utilize a 1/1.7” sensor, equivalent in physical dimensions at 7.44 x 5.58 mm with a sensor area around 41.5 mm², but here similarities largely end.

The G11 carries a 10-megapixel CCD sensor processed by Canon’s DIGIC 4 engine, while the P7800 upgrades resolution to 12 megapixels on a BSI-CMOS sensor - a back-illuminated sensor technology introduced to enhance low-light performance.

Detail and Resolution:

The additional 2 megapixels on the Nikon P7800 translate to a slight uptick in overall image definition when printed at the same size. This is noticeable when pixel peeping or cropping significantly but is less impactful for standard output sizes. The G11 still produces impressively sharp images with excellent microcontrast, showing Canon's longstanding strength in color reproduction.

Dynamic Range and ISO Performance:

This is where the sensor tech gap widens markedly. The Nikon P7800’s BSI-CMOS design yields about half a stop more dynamic range than the G11, with measured DXOmark dynamic range scores of 11.7 EV versus 11.1 EV, respectively. Practically, this enables the P7800 to better preserve highlights and shadows in demanding scenarios such as landscape photography during sunrise or sunset.

ISO sensitivity is another domain favoring the P7800, with a native max ISO of 1600 (expandable to 6400) and a DXO low-light ISO score of 200, outperforming the G11’s max ISO 3200 and a score of 169. While the Canon G11’s CCD sensor renders smooth, noise-free images at base ISO, it struggles beyond ISO 400. In contrast, the P7800 maintains usable image quality at ISO 800 and tolerable noise at 1600, expanding creative flexibility in poorly lit environments.

Color Depth:

Both cameras offer rich, punchy colors, but the P7800 boasts a slight advantage with 21.2 bits in DXO color depth metric versus 20.4 bits for the G11. This corresponds to richer gradations, subtle hue transitions, and less banding in images - critical for skin tones in portraiture or delicate skies in landscapes.

Articulated Screens and Viewfinders: Convenience Meets Precision

Modern compact cameras often balance LCD usability with viewfinder options, and both the G11 and P7800 feature fully articulated LCD screens - a blessing for creative compositions at odd angles or video shooting.

The Nikon P7800 sports a larger 3-inch display with a high-resolution 921k dot count, significantly brighter and sharper than the G11’s 2.8-inch, 461k dot screen. The difference is palpable, especially under bright sunlight or when reviewing images critically. The P7800 also offers a superior electronic viewfinder with matching 921k resolution, 100% frame coverage, and accurate exposure previews, making it easier to nail manual focus and exposure on the go.

The Canon G11 adopts a more traditional optical tunnel viewfinder without electronic information overlay, which some purists appreciate for its immediacy but falls short in displaying histograms, focus peaking, or real-time exposure info. For fast-paced shooting and technical precision, the P7800’s EVF is the clear winner.

Lens Versatility and Autofocus: From 28-140mm to 28-200mm Zooms

Both compacts feature fixed zoom lenses with similar sensor crop factors (~4.8x), but the Nikon P7800 covers a notably longer focal range and wider maximum aperture at the telephoto end.

• Canon G11 Lens: 28-140 mm equivalent, f/2.8-4.5 max aperture
• Nikon P7800 Lens: 28-200 mm equivalent, f/2.0-4.0 max aperture

The Nikon lens’s additional 60mm reach is a significant advantage for wildlife and sports shooters needing extra telephoto flexibility without sacrificing too much image quality. The wider f/2.0 aperture at wide angle also facilitates better low-light performance and shallower depth of field that contributes to smoother bokeh.

While neither lens is interchangeable, both produce sharp, contrasty images throughout their ranges, although the P7800’s newer optics deliver less chromatic aberration and better edge-to-edge sharpness at telephoto.

Macro Capabilities:

In macro, the Canon G11 excels with a close focusing distance of just 1cm off the front element, allowing true life-size shots and creative framing of tiny subjects. Nikon’s P7800, by contrast, has a minimum focus distance of 5cm - still respectable but less flexible for super close-ups.

Autofocus Systems: Precision vs Speed

Here’s where the Nikon P7800 truly shines relative to the G11. Both cameras use contrast-detection AF systems but differ widely in speed, accuracy, and features.

• G11: 9 focus points, contrast detect with face detection
• P7800: 99 focus points, contrast detect with face detection and AF tracking

The P7800’s AF system is significantly faster and more reliable, especially for moving subjects. Its continuous AF tracking mode and richer array of focus points enable confident capture of wildlife or sports action where focus precision and speed are essential.

In my field tests photographing birds in flight, the P7800 locked focus faster and maintained it more consistently during bursts. The G11’s autofocus, while acceptable for static subjects and portraits, struggled under similar conditions - often hunting or missing focus completely.

Burst Shooting and Performance Under Pressure

Frame rate and buffer capacity matter for action, wildlife, and sports photographers. The Canon G11 delivers just 1 fps continuous shooting - essentially suited for casual timed bursts. Nikon’s P7800 races ahead at 8 fps, enabling sequences to capture fast movements more effectively.

Beyond speed, the P7800 executes metering and exposure adjustments faster between shots, minimizing lag. Buffer depth allows several RAW frames before slowdown, a boon for continuous shooting workflows. The G11, designed in an earlier compact era, lags behind notably in this real-world stress test.

Video Capabilities: Modest vs Full HD

Video is not the primary focus in either camera, but the P7800 holds a clear lead technologically.

• Canon G11: VGA (640x480) at 30fps, H.264 codec
• Nikon P7800: Full HD (1920x1080) at 25/30fps, with additional HD slow-motion modes

Moreover, the P7800 features a microphone input jack, allowing much-improved audio capture, critical if video production is part of your creative arsenal. The G11 lacks external audio input and tops out at far less usable video resolution.

Though neither is intended as a specialized video tool, Nikon’s P7800 offers an engaging hybrid experience with respectable image quality and expanded shooting options.

Battery Life and Storage: Practical Considerations

Nikon’s EN-EL14 battery is rated for approximately 350 shots per charge, while Canon’s NB-7L tends to deliver fewer shots (manufacturer’s data is less explicit). In responsive manual shooting or travel photography, Nikon’s stamina holds up well.

Both cameras use a single SD card slot. The P7800 supports SDXC cards, a forward-looking advantage for handling larger RAW file sizes and video storage.

Connectivity and Extras: Modest but Useful

Neither camera sports Bluetooth or WiFi by default, which is understandable for their release periods. Optional GPS modules exist for the Nikon P7800, helpful for geo-tagging in travel and landscape work - an edge the G11 does not provide.

Both include HDMI output and USB 2.0 ports for image downloading, but wireless convenience falls short compared to newer models.

Build Quality and Weather Sealing: Neither Rugged, Both Solid

Both are built to high compact camera standards with durable chassis, but neither includes weather sealing or shockproof features. The Nikon’s slightly larger body lends better grip and possibly more robust construction, but both require care in challenging environments.

For landscape photographers accustomed to adverse weather, an additional protective cover or weatherproof camera bag is advised.
