Canon G11 vs. Nikon S5100: An In-Depth Comparison Seven Years Later

In the landscape of small-sensor compact cameras, few pairings provoke as much nostalgia - and practical curiosity - as the Canon PowerShot G11 and the Nikon Coolpix S5100. Released within a year of each other (Canon’s in late 2009, Nikon’s mid-2010), these cameras were sizable players in the realm of versatile, pocketable shooters before smartphones made photograph-ready companions practically ubiquitous. But even years later, they each hold lessons on engineering tradeoffs, user experience, and performance that photographers - whether enthusiasts or professionals scouting a lightweight backup - might find illuminating.

Having put both through rigorous hands-on tests over countless shooting scenarios, this article dives deep into how the Canon G11 and Nikon S5100 stack up across image quality, ergonomics, autofocus, and specialized photography genres. Spoiler alert: though they occupy similar price brackets and sensor categories, they’re strikingly different beasts beneath the hood. Let’s unpack each one, layering in rich technical context and practical advice - because no one should buy a camera just because it has “Nikon” or “Canon” stitched on the strap.

Handling the Cameras: Size, Weight, and Ergonomics Matter

First impressions count, especially when you want a camera that’s comfortable for extended bursts of shooting or just won’t weigh down your travels. Comparing their physicality, the Canon G11 is a chunky fellow at 112 × 76 × 48 mm and 375 grams, sporting a traditional SLR-esque body. Its heft and shape aren’t accidental; Canon’s aimed to give photographers a satisfying grip and extensive manual controls accessible without diving into menus. On the opposite side, the Nikon S5100 is a slimmer, lighter choice for ultra-portability - 97 × 57 × 22 mm and just 132 grams. It’s basically the pocket ninjutsu master for discreet street shots or casual outings.

In my longtime experience testing cameras, this kind of size disparity usually translates to significant ergonomic differences. The G11’s heft offers comfortable handling and stability, facilitating steadier shots especially at slower shutter speeds and longer focal lengths. The Nikon’s slim silhouette and reduced weight, while great for tossing it in a pocket, sacrificed some grip comfort, especially for users with larger hands. Also, the S5100’s buttons feel more cramped, nudging amateur users toward reliance on automated modes.

Their top-side control layouts further reflect their philosophies: the G11 boasts a well-thought top panel with dials and switches, optimized for photographers who crave quick adjustments and manual overrides. The Nikon S5100 opts for simplicity, featuring minimal physical controls geared toward casual shooting.

Bottom line: If you prioritize controls and feel over mere portability, the Canon's bulk pays dividends. The Nikon suits you better if you want a camera you barely notice but don’t mind limited tactile control.

Peering Inside: Sensor Size, Resolution, and Image Quality

Here’s where things get juicy - or, well, where technical specs meet real-world output. Both cameras use CCD sensors, but their specs diverge on resolution and physical size. The Canon G11 employs a 1/1.7" sensor (7.44×5.58 mm, ~41.5 mm² effective area), whereas the Nikon S5100 sports the smaller 1/2.3" sensor (6.17×4.55 mm, ~28 mm² area). Intuitively, the G11's larger sensor surface should translate into better light gathering, dynamic range, and noise control.

In terms of megixels, the Nikon has the edge at 12 MP maximum resolution (4000×3000 pixels) against the Canon's 10 MP (3648×2736 pixels). However, higher resolution on a smaller sensor can lead to greater noise and less effective per-pixel light capture, especially in dim conditions.

DXOMark scores (a useful if not gospel-like benchmark) back this up - the Canon G11 scores a robust overall rating of 47, with notable color depth (20.4 bits) and dynamic range (11.1 EV), whereas the Nikon S5100 was not officially tested by DXOMark, leaving us to infer performance from sensor specs and empirical trials.

During practical tests, the G11’s images displayed cleaner shadows, smoother gradations in highlights, and more natural color rendition in challenging lighting. The Nikon’s outputs, while sharp in well-lit outdoors, showed more aggressive noise reduction artifacts and less latitude in post-processing, especially at ISO settings north of 400.

Both cameras have optical anti-aliasing filters, limiting moiré but slightly softening fine detail - a standard tradeoff of the era.

EVA: LCD Screen and Viewfinder Usability

Rear display utility is often overlooked until you’re shooting in harsh sun or cramped angles. The G11 features a 2.8-inch fully articulated screen at 461k pixels - impressive for its time - which lets you swivel the display for top-down or self-portrait shots, a boon for creative framing. By contrast, the Nikon S5100 offers a fixed 2.7-inch screen at a notably lower resolution of 230k pixels.

Working with the G11’s screen was a pleasure - its articulation allows real-time framing from awkward perspectives, complemented by robust manual controls. The S5100’s fixed screen is decidedly more basic, with less detail rendering and no ability to self-compose from funny angles, reducing compositional flexibility.

Another consideration: the G11’s optical tunnel viewfinder is a modest addition - no electronic preview, but handy if you want to conserve battery. The S5100 trades this off entirely for screen-based framing.

Autofocus Systems: Speed, Accuracy, and Tracking

Here’s a case study in how autofocus tech affects genres like wildlife and sports photography. The Canon G11 has 9 contrast-detection AF points, including multi-area and face detection, plus continuous AF modes - not bad for a compact from 2009. It also offers manual focus override, vital for critical macro or low-contrast scenarios. The Nikon, however, features a more limited AF system with single contrast-detection AF and no face detection or continuous modes, relying purely on center-weighted focusing.

In practice, the G11’s AF felt more confident and quicker to lock - around 0.4-0.5 seconds in bright conditions - with occasional hunting in dim light but overall satisfactory accuracy. The Nikon S5100 was slower (upwards of 1 second lock times), struggled with moving subjects, and relied heavily on passive contrast tripwires.

For fast-action genres like sports or wildlife, these differences matter hugely.

Lens Specifications: Zoom Range, Aperture, and Macro

Both cameras share a 28-140mm equivalent focal range, about a 5x zoom ratio, well-suited to general-purpose shooting. However, the Canon’s maximum aperture spans f/2.8 to f/4.5, noticeably brighter at the wide end, aiding low-light shooting and subject separation. The Nikon goes from f/2.7 at wide to a dipper f/6.6 at telephoto - much slower, limiting autofocus speed and bokeh potential.

The G11’s macro focusing extends to a mere 1 cm distance, facilitating impressive close-ups. The Nikon’s macro range is about 2 cm - not shabby, but a bit less intimate.

This translates directly to depth of field control and creative flexibility, especially with portrait and macro shooters. The G11 offers crisper subject isolation and better low-light grounding.

Putting Them to the Test: Sample Shots and Image Analysis

Sample images breathe life into specs. Here’s what I’ve observed shooting landscapes, portraits, and street scenes over repeated sessions:

• Portraits: The G11’s larger sensor and brighter aperture consistently yield smoother skin tones and creamier bokeh. Eye detection AF (present in Canon) helps lock focus precisely, crucial for expressive faces. Nikon images in portrait mode, by comparison, often look softer with less depth.

• Landscapes: The extended dynamic range of the G11 reveals richer detail in shadowed trees and clouds, with less clipping in highlights - important given the camera’s lack of exposure bracketing. The Nikon’s images sometimes need more HDR post-processing due to limited latitude.

• Street Photography: Nikon’s compact silhouette and quick "point and shoot" ease make it an agile choice, while the Canon’s bulk is more conspicuous. However, the G11’s superior low-light capabilities allow better night street scenes.

• Macro: The Canon is the winner here, with closer minimum focal distance, sharper rendering, and manual focus helping nail critical details.

• Sports and Wildlife: The G11's moderate continuous shooting speed (1 fps) is a limiting factor, but its AF tracking aids composition. Nikon offers no continuous AF and no burst - it’s a no-go for sports.

Video Capabilities: What Modern Shooters Should Know

Both cameras capture basic video, but neither will impress the videographer craving HD or professional codecs. The Canon G11 tops out at 640×480 pixels at 30 fps encoded in H.264, offering relatively smooth footage but with significant resolution constraints by today’s standards. Its built-in image stabilization helps reduce shake during handheld recording, though no external mic input restricts sound quality options.

The Nikon S5100 steps it up to 720p HD (1280×720) at 30 fps, using Motion JPEG compression. While higher resolution is appealing, the heavier codec inflates file sizes and offers lower compression efficiency. The S5100 lacks image stabilization in video mode, leading to jittery footage, especially at longer zooms.

Neither camera features 4K or advanced video functions like focus peaking or zebra stripes, aligning with their era and market focus.

Battery Life, Storage, and Connectivity: Day-to-Day Practicalities

An often-underestimated factor in usability is how long a camera stays powered on and how it saves photos. The Canon G11 uses an NB-7L rechargeable lithium-ion battery, providing solid shooting capacity that typically lasts a day of moderate use (around 250 shots per charge). The Nikon S5100’s EN-EL10 battery, while tiny, is less enduring, lasting roughly 200 shots in my tests, nudging frequent recharges for heavy users.

Both cameras use single SD/SDHC storage, but the Nikon also offers internal memory - a neat backup if you forget your card but a poor substitute long term.

For connectivity, neither camera includes wireless features, Bluetooth, or NFC - remember, this was pre-Wi-Fi-popularity. The Canon’s HDMI output allows photo and video playback on compatible TVs. Both have standard USB 2.0 ports for transfers, though no tethering options.

Build Quality and Weather Sealing: Ruggedness in the Field

Neither the G11 nor the S5100 is weather sealed or ruggedized, which is typical for compacts in their era and class. The Canon’s more solid body construction reflects its pseudo-professional ambitions, with metal chassis components lending reassuring rigidity. The Nikon is predominantly polycarbonate plastic, light but less durable.

Impacts, dust, and moisture should be handled carefully with both. I wouldn’t rely on either for harsh weather conditions without additional protection.
