Nikon Coolpix P7700 vs S5100: A Thorough Comparison for the Discerning Photographer

As someone who has tested hundreds of compact cameras over the past 15 years, I always enjoy delving into the nuanced performance differences between models that share the same brand but arrive with very different design philosophies. Today, I'm putting Nikon’s Coolpix P7700 head-to-head against its smaller sibling, the Coolpix S5100. Both appeal to enthusiasts and entry-level shooters seeking portability and decent image quality, yet they inhabit quite distinct niches. In this detailed review, I'll unpack how these cameras stack up across photography genres, real-world handling, and technical chops, based on rigorous hands-on experience. Moreover, I’ll help you understand which camera truly earns your money and matches your photographic ambitions.

First Impressions: Size, Handling, and Design

When held side-by-side, my immediate takeaway is the contrast in physical presence. The Nikon P7700 is noticeably larger, thicker, and heftier at 392 grams and dimensions of 119 x 73 x 50 mm. It’s a compact but chunky enthusiast’s camera, designed to offer control and flexibility reminiscent of DSLR ergonomics, including a robust grip. By contrast, the S5100 is ultra-compact - just 132 grams and 97 x 57 x 22 mm - fitting easily into a jacket pocket or small purse. The trade-off here is clear: the P7700 favors manual interaction and durability, while the S5100 emphasizes portability and casual use.

Examining the control layouts reveals why. The P7700 features dedicated dials for shutter speed and exposure compensation, a mode dial, customizable buttons, and a clickable 3-inch fully articulated LCD with 921k-dot resolution. This design appeals to photographers who want speedy access to manual exposure settings and flexible shooting angles, such as low or high perspective close-ups. The S5100’s fixed 2.7-inch screen has a considerably lower resolution of 230k dots, no articulating movement, and minimal physical controls, relying heavily on menu navigation and auto modes. Its simplicity is excellent for beginners or those who prefer a snapshot experience but limits creative responsiveness.

Sensor and Image Quality: The Heart of the Matter

Digging under the hood, the sensor is where these cameras differ fundamentally. The Nikon P7700 houses a 1/1.7-inch backside-illuminated CMOS sensor measuring 7.44 x 5.58 mm (~41.5 mm² area) with 12 megapixels, offering enhanced light gathering and lower noise compared to older technology. Conversely, the S5100 uses a smaller 1/2.3-inch CCD sensor at 6.17 x 4.55 mm (~28 mm²) but with the same 12-megapixel count. CCD sensors, common in earlier compact cameras, generally lag CMOS sensors in noise performance and dynamic range, particularly in low light.

The P7700 scores significantly better in DxOMark tests - 53 overall versus the untested S5100 sensor - especially in color depth (21.1 bits vs lower) and dynamic range (11.7 EV), which translates to punchier, more nuanced images with better highlight and shadow detail retention. My side-by-side shootouts reinforce this, especially when capturing high-contrast scenes such as landscapes at dawn or portraits with complex lighting. The S5100’s images look flatter and noisier when pushed beyond ISO 400, whereas the P7700 remains usable up to ISO 1600 with manageable fine grain.

Autofocus and Focusing Systems in Action

If you’re familiar with my testing methods, you know I emphasize autofocus speed and accuracy under realistic shooting conditions. The Nikon P7700 utilizes a contrast-detection AF system with 99 focus points, including face detection and center-weighted AF modes, plus continuous AF tracking which helps in capturing moving subjects. It even offers selective AF via the customizable control ring around the lens - a boon for precise adjustments. Conversely, the S5100 simplifies AF to single-point contrast detection with no face or tracking aid, making it less reliable for anything beyond static subjects.

In portrait sessions, for instance, the P7700’s eye-detection and tracking capabilities contribute to consistently sharp focus on eyes, a critical feature when shooting tight headshots. The S5100, lacking such sophistication, often hunts or locks focus slower, resulting in missed moments especially in spontaneous shooting.

Lens and Zoom Range: Flexibility vs Convenience

The fixed lens on the P7700 covers a versatile 28-200mm equivalent zoom (7.1x), with bright apertures from f/2.0 at wide-angle to f/4.0 at telephoto. This allows decent low-light performance and good subject isolation thanks to shallow depth-of-field opportunities at 28mm f/2. In contrast, the S5100’s lens offers a 28-140mm equivalent range (5x zoom) with a slower f/2.7-6.6 aperture range, limiting its low-light prowess and ability to blur backgrounds effectively.

From my experience shooting wildlife or sports with the P7700, the extended telephoto reach combined with stabilizer support helps frame distant subjects clearly. The S5100’s slow lens is far less versatile here, better suited to casual travel snaps or indoor portraits with ample lighting.

Performance Across Photography Genres

Portrait Photography

The P7700 shines with accurate skin tone reproduction, reliable face detection, and smooth bokeh rendering due to its bright aperture and larger sensor. I found that in natural light, the skin tones appeared natural and pleasing without much post-processing needed. The versatile zoom and manual focus lets you fine-tune framing and depth-of-field, elevating portraiture beyond the casual snapshot. The S5100’s flatter sensor and slower lens limit creative bokeh and often render portraits as softer, less detailed, and less vibrant.

Landscape Photography

Dynamic range is vital here, and the P7700’s sensor delivers superior highlight preservation and shadow detail. Additionally, its RAW support facilitates detailed post-processing enhancements - a feature strictly absent on the S5100. Landscape shooters will appreciate the P7700’s rugged build and articulated screen, ideal for tricky angles and tripod usage. The smaller sensor and limited dynamic range of the S5100 manifest in muted skies and poorer tonal gradations in challenging lighting.

Wildlife and Sports Photography

For fast-action capture, the P7700’s 8 frames per second burst mode and contrast AF tracking outperform the S5100’s lack of continuous shooting modes. While neither is a professional-grade sports camera, in my tests the P7700 managed to hold focus better on erratic bird flight or children’s games in moderate light. The extended zoom helps bring distant subjects closer without degrading image quality. The S5100’s sluggish response and shorter zoom result in missed or blurry shots in these demanding scenarios.

Street Photography

Street photography benefits from discretion and portability. The S5100 is the lighter, more pocketable option, making it unobtrusive for candid shooting and quick point-and-shoot operation. Nonetheless, its slower AF and simpler sensor performance can frustrate rapid spontaneous captures in low or mixed lighting. The P7700, though bulkier, offers the advantage of manual controls and customizable focus, rewarding thoughtful street photographers willing to carry the extra weight.

Macro Photography

Both cameras can focus as close as 2 cm, facilitating interesting macro shots of flowers or small objects. The P7700’s sharper lens, manual focus ring, and stabilization better support precise close-up framing and sharpness. The S5100’s fixed autofocus and slower lens yield softer detail, especially in dim environments. I often found the P7700 more enjoyable for this genre, especially handheld.

Night and Astro Photography

Here, the P7700’s superior sensor noise characteristics, ISO performance up to 1600, and manual exposure control enable impressive handheld and tripod night shots. The longer minimum shutter speed of 60 seconds allows for effective long exposures, ideal for star trails and cityscapes after dark. The S5100 falls short with a limited maximum shutter speed of 1.5 seconds and high noise at ISO beyond 400, restricting its utility for night photography.

Video Capabilities

The P7700 offers Full HD 1080p recording at up to 30fps with advanced H.264 encoding, optical image stabilization, and a microphone port supporting external mics for clear audio capture. The articulated screen aids in framing creative angles while filming. In contrast, the S5100 maxes out at 720p and uses older Motion JPEG compression, producing larger files with lower quality. It lacks any microphone input and stabilization during video, limiting its usefulness for serious video work.

Build Quality, Weather Sealing, and Durability

Neither camera is weather sealed or ruggedized. However, the P7700 exhibits a more solid build, feeling robust and well finished with metal body components. The S5100’s plastic construction is lighter but less durable, suitable for casual pocket use but not demanding environments.

Ergonomics and User Interface

The P7700’s more traditional DSLR-style layout, tactile dials, control ring, and illuminated buttons shine in real-world use, especially when rapid adjustments are necessary. The fully articulated screen adds compositional flexibility. The S5100’s minimal buttons and menu-driven control reduce complexity but constrain advanced photography techniques.

Battery Life and Storage

The P7700 uses the EN-EL14 battery rated for about 330 shots per charge, which held up well during my day-long outings with mixed shooting. The S5100 employs the EN-EL10 battery with unspecified life but generally inferior runtime due to smaller capacity. Both cameras support SD/SDHC/SDXC cards, with single card slots. Storage options are standard but sufficient.

Connectivity and Extras

Neither camera includes wireless features like Wi-Fi or Bluetooth - unsurprising given their release eras. The P7700 adds HDMI output, USB 2.0, and optional GPS, faxing in support for tethered or external display use. The S5100 lacks HDMI or GPS support and similarly offers USB 2.0.
