Nikon AW120 vs Nikon S640: An Expert’s In-Depth Comparison of Two Compact Cameras

When Nikon releases a compact camera, it almost always brings unique strengths to the table. Today, I’m diving into a head-to-head comparison between two intriguing models in Nikon’s lineup from the past decade: the Nikon Coolpix AW120 (announced in early 2014) and the Nikon Coolpix S640 (released in mid-2009). Both are compact cameras, but they target somewhat different user priorities: ruggedness and versatility versus sleek portability and simplicity. Over years of hands-on testing and image analysis, I’ve developed a framework for evaluating cameras like these through the lens of practical use cases, sensor tech, handling, and real-world imaging performance.

If you’re a photography enthusiast considering either model - or just interested in how Nikon approached compact cameras in these eras - this comprehensive review will break down their features, strengths, and trade-offs. We’ll cover everything from sensor performance and autofocus to video features and durability. Along the way, I’ll share insights from lab tests, field experience, and detailed image comparisons.

Let’s get started with a quick look at the physical differences.

Built for Adventure vs Built for Portability: Handling and Ergonomics

Right off the bat, the most obvious difference is the AW120’s ruggedness compared to the S640’s slim, pocket-friendly design.

The Nikon AW120 is a tough cookie. Measuring 110x66x26mm and weighing 213 grams, it’s built to endure. Its environmental sealing includes waterproof (up to 15m), freezeproof (down to -10°C), dustproof, and shockproof features. That means you can confidently take it on hikes, beach trips, ski runs, or even underwater snorkeling adventures without a bulky housing. The grip is contoured for a secure hold even in wet conditions, and the buttons have a firm but responsive feel, designed to work with gloves.

In contrast, the Nikon S640 is a classic small-sensor compact - compact (91x55x21mm) and very light (130 grams). It’s far more pocketable and discreet, with a minimalist style emphasizing portability and ease-of-use. However, it lacks environmental sealing, making it more prone to damage if exposed to harsh elements or accidental drops. Its flat, glossy body and smaller grip surface make prolonged one-handed shooting a less confident experience compared to the AW120.

Inspecting the control layouts also reveals their different priorities:

The AW120 features a rugged, tactile button setup optimized for quick access, including a clearly marked GPS button reflecting its outdoor adventure focus. The S640 has a simpler top plate, with fewer controls, relying on menu navigation - typical for cameras of its class and era.

Overall, if you want a camera that doubles as an all-weather companion, the AW120 wins hands down. For everyday casual shooting where size and discretion are king, the S640 will feel more comfortable.

Sensor Technology and Image Quality: CMOS vs CCD and Megapixels Matter

The heart of any camera’s imaging capability lies in its sensor and processor. Nikon equipped these two cameras with different sensor types and resolutions, reflecting their target uses and development times.

• Nikon AW120: 1/2.3” CMOS sensor, 16 MP resolution (4608x3456 max), with an anti-aliasing filter
• Nikon S640: 1/2.3” CCD sensor, 12 MP resolution (4000x3000 max), also with anti-aliasing filter

The AW120’s CMOS sensor generally offers better high ISO performance and faster readout speeds, which can translate into improved low-light shooting and video capabilities. CMOS also tends to consume less power, assisting battery life. The 16MP resolution enables capturing more detail, particularly beneficial for cropping or making larger prints.

On the other hand, the S640’s CCD sensor was more common in compacts from the late 2000s. CCDs are lauded for generally rendering colors with pleasing accuracy, especially in controlled lighting. Its 12 MP resolution is sufficient (4000x3000 pixels) but limits max enlargement and fine detail capture compared to the AW120.

In side-by-side image comparisons taken in daylight, the AW120's images show superior sharpness and better retention of fine textures, like foliage or fabric weave. The S640’s images display a slightly softer character, which can be viewed as either charming or disappointing depending on your aesthetic preference.

When pushing ISO sensitivity, the AW120 maintains usable images up to ISO 800-1600, whereas the S640’s noise becomes clearly obtrusive beyond ISO 400 - a limitation of its older CCD sensor and noisier amplification. This is significant for low light and indoor photography, where a more modern CMOS sensor offers a clear real-world advantage.

Neither camera supports RAW capture, meaning post-processing flexibility is limited - common for compact point-and-shoot models of their time. JPEG output quality in both cameras is decent but leans on the strength of in-camera processing.

LCD Screen and Interface: Touchscreen No But Ergonomics Matter

Screen quality and usability affect how a camera feels in the hand and how easy it is to frame and review shots. Here is what you can expect from each model.

The AW120 boasts a 3-inch 921k-dot OLED screen, offering bright and vivid colors, good contrast, and excellent viewing angles outdoors. This robust display greatly assists framing underwater or in bright sunlight - the very scenarios the camera encourages. Although it’s a fixed screen with no touchscreen functionality, the excellent color fidelity and response speed improve the user experience tremendously over older LCDs.

Conversely, the S640 features a smaller 2.7-inch LCD with only 230k-dot resolution - a noticeable step below modern standards even at its time of release. Colors look somewhat muted, and glare can become an issue in direct sunlight. No touch input here either, so navigation relies on traditional buttons and menus.

From hands-on testing, the AW120’s screen offers a more pleasant and reliable interface for composing shots, especially when moving fast outdoors or underwater. For casual travel shooting in shaded environments, the S640’s screen still does the job, but it lacks the crispness of its counterpart.

Autofocus Systems and Speed: Tracking vs Simple Spot

Autofocus can make or break your shooting experience, especially in dynamic situations like sports, wildlife, or street photography.

• AW120 Autofocus: Contrast-detection AF with face and eye detection, center-weighted AF area, with AF tracking capabilities.
• S640 Autofocus: Simple contrast-detection AF without face or eye detection, single-point AF only.

I’ve found the AW120’s AF system far more versatile and capable. The inclusion of face detection and AF tracking means it can lock onto subjects more quickly and hold focus better during movement - particularly useful when shooting kids, pets, or wildlife at varying distances.

The S640’s AF performance is adequate for static subjects and casual snapshot use but tends to hunt more in low light or on moving subjects. Its lack of tracking modes limits its use in action or street shooting scenarios.

Neither camera offers manual focus control, consistent with their compact categories, but the AW120’s AF speed is noticeably faster, especially in daylight. Continuous autofocus during video is available on AW120, helping maintain sharpness on moving subjects, unlike the S640.

Lens Performance: Versatility and Aperture Range

Both cameras come with fixed, non-interchangeable 5x zoom lenses, but their focal lengths and apertures vary slightly.

• AW120: 24-120mm equivalent focal length, f/2.8 to f/4.9 aperture range
• S640: 28-140mm equivalent focal length, f/2.7 to f/6.6 aperture range

The AW120’s starting focal length at 24mm wide angle is better suited to landscapes, interiors, and group shots. The S640 starts slightly narrower at 28mm, which is decent but less expansive for environmental portraits or architecture.

More importantly, the AW120 maintains brighter maximum apertures throughout much of the zoom range, especially at the telephoto end. A max aperture of f/4.9 at 120mm beats the S640’s f/6.6 at 140mm, allowing for better low-light performance and some subject isolation ability.

For macro photography, the AW120 outperforms with a closer minimum focus distance of just 1cm, allowing tighter close-ups. The S640 sits at 2cm minimum focus, still respectable but less flexible for fine detail work.

Image stabilization on both models is optical and effective, enabling sharper shots at slow shutter speeds or longer zooms.

Durability and Environmental Features: The AW120’s Unique Selling Point

If durability and adventure-ready features matter to you - for hiking, travel, or rough shooting conditions - the AW120 is in a class of its own compared to the S640.

The AW120’s waterproof rating of 15 meters, freezeproof capabilities to -10°C, and shockproof/dustproof certifications make it a serious contender for anyone wanting a camera that doubles as a rugged companion. It has built-in GPS for geotagging and wireless connectivity, which adds convenience in the field.

The S640 offers no such environmental protections or GPS, making it more suitable for casual, everyday use in controlled environments.

Video Capabilities: Full HD vs 720p - Big Era Gap

Video recording has become an essential feature in even entry-level cameras. Comparing these two cameras’ video specs shows the technological evolution over their release gap.

• AW120: Full HD 1080p (1920x1080) video at 30fps, MPEG-4 and H.264 codecs, optical image stabilization active during video, built-in mic (mono), no external mic input.
• S640: Maximum HD 720p at 30fps (1280x720), Motion JPEG codec, no image stabilization during video, built-in mic only, no mic input.

The AW120’s ability to shoot full HD video with stabilization results in noticeably smoother footage, especially when handheld or moving. The H.264 codec is more efficient and produces better quality per megabyte than the older Motion JPEG used by the S640.

Neither camera has a microphone jack or headphone output, a limitation for more serious video creators.

Battery Life and Storage: Practical Considerations

In field conditions, battery life and storage options matter more than specs sheets.

Both cameras use the same battery model (EN-EL12), but the AW120’s battery life is rated at approximately 350 shots per charge, which is decent given its power-hungry GPS and LCD. The S640’s battery life is unspecified, though real-world tests suggest somewhat shorter duration, partly due to older battery tech and CCD sensor consumption.

Each supports SD and SDHC cards, with one card slot and no internal memory on the AW120, but the S640 has some limited internal storage, which might bail you out in a pinch.

Real-World Sample Images: The Proof is in the Pixels

Seeing is believing, so I compiled side-by-side images shot in various scenarios: daylight landscape, indoor portrait, macro close-up, and low-light street scenes.

The Nikon AW120 consistently delivers sharper, cleaner images with more saturated, pleasing colors and better detail retention. Its higher resolution and advanced CMOS sensor make a decisive difference, especially in mixed lighting.

The S640 produces softer results with lower contrast and muted colors. It does render pleasant skin tones indoors, but struggles with dynamic range, losing highlight and shadow detail more readily.

Overall Performance Ratings and Scoring

Using a standardized evaluation framework weighing sensor image quality, autofocus capability, build, handling, video, and feature set:

• AW120: Scores higher overall, led by image quality, toughness, and video functionality.
• S640: Scores reasonably but lags behind in most categories except size and weight.
