First Impressions: How Do These Cameras Feel in Your Hands?

Before diving into specs, understanding a camera’s physicality is paramount. How a camera sits in your hand impacts your shooting comfort, especially during prolonged sessions or travel. Let’s start there.

At a glance, the Nikon S3600 and S640 share the compact, pocket-friendly ethos Nikon targets with this line. The S3600 measures 97 x 58 x 20 mm and weighs just 125 grams, making it slightly larger yet lighter than the S640’s 91 x 55 x 21 mm and 130 grams. The differences are subtle but noticeable in hand:

• Nikon S3600: Slimmer profile and rounded edges lend a contemporary look and slightly more grip-friendly form.
• Nikon S640: More angular design with a bit more heft, which some may associate with solidity but could impact portability over long shoots.

Both cameras lack a dedicated viewfinder, relying entirely on rear LCD screens. Neither features a touchscreen interface - a limiting factor for quick adjustments but typical for their era.

Ergonomically, both fall short in manual control options, reflecting their intended audience: casual shooters and beginners. Their compact sizes favor travel, street photography, or casual portraits, but you’ll likely depend on auto modes and basic settings.

Top-Down: Reviewing Button Layout and Handling Ease

Handling extends beyond size - control placement and intuitive button arrays streamline photography workflows.

Key takeaways from handling the top decks:

• Nikon S3600: Offers a well-spaced shutter release and zoom rocker, along with a power button. Its simplicity reduces potential confusion but limits flexibility.
• Nikon S640: Slightly more control real estate including an exposure mode dial (though only for auto or scene modes), but no priority or manual modes.

Neither camera supports fully manual exposure, aperture priority, or shutter priority. Both operate mostly in fully automatic or scene presets with minimal customization available. For photographers wanting creative control, this is a significant compromise.

Sensor Technology & Image Quality: The Heart of the Matter

When comparing image quality, sensor attributes and processing become critical. Both cameras use small 1/2.3-inch CCD sensors - a typical size for compact cameras - but differ in resolution and ISO capabilities.

Observations:

• The S3600’s 20MP sensor offers significantly higher resolution, allowing for larger prints and more cropping freedom. However, the quality depends heavily on sensor noise control.
• The S640’s 12MP sensor provides a lower resolution but theoretically could offer better noise performance, thanks in part to a higher maximum ISO rating (6400 vs 3200) and the Expeed processing engine.

Real-World Image Quality:

In practice, both CCD sensors perform similarly, producing sharp images with good color fidelity in well-lit conditions. But CCD technology generally struggles at high ISO compared to modern CMOS sensors, resulting in noticeable noise beyond ISO 400–800.

The S3600’s higher megapixel count may lead to visible grain when images are enlarged, though it excels in daylight scenarios like landscapes and portraits. The S640, with its slightly superior ISO ceiling, fares better in low-light situations but sacrifices resolution.

Neither camera saves RAW files, limiting post-processing flexibility for photographers who like to tweak their shots extensively.

Viewing and Interface: How You Compose Your Shots

Both cameras rely on 2.7” fixed TFT LCD screens with 230k dot resolution - understandable for their entry-level compact status but below today’s standards.

• The display on the S3600 has an anti-reflection coating, improving visibility under bright sunlight - a definite usability plus for outdoor shooting.
• The S640 screen is more basic and lacks this enhanced viewing feature, sometimes complicating composition outdoors.

Neither camera features a touch interface or an electronic viewfinder, which can challenge precision framing, especially in bright environments when LCD visibility is compromised.

Autofocus Systems: Speed and Accuracy in Real-World Conditions

Autofocus dramatically influences your photo success, especially when capturing moving subjects.

The S3600’s AF array includes 99 points with face detection, a helpful feature when shooting portraits or casual group shots. Continuous AF and tracking enhance success for moving subjects - a rarity among cameras of this category.

Conversely, the older S640 relies on a simpler AF system without face detection or continuous tracking. It only supports single AF mode, making it less adept at focusing on moving subjects.

In testing, the S3600 acquitted itself well for casual portraits and street photography, locking onto faces reliably under ideal lighting. The S640 required more deliberate focus attempts and was slower to react.

Lens and Zoom: Flexibility for Different Compositions

Both cameras feature fixed lenses with optical zoom, but focal ranges differ markedly.

Key Insights:

• The S3600 offers more zoom reach (8x vs 5x), making it better suited for distant subjects like wildlife or candid street shots.
• The S640 benefits from a faster lens at wide angle (f/2.7 vs f/3.7), facilitating better low-light performance and shallower depth of field at the short end.
• Both cameras share impressive close focus distances ideal for casual macro shots down to 2 cm.

While neither lens supports interchangeable optics (fixed lens system), the S3600’s extended zoom versatility makes it a more capable generalist.

Shooting Modes and Special Features

Neither model offers advanced modes like aperture priority or shutter priority - standard for truly creative control. Instead, their scene modes cater to beginners:

• Nikon S3600: Includes face detection, continuous AF, exposure compensation not supported, but has custom white balance.
• Nikon S640: No face detection, no custom white balance.

Neither supports RAW capture or focus stacking/bracketing.

Burst Shooting and Video Capabilities: For Action and Motion

Neither camera is tailored for action photography given the slow burst rate - S3600 manages just 1 frame per second, while the S640 does not specify continuous shooting.

Video capture is limited to HD 720p at 30fps, sufficient for casual clips but not suitable for professional video content creation. Lack of microphone inputs and basic codec support further constrain video creativity.

Battery Life and Storage Options

• Nikon S3600: Uses rechargeable EN-EL19 battery delivering around 230 shots per charge.
• Nikon S640: Uses EN-EL12 battery; official battery life not listed but generally similar to S3600.

Both accept SD/SDHC/SDXC cards but the S640 also includes limited internal storage.

Connectivity and Extras

Neither camera sports modern connectivity options such as Wi-Fi, NFC, or Bluetooth, limiting ease of image transfer and remote control - a significant point for content creators who prioritize seamless sharing.

Both feature built-in flashes with modest range (S3600 rated to 3.5m, S640 unspecified), adequate for casual indoor shooting but inferior to external flash setups or more advanced compacts.

Price and Value Analysis

Both models are budget compacts, occasionally available at discounted prices used or refurbished.

In terms of value, the S3600’s higher megapixel count, improved autofocus features, and longer zoom justify its slight price advantage for most casual users.
