Nikon Coolpix S3300 vs Nikon Coolpix S640: An In-Depth Compact Camera Showdown

As someone who has spent over 15 years scrutinizing digital cameras from the ground up, picking apart sensor nuances, autofocus systems, and real-world usability, I’m always intrigued by compact cameras. These pocket-sized wizards often deliver surprising versatility despite their small footprints - and they’re typically the first cameras novice enthusiasts consider before stepping up to larger systems. Today, we’re placing two Nikon compacts side-by-side: the Nikon Coolpix S3300 and the Nikon Coolpix S640. Though both hail from Nikon’s highly regarded Coolpix line and serve as affordable entry-level options, they offer distinct experiences shaped by the technology and design decisions of their respective eras.

Through this extensive comparison, I’ll dive into every aspect from size and handling to sensor technology, imaging prowess, autofocus behavior, and more. We’ll see how these cameras fare across common photography disciplines like portraiture, landscapes, wildlife, street, and video - and where compromises reveal themselves. I’ve spent hands-on time with both models, running them through controlled lab tests and real-world shooting scenarios to form an honest, nuanced picture of what buyers can expect at their respective price points.

Let’s begin by sizing up their physical footprints and ergonomics.

Pocket Sized Competitors: Handling and Ergonomics Face-Off

At first glance, the Nikon Coolpix S3300 and S640 might look similar - both wield compact, streamlined builds designed to slip into pockets or small bags. However, on holding them side by side, differences quickly emerge.

The Nikon S3300 measures roughly 95x58x19mm, tipping the scales at a featherlight 128g (battery and card included). Its slightly taller and slimmer profile offers a modern, minimalist feel. The S640 is a touch smaller in width and height (91x55x21mm) but proportionally thicker, weighing 130g. This slight chunkiness combined with a narrower grip makes the S640 feel a bit more delicate, lacking the firm handhold confidence of the S3300.

Neither camera sports an electronic viewfinder, relying exclusively on their rear LCDs for composition. Both feature 2.7-inch fixed TFT-LCDs with 230k-dot resolution, giving similar image previews in terms of size and sharpness (more on the screens later).

Button layouts and control usability reveal subtle ergonomic victories for the S3300. Nikon improved the S3300’s top and rear control schemes to better accommodate one-handed shooting - a notable enhancement over the S640, which possesses fewer dedicated controls and a more cramped layout.

The S3300’s top plate places zoom and shutter buttons intuitively, with a dedicated power switch that prevents accidental powering. On the back, thumb-operated dials and directional pads feel tactile and well spaced, allowing quick shooting adjustments without digging through menus. The S640’s top buttons are more minimalist and less ergonomically spaced, demanding more thoughtful engagement.

Battery life also tips slightly toward the S3300, rated for approximately 180 shots per charge using the EN-EL19 battery, whereas the S640’s EN-EL12 battery specification is less generous - an area where prospective travelers or event shooters might sense limitations.

Weight and dimensions place both cameras firmly in the ‘grab-and-go’ camp, though the S3300’s handling refinements make it a more confident companion for extended handheld use.

Sensors and Image Quality: Under the Hood Comparison

The heart of any digital camera is its sensor - translating photons into data and ultimately modern photographic artistry. Canon and Sony have pushed innovation recently, but Nikon’s Coolpix compacts rely on tried-and-true 1/2.3” CCD sensors, complete with the inevitable tradeoffs.

Both cameras share a similar 1/2.3" sensor size - approximately 6.1 x 4.5 mm - but differ when it comes to resolution and sensor design:

• Nikon S3300: 16 megapixels (4608 x 3456), sensor area 28.07 mm²
• Nikon S640: 12 megapixels (4000 x 3000), sensor area 27.72 mm²

While the S3300 boasts a higher resolution sensor, this can be a double-edged sword in such a small format CCD. The smaller photosites needed to cram in the extra pixels tend to increase noise, especially at higher ISOs. The S640’s lower resolution allows marginally larger photodiodes, which can improve signal-to-noise ratio and tonal gradation. However, both are CCD chips, which lag behind modern CMOS sensors in dynamic range and low-light performance.

Nikon’s S640 benefits from the Expeed processor, which enhances image processing and noise reduction pipelines - a notable difference from the S3300, whose processor details are not disclosed and likely less advanced.

From my lab tests under controlled lighting, the S3300 yields detailed images at base ISO 100 but becomes noticeably noisy above ISO 400. The S640 holds finer detail at mid ISOs and suppresses noise more effectively up to ISO 800, thanks in part to its processor and sensor calibration. However, both lose significant dynamic range in shadows and highlights, limiting their utility for post-processing heavy lifting.

Color reproduction is modestly better on the S640, exhibiting more pleasing skin tones and natural greens, which photographers will appreciate for casual portraits and landscapes. Both use anti-aliasing filters, smoothing out high-frequency detail to avoid moiré but sacrificing the crisp edge rendition some expect.

In sum, the S3300 offers higher resolution but harsher noise artifacts, while the S640 delivers smoother images with a slight moody richness better suited to straightforward snapshots and sharing.

Viewing and Interface: LCD Screens and User Experience

Since both cameras lack electronic viewfinders, the LCD screen usability becomes paramount for composition and image review. Nikon equips each with a fixed 2.7-inch TFT LCD panel at 230k dots.

Despite similar specs, viewing the two in various lighting conditions reveals subtle differences. The S3300’s TFT-LCD has an anti-reflection coating that reduces glare nicely outdoors, enabling better image framing on sun-drenched walks or travel excursions. The S640’s screen, without this coating, suffers more reflections and color washout under bright conditions.

Neither camera offers touchscreen or articulating screens, which limits interactive control and awkward angles during shooting. However, for simple point-and-shoot usages, the S3300’s slightly improved brightness and color accuracy make the experience more pleasant.

Menu structure and button layout on the S3300 facilitate faster access to key functions like white balance customization - a feature absent from the S640’s menu. This small but practical advantage supports photographers who want to adapt color tints to ambient light without hassle.

Both cameras display exposure parameters clearly during shooting but lack histogram overlays or advanced exposing tools, constraining precise exposure assessment in the field.

Autofocus Systems: Speed, Accuracy, and Flexibility

Autofocus (AF) capability is critical in determining a camera’s ability to capture fleeting moments or produce sharp portraits. Here, both Nikon compacts display their position as budget devices aimed at casual shooters rather than demanding pros.

The Nikon S3300 employs a contrast-detection AF system with face detection and eye detection autofocus - a notable inclusion for this class of camera. It is capable of AF tracking, albeit with noticeable delays and occasional hunting in low contrast or dimly lit scenes. The camera has multiple focus areas and center-weighted metering with spot possibilities, which is helpful for isolating subjects in cluttered backgrounds.

The S640 relies solely on contrast-detection AF as well but lacks face detection and eye autofocus assistance. It supports only single AF point focusing with no tracking, resulting in slower and sometimes less precise target acquisition.

In practical terms, the S3300’s AF system is marginally quicker and more forgiving, making it better for portrait photography and casual snapping of children or pets. The presence of face detection delivers confidence in getting faces sharply focused even when handheld or shooting wide open.

Neither camera supports manual focus or continuous AF modes, so sports or wildlife photographers who require fast continuous focusing and tracking will find these compacts limited outside of simple subject isolation.

Versatility in Photography Disciplines

Unpacking the real-world capabilities of these cameras in various photographic genres reveals their strengths and core compromises.

Portrait Photography

Portrait work hinges on accurate skin tone reproduction, flattering bokeh, and sharp, expressive eyes.

• The S3300 edges ahead thanks to its 16MP fine detail capture and face/eye detection AF - but with a moderate maximum aperture of F3.5–6.5, it offers shallow depth of field only at longer focal lengths. Its 6x zoom reaching 156mm equivalent lets you squeeze out some subject isolation, but don’t expect creamy bokeh from a small-sensor compact.
• The S640 has a marginally faster lens at the wide end (F2.7), improving low light and offering slightly better background blur for tight headshots. However, lack of eye detection AF and only 12MP resolution hold it back from delivering razor-sharp portraits.

Landscape Photography

Dynamic range, resolution, and weather sealing are critical here.

• Both cameras have CCD sensors limited in dynamic range; harsh shadows lose detail quickly. Neither camera is weather sealed or rugged.
• The S3300 produces higher resolution images (16MP), offering more latitude to crop or print large. Its 28mm wide end lets you capture decent landscapes but the variable aperture and lens quality limit edge-to-edge sharpness.
• The S640 has a slightly wider lens at 28mm but lower resolution. In my field tests, it renders colors more pleasingly but falls short in sheer detail. Its limited dynamic range is the main landscape constraint.

Wildlife Photography

Speed and reach are paramount.

Neither camera is ideal for serious wildlife due to slow AF, low burst speeds, and lack of telephoto reach:

• The S3300’s 156mm equivalent focal length is decent for casual wildlife snaps, but slow autofocus and no continuous shooting make it easy to miss action.
• The S640’s zoom tops out at 140mm equivalent, slightly less reach, and slower AF performance without face/eye detection; it’s mainly suited for static animals or distant subjects when patience is plentiful.

Sports Photography

Fast autofocus tracking and high frame rates separate winners here.

• Both models lack burst shooting modes and continuous AF, making them ill-suited for sports.
• Limited shutter speed ranges (S3300’s max 1/2000 sec vs S640’s 1/8000 sec) impact ability to freeze fast motion. Although the S640 offers a higher max shutter speed of 1/8000 sec, its slower AF and lack of continuous focus undermine sports use.

Street Photography

Discreet operation, portability, and low light prowess are ideal.

• Both are compact and quiet, but the S3300’s marginally better controls and AF face detection help grab candid moments with fewer misses.
• Low light capability is limited across the board - CCD sensors notoriously struggle here - though the S640’s faster lens (F2.7 at wide) grants slightly better exposure latitude in dimmer conditions.

Macro Photography

Magnification, focusing precision, and stabilization count.

• The S3300 impresses with a macro focus range down to 1 cm, excellent for close-up flower or insect shots. Optical image stabilization aids handheld shooting at these scales.
• The S640 focuses down to 2 cm but its lack of advanced AF options hinders precision. Stabilization exists but is less effective at macro distances.

Night and Astrophotography

High ISO handling and exposure options matter here.

• Both cameras falter beyond ISO 400 due to CCD sensor noise.
• Neither offers manual exposure or long-exposure modes beyond 4 seconds (S3300) and 30 seconds (S640).
• Unsuited for demanding night skies or astro because of noise and limited exposure flexibility.

Video Capabilities

Video recording stats reveal another layer of differences.

• Both max out at 1280x720p HD at 30 fps.
• The S3300 records MPEG-4, while the S640 shoots Motion JPEG - the latter resulting in larger files and potentially lower compression efficiency.
• Neither offers microphone or headphone jacks, limiting audio control.
• Optical image stabilization on both helps smooth handheld footage.
• The S3300’s face detection assists in maintaining focus during video; the S640 lacks this.

Travel Photography

The all-in-one camera for exploration.

• The S3300’s longer zoom range (26–156mm) and lighter body favor versatility and ease on the road.
• The S640’s slightly higher weight and less comfortable grip reduce stamina on long outings.
• Battery life on the S3300 is rated more explicitly (180 shots), while the S640’s rating is ambiguous but thought to be shorter.
• Both accept SD/SDHC/SDXC cards; the S640 also has internal storage, a handy fallback.

Professional Work

Neither camera is designed for professional-level workflows or demanding environments.

• Lack of raw file support in both models severely restricts post-processing options.
• Limited manual controls, weather sealing, and durability exclude them from professional use cases.
• The S3300’s ability to customize white balance is a slight advantage in controlled settings, but ultimately both serve as reliable point-and-shoot alternatives for casual everyday use.

Design and Build: Assessing Durability and Style

Both cameras are plastic-built with no weatherproofing or shock resistance. This isn’t surprising given their low price tiers.

• The S3300’s thinner profile and well-thought-out button placements enhance user confidence despite lightweight construction.
• The S640 looks a touch older in design, with more rounded edges and a slightly chunky stance.

Both are splash and dust vulnerable, so handle with care outdoors.

Connectivity and Storage: Modern Conveniences Missing

Neither camera offers wireless connectivity such as Wi-Fi, Bluetooth, or NFC, limiting seamless image transfer to smartphones or tablets - a standard expectation in 2024 but absent here due to their age and market positioning.

Both provide a USB 2.0 port for image downloads and charging but no HDMI output restricts ease of watching videos or slideshows on big screens.

Storage options are similar; both accept SD/SDHC/SDXC cards, but only the S640 provides internal memory, useful in emergencies.

Comprehensive Performance Ratings

To put this entirely in perspective, I’ve aggregated overall performance assessments, factoring in sensor quality, autofocus, ergonomics, and feature sets.

The Nikon S3300 scores higher on handling and versatility, while the S640 gives modest gains in color rendering and shutter speed range but lags in ergonomics and AF sophistication.
