Nikon Coolpix S640 vs Sony Cyber-shot HX50V: An Expert’s Take on Two Compact Captures

When it comes to compact cameras, the balance between portability, zoom range, image quality, and user experience can be tricky. Today, I’m diving into a detailed comparison between two cameras that cater to enthusiasts looking for easy handling with decent zoom chops: the Nikon Coolpix S640 (introduced in 2009) and the Sony Cyber-shot DSC-HX50V (launched in 2013). While both fall within the compact class, they represent different eras and philosophies in small sensor compacts - and that makes for an interesting head-to-head.

Having tested thousands of cameras over the years, I’m going to walk you through every aspect that matters - from sensor and lens to ergonomics, shooting versatility, and image quality. Let’s unpack the strengths and limitations of each, grounded in real-world use and backed by technical insights.

Size, Shape, and Handling: How Do They Feel in Your Hands?

Starting with physical form, the S640 and HX50V target quite different priorities, and you can feel it immediately holding them.

Nikon’s S640 is a true compact: slender, lightweight (around 130g), with minimal bulk - measuring just 91x55x21 mm. It effortlessly slips into pockets or smaller bags, making it a straightforward grab-and-go for casual shooting or travel where size matters most.

In contrast, Sony’s HX50V is noticeably bigger and heavier at 272g, measuring 108x64x38 mm, a consequence of packing in a much longer 30x zoom (more on that shortly). The grip feels more substantial, and controls are more prominent - helping with stability, but at the cost of pocketability.

This difference in ergonomics is well illustrated in the top-down design comparison:

The HX50V sports a more detailed and tactile control layout, including dedicated dials for exposure compensation and access to manual modes - a boon for users wanting creative control. The Nikon S640 foregoes these, focusing on simplicity with fewer buttons and a basic mode dial, targeting users who prefer point-and-shoot convenience.

If portability and pocket-friendliness top your list, the S640 wins here hands down. But if you want a better grip and more manual handling options, the HX50V doesn’t disappoint.

Sensor and Image Quality: How Much Resolution and Performance Matter?

Now let’s dig under the hood where image quality is born - the sensor.

Both cameras use small 1/2.3” sensors, but the Nikon S640 opts for a 12-megapixel CCD sensor, while the Sony packs a 20-megapixel backside-illuminated (BSI) CMOS sensor. That’s a significant generation gap and technological swing.

Why does that matter? First, the Sony’s BSI-CMOS sensor provides better light gathering efficiency, leading to improved low-light performance and dynamic range compared to the older CCD tech in the Nikon. Additionally, Sony’s nearly double pixel count lets you capture more detail, making it advantageous if you want large prints or cropping flexibility.

The slight difference in sensor dimensions (Nikon’s 6.08x4.56 mm vs Sony’s 6.17x4.55 mm) is negligible, so it’s the sensor type and pixel count that play a defining role.

In campaigns pushing the limits of both cameras, I noticed the S640 produces reasonably sharp images in daylight but struggles in low light, yielding more noise and softer detail. The HX50V handles ISO noise gracefully up to ISO 800, which opens doors to versatile shooting conditions.

Neither camera offers RAW support, limiting post-processing flexibility - a disappointment for professionals but somewhat expected in this compact class.

Bottom line: Sony HX50V delivers superior image quality overall, thanks to its advanced sensor and higher resolution. Nikon S640 can suffice for casual outings in bright conditions but will be less forgiving when light dims.

LCD and User Interface: Is the Viewfinder Missing a Punch?

Having an effective framing and review system is often overlooked in compacts, but it can either enrich or hamper your shooting experience.

The Nikon S640 sports a modest 2.7” LCD with a resolution of just 230k dots - a basic screen that’s sufficient outdoors only in good light, where reflections don’t interfere much.

Sony improves on this with a 3” fixed XtraFine LCD boasting 921k dots, offering crisp and bright image previews, better color accuracy, and more detailed menus that aids in framing and adjusting settings quickly.

Oddly, even though the Sony HX50V offers an optional electronic viewfinder (sold separately), neither model includes a built-in EVF - something I miss when shooting under bright sun or fast action where eye-level composition helps.

For those who prioritize quick and easy review or tripod shooting with live preview, the HX50V’s superior screen makes a real difference.

Lens and Zoom: Who Brings The Reach?

If you like exploring varied focal lengths without changing lenses, zoom specs are crucial, and here the two diverge worlds apart.

• Nikon S640: 28-140mm equivalent (5x zoom), aperture range F2.7-6.6
• Sony HX50V: 24-720mm equivalent (30x zoom), aperture range F3.5-6.3

Sony’s HX50V offers a massive focal range from moderate wide-angle through super-telephoto territory - a flexibility rarely seen in compacts.

This vast zoom range makes the HX50V a natural choice for wildlife, sports, and travel photography where you can’t always get close enough. However, such an ambitious zoom comes with tradeoffs: variable aperture dims quickly at the tele-end (F6.3), and image stabilization becomes mandatory to combat shake, especially handheld.

Nikon’s S640 has a shorter zoom but a slightly brighter maximum aperture at the wide end (F2.7) - better for indoor and low-light shooting at moderate focal lengths.

Both cameras feature optical image stabilization. In practice, the HX50V’s stabilizer maintains handheld sharpness surprisingly well at full zoom through highly effective lens-shift technology - a must-have with 720mm reach.

So if you crave extreme zoom versatility, Sony is the clear winner. For casual shooting and relatively bright environments, Nikon’s lens performs well and is easier to carry.

Autofocus and Shooting Speed - Fast Enough for the Moment?

For capturing fleeting moments, autofocus (AF) performance and burst rate matter.

The Nikon S640 uses a contrast-detection AF system with single-area focus, no face detection, and no continuous AF. This results in slower focus acquisition and a limited ability to track moving subjects.

Sony HX50V upgrades with contrast-detection AF featuring face detection and AF tracking, covering multiple focus areas. It can lock focus quickly in good light and continuously track moving subjects, which helps for street photography, casual wildlife, or sports.

Burst shooting capabilities further enhance fast action adaptability:

• Nikon S640: No continuous shooting mode (essentially single shot per trigger press)
• Sony HX50V: Up to 10 frames per second, quite impressive for a compact

In my field testing, tracking moving subjects was trying on the Nikon but relatively smooth on the Sony provided there’s adequate lighting.

Video Capabilities: Is It Casual or Semi-Pro Ready?

Video recording has become a standard camera feature, even in compacts.

• Nikon S640 offers HD video at 720p at 30fps using Motion JPEG codec - a simple but bulky and less efficient format, resulting in larger files. No manual video exposure control.
• Sony HX50V supports Full HD 1080p recording at 60fps, with more compressed MPEG-4 or AVCHD codecs, resulting in better quality files. It also offers manual exposure modes during video, enhancing creative freedom.

Neither camera supports microphone or headphone ports, so audio is fixed and basic, but Sony’s video output benefits from smoother frame rates and higher resolution. Also worth noting, Sony includes HDMI output for easier playback on TVs.

For enthusiasts wanting better video quality from a compact, Sony is head and shoulders ahead.

Durability and Build: How Tough Are They?

Neither camera boasts weather sealing or ruggedness features such as dustproof, shockproof, or waterproof ratings - typical for compacts from their periods.

Nikon’s S640 is lightweight but feels plasticky, while Sony’s HX50V has a more solid, albeit heavier body that inspired me to trust it in more varied shooting conditions.

Neither is freeze or crushproof, so treat both as delicate gadgets rather than outdoors tough companions.

Battery Life and Storage: How Long and How Much?

Sony HX50V has the better battery endurance with an official CIPA rating around 400 shots per charge using the NP-BX1 battery pack - a respectable figure for a zoom camera capable of long zoom bursts.

Nikon S640 specs don’t specify exact battery life, but typical usage tests indicate lower endurance given smaller form factor and older battery tech (EN-EL12). For extended outings, you’ll likely want a spare.

Storage-wise, both rely on SD/SDHC cards, but Sony also includes compatibility with Memory Stick Duo formats, giving some flexibility for users with legacy media.

Connectivity and Extra Features: Staying Modern?

For connectivity, the Sony HX50V offers built-in Wi-Fi (surprisingly missing Bluetooth and NFC though), and GPS logging - a neat bonus for traveling photographers wanting automatic geotagging.

Nikon’s S640 lacks wireless features entirely, reflecting earlier design timelines.

Sony also includes HDMI output and manual exposure controls plus white balance bracketing - attractive for serious enthusiasts, while Nikon keeps it simple.

Performance Summary and Scores: Where Does Each Camera Shine?

After months of side-by-side shooting and analysis, here’s an overview of their core performance metrics:

Sony’s HX50V scores clearly higher across image quality, autofocus, video, and zoom versatility. Nikon’s S640 finds favor for pocketability and simplicity but falls short in most other areas.

Here’s how the cameras perform across popular photography types:
