Nikon S31 vs Nikon S620

Nikon Coolpix S31 vs. Nikon Coolpix S620: A Hands-On Comparison for Every Photographer

Over my 15+ years as a camera reviewer and photographer, I’ve tested everything from pro-level DSLRs to compact point-and-shoots. Today, I’m diving into two older but still intriguing Nikon compacts - the ruggedly simple Coolpix S31 and the versatile Coolpix S620. Though they don’t compete in the current mirrorless-heavy market, both cameras serve distinct needs and niches. I’ve put them head-to-head across a variety of photography scenarios to gauge their real-world strengths, weaknesses, and value propositions.

What follows is a detailed look at how these cameras perform in portrait, landscape, wildlife, and other disciplines - not just spec sheets. I also share practical insights born from years of hands-on experience, so you can pick the right tool for your creative goals and budget.

First Impressions: Size, Build, and Ergonomics

Right out of the box, these cams feel different. The Nikon S31 stands out with its robust waterproof, shockproof, and freezeproof body designed for active, outdoor use. I took it kayaking and hiking - its sealed chassis gave me peace of mind in splashy or dusty conditions. The S620, meanwhile, is noticeably smaller and lighter but doesn’t have any environmental sealing.

Comparing their size and grip, the S31 is chunkier and thicker, tailored for durability, whereas the S620's slender profile boasts more traditional pocketability.

Handling-wise, the S31’s controls are large and simple, perfect for quick operation - even with gloves. The S620 packs into a slim shell with tiny buttons that take a bit longer to get used to, but it’s still comfortable for everyday street photography.

On top, both models provide straightforward control layouts but with some key differences:

The S620 offers a few more shooting modes and an adjustable self-timer, absent on the S31, which focused on durability over complexity. The S31 forgoes any manual or semi-manual modes, unlike the S620’s limited exposure flexibility through custom white balance.

Sensor and Image Quality: Basic CCD Tech, But Different Flavors

Both cameras rely on CCD sensors - a technology that’s fallen out of favor to CMOS but was common in compact cameras of their era. The S31 uses a 1/2.9” 10 MP sensor, while the S620 steps up slightly to a 1/2.3” 12 MP sensor with a larger surface area.

From a technical standpoint, the S620’s sensor size and pixel count offer a theoretical edge in detail and low-light performance. My test images confirmed this advantage: the S620 delivers clearer images with more natural colors under indoor and dim conditions. On the other hand, the S31 tends toward slightly noisier and softer images, though its JPEG processing is tuned for punchier colors - likely to appeal to casual users shooting in bright daylight.

With maximum native ISO capped at 6400 on the S620 versus 1600 on the S31, the former shows better versatility in low light, despite some grain at high ISO settings.

Viewing and User Interface: Similar But One Stands Out

Both cameras sport 2.7-inch LCDs with 230k-dot resolution, adequate but today fairly low-resolution. These fixed screens do the job for framing and playback, but neither offers a touchscreen or EVF.

I appreciate that the S620’s interface feels cleaner, with decent menus and a quick white balance adjustment. The S31’s UI is pared back to avoid confusion, suitable for its intended kid-friendly and outdoor audience. Neither supports touchscreen control, limiting their responsiveness compared to modern compacts.

Autofocus and Shooting Speed: Modest Performance for Casual Shots

Neither camera shines in autofocus sophistication. Both use contrast-detection AF without face or eye detection. The S620 autofocuses reasonably quickly in good light but can hunt indoors or in shade, especially on moving subjects.

The S31’s autofocus is noticeably slower and less reliable due to its simplified system focused on straightforward point-and-shoot use.

Continuous shooting rates are also minimal: the S620 offers a paltry 1 frame per second burst, and the S31 has no burst mode at all. This rules out these cameras for capturing action or fast-moving wildlife effectively.

Lens and Zoom: Fixed but Purposeful

The S31 sports a 29-87mm (35mm equivalent) zoom with a 3x range, while the S620’s 28-112mm zoom covers a wider reach at 4x. While neither lens is remarkably fast, the S620 boasts a bright f/2.7 aperture at the wide end - helpful for lower-light shooting and achieving some subject isolation.

Despite the S31’s rugged design, its modest zoom range limits flexibility. The S620’s longer zoom and close macro focusing down to 2 cm opened up more creative possibilities during my tests, from tight portraits to detailed flower shots.

Portrait Photography: Skin Tones and Bokeh in Practice

In controlled portrait tests, I found the S620’s slightly larger sensor and wider aperture deliver better skin tone rendering - more natural, less plasticky than the S31’s output. The S31’s image processing tends to smooth skin textures aggressively, which might appeal to parents shooting kids but falls short for serious portrait work.

Neither camera offers face or eye detection autofocus, so sharp focus on eyes depends heavily on your technique. The S620 can achieve mild background separation at its widest aperture and telephoto end, which helps isolate subjects indoors or in low light. The S31 struggles here, with a deeper depth of field that renders backgrounds mostly in focus and less bokeh effect.

Landscape Photography: Resolution, Dynamic Range, and Durability

When it comes to landscapes, the S620’s higher resolution and broader zoom make it more suitable for scenic shots, especially in good lighting. I enjoyed capturing vibrant sunset colors and textures with its 12 MP sensor producing sharp, punchy images. Its multi-segment metering allows balanced exposures when dealing with challenging lighting.

That said, the S31’s physical durability and weather sealing trump the S620 in outdoor scenarios where inclement weather is a concern. Taking the S31 onto the beach or into wet hiking trails was worry-free. It also survived brief freezes during winter shoots, a rarity for compacts.

Neither camera boasts excellent dynamic range - a limitation of their CCD sensors and modest processing - but the S620’s slightly better sensor area handles highlights and shadows with more grace.

Wildlife and Sports: Autofocus and Burst Rates Limit Potential

For photographing fast-moving subjects, I personally found these cameras lacking. With no continuous AF modes, face detection, or decent burst rates, neither the S31 nor the S620 proved reliable for capturing unpredictable wildlife or sports action.

The S620’s longer zoom range affords some distance advantage for wildlife, but autofocus latency and single FPS shooting rate are bottlenecks that will frustrate serious enthusiasts.

Street and Travel Photography: Practical and Portable?

Travel photography demands a light, versatile, and unobtrusive camera. The S620 is the clear winner here due to its smaller size and stealthier profile - perfect for candid street shots or city exploration without drawing much attention.

Its modest weight and decent zoom make it a great “grab-and-go” companion. The S31, though shockproof and waterproof, is bulkier and looks more like a rugged specialist camera - less suited to blending into urban settings.

Battery life is similar (rated about 260 shots for the S31, unspecified but generally modest for the S620) and both use the same EN-EL12 battery model. Neither supports fast charging or USB power, so packing spare batteries is advisable for traveling.

Macro and Close-Up Potential

The S620’s ability to focus down to 2 cm provides satisfying macro shots with sharp detail of flowers, insects, or small objects. The optical image stabilization really helps here, minimizing blur due to camera shake.

The S31 lacks macro focusing and image stabilization, so close-up work is limited and often softer. For anyone wanting to explore the tiny-world genre casually, the S620 is the obvious choice.

Night and Astro Photography: Testing Low-Light and High ISO

Both cams are modest performers in low-light. The S620’s higher max ISO rating (6400) outpaces the S31’s 1600, but noise becomes burdensome above ISO 800 on both.

Long exposures (up to 4 seconds on the S31, 8 seconds on the S620) allow some night scene capture, but without manual modes, it’s challenging to experiment fully. Neither camera has RAW support or bulb mode, limiting post-processing flexibility.

Video Capabilities: Basic Recording Only

In terms of video, the S31 offers HD 720p recording at 30fps - a nice surprise in this price bracket - but without external microphone input or advanced formats. The S620 peaks out at 640x480 VGA resolution, a significant limitation even at release.

Neither has image stabilization well-suited for handheld video, but the S31’s fixed lens zoom and waterproof body do open some creative water-related shooting options.

Build Quality, Weather Sealing, and Reliability

Environmental sealing is where the S31 really shines, making it ideal for adventurous users needing toughness above all. It holds up beautifully under splashes, dust storms, and subfreezing temperatures.

The S620, while pocket-friendly and sleek, offers no weather resistance and requires more careful handling in challenging environments.

Connectivity, Storage, and Battery

Both cameras rely on basic USB 2.0 for data transfer and lack wireless features like Wi-Fi or Bluetooth, which modern photographers expect. This is typical for cameras from this era.

Storage is via SD/SDHC/SDXC cards on both, and the S620 also has minimal internal memory, a nice fallback if you forget your card.

Battery life is similar; however, I always advise carrying a spare EN-EL12 battery for extended trips, considering these cameras’ modest capacities.

Price and Value: What Do You Get for Your Money?

As of now, the Nikon S31 is priced around $90 and the S620 closer to $37 in used or clearance markets - both entry-level prices.

Given these numbers, value depends heavily on very specific user needs:

• The S31 offers rugged durability and simple handling at a moderate price, perfect for kids, outdoor activities, or swimmers needing waterproof gear.
• The S620 delivers better image quality, more zoom reach, and versatility at a budget price, suited for casual beginners seeking a compact camera for travel or street use.

Neither offers professional-level features, but each fulfills a clear niche excellently.
