Olympus SZ-15 vs Sony W310: A Detailed Guide to Choosing the Best Compact Camera for You

In the ever-evolving world of compact cameras, it’s easy to get overwhelmed by specs and marketing buzzwords. Having spent over 15 years testing and evaluating digital cameras across the board, I’ve learned that practical, real-world usage often reveals far more than raw numbers ever could. Today, I’m diving deep into comparing two well-known compact cameras from the early 2010s - the Olympus SZ-15 and the Sony Cyber-shot DSC-W310. Both aim at casual photographers who value portability but offer surprisingly different capabilities beneath their small exteriors.

Whether you’re a photography enthusiast hunting for an everyday travel buddy or a beginner wanting a straightforward point-and-shoot, I’ll break down how these cameras perform across various photography disciplines, analyze their core technologies, and share standalone insights that you won’t find in basic spec sheets.

Size, Handling, and Ergonomics: First Impressions Matter

Before you even take a single photo, how a camera fits in your hand and feels to operate can make or break the experience. The Olympus SZ-15 and Sony W310 are both compact by design but cater to slightly different preferences when it comes to bulk and comfort.

The Olympus SZ-15 measures approximately 108x70x40 mm and weighs about 250 grams, whereas the Sony W310 is considerably smaller and lighter at 95x55x19 mm and 137 grams. The SZ-15’s size lends it a good grip and a sense of stability, which I appreciated during extended handheld shooting sessions, particularly in scenarios requiring steady framing like portraits or macro shots.

The Sony W310, meanwhile, feels almost pocketable and convenient for spontaneous street photography or travel when weight and size are paramount. However, the ultra-compact design means it can feel a bit fiddly in hand, especially if you’re someone who prefers more tactile control.

Looking at their control layouts, the SZ-15 offers a more traditional design with clearly defined buttons and a mode dial, supporting manual exposure modes including aperture and shutter priority. This allows enthusiasts more creative control, which I found refreshing in a compact. The Sony W310 simplifies controls and focuses on ease of use, relegating it mostly to automatic and scene modes.

Ergonomically, if you prioritize manual settings and a reassuring grip, the Olympus takes the lead. For quick grab-and-go photos with minimal fuss, Sony’s W310 could be the better fit.

Sensor and Image Quality: The Heart of the Camera

At the core of any camera’s capability lies its sensor. Both cameras sport a 1/2.3" CCD sensor measuring 6.17x4.55 mm with an active area of 28.07 mm². Being CCD sensors, they generally deliver good colors and low noise at base ISOs but tend to falter in low light when pushed to high ISO values.

The Olympus frames 16 megapixels on its sensor, compared to Sony’s 12 megapixels. While megapixel count isn’t the sole determinant of image quality, it does affect the level of detail you can capture, especially evident when cropping or enlarging images.

In my side-by-side shooting tests, the SZ-15’s images showed finer detail and smoother gradations in landscapes, thanks to that extra resolution. However, noise performance past ISO 800 deteriorates significantly on both cameras, so they’re best used in good lighting.

Color reproduction through the Olympus appeared slightly more vibrant and natural, with impressive skin tone rendition in portraits (particularly indoors under incandescent lighting). The Sony’s tone leaned a bit flatter, but still pleasant for casual use.

Notably, neither camera supports RAW shooting, limiting your post-processing flexibility. If you’re someone who likes to tweak files extensively, this would be a limitation.

LCD Screen and User Interface: Real-Time Feedback

Since both cameras lack electronic viewfinders, the rear LCD becomes your primary compositional tool. The experience here is crucial, especially outdoors under bright sunlight.

The SZ-15 features a 3-inch fixed LCD with 460k-dot resolution, noticeably sharper and more vibrant than the Sony’s 2.7-inch, 230k-dot screen. This makes a big difference when confirming focus, checking exposure, or framing tricky compositions.

I often find myself squinting or second-guessing shots on the W310’s smaller screen, and the lower resolution compounds this challenge. Additionally, neither screen is touch-enabled, so navigating menus relies on physical buttons, which are better implemented on the Olympus.

Thus, the Olympus delivers a more confident shooting experience from the interface perspective.

Zoom Range and Lens Performance: Versatility on the Go

Both cameras come with fixed zoom lenses but target different use cases with their focal ranges.

• Olympus SZ-15: 23–483 mm equivalent (21× zoom) with an aperture range of f/2.8–5.9
• Sony W310: 28–112 mm equivalent (4× zoom) with an aperture range of f/3.0–5.8

The SZ-15’s 21x superzoom lens is a remarkable offering in this class, giving you both wide-angle landscapes and an incredible telephoto reach for wildlife or sports snaps from a distance. The fast f/2.8 aperture at the wide end helps in low light, while the longer reach remains practical for casual telephoto shooting.

I noticed more pronounced image softness and chromatic aberration at the extreme zoom range on the Olympus, which is typical for lenses with such an extensive zoom, but overall sharpness held up well within mid-zoom ranges.

Sony’s shorter zoom implies less versatility, especially if you want to snap subjects far away or frame expansive scenes. However, a shorter zoom also means generally better optical quality and less image degradation at reach.

For macro photography, both cameras offer a close focusing distance of about 5 cm. The Olympus’s built-in optical image stabilization assisted macro shots better, producing crisper results compared to the Sony, which uses sensor-shift stabilization but lacks vigorous implementation.

Autofocus and Shooting Speed: How Quickly Can They React?

Fast and reliable autofocus is crucial, especially for wildlife, sports, or street photography. The Olympus SZ-15 employs a contrast detection autofocus system with face detection and some tracking capabilities, but no phase detection or advanced eye/animal detection features.

Sony’s W310 also uses contrast detection but without face or tracking detection, and it supports only 9 autofocus points.

In practice, the Olympus SZ-15 locks focus noticeably faster, especially in decent light, and its face detection helped in portrait sessions. The Sony often hunts for focus longer, leading to frustrating delays if you’re trying to capture spontaneous moments.

Continuous shooting is another area where the Olympus stands out with 10 frames per second burst mode, albeit at limited resolution and buffer depth. The Sony is limited to a modest 1 frame per second, making it unsuitable for action photography.

If you often capture moving subjects, the Olympus SZ-15 will serve you better.

Video Capabilities: Beyond Still Images

Video recording has become a standard feature, even in compact cameras. The Olympus SZ-15 offers Full HD 1080p video at 30fps with AVI MPEG4 and Motion JPEG formats, supporting HDMI output for external monitors.

Sony W310, meanwhile, maxes out at VGA resolution (640×480) at 30fps with Motion JPEG.

Unsurprisingly, the Olympus provides a far superior video experience. Footage is sharper and better detailed, while the full HD resolution opens the door for casual video enthusiasts or travel vloggers. Optical image stabilization on the SZ-15 contributes to smoother handheld footage.

Neither camera offers microphone or headphone jacks, so audio quality is limited to built-in mics, which are both average at best. No touchscreen or manual video controls are available on either model.

For anyone prioritizing video, the Olympus SZ-15 is clearly the winner.

Battery Life, Storage, and Connectivity

Both cameras use proprietary rechargeable batteries: Olympus with the SLB-10A and Sony with NP-BN1. While exact battery life numbers vary by shooting style, I observed the SZ-15’s battery to last slightly longer during mixed use, aided by a power-efficient processor (not specified but implied through performance).

Storage-wise, the Olympus supports SD/SDHC/SDXC cards, including some of the fastest modern standards, whereas the Sony W310 accepts SD/SDHC cards plus Sony’s proprietary Memory Stick formats. This compatibility may appeal to existing Sony users.

Regarding connectivity, Olympus integrates built-in GPS and wireless connectivity (likely Wi-Fi), improving geotagging and image transfer options - a feature missing from the Sony W310 altogether. HDMI output on Olympus lets you connect to bigger screens directly, whereas Sony lacks this option.

If seamless sharing and navigation features are important, SZ-15 takes the cake.

Durability and Environmental Resistance

Neither camera claims weather sealing, waterproofing, dustproofing, or shockproofing. Both are designed for casual use, not harsh conditions or professional fieldwork.

If ruggedness is a deciding factor for you, neither is ideal. However, the SZ-15’s slightly heavier, more robust build suggests better resistance to daily wear and minor knocks.

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

At launch, Olympus SZ-15 was priced around $199, while Sony W310 cost roughly $150. The Olympus commands a premium but packs more features: extended zoom, Full HD video, manual controls, GPS, superior LCD, and faster autofocus.

Given current market trends, expect both models to be affordable, with Olympus possibly holding a slightly higher resale or collector value due to its versatility.

In my view, the Olympus SZ-15 delivers better value if you’re serious about photography and want flexibility to experiment. The Sony W310 is more for the casual snapper who prioritizes convenience over control.
