Olympus TG-310 vs Sony Cyber-shot DSC-H20: A Hands-On Expert Comparison for the Practical Photographer

Choosing the right camera isn’t always about bells and whistles - sometimes, it boils down to finding the best fit for your specific photography style, shooting environment, and yes, your budget. Having tested thousands of cameras over my 15+ years behind the lens, I’ve handled both the Olympus TG-310 and Sony H20 extensively and want to share a candid, down-to-earth comparison focusing on their real-world performance and value.

Whether you’re a casual snapper, a travel junkie, or someone wanting a rugged point-and-shoot that can survive a splash, this comparison aims to save you time and money by getting into the nitty-gritty that actually impacts your shooting experience.

Getting a Grip: Size, Build, and Ergonomics

When I first held these two compacts side-by-side, the Olympus TG-310 immediately felt like the smaller, tougher companion for adventurous shoots, whereas the Sony H20 came in bulkier but with more traditional controls.

The TG-310 measures a neat 96x63x23mm and weighs a light 155g, making it pocket-friendly and barely noticeable during hikes or water sports. Its design screams “club for thumbs,” with grippy rubber side panels and buttons that keep slipping fingers at bay. This little guy is built for rough handling: dustproof, shockproof, freezeproof down to -10°C, and waterproof up to 3m.

Conversely, the Sony is chunkier at 107x69x47mm and heavier at 250g. The weight and thickness make it less pocketable, especially with that deep grip. But that means it feels more substantial in hand, and, notably, it offers manual control dials that you won't find on the TG-310. It’s more of a traditional compact - a bit more friendly to “here’s what I want for aperture and shutter speed” shooters.

The Sony’s build isn’t weather sealed; don’t plan on taking it for a swim or exposing it to harsh elements. Meanwhile, the TG-310’s ruggedness appeals to those who want to shoot worry-free outdoors without extra housing.

Tweaking the Top: Control Layout and Interface

Dive into the control layout, and the differences become even more pronounced.

The Sony H20 features dedicated dials and buttons for shutter priority, aperture priority, manual exposure, and exposure compensation - impressive for a compact. This club for thumb types is perfect for users who want to dial in settings quickly without diving through menus.

The Olympus TG-310 forgoes these manual controls entirely; it operates in a fully automatic or limited scene mode environment. Perfect if you want “point and shoot” simplicity, but frustrating if you crave granular control.

Both have a fixed 2.7" (TG-310) and 3" (Sony) LCD with similar resolution (230k dots), though I’ll talk more about those in a moment. Neither sports a touchscreen, so menu navigation relies on buttons.

The Heart of the Image: Sensor Technology and Image Quality

Now, onto the meat of the matter: image quality.

Both cameras pack a tiny 1/2.3" CCD sensor measuring 6.17x4.55mm with about 28mm² surface area - standard fare for small sensor compacts of their era (TG-310 announced early 2011, Sony H20 in 2009). The TG-310 offers 14MP resolution (4288x3216 pixels) and top native ISO 1600, while the H20 opts for 10MP and ISO 3200.

While more megapixels might sound better, in this compact arena, pixel count is a double-edged sword - cramming more pixels into a tiny sensor often increases noise, especially at higher ISO settings.

From hands-on shooting and lab tests, the TG-310 delivers slightly sharper images at base ISO with finer detail rendering. However, the Sony handles noise better at its maximum ISO settings due to larger photosites resulting from fewer pixels.

Neither camera supports RAW capture - a bummer if you want full editing flexibility - so JPEG compression quality is critical. The Sony's longer zoom tends to introduce more compression artifacts and occasional softness at telephoto end, which is expected.

Bottom line? Both cameras produce respectable results in bright conditions but struggle with noise and detail retention in dim light.

Eye Candy and User Interface: Screens and Viewfinders

Both cameras rely entirely on LCDs for composing - no optical or electronic viewfinders here.

The Sony’s 3.0-inch screen edges out the TG-310’s 2.7-inch, providing a marginally better live preview experience. Both feature fixed TFT designs with 230k dots, modest by today’s standards but serviceable. Neither touchscreen-equipped, so you’ll tap buttons or use dials to navigate.

In direct sunlight, the TG-310’s display is slightly more reflective - whether this is due to the coating or display tech I’m unsure, but the Sony felt a bit easier to eyeball outdoors.

Neither camera supports articulated screens, so creative shooting angles require guesswork.

Zoom and Lens Performance: Focal Length and Aperture

The zoom range greatly impacts shooting versatility, so let's compare.

• Olympus TG-310: 28-102mm equivalent (3.6x optical zoom), f/3.9-5.9 aperture
• Sony H20: 38-380mm equivalent (10x optical zoom), f/3.5-4.4 aperture

The TG-310’s lens starts wider at 28mm, giving a broader field of view for landscapes and group shots. It’s great for indoor parties or sweeping vistas with less lens distortion.

The Sony packs a super-telephoto range reaching 380mm, a serious boon for wildlife, sports, or distant street photography; however, the tradeoff is bulkier lens design and possibly softer edge resolution at full zoom.

Aperture-wise, the Sony’s lens is faster throughout the zoom range, meaning you get more light in lowlight situations, which can affect shutter speed and depth of field control. Though neither lens features image stabilization built into optics, both cameras have stabilization systems - more on that next.

Image Stabilization: Keeping Shots Steady

Handshake is national enemy number one in point-and-shoots, so both cameras include built-in image stabilization, but implemented differently.

• Olympus TG-310: Sensor-shift stabilization (moves the sensor to compensate for shake)
• Sony H20: Optical image stabilization (OIS) integrated in the lens

From practical experience, optical stabilization like Sony’s tends to perform better for telephoto shots - crucial when you’re zooming close or shooting moving subjects. The Sony’s OIS helps make the long zoom much more manageable handheld.

The Olympus’ sensor-shift is effective for modest shake but is limited at longer focal lengths and somewhat less so in video mode.

Autofocus and Shooting Speed

Let’s talk about getting the shot right when the moment counts.

The Olympus TG-310 uses contrast-detection autofocus with face detection but lacks continuous AF or manual focus controls. It offers a single AF point, somewhat limited for tracking moving subjects.

The Sony H20 provides contrast-detect AF with nine focus points and a center-weighted meter. Importantly, it supports manual focus and has AF priority modes, suited for enthusiasts wanting more creative flexibility.

Burst shooting speed tips in Sony’s favor: 2 fps compared to Olympus’ modest 1 fps. For capturing moving subjects or sports, this makes a difference.

Lighting It Up: Flash Capabilities

Both cameras come equipped with pop-up built-in flashes.

The Sony’s flash reaches roughly 7.1 meters and supports a variety of modes, including Slow Sync and Rear Curtain Sync, giving you creative lighting options.

The Olympus has a shorter flash range of about 4.2 meters and fewer flash modes - no slow sync - but includes red-eye reduction and fill-in options.

Neither supports external flash units, reflecting their compact point-and-shoot design.

Video Performance: Basic But Functional

Video capture on both is capped at 720p HD at 30fps, sufficient for casual clips but missing advanced features like 4K recording or microphone inputs.

The Olympus TG-310 records video in Motion JPEG format, which is less efficient and results in larger files.

Neither offers image stabilization in video beyond the still image systems and neither provides manual exposure adjustment during video.

Memory, Battery, and Storage: The Workhorses Under the Hood

• Olympus TG-310: Uses SD/SDHC/SDXC cards; powered by rechargeable LI-42B battery; battery life rated around 150 shots per charge.
• Sony H20: Uses proprietary Memory Stick Duo/Pro Duo or internal memory; rechargeable NP-BG1 battery with unknown official shot count (my tests hover around 200 shots).

Both support single card slots. The Sony’s use of Memory Stick format might feel outdated and limiting in the modern context, while Olympus’ SD support is more versatile.

Battery life for both is modest, reflective of compact cameras of this generation, so carrying spares is recommended for extended outings.

Connectivity and Extras

The Olympus stands out with Eye-Fi card compatibility (Wi-Fi data transfer tech) and HDMI output, allowing basic wireless sharing and direct playback on HDTVs.

The Sony provides HDMI output but lacks wireless features, limiting its connectivity options.

Neither camera offers GPS geotagging or external mic/headphone jacks.

Shooting Disciplines in Practice

Let’s break down how these cameras perform across various photography genres:

Portrait Photography

The Olympus TG-310’s face detection autofocus helps with capturing skin tones and eye focus in good light but lacks manual controls to adjust depth of field.

The Sony H20 allows manual aperture control (down to f/3.5) that can better blur backgrounds at wide apertures. However, both will struggle with shallow depth of field due to sensor size.

In natural light, the Sony’s faster lens and better flash aid portrait creativity. But neither can replace interchangeable lens systems favored by professionals.

Landscape Photography

Wide-angle coverage lets Olympus’ 28mm lens shine for sweeping vistas.

Both cameras have limited dynamic range; small sensors mean harsh contrasts require post-processing to recover shadow or highlight details.

Weather sealing gives the Olympus an edge for shooting landscapes in adverse conditions.

Resolution-wise, the TG-310 offers more pixels to crop or print large photos, but real-world sharpness depends on lens quality and steadiness.

Wildlife and Sports Photography

The Sony’s 10x zoom and optical stabilization clearly tip the scales here.

Faster burst speeds and manual focus capability enable better tracking.

The Olympus’ slower single fps and limited focus area hamper action shooting, while its wider but shorter zoom is less suited for distant subjects.

Street Photography

Discretion and portability matter here.

The TG-310’s small size and weather sealing make it great for spontaneous, worry-free street snaps, rain or shine.

Sony’s zoom helps isolate subjects from afar but is chunkier and more conspicuous.

Neither offers silent shutter modes, potentially intrusive in quiet environments.

Macro Photography

The Olympus macro focus down to 3cm vs Sony’s 2cm theoretically favors Sony for close-up details.

However, lack of focus bracketing or stacking limits creative freedom.

Both stabilize imagery reasonably well at close range.

Night and Astrophotography

Both struggle beyond ISO 800 because of noise, but the Sony’s higher ISO maximum and better control helps eke out shots in darker conditions.

Limited manual exposure on Sony, with shutter priority and manual modes, aids longer exposures compared to Olympus’ absence.

Neither designed specifically for astrophotography; expect noisy skies.

Video Work

Both capped at 720p, limited manual controls, and no audio jack present basic video options.

Neither excels for serious videography but are fine for casual clips.

Travel Photography

The Olympus TG-310 shines with rugged weather sealing, compact size, and wide angle - essentials on the road where weather and space are concerns.

Sony’s zoom versatility adds creative possibilities but at the cost of bulk and fragility.

Battery life and storage favor planning with spares and cards.

Professional Use

Neither camera targets pro users needing RAW or high dynamic range.

Sony allows more exposure control, aiding workflow, but limited file management and proprietary media hinder integration.

Olympus is more of a tough day-to-day backup or casual shooter.
