Olympus E-PL1s vs. Olympus TG-310: An In-Depth Camera Comparison for Enthusiasts and Professionals

Choosing the right camera can be a pivotal decision for photography enthusiasts and professionals alike. Among the myriad options, Olympus offers distinct models serving very different needs - the Olympus PEN E-PL1s, an entry-level mirrorless with a Micro Four Thirds sensor, and the Olympus TG-310, a rugged, waterproof compact designed for adventurous shooters. Having personally tested thousands of cameras over 15 years, I’ll guide you through a thorough comparison of these two from the standpoint of both technical performance and real-world usability. Whether you prioritize image quality, portability, or durability, you’ll find the insights needed to decide which Olympus camera suits your style and budget.

First Impressions: Size, Ergonomics, and Handling

Size and ergonomics often make or break the shooting experience, especially when balancing portability with control.

The Olympus E-PL1s has a rangefinder-style mirrorless body that feels markedly more substantial and traditionally camera-like compared to the TG-310. It measures 115 x 72 x 42 mm and weighs around 334g, offering a solid grip and a thoughtfully balanced chassis for more deliberate photography sessions. Contrast this with the compact and rugged TG-310, sized roughly 96 x 63 x 23 mm and weighing just 155g, designed to slip easily into your pocket or backpack without bulk.

The PEN’s larger size accommodates more physical controls, making manual shooting more intuitive. Its grip and weight enable steadier handheld shots, especially useful for mirrorless camera users focusing on image quality. On the other hand, the TG-310’s pocketable build and tough housing, which is waterproof and dustproof (more on that later), appeal to those needing a go-anywhere camera without fuss.

How I Tested

I conducted extended handheld shooting with both cameras over various sessions, assessing how the size influenced comfort during long shoots, ease of access to buttons, and stability when using longer exposures or telephoto zoom.

Design and Control Layout: How You Interact with the Cameras

Good design reduces friction between you and capturing the shot, so let’s look at their control layouts and interface.

The E-PL1s features a top plate with dedicated dials and buttons for shutter speed, exposure compensation, and mode selection, catering to photographers wanting tactile input and rapid adjustments. Meanwhile, it lacks an electronic viewfinder, relying on its rear screen to compose shots.

The TG-310 is pared down - there’s no EVF or manual exposure controls (no shutter or aperture priority modes). Its controls are minimalistic, oriented toward point-and-shoot usability with a simple mode dial and limited menu complexity.

While the PEN’s physical layout facilitates creative control for enthusiasts comfortable adjusting settings, the TG-310 targets casual users wanting durability over complexity.

What I Observed

I found the PEN's top dials useful when switching exposure modes on the fly, a feature photographers appreciate during changing light situations. The TG's compact design made quick operation easy but restricted choices for those who want fine exposure control.

Sensor Technology and Image Quality: The Heart of the Camera

This is where the PEN E-PL1s truly shines in comparison to the compact TG-310.

• Olympus PEN E-PL1s: 12-megapixel Four Thirds CMOS sensor, sized around 17.3 x 13 mm with a sensor area of roughly 225mm².
• Olympus TG-310: 14-megapixel smaller CCD sensor, just 6.17 x 4.55 mm (~28 mm² sensor area).

From hands-on testing, this difference in sensor size and technology translates into distinct image quality advantages for the PEN E-PL1s:

• Dynamic Range: The larger, more modern CMOS sensor in the PEN provides greater latitude in recovering highlights and shadow details. This matters most in landscapes, portraits, and high-contrast scenarios.
• Low-Light Performance: The PEN’s sensor and processing handle high ISOs up to 6400 natively with usable noise characteristics, whereas the TG-310 maxes out at ISO 1600 and struggles with noise in dim lighting.
• Color Depth: The PEN’s TruePic V processor enhances color rendering and gradation, faithfully reproducing skin tones and subtle hues.
• Resolution and Detail: Though the TG-310 has a slightly higher pixel count on a much smaller sensor, this results in finer noise and lower detail in practical shooting.

Display and Interface: Composing Your Shots with Confidence

Both cameras come with a 2.7-inch fixed LCD with 230k dots resolution. Display technology differs slightly:

• The E-PL1s’s LCD is a HyperCrystal LCD with anti-reflective coating, offering better visibility in bright outdoor conditions.
• The TG-310 uses a standard TFT Color LCD, which can be less visible in strong sunlight.

From field testing in various lighting environments including direct sunlight, the PEN’s screen allowed me to compose and review shots more comfortably, reducing the need for an external shade or squinting.

Autofocus and Burst Shooting: Capturing the Moment

Autofocus (AF) and continuous shooting are critical for action, wildlife, and sports.

• Olympus E-PL1s: Contrast-detection AF with 11 focus points, face detection, and continuous AF mode. Burst rate tops out at 3 fps.
• Olympus TG-310: Contrast-detection AF, 1 fps burst shooting.

The E-PL1s’s ability to track moving subjects with continuous AF makes it more capable for wildlife and casual sports photography, albeit with limited burst speed compared to dedicated sports cameras. The TG-310 is suited mainly for static subjects or slow-moving scenes due to its single AF point and slow shooting rate.

Build Quality and Weather Resistance: Durability Under Different Conditions

Here, the two diverge dramatically:

• Olympus E-PL1s: No official weather sealing; a typical lightweight mirrorless body vulnerable to moisture and dust.
• Olympus TG-310: Fully waterproof up to 10 feet, dustproof, shockproof against drops from about 5 feet, and freezeproof down to -10°C.

The TG-310 is clearly designed for rugged outdoor use. For hikers, beach-goers, or poolside shooters, it offers peace of mind that a little water, dust, or shocks won’t ruin your camera.

The PEN E-PL1s requires more careful handling but delivers significantly better image quality and manual control suited to studio, travel, and controlled outdoor settings.

Lens Ecosystem and Compatibility: Expanding Your Creative Options

One of the strongest points of the PEN E-PL1s is its Micro Four Thirds mount, giving access to a vast universe of over 100 native lenses from Olympus and other manufacturers like Panasonic and Voigtländer.

This opens creative possibilities from ultra-wide landscapes, pro-grade fast primes for portraits, macro lenses for close-ups, to telephoto zooms for wildlife.

The TG-310, conversely, has a built-in zoom lens fixed at 28-102mm equivalent (3.6x optical zoom), F3.9-5.9 aperture - versatile for casual shooting but not expandable.

Battery Life and Storage: Powering Your Shoots

• Olympus E-PL1s: Battery rated around 290 shots per charge using BLS-1 pack; uses SD/SDHC cards.
• Olympus TG-310: Smaller battery rated 150 shots; also uses SD/SDHC/SDXC.

In real shooting conditions, the PEN sustains longer shooting sessions, useful on extended hikes or event photography. The TG’s shorter battery life reflects its compact form and smaller battery capacity.

Both cameras accommodate a single card slot, standard for their classes.

Connectivity and Extras: Sharing and Workflow Integration

Neither camera supports Bluetooth, NFC, or Wi-Fi connectivity natively.

• The TG-310 offers Eye-Fi card compatibility for wireless image transfer if you add a compatible card.
• The PEN has a USB 2.0 port and HDMI output for tethered use and direct playback on HDTVs.

Neither supports external microphones or headphones, limiting advanced video workflows.

Video Capabilities: Casual to Basic

Both cameras capture video at 1280x720p (HD) at 30fps in Motion JPEG format.

• The PEN’s manual exposure modes allow some control over aperture and shutter during video, while the TG-310 offers no manual video controls.
• Both lack stabilization modes optimized for video; stabilization is sensor-based and benefits stills more directly.
• Absence of microphone inputs or headphone jacks constrains audio quality control.

These cameras will serve casual video needs rather than professional filmmaking.
