Olympus E-P2 vs Sony T99: A Real-World Camera Showdown for the Serious and the Casual

Choosing a camera can feel like jumping into a sea of confusing specs and marketing hype. Today, I’m bringing clarity by comparing two very different cameras from 2010 - the Olympus PEN E-P2, a rangefinder-style mirrorless camera aimed at enthusiasts looking for versatility and image quality, and the Sony Cyber-shot DSC-T99, an ultracompact point-and-shoot designed for casual users who prioritize convenience and pocketability.

Having personally tested thousands of models over the years, including many entry-level mirrorless and ultracompact cameras, I know what works and what falls flat in real-world use. Throughout this comparison, I’ll break down the strengths and compromises of each, highlight who stands to benefit most, and share my hands-on impressions from trying both through varied photography disciplines.

First Impressions: Size, Feel, and Handling

Let’s start where any real-world experience starts - with how the cameras feel in the hand and fit into your lifestyle.

The Olympus E-P2 is nicely balanced for a mirrorless, sporting a classic rangefinder look with controls that invite deliberate operation. It measures about 121 x 70 x 36 mm and weighs 355 grams. Not exactly pocketable, but it slips comfortably into a small bag. The camera’s Micro Four Thirds mount offers a true enthusiast’s lineup potential, supporting over 100 lenses - a serious lens ecosystem for growth. The fixed 3-inch HyperCrystal LCD is clear and responsive enough for framing and review, albeit without touch input.

In contrast, the Sony T99 is an ultracompact marvel, measuring a tiny 93 x 56 x 17 mm and tipping the scales at just 121 grams. This one fits in your jeans pocket, ready to grab and shoot on the spur of the moment. Its fixed lens and complete lack of manual exposure modes reflect its design focus on simplicity. The 3-inch touchscreen is adequate and adds modern convenience but can feel cramped when quickly navigating menus.

Ergonomically, the E-P2 invites the photographer to engage with settings manually. The T99 appeals to those who want point-and-shoot ease. These differences highlight the cameras’ contrasting philosophies.

Under the Hood: Sensor and Image Quality

At the core of any good camera is its sensor - it's the electronic eye that captures your memories.

The Olympus E-P2 houses a 12MP Four Thirds-sized CMOS sensor measuring 17.3 x 13 mm, with a sensor area of roughly 225 mm². This is considerably large for its class, enabling better image quality, especially in challenging light conditions. Olympus includes an anti-aliasing filter and TruePic V image processor, designed to offer natural colors and sharpness with an overall DxOmark score of 56 - a respectable rating indicative of solid color depth (21.5 bits) and dynamic range (10.4 EV).

Meanwhile, the Sony T99 utilizes a smaller 1/2.3" CCD sensor, just 6.17 x 4.55 mm (28 mm²), with 14MP resolution. On paper, it offers higher pixel count, but smaller sensor size translates to generally lower image quality, higher noise at elevated ISOs, and less impressive dynamic range. Sony’s Bionz processor handles image rendering, but it can't fully overcome the physical limits of its small sensor. Importantly, the T99 lacks RAW support, meaning JPEGs are your only option, restricting post-processing flexibility.

Real-world takeaway: The E-P2's larger sensor and RAW capability deliver cleaner, more detailed images with better tonal gradation - a key advantage for enthusiasts and professionals. The T99 is fine for casual snapshots but won’t satisfy anyone needing high-quality files.

Autofocus and Shooting Performance

Autofocus (AF) might sound like technical gobbledygook, but it directly affects how quickly and accurately your camera locks onto subjects - a crucial factor when capturing fleeting moments.

The Olympus E-P2 employs a contrast-detection AF system with 11 selectable focus points, face detection, and live view capabilities. While lacking phase detection (still uncommon in 2010 mirrorless), it offers decent single and continuous AF modes. Unfortunately, continuous tracking is absent, which can hamper action photography. Still, a 3 fps burst rate isn’t bad for entry-level mirrorless from this era.

The Sony T99, true to its ultracompact nature, uses a simpler contrast AF system with 9 focus points and center-weighted focusing. Face detection is missing, and autofocus is relatively slower, especially in low light. However, this camera delivers a 10 fps burst mode at maximum 6MP resolution during its “multi-shot” mode, mainly intended for casual use - not professional sports.

Real-world impact: If you’re into portraiture or static subjects, both cameras can keep up. For wildlife or sports photography, the Olympus’ autofocus system and continuous shooting better support fast action capture, but neither setup would thrill a pro shooter.

Viewfinder and LCD Screen: Composing Your Shot

Great composition depends on what you see through your viewfinder or on your LCD.

Neither camera includes a built-in viewfinder, but the E-P2 can optionally connect to an electronic viewfinder - a boon for bright environments or more stable framing. Both feature a fixed 3-inch LCD with 230k dots resolution; the E-P2’s screen uses HyperCrystal tech with anti-reflective coating to enhance visibility, especially outdoors.

The Sony T99’s touchscreen is convenient for browsing and quick adjustments, but less suited to traditional operation modes favored by photographers who prefer physical dials and buttons.

Lens Ecosystem and Versatility

Here’s where the gap widens dramatically: lens options and compatibility.

The Olympus E-P2 uses the Micro Four Thirds mount, which has exploded into a substantial, mature system with over 100 lenses available - from ultra-wide primes and fast portraits to high-powered telephotos and professional macro optics. My personal testing across multiple MFT lenses has shown excellent image quality, aided by in-body sensor stabilization.

The Sony T99 ships with an integrated 25-100mm f/3.5-4.6 zoom (35mm equivalent 145-580mm), fixed to the body. While impressively compact, this fixed lens limits creative framing and depth-of-field control. There’s no option to swap lenses to suit different photographic pursuits.

If you want adaptability with focal lengths and optical quality upgrades, Olympus wins hands down.

Build Quality and Durability

Neither is ruggedized, but build quality nuances matter.

The E-P2 feels solidly built with a metal body and a pleasing heft. While lacking official weather sealing, its construction is sturdy for cautious handling outdoors.

The T99, designed as a pocketable carry-along, sports a plastic shell and feels more delicate. It’s perfect for quick snaps but not for demanding conditions.

Battery Life and Storage

For regular shooting, battery life is a serious concern.

The Olympus E-P2 uses a rechargeable BLS-1 battery providing about 300 shots per charge - modest but manageable for day shoots. It stores images to standard SD or SDHC cards. One card slot keeps things simple but limits redundancy.

The Sony T99’s tiny NP-BN1 battery capacity isn’t officially rated, but testing shows it rarely survives a full day of moderate shooting. It supports SD/SDHC/SDXC and proprietary Memory Stick formats, plus internal storage - a convenience for quick transfers or emergency memory.

Video Capabilities

Neither camera would be described as video maestros.

Both capture 720p HD video at 30fps, with basic codecs (MJPEG on E-P2, MPEG-4 on T99). Neither supports external microphones or headphone monitoring, limiting serious audio work. The Olympus fares slightly better with manual exposure control during recording and a clean HDMI output.

For occasional video clips, both suffice. For content creators craving high-quality footage, modern alternatives may be wiser.

Specialized Photography Uses

Let’s see just how these cameras behave across common photography genres and assignments.

Portraits

The E-P2 boasts face detection, 11 AF points, and larger sensor advantages that translate to natural skin tones and pleasing bokeh with fast lenses. I've shot portraits with the E-P2 handheld, capturing crisp, creamy backgrounds thanks to Micro Four Thirds optics paired with sensor-based stabilization.

The T99’s smaller sensor and fixed lens lead to deeper depth of field and less flattering subject-background separation. Its lack of face detection hampers consistently sharp focus on eyes.

Landscapes

The E-P2’s sensor and dynamic range excel here, delivering detailed textures and vibrant colors in raw or JPEG form. Weather sealing absence requires caution outdoors.

The T99 suffices for casual snaps but struggles with dynamic range, often clipping shadows or highlights.

Wildlife and Sports

Neither is optimized for fast action, but the E-P2’s continuous AF and burst shooting fare better. The T99’s slow shutter ceiling (~1/1250s max) and lack of AF tracking are limiting.

Street Photography

This is the T99’s comfort zone - stealthy, quick, and pocketable. The E-P2 is bulkier and quieter, but adaptable if street style shooting is deliberate.

Macro

The Olympus’s interchangeable lenses and sensor-stabilization enable impressive close-ups. The Sony is limited to its built-in macro capability (~1cm minimum focus), adequate for casual detail shots but less versatile.

Night / Astro

The E-P2’s larger sensor and ISO ceiling of 6400 allow cleaner images in low light and starry skies. The T99’s CCD sensor and max ISO 3200 mean noisy, soft results.

Travel

The T99’s size and quick start-up suit travel snapshots. The larger E-P2 offers more creative control for travel photographers willing to carry extra gear.

Professional Work

The E-P2 supports RAW format, manual controls, and a robust workflow pipeline, aligning better with professional needs. The T99 is purely snapshot territory.

Sony’s touchscreen and simplified menus cater to beginners or convenience lovers. It supports Eye-Fi wireless card connectivity, handy for instant sharing - a nod to casual social media users.

Neither offers Bluetooth or GPS - a limitation by today’s standards but typical of the era.

Price and Value Considerations

Retail pricing at launch was approximately $799 for the Olympus E-P2 and $179 for the Sony T99 - a stark difference, reflecting their intended audiences and technology levels.

For those budget-conscious or needing a pocket camera for snapshots, the Sony provides excellent value with easy operation.

For enthusiasts seeking image quality, manual controls, and a future-proofed lens system, the Olympus justifies the higher outlay.
