Olympus PEN E-PL2 vs Sony Cyber-shot DSC-T99: A Hands-On Comparison for Real-World Photography

Choosing the right camera often means balancing a thoughtful mix of size, image quality, usability, and versatility. Today, I’m diving into two very different cameras from around the same era - the Olympus PEN E-PL2, a Micro Four Thirds mirrorless system camera touted for entry-level enthusiasts, and the Sony Cyber-shot DSC-T99, a sleek ultracompact point-and-shoot designed for casual clickers. With over 15 years reviewing cameras, I’ll share how each performs across key photography types, assessing them through technical specs and more importantly, real-world shooting experience. By the end, you’ll have a clear sense of which suits your style and budget.

First Impressions: Size, Build, and Handling Matter

Before pixel-peeping, let's talk feel. After all, a camera in hand shapes your shooting mood more than any spec sheet.

The Olympus E-PL2 sports a rangefinder-style mirrorless body with a solid, almost retro charm. Weighing 362g and measuring 114x72x42mm, it strikes a balance - not too small to handle comfortably, but still light and compact compared to DSLRs. Olympus’s use of a metal chassis lends a reassuring sturdy feel, though it lacks full weather sealing. The fixed 3-inch HyperCrystal LCD is bright, with an anti-reflective coating that helps in outdoor daylight.

On the flip side, the Sony T99 is ultra-compact and pocket-friendly at just 121g and a svelte 93x56x17mm, fitting easily into a jeans pocket. The design is minimalistic, slick, almost candy-bar like, with a 3-inch touchscreen LCD - a rarity in this class back in 2010. Its body is plastic but well-finished for an everyday carry.

Handling wise, the E-PL2’s design favors photographers who want better grip and manual control, while the T99 caters to those prioritizing portability and simplicity. If you prefer a camera you can tuck anywhere yet still operate quickly, Sony’s T99 has the edge. But if you want more shooting control and interchangeable lenses, the Olympus feels like a more serious tool.

Sensor and Image Quality: The Heart of the Camera

Image quality is where the E-PL2 and T99 diverge dramatically, mainly due to sensor size and design choices.

The E-PL2 houses a 12MP Four Thirds (17.3x13mm) CMOS sensor. While a 12MP resolution might feel modest today, in 2011 this sensor size offered a good balance of detail, dynamic range, and noise levels, especially compared to smaller sensors in compact cameras. Olympus paired this sensor with the TruePic V processor, delivering reasonably clean images up to ISO 3200, with usable results even at ISO 6400 for less demanding uses.

Sony’s T99 comes with a 14MP 1/2.3" (6.17x4.55mm) CCD sensor, substantially smaller. While the higher megapixel count might initially impress, the small sensor area limits dynamic range and low-light performance. Noise creeps in quickly past ISO 400, and tonal gradations suffer compared to larger sensors.

In my lab tests and field shoots, the E-PL2 consistently delivers sharper, less noisy images with more natural colors and deeper shadows retained. The T99 tends to produce softer images, with higher noise and reduced dynamic range - typical traits of small sensor compacts from that era. However, in bright daylight or casual snapshots, the T99's sensor still preserves reasonable detail.

If your priority is image quality and post-processing flexibility (RAW support is only present in the E-PL2), the Olympus system camera clearly leads here. Image files from the E-PL2 also handle skin tones and highlights with better fidelity - key for portraits and landscape work.

Controls and User Interface: Intuitive or Minimalist?

Moving beyond raw specs, how does it feel to operate these cameras?

The Olympus E-PL2 brings classic exposure controls like aperture priority, shutter priority, and manual modes - all essential for creative photographers. A modest continuous shooting speed of 3fps fits entry-level use, not sports action. Focusing is contrast-detection based, with 11 focus points including face detection, and features such as AF tracking and selective AF areas. The physical control layout includes dedicated dials and buttons making adjustments straightforward. The rear LCD is fixed (not tilting) but crisp and responsive.

The Sony T99, being a compact, has pared-down controls lacking manual exposure modes, shutter priority, or aperture priority - all automatic and program modes. It does, however, offer a touchscreen interface for focus and shooting, which was quite novel then. Continuous shooting tops out at 10fps but limited to small buffer sizes and slower write speeds.

The lack of manual controls on the Sony might frustrate enthusiasts craving creative freedom, while beginners will appreciate its simplicity and touchscreen responsiveness. Olympus feels more traditional and rewarding for photographers seeking hands-on control.

Lens Systems and Versatility: Beyond the Body

This is arguably the defining difference between these two cameras.

The Olympus E-PL2 uses the Micro Four Thirds mount, compatible with over 100 lenses ranging from wide-angle primes to super-telephoto zooms. This vast ecosystem opens doors to specialized photography including macro, telephoto wildlife, and portrait lenses with creamy bokeh. Moreover, many third-party lenses add creative options.

In contrast, the Sony T99 is a fixed-lens camera with a 25-100mm equivalent zoom and maximum aperture f/3.5–4.6. It covers the basics but limits any optical upgrade, making it a strictly casual camera.

If you’re passionate about exploring different genres and demand system expandability, Olympus has the decisive advantage. Sony’s fixed zoom ensures portability but confines you to a single-use scenario.

Autofocus Performance and Burst Shooting

Autofocus is critical for sports, wildlife, and street photography.

The contrast-detection AF system in Olympus’s E-PL2, with face detection and AF tracking, performs well in daylight and moderate lighting. It’s responsive, though not as rapid as today’s phase-detection systems. The 3fps burst rate is modest, sufficient for casual action but underpowered for fast sports or bird-in-flight scenarios.

Sony’s T99 uses a contrast-detection AF with 9 points but lacks face detection or tracking. It’s slower and less precise - noticeable if subjects move quickly. The 10fps continuous shooting burst looks good on paper but practical throughput is limited by slow buffer clearing and smaller sensor readout speeds.

For wildlife and sports enthusiasts who need reliable AF speed and tracking, neither camera excels, but Olympus is the better pick if you must choose these two.

Portrait Photography: Skin Tones and Bokeh

Let’s see how these cameras handle one of the most popular genres - portraits.

Olympus with its larger sensor and interchangeable lenses can offer shallow depth of field, producing smooth bokeh separating the subject from background. Its color science handles skin tones softly and naturally, with good exposure latitude to retain highlight details on faces. Face detection AF works well to keep your subject sharp, and manual controls help finesse settings.

Sony’s smaller sensor imposes a deep depth of field, making background blur minimal even at the longest zoom. Skin tones can appear less natural due to limited dynamic range and image processing optimizations favoring saturation and contrast over subtlety. Without face detection, focus precision relies on your framing and focus point selection only.

If portraits are your thing, Olympus is the clear winner here, since nothing beats sensor size and glass choice for flattering images.

Landscape Photography: Resolution, Dynamic Range, and Build

For landscapes, dynamic range and resolution are paramount to capture vast tonal gradations.

Olympus’s 12MP sensor coupled with its larger pixel pitch yields superior dynamic range - rated around 10.2 EV at base ISO - preserving details in shadow and highlight. The 4:3 aspect ratio suits traditional landscapes well. Lack of weather-sealing is a downside, so caution is advised in adverse weather.

Sony’s tiny 1/2.3" sensor fumbles a bit, with limited dynamic range and more noise in shadows, especially under harsh lighting transitions. However, the 14MP resolution, on paper, provides fine detail in good light, albeit with softness due to diffraction and the limitations of CCD technology. The compact body is very travel-friendly.

In practice, I preferred the Olympus for serious landscapes if conditions are controlled, though Sony could still capture some pleasing vacation snaps where portability is key.

Wildlife Photography: Telephoto Reach and Autofocus

The E-PL2’s lens ecosystem lets you attach telephoto zooms and primes with long focal lengths, a big help for distant subjects. Meanwhile, the T99’s lens equivalent maxes out at 100mm zoom. Factor in the Olympus’s 2.1x crop factor - tele lenses stretch even farther in equivalent field-of-view terms.

Autofocus for wildlife demands quick locking and tracking, especially for erratic subjects. Contrast AF on both cameras makes this a weak spot - Olympus edges out Sony with face detection and AF tracking.

Burst mode speed also favors Sony on paper with 10fps versus 3fps, but Olympus’s buffer handling and AF accuracy make the E-PL2 more trustworthy overall for wildlife.

In short, casual wildlife snaps? Either works, but Olympus paired with a telephoto lens offers far better reach and sharper images.

Sports Photography: Tracking and Low-Light Frame Rates

Sports photographers need snappy autofocus, high burst rates, and good low-light capability.

Neither the Olympus E-PL2 nor Sony T99 was designed with high-speed sport in mind. Olympus’s contrast-detection AF and 3fps burst limit action captures, while Sony’s 10fps burst is handicapped by a slower shutter range and limited AF accuracy.

Low ISO performance on Olympus is comparatively better, making it more suitable for indoor sports or evening events. The Sony struggles with noise at its max ISO of 3200 (vs Olympus 6400).

If shooting regular sports events is your goal, look beyond these two - but if forced to pick, Olympus is a better fit for casual shooting.

Street Photography: Discretion and Low-Light

Street photographers prize discretion, portability, and fast responsiveness.

Sony’s pocketable size and quiet operation make it ideal for candid shooting on the go. Its shutter speed tops out at 1/1250s - less than Olympus’s 1/4000s max - which might limit freezing very fast street scenes.

The E-PL2’s larger body and lens combos make it less stealthy. However, improved manual control, better low-light IQ, and face detection give it an edge for more serious street portraits.

Depending on your style - great candid snapshots with a pocket shooter, or artistic deliberate shots - either camera can fit. Sony excels in portability; Olympus in control and image quality.

Macro Photography and Close-Up Focus

Close focusing capability and stabilization matter hugely for macro.

Olympus offers sensor-based image stabilization (5-axis in later models, but the E-PL2 has basic sensor-shift IS), assisting handheld macro shots. The Micro Four Thirds mount supports a variety of dedicated macro lenses, with high magnifications and fine focusing.

Sony’s T99 offers a 1cm macro focus mode at wide angle, useful for casual close-ups but limited by its fixed optics and no IS.

For macro enthusiasts, the Olympus system has immense flexibility and superior stabilization.

Night and Astrophotography: High ISO and Exposure Modes

Night shooters demand clean high ISO, long exposure abilities, and maybe bulb mode.

Olympus’s ISO extends to 6400, with moderate noise control. The sensor and shutter support exposures up to 60 seconds, crucial for astrophotography. Bulb mode, while unofficial on E-PL2, can be contrived via manual settings.

Sony’s max ISO is 3200, with limited long exposure capabilities (max shutter speed 2 seconds). No manual exposure modes restrict its usefulness for night work.

If you want to dive into night landscapes or star fields, Olympus is worthwhile; Sony is more for casual snapshots after dark.

Video Capabilities: Resolution and Features

Both cameras output 720p HD video at 30fps, but with nuanced differences.

Olympus E-PL2 records Motion JPEG format, easier for quick editing but larger file sizes. The camera lacks microphone and headphone ports and optical image stabilization during video is disabled.

Sony’s T99 video is MPEG-4 format at 720p 30fps, with Optical SteadyShot helping smooth footage - a real boon. A microphone input, though desirable, is also absent here.

The touchscreen on Sony simplifies focus during video, whereas Olympus requires manual focus ring use or contrast AF hunting.

Overall, neither camera is a video powerhouse, but Sony’s smoother handling and image stabilization makes casual video easier.

Travel Photography: Battery, Storage, and Portability

Travelers juggle weight, versatility, and battery life.

Olympus offers a respectable battery life of around 280 shots per charge, typical for mirrorless early models. Single SD card slot for storage. At 362g, plus lenses, it’s heavier but highly versatile.

Sony’s tiny body excels in weight and size, with a very small footprint. Battery life data is sparse, but generally compacts run shorter life on smaller batteries. Multiple storage formats (SD and Memory Stick) add flexibility.

If your priority is minimal gear and light pack, go Sony; for better image quality and flexibility, bring Olympus.

Professional Work and Workflow Considerations

Neither camera targets high-end professional workflows, but Olympus’s RAW file format support is definitely a plus. RAW processing allows serious postproduction and color grading. The Sony T99 only shoots JPEGs.

Olympus supports USB 2.0 and HDMI output for tethering and previews. Sony lacks HDMI output. Neither offers wireless connectivity except Sony’s Eye-Fi card compatibility.

Professionals wanting a budget system for experimental or backup use will favor Olympus.

Pricing and Value: Old Models, New Insights

Both models are discontinued, often found used or refurbished.

The Olympus E-PL2, as a Micro Four Thirds system camera, often commands higher secondhand prices - but the investment opens vastly more photographic possibilities.

The Sony T99 may be found cheaply, ideal for beginners seeking casual snapshot convenience.
