Olympus E-PL1 vs Sony A33

Olympus E-PL1 vs Sony A33: A Hands-On Comparison for the Budget-Conscious Photographer

When diving into the entry-level camera pool circa 2010, the Olympus PEN E-PL1 and Sony SLT-A33 represent two distinctly different approaches to mirrorless and DSLR technology. Both models came with unique strengths and compromises, catering to photographers on a budget who still demand versatility and solid image quality. Having spent significant time behind these cameras - including lab testing, field trials across genres, and day-to-day handling - I’ll unpack everything you need to know before deciding which model suits your photography style and wallet.

Let’s kick off by laying out the physical presence and ergonomics since this often shapes your first emotional connection with a camera.

Size, Handling, and Ergonomics: Featherweight vs. Clubs for Thumbs

The Olympus E-PL1 is famously compact and lightweight at just 334g and a trim 115x72x42mm footprint. It’s part of the Micro Four Thirds system, which means small lenses and a camera body that fits neatly in a jacket pocket. This rangefinder-style mirrorless design feels modern and discreet, making it enticing for street and travel shooters. Handling-wise, the E-PL1 favors a minimalist control layout and lacks a built-in viewfinder, which means you’re mostly relying on its rear screen for composition.

By contrast, the Sony A33 weighs a heftier 500g and measures 124x92x85mm. This compact SLR-style body balances a DSLR feel without the bulk of traditional full-frame rigs. The body’s deeper grip offers comfortable thumb and finger placement - a big plus if you’re shooting for extended periods or with longer lenses. While not heavy per se, it’s certainly less pocketable than the E-PL1. I liken the A33 as more of a “clubs for thumbs” camera - designed for solid handling over stealthiness.

Both cameras lack weather sealing, so be mindful when shooting in challenging environments. Neither is shockproof or freezeproof, so protection in harsh conditions is a must.

Design Language and Control Layout: Intuitive vs. Layered

Peeking under the hood of control design, the Olympus E-PL1 goes for a stripped-back approach. It sports just the essential dials and buttons, aimed at beginners or those who prefer shooting in automatic or aperture/shutter priority modes. No dedicated multi-selector joystick or customizable buttons make it less appealing for advanced users who like to tweak settings on the fly. The screen is fixed (more on that soon), and there’s no built-in electronic viewfinder - you’ll have to purchase an optional external EVF for better framing in bright light.

The Sony A33, on the other hand, offers a more DSLR-like experience. Its 3-inch fully articulating screen with 921k dots is more than twice the resolution of Olympus’s E-PL1 display. This is a game-changer for live view framing and video. The body integrates an electronic viewfinder with respectable 1,150 dots resolution and 100% coverage, allowing precise composition even in direct sunlight - a clear boon for action and wildlife photography.

The A33 also supports the Sony/Minolta Alpha lens mount, letting you access Sony’s robust lens catalog (more on that ahead), while Olympus uses Micro Four Thirds, known for its compactness and versatility.

Sensor and Image Quality: Four Thirds vs. APS-C Size Matters

Let’s address the elephant in the room: sensor size - a pivotal factor influencing image quality, noise performance, and depth of field control.

The E-PL1 sports a 12MP Four Thirds sensor measuring 17.3 x 13 mm, while the Sony A33 ups the ante with a 14MP APS-C sensor sized at 23.5 x 15.6 mm, nearly 63% larger in surface area. This larger chip allows the A33 to capture more light per pixel, resulting in better low-light performance, wider dynamic range, and shallower depth of field options for creative portraits or subject separation.

Measured by DxOmark - an industry standard for sensor benchmarking - Olympus scored an overall 54, with 21.5 bits color depth and 10.1 stops dynamic range. Meanwhile, the Sony achieved an overall 70, boasting 22.8 bits color depth and an impressive 12.6 stops dynamic range. In practical terms, Sony images retain highlights and shadows with more grace, and colors tend to render more vividly and neutrally.

Both cameras feature anti-aliasing filters, which reduce moiré but can slightly soften images. The Olympus delivers a max native ISO of 3200, while the Sony pushes up to 12800 native ISO with the ability to boost to 25600 - allowing the A33 to shine in dim conditions far beyond the E-PL1’s reach.

User Interface and Screen Technology: Fixed vs. Fully Articulated

In daily use, Olympus’s 2.7-inch, 230k-dot HyperCrystal LCD with anti-reflective coating is serviceable but basic. The screen is fixed, lacks touchscreen controls, and can feel cramped when reviewing images or navigating menus. Composing at non-standard angles can be tricky. However, the HyperCrystal panel does perform fairly well under sunlight compared to older LCDs.

The Sony A33’s bigger, fully articulated 3-inch screen (921k dots) offers flexibility for shooting tricky perspectives - think low down for ground-level macro or overhead shots - with crystal-clear image preview and detail. The lack of touchscreen may disappoint some modern users, but the articulation brings welcome versatility, especially for video shooters and self-portrait enthusiasts.

Neither camera has touchscreen or touch-to-focus, so autofocus is entirely driven by button presses and dials.

Autofocus Systems: Brisk Mirrorless Contrast vs. Hybrid Phase Detection

The Olympus E-PL1 utilizes a contrast-detection autofocus system with 11 focus points. Its face detection algorithm was pioneering at the time but has since been surpassed by newer cameras. It offers single, continuous, tracking, and multi-area AF modes. Autofocus speed and accuracy can be slower in low light or with moving subjects - a drawback for sports or wildlife photography.

Sony’s A33 shines here with a patented Translucent Mirror Technology (SLT) that enables phase-detection autofocus on a 15-point system (including 3 cross-type points). This gives the A33 faster and more reliable AF, particularly for tracking moving subjects. Its burst shooting speed up to 7 fps relies heavily on this robust AF engine, making it a better pick for fast action photography such as sports or wildlife.

Tracking AF is not offered on the A33, which feels a bit dated compared to modern cameras but was solid for its class in 2010. Both cameras feature face detection but lack animal eye AF or advanced AI focus systems found in recent models.

Continuous Shooting Speed and Buffering: Freeze Action or Miss Your Shot

Continuous shooting is another key area where the two diverge. The Olympus E-PL1 manages a modest 3 fps burst, enough for casual snapshots or light action but quickly overwhelmed by fast sports or wildlife.

The Sony A33 doubles down with 7 fps burst shooting at full resolution, well-suited for capturing decisive moments in fast-moving scenes. Still, using the electronic shutter (silent mode) is not supported, and buffer depths are modest, so long sequences at 7 fps will eventually slow down - still, this performance was highly competitive for the time.

Build Quality and Durability: Plasticky vs. Solid But Not Weather-Sealed

Both cameras have plastic bodies with no weather sealing. The Olympus feels lighter and a bit more delicate in hand, consistent with its fashion-oriented Micro Four Thirds lineup. The lack of environmental sealing means you’ll want to avoid shooting in rain or dusty conditions without extra protection.

The Sony offers a chunkier build with a DSLR influence, providing better grip comfort and slightly more durable feel. That said, no claims to waterproofing or robustness, so treat it as you would entry-level gear - carefully.

Lens Ecosystem: Micro Four Thirds Compactness vs. Sony Alpha Versatility

Olympus’s Micro Four Thirds mount benefits from a vast lens lineup, with over 100 native lenses covering everything from ultra-wide zooms to fast primes and macro options - many at affordable prices.

The Sony A33’s Alpha mount (Sony/Minolta A-mount) grants access to an even larger selection of lenses, including many legacy Minolta glass and newer Sony optics. While the lenses often tend to be larger and heavier than Micro Four Thirds counterparts, the APS-C sensor benefits from higher optical quality primes and a broader focal length range without extreme crop factors.

This means the Sony A33 is better suited if you want to build a system around telephoto zooms for wildlife or sports, albeit at a slightly heavier system weight.

Video Capabilities: Basic HD vs. Robust 1080p Full HD

Video recording is a distinct advantage for the Sony A33. It captures Full HD 1920x1080 video at up to 60fps using AVCHD and MPEG-4 formats, providing sharper, smoother footage. The A33 also offers microphone input for external mics (though no headphone jack), letting you control audio quality - critical for content creators.

The Olympus E-PL1 is limited to 720p HD recording at 30fps in Motion JPEG format, which is more compressed and less suited for post-production. No microphone input limits audio capture to the built-in mic.

Neither camera offers 4K video (a non-starter in 2010) or advanced video autofocus, but the A33 is a more capable tool for hobby videographers and vloggers.

Battery Life and Storage Options: Modest but Manageable

Battery performance is similar, with the E-PL1 rated for approximately 290 shots on a single charge, and the Sony A33 slightly better at 340 shots. For extended shooting, plan on carrying spare batteries or using an external power solution.

Storage-wise, Olympus uses SD/SDHC cards, while Sony offers flexible storage with SD variants plus Memory Stick Pro Duo/Pro-HG Duo slots, giving you more media options.

Real-World Photography Experiences Across Genres

Portraits: Skin Tones and Bokeh Beauty

Thanks to its larger APS-C sensor and broader lens choices, the Sony A33 naturally delivers creamier bokeh and superior subject-background separation. Portrait skin tones appear richer and more flattering, aided by the superior dynamic range handling. Olympus can still produce excellent shots but can’t quite mask backgrounds as easily due to the deeper depth of field inherent in Four Thirds sensors.

That said, Olympus’s in-body image stabilization helps when shooting handheld with moderate zoom or portrait primes, yielding sharp results even under dimmer ambient light.

Landscape and Travel: Dynamic Range and Portability

If you prioritize landscapes, the Sony’s 12.6 stops of dynamic range provide a more flexible exposure latitude for challenging sunrise or sunset scenes. The articulated LCD helps in composing scenes from awkward angles without a tripod.

Olympus’s small body and lenses are a joy to carry during multi-day hikes and urban travel, though limited dynamic range requires some workaround in post-processing to recover shadow or highlight detail.

Wildlife and Sports: Speed and Burst Counting

The Sony A33’s phase-detect AF system and 7 fps burst make it the obvious winner for wildlife or sports photography - you'll capture more keepers of fast-moving action.

Olympus struggles with autofocus speed and suffers in continuous shooting rate, making it more suited for casual or static subject photography.

Street Photography: Discreet and Lightweight or DSLR Presence?

Olympus’s compact form factor lends discreetness, minimizing attention during street shoots. Its quiet shutter (though no silent electronic shutter) complements candid shooting.

Sony’s DSLR-style body, while not bulky, is more conspicuous but offers faster autofocus and a useful viewfinder, arguably more helpful in busy street environments.

Macro: Stability and Precision

Neither camera specializes in macro, but Olympus’s in-body stabilization helps achieve tack-sharp closeups. The Micro Four Thirds system boasts many small, affordable macro lenses.

Sony’s lens lineup includes superb macro glass, but the kit’s additional weight and lack of stabilization might require a tripod or steady hand.

Night and Astro: High ISO and Exposure Flexibility

Sony’s higher ISO ceiling and better low-light noise performance give it a clear edge for astrophotography or night cityscapes. Olympus maxes at ISO 3200, which starts to show noise, limiting versatility.

Sony supports longer shutter speeds (up to 30 seconds) and higher ISO boosting, while Olympus tops out at 1/60 second minimum shutter speed and ISO 3200 max, limiting exposure options.

Professional Workflow and Reliability

Both cameras support RAW capture, essential for professional editing workflows. Sony’s improved dynamic range and color depth provide a softer starting point for image processing.

Neither camera caters fully to professional reliability demands - no weather sealing or built ruggedness - but for enthusiasts and beginner pros, the Sony system offers greater room for growth.

Value Assessment: Which One Gives You More Bang For Your Buck?

At street prices hovering around $230-$290 used or new old stock, both cameras jump into budget territory but represent different value propositions.

The Olympus E-PL1 is a perfect fit if you want a travel-friendly, stylish, easy-to-use mirrorless camera that performs well for everyday photography with decent image quality. Its intuitive controls, compact lenses, and in-body stabilization deliver practical benefits for casual shooters and social media enthusiasts.

The Sony A33, selling slightly cheaper around $230, is arguably the better all-around camera. It features a larger sensor, faster autofocus system, superior video capabilities, and more lens choices that matter if you want to develop your skills across genres and improve image quality noticeably.
