Olympus E-PL1 vs Sony A99: An Expert’s Journey Through Two Different Eras and Ambitions

Digital cameras have evolved dramatically over the last decade, bringing new sensor technologies, autofocus systems, and ergonomic refinements, all tailored to satisfy a broad range of photographic appetites. Today, I’m diving into a head-to-head comparison between two intriguing representatives from very different corners of this evolution: the Olympus PEN E-PL1, an entry-level mirrorless from 2010, and the Sony SLT-A99, an advanced semi-professional DSLR introduced in 2012. Both have their place in history and in certain shooting styles, yet they couldn’t be more different in execution and ambition.

Having extensively handled both cameras, alongside thousands of other gear over the years, I’m here to offer you a detailed, balanced, and practical analysis. No fluff here - just my hands-on experience combined with solid technical know-how. So buckle up, and let’s start by putting these two devices side-by-side.

First Impressions: Size, Weight, and Ergonomics

Before we get lost in specs and pixels, a picture is worth a thousand words. Literally - let’s eyeball their physical presence:

The Olympus E-PL1 tips the scales at a dainty 334 grams with dimensions of 115x72x42mm. In contrast, the Sony A99, weighing a solid 812 grams and sized 147x111x78mm, is more than twice as heavy and significantly chunkier.

This size and weight discrepancy tell us a lot about the intent behind each camera. The E-PL1 is designed with portability and casual ease in mind - perfect for photographers who like to travel light or want a straightforward introduction to mirrorless systems. The Sony A99, meanwhile, feels like it’s ready to be your beefy workhorse for professional use - demanding more bag space but offering robust handling that’s comfortable for extended shoots.

Looking further into the control layout and top plate, here’s what they bring to the table:

The A99 sports a conventional DSLR-style layout but also includes the translucent mirror system unique to Sony's SLT design - blending some features from mirrorless tech with traditional DSLR ergonomics. The expansive mode dial, dedicated ISO and exposure compensation buttons, dual command dials, and a large grip deliver quick access and stability. Olympus’ E-PL1 seeks simplicity, catering mostly to amateur shooters, with fewer dedicated buttons and smaller dials - which can feel cramped in hands used to more advanced rigs. But don’t underestimate its charm for beginners or casual street shooters craving less bulk.

Recommendation: If portability with decent handling is your focus, the Olympus is a winner. But for photographers who need control at their fingertips and confidence in the grip during long sessions, Sony’s A99 delivers.

Sensor Size and Image Quality: The Heart of the Matter

The sensor is arguably the most critical component impacting image quality, depth of field control, dynamic range, and noise performance. Here’s a direct comparison:

• Olympus E-PL1: Four Thirds sensor, 17.3x13 mm, 12 MP native resolution
• Sony A99: Full-frame sensor, 35.8x23.8 mm, 24 MP native resolution

The Sony A99’s sensor is nearly 4x larger in surface area than the Olympus’, meaning bigger pixels and inherently better light-gathering ability. This translates to superior dynamic range, richer color depth, and lower noise, especially in low-light conditions.

The image quality metrics underpin these advantages. On DxOMark, the A99 scores an impressive 89 overall, showcasing a fantastic balance of resolution (24 MP), color depth (25.0 bits), and dynamic range (14 stops). The E-PL1’s score is a modest 54, sufficient for casual shooting but showing limitations in highlight and shadow detail preservation and noise handling at higher ISOs.

Real-world impact:

• In portraits and landscapes, the Sony’s sensor provides exquisite skin tone gradations and striking dynamic range, even under tricky lighting.
• Olympus’ smaller sensor struggles more with noise beyond ISO 800 and reveals less tonal subtlety.

That said, the E-PL1’s 12-megapixel resolution paired with the Micro Four Thirds lens ecosystem offers crispy details at reasonable print sizes and makes for smaller, lighter packages that photographers value.

LCD Screen and Viewfinder: Your Window into the Image

User interface is often overlooked but crucial when photographing under various conditions. Take a look below:

The Olympus features a 2.7-inch fixed HyperCrystal LCD with a modest 230k-dot resolution - readable but basic by today’s standards. The lack of touchscreen and fixed positioning limit flexibility, especially for low or awkward angles.

Conversely, Sony’s A99 comes equipped with a fully articulated 3-inch TFT Xtra Fine LCD boasting over 1,200k dots, making it crystal-clear for reviewing shots and navigating menus. The articulation is a boon for overhead street shots, low macro work, and video recording.

Now, to compensate for the E-PL1’s lack of a built-in viewfinder, Olympus offered an optional external electronic viewfinder (EVF). I personally tried it, and while it helped in bright environments, it was a bit clunky to attach and less immersive compared to dedicated DSLR viewfinders.

The Sony A99 sports a high-res electronic viewfinder with 2359k dots, 100% coverage, and 0.71x magnification - delivering a bright, lag-free experience better suited for fast action, manual focusing, and precision framing.

Autofocus and Burst Shooting: Chasing the Moment

Autofocus systems are the unsung heroes of successful photography, particularly in wildlife and sports.

Here’s the gist based on hands-on testing:

Sony’s A99 employs a hybrid phase-detection AF system with 19 points (11 cross-type), enabling rapid, precise focusing during continuous shooting. This comes in particularly handy when shooting sports or wildlife where subjects move unpredictably.

The E-PL1 relies on an older contrast-detection AF system, which, while accurate in static scenes and suited to video live view, tends to be slower and hunts in low-contrast or fast-action scenarios. At 3 FPS continuous shooting, it simply cannot compete with the A99’s 10 FPS sensor readout.

In real-world wildlife or sports situations, I found the Sony A99 a reliable tracking companion, rarely losing focus on moving subjects even in challenging light. The Olympus occasionally required patience and steady hands - fine for street photography or casual portraits but limiting for high-speed action.

Lens Ecosystem and Compatibility

Two factors shape a camera’s optical future: native lenses available and mount versatility.

• Olympus E-PL1 uses the Micro Four Thirds mount. At launch, it had access to 107 lenses - a rapidly growing and now vast array of prime, zoom, macro, and specialty optics from Olympus, Panasonic, and third parties. This ecosystem’s strength lies in compact, high-quality lenses perfect for travel, macro, and portraiture with affordable price points.

• Sony A99 leverages the Sony/Minolta Alpha mount, itself a legacy from Minolta’s film SLR days. With 143 native lenses listed, including many professional-grade full-frame optics designed for Sony’s ALPHA system, its lens options cover everything from ultra-wide landscapes to super telephoto wildlife capabilities. Sony’s system compatibility with A-mount lenses and adapters for E-mount lenses widens versatility further.

If you value lightweight, compact kits and affordable glass, Olympus is compelling. However, if you aspire to comprehensive lens choices, including specialist sports and wildlife telephotos or fast primes, Sony’s mount offers more flexibility.

Build Quality and Weather Resistance

Handling and durability often count more for professional photographers who expose their gear to the elements or prolong usage.

• The Sony A99 features weather sealing to resist moisture and dust - essential in unpredictable conditions and outdoor shoots. The magnesium alloy frame and robust build instill confidence under strain, despite weighing over 800 grams.

• The Olympus E-PL1 does not claim weather sealing, sporting a predominantly polycarbonate body with a stylish but delicate feel. It’s better handled with some care, especially in adverse weather.

For adventure photographers, especially landscape and wildlife shooters, the A99’s ruggedness earns bonus points.

Battery Life and Storage

Battery life and storage capabilities determine how far a shoot can stretch without interruptions.

• Olympus E-PL1 offers around 290 shots per charge, adequate for casual outings but requiring spares for extended travels or events.

• Sony A99 clocks in at approximately 500 shots per charge, a solid increase, reflective of its larger body accommodating beefier cells.

The A99’s dual card slots (Memory Stick PRO Duo + SD cards) provide redundancy and flexibility - invaluable for professional workflows and backup.

Meanwhile, the E-PL1 relies on a single SD/SDHC slot, limiting simultaneous backups but sufficient for everyday use.

Video Features: Casual Clips or Semi-Pro Filmmaking?

If you’re a hybrid shooter dabbling in video, here’s a rundown:

• Olympus E-PL1 shoots 720p HD at 30 fps in Motion JPEG format - straightforward but outdated, with no microphone or headphone jacks. Enough for casual home videos but hardly professional.

• Sony A99 supports 1080p Full HD video at 60/24 fps with AVCHD, MPEG4, and H.264 compression, alongside microphone and headphone inputs. Although not the latest 4K beast, it makes the A99 capable of serious video work for interviews, short films, or multimedia journalism.
