Olympus E-300 vs Olympus OM-D E-M5: A Thorough Comparison for Discerning Photographers

Selecting between two venerable Olympus cameras - the classic E-300 DSLR and the advanced mirrorless OM-D E-M5 - requires a careful look at how these cameras perform across the board. Though belonging to the same brand family and sharing the Micro Four Thirds sensor format, these cameras are pitched at different eras and target audiences. Drawing on years of extensive hands-on testing and image evaluation, I’ll walk you through all the nuances, strengths, and compromises you can expect when choosing either model.

Let’s dive deep into their physical design, core imaging technologies, and genre-specific shooting capabilities before wrapping up with tailored recommendations.

Feeling Them in Your Hands: Ergonomics and Build Quality

The first impression often comes from holding a camera - does it nestle comfortably or demand extra effort to master?

The Olympus E-300 is a mid-sized DSLR with a solid, conventional plastic chassis typical of the mid-2000s. Measuring 147 x 85 x 64 mm and weighing 624 grams, it feels heftier and somewhat chunkier by today’s standards. Its SLR body style - complete with optical pentamirror viewfinder - lends the camera a familiar heft, which some photographers find reassuring for stability during handheld shooting, especially with larger lenses.

In contrast, the OM-D E-M5 is a 2012 mirrorless design with a more compact footprint at 122 x 89 x 43 mm and a trim 425 grams. The reduced size does not come at the cost of feel; Olympus managed a robust magnesium alloy body with full weather sealing - a big win for travel and outdoor shooters who demand durability without lugging heavy gear.

Control layouts also reflect their design philosophies. The E-300 sports simpler, more-spartan top plate controls, lacking the user customization options of more recent models. The E-M5 ups the ante with twin control dials, an easily accessible mode dial, and an articulated touchscreen LCD that tilts - a boon in tricky shooting positions.

Simply put: The E-M5’s ergonomics anticipate modern photography’s nuanced demands, while the E-300 is a sturdy relic for those preferring a straightforward SLR experience.

The Heart of the Matter: Sensor and Image Quality

No discussion would be complete without diving into the sensor technology powering image creation. Both cameras use Olympus’s Four Thirds sensor, with dimensions 17.3 x 13 mm spanning 224.9 mm² - smaller than APS-C or full-frame sensors but a balanced compromise for size and image quality.

Where they diverge sharply is resolution and sensor type. The E-300’s 8-megapixel CCD sensor was cutting-edge in 2005, initially pairing well with Olympus’s Zuiko lenses. It offers native ISOs of 100-400, extendable to 1600, but image noise rises noticeably at higher ISOs.

By contrast, the OM-D E-M5 boasts a 16-megapixel CMOS sensor paired with the TruePic VI processor, providing superior color fidelity, dynamic range, and high ISO performance. It stretches native ISOs from 200 up to 25,600, with usable low-light output well beyond the E-300’s capability. The sensor also supports various aspect ratios (4:3, 3:2, 16:9, 1:1), giving creative framing flexibility while also enabling cropping for different output formats.

In practical testing - shooting both cameras side by side on a sunny day landscape - the E-M5 rendered more detailed foliage and maintained highlight-to-shadow gradation far better than the E-300, which showed earlier clipping and less nuance in midtones.

Viewing and Composing: Optical vs Electronic Viewfinders

Framing your shot is the tactile, visual core of photography. The E-300 relies on a pentamirror optical viewfinder, which shows a direct optical image with limitations: no coverage percentage given, relatively dim in low light, and no exposure display overlay. The lack of electronic assistance means exposure diagnostics require an external light meter or LCD check.

On the other hand, the E-M5 boasts a bright, high-resolution 1,440K-dot electronic viewfinder (EVF) with nearly 100% framing coverage and 0.58x magnification. This EVF supports live exposure previews, histograms, and focus peaking, translating to better confidence and accuracy - especially in manually focused or exposure-challenging scenarios.

The rear LCDs reinforce this divide: the E-300’s fixed 1.8-inch screen with 134k-dot resolution pales beside the E-M5’s 3-inch, 610k-dot tilt-screen with touch capability. Live view on the E-M5 is fully featured, aiding composition and focusing in LG or video modes; the E-300 has none of these modern amenities.

Autofocus and Performance Under Pressure

When the shutter button beckons, how quickly and accurately do these cameras focus?

The E-300 employs a phase-detection system with just 3 focus points - basic even by its time’s standards. It supports single and continuous autofocus but lacks tracking or face detection, so moving subjects are hard to lock onto reliably.

The OM-D E-M5 moves autofocus into the modern era with both contrast-detection autofocus and 35 focus points, plus noteworthy face detection and continuous AF tracking modes. Embedded touch-to-focus on the LCD adds further precision, making it ideal for action, street, and wildlife photography.

Burst shooting rates also echo this leap: 3 fps max on the E-300 vs a brisk 9 fps on the E-M5, facilitating easier capture of fleeting moments.

Battery Life and Storage: Staying Power in the Field

The E-300 lacks official battery life specs here but traditionally runs on 4× AA batteries - a mixed blessing. A readily available power source is handy, but limited battery cycles constrain shooting duration.

The E-M5 uses the proprietary BLN-1 rechargeable battery, rated for around 360 shots per charge. While smaller than some DSLRs, it’s reasonable for mirrorless bodies, and the camera also supports USB charging - a convenience absent in the E-300.

Storage follows the evolution: Compact Flash (Type I or II) cards for the older E-300, SD/SDHC/SDXC cards for the E-M5. The ubiquity and speed of SD cards today tip the scales to the E-M5 for ease and performance.

Lens Compatibility and System Ecosystem

Both cameras use the Micro Four Thirds (MFT) mount system, offering cross-compatibility with a wide range of lenses. The E-300 was among the earliest Four Thirds system cameras, with approximately 45 lenses available at the time. The OM-D E-M5, reflecting the mature MFT system’s growth, benefits from over 100 lenses spanning Olympus, Panasonic, and third-party makers.

This expanded lens ecosystem includes fast primes, versatile zooms, ultra-wide lenses, macros, and specialty optics. Moreover, the native MFT format’s 2.1x crop factor delivers practical telephoto reach useful for wildlife and sports.

Genre-Specific Performance and Practical Usage

Examining practical genre applications highlights the honorable nuances each camera brings to the table.

Portrait Photography

Portrait work demands precise skin tone rendition, smooth bokeh, and reliable face/eye detection autofocus.

The E-300 handles skin tones well given its CCD sensor’s natural color palette but offers no face or eye detection autofocus, forcing careful manual focus or static subjects. Bokeh is lens-dependent, with no in-body stabilization, so out-of-focus backgrounds can appear noisy in low light.

The E-M5 shines here with its advanced autofocus and exposure control, plus 5-axis sensor-shift image stabilization that aids handheld shooting at wider apertures. Face detection and higher resolution provide crisp eye details and flattering skin tone reproduction even in challenging light.

Landscape Photography

Dynamic range, resolution, and environmental resilience matter most.

While both cameras share the same sensor size, the E-M5’s newer 16MP sensor and superior dynamic range (approximately +2 stops better) capture more detail in shadows and highlights, crucial for landscapes under varying light.

Additionally, the E-M5’s weather sealing lets photographers shoot in mist, drizzle, or dusty conditions - a critical feature missing from the E-300.

Wildlife and Sports Photography

High-speed autofocus, burst rate, and telephoto lens capability are key.

The E-300’s slow 3 fps burst and three-point AF struggle to maintain tracking in fast-moving wildlife or sports scenarios, and higher ISO limitations hinder low-light captures.

The E-M5’s fast 9 fps burst, 35 AF points with tracking, and high ISO ceiling provide significant advantages. Combined with the lightweight body and vast lens selection, this mirrorless system better suits demanding wildlife and sports shooters.

Street Photography

Discretion, portability, and low light performance empower street shooters.

The E-300’s larger body and louder shutter noise render it less subtle, while its limited ISO ceiling reduces low-light capability.

By contrast, the E-M5’s compact size, quieter electronic shutter options (though without a dedicated silent mode), and better high ISO noise control facilitate candid street work.

Macro Photography

Macro demands precision focusing and often stabilization for handheld close-ups.

The E-300 offers manual focusing assistance but no image stabilization, pushing reliance onto steady hands or tripods.

The OM-D E-M5’s 5-axis stabilization dramatically improves handheld macro shooting, plus the touchscreen focus peaking aids pinpoint focus accuracy.

Night and Astro Photography

High ISO performance and long exposure stability are critical.

The E-300 caps out at ISO 1600 with considerable noise intrusion, limiting astro-photography usability.

The E-M5, with an ISO ceiling of 25,600 and clean output up to ISO 1600–3200, far outperforms it. While neither camera includes built-in intervalometers, the E-M5’s live view exposure preview helps in achieving precise night exposures.

Video Capabilities

Video was not a focus for the E-300; it lacks any video recording feature.

The E-M5 introduced Full HD video at 1080p with up to 60 fps, supporting H.264 codecs. Despite no mic/headphone ports, built-in electronic stabilization and flexible autofocus modes make the E-M5 a respectable all-in-one hybrid shooter.

Technical Summary of Key Features

Real-World Testing Notes and Workflow Integration

Having put these cameras through rigorous shooting sessions - ranging from bright outdoor landscapes to candlelit interiors - some workflow considerations arise.

The E-300 RAW files (8MP, .ORF format) remain adequate for small prints and web use but lack the flexibility in post-processing granted by the E-M5’s higher resolution and dynamic range. Additionally, E-M5 files integrate seamlessly with modern Adobe CC RAW converters, with better lens correction profiles and noise reduction.

Connectivity-wise, the E-M5’s Eye-Fi card compatibility and HDMI output enable smoother tethered workflows and easier image transfer. The E-300, with USB 1.0 and no wireless options, feels dated and inconvenient for today’s rapid sharing culture.
