Choosing the right camera is a pivotal step in any photographer’s creative journey. Whether you’re capturing portraits, chasing wildlife, or crafting cinematic videos, your camera is your tool and partner. Today, we explore two advanced DSLRs from different generations and systems: the Canon EOS 90D, announced in 2019, and the Olympus E-30, launched back in 2009. While both fall under the "advanced DSLR" category and share ergonomic similarities, they belong to very different tech eras and sensor formats, which profoundly impacts their capabilities.

With over 15 years of firsthand camera testing experience, I’ll take you through every critical aspect - from sensor tech to autofocus, from real-world shooting scenarios to value assessments - to help you understand which of these could fit your photography style and goals.

First Impressions: Size, Controls, and Handling

Handling and ergonomics are the foundation of a good camera experience. Let’s begin by comparing the physical footprint and control layout.

Size and Ergonomics

The Canon 90D and Olympus E-30 are both mid-size DSLRs designed for enthusiast photographers. The 90D measures approximately 141 × 105 × 77 mm and weighs around 701 grams. The Olympus E-30 is slightly deeper at 142 × 108 × 75 mm and weighs marginally less at 695 grams. Despite the size proximity, differences in grip design and button layout affect comfort and ease of use.

You’ll notice the Canon’s grip is slightly more pronounced, designed for extended shooting sessions, especially with larger telephoto lenses. The Olympus, meanwhile, has a somewhat more compact feel, aligned with its Micro Four Thirds system benefits.

Top View Controls

Let’s peek at the top plate controls where many photographers adjust critical settings on the fly.

Canon’s EOS 90D features a modern control layout with a dedicated mode dial, secondary control dial, and accessible ISO/shutter speed buttons. The Olympus E-30’s setup is simpler, with fewer dedicated buttons but still includes a comprehensive set of dials for PASM modes.

In practice, the Canon’s controls offer more customization and tactile feedback for rapid adjustments - a boon during dynamic shoots such as sports or wildlife.

Sensor Technology & Image Quality: The Heart of the Camera

The sensor underpins your image’s resolution, dynamic range, noise performance, and color reproduction. Here, the cameras diverge sharply.

Sensor Size & Resolution

The Canon’s larger APS-C sensor physically captures more light and supports a much higher resolution - 33 MP versus 12 MP on the Olympus. This translates to more detail and better cropping flexibility for large prints or intense post-processing.

Image Quality and Noise Performance

In controlled laboratory tests and real-world shooting, the 90D exhibits excellent tonal range and color accuracy, benefitting from Canon’s Digic 8 processor enhancing noise reduction without losing detail. ISO performance extends natively up to 25600 with expansion to 51200, delivering usable images in low light.

The Olympus lags behind here. Its 12 MP Four Thirds sensor exhibits more noticeable noise beyond ISO 800-1600. While Olympus’ sensor-based image stabilization helps in certain scenarios, intrinsic noise reduction performance can’t fully compensate.

Autofocus Systems Compared: Accuracy Meets Speed

Autofocus (AF) performance can make or break your shooting experience, especially with moving subjects.

Canon’s 45 cross-type autofocus points deliver reliable performance across the frame, with advanced tracking and face detection helping track subjects smoothly - ideal for wildlife, sports, and street photography. The touchscreen AF with touch-to-focus enhances usability in live view, important for macros or video.

Olympus’s 11-point AF system is more limited, lacking effective continuous tracking and face/eye detection. Its contrast-detection AF is generally slower, especially in low light or fast-action scenarios.

The Viewfinders and Displays: How You See Your Image

A good viewfinder and rear display are essential for composing and reviewing images comfortably.

The Canon’s 3-inch fully articulating touchscreen is considerably sharper, providing easier live view focusing and menu navigation. Olympus’s smaller, lower-res HyperCrystal II LCD is serviceable but feels dated, impeding touch interaction.

Both cameras feature optical pentaprism viewfinders suited for DSLR shooters, but Canon’s 100% coverage is advantageous for precise framing.

Battery Life & Storage: Freedom to Shoot Longer

With any camera, battery capacity and storage options impact how long you can stay in the field.

Canon's more efficient battery combined with a larger capacity means you can shoot nearly twice as many images per charge compared to Olympus. Additionally, SD card support with UHS-II makes transferring large 4K video and high-res RAW files quicker and more convenient than the older CompactFlash and xD format on the E-30.

Connectivity & Video Capabilities

Let’s not forget image sharing and multimedia capabilities in a world increasingly driven by digital workflow.
