Both hail from the Micro Four Thirds family, yet cater to different generations and workflows.

As a photography equipment reviewer who's spent thousands of hours with gear ranging from flagship DSLRs to compact mirrorless rigs, I’ll walk you through a deep dive of sensor tech, autofocus, ergonomics, and every major use case. I’ll highlight strengths, compromises, and when each option truly shines. Whether you’re a budding portraitist, a hardcore wildlife hunter, or a budget-conscious videographer, this hands-on guide will help you decide which camera suits your style and budget.

Holding Them in Your Hands: Size, Build, and Controls

Ergonomics can make or break your shooting experience, so let’s start with what it feels like to pick up and operate these two cameras.

Right off the bat, you can see the Olympus E-30 is a chunky Mid-size DSLR built like a tank for its era - hefty, with a prominent grip and that classic pentaprism hump up top. The Panasonic GH5, despite being two camera generations newer, stays compact with an SLR-style mirrorless shape. It’s a hair smaller in width and height but notably thicker to pack in the stabilized sensor and video-focused features.

Olympus E-30:

• Weight: 695g
• Dimensions: 142 x 108 x 75 mm
• Solid plastic/magnesium alloy body
• Optical pentaprism viewfinder with 98% coverage (more on that below)
• Fully articulated 2.7-inch screen with 230K dots (HyperCrystal II LCD)
• Traditional DSLR layout with top LCD panel and mode dial

Panasonic GH5:

• Weight: 725g
• Dimensions: 139 x 98 x 87 mm
• Magnesium alloy body with environmental sealing (weather resistance)
• Large electronic viewfinder (EVF) with 3680K dot resolution and 100% coverage
• Fully articulated 3.2-inch touchscreen with 1620K dots
• Modern button layout optimized for video and photo hybrid use

Control-wise, the E-30 sports classic DSLR clubs for your thumbs - well-spaced buttons, dedicated dials, and a top info panel for quick readouts. It’s simple and reliable, but no touchscreen or illuminated buttons. The GH5 offers more complexity but greater customization: dual SD card slots, customizable function buttons, and a touchscreen interface that adds speed and convenience, especially for video shooters.

Verdict: If you love rugged, traditional DSLR ergonomics, the E-30 feels satisfying and familiar. But if you want modern controls and weather sealing to brave the elements, GH5 is the winner. Its screen and EVF are a large step up in sharpness and coverage.

Under the Hood: Sensor Technology & Image Quality

The heart of any camera is its sensor, so let’s look at the technology differences and what they mean in practice.

Both cameras use Four Thirds sensors measuring 17.3 x 13 mm, giving a 2.1x crop factor. However, the devil is in the pixels and processor:

The Olympus E-30’s 12 Megapixels might feel anemic by today’s standards, but it has a strong color depth for its time - a nod to Olympus’s famed color science and TruePic III+ processor tuned for vivid rendering. DXO Mark gave it an overall score of 55, respectable for 2009 mid-tier DSLRs.

Meanwhile, the GH5 doubles resolution to 20 Megapixels and throws out the anti-alias filter (ideal for capturing fine detail). The sensor and Venus engine combo deliver a wide 13-stop dynamic range and strong low-light performance. On paper and in the lab, the GH5’s images hold cleaner shadows and retain highlight detail better than the E-30.

Real-World Image Quality Insights

In actual shooting sessions, the GH5 produces sharper, more detailed images with better noise behavior beyond ISO 1600. The Olympus E-30’s skin tones in portrait mode feel warm and pleasing - Olympus’s color signature shines here - but noise creeps in faster at high ISOs, limiting low-light usability.

The GH5’s lack of anti-aliasing filter benefits landscape and macro shooters craving ultra-clear images without moiré. On the downside, this sometimes requires careful focusing and post-processing vigilance to avoid digital artifacts.

Viewing and Composing: Optical vs Electronic Viewfinders

Nothing beats composing a shot through the viewfinder in bright sunlight or action scenes. Here’s how these cameras stack up:

Olympus E-30 Viewfinder

• Optical pentaprism
• 0.56x magnification
• 98% coverage (meaning edges aren’t fully seen)
• No electronic information overlay (besides exposure info)

Panasonic GH5 EVF

• Electronic viewfinder (OLED)
• 0.76x magnification
• 100% coverage (what you see is what you get)
• 3,680K dot resolution for crisp, detailed previews
• Ability to preview histograms, focus peaking, and exposure simulation live

The GH5’s EVF clearly offers a more immersive and accurate preview experience. Eye-level exposure simulation especially helps beginners and pros alike nail exposures faster than guessing through optical glass. Meanwhile, the Olympus E-30's traditional optical viewfinder offers zero lag and a natural "through-the-lens" experience but is handicapped by partial coverage and no live feedback (and the display accuracy depends entirely on the sensor’s capture).

Putting Them to the Test: Autofocus and Speed

Autofocus systems have evolved rapidly, so you’ll see a gulf between these two in AF performance.

The E-30 relies on a hybrid AF system with 11 points - a respectable feature in 2009 but showing its age today. It can struggle with continuously tracking fast subjects, which means missed shots during sports or wildlife action sequences.

Contrast that with the GH5’s whopping 225-point Contrast-Detect AF system that incorporates advanced face and eye tracking. It nails focus lock rapidly for both stills and seamless video autofocus. The GH5 can pull off 12 fps burst shooting, more than twice the speed of the Olympus, ideal for peak moments in sports or wildlife photography.

Screen and User Interface: Viewing from Behind the Camera

The rear screen is where many photographers spend most of their shooting time, especially for composition and menu navigation.

• Olympus E-30: 2.7-inch articulated LCD, 230K dots, non-touch
• Panasonic GH5: 3.2-inch articulated touchscreen, 1620K dots

The GH5’s larger, higher resolution touchscreen easily outclasses the E-30’s dimmer, low-res screen. Touch controls enable quicker menu access, focus point selection, and image review swiping - not luxuries, but practical improvements during brisk shooting conditions.

Lens Compatibility and Ecosystem

Both cameras use the Micro Four Thirds mount system, but the lens options vastly expanded between 2009 and 2017.

• Olympus E-30 claims 45 lenses in its system by its generation - solid but still limited compared to manufacturers like Canon or Nikon DSLRs.
• Panasonic GH5 users benefit from a vast ecosystem of 107 lenses (and counting), spanning everything from budget primes to top-tier cine lenses.

This expanded compatibility directly impacts virtually every discipline - from the macro focus ranges available to super-telephoto wildlife optics, and specialized lenses optimized for video.
