In this deep dive, I’ll break down each crucial facet - from sensor prowess and autofocus acuity to lens ecosystems and real-world handling - enriched with practical insights from field shoots, studio sessions, and more. Whether your priority is fast-paced wildlife, delicate macro, or video storytelling, there’s something here for you.

Size and Ergonomics: Feel the Difference

At first glance, the Olympus OM-D E-M1 presents itself as a robust, professional tool, while the Panasonic G6 leans toward a lighter, more compact enthusiast-level design. Both resemble DSLR-style mirrorless bodies, but handling them side-by-side is revealing.

The E-M1, measuring 130x94x63mm and weighing 497g, offers a substantial, confident grip that fits comfortably in larger hands. This solidity translates to a sense of durability and stability, especially valuable during long wildlife or sports shoots. Its buttons are well spaced, firm yet tactile, and thoughtfully positioned for intuitive access without contorting your fingers.

Conversely, the G6’s 122x85x71mm frame and lighter 390g weight make it ideal for travel and street photography when portability is paramount. While smaller, it doesn’t feel toy-like; the grip is adequate but less commanding than the E-M1’s. The fully articulated screen mounts to its body neatly, a savvy choice for vloggers and selfie takers.

Both incorporate tilting 3-inch LCD screens with excellent resolution - 1037k dots for the Olympus and 1036k for Panasonic - though the G6 edges ahead with full articulation versus the E-M1’s tilting only.

Top Plate Controls & Layout: Action Within Reach

Ergonomics extend beyond shape to incorporating physical controls most photographers crave - dials, buttons, and menus must feel fluent under thumb and forefinger alike.

The Olympus E-M1 boasts a pro-style commanding layout: dual control dials (front and rear), a dedicated on/off switch, direct access buttons for ISO, white balance, and focus modes. These buttons have ample travel, firm clicks, and satisfyingly precise feedback. For photographers juggling rapid setups, this arrangement cuts down fumbling.

The Panasonic G6, while a step down in control heft, smartly integrates mode dials and a single control wheel. The exposure compensation dial is placed ergonomically, and while button placement is decent, some controls require menu navigation, slowing workflow for advanced users. The G6 includes a traditional on/off dial that feels responsive.

If you prefer hands-on shooting requiring quick adjustment - sports and wildlife photographers especially - the E-M1’s design clearly leads.

Sensor Size and Image Quality: Decoding the Micro Four Thirds Magic

Both cameras use a Four Thirds sensor measuring 17.3 x 13mm, representing a crop factor of 2.0x, but subtle technological nuances influence image rendering and noise performance dramatically.

• Olympus E-M1: Employs a 16MP Live MOS sensor paired with the TruePIC VII processor. Its DxOMark score of 73 reflects strong overall performance, with a notable color depth of 23 bits and excellent dynamic range (12.7 EV). This sensor handles high-ISO noise well - usable ISO extends cleanly up to 3200, enabling night and event photography with confidence.

• Panasonic G6: Shares the 16MP sensor size and resolution but lags behind with a DxOMark overall of 61, color depth of 21.3 bits, and dynamic range of 11.5 EV. The maximum clean ISO habitually bottoms out around 1600 to 3200 depending on the scene. This affects low-light performance and subtle tonal gradation, crucial for high-contrast landscapes or shadow detail retrieval.

Image resolution is identical at 4608x3456 pixels, supporting large prints and careful cropping. Both retain the anti-alias filter, providing smoother transitions but slightly limiting ultimate sharpness compared to sensor designs without it.

For photographic genres demanding the highest tonal fidelity and dynamic range - landscape, studio portraits, and astrophotography - the Olympus’s sensor and processing edge widens appreciably.

Building for the Elements: Weather Sealing and Durability

Professionals routinely shoot in challenging environments, so sealing and build quality become decisive.

The Olympus E-M1 was designed with professional outdoor use in mind: magnesium alloy body with comprehensive weather, dust, and splash sealing. While not waterproof, the E-M1 confidently withstands light rain, dust storms, and cold winter conditions without compromising function.

The Panasonic G6 lacks any weather sealing and uses more plastic in its construction to keep weight and cost down. This inherently limits its appeal for professionals working in harsh conditions or frequent outdoor adventures.

For landscape photographers demanding reliability in foggy mornings or wildlife shooters in inclement weather, the Olympus’s robust construction justifies the investment.

Autofocus Systems Put to the Test

Autofocus prowess remains one of the most critical differentiators in mirrorless cameras, directly impacting success in portraits, wildlife, sports, and more.

• Olympus OM-D E-M1: Incorporates a hybrid autofocus system blending 81 phase-detection autofocus points with contrast detection, vastly improving speed and accuracy. Phase points are especially beneficial for tracking moving subjects, with continuous autofocus rated up to 10fps frame rate.

• Panasonic G6: Relies solely on contrast-detection autofocus with just 23 focus points. It achieves 7fps burst shooting but lacks the refined predictive tracking phase-detect autofocus delivers.

How does this translate in practice?

• Portraits: Eye detection is robust on the E-M1, nailing crisp focus on subjects’ eyes even at wide apertures to produce creamy bokeh. The G6’s autofocus is competent but less aggressive, occasionally hunting in low-contrast areas.

• Wildlife: The E-M1’s phase AF shines - fast-moving birds and mammals are tracked well with minimal focus loss. The G6 can struggle, especially under changing light or sporadic motion.

• Sports: Again, the E-M1’s advanced AF combined with faster shutter speeds and 10fps shooting gives a clear advantage.

For casual shooting and static subjects, the G6’s AF will suffice. But serious action photographers or nature enthusiasts will appreciate the Olympus’s superior AF system.

Viewfinder and LCD Screen Experience

Both cameras employ an electronic viewfinder (EVF), fundamental for composing in bright light and achieving precise focus manually.

• E-M1 EVF: 2.36M dot OLED, 0.74x magnification, 100% coverage - bright, crisp, and offering natural colors. It facilitates accurate framing and focus confirmation even in bright sun.

• G6 EVF: Lower resolution 1.44M dot OLED, slightly smaller 0.7x magnification, but similarly full coverage. It’s decent, though noticeably softer and less immersive compared to the E-M1.

Their rear 3” LCDs both feature 1037k+ resolution, but the G6’s full articulation provides versatility for video and vlogging, whereas the E-M1’s tilting screen suits still photography better.

For photographers who rely heavily on the EVF for manual focus or bright daylight shooting, the E-M1’s superior EVF quality is a definite plus.

Video Capabilities: Not Just Stills

Video is no longer an afterthought but a critical tool for many shooters.

• Olympus E-M1: Records Full HD (1080p) at 30fps max with MJPEG or H.264 codecs. It includes a mic input but no headphone jack, lacks 4K, and has in-body 5-axis image stabilization, which is a standout for video smoothness. However, the max frame rate and codec options feel limited for modern content creators.

• Panasonic G6: More progressive video options - Full HD up to 60fps allowing smoother motion capture, and it supports AVCHD and MPEG-4 codecs. It features a mic input but no headphone out. Unfortunately, no in-body stabilization is available, meaning lens stabilization or gimbal use is necessary.

For casual to intermediate video users, the G6’s higher frame rate options might be more attractive. However, those seeking steady handheld video will value Olympus’s in-body stabilization.

Lens Ecosystem and Compatibility

Both cameras utilize the Micro Four Thirds lens mount with approximately 107 lenses available - a robust ecosystem by any standard.

A key differentiator lies in the Olympus body’s tighter integration with Olympus’s professional-grade M.Zuiko Pro lenses, renowned for optical excellence and weather sealing, perfectly complementing the rugged body.

Panasonic’s G series often pairs with their Leica-branded optics, focusing on affordability and versatility but occasionally lacking the same rugged build or niche specialty lenses.

This means if you are building a high-performance kit, Olympus’s ecosystem nudges ahead in professional optic choices, while Panasonic offers a fantastic value-driven system for beginners and enthusiasts.

Battery Life and Storage Flexibility

Battery endurance can make or break extended shooting days.

• Olympus E-M1: Rated at approximately 350 shots per charge, which aligns with real-world experience - actual usage manages around 300-350 depending on camera modes and screen use.

• Panasonic G6: Slightly lower at 340 shots but very comparable.

Both utilize single SD card slots supporting SDHC/SDXC cards, imposing careful management but still adequate for most users.
