Olympus E-PM1 vs Panasonic G95: An Expert Hands-On Comparison for Photographers

Selecting the right mirrorless camera demands an informed balancing of legacy versus modernity, simplicity versus sophistication, and budget versus capability. Today we pit two Micro Four Thirds contenders against each other: the venerable Olympus PEN E-PM1, a 2011 entry-level mirrorless, and the more recent 2019 Panasonic Lumix DMC-G95, a versatile advanced model. This article delivers an exhaustive, feature-driven comparison informed by over 15 years of testing experience - addressing sensor performance, autofocus, handling, video, and more - so you can determine which suits your photography ambitions and workflow best.

I. Design, Build, and Ergonomics: Compactness Versus Command

Olympus E-PM1:
Physically modest, the E-PM1 embodies the compact “rangefinder-style” mirrorless ethos prevalent in the early 2010s. Measuring 110x64x34 mm and weighing only 265 grams (body only), it is easily pocketable and appeals to users prioritizing portability. Its plastic construction and light build, while advantageous for travel and casual shooting, limit durability and weather resistance. The ergonomics echo this simplicity with minimal grip protrusion and no built-in viewfinder - viewfinder usage requiring optional external accessories. Those accustomed to DSLR-style handling may find the E-PM1 somewhat cramped and less reassuring for extended use.

Panasonic G95:
By contrast, the Panasonic G95 is a traditional DSLR-inspired mirrorless camera with a pronounced grip and robust 130x94x77 mm dimensions, weighing 536 grams. It features an SLR-style form factor with a substantial front grip and more pronounced control surfaces, fitting comfortably in larger hands and reassuring users used to heftier gear. Perhaps most importantly, the G95 incorporates environmental sealing to resist dust and splash, a feature entirely missing from the E-PM1. For photographers demanding a durable, weather-resistant body for outdoor work, the G95 asserts superiority unmistakably.

Control Layout and User Interface: Classic Versus Contemporary

The control schema defines operational flow:

• E-PM1: The E-PM1’s layout is minimalist, catering to beginners with limited dedicated buttons and reliance on menu navigation. Absence of illuminated buttons or customizable dials means diminished quick-access functionality. There is no touchscreen, and the rear screen is fixed, constraining framing flexibility. The top-panel is dominated by a mode dial and single command dial, but lacks dedicated AF point selection controls and exposure compensation button placement is less accessible.

• G95: The G95’s more extensive button array, dual command dials, and joystick controller provide immediate access to key settings such as autofocus points, drive modes, and exposure compensation, improving speed and responsiveness in dynamic shooting environments. Its fully articulated, 3” touchscreen (1240k-dot) further enhances ergonomic versatility, allowing touch AF, menu navigation, and framing from difficult angles. The built-in electronic viewfinder (EVF) with 2.36M dot resolution and near-full coverage is a decisive advantage for eye-level shooting clarity, absent on the Olympus.

Overall, the Panasonic’s control sophistication aligns with advanced users’ expectations for customization and rapid parameter adjustments in the field.

Sensor and Image Quality: Resolution, Dynamic Range, and Noise Performance

Both cameras employ sensors conforming to the Four Thirds size standard (17.3x13 mm, approx. 225 mm² sensor area), resulting in the same crop factor (~2.1x). However, sensor technology and resolution differ markedly.

• Olympus E-PM1: Features a 12-megapixel CMOS sensor augmented by the TruePic VI processor. While adequate for basic photography, the resolution ceiling (4032x3024 pixels) limits large-format print (beyond A3) and aggressive cropping potential. The sensor includes an anti-alias filter, slightly softening microdetail in pursuit of reducing moiré artifacts. Dynamic range measured at approximately 10.3 EV is modest by modern standards, and color depth (21-bit) is average. High ISO capabilities extend nominally to 12800, but image noise rises sharply above ISO 1600, restricting low-light utility.

• Panasonic G95: Upgrades to a more modern 20.3-megapixel CMOS sensor coupled with the intelligent Venus Engine processor. Notably, the G95 dispenses with an anti-alias filter, permitting crisper detail reproduction, ideal for landscape or portraiture requiring fine textural rendering. Maximum resolution climbs to 5184x3888 pixels, enabling higher print quality and crop latitude. Dynamic range performance is superior, optimizing highlight retention and shadow detail, essential for outdoor and HDR applications. ISO native range is 200-25600 expandable to 100, supported by advanced noise reduction algorithms that maintain usable quality at elevated sensitivities, expanding nighttime and indoor shooting capabilities.

For photographers prioritizing image quality and file flexibility, particularly in RAW workflow, the G95’s sensor offers an objectively more future-proof and versatile imaging base.

Autofocus Capabilities: Precision, Coverage, and Tracking

Both utilize contrast-detect autofocus systems within the Micro Four Thirds framework but with evolved capabilities:

• E-PM1: Employs a 35-point contrast-detect AF system with face detection and continuous AF modes. While competent in static or well-lit situations, it lacks dedicated phase-detection AF pixels, thus focusing can be slower and prone to "hunting" in low contrast or fast-motion scenarios. AF point selection is moderately flexible via the 35-area multi-point system, and contrast-based tracking is serviceable for casual portraits or street photography but insufficient for demanding subjects.

• G95: Advances to a 49-point contrast-detect system with enhanced algorithms enabling more accurate and faster acquisition. Face detection is augmented with eye-detection autofocus, a feature absent from the E-PM1, which reliably locks on to subject eyes during portraiture, substantially improving keeper rates. Continuous AF and tracking are optimized, even in challenging scenarios such as erratic wildlife movement or competitive sports. AF tracking works in conjunction with the camera’s higher burst rate to capture decisive moments with superior consistency.

While lacking phase-detection AF pixels (unlike some competing models), Panasonic’s software optimizations significantly elevate tracking performance, rendering the G95 markedly more suited for action and wildlife applications.

Burst Speed and Buffer Depth: Capturing the Decisive Moment

High frame rate capabilities directly influence performance for sports, wildlife, and event photography:

• E-PM1: Offers continuous shooting at up to 6 fps, which remains acceptable for casual sports and general-purpose shooting. Buffer depth is limited due to older technology and processing constraints, reducing sustained burst duration without slowdown.

• G95: Increases frame rate to 9 fps, enhancing odds of capturing peak action frames. Moreover, the buffer accommodates extended shoots with consistent write performance via UHS-II SD card compatibility. Combined with enhanced AF tracking, the G95 better satisfies the demands of fast-action professionals or enthusiast photographers.
