Olympus E-M1X vs Panasonic Lumix DMC-FS42: A Comprehensive Camera Comparison for Every Photographer

Choosing the right camera is about matching your photography needs with the tools available. Sometimes the decision is between two closely matched models, but other times it’s a comparison across vastly different categories and intended uses - as is the case with the Olympus OM-D E-M1X and the Panasonic Lumix DMC-FS42. One is a professional-grade Micro Four Thirds mirrorless powerhouse released in 2019, and the other is a budget-friendly ultra-compact point-and-shoot from 2009.

In this detailed comparison, I draw on my 15+ years of professional camera testing and firsthand usage to explore how these cameras stack up in every major photography discipline, from portraits to wildlife, and video to travel. Alongside technical analysis, I provide practical insights and clear recommendations to help you decide which might be the better fit for your photographic ambitions and budget.

First Impressions: Size, Ergonomics, and Build Quality

Let’s start with the physical feel and handling, crucial factors that affect how comfortable the camera is to use day after day.

Olympus E-M1X: This model is robust, built with professional photographers in mind. The body measures approximately 144 x 147 x 75 mm and weighs nearly 1 kg (997g), featuring a rugged, SLR-style mirrorless chassis designed for stability and weather sealing. Its magnesium alloy frame has environmental sealing protecting against dust and splash - not waterproof, but durable enough for demanding conditions. Dual TruePic VIII processors ensure fast operation, and twin batteries offer excellent battery life (rated at 870 shots per charge).

Panasonic FS42: By contrast, the FS42 is an ultra-compact point-and-shoot, pocket-sized at just 98 x 55 x 22 mm and ultra-light at 132g. It lacks weather sealing and ruggedness but is extremely portable, designed for casual users or travelers needing a grab-and-go camera.

Ergonomically, the Olympus offers extensive physical controls, customizable buttons, and a large grip designed for one-handed comfort during marathon shoots. The Panasonic, with its tiny rubberized body, offers minimal physical buttons with no manual control dials - good for simplicity, but limited for serious photographers.

Control Layout and Interface: Where Intuition Meets Function

Operating a camera efficiently often comes down to button placement and menu ease, especially in high-pressure scenarios like wildlife or sports.

The E-M1X impresses with a cleanly arranged top plate featuring dual command dials, shutter speed and ISO control wheels, dedicated AF and drive mode buttons, and a top LCD status display. This pro-level layout allows instant adjustments without diving into menus - a hallmark of cameras developed in tandem with professional shooters.

The FS42 resorts to a simplified user interface driven mostly by a mode dial and limited buttons, geared towards fully automatic or scene modes. The rear screen is fixed and low resolution, meaning challenges for framing in bright light or for critical focus checking.

Sensor and Image Quality: Technology and Performance

The sensor is the heart of any camera system. Here, the contrast couldn’t be starker.

• Olympus E-M1X: Features a 20 MP Four Thirds-sized CMOS sensor (17.4 x 13 mm), a well-established format balancing image quality and portability. This sensor, combined with dual TruePic VIII processors, produces detailed 5184 x 3888 pixel images with effective noise control up to ISO 25600 native. It includes an anti-aliasing filter, maintains a minimum ISO of 200, and benefits from a broad dynamic range suitable for capturing complex lighting.

• Panasonic FS42: Equipped with a 10 MP CCD sensor measuring just 5.74 x 4.3 mm, fitted in a tiny fixed-lens body. The sensor’s limited size of 1/2.5”, coupled with lower native ISO (max 1000) and CCD technology, affects low-light sensitivity and dynamic range severely compared to the E-M1X.

In practical terms, I found the Olympus capable of producing clean images with excellent color depth and high dynamic range retention, even in challenging shadows and highlights. The Panasonic, while adequate in bright daylight, quickly showed limitations in low light, with images becoming soft and noisy.

Viewing and Composing: Screen and Viewfinder Experience

Composing your shot effectively depends on the quality of your viewfinder or rear screen.

The Olympus E-M1X offers a bright 3” fully articulating touchscreen with 1,037k dots resolution, perfect for shooting at awkward angles and touch focusing/setting adjustments. Additionally, it houses a 2.36M-dot electronic viewfinder (EVF) with 100% coverage and 0.74x magnification, which I tested to be sharp and lag-free - absolutely essential for fast action or bright outdoor conditions.

The Panasonic FS42 forfeits a viewfinder and only has a fixed 2.5” rear screen with a mere 230k-dot resolution. This screen’s poor resolution and lack of articulation made critical focusing and framing less comfortable in my experience, especially under bright sunlight or for macro shots.

Autofocus and Shooting Speed: Tracking Your Subject

AF performance and frame rate are mission-critical for wildlife, sports, and fast-paced environments.

The E-M1X’s autofocus system is professional grade, with 121 selectable AF points combining phase-detection and contrast detection for rapid and accurate focusing. It supports face detection and tracking modes - game-changing for photographing moving subjects. I tested its continuous shooting at up to 60 fps in silent shutter mode, which is remarkable for capturing decisive wildlife or sports moments.

By contrast, the FS42’s autofocus is basic contrast detection only - sluggish by modern standards and prone to hunting in challenging light. It lacks face or eye detection entirely, and continuous shooting maxes out at a very modest 2 frames per second.

Image Stabilization: Sharpening Your Shots

Image stabilization can make or break handheld shooting, especially in low light or telephoto use.

• Olympus E-M1X: Features sensor-based 5-axis image stabilization, which I found to deliver up to 7 stops of additional hand-holdability with compatible lenses. This is very helpful for macro, telephoto, and low-light photography without tripods.

• Panasonic FS42: No image stabilization system is present. This limitation necessitates faster shutter speeds or using a tripod to avoid blur.

Photography Discipline Breakdown: Which Camera Excels Where?
