Olympus E-PM1 vs Panasonic FX75: An In-Depth Camera Showdown from My Lab to Your Lens

Comparing cameras is rarely straightforward, especially when crossing genres–an entry-level mirrorless versus a small sensor compact. When the Olympus PEN E-PM1 and Panasonic Lumix FX75 hit the bench, I knew this wouldn’t just be about specs. It’d be a story about design philosophies, imaging performance, real-world usability, and who these cameras were really built for. After years pounding the shutter across varied photographic terrains - from serene landscapes to restless sports fields - I’m here to unpack how these two stack up in 2024’s photography world.

Grab your favorite lens (or pocket it) as we embark on a journey dissecting sensor tech, ergonomics, and everything in between - to help you figure out which one deserves that prime spot in your camera bag.

Getting to Know the Players: Body, Build, and Controls

The Olympus E-PM1 arrived in late 2011, riding the wave of the Micro Four Thirds mirrorless revolution. Meanwhile, the Panasonic FX75, debuting a bit earlier in 2010, represents classic small sensor compacts designed for casual shooters craving a fun pocket camera.

Starting with physical presence - a realm where first impressions stick - I laid them side by side:

The E-PM1’s rangefinder style body measures 110 x 64 x 34 mm and weighs 265g. It boasts a comfortable, if somewhat minimalist, grip that’s firm but not bulky - ideal for extended shoots without fatigue. The FX75, by contrast, is a dinky powerhouse at 103 x 55 x 23 mm and just 165g, perfect for stashing invisibly in a pocket, yet small enough to challenge handling in burst-photography scenarios (more on that later).

The E-PM1’s design leans into well-thought-out ergonomics for an entry-level mirrorless: buttons are sensibly placed and provide decent tactile feedback (never underestimate this in real shooting situations). The FX75 leans on simplicity here, with fewer control dials and buttons - probably to maximize compactness. It's approachable but sacrifices some manual control finesse, which some enthusiasts might miss.

Here’s a look at the top controls:

Olympus’s top plate wears a mode dial, shutter button with on/off collar, and a small info display - pleasantly traditional for a mirrorless. Panasonic keeps it sleek with minimal hardware, relying more on menu navigation and touch inputs (which the FX75 supports, surprisingly).

In essence, for those who cherish manual tweaking or plan long shooting sessions, the E-PM1 body layout aids concentration. Compact camera lovers wanting simple snap-and-go will gravitate toward the FX75’s design.

Face-Off: Sensor Technology and Image Quality

Here’s where the battlefield widens. Sensor size and type deeply influence image quality, noise handling, and depth of field - the stuff that defines photo look and feel.

Olympus E-PM1 sports a Four Thirds sensor (17.3 x 13 mm), a relatively large sensor for a system camera priced for beginners. This CMOS sensor packs 12 megapixels - a sweet spot for clean images, manageable files, and decent resolution for prints or cropping.

Panasonic FX75, however, houses a 1/2.3-inch CCD sensor, tiny at 6.08 x 4.56 mm, with 14 megapixels packed in. CCDs historically produce nice colors but can struggle in low light and dynamic range.

In my hands-on evaluation under controlled lighting and real-world conditions, the Olympus pulled ahead in crucial ways:

• Dynamic Range: The E-PM1 delivers roughly 10.3 EV stops (measured via DxOMark), allowing for nuanced detail in shadows and highlights. The FX75 lags (DxOMark untested officially but sensor class estimates hover near 5–6 EV), so highlights clipped sooner, and shadows tended to muddy.
• Color Depth: Olympus’s 21-bit color depth yields vibrant but true-to-life tones - skin tones rendered naturally with subtle gradations. The FX75, with an untested color profile, showed decent saturation but sometimes flatter hues color-wise.
• ISO Performance: Olympus shines up to ISO 1600 with usable noise, extending to 3200 or 6400 if you’re brave in RAW. The FX75’s tiny sensor and older CCD tech introduce noticeable noise above ISO 400, limiting low-light use.
• Resolution vs Pixel Size: While FX75 touts 14 MP, its pixel size is tinier - resulting in more noise per pixel. Olympus’s 12 MP strikes a practical balance with larger pixels capturing more photons.

Here’s a practical take: For portraits or landscapes requiring detail and compositional flexibility, the Olympus sensor enables cleaner results and better image editing latitude. The FX75 offers respectable day-lit snaps, but low-light and high dynamic range scenarios aren’t its strong suit.

The Viewfinder and Screen Experience: Seeing Your World

Digital cameras are as much about how you see as what you capture.

Neither camera offers built-in electronic viewfinders - an unfortunate gap for traditionalists. Olympus users can add an optional EVF, but I found this less convenient than having it integrated.

The E-PM1 sports a 3-inch fixed HyperCrystal LCD boasting 460k dots with an anti-reflective coating. In bright daylight, it provides sharper previews and more accurate color alerts. Meanwhile, the FX75’s 2.7-inch touchscreen LCD with 230k dots (lower resolution) felt more sluggish and less crisp, though the touch interface adds intuitive focus point selection - a plus for casual photography.

In practice, the E-PM1's screen clarity and color fidelity support critical composition and focus decisions, vital for portrait photographers or precise macro work.

Autofocus, Burst Shooting, and Manual Controls: Precision Under Pressure

The Olympus’s TruePic VI processor wields a 35-point contrast-detection AF system that supports face detection and continuous AF tracking - a boon for sports or wildlife shooters learning their craft.

By contrast, the FX75’s autofocus relies on contrast detection without face or eye detection, and lacks selectable AF points - a significant drawback for subjects on the move or selective focusing.

Burst rates highlight their real-world shooting intent:

Camera	Burst Speed	AF Mode
Olympus E-PM1	6.0 fps	Single, continuous, tracking
Panasonic FX75	2.0 fps	Single, continuous (limited)

The E-PM1 feels more sprightly capturing moments with moving kids or animals, while the FX75 is more of a casual point-and-shoot, best reserved for still images without frantic action.

Manual exposure modes on the Olympus give creative control - shutter priority, aperture priority, and full manual - while the Panasonic lacks manual exposure modes completely. Exposure compensation is available in Olympus but absent on FX75.

For photographers craving versatility and creative input, Olympus easily wins hands down here.

Shooting Across Genres: Which Camera Excels Where?

Portrait Photography

Portraits demand accurate skin tone reproduction, smooth bokeh, and reliable eye detection.

Olympus’s larger sensor and Micro Four Thirds lens ecosystem (over 100 lenses) empower shallow depth of field effects and gentle subject isolation. Its face and eye-detection autofocus enable sharp focus on eyes - a game changer for portrait clarity.

The FX75’s small sensor yields broader depth of field naturally, making background separation tricky; its lack of face detection can result in missed focus on the subject’s eyes.

Verdict: Olympus is the reliable portrait pro in this duo.

Landscape Photography

Dynamic range, resolution, and weather durability come into play here.

The E-PM1’s superior sensor captures impressive DR, making highlight recovery easier, while its 12 MP resolution is sufficient for large prints.

Neither is weather sealed, but the Micro Four Thirds mount allows Olympus users to choose weather-resistant lenses, enhancing durability.

The FX75’s limited DR and lower resolution, plus no weather sealing, steer it away from serious landscape work.

Wildlife Photography

Fast, accurate AF and burst shooting are essentials.

The Olympus’s 6 fps continuous shooting and AF tracking suit wildlife beginners working with telephoto primes. The 2x crop factor essentially doubles lens reach, beneficial in the field.

The FX75 lacks speed, AF flexibility, and reach (its zoom tops at 120 mm equivalent), limiting its wildlife potential.

Sports Photography

Again, AF speed, burst rate, and low light sensitivity matter.

Olympus’s 6 fps and tracking AF make it a reasonable starter sports camera - though not professional level, it’s forgiving for amateurs.

The FX75’s 2 fps and slower AF leave it behind the pack for capturing fast-moving action.

Street Photography

Discretion, portability, and low light success are key here.

The FX75’s pocketability and touchscreen appeal to street photographers favoring stealth. However, its poor low-light performance and small screen hinder spontaneous shooting in dim locales.

Olympus is larger but still reasonably compact and offers superior image quality and low-light prowess.

Macro Photography

Magnification capability, focusing precision, and stabilization help capture tiny details.

While the FX75 can focus as close as 3 cm, the Olympus supports macro lenses and sensor-based image stabilization (5-axis gyro in later models, though basic sensor-shift on E-PM1).

If you want sharp, well-lit macro shots, Olympus’s system is more adaptable and precise.

Night and Astro Photography

High ISO performance and exposure modes matter keenly.

Olympus’s sensor handles up to ISO 1600 cleanly (occasionally 3200 with noise reduction), and manual exposure modes aid night shots.

The FX75’s noise increases dramatically above ISO 400, limiting its astrophotography potential.

Video Capabilities

Olympus leads with 1080p at 60 fps video, plus AVCHD format for quality compression.

Panasonic, known for video, only delivers up to 720p at 30 fps, restricting smooth, high-res motion capture.

Neither has mic or headphone ports, nor advanced stabilization for video - but Olympus’s 1080p at 60 fps is more future-proof.

Travel Photography

Versatility, battery life, and size matter here.

The FX75 is ultra-light and pocket-friendly - a boon for travelers not wanting extra bulk.

Olympus is heavier but packs more punch - especially for those wanting manual control and better image quality.

Battery-wise, Olympus’s advertised 330 shots per charge is respectable; FX75’s figures are unlisted but small cameras generally sacrifice endurance.

Professional Work

Pros demand reliability, raw support, and workflow integration.

Olympus supports raw capture and integrates well with standard software pipelines.

FX75 doesn’t support RAW - disqualifying it for pro workflows that rely on maximum image flexibility.

Construction Quality and Weather Sealing

Both cameras lack environmental sealing - no dustproofing or waterproofing - so neither are suited for extreme conditions. Build quality for Olympus is solid given its target market, while the FX75 follows typical compact plastic construction.

Lens Ecosystem and Compatibility

Olympus leverages the Micro Four Thirds lens mount, giving access to over 100 lenses - primes, zooms, fast apertures, and specialty lenses - excellent for enthusiasts expanding their craft.

Panasonic FX75 has a fixed 24-120mm equivalent zoom lens onboard - convenient but limiting optical diversity.

Battery and Storage

Olympus’s BLS-5 battery delivers around 330 shots - a respectable endurance.

FX75’s battery model is unspecified; judging by size, expect moderate lifetime needing spare batteries for extended outings.

Both use single SD/SDHC/SDXC cards.

Connectivity and Wireless Features

Neither offers Bluetooth, Wi-Fi, or GPS, so tethered use or post-shoot transfers via card readers are standard. Olympus does include HDMI and USB 2.0 (same as FX75).

Pricing and Value Assessment

At launch, Olympus E-PM1 priced around $499; FX75 notably cheaper at $139, reflecting their targeted users and tech specs.

What you’re buying with E-PM1 is a capable mirrorless system with room to grow.

FX75 is a casual camera for spontaneous use and convenience.
