When two cameras share a brand name but hail from vastly different eras and styles, the comparison is bound to be an intriguing journey - not just through specs, but through photographic philosophies, technological leaps, and user expectations. Today, we pit the Olympus OM-D E-M5 III, a 2019 mirrorless Advanced camera powerhouse, against the vintage yet venerable Olympus Stylus 7040 (also known as the mju 7040), a compact point-and-shoot from 2010.

The goal? To provide a hands-on, detailed comparison that goes beyond marketing speak and raw specs, to help you discern which camera may deserve a place in your gear bag - or maybe just in your memory card folder.

Getting Physical: Size, Weight, and Handling

First impressions matter, and there's no better place to start than the cameras’ physicality.

The E-M5 III is robust and solid, sporting an SLR-style mirrorless body with dimensions of 125x85x50mm and weighing in at 414g without lens. Its ergonomy is purpose-built for photographers who demand control and comfort during extended shoots. Solid grip, intuitive button layout, and a heft that inspires confidence - even through long wildlife or sports sessions.

Contrast that with the Olympus Stylus 7040 - a tiny pocket rocket at 95x56x26mm and 144g. This ultra-compact design screams "grab and go" convenience, perfect for casual walkabouts or travel when lugging gear isn’t an option. It fits snugly in a jacket pocket or purse, making it a true street or travel companion for snapshots.

Handling? The E-M5 III’s larger size provides better tactile feedback and allows for sophisticated controls like customizable dials and buttons. The 7040’s fixed lens and limited controls reflect its compact point-and-shoot nature - less about control, more about speed and simplicity.

In short: E-M5 III wins for ergonomic comfort and handling versatility; Stylus 7040 triumphs for pocketability and stealth.

Design and Controls: Modern Interface vs Classic Simplicity

The camera's control scheme reveals its intended user and use cases.

The E-M5 III offers a well-thought-out interface, featuring dedicated dials for shutter speed, exposure compensation, and a mode dial. This setup, combined with the tilting touchscreen and eye-level electronic viewfinder, lets the user shoot quickly and intuitively, with manual, aperture, shutter priority modes aplenty. The TruePic VIII processor powers a responsive UI - a far cry from the sluggish menus of old.

The 7040, by contrast, offers a streamlined top plate with minimal buttons and a fixed mode setup. No manual exposure modes here - everything is handled via the fixed lens’s automatic exposure and autofocus systems. This design suits novices and travelers seeking quick operation without fuss.

Speaking of screens:

The E-M5 III features a 3-inch fully articulating touchscreen boasting a 1040k-dot resolution, great for composing at awkward angles and reviewing images with clarity. The Stylus 7040's 3-inch screen offers only 230k dots with no touch capabilities or articulation - a reflection of simpler times.

What this all means: if tactile control and customization are your bread and butter, the E-M5 III’s interface is a significant step up. Meanwhile, the 7040 keeps things honest and uncomplicated - a charm for casual, spontaneous use.

Sensor and Image Quality: The Core of the Matter

Let’s talk tech - sensor size, resolution, and resulting image quality are critical to understanding what photos you can expect.

The OM-D E-M5 III sports a Four Thirds MOS sensor measuring 17.4x13mm with 20MP resolution. That sensor size and resolution combo promises sharp, detailed images with excellent dynamic range (even though DxOMark hasn’t tested the exact scores). Importantly, the E-M5 III’s sensor includes an anti-aliasing filter and can happily push ISO up to 25,600 natively, with a low ISO of 200.

The Stylus 7040 utilizes a tiny 1/2.3” CCD sensor (6.08x4.56mm) with 14MP resolution. This sensor's physical area is less than an eighth of the E-M5 III’s, meaning much smaller photosites that struggle in low light and show more noise at higher ISOs (max ISO 1600).

In practice, this translates to sharp, vibrant images from the E-M5 III with respectable noise control even in challenging conditions - perfect for professional work, landscapes, or portraits. The 7040, while capable of decent daylight shots for casual sharing, significantly trails in image quality when scrutinized or pushed in demanding scenarios.

Real-World Shooting Across Genres

Let's dive into the nitty-gritty, exploring how these two cameras fare in key photography disciplines, from portraiture to sports, based on hands-on testing and my experience.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portraits often separate the wheat from the chaff, especially regarding color rendition and autofocus precision.

The E-M5 III really shines here. Its TruePic VIII processor works in concert with Oly’s powerful 121-point hybrid AF system (contrast + phase detection), ensuring fast, accurate eye detection autofocus - a boon for capturing expressive portraits with tack-sharp eyes and softly defocused backgrounds, thanks to the potential to pair it with fast, prime lenses on the Micro Four Thirds mount.

While the 20MP resolution enables fine detail rendition in skin texture, the sensor's Four Thirds size and lens options (consider f/1.8 primes) produce creamy bokeh that defies its smaller sensor class. The E-M5 III also supports face and eye detection, automating focus even on moving subjects.

In comparison, the 7040 has no face or eye-detection AF, relying on a contrast-detect AF system that’s slower and less reliable. Its fixed lens, ranging 28-196mm equivalent but with a variable max aperture (f/3.0-5.9), is not designed to create significant background blur, making portraits more “snapshot” than studio-esque. Skin tone reproduction is okay, but the small sensor’s JPEG processing can produce flatter colors and less pleasing tonal gradation.

Winner: E-M5 III for serious portraiture with superior autofocus and better optical options.

Landscape Photography: Dynamic Range and Durability

Landscape photography tests dynamic range, resolution, and ruggedness - areas where the E-M5 III flexes its muscles.

The 20MP Four Thirds sensor provides ample detail for large prints and cropping. Olympus’s sensor stabilisation helps exposures, and the camera supports focus bracketing and stacking - helpful for extreme depth of field control on macro or landscape shots. Weather sealing is a major win here: the E-M5 III's mag-alloy chassis is dust- and splash-resistant, letting you shoot confidently in inclement weather.

The 7040’s compact, unsealed body and tiny CCD sensor limit its suitability for serious landscapes. Dynamic range is notably compromised, especially in shadows and highlights, and image resolution is lower, which means less cropping flexibility. The fixed lens gets you decent wide angles but can't compete with interchangeable prime or ultra-wide zooms.

Landscape pros will appreciate the E-M5 III’s versatility, ruggedness, and image quality, while the Stylus 7040 is more a “convenient daylight landscapes” tool.

Wildlife and Sports Photography: Autofocus and Speed

Speed and autofocus accuracy are critical when capturing fleeting moments.

The E-M5 III boasts a 30 fps continuous shooting mode with electronic shutter, backed by its 121-point AF system with face and eye detection tracking. Its burst speed and robust autofocus tracking make it reliable for fast wildlife and sports photography, provided you pair it with telephoto lenses on the Micro Four Thirds mount. The camera's relatively lightweight helps with handheld tracking.

On the flip side, the 7040’s single shot per burst and slow shutter range (max 1/2000s) massively limit its utility for action photography. The autofocus is slower and less intelligent, unable to track moving subjects effectively.

Clearly: the E-M5 III wins hands down here for enthusiasts or pros pursuing action shots.

Street Photography: Discretion and Low Light Usability

Street shooters tend to appreciate small, discreet cameras with good low-light capability and ease of operation.

Here, the Stylus 7040 shines - it’s small, lightweight, and quiet, darting unobtrusively through crowds. Its built-in flash is simple but effective for fill light in urban shadows. That said, it struggles in low light owing to its small sensor and limited ISO range.

The E-M5 III is bigger, noisier on the street, but offers a tilting screen and excellent low-light performance (ISO up to 25600), plus silent shutter modes - a big advantage for stealth. The extensive lens mount ecosystem means you can balance size and focal length for street shooting - from pancake primes to compact zooms.

If stealth and ultimate portability trump image quality, the 7040 is a solid grab-and-go; for better quality and flexibility, the E-M5 III is the better choice - if you don't mind the size.

Macro Photography: Magnification and Precision

If detailed close-ups are your passion, precision focusing and stabilization matter.

The E-M5 III supports focus bracketing and stacking, with a potent in-body 5-axis sensor stabilization system that lets you nail tack-sharp close-ups even handheld. Compatible macro lenses and accessories unlock excellent magnification and fine control.

The 7040 offers a 2cm macro focus range with sensor-shift stabilization but no focus stacking or bracketing. It’s okay for casual macro snaps but lacks the finesse or extension options.

For anyone serious about macro, E-M5 III is the obvious choice.

Night and Astrophotography: High ISO and Exposure Control

Low light prowess is where sensor size and noise handling dominate.

Thanks to the E-M5 III’s larger Four Thirds sensor, advanced image processor, and high max ISO of 25,600, it outperforms the 7040 markedly in night shooting and astro photography. The camera also supports longer exposures (shutter speed down to 60 seconds) and has features like silent electronic shutter and timelapse recording.

The 7040 maxes out at ISO 1600, has a shutter speed max of 4 seconds - not exactly ideal for starscapes or night scenes requiring delicate long exposures.

For night owls, the E-M5 III is the persuasive winner.

Video Capabilities: Resolution, Formats, and Stabilization

While Olympus isn’t always celebrated for video, the OM-D E-M5 III offers decent options for hybrid shooters.

It shoots 4K DCI UHD (4096x2160) at 24p with high bitrates (~237 Mbps), delivering sharp detail and vibrant color. H.264 compression ensures compatibility, and a microphone port is handy for external audio. Sensor-based 5-axis stabilization assists in smooth handheld footage.

In contrast, the Stylus 7040 is limited to 720p HD video at 30fps using outdated Motion JPEG compression. No external mic input, no advanced stabilization beyond Sensor-shift, and basic video controls make it a mere snapshot companion.

Professionals and enthusiasts will appreciate E-M5 III’s video offerings; 7040 video is an afterthought.

Travel and Everyday Use: Versatility and Battery Life

Travel photography demands a balance of versatility, portability, and runtime.

The E-M5 III, while bulkier, offers interchangeable lenses, weather sealing, wireless connectivity (Wi-Fi and Bluetooth), and a respectable battery life of about 310 shots per charge. The bigger screen and EVF enhance framing versatility.

The Stylus 7040’s ultimate portability and fixed lens are wins for casual travel. However, it lacks wireless features, has no GPS, and typically fewer shots per battery charge (not specified, but typical of cameras this size).

For casual day trips and light travel, the 7040 excels. For longer or more serious journeys, the E-M5 III’s flexibility and ruggedness pay dividends.

Professional Use: Reliability, File Formats, and Workflow

Professionals require files that integrate seamlessly with workflows, dependability in challenging conditions, and precise control.

The OM-D E-M5 III shoots RAW files for detailed post-processing control - no surprise here. Its solid build, weather sealing, and expansive lens options make it an asset in any serious pro's kit. USB 2.0 connectivity is a tad behind the curve, but wireless FTP and tethering solutions for Olympus cameras fill the gap. Custom white balance, multi-segment and spot metering add to control.

The Stylus 7040 does not support RAW and uses older JPEG formats, limiting professional viability. No weather sealing or external flashes restrict creativity in professional setups.

For workflow integration and field reliability, the E-M5 III is the clear professional choice.
