Olympus E-520 vs Olympus Stylus 1: A Hands-On Expert Comparison for Enthusiasts and Pros

Choosing your next camera is a personal and practical decision that depends on what you shoot, your budget, and how much gear you want to carry. Olympus’s E-520 and Stylus 1 represent very different takes on photography from the same brand - one a classic entry-level DSLR from 2008 and the other a versatile bridge-style superzoom launched in 2013. Although both carry the Olympus badge, their target users, sensor sizes, controls, and feature sets couldn’t be more distinct.

I’ve tested both extensively over years of shooting across genres - from portraits and landscapes to fast-action and low-light scenarios - and in this deep-dive comparison I’ll share everything I’ve learned. Whether you’re a photographer who values image quality, portability, autofocus performance, or video capabilities, I’ll unpack the real-world strengths and trade-offs while referencing rigorous lab benchmarks, hands-on field testing, and thoughtful usage scenarios.

Let’s start by exploring their physical builds and handling, then delve into core imaging technologies, autofocus systems, usability, and performance across photography disciplines. I’ll close with clear recommendations tailored by type of photographer and budget considerations.

Size and Ergonomics: Handling a Classic DSLR vs a Bridge Zoom

At first glance, the Olympus E-520 and Stylus 1 tell two very different stories in terms of size and feel. The E-520, a compact entry-level DSLR housing a Four Thirds sensor, is noticeably chunkier and heavier at 552g. Its body measures 136x92x68mm, sporting a traditional SLR silhouette with a pentamirror optical viewfinder and deep grip.

In contrast, the Stylus 1 weighs just 402g and is smaller at 116x87x57mm. Its design mimics an SLR but is a bridge-style model with an integrated 28-300mm F2.8 fixed lens, making it extremely travel and street-friendly.

I found that the E-520’s robust DSLR-style body offers excellent stability for one-handed shooting and lens changes, with physical dials and buttons well spaced for confident control. The grip shape is comfortable for my mid-sized hands, though smaller hands might find it a bit bulky for all-day carry.

The Stylus 1’s lighter weight and smaller footprint make it a natural choice for grab-and-go and casual outings. Handling is nimble, and the tilting LCD screen (more on that later) adds framing flexibility. However, the fixed lens means you trade off the ability to swap glass for convenience.

Ergonomically, the E-520 leans into a more traditional DSLR experience with full manual control access, while the Stylus 1 blends DSLR styling with bridge camera compactness and zoom versatility.

Top Controls and Interface: Precision vs Convenience

Looking at the top plate design, the E-520 has dedicated buttons, a mode dial, and a classic shutter release layout that feels familiar to anyone who’s used DSLRs around that era. The interface invites speedy access to aperture priority, shutter priority, and manual modes - critical for creative shooting.

The Stylus 1, meanwhile, embraces a stripped-back approach, packing in a mode dial, exposure compensation dial, and a joystick-like control stick. This design reflects its hybrid stance - part enthusiast camera, part point-and-shoot convenience.

In practice, I appreciated the tactile feedback and clear labeling on the E-520’s controls, which makes diving into manual exposure quick and natural. Although the Stylus 1’s controls do the job well, I occasionally missed having physical direct access to settings like ISO, which are buried deeper in the menu system.

Both cameras include customizable buttons and exposure compensation, but the E-520’s slightly larger body aids handling of these controls without “button jamming” fingers.

Sensor and Image Quality: Four Thirds DSLR vs 1/1.7” BSI CMOS

Here lies one of the most fundamental technical differences: the E-520 employs a 10MP Four Thirds sized sensor measuring 17.3x13mm, whereas the Stylus 1 features a smaller 12MP 1/1.7” BSI CMOS sensor sized 7.44x5.58mm. This size gap significantly impacts image quality and usable ISO range.

The Four Thirds sensor in the E-520 delivers larger photosites, resulting in superior dynamic range (10.4 EV vs 11.6 EV for Stylus 1, per DxOMark), better color depth (21.4 bits vs 20.7 bits), and stronger low-light sensitivity (base ISO 100 to max 1600 native) compared to the much smaller sensor found in the Stylus 1, whose max ISO extends up to 12800 but with more noise.

In practical shooting tests, the E-520 images have richer tonality, deeper shadows, and less noise at ISO 800 and 1600. The Stylus 1 manages surprisingly clean images at base ISO but struggles with noise at anything beyond ISO 800, especially in shadows.

One tradeoff with the Stylus 1 is its focal length multiplier of 4.8x, which, combined with the long 28-300mm zoom lens (equivalent), helps get close to distant subjects but sacrifices aperture size at longer focal lengths, affecting shallow depth of field and bokeh capability.

Rear Display and Viewfinder: Optical Precision vs Electronic Flexibility

The E-520 sports a 2.7-inch fixed LCD screen with a modest 230K pixel resolution, reflective of its 2008 vintage. Its strength lies in its optical pentamirror viewfinder (95% coverage, 0.46x magnification), which offers real-time, lag-free composition ideal for quick, bright-light shooting.

The Stylus 1 upgrades with a 3-inch high-res 1040K pixel tilting touchscreen that greatly aids creative angles, live view autofocusing, and intuitive menu navigation - even though, disappointingly, it’s not selfie-focused.

The electronic viewfinder on the Stylus 1 is a 1440K pixel OLED offering 100% frame coverage and a bright, color-accurate preview, a huge improvement over the E-520's optical option for previewing exposure changes and framing in low light.

While purists might prefer the E-520’s optical viewfinder, I found the Stylus 1’s EVF excellent for seeing exposure and focusing details in real time, a major plus when working in variable lighting or shooting video.

Autofocus Systems: From Basic 3-Point to Advanced 25-Point

The Olympus E-520 adopts a fairly basic autofocus system - 3 phase-detection points with live view contrast detection, facial recognition but no eye or animal detection, and no tracking. In my hands, this system is adequate for stationary subjects and portraits but lagged behind when shooting moving objects.

The Stylus 1’s hybrid autofocus blends 25 contrast-detection points with center-weighted PDAF for live view, and includes face detection plus AF tracking. It hits 7fps continuous shooting, nearly double the E-520’s 4fps.

In wildlife and sports scenarios, I found the Stylus 1 better equipped to nail focus on unpredictable moving subjects, although not quite at mirrorless flagship speed. The E-520 is more suited for controlled environments.

Image Stabilization: Sensor-Based vs Optical Lens Stabilization

Both cameras feature image stabilization (IS), but with different approaches. The E-520’s sensor-shift IS corrects at the sensor level and performs well at moderate shutter speeds and focal lengths - excellent for handheld portraits and landscapes.

The Stylus 1 uses optical stabilization integrated into its zoom lens, which is more effective across the very wide focal range and longer telephotos (up to 300mm equivalence), reducing blur from camera shake noticeably in telephoto shots.

I tested both systems handheld at slow shutter speeds and found the Stylus 1’s optical IS more forgiving, especially when zoomed in for wildlife or travel photography.

Build Quality and Weather Resistance: Basic Compact Bodies

Neither the E-520 nor the Stylus 1 offer weather sealing, dustproofing, or freezeproof construction. Both are well-built but positioned for enthusiasts who shoot mostly indoors or in fair weather.

The E-520’s DSLR shell feels solid with metal chassis parts, whereas the Stylus 1’s plastic composite bridge body keeps weight minimal. Neither inspire confidence for heavy professional or adventure use.

Lens Options: Interchangeable Glass vs Fixed Zoom Convenience

The Olympus E-520 sits within the Four Thirds mount system, compatible with over 45 lenses ranging from primes to telephotos. This flexibility is a huge asset for photographers who want to customize gear for portraits, macro, wildlife, or wide angles.

The Stylus 1 has a fixed 28-300mm equivalent zoom lens with a bright constant aperture of F2.8. While it lacks lens-swapping freedom, this lens covers most daily scenarios with respectable optical quality and macro capability down to 5 cm, making it an excellent all-in-one solution.

If you want better image quality and versatility, the E-520 with quality Four Thirds lenses will win; for pick-up-and-go versatility, Stylus 1 shines.

Battery Life and Storage: DSLR Endurance vs Compact Convenience

The E-520’s CIPA-rated battery life reaches approximately 650 shots per charge, impressive thanks to its less power-hungry sensor and simpler LCD.

The Stylus 1 has around 410 shots per charge - a reasonable number for a compact bridge camera with a bright, high-res EVF and touchscreen.

Storage-wise, the E-520 accepts CompactFlash and xD cards, still supported but somewhat legacy today. The Stylus 1 uses ubiquitous SD/SDHC/SDXC cards, more convenient and cost-effective.

Connectivity and Extras: Limited Wireless on Both

Neither camera offers Bluetooth or NFC, though the Stylus 1 has built-in wireless for basic connectivity via Olympus’s older apps - still somewhat clunky and limited.

The Stylus 1 includes HDMI output for external monitors, beneficial for video or tethered shooting, while the E-520 lacks this port entirely.

Microphone and headphone ports are absent on both, reflecting their pre-4K and casual video era status.

Video Capabilities: From No Video to Full HD

The E-520, designed in 2008, does not support video recording.

The Stylus 1 records Full HD 1080p at 30fps, plus lower resolutions at higher frame rates (480p at 120fps), useful for slow-motion effects. Video quality is respectable for a bridge camera, with smooth autofocus and optical stabilization helping handheld clips.

For anyone wanting video, the Stylus 1 clearly offers superior flexibility.
