Olympus E-520 vs. Olympus Stylus SP-820UZ: A Hands-On Comparison for Photography Enthusiasts

When it comes to choosing a camera, especially with Olympus offering such different models in its lineup, it’s easy to feel overwhelmed. I’ve spent countless hours testing and comparing entry-level DSLRs against small sensor superzoom cameras, and today we’re digging deep into two Olympus offerings from different corners of the market: the Olympus E-520 and the Olympus Stylus SP-820UZ. They cater to distinct shooters with unique priorities, so let me break down their strengths and weaknesses based on real-world performance and technical specs I’ve personally vetted over years in the field.

Before we dive into nuanced use cases, ergonomics, and image quality, here’s a quick heads-up: both cameras are budget-friendly choices, but they serve very different photographic personalities and shooting styles. With that in mind, let’s get started.

Getting Acquainted: Size, Build, and Handling

First impressions matter, especially when you’re holding a piece of gear for hours on end during shoots. The Olympus E-520 is a classic entry-level DSLR, while the Stylus SP-820UZ is a compact superzoom bridge camera. Let me visually and tactilely break down what sets them apart ergonomically.

The E-520 boasts a traditional DSLR form factor measuring 136 x 92 x 68 mm and weighing 552 grams. It has a firm, somewhat compact grip that caters to enthusiasts who appreciate clubbing their thumbs onto rubberized grips rather than holding a bare slab.

The SP-820UZ is smaller and chunkier at 117 x 78 x 93 mm and just 485 grams. Its bridge camera styling means a fixed lens houses that massive 40x zoom, so it’s bulkier from front to back but easier to toss in a bag for travel or street photography. Because of this, it feels somewhat less sturdy but is easy to manage one-handed thanks to the deep, rounded grip.

While testing, I found the E-520’s heft and control layout superior for longer sessions especially when using interchangeable lenses. The SP-820UZ’s compactness makes it a grab-and-go, casual outing device.

On that note…

The DSLR obviously has more physical dials and buttons, giving you quicker access to exposure controls, shutter priority, aperture priority, and modes for creative flexibility - a boon for those who like to geek out with manual settings. The superzoom uses mostly menu navigation with fewer tactile controls, so your exposure adjustment and shooting parameters aren’t as immediate or precise.

Sensor Tech and Image Quality: The Heart of the Matter

This is where photographic disciplines usually pivot on performance, and I love getting into sensor data.

The Olympus E-520 features a Four Thirds system CMOS sensor sized at 17.3 x 13 mm with a 10-megapixel resolution (3648 x 2736 max image size). This sensor size is significantly larger than the SP-820UZ’s 1/2.3” sensor measuring 6.17 x 4.55 mm, which shoots at a 14MP max resolution (4288 x 3216). Although the SP-820UZ packs in more pixels, they’re crammed onto a much smaller surface.

Why does this matter to you? Larger sensors generally gather more light and produce cleaner images with better color depth and dynamic range, vital for portraits, landscapes, and pretty much any genre requiring image fidelity.

DxOMark ratings underscore this too:

• E-520 scores a 55 overall with color depth of 21.4 bits, dynamic range of 10.4 EV, and low-light ISO performance up to 548.
• SP-820UZ wasn’t tested, but cameras with tiny 1/2.3” sensors typically lag behind by a wide margin on dynamic range and low-light noise.

In practical terms, when shooting portraits or landscapes, the E-520 clearly pulls ahead with better skin tones and shadow detail. The Stylus’s oversharpened images and noisy high-ISO shots restrict it mostly to bright day shooting or casual snaps.

User Interface and Display: How You See Your Shot

An often underrated factor is the screen and viewfinder setup that helps you compose confidently.

The E-520 features a 2.7-inch fixed LCD with 230k-dot resolution and an optical pentamirror viewfinder covering about 95% of the frame. This viewfinder, though not the brightest or highest magnification (~0.46x), provides a true DSLR shooting experience essential for precise framing in bright outdoor conditions or fast-paced scenes.

Meanwhile, the SP-820UZ skips the viewfinder altogether in favor of a larger 3-inch TFT LCD with 460k-dot resolution, offering a sharper and more vibrant display. The absence of a viewfinder makes it more challenging to shoot in direct sunlight, but it simplifies the body and cuts costs.

Neither model has touchscreens or articulating displays, which feel dated today but were normal at their announcement times. The SP-820’s bigger screen is easier for casual composition and playback, whereas the E-520’s traditional setup appeals to those who prefer eye-level framing.

Autofocus and Shooting Speed: Catching the Moment

Let’s zoom into the AF systems and burst modes, critical for wildlife, sports, and action photography.

Here, the E-520’s hybrid autofocus shines. The DSLR combines 3 phase-detection points with contrast detection for reasonable speed and tracking in well-lit conditions. It supports continuous AF for moving subjects, which I tested extensively by photographing children running and small animals - results were respectable, though nowhere near pro-grade systems.

The SP-820UZ, relying only on contrast detection, feels sluggish. It has fewer customization options and no continuous AF, limiting its ability to lock on fast or erratic subjects, so sports or wildlife enthusiasts will find it limiting.

The burst shooting rate is also faster on the DSLR - 4 fps versus 2 fps - not a blockbuster speed but enough for casual action.

Let’s Talk Lenses: Versatility and Creative Control

No comparison fueled by Olympus cameras is complete without a lens chat.

The E-520 uses the Four Thirds lens mount and supports a vast ecosystem of 45 lenses, including primes with wide apertures, macro lenses, and pro telephoto zooms. This flexibility makes it a toolkit for all genres from studio portraits with creamy bokeh through to landscapes with tack-sharp wide angles.

On the other hand, the SP-820UZ comes with a fixed 40x superzoom lens (22-896 mm equivalent, f/3.4-5.7) which is impressive on paper for sheer reach. However, the variable aperture means less light at the long end, and optical quality can’t compete with prime or high-quality zooms on the DSLR.

If you crave optical versatility or want to grow as a photographer exploring focal creativity, the E-520’s lens mount is a clear winner. But if absolute zoom reach in one tidy package is your jam - think birdwatching from a distance or vacation family photos - the SP-820UZ delivers convenience without juggling lens swaps.

Durability and Weather Resistance: Shooting in Tough Conditions

Neither model is weather sealed or splash/dustproof, unfortunately. Both cameras require gentle handling in challenging environments.

The E-520 is sturdier overall, featuring a compact SLR chassis with a robust feel, while the SP-820UZ’s predominantly plastic construction is lighter and less imposing but also less rugged.

Battery Life and Storage Convenience

The E-520 offers an impressive battery capacity rated at 650 shots per charge, a real boon if you hate swapping batteries mid-shoot at events or on trips.

The SP-820UZ does not specify battery life in its specs, but based on similar compact superzoom cameras, expect roughly 250-300 shots per charge - enough for short outings but not marathon sessions.

Storage-wise, the E-520 supports CompactFlash and xD Picture Cards, which might be a turnoff now as these formats are more niche and slower compared to modern SD cards. The SP-820UZ accepts popular SD/SDHC/SDXC cards, widely available and cost-effective.

Connectivity and Video Capabilities

The E-520 has no wireless connectivity, HDMI, or microphone inputs - typical for an entry DSLR released in 2008. Video recording is not supported, strictly an imaging device.

In contrast, the SP-820UZ includes Full HD 1080p video recording (MPEG-4, H.264) at 30fps, plus slower frame rate options for 480p and 320p footage. No microphone input or wireless options either.

While the SP-820UZ’s video is limited in codec and features, it’s a nice bonus for casual shooters wanting quick clips without buying a separate camcorder.
