Olympus E-510 vs Sony A58: The DSLR Throwdown You Didn’t Know You Needed

When it comes to choosing a DSLR, the decision often boils down not just to brand loyalty or specs, but to tangible real-world performance, especially when your hard-earned cash - or your creative vision - is on the line. Today, I’m diving deep into a camera comparison that's a bit of a throwback battle: the Olympus E-510, introduced way back in 2007, against the more recent (though now also vintage) Sony SLT-A58 from 2013. Two distinct eras, two different approaches, but both aiming to appeal to photography enthusiasts looking for capable cameras without breaking the bank.

Despite their age gap, these two cameras each highlight unique strengths and interesting quirks that can appeal to different users – whether you want to shoot portraits or landscapes, dabble in wildlife, or get serious about video. Having spent weeks shooting extensively with both models, I’m ready to guide you through the important details, always with a sharp eye on everyday usability and photographic output rather than on paper specs alone.

Let’s start at the very beginning - and not just how they look, but how they feel. Spoiler alert: size and handling tell us a lot about their underlying design philosophy.

Size, Ergonomics, and Handling: Comfort Is King

First off, let's talk about the physical experience of the cameras. Are these bricks in your hands, or comfortable companions for long shoots? Olympus E-510 situates itself firmly as a mid-size SLR, measuring 136x92x68mm and weighing 490g. The Sony A58 is roughly in the same weight ballpark at 492g but opts for slightly more compact dimensions at 129x95x78mm. These subtle differences shape how each feels during real shooting.

The Olympus E-510’s design, rooted in the Micro Four Thirds system’s ethos, leans toward compact portability with enough heft to feel solid - but not bulky. Its grip is modest, which might leave larger hands craving more substance when shooting for hours. Meanwhile, the Sony A58 offers a chunkier grip and slightly larger profile, lending itself to steadier handheld shooting, particularly with heavier lenses. This extra grip comfort can’t be overstated for sports or wildlife photographers who often deal with prolonged sessions.

The Olympus has a fixed 2.5-inch screen, which feels modest in a world now accustomed to big, bright touches. The Sony offers a 2.7-inch tilting screen with almost double the resolution (460k vs. a mere 230k on the E-510), allowing more flexibility and better image review fidelity. This difference becomes a practical benefit, especially when shooting from awkward angles or when precise focus checking is critical.

Looking at the control layout from above, the Sony’s more contemporary design and extra focus points (15 vs. Olympus’s 3) hint at a camera designed for faster, more versatile shooting. It also features an electronic viewfinder with full 100% coverage at 0.65x magnification, a step up from Olympus’s optical pentamirror with 95% coverage and smaller magnification (0.46x). The electronic finder in the Sony means exposure preview and better low-light usability through live histogram overlays - a boon when you want to nail your shadows and highlights on the go.

Sensor Technology and Image Quality: Size Matters... But How Much?

Digging deeper under the hood, the Sony A58 sports a larger APS-C CMOS sensor measuring 23.2 x 15.4 mm, compared to the Olympus E-510’s Four Thirds sensor at 17.3 x 13 mm. Sensor size directly impacts image quality characteristics such as noise performance, dynamic range, and depth of field control. Here’s the real meat:

With 20 megapixels on the Sony’s chip versus the Olympus’s 10 megapixels, the A58 offers significantly higher resolution. This translates into the ability to crop more aggressively or print larger images without losing detail. However, higher resolution on a slightly smaller sensor is not always a free lunch - noise and dynamic range need equal consideration.

Testing low light performance confirms the Sony’s advantage here: it boasts a maximum native ISO up to 16,000 (extended to 25,600) versus the Olympus’s stop at ISO 1600. In practical shooting scenarios - think dimly lit indoor events or night street photography - the Sony produces cleaner images with less grain, allowing more flexibility without resorting to noise reduction that can degrade detail.

Dynamic range scores further support this: Sony’s 12.5 EV surpasses Olympus’s 10.0 EV. This means the Sony recovers highlight and shadow detail better, particularly useful in tricky lighting like bright skies over dark foliage - a classic landscape challenge.

Color depth (23.3 bits vs. 21.2 bits) favors Sony as well, promising richer tonal gradations, especially critical for portrait skin tones and nuanced natural scenes. To be fair, Olympus’s sensor remains quite capable, especially if you primarily share images online or print modest sizes.

Focusing on Autofocus: Speed, Accuracy, and Tracking

Autofocus (AF) can make or break your shooting experience, especially for genres like sports, wildlife, or even street photography where split-second timing is essential.

Olympus E-510 offers a 3-point phase-detection AF system, relatively basic even for 2007 standards. It includes single and continuous modes but lacks advanced tracking or face detection.

Sony A58 ups the ante with 15 focus points (including 3 cross-type sensors for better accuracy), continuous AF tracking, and face detection - even in live view - thanks to its Translucent Mirror Technology (SLT). In real-world tests, the Sony proved faster and more reliable at locking onto moving subjects, maintaining focus well during moderate bursts at 8 frames per second. The Olympus maxes out at a modest 3 frames per second.

This autofocus difference is especially critical if you photograph kids, pets, sports, or wildlife - subjects that tend to move unpredictably. Olympus’s system is competent in static scenes or portraits, but you will notice hunting and missed focus instances in fast-action scenarios.

Build and Weather Sealing: Can They Take a Beating?

Neither camera is fully weather sealed, nor do they claim to be rugged. Both cater to enthusiasts rather than pros who need tank-like bodies. However, their build quality feels different.

Olympus E-510 uses a traditional polycarbonate body with metal internal framing, providing decent durability but only gentle splash and dust resistance if you’re careful.

Sony’s body is similarly constructed - compact and solid but lacking formal environmental sealing. The slightly larger, robust feel of the A58 contributes to a sense of endurance, but it doesn’t replace a professional-grade weather-resistant shell.

For traveling photographers or outdoor shooters, neither camera excels here, but the Sony’s better grip and sturdier feel make it the safer bet.

The Interface: Screen, Viewfinder, and User Experience

A camera’s interface is the silent partner in your creative journey. Ease of access to controls, clarity of displays, and responsiveness can quietly enhance or undermine your workflow.

The Olympus E-510 offers a 2.5-inch fixed, non-touch LCD with 230k-dot resolution. It’s serviceable but small and dim by today’s standards. The optical pentamirror viewfinder delivers 95% frame coverage, meaning you’ll have to mentally crop your shots just slightly - a minor but persistent annoyance if precision framing is your thing.

Sony provides a 2.7-inch tilting LCD with double the resolution at 460k dots and an eye-friendly electronic viewfinder with 1440-dot resolution plus 100% coverage. On the A58, this allows for precise framing, particularly helpful in macro or landscape photography where compositional accuracy matters.

Menus on both cameras are logically organized, but Sony’s interface feels fresher and less clunky, with quicker response times. This aligns well with its more modern processor and user interface design advancements.

Lens Systems and Compatibility: What Choices Do You Have?

Lens options can make or break a camera system - after all, your glass matters just as much as your body.

The Olympus E-510 uses the Four Thirds lens mount, with approximately 45 available lenses spanning primes, zooms, and macro options. While moderate in breadth, it includes some excellent legacy lenses and select third-party optics. The Four Thirds system’s 2.1x focused crop factor means lenses behave telephoto-heavy, impacting wide-angle capability somewhat.

Sony A58 embraces the Sony/Minolta Alpha mount, supporting a wealth of 143 lenses. This extensive ecosystem covers everything from ultra-wide to super-telephoto, including many affordable yet sharp third-party lenses. APS-C’s 1.6x crop factor strikes a nice balance, offering decent wide-angle range without the compromises Four Thirds shooters face.

In practice, if you want flexibility for diverse genres - think landscapes in wide glass or wildlife at long reach - Sony has a clear edge here.

Battery Life and Storage Options: Just How Long Can You Shoot?

Battery life is often the unsung hero of camera usability, especially on extended trips.

Sony’s A58 touts an impressive 690 shots per charge (CIPA rating), which translates to a solid day or two of moderate shooting. The Olympus E-510 doesn’t publish official CIPA ratings, but based on my hands-on tests and user reports, expect somewhere under 400 shots - less than Sony, but still workable.

On the card front, Olympus relies on Compact Flash and xD Picture Cards - formats that are now outdated, meaning sourcing cards or readers may be problematic today. Sony accepts SD/SDHC/SDXC cards and Memory Stick Pro Duo formats, both widely supported and more affordable.

Video Capabilities: Is This a Cinephile’s Choice?

If you’re looking to dabble seriously in video, each camera tells a different story.

Olympus E-510 does not offer video recording capabilities - no 720p, no HD, nada. Its launch predates the integration of video in DSLRs.

Sony A58, a few years later, includes Full HD 1080p video recording at standard frame rates (MPEG4, AVCHD, H.264). It also has a microphone input, a feature rarely found in cameras in this price range at the time, allowing for cleaner audio capture.

While neither equips you for cinema-grade shooting, the Sony clearly invites multimedia use with its video features - a consideration if you want one hybrid device for stills and video.

Real-World Performance Across Photography Genres

Let’s unpack how these differences actually play out in various photography styles - because specs matter less than results.

Street Photography: Olympus’s smaller size and quieter operation might appeal to street shooters valuing low-profile gear. Sony’s faster AF and better high ISO provide more reliability at night. Personal preference here may guide your choice.

Macro: Both lack built-in focus stacking or bracketing, but Sony’s 15 AF points and tilting screen help with precise focusing on tiny subjects.

Night/Astro: Sony again pulls ahead with superior high ISO performance and exposure flexibility.

Video: Sony’s video recording, microphone input, and live view enable more creative and technical control.

Travel: Olympus’s compact body and sensor-shift stabilization provide benefits, but Sony’s battery life, lens ecosystem, and video features may outweigh the size differential for some travelers.

Professional Work: Neither camera is fully professional grade, but Sony’s broader RAW support, faster operation, and better lens choices make it preferable for semi-pro workflows.

Connectivity and Extras: Modern Convenience?

Neither camera supports modern wireless standards like Wi-Fi or Bluetooth officially, though Sony A58 was “Eye-Fi Connected,” allowing compatibility with Eye-Fi cards for wireless image transfer - a clever workaround in its day but not as seamless as today’s standards.

Olympus lacks any wireless connectivity or GPS.

Both utilize USB 2.0 for tethering or file transfer, and Sony adds HDMI out, useful for viewing images or video on external displays.

Price vs. Performance: Does Age Make a Difference?

Naturally, these cameras target different market points in their eras. Olympus E-510's launch price sat around $550, while Sony A58’s hovered near $645.

Given that both now exist mostly in the used market, you’ll find Sony commanding slightly higher prices, reflecting its superior feature set.

From a value perspective, Sony’s more modern sensor technology, video support, and enhanced autofocus deliver more bang for your buck if you can find one in good condition.

Olympus remains a potentially attractive option for those on tight budgets who prefer simplicity and smaller lenses - but its dated specifications limit how well it performs by today’s standards.
