Olympus E-30 vs. Olympus E-510: A Deep Dive into Two Mid-Size DSLRs for Photography Enthusiasts

Having tested both the Olympus E-30 and E-510 thoroughly over the years, I find this comparison a rewarding challenge because these cameras sit in a fascinating overlap area of Olympus’s DSLRs - both appealing to eager enthusiasts yet offering distinctly different packages. Whether you’re a cheapskate looking for a capable backup body or a serious shooter pondering an upgrade, this head-to-head breakdown will arm you with practical insights grounded in hands-on experience.

Let's unravel the nuts and bolts, the real-world performance nuances, and where each camera shines or sags. By the end, you’ll have a crystal-clear idea of which Olympus SLR deserves a spot in your gear bag.

Making Sense of the Physical Presence: Size, Weight, and Ergonomics

To kick things off, size and grip comfort can shape how much fun you have with a camera, especially on long shoots.

• Olympus E-30: Weighing in at 695g and measuring 142 x 108 x 75 mm, the E-30 feels substantial yet balanced in hand. Olympus positioned it as a mid-size DSLR with an ergonomic grip that fits a broad range of hand sizes comfortably. Its more pronounced, sculpted grips and slightly bigger body contribute to a confident hold.

• Olympus E-510: Lighter and smaller at 490g and 136 x 92 x 68 mm, the E-510 is appealing for travel and street shooters who appreciate a lighter kit without sacrificing handling too much. However, the smaller chassis can feel a bit less solid and sometimes less intuitive to operate, particularly if you wear gloves or prefer clubs for thumbs.

Hands-On Take:

While the E-510’s portability is a clear asset, I tend to prefer the E-30 for marathon shoots. The E-30’s heft isn’t a burden but a design feature that encourages stability and control - no flailing fingers, and you get more precise manipulations of dials without clawing at the camera.

Buttons, Dials, and Control Layout: How Friendly Is the Interface?

Controls make or break your shooting flow. A camera packed with buttons but poorly laid out can slow you down - or worse, make you abandon settings tweaks mid-shoot.

• E-30’s Control Suite: Offers a fully articulated 2.7" HyperCrystal II LCD (more on that shortly), a top screen, and a healthy number of dedicated dials with reasonably illuminated buttons (though not backlit). The additional controls cater to shooters who like to wrestle with manual exposure or switch modes quickly during demanding shoots.

• E-510’s Control Suite: Features a fixed 2.5" LCD and more minimalist button layout. It lacks a top display entirely and limits direct access to some exposure functions without digging into menus. This is common on entry-level to advanced entry-level models but can be frustrating during fast action or when shooting in tricky light.

Ergonomically speaking, the E-30 feels like the camera Olympus designed for users craving mid-level manual control without the bulk of pro bodies. The E-510 veers toward simplicity for budget-conscious buyers or beginners.

Sensor and Image Quality: What Your Photos Will Look Like

Here’s where things get interesting for image quality fanatics and pixel peepers alike.

• Sensor Size and Resolution: Both cameras use Four Thirds-format CMOS sensors (17.3 x 13 mm), meaning they share the same sensor area (224.9 mm²). The E-30 edges out slightly with a 12 MP resolution (4032 x 3024) against the E-510’s 10 MP (3648 x 2736), which translates into a modest bump in image detail and cropping flexibility.

• Image Processor: The E-30 sports the TruePic III+ processor, providing better noise handling, color rendering, and dynamic range performance compared to the unspecified processor in the E-510 (which uses an earlier generation TruePic engine).

• RAW and ISO Performance: Both cameras shoot RAW, a must for professionals and serious enthusiasts wanting full control. The E-30 offers ISO from 100 to 3200, while the E-510 tops out at ISO 1600. Real-world tests show the E-30 producing cleaner images at higher ISOs with less chroma noise - ideal for low-light or indoor shoots.

• Dynamic Range and Color Depth:

  According to DxO Mark metrics:

  • E-30 scores 55 overall, with 21.3 bits color depth and 10.4 stops dynamic range.
  • E-510 scores 52 overall, with 21.2 bits color depth and 10 stops dynamic range.

While these don't scream a vast gulf in quality, the E-30’s advanced sensor and processor combination grants a slight but notable edge for image quality purists.

On-Screen Experience: LCD and Viewfinder Considerations

Now, the means by which you frame and review your shots greatly affect your workflow.

• E-30: Features a fully articulated 2.7-inch screen with 230k dots, using Olympus’s HyperCrystal II LCD technology, which translates to crisp preview clarity even under harsh daylight. The articulation aids macro photographers or low/high angle shooters by providing flexibility previously rare in DSLRs of this class.

• E-510: Sports a fixed 2.5” screen at the same 230k dot resolution, but no articulation. It’s serviceable for framing, but frankly, feels dated compared to the E-30. Outdoor visibility is a bit poorer, especially under direct sun, making composition more guesswork at times.

• Viewfinders: The E-30 optically frames roughly 98% of the scene through a pentaprism viewfinder with 0.56x magnification. The E-510 uses a pentamirror finder, covering 95% at 0.46x magnification. The difference here is tangible; the E-30 provides a brighter, clearer view, which inspires confidence when focusing manually or assessing composition outside of live view.

Autofocus and Shooting Performance: How Fast and Accurate?

A critical factor for disciplines like wildlife and sports.

• E-30: Offers 11 autofocus points with face detection and contrast plus phase detection AF sensors, enabling intelligent focusing modes. It boasts continuous shooting rates of 5 fps, a respectable figure for mid-tier DSLRs of its era.

• E-510: Has only 3 autofocus points without face detection or contrast detection and shoots at a maximum of 3 fps continuous burst.

This makes the E-30 noticeably more capable when tracking moving subjects or working in live view mode. The larger AF array and face detection shine during portrait shoots and street photography work where quick acquisition is key.

Real-World Genre-Specific Analysis

Let’s take our technical specs and blend them into actual photographic scenarios.

Portrait Photography

Portrait lovers emphasize skin tone rendering, smooth bokeh, and precise eye detection.

• E-30: Thanks to its advanced AF with face detection, it nails eye autofocus locking, freeing you to concentrate on composition. The sensor and processor combo delivers rich skin tone reproduction with subtle gradations and less post-processing needed. The 12MP resolution gives you enough detail to print large portraits with crispness without overkill that adds noise.

• E-510: Lacks face detection AF and relies on default 3-point focusing. This means less accuracy in busy compositions; skin tone is fairly accurate but slightly less nuanced, and the 10MP resolution is fine for web or small prints but less flexible for cropping.

Landscape Photography

Look for resolution, dynamic range, and ruggedness.

• E-30 offers the better dynamic range at 10.4 stops, meaning it preserves highlights and shadows nicely even in challenging light. Its articulated screen really helps shoot precarious angles, such as low ground shots or under fences. However, neither E-30 nor E-510 has weather sealing, so carrying weather protection is a must when shooting outdoors extensively.

• E-510’s lower resolution and dynamic range mean it’s less forgiving when printing large detailed landscapes. Its smaller body and lack of screen articulation could slow your workflow if you enjoy unconventional angles.

Wildlife Photography

You need fast, accurate autofocus, good buffer and decent burst rate.

• E-30’s 5 fps and 11 AF points with face detection are industry-respectable for its release period. Its sensor-stabilization helps with longer lenses (given the 2.1x crop factor). This means you can confidently track birds or mammals and still achieve tack-sharp shots.

• E-510 struggles somewhat here. Its 3 AF points offer a narrow focusing field - tracking a moving animal requires practice and patience; burst shooting at 3 fps can miss moments.

Sports Photography

Fast autofocus, high frame rates, and reliable high ISO performance are crucial.

The E-30 outperforms the E-510 on nearly all these.

• E-30’s 5fps continuous can keep up with casual sports action, and higher ISO max means usable images in shadowed or indoor stadium conditions.
• E-510’s maximum shutter speed is 1/4000s vs. 1/8000s on the E-30, giving you more headroom to freeze critically fast motion during bright daylight.
• Better AF coverage and tracking on the E-30 mean fewer lost shots.

Street Photography

Discretion and portability matter here.

• The E-510’s smaller size and lighter weight put it in the lead for street photographers prioritizing a compact package that won’t intimidate subjects.
• The E-30 is bigger but offers silent shooting modes and a quieter shutter - a point in its favor when working in sensitive environments.
• The articulated screen on the E-30 also lets you shoot discreetly from hip level or awkward angles.

Macro Photography

Precision focusing and stabilization come to the fore.

• Both cameras feature sensor-based image stabilization, which helps handheld macro work, but the E-30’s articulated screen stands out for framing tight compositions without contorting yourself.
• The more advanced AF system on the E-30 grants better precision focus, though neither model offers focus stacking or focus bracketing.

Night/Astro Photography

Quality at high ISO and accurate exposures are priorities.

• The E-30 extends to ISO 3200 with more effective noise control and cleaner output, which helps star trail shots or night portraits.
• The E-510 tops out at ISO 1600 and produces noticeably higher noise levels.
• Neither camera features specialized astro modes, but both allow manual exposures and long shutter times, suitable for practice and casual astro work.

Video Capabilities

Neither camera sports video recording - Olympus stayed clear of video with these models.

If video is a core need, these aren’t the cameras to consider. Instead, look at later Olympus offerings or mirrorless bodies.

Travel Photography

Lightweight gear, versatility, battery life, and durability matter.

• The E-510’s smaller footprint and weight make it a tempting travel companion, especially when packing light.
• The E-30 compensates with stronger battery life (approx. 750 shots vs. unknown but presumably fewer on the E-510).
• Both lack environmental sealing, so keep that rain cover handy.

Professional Work Use

Reliability and workflow support come to mind.

• The E-30 offers a 98% viewfinder coverage, top screen, and a faster burst rate, making it more suitable as a second body or even primary affordable DSLR for professionals on a budget.
• RAW support is solid on both.
• The E-30’s superior processor improves workflow efficiency.
• The E-510’s slower burst rates and limited AF points may frustrate demanding pros.

Tech Deep-Dive: Build Quality, Connectivity, and Storage

Build and Weather Resistance

Neither body provides weather or dust sealing. However, the E-30’s more robust construction feels reassuring in the hand, whereas the E-510 has lighter plastic components liable to wear faster.

Connectivity

Both cameras lack wireless features. USB 2.0 ports allow tethered shooting and file transfer but at dated speeds. Neither offers HDMI, Bluetooth, Wi-Fi, or GPS.

Storage Options

Both cameras accept Compact Flash (Type I or II) and xD Picture Cards. CF cards remain viable but can be clunky and expensive compared to SD cards used in recent cameras.

Lens Ecosystem Compatibility

Both cameras use the Micro Four Thirds mount - which is still alive and kicking - offering access to 45+ Olympus lenses and third-party optics.

The 2.1x crop factor makes your typical 300mm lens behave like 630mm in full-frame terms - a boon for wildlife, but be mindful of working distances.

What About Battery Life?

• The E-30’s BLM-1 battery delivers an impressive ~750 shots per charge, rivaling modern mirrorless cameras.
• The E-510’s battery life isn’t officially rated but is understood to be appreciably shorter.

For long fieldwork days, the E-30 clearly offers more shooting time without hunting for backups.

Price-to-Performance Ratio: Stretching Your Photography Dollar

• Olympus E-30: Currently hovers around $1299 (new prices at launch). Today, you can find well-maintained used models much cheaper, but relative to specs, it’s a fantastic mid-tier buy.

• Olympus E-510: More affordable at roughly $550 at launch and even less on the used market, making it an attractive entry for those on a budget.

In my opinion, the E-30 delivers notable value for semi-pros or hobbyists wanting better image quality, speed, and controls - even if the price is higher.

Overall Performance Ratings and Genre Breakdown

Here’s a visual summary collating all these factors.

The E-30 decisively leads in portrait, wildlife, sports, and low-light work, while the E-510’s strengths are in travel and casual street shooting.
