Olympus E-450 vs Sony A68: A Deep Dive into Two Entry-Level DSLRs Across the Photography Spectrum

In the landscape of entry-level DSLRs, the Olympus E-450 and the Sony A68 occupy unique niches shaped by their technological eras, manufacturer philosophies, and design priorities. As someone who has spent over 15 years testing and comparing cameras through the lenses of sensor technology, autofocus performance, and usability across genres, this comparison aims to bring clarity for photographers scouting for a dependable, affordable DSLR.

We'll unpack each camera’s strengths and shortcomings through both technical evaluation and real-world usage, layering insights across portrait, landscape, wildlife, sports, street, macro, night, video, travel, and professional work scenarios. By the end, you should have a clear understanding of which system better suits specific needs and budgets.

Let’s start by sizing them up holistically.

First Impressions: Size, Ergonomics, and Build

The Olympus E-450, released in early 2009, embodies compactness and lightweight design - an essential trait from Olympus’s heritage with Four Thirds and later Micro Four Thirds systems. Its dimensions of 130 x 91 x 53 mm and weight of just 426g make it noticeably more pocketable than the Sony A68’s bulkier 143 x 104 x 81 mm and heftier 610g.

In hand, the E-450 feels nimble and suited for beginners or travelers prioritizing light packs. The grip is smaller but comfortable enough, especially with smaller primes. In contrast, the Sony A68’s larger body provides a more substantial grip, especially benefiting photographers with bigger hands or those shooting through longer telephoto lenses for extended periods.

Build quality in both cameras is primarily plastic; neither offers weather sealing or ruggedization. Neither is particularly freezeproof, dustproof, or shockproof - fair for their pricing and entry-tier positioning.

I’ve found the A68’s heft lends itself well to stability during telephoto shooting, reducing hand shake. However, Olympus’ compactness wins points for discrete street photography or travel scenarios where packing size truly matters.

Control Layout and User Interface: Intuitive or Clunky?

Ergonomics extend beyond size - control placement and ease of use define the shooting experience. The Sony A68 shows a more modern approach with a tilting 2.7” screen at 461k dots resolution, accompanied by an electronic viewfinder with 1440k dots, 100% coverage, and a 0.57x magnification factor.

The Olympus E-450 has a fixed 2.7” LCD at 230k dots resolution and an optical pentamirror viewfinder offering around 95% frame coverage and 0.46x magnification. The difference in viewfinder quality translates directly to framing confidence and manual focus precision.

Controls are more generously laid out on the Sony A68, including dedicated dials and buttons for exposure compensation, ISO, and a larger mode dial. The Olympus’s buttons are more basic, sometimes requiring more menu diving to access settings, which impacts speed of adjustments - a notable drawback for fast-moving subjects or changing lighting.

From years of fieldwork, I can attest that having a reliable viewfinder and well-positioned controls makes all the difference in genres like wildlife or sports photography where seconds count.

Sensor and Image Quality: The Heart of the Output

At the sensor’s core, these two DSLRs are separated by technological progress and sensor size. The Olympus E-450 houses a Four Thirds CMOS sensor measuring 17.3mm x 13mm with a resolution of 10 megapixels and an effective crop factor of roughly 2.1x. In contrast, the Sony A68 features a larger APS-C (23.5mm x 15.6mm) CMOS sensor at 24 megapixels, with a smaller 1.5x crop factor.

This difference alone warrants careful scrutiny. In practical terms, the Sony A68 provides significantly improved color depth (24.1 bits vs. 21.5 bits), dynamic range (13.5 EV vs 10.5 EV), and low-light ISO performance (native ISO up to 25600 with usable results) compared to the Olympus’s ISO ceiling at 1600.

In controlled studio testing with raw files, the Sony’s sensor yields cleaner shadows, better highlight retention, and finer detail rendering, especially noticeable in landscape and portrait images. The Olympus’s smaller sensor introduces slightly more noise and less tonal gradation, limiting its suitability under difficult lighting.

Image resolution of 6000 x 4000 pixels from the A68 brings more cropping flexibility and larger print capabilities than the 3648 x 2736 native output from the E-450. However, the Olympus’s 4:3 native aspect ratio may appeal to some portrait and micro four thirds users preferring that format.

Both cameras have anti-aliasing filters, slightly softening detail to prevent moiré, typical for this class.

The Rear Screen and Viewfinder: Critical for Composition and Review

Beyond resolution, the Sony A68’s electronic viewfinder (EVF) offers real-time exposure previews, focus peaking, and other digital aids that complement live view shooting. The Olympus’s optical pentamirror viewfinder is more traditional - offers no exposure preview - and coupled with its lower 95% coverage, it leaves some room for error in composition.

On the rear, the Sony’s tilting LCD - while neither touchscreen nor hi-res compared to modern cameras - gives flexibility for high or low-angle shooting, aiding street and macro photographers.

The Olympus’s fixed LCD and lower resolution hamper quick image review fidelity, potentially leading to repeated shots on uncertain exposures or focus in the field.

Autofocus Systems: Precision and Speed Under Pressure

Here, the difference between these two cameras becomes palpable. The Olympus E-450 features a 3-point autofocus system with phase-detection AF coupled with contrast detection in live view. It supports single and continuous AF, but neither tracking nor face detection is available. This contrasts sharply with the Sony A68’s 79-point phase-detection AF system, including 15 cross-type points, face detection, and continuous tracking AF.

This difference translates to the A68 vastly outperforming the E-450 in action and wildlife shooting.

Both implement AF during live view, but the Sony’s system is faster and more reliable. The E-450’s AF can hunt under low contrast and is slower to lock focus, especially problematic for moving subjects.

Burst Shooting and Buffer: Catching the Decisive Moment

If you’ve ever tried to photograph fast-paced moments, you know the value of continuous shooting capabilities. Olympus’s maximum burst rate rests at 4 frames per second, while Sony pushes 8 fps - doubled capacity for sports or wildlife enthusiasts.

Both cameras capture JPEG and raw formats, but Sony’s buffer depth is significantly larger, allowing longer bursts without dropping frames. For subjects like birds in flight or fast-moving athletes, the Sony A68 is the clear winner here.

Lens Ecosystem and Compatibility

A robust lens system greatly influences versatility. The Olympus E-450 uses the Micro Four Thirds mount, inheriting compatibility with over 45 lenses from both Olympus and Panasonic, ranging from affordable primes to weather-sealed pro zooms.
