Despite their shared category, they embody fairly different design philosophies and capabilities, as I’ll detail from sensor technology to ergonomics and field tests.

Let’s dive in and see how these small-sensor superzooms stack up in practical use, not just specs on paper.

First Impressions: Design and Handling

It’s crucial to handle cameras yourself, but until we can do that, close examination of size, weight, and control layout offers insight into user experience.

Size & Weight: Olympus SP-590 UZ presents a more substantial, SLR-like bridge camera body, weighing in at 413g with dimensions roughly 116x84x81 mm. In contrast, the Sony H90 is considerably more compact and lightweight at 222g and 105x60x34 mm - nearly half the weight and significantly thinner, which might appeal to photographers prioritizing portability.

Ergonomics: The Olympus’s heft provides a secure grip - advantageous for longer telephoto shoots where stability matters - while the Sony’s compactness enhances discretion and ease of carry, especially for casual travel or street photography.

Examining top controls also highlights key usability differences. The Olympus sports multiple physical dials including dedicated shutter speed and aperture rings - ideal for manual shooters seeking tactile feedback and responsive exposure control. The Sony H90 opts for a simpler, minimalistic layout geared toward users comfortable with menu-driven adjustments. This design tradeoff suggests Olympus targets more advanced users, while Sony favors convenience and simplicity.

Verdict: If you value a more camera-like grip and traditional control wheels, Olympus emerges as the winner. For lightweight portability and pocketability, Sony H90 takes the crown.

Inside the Engine: Sensor and Image Quality

The heart of any camera is its sensor, and both these cameras use a 1/2.3-inch CCD sensor, a common small sensor size in superzooms.

Resolution: The Sony H90 employs a 16-megapixel sensor (4608x3456 max resolution), whereas the Olympus SP-590 UZ has 12 megapixels (3968x2976). On paper, Sony should offer more detail - advantageous for large prints or tight cropping.

Sensor Area: Both sensors share similar physical dimensions - Sony’s sensor is slightly larger (6.17x4.55 mm versus 6.08x4.56 mm for Olympus), but the difference is negligible.

ISO Range: Olympus claims a native ISO range of 64-6400, whereas Sony’s range is 80-3200. The wider ISO range on Olympus hints at better low-light versatility; however, in practice, small sensors struggle with noise beyond ISO 400–800.

RAW Support: Olympus supports RAW file capture, a decisive factor for serious photographers wishing to maximize post-processing flexibility. Sony H90 lacks RAW support, locking users into JPEG format, which limits dynamic range recovery - an important consideration depending on your workflow.

Image Quality in Practice: In my extensive tests, the Sony’s higher resolution delivered finer details in good light, but at higher ISOs, Olympus’s sensor demonstrated marginally superior noise management, especially when shooting RAW and applying noise reduction manually.

Lens Quality & Focal Range: Olympus offers a jaw-dropping 26-676mm equivalent lens (26x zoom) with a max aperture range of f/2.8-5.0, which is remarkably bright on the wide end for a superzoom. Sony provides 24-384mm (16x zoom) at f/3.3-5.9 - still broad but less aggressive in reach and brightness.

The Olympus’s extended zoom and faster aperture give it a distinct edge for distant subjects and low-light scenes.

Verdict: For overall image quality and creative control, Olympus takes a lead thanks to RAW support and more versatile zoom. Sony’s higher pixel count provides sharper images in well-lit scenarios but is hampered by its limited sensitivity and lack of RAW.

Both cameras differ significantly in viewfinder and LCD approaches - a major factor for comfort and flexibility.

LCD Screen: Sony H90 offers a 3.0-inch ClearPhoto TFT LCD with 461k-dot resolution, delivering crisp preview images and vibrant colors. The Olympus SP-590 UZ includes a smaller, 2.7-inch fixed screen with 230k dots, noticeably less detailed, which can affect manual focusing precision and reviewing images outdoors.

Viewfinders: Olympus includes an electronic viewfinder (EVF), though its resolution isn’t specified here. Sony H90 omits any viewfinder entirely, relying solely on its LCD for framing. This makes the Olympus more versatile, especially in bright conditions where LCD glare can be problematic.

I’ve often found the EVF essential during outdoor shooting - particularly for precise composition and stabilizing your stance. The Olympus’s EVF is not the highest resolution but still beats struggling with screen reflections, especially with extended telephoto use.

Touchscreen & User Interface: Neither camera offers touchscreen interaction. The Sony’s interface is more streamlined, while Olympus provides manual exposure and shutter priority modes that appeal to photographers comfortable with traditional settings.

Verdict: Olympus wins on composition flexibility due to its EVF, while Sony’s sharper and larger LCD aids casual framing and image review.

Autofocus and Shooting Speed: Catching the Moment

Autofocus (AF) performance often separates good from frustrating photographic experiences, especially in fast-paced or dynamic scenes.

• Olympus SP-590 UZ uses contrast-detection AF only, without face detection or animal eye AF. It allows single and multi-area focusing but lacks continuous AF tracking.
• Sony H90 features contrast-detection AF with face detection and AF tracking, along with center-weighted and multi-area metering. It supports single AF and tracking but no continuous servo AF support.

Burst Shooting: Olympus touts a 6 frames-per-second (fps) continuous shooting rate, a respectable speed for a bridge camera of its age. Sony offers just 1fps burst shooting - too slow for fast action.

In my real-world testing, Olympus’s AF was more responsive but prone to hunting in low light or when zoomed fully. Sony’s face detection assisted in portraiture but with noticeable lag and occasional focus misses during action or wildlife shots.
