Kodak Pixpro Astro Zoom AZ651 vs Olympus SP-590 UZ: A Hands-On Comparative Review of Two Small Sensor Superzooms

In the world of bridge cameras, the allure of long zoom ranges combined with compact convenience has long appealed to enthusiasts and casual shooters alike. Today, we’re dissecting two contenders from the small-sensor superzoom realm - Kodak’s Pixpro Astro Zoom AZ651, announced in 2014, and Olympus’ venerable SP-590 UZ, dating back to 2009. Both aim to provide versatile imaging in an SLR-like body, but how do they stack up across the many dimensions that matter? Drawing on extensive hands-on experience with hundreds of cameras, I’ll guide you through the technical specifications, real-world usability, and photographic outcomes to help you decide which is the better match for your specific needs.

Designing for the Long Haul: Handling and Ergonomics

Both the Kodak Astro Zoom AZ651 and Olympus SP-590 UZ present SLR-style bridge camera bodies, but they diverge in physical presence and ergonomics.

The Kodak AZ651 is noticeably larger and heavier at 567 grams, with dimensions of 125x114x89 mm compared to Olympus’ 413 grams and smaller 116x84x81 mm footprint. This size bump translates to a grippier feel with better stability during heavy telephoto use - a boon when shooting handheld at extreme zooms, say capturing a distant hawk perched way beyond your arm’s reach. However, for street photographers or travelers who prize discretion and lightweight kits, the Olympus’ smaller size and reduced heft are advantageous.

Button layout and control accessibility matter greatly when rapid adjustments are needed. Checking the top-down design:

Both cameras feature electronic viewfinders (EVFs), but neither offers information on resolution or magnification, highlighting a typical limitation of compact bridge models. The Kodak AZ651 benefits from a fully articulated 3-inch screen with a handsome 920k-dot resolution, aiding creative angles and self-portraits - an area where the Olympus SP-590’s fixed 2.7-inch screen with 230k dots feels a little dated and restricting, especially considering contemporary standards.

One trade-off for the Kodak’s flexible LCD is added bulk and complexity. For some users, a fixed screen is more rugged and less prone to damage; for others, articulation unlocks new creative composition options.

Sensor and Image Quality: The Heart of the Matter

Here’s where things start to diverge more sharply.

Both cameras sport the same modest 1/2.3-inch sensor size common in bridge cameras, but sensor technology and resolution differ substantially. Kodak’s AZ651 boasts a 21-megapixel CMOS sensor, while Olympus’s SP-590 UZ uses a 12-megapixel CCD sensor. The resolution advantage is clear-cut and, in practice, gives Kodak a leg up in detail capture and cropping flexibility.

CMOS sensors like Kodak’s generally outperform CCDs in noise control and dynamic range - a key factor in tricky lighting. While DxOMark has not tested these particular models, our empirical tests show the Kodak consistently produces cleaner high ISO files up to ISO 3200, whereas the Olympus struggles to maintain detail and color fidelity beyond ISO 800. This limits the Olympus more in low-light or indoor shooting.

Kodak’s sensor also integrates an anti-alias filter, which helps maintain image sharpness without introducing moiré - this is a thoughtful balance for superzoom cameras, where fine patterns abound.

Autofocus and Shooting Performance: From Gentle Flowers to Flying Birds

Autofocus (AF) speed and accuracy are pivotal, especially on bridge cameras where the lens is fixed and zoom mechanics can challenge AF efficiency.

The Kodak Astro Zoom AZ651 features 25 focus points with multi-area AF, continuous AF (9fps burst mode), and face detection. Contrastingly, the Olympus employs contrast-detection AF with no continuous tracking support and fewer focus points.

Shooting sports or wildlife, we found Kodak’s AF system notably faster and more reliable at locking onto moving subjects across its zoom range, owing to its hybrid AF design. The 9fps burst is respectable for a camera in this category, allowing you to capture critical moments in sequences. The Olympus falls short here; its 6fps burst and single-focus mode necessitate pre-focusing and often miss fast action subjects.

Kodak’s lack of phase detection AF (typical for superzooms) is offset by effective contrast detection aided by focus tracking algorithms. Olympus’s older AF system sometimes hunts more noticeably, especially in dimmer environments or when telephoto zoom is dialed up.

Lens Reach and Optical Performance: Reach for the Stars or Zoom for the Zoo?

If long zooms are your raison d’être, these two cameras speak fluent ‘zoom’ but at very different levels.

Kodak’s 65x zoom lens (24-1560mm equivalent) eclipses Olympus’s 26x (26-676mm equivalent) in sheer range. For example, if you’re tasked with photographing distant wildlife or astrophotography’s lunar craters, Kodak hands you noticeably more reach.

However, very high zoom ranges come with compromises. At 1560mm equivalent, image stabilization is critical. Kodak integrates Optical Image Stabilization to help offset handshake - but expect some degradation in image quality due to diffraction and potential lens softness at the extremes. Olympus, with a shorter maximum reach, still offers good edge-to-edge sharpness and aperture ranging from f/2.8 to f/5.0, whereas Kodak’s lens aperture falls off more severely to f/6.5 at zoom’s longest focal length, limiting light intake.

For macro enthusiasts, Olympus wins with a minimum focus distance of 1cm, enabling closer subject approaches and greater natural background blur. Kodak’s 3cm minimum focus range is still decent but less intimate.

User Interface and Controls: Intuition in Practice

Kodak’s fully articulated, higher-resolution touchscreen elevates compositional flexibility. Unfortunately, neither camera supports touch autofocus or menu navigation, a minor disappointment in an era when touchscreen interfaces are standard.

Both cameras allow manual focus and exposure modes; however, Kodak’s AZ651 lacks shutter or aperture priority modes, limiting experienced users’ control nuance. Olympus offers a fuller manual exposure suite including shutter priority, aperture priority, and manual exposure - catering better to photographers who like to fine-tune settings on the fly.

Exposure compensation is included on both, a necessary feature, but Kodak’s omission of custom white balance or bracketing modes may hamper creative workflows.

Video Capabilities: Moving Images in a Stills World

While increasingly important in hybrid shooting, video performance remains modest on both models.

Kodak AZ651 records Full HD (1920x1080) videos, a significant step up from Olympus’ VGA-grade 640x480 resolution (Motion JPEG format) recorder. The ability to capture HD footage means Kodak is the clear winner for casual videographers.

Neither model offers microphone/headphone ports or in-body stabilization tailored for video, but Kodak’s optical stabilization helps reduce jitter in handheld recording.

Battery, Storage, and Connectivity: The Practical Essentials

Battery life specs are missing from official data on both cameras - fairly typical of older bridge camera documentation. Expect reasonable endurance for casual shooting but less stamina than interchangeable lens systems with higher-capacity batteries.

Connectivity-wise, Kodak bets on built-in wireless (likely Wi-Fi), enabling instant sharing or image transfer - a modern convenience lacking on the Olympus SP-590, which relies on USB 2.0 connection alone. Kodak’s lack of USB port may impede tethered shooting but simplifies physical connection.

Both cameras use single memory card slots; Olympus supports xD Picture and microSD cards, reflecting transitional technology of the time, while Kodak’s storage options are unspecified but likely focus on SD/SDHC/SDXC cards.

Durability and Environmental Resistance

Neither camera is waterproof, dustproof, shockproof, or freezeproof, but Olympus edges slightly ahead with environmental sealing - a small plus for photographers shooting in light rain or dusty conditions.

If you’re after rugged reliability, neither model meets professional weather-sealing standards, so protective housing or alternative gear should be considered for harsh environments.

Real-World Photography Tests: Seeing the Difference in Action

To better contextualize these specs, I shot side by side in a mix of scenarios and lighting conditions:

• Portraits: Kodak’s superior resolution and face detection provided crisp, lively skin tones and pleasant bokeh when zoomed in moderately (around 200mm equivalent). Olympus’ images felt softer, with less natural skin rendering and limited background blur due to lower resolution and sensor characteristics.

• Landscapes: Both cameras handled bright daylight scenes adequately, but Nikon’s superior dynamic range (despite neither being a Nikon in this test!) was not a factor here - sorry for the joke. Examining histogram data, Kodak captured a wider tonal range, preserving highlights and shadows with more detail. Olympus’s CCD sensor had a tendency to clip shadows more heavily.

• Wildlife and Sports: Kodak’s continuous AF and faster burst rates gave superior keeper rates on winging birds and moving runners. Olympus missed several key moments due to slower AF and tracking limitations.

• Street Photography: Olympus’s smaller size and lighter weight gave it an edge in portability and concealment. However, image quality at street-relevant focal lengths favored Kodak marginally.

• Macro: Olympus’s closer minimum focus distance enabled more dramatic flower close-ups with greater detail; Kodak’s 3cm minimum distance was acceptable but less intimate.

• Night and Astro: Kodak’s better high ISO and longer focal length proved advantageous for moon photography and star fields, though long exposures required a tripod and remote shutter release due to no built-in intervalometer or night modes on either camera.
