Kodak Astro Zoom AZ651 vs Sony Cyber-shot DSC-HX20V: A Thorough Face-Off of Two Small-Sensor Superzooms

When it comes to small-sensor superzoom cameras, manufacturers often strike a careful balance between reach, image quality, and handling. Today, I’m putting two popular cameras under the microscope: the Kodak Pixpro Astro Zoom AZ651, announced in early 2014, and the slightly older Sony Cyber-shot DSC-HX20V from mid-2012. Both fall into that much-loved category of long zoom bridge cameras, but each takes its own route in design philosophy and feature set.

Having tested thousands of cameras across multiple genres, I approach this comparison not merely as a specs battle but through real-world usability, optical performance, and versatility for different photography disciplines. What follows is my in-depth, side-by-side analysis based on hands-on trials, technical insights, and practical workflows.

Let’s start by getting acquainted with their physicality and design nuances.

Size and Handling: Bulk vs. Portability Showdown

Physically, these two cameras present quite contrasting forms, reflecting different user priorities.

The Kodak Astro Zoom AZ651 sports a bulky, SLR-like bridge camera build with dimensions of 125 × 114 × 89 mm and a weight of 567 grams. This size and heft provide a solid grip and stability, particularly useful when wielding that gargantuan 65x zoom lens. The AZ651 feels rooted and substantial in hand, offering a satisfying heft that many amateurs migrating from DSLRs might appreciate.

On the flip side, Sony’s HX20V is a compact camera with dimensions of 107 × 62 × 35 mm, weighing just 254 grams. It slips easily into a jacket pocket or smaller camera bag. The slim profile and lightweight design make it ideal for on-the-go, casual shooting where bulk is a deterrent.

Ergonomically, Kodak leans into a more traditional DSLR-style body, featuring a pronounced grip and rear controls arranged for shader-friendly access, while Sony opts for minimalist controls tailored for compact shooting but preserving manual focus option for flexibility.

The physical size gulf translates directly into user experience. The Kodak will appeal to those who prefer secure handling over long sessions and need optical reach without added lens weight or bulky tripods. Sony suits users valuing portability and discretion, especially street or travel photographers who prize a less conspicuous setup.

Next, let’s cast a glance from above...

Kodak places numerous physical dials and buttons on top, supporting deeper manual control. Sony's simplified layout favors automatic use cases but still provides manual exposure modes. Both cameras have fully articulated (Kodak) or fixed (Sony) 3-inch LCD screens, which we’ll dissect in the interface section.

Sensor Architecture and Image Quality Realities

At the heart of both cameras lies a 1/2.3” sensor - fairly standard for superzoom compacts - but Kodiak and Sony choose different sensor tech and resolutions:

Kodak’s higher resolution sensor theoretically offers more detail at base ISO but also risks more noise and diffraction issues due to pixel density on a small sensor. The Sony’s BSI-CMOS improves light sensitivity, allowing higher max ISO and generally cleaner low-light results.

Testing in real-world conditions confirms this tradeoff: Kodak’s images yield slightly crisper detail in good light, delivering nicely defined textures and sharp edges - good for landscape and macro shots where resolution helps. However, ISO 800 and above start showing aggressive noise and reduced dynamic range. Sony’s lower resolution but backside-illuminated sensor excels at handling low-light environments, producing cleaner shadows and smoother tonal gradations, an advantage for night street photography or indoor shooting.

Sony’s sensor-specific tech also contributes to better highlight retention, evident in tricky dynamic range scenarios like sunsets or high-contrast portraits.

LCDs and Viewfinders: Framing Through Different Lenses

Viewfinder experience is often overlooked on consumer cameras but remains crucial for composition accuracy and eye-level shooting comfort.

The Kodak Astro Zoom AZ651 offers an Electronic Viewfinder (EVF) with 100% coverage but lacks explicit resolution specs - it’s serviceable but can feel a bit grainy in dim light. Its fully articulated 3” LCD with 920k dots is a winner for flexible framing, especially useful in macro, low angles, or vlogging scenarios. Articulation means you can shoot creatively without contorting your body, plus it supports live view with reliable autofocus and exposure feedback.

Sony HX20V forgoes a viewfinder altogether in favor of a fixed 3” XtraFine TruBlack TFT LCD with 922k dots. The TruBlack technology significantly reduces glare and maximizes contrast outdoors, providing a crisp and bright live image even in direct sunlight. However, the lack of an EVF makes eye-level shooting tricky in bright conditions, potentially disadvantaging users accustomed to composing through a finder.

The Kodak's articulating screen is a decisive plus for vloggers and photographers who shoot at unusual angles - it dramatically expands creative framing options. Sony’s screen excels in color fidelity and contrast but limits compositional versatility due to its fixed nature.

Lens Reach and Aperture: Who’s Got the Zoom Muscle?

Here’s where these superzooms tell different stories: Kodak’s AZ651 boasts a colossal 24-1560 mm equivalent lens with a 65x zoom range, while Sony’s HX20V offers a more modest 25-500 mm equivalent 20x zoom.

Kodak’s 65x zoom is a true marvel on paper and perks up wildlife and astrophotography enthusiasts’ ears alike. Its aperture ranges from f/2.9 at the wide end to f/6.5 at maximum telephoto, which is relatively bright on the wide but narrows significantly at the long end. The lens achieves a macro focus distance down to 3 cm, letting you nail tight close-ups with decent working distance, especially aided by the articulated screen.

Sony’s zoom is less ambitious but balances reach and speed with an f/3.2-5.8 aperture and a macro minimum focus distance as close as 1 cm - excellent for extreme close-up detail shots. The smaller zoom range is offset by generally better optics and faster autofocus, making it more suitable for day-to-day shooting and fast action.

Longer focal length in Kodak means you can pick out tiny subjects on the horizon without changing lenses or hauling bulky glass. But be forewarned - that 65x zoom comes with inherent challenges: lens barrel shake, requiring good image stabilization, and some softness at extreme telephoto focal lengths.

Sony’s 20x zoom lens, though less intimidating, tends to produce sharper images and faster autofocus, owing to the better BIONZ processor and optimized optics.

Autofocus and Burst Performance: Tracking Moving Targets

Autofocus systems on superzoom cameras tend to be contrast-detection based, limiting continuous AF speed and accuracy compared to DSLR-grade phase detection. Here’s how our two contenders fare:

Kodak’s AF system is surprisingly versatile for its class, supporting continuous autofocus during bursts and basic face detection. This makes it moderately adept at tracking slowly moving subjects like pets or casual sports. The burst speed of 9 frames per second is commendable for a camera in its category.

Sony’s camera pushes burst speed slightly higher at 10 fps but lacks continuous AF during those bursts, limiting tracking accuracy. It supports face detection and center-weighted AF but has fewer focus points, which can make acquiring subjects at the edge of the frame more challenging.

In my field testing shooting birds and children at play, Kodak’s continuous AF allowed more keepers in a shoot, while Sony’s faster shuttering excelled for freezing motion but required manual refocusing between frames.

Image Stabilization: Steady Shots at Reach

Superzoom lenses amplify camera shake, making built-in image stabilization critical.

Both cameras offer Optical Image Stabilization (OIS), which significantly reduces blur from hand movement.

Kodak’s system is reasonably effective at wide to medium focal lengths but struggles at the extreme 1560 mm equivalent. Given the extraordinary zoom reach, even minor shake is magnified, so a tripod is recommended for the most telephoto shots.

Sony's OIS is well-tuned across its zoom range, noticeably improving handheld sharpness. The synergy between the BIONZ processor and OIS enables sharp images even in moderate low light.

In practical terms, Sony holds a slight advantage in stabilization consistency, especially for travel and street shooters needing reliable handheld performance without fuss.

Battery Life and Storage Options: How Long and How Much

Kodak does not officially specify battery life, but user experiences suggest moderate longevity - around 300 to 350 shots per charge, depending on usage intensity and LCD screen articulation.

Sony’s HX20V uses a proprietary NP-BG1 battery, officially rated for approximately 320 shots per charge, aligning well with Kodak’s performance. Sony benefits from charging via USB, enhancing convenience during travel.

Both cameras support a single memory card slot. Kodak’s compatibility is unspecified, but Sony accepts multiple popular card formats including SD, SDHC, SDXC, and Memory Stick Duo variants, offering versatile storage options.

Sony also integrates GPS, a boon for travel photographers keen on geo-tagging, while Kodak lacks any positioning features.

Connectivity, Video, and Extras: What Else Is in the Box?

Kodak includes built-in wireless connectivity but lacks Bluetooth or NFC. HDMI output is present for external displays; USB connectivity is missing, which is odd and potentially hinders image transfer ease. No microphone or headphone jacks limit video pros.

Sony compensates with USB 2.0, HDMI out, built-in GPS, and Eye-Fi wireless card compatibility. It supports 1080p Full HD video at 60 fps under AVCHD and MPEG-4 formats, providing smoother video playback and better editing flexibility.

Neither camera supports 4K video or advanced focus stacking features; video options are basic but functional for casual use.
