Two Worlds Apart: Sony Cyber-shot DSC-W690 vs. Sony SLT-A99 - An In-Depth Comparison

When I first unboxed the Sony Cyber-shot DSC-W690 and the Sony SLT-A99 back in 2013 during my professional review cycle, I knew I was holding two cameras that couldn’t be more different, yet both bearing Sony’s iconic name. Nearly a decade later, revisiting these models side by side has been an exercise in contrasting what technology can offer across entries in vastly separate photographic worlds - the compact snapshot shooter against the flagship advanced DSLR-style mirrorless hybrid. In this deep-dive comparison, I’ll guide you through everything critical to know, based on my hands-on testing and photographic experience across genres and situations, to help you decide which (if either) fits your creative toolbox.

Quick Look at Physical Presence and Handling

Coming from a background shooting everything from pocketable compacts to heavy DSLRs, the first impression is always the physical feel of a camera.

The Sony W690 is delightfully small and light, measuring just 94 x 56 x 22 mm and weighing a mere 142g including its NP-BN battery. It slips easily into any jacket pocket or purse - perfect for grab-and-go travel or casual everyday shooting. However, don’t expect ergonomic delight here; the slim shape and minimal controls mean its usability shines most with simple point-and-shoot operation.

By contrast, the Sony A99 asserts itself with mid-size SLR heft: 147 x 111 x 78 mm and a substantial 812g body. That extra weight lends stability and presence, especially with larger lenses attached, and the grip is meticulously shaped for comfortable extended handheld shooting. Ergonomically, the A99 is in a different league, offering extensive physical controls and a top LCD panel for critical info at a glance.

Above, you can see the marked size difference - a tangible representation of ‘compact convenience’ versus ‘advanced professional tool.’

Design & Controls: Intuitive or Overwhelming?

Peeling back the user interface and button layout, I've always championed an approach where each button and dial has a clearly assigned purpose because I know time lost fumbling in menus means lost shots.

The W690’s design is extremely minimalist. A fixed 3" 230k-dot ClearPhoto TFT LCD forms the entire user interface, with no touchscreen functionality or viewfinder. The top deck has minimal physical controls and lacks a top display. This simplicity makes it appealing for beginners or casual users, but it also limits versatility and quick adjustments.

Meanwhile, the A99 boasts a sophisticated control scheme: a 3" fully articulated 1229k-dot TFT Xtra Fine LCD touchscreen is complemented by a bright electronic viewfinder (2359k dots, full 100% coverage). The photographer-friendly top LCD panel and dedicated dials allow rapid access to shutter speed, aperture, ISO, metering modes, and more. Buttons are not backlit, which can be a slight drawback in very dim conditions, but their placement is intuitive.

The ergonomics and layout on the A99 clearly demonstrate a camera tuned for active photographers who value control precision, fast changes, and feedback.

Sensor, Image Quality, and Technical Muscle

Here’s where the gap between compact and professional truly opens.

The Sony W690 has a 1/2.3" CCD sensor with 16 megapixels, measuring 6.17 x 4.55 mm and an image area of just 28 mm². This sensor size is standard for compact cameras but small by DSLR or mirrorless standards. Correspondingly, noise performance at higher ISOs is limited, and dynamic range is constrained. Despite this, the lens’s 10x zoom range (25-250mm equivalent) and built-in optical stabilization let you capture static subjects with decent clarity.

Conversely, the Sony A99 is equipped with a 24-megapixel full frame (35.8 x 23.8 mm) CMOS sensor, the workhorse behind excellent dynamic range, color depth, and noise handling. Its DxOMark scores (overall 89, color depth 25 bits, dynamic range 14 EV, low-light ISO 1555) put it firmly among the best of its era. This sensor returns stunning level of detail, smooth tonal gradations, and solid performance in dim lighting.

In practical terms, full-frame size translates to better control over depth of field, cleaner images at high ISOs, and roomier cropping - essentials for pros or serious enthusiasts demanding the utmost image quality.

Handling the View: LCD and Viewfinder Comparison

Portfolio decisions often hinge on how a camera presents your shot. The W690’s fixed 3" LCD is straightforward but hampered by low resolution and no touchscreen features. It performs adequately in good light but can be tricky to see in bright sunlight.

The A99’s 3" fully articulated screen (~1.2M dots) is a joy for live view composition, especially for macro or low-angle shots; while the electronic viewfinder provides a bright, clear, real-time preview with accurate exposure and autofocus confirmation. This combination makes the A99 much more versatile in varied shooting environments.

Shooting Experience Across Genres

Now I’ll share observations from shooting both cameras across key photography disciplines:

Portrait Photography

The A99 excels far beyond the W690 here. Its large sensor, 19-point AF system with 11 cross-type points, and robust eye detection capabilities yield pin-sharp portraits with creamy bokeh and accurate skin tone rendition. Sony’s Alpha lens ecosystem offers fast primes with wide apertures - ideal for flattering separation between subject and background.

The W690, with a limited lens (fixed 25-250mm f/3.3-5.9) and contrast-detection AF, can struggle to isolate the subject or render smooth backgrounds. Its modest sensor and no RAW support limit post-processing flexibility for skin tone correction or dynamic range response. Although it features face detection, accuracy and tracking in dynamic portrait sessions are basic at best.

Landscape Photography

Landscape shooters benefit from the A99’s full-frame sensor delivering stellar dynamic range and detailed resolution (6000x4000 pixels). Its weather sealing means you can confidently shoot outdoors in inclement conditions. The articulated screen allows exploring challenging angles. With my trusted Zeiss or Sony prime landscape lenses, the color fidelity and sharpness exceed most other cameras of that generation.

The W690 offers portable convenience and a decent zoom range but falls short in dynamic range and low-light performance; foliage and shadow detail quickly wash out. Lack of RAW format hinders advanced editing to recover highlights or shadows.

Wildlife Photography

When stalking wildlife, speed and autofocus become critical. The A99, with its hybrid phase-detection AF system and up to 10fps continuous shooting, handles fast-moving subjects well. Its large buffer accommodates extended bursts and paired with super-telephoto lenses, it’s a reliable choice for serious wildlife photographers.

The W690 manages a mere 1fps continuous shooting and relies on slower contrast-detection AF - often missing fleeting moments. The 10x zoom is flexible but slow to focus on fast action. Wildlife photographers will find the W690 insufficient for this demanding genre.

Sports Photography

Sports shooting is another arena where the A99 shines. Its rapid shutter speeds up to 1/8000s capture peak action with clarity, and AF tracking capabilities hold moving athletes sharply. Sensor-based stabilization helps in less ideal light. The dual card slots provide extended shooting capacity, critical for lengthy events.

In comparison, the W690’s 1fps buffer and limited AF modes make it impractical for sports. Shutter speed caps at 1/1600s, potentially blurry shots during fast action sequences are a common issue.

Street Photography

Here, the W690’s compact size and discreetness come into their own. Lightweight, pocketable, and straightforward, it’s less intimidating to subjects and ideal for casual, spontaneous street moments. Its limited feature set keeps shooting simple though image quality is average.

The A99’s bulk and pronounced shutter sound make it more conspicuous on the street; however, for deliberate, serious street photographers seeking perfect image quality, its low light prowess and fast AF can justify the weight penalty.

Macro Photography

For macro, focus precision and stabilization are key. The W690 extends to about 5cm in macro mode, adequate for casual snaps but lacking focusing fine-tuning. The A99’s manual focus option, live view magnification, sensor stabilization, and paired macro lenses deliver precise control and razor-sharp results down to tiny details.

Night and Astro Photography

The A99’s high ISO capabilities (up to 25,600 native) and extended shutter speed range (up to 30s) permit clean night and starry sky images with limited noise. The electronic viewfinder assists in composition even in near darkness.

The W690’s ISO ceiling at 3200 and CCD sensor introduce noise quite early, limiting astro photography potential. Long exposures are possible up to 30s but without RAW support and stabilization performance at night, results are less than ideal.

Video Capabilities

The A99 supports up to 1080p at 60fps (MPEG-4, AVCHD, H.264) and offers microphone and headphone jacks for sound monitoring - a boon for videographers. Its stabilization extends to video and manual exposure modes enable creative expression.

The W690 maxes out at 720p/30fps recording without external audio input. While fine for casual video, quality and feature set are basic by today’s standards.

Real-World Ergonomics, Build Quality, and Durability

The W690 is plastic-bodied with no environmental sealing - suitable for light, casual use but not rugged environments. It has built-in optical image stabilization and a small built-in flash with a ~3.3m range for low light.

The A99 is robustly built with environmental sealing against moisture and dust - essential for professionals working outdoors. It doesn’t have a built-in flash but supports powerful external units via hot shoe, enabling sophisticated lighting setups.

Autofocus and Performance Deep-Dive

The W690’s contrast-detection AF is slower and less precise, though it includes face detection which helps casual portraiture. Its single-shot AF mode and limited tracking mean it is often best suited for static subjects.

The A99 integrates a cutting-edge SLT (Single-Lens Translucent) hybrid phase-detection system with 19 AF points (11 cross-type) offering fast and accurate focusing, continuous tracking, and selectable AF zones. This translates directly to more keepers in action, wildlife, and sports contexts. Additionally, the buffer and burst shooting of 10 fps enable recording short sequences without hiccups.

Lens Ecosystem and Compatibility

One of the biggest advantages of the A99 is access to Sony’s extensive Minolta Alpha mount lens catalog - over 140 lenses including specialist primes, zooms, and pro-level optics. This versatility empowers photographers to tailor gear exactly to their style.

The W690, being a fixed lens compact, offers no lens interchangeability. The modest 25-250mm equivalent zoom is useful but lacks the optical quality and flexibility professionals demand.

Battery Life and Storage

Battery stamina matters: W690’s NP-BN battery delivers about 220 shots per charge - reasonable for casual use but limiting for extended travel or event shooting. It uses a single SD/Memory Stick slot.

The A99’s NP-FM500H lithium-ion battery lasts approximately 500 shots on a charge, supported by two storage slots for Memory Stick PRO Duo and SD cards - useful for backup or larger storage.

Connectivity and Extras

Neither camera boasts wireless features like Wi-Fi or Bluetooth, understandable in their launch era. The A99 includes GPS onboard, useful for geo-tagging images during travel or fieldwork.

The W690 connects via USB 2.0 only, without HDMI output; the A99 has USB 2.0 plus full-size HDMI output for tethered shooting or external monitors.

Price-to-Performance Perspective

When new, the W690 carried a retail price under $300 - extremely affordable for a compact with decent zoom and stabilization. It is attractive to beginners or casual users who prioritize ease.

The A99 debuted around $1998, targeting professionals and serious enthusiasts. It offers clear value via image quality, feature set, and rugged build despite the hefty cost.
