From Pocket-Sized Snapshots to Pro Beast Mode: Comparing the Sony A99 II and Sony W370

Imagine, two Sony cameras walk into a room: on one side, the Sony Alpha A99 II, a veritable powerhouse of professional DSLR imaging. On the other, the diminutive Sony DSC-W370 compact, a cheerful point-and-shoot built for simplicity and portability. Both share a Sony badge, but their DNA, capabilities, and user aims couldn’t be more different - almost like comparing a thoroughbred racehorse with a city scooter. Yet, therein lies the fascination for anyone serious about photography gear: how do these two cameras, separated by a gulf of specs and ambitions, compare when put under the microscope of real-world use?

I’ve logged thousands of hours testing cameras both big and small - evaluating sensors, autofocus systems, ergonomics, and much more. In this comprehensive, 2500-word breakdown, I'll unpack what the high-end A99 II and entry-level W370 bring to the table across portraiture, landscapes, wildlife, video, and more. Along the way, seven carefully chosen images will help illustrate key points. Whether you’re a pro photographer, a passionate enthusiast, or just someone hunting the perfect camera for your style and budget, this comparison will guide you through the strengths, weaknesses, and essential differences - minus the marketing fluff.

Getting Hands-On: Size, Build, and Controls

Right out of the gate, the physical contrasts couldn’t be more obvious. The Sony A99 II is a mid-size DSLR, weighing in at 849 grams with robust magnesium alloy construction and weather sealing. The Sony W370 is a featherweight 179 grams compact aimed at snap-happy travelers looking for max convenience.

Handling the A99 II is a tactile joy: a firm grip, well-placed buttons, and a 3-inch fully articulated LCD screen that flips out to all angles - perfect for shooting creative perspectives or shooting video. The W370 offers a fixed 3-inch screen but at a low resolution (230k dots), and honestly, it feels a bit dated and plasticky in comparison.

Checking out the control layout from above (always a revealing angle), the A99 II sports dedicated dials for shutter speed, exposure compensation, and ISO - absolute essentials when you want quick, intuitive adjustments on the fly. The W370 dispenses with nearly all manual control in favor of simplicity: it’s a point-and-shoot through and through.

For enthusiasts who love having customizable buttons, precise dials, and effortless access to settings - the A99 II's thoughtfully designed interface is a joy. The W370 is content with a minimalistic approach that works if you want to "shoot and forget," but you absolutely lose flexibility.

Sensor Showdown: Size, Resolution, and Image Quality

Here lies the heart of any camera comparison: the sensor and its impact on image quality.

The Sony A99 II boasts an impressive 42.4-megapixel full-frame BSI CMOS sensor - measuring a sprawling 35.9 x 24 mm. This sensor is large territory for light to hit, offering superb dynamic range, color depth, and noise control. According to DxOMark, it achieves a 25.4 bits color depth and a 13.4 EV dynamic range, with stellar sensitivity up to ISO 25,600 native and extendable.

The W370, by contrast, has a tiny 1/2.3-inch CCD sensor with 14 megapixels and a modest size of just 6.17 x 4.55 mm. Needless to say, the tiny sensor yields far lower dynamic range, more noise at higher ISO, and diminished detail - typical for compact cameras of that era.

In real-world shooting, the full-frame of the A99 II translates to luscious image files bursting with detail and nuance - a must for landscape photographers wanting rich shadow detail or portrait shooters craving skin-tone fidelity. The W370 is better suited for casual snaps where you don’t plan to heavily crop or print large.

Seeing Is Believing: Viewfinders and Screens

Ergonomics doesn’t end with size and buttons. What about eyeball experience? The A99 II features a high-resolution electronic viewfinder (EVF) with 2.36 million dots, excellent refresh rates, and 100% frame coverage. This EVF mimics the optical viewfinders of DSLRs but with modern perks like live exposure preview and focus aids.

The W370, being a budget compact, scrapes by with no viewfinder at all - you compose solely on that modest 230k-dot LCD.

Using the A99 II’s EVF feels akin to looking through a window into the scene - crisp, bright, and allowing precision framing even in glaring sunlight. The articulated touchscreen adds creative angle flexibility, which is a boon for macro or video shooters. The W370’s fixed screen can be frustrating outdoors or in fast situations, with limited viewing angles and dim brightness.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portraiture puts a camera’s sensor, autofocus, and lens quality to the test. The A99 II shines with its combination of 42MP detail, 5-axis sensor-based image stabilization, and a 399-point autofocus system featuring 79 cross-type points - remarkable even by today’s standards.

One feature I’m always eager to test is eye autofocus - a game-changer for critical portraits. The A99 II offers reliable face detection but lacks dedicated animal or eye AF modes found in later models. Still, its sophisticated AF system tracks human eyes with high accuracy, enabling tack-sharp focus on subjects, even in dynamic settings.

The W370, on the other hand, has a pedestrian 9-point AF system (center weighted), with no eye or face detection - in portrait mode, focusing is slower, less accurate, and bokeh is essentially non-existent given its smaller sensor and fixed lens.

Portrait photographers after creamy, smooth background blur will want to invest in the A99 II’s vast native lens lineup - including high-end Sony/Minolta Alpha mount primes and zooms - providing f/1.4 or f/2.8 apertures ideal for beautiful subject separation. The W370’s lens maxes out at f/3.6-5.6, so background separation and low-light performance are compromised.

Into the Wild: Autofocus Speed and Burst Performance for Wildlife and Sports

For wildlife and sports shooters, speed and tracking prowess are paramount. You need a camera that locks focus and shoots frames as fast as your eye can follow.

The A99 II boasts an impressive 12 fps burst rate with continuous AF and exposure, thanks to its powerful Bionz X processor and phase-detection AF system with 399 focus points covering a large portion of the frame. This enables confident tracking of fast-moving subjects like birds in flight or athletes mid-stride.

The W370’s 2 fps continuous shooting barely qualifies for sports use, and autofocus is contrast-detection based, which is slower and less accurate for moving subjects. There’s no phase-detection AF, no tracking modes, and no burst optimization.

This gap makes the A99 II the clear winner for action photography - its rugged build and weather sealing add peace of mind shooting in unpredictable outdoor conditions.

Landscapes and Macro: Resolution, Stability, and Focus Precision

Landscape photographers often crave high resolution for large prints, paired with dependable weather sealing for shooting in wet or dusty environments. The A99 II’s 42 MP sensor and sealed body checks those boxes nicely. Weatherproofing means you can venture into fog, drizzle, or dusty trails without fearing immediate failure.

Macro shooters will appreciate the A99 II’s sensor-based 5-axis image stabilization system, which mitigates hand shake at close focusing distances - critical when shooting at high magnifications. The articulated screen also aids tricky compositions from low or high angles. Focus stacking isn’t available as an in-camera feature, but tethered capture and post-processing can fill that gap.

The W370 offers none of these advanced features: no weather sealing, no stabilization as effective as a DSLR’s sensor-based system, and no specialized macro modes beyond a fixed minimum focusing distance. Its sensor and optics just don’t provide the requisite detail for fine macro work.

Night and Astro Photography: ISO Performance and Exposure Options

Long exposures and low-light shots put sensors and noise reduction processing under the microscope.

The A99 II’s native ISO sensitivity from 100 to 25,600 (expandable to 102,400) and excellent low-light noise performance (DxOMark low-light ISO score of 2317) let me shoot handheld in dim ambient light without excessive grain. Its manual exposure modes, shutter priority, and exposure compensation options enable precise control for star trails or nightscapes. I’ve often used it for milky way shots with stellar results.

Conversely, the W370’s maximum ISO 3200, poorer noise handling, and limited shutter speed range (max 1600) awkwardly curtail night shooting. Its reliance on Motion JPEG video compression and absence of raw support also restrict post-processing latitude.

Video Capabilities: Resolution, Stabilization, and Audio

Despite the A99 II being announced back in 2016, its video chops remain solid. It offers 4K UHD video at 30 fps, HDMI clean output, and microphone plus headphone ports for sound monitoring and external mics - essential for professional video workflows. The sensor-based 5-axis stabilization greatly smooths handheld shooting.

In contrast, the W370 tops out at 720p HD video at 30 fps, capturing in Motion JPEG format, with no stabilization dedicated to video and no external audio inputs. In short, the W370 is fine for casual clips but can’t compete in serious video production.

Traveling Light: Versatility and Battery Life

Travel photography demands a camera that balances image quality, portability, battery endurance, and storage flexibility.

The A99 II, though relatively compact for a full-frame DSLR, weighs nearly a kilogram (849 g) and measures 143x104x76 mm. It offers dual card slots for SD/Memory Stick and a solid battery life rated at about 490 shots per charge - very respectable for travel shoots.

The W370 is pocketable (100x57x26 mm), ultra-light at just 179 g, and designed for grab-and-go snapshots. However, its single card slot and relatively modest battery life limit extended shooting days.

For travel photographers prioritizing high quality and versatility, the A99 II is a superior tool, albeit bulkier - but if minimizing packing weight and expense trumps image fidelity, the W370 holds its own as a capable compact tourist companion.

Professional Workflow: File Formats and Reliability

Pro photographers need reliable cameras with extensive file format support and durable design.

The Sony A99 II writes full-resolution 14-bit RAW files compatible with all major post-processing tools, crucial for maximizing image editing latitude. Its body is weather sealed and constructed from durable lithium-ion powered materials for tough, all-weather assignments.

The W370 shoots only JPEGs - no raw support - and lacks protective sealing or shock/freeze durability. Its fixed lens and limited manual control make it unsuitable for professional clients or demanding shoots.

Connectivity and Storage Options: Modern Conveniences

The A99 II includes built-in Wi-Fi, Bluetooth, and NFC, allowing seamless wireless image transfer and remote control via compatible apps - a blessing for workflow efficiency.

The W370 offers basic USB 2.0 and HDMI output but no wireless options, reflecting its era and price point.

Dual SD card slots on the A99 II enhance flexibility, enabling backup storage or overflow capacity for exhaustive shoots - a welcome feature professionals rely on.

Price vs Performance: Making Sense of the Investment

At street prices, the Sony A99 II commands around $3200, while the W370 was priced near $230 (when available new). This wide gulf reflects fundamentally different target buyers: professionals and advanced amateurs versus casual snapshot takers.

If your photographic ambitions require top-tier image quality, autofocus sophistication, and feature-rich operation, the A99 II justifies its expense and complexity. But if you want an ultra-easy, budget-friendly camera for casual family snaps or travel memories without fuss, the W370 still has some charm.

Performance by Photography Genre: Who Wins Where?
