Sony W370 vs Sony A37: A Thorough Comparison for the Photography Enthusiast

Over the past decade, Sony has carved an interesting path in the camera market, offering everything from compact point-and-shoots to entry-level DSLRs boasting solid specs at an accessible price point. Today, we'll dive deep into two very different cameras from Sony’s lineup: the Sony Cyber-shot DSC-W370, a compact point-and-shoot from 2010, and the Sony SLT-A37, an entry-level DSLR introduced in 2012. This comparison is for photographers seeking a clear understanding of how these cameras fare across varied genres and real-world performance, helping you make a confident buying decision tailored to your needs.

While they share a manufacturer, these cameras are fundamentally different beasts. The W370 is a bite-sized, simple camera - a pocket companion that excels in casual use - whereas the A37 is a more serious tool suited for photographers ready to explore manual controls, interchangeable lenses, and improved image quality. Let’s break down these distinctions in detail.

First Impressions: Size, Handling, and Ergonomics

Handling matters. It shapes our connection to the camera and our shooting experience. The W370 and A37 couldn't be more different in physical presence and feel.

At just 100 x 57 x 26 mm and weighing a featherlight 179 grams, the W370 fits in any pocket - no problem. The built-in 7x zoom lens covers an impressive 34-238mm equivalent range, giving casual shooters lots of reach without fuss. Its compact design and light weight make it ideal for travelers or beginners who value simplicity and portability over control complexity.

In contrast, the A37 is a compact SLR shaped camera but significantly bigger: measuring 124 x 92 x 85 mm and tipping the scales at 506 grams (body only). It feels substantial in the hand, with a deep grip and heft that inspire confidence. This size enables a sturdier grip and room for more manual controls. The trade-off, of course, is that it’s not pocketable and demands a bag or dedicated carrying case.

The W370's control interface sticks to basics: limited buttons, no manual dials, and a fixed 3-inch screen. This simplicity appeals to point-and-shoot users but lacks the tactile feedback and direct control that more advanced photographers crave.

The A37 includes a tilting 2.6-inch screen (albeit with the same 230k dot resolution) and an EVF with 100% coverage and a sharp 1,440k dot resolution, vital for composing in bright light or tracking fast subjects. Manual dials, customizable buttons, and a flash hot shoe bolster its usability for more sophisticated shooting, bridging the gap between entry-level and enthusiast setups.

In all, ergonomics favor the A37 hands down for serious use, while the W370 wins on super-lightweight convenience. It’s a classic size-versus-control tradeoff.

Sensor and Image Quality: From Small Sensor Snapshots to APS-C Potential

Few decisions affect image quality more fundamentally than the sensor. The W370 uses a conventional 1/2.3-inch CCD sensor measuring just 6.17 by 4.55 mm (28.07 mm²), outputting 14 megapixels. Meanwhile, the A37 sports a much larger APS-C CMOS sensor (23.5 x 15.6 mm, 366.6 mm²) with 16 megapixels. This difference explains much about the cameras' capabilities.

The W370’s tiny sensor restricts dynamic range and low-light performance. Detail retention in shadows and highlights is limited; noise rises quickly beyond ISO 400. Color depth and gradation, while acceptable for snapshots, don’t deliver the subtlety serious photographers expect. The built-in anti-aliasing filter slightly softens images but reduces moiré artifacts.

In contrast, the A37’s APS-C sensor captures much finer detail with less noise at higher ISOs. Its larger photosites allow cleaner light gathering, improved dynamic range (nearly twice the stops of the W370), and more vibrant, nuanced colors. Sony’s CMOS tech paired with sensor-based stabilization enhances image quality in challenging lighting.

This considerable sensor advantage translates into professional-grade JPEGs straight out of camera and full RAW format support for extensive post-processing - a big win for serious workflow integration. The W370 doesn’t offer RAW, limiting post-production flexibility.

Bottom line: the A37’s sensor technology outclasses the W370 by a wide margin, meeting demands from portraits through landscapes and low-light shooting.

Autofocus and Shooting Performance: Precision Versus Simplicity

Autofocus (AF) separates casual shooters from serious photographers in real-world conditions like sports or wildlife photography.

The W370 has a contrast-detection AF system with 9 points, which suffices for static subjects in good light. However, it’s slow and hunts in low contrast or action scenarios. Continuous AF and tracking are not supported. The camera’s maximum continuous shooting rate is 2 frames per second, which hardly qualifies it for fast-paced photography.

The A37, however, employs Sony’s translucent mirror technology with a hybrid AF setup, combining phase detection (15 points, including 3 cross-type) and contrast detection. This enables quicker, more accurate focusing, especially with moving targets. It also supports continuous AF and can shoot bursts at 6 fps - a significant advantage for sports, wildlife, and candid street photography.

Face detection is available on both, but the A37 adds eye detection support, increasing hit rates for portraits. Low-light autofocus performs much better on the A37, thanks to its robust sensor and AF system.

Collectively, these specs make the A37 the clear choice for users prioritizing action and reliable focus. The W370 is best reserved for relaxed, casual shooting where fast focus isn’t mission critical.

Exploring Photography Genres: Which Camera Excels Where?

Our cameras find their strengths and shortcomings illuminated when applying them to typical photographic categories. Here's a breakdown across popular genres:

Portrait Photography

• Sony W370: Limited manual control and modest sensor size hamper skin tone rendition and bokeh quality. DOF control is constrained by the fixed lens’s max aperture of f/3.6–5.6 and small sensor. Eye detection autofocus is absent, so sharp focus on eyes is a challenge.
• Sony A37: Larger APS-C sensor and compatibility with fast primes (like f/1.8 or f/2.8 lenses) deliver better skin tone nuance, texture, and creamy backgrounds. Eye detection boosts portrait sharpness. Manual exposure modes enable elegant lighting control.

Landscape Photography

• Sony W370: The small sensor provides moderate resolution (14MP), sufficient for casual prints or online sharing. Dynamic range and noise control challenges limit capturing fine shadow detail on high contrast scenes. Weather sealing is absent.
• Sony A37: 16MP APS-C sensor presents excellent resolution and wide dynamic range for rich landscapes. Manual controls allow exposure bracketing and custom white balance for precise rendering. No weather sealing limits harsh conditions, but build quality is robust enough for moderate outdoor use.
