These cameras couldn’t be more different under the hood or in their intended use - one is a compact small sensor superzoom aimed at casual shooters craving versatility, while the other is a mirrorless powerhouse designed for advanced users seeking speed, image quality, and expandability. This comparison will break down everything from image quality to ergonomics, autofocus systems to video capabilities and more, sprinkling in insights rooted in my personal hands-on testing experience.

Whether you’re a traveler, portrait photographer, wildlife enthusiast, or just someone looking for a reliable everyday camera, by the end you’ll understand which of these two cameras fits your creative workflow best.

Getting Familiar: A Snapshot of Both Cameras' Design and Usability

Physically and conceptually, the Canon SX170 IS and Sony A6000 inhabit very distinct realms.

The Canon SX170 IS is a compact superzoom with a fixed 28-448mm-equivalent lens - making it a tempting all-in-one option ideal for casual shooting or travel without swapping lenses. It weighs just 251 grams and measures 108x71x44 mm, fitting snugly in a jacket pocket or handbag. However, it opts for a simpler control set and no viewfinder, leaning towards ease-of-use over serious manual control.

The Sony A6000, meanwhile, is a rangefinder-style mirrorless camera with an APS-C sensor and interchangeable lens mount. It’s more substantial at 344 grams and 120x67x45 mm, but impresses with intuitive, customizable controls, an EVF, and a tilting LCD. It invites more engagement from photographers who want manual exposure, advanced autofocus, and professional-grade image files.

In my testing, the Canon feels more like a capable point-and-shoot with zoom flexibility, excellent for spontaneous shooting but limited when it comes to fine-grained control. The Sony A6000, by contrast, encourages creativity and experimentation but demands at least some familiarity with advanced photography concepts.

Sensor Technology and Image Quality: The Heart of the Matter

One of the most profound differences between these cameras lies in sensor technology and image output.

The Canon SX170 IS features a 1/2.3-inch CCD sensor with a resolution of 16 megapixels, delivering images at 4608 x 3456 pixels. While decent for casual snapshots and acceptable prints, this sensor’s physical area of just over 28 square millimeters limits dynamic range and low-light performance. Noise becomes apparent beyond ISO 400, and color depth is understandably modest.

The Sony A6000 sports an APS-C-size CMOS sensor (23.5 x 15.6 mm), considerably larger at a hefty 366.6 square millimeters and boasting 24 megapixels at 6000 x 4000 resolution. This translates into more detail retention, superior dynamic range, and a remarkable ability to maintain color fidelity and low noise even at high ISO values of 3200 and above. The A6000 also supports RAW, which unlocks substantial post-processing flexibility.

In practical terms, the Canon is adequate for Instagram-worthy travel shots or family events in daylight. But if you prioritize pixel-peeping landscapes, night astrophotography, or critical portrait retouching, the Sony’s sensor has a clear advantage.

Autofocus and Burst Performance: Capturing the Moment

From fleeting wildlife encounters to fast-paced sports, autofocus and continuous shooting performance can make or break a shot.

The Canon SX170 IS utilizes a contrast-detection autofocus system with face detection and a modest tracking capability, featuring single AF mode but no continuous AF during bursts. It offers only 1 fps burst shooting, which is slow by modern standards. Focusing speed can be sluggish, especially in low light, and the number of AF points is minimal with no phase-detection hybrid.

On the Sony A6000, you get a much more advanced hybrid AF system combining 179 phase-detection points and 25 contrast-detection points, providing rapid, accurate locking even on erratically moving subjects. The A6000 can shoot bursts at an impressive 11 fps with continuous AF, a boon for wildlife and sports photography. Face detection is robust, and although it lacks animal-eye AF, the tracking capacity is quite capable in real-world tests.

For my wildlife fieldwork and fast sports shooting, the Sony’s AF system delivered a consistently higher keeper rate. The Canon’s sluggish single AF made following moving targets frustrating.

Build, Weather Resistance, and Ergonomics: Handling and Durability

Both cameras are entry to mid-level constructs without weather sealing, so caution is needed shooting in rainy or dusty conditions.

The Canon SX170 IS is plastic-bodied but lightweight and compact, mitigating fatigue during long hikes or travel days. Its ergonomics are modest: fixed rear LCD with 230k-dot resolution, no touchscreen, and minimal control dials, leaning heavily on preset shooting modes. Lack of a viewfinder can lead to difficulty in bright sunlight.

The Sony A6000, though slightly heavier, feels more solid and thoughtfully designed with a pronounced grip. It features a 3” tilt-angle LCD with a sharp 922k-dot resolution and a sharp 1.44M-dot electronic viewfinder with 100% coverage. The control layout around the shutter button and dials is excellent for quick exposure adjustments, and customizable buttons add flexibility.

During extended shoots, the A6000’s ergonomic refinement reduces hand strain. The SX170’s simpler design suits casual users but limits comfort for serious shooting.

Lens Ecosystem and Compatibility: Expanding Creative Possibilities

The Canon SX170 IS sports a fixed superzoom lens with a focal range equivalent to 28–448mm (16x zoom) and a variable aperture of f/3.5–5.9. It impresses with a minimal macro focus distance of 1cm but cannot accept additional lenses or filters, limiting creative control.

For razor-sharp portraits or ultra-wide landscapes, you're limited to the built-in lens characteristics.

In contrast, the Sony A6000 uses the Sony E-mount lens system, boasting access to over 120 lenses across focal lengths and apertures from various manufacturers. From wide-aperture primes that create creamy bokeh perfect for portraits, to fast telephoto zooms suitable for wildlife and sports, this ecosystem provides adaptability for every photographic genre.

This flexibility meant in my studio portrait sessions or macro experiments, the A6000 excelled, simply by pairing it with optimized glass suited for the task.

Exposure Control, Image Stabilization, and User Interface

The Canon offers manual exposure modes including aperture and shutter priority along with full manual, but settings are adjusted via traditional menu navigation rather than dedicated controls. It includes optical image stabilization helpful at telephoto lengths.

Sony’s A6000 features comprehensive exposure options accessible via tactile dials, supported by a responsive interface that accelerates workflow. While it lacks in-body stabilization, many E-mount lenses compensate with optical IS, and the electronic viewfinder assists in composing perfectly sharp shots.
