Choosing the right camera often feels like a balancing act between portability, image quality, versatility, and price. The Sony Cyber-shot DSC-HX80 and the Sony SLT-A77 target very different corners in the camera market, yet both have been favorites among Sony users for years. Having tested thousands of cameras myself, I’m here to guide you through a detailed, no-nonsense comparison of these two. Whether you’re a casual shooter or a seasoned professional, this side-by-side will help you make an informed choice grounded in real-world performance, usability, and value.

First Impressions: Size, Ergonomics, and Build Quality

At a glance, the Sony HX80 and A77 couldn’t be more different physically - and that difference immediately dictates their intended use.

• Sony HX80: Featherlight at 245g and compact (102x58x36mm), this mirrorless compact wears its superzoom capability on its sleeve with a fixed 24-720mm equivalent lens. Its small size and light weight make it an unbeatable travel companion.

• Sony A77: Built sturdy with a mid-size SLR body and substantial heft at 732g (143x104x81mm), the A77 feels like a professional tool. It boasts weather sealing to protect against dust and moisture, an advantage for outdoor and demanding conditions.

The distinct body types also reflect in ergonomics. The A77’s deeper grip and extensive physical controls provide much more tactile feedback and efficiency for extended shooting sessions. The HX80 favors simplicity with limited buttons and a tilting 3-inch screen for versatile low or high-angle shooting.

Controls and Interface

The HX80’s compact interface is straightforward but limited to basic exposure modes, no manual lens focus ring, and no touchscreen. Its electronic viewfinder offers 100% coverage but lacks detailed resolution specs.

By contrast, the A77 features a fully articulated 3-inch screen with 921k-dot resolution, an impressively sharp electronic viewfinder at 2359k dots with 100% coverage and 0.73x magnification. This optical-like EVF enhances composition accuracy, a hallmark of advanced DSLRs.

The A77 also boasts a top panel LCD display for quick exposure reference - a feature absent from the HX80. More buttons, dials, and customizable options on the A77 give photographers expert-level control.

Sensor Technology and Image Quality: Small Sensor vs APS-C Powerhouse

Sensor size is frequently the crucial factor impacting image quality. Here’s how the two compare in specifications and how that translates to what you’ll see in your photos:

• Sony HX80: Uses a 1/2.3” BSI-CMOS sensor measuring 6.17x4.55mm with 18 megapixels. While this sensor is typical for compact superzoom cameras - favoring portability and lens reach - it is limited in dynamic range, noise performance, and overall image quality, especially in low light.

• Sony A77: Packs an APS-C CMOS sensor sized at 23.5x15.6mm with 24 megapixels - approximately 13 times larger sensor area than HX80’s. APS-C sensors produce richer color depth (24-bit color depth vs smaller for HX80), wider dynamic range, and better noise resistance at high ISO levels.

In practical tests, the A77 impresses with crisp detail, excellent highlight/shadow retention, and pleasingly clean images even up to ISO 1600 or beyond. The HX80 suffices for daylight and casual shoots but struggles with noise and softness when light levels drop.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus can make or break shots in fast-moving situations or challenging compositions.

• Sony HX80: Employs contrast-detection AF with face detection and multi-area autofocus points. It can track subjects and handles continuous AF up to 10fps burst rate. However, the contrast detection system is inherently slower and less reliable in low light and for moving subjects compared to phase detection.

• Sony A77: Features a sophisticated hybrid phase-detection AF system with 19 focus points (11 cross-type), enabling quicker lock-on, precision, and better subject tracking, particularly important for wildlife and sports photography. The 12fps burst coupled with reliable autofocus tracking makes it a serious tool for action.

From my testing, the A77’s AF consistently outperforms the HX80 in speed and consistency - especially in demanding light or fast sessions.

Display and Viewfinder Experience

The HX80 offers a tiltable 3-inch 921k-dot LCD, great for creative angles, but lacks touchscreen or resolution finesse. Its EVF is serviceable but basic.

The A77’s fully articulated 3-inch screen shares the same resolution but adds that invaluable top-screen info display and a crystal-clear, large EVF that gives an edge to critical manual focusing or composition in bright conditions. This makes a distinct difference for professionals who need precision.

Lens System: Fixed Superzoom versus Interchangeable Power

• Sony HX80: Comes with an integrated 24–720mm (30x zoom) lens - tremendous reach for its class but with a slow aperture range of f/3.5–6.4. This limits performance in low light and depth of field control. No lens swaps mean versatility is limited to what this lens covers.

• Sony A77: Uses the Sony/Minolta Alpha mount with over 140 compatible lenses, including high-quality primes, macro options, fast zooms, and specialized glass. This opens boundless creative potential, allowing you to tailor your optics exactly to your needs - from shallow portrait bokeh to macro details or wildlife telephoto reach.

In my experience, the ability to swap lenses profoundly affects artistic freedom and technical quality. While the HX80 is easier to carry, it’s ultimately limiting in serious photography disciplines.
