Sony A6600 vs Sony H20: In-Depth Comparison to Guide Your Next Camera Buy

When choosing a camera, the spectrum from compact point-and-shoots to advanced mirrorless systems is vast. Today, we zero in on two Sony offerings at very different points on that spectrum: the Sony Alpha a6600, a professional-grade APS-C mirrorless camera introduced in 2019, and the Sony Cyber-shot DSC-H20, a budget-friendly compact zoom from 2009. This comparison will distill 15 years of my hands-on camera testing experience into clear insights, helping you decide which camera suits your photographic ambitions and shooting styles.

First Impressions: Size, Ergonomics, and Build

Right from the start, you notice a fundamental difference in the physical design and feel of the two cameras.

The Sony A6600 presents a sturdy, rangefinder-style mirrorless body with a comfortable grip and robust weather sealing for real-world adventures. It measures 120x67x69 mm and weighs 503 grams - substantial but still pocketable in a large jacket pocket, especially when compared to DSLRs. Meanwhile, the compact Sony H20 weighs just 250 grams and is smaller still (107x69x47mm), making it extremely portable, even for everyday carry.

Ergonomic Overview:

• A6600: Excellent ergonomics for prolonged handheld use. Deep grip, well-spaced buttons, and customizable controls cater to fast shooting and precise adjustments.
• H20: Simplified control layout with mostly automatic modes, aimed at casual users. It lacks a viewfinder and advanced button customization, limiting tactile control.

While the H20’s compactness may appeal to casual shooters and travelers, the A6600’s more substantial size supports complex workflows and higher performance demands.

Design and Controls: Tailored for Different Users

Looking closer at the top controls helps highlight the practical usability of each camera in the field.

The Sony A6600’s top plate features dedicated dials for shutter speed, exposure compensation, and ISO, plus a mode dial with everything from automatic to fully manual exposure modes. The exposure compensation dial is a particular boon for photographers who want quick creative control without diving into menus.

On the other hand, the Sony H20 has a much simpler control scheme, including a mode dial focused on scene selections, a zoom rocker, and limited exposure adjustment options. It’s designed to get the shot done with minimal fuss but offers little room for manual creativity.

Sensor Technology and Image Quality

The heart of any camera lies in its sensor and processor, and here the differences between these two cameras become even more striking.

Sony A6600’s APS-C Sensor Technology:

• Sensor Size: 23.5 x 15.6 mm APS-C CMOS sensor (366.6 mm² surface area)
• Resolution: 24 MP (6000x4000 max)
• Processor: Bionz X engine for advanced image processing and noise reduction
• ISO Range: 100-32,000 (expandable to 102,400)
• DXO Mark Score: Overall 82, color depth 23.8 bits, dynamic range 13.4 EV, low-light ISO 1497

The large APS-C sensor on the A6600 provides excellent depth of field control, high resolution for pixel-level detail, and superior high-ISO performance. It’s well suited to demanding professional and enthusiast use cases, from portraits to landscapes.

Sony H20’s Compact Sensor:

• Sensor Size: 1/2.3" CCD sensor (6.17 x 4.55 mm, 28.07 mm²)
• Resolution: 10 MP (3648x2736 max)
• ISO Range: 100-3200
• DXO Tests: Not tested (typical for its sensor type and era)

The H20’s small sensor limits overall image quality. Expect noticeable noise and less dynamic range, particularly in low light or high contrast scenes. Its CCD sensor, now largely supplanted by CMOS sensors, offers decent color reproduction but cannot compete with the A6600’s imaging pipeline.

What This Means in Practice

• The A6600 captures crisp, detailed images with rich colors and clean shadows/highlights. Its sensor size also enables smoother, more pleasing bokeh in portraits.
• The H20 works well in bright light and for casual snapshots but struggles in dim settings and offers limited creative control over depth of field.

Rear Interface and User Experience

Intuitive, responsive controls on the back of the camera enable efficient, stress-free shooting.

A6600:

• 3” tilting LCD screen with 922k-dot resolution
• Touchscreen functionality for intuitive focus point selection and menu navigation
• High-resolution electronic viewfinder (2.36 million dots) covering 100% field
• Touchpad AF option in EVF for seamless focus adjustments

H20:

• Fixed 3” LCD screen with only 230k-dot resolution
• No touchscreen, no EVF - framing must be done with the LCD
• Brightness and angle options are limited

Practical photography benefits include the A6600’s EVF, essential for shooting in bright light or fast-moving scenarios where LCD glare could spoil framing and focus. Meanwhile, the H20 works best in well-lit environments where you can clearly see the LCD.

Autofocus and Speed Performance

For capturing decisive moments, autofocus accuracy and continuous shooting speed are critical.

The A6600 excels in fast-paced photography. Its sophisticated hybrid AF system locks on quickly and tracks moving subjects smoothly, including specialized eye autofocus that is game-changing for portraits and wildlife. The ability to shoot at 11 frames per second with continuous autofocus makes it an excellent sports or action camera.

In contrast, the H20’s AF system is limited by older technology and fewer focus points, making it better suited for static subjects and casual photography.
