Sensor technology has improved remarkably in recent years, especially in compact cameras. The Canon SX400 IS and SX620 HS share the same 1/2.3-inch sensor size but differ in sensor type and resolution.

Technical Explanation:
The SX400 IS uses a traditional CCD sensor. CCDs were the workhorse sensors of the previous decade, valued for color accuracy but limited in speed and high-ISO performance. In contrast, the SX620 HS features a more modern Backside-Illuminated CMOS (BSI-CMOS) sensor, allowing for better light gathering, higher ISO capabilities, and faster readout speeds.

In practical terms, you can expect the SX620 HS to outperform the SX400 IS in dynamic range - the ability to retain details in shadows and highlights - and in low-light image quality, thanks to its higher sensitivity and modern sensor.

Display and Interface: How You Interact Matters

Both cameras feature a 3-inch fixed LCD screen - a standard for compact superzooms - yet differ in resolution and interface sophistication.

The SX620 HS’s higher resolution screen offers a clearer and more detailed live view and image playback experience, crucial when reviewing focus accuracy or exposure in the field. Neither camera offers touchscreen controls, which is common in this compact superzoom class but something worth noting if you favor intuitive menu navigation.

Lens, Zoom, and Optical Performance: Reaching Further

Superzoom cameras live and die by their zoom optics. Both cameras offer long zoom ranges but with distinct focal lengths and max apertures.

The SX400 IS offers an impressive 30x zoom, extending to a super-telephoto reach of 720mm equivalent, whereas the SX620 HS maxes out at 625mm (25x zoom). The wider zoom range on the SX400 IS gives it an advantage for wildlife and sports scenarios where reach is vital.

The SX620 HS boasts a slightly wider maximum aperture at the wide end (f/3.2 vs. f/3.4), which can help in low-light wide-angle conditions. However, its aperture narrows faster toward the telephoto end (f/6.6) compared to the SX400 IS (f/5.8), potentially resulting in slower shutter speeds and more reliance on ISO or stabilization at full zoom.

The macro focus distance is particularly impressive on the SX620 HS - as close as 1cm - allowing for tighter close-ups with better detail. The SX400 IS lacks a dedicated macro capability.

Autofocus and Shooting Speed: Capturing the Moment

Quick and accurate autofocus and shooting speed significantly influence your ability to capture fleeting moments.

While both cameras rely on contrast-detection autofocus - with no phase detection - the SX620 HS adds “selective” AF point mode, offering more precise focus targeting. Also, its continuous shooting speed of 2.5 frames per second (fps) outpaces the SX400’s slow 1 fps, making the SX620 better for basic action or street photography, though neither excels at fast sports capture.

Face detection is included on both models, assisting portraiture and candid street shots.

Video Capabilities: Moving Images and Sound

Video has become a critical part of modern cameras, even compact ones. Here’s how these two Canon superzooms stack up.

The SX620 HS clearly steps up the game with full HD video at 30fps, compared to the SX400’s max HD at 720p and 25fps. While neither supports external microphones, the inclusion of HDMI output on the SX620 can be handy for monitoring or external recording with compatible devices, an important feature for vloggers and amateur filmmakers.

Battery Life and Connectivity: Staying Powered and Linked

Battery endurance and connectivity options influence your shooting day length and post-processing.

The SX620 HS’s more advanced DIGIC 4+ processor and efficient sensor allow for nearly 50% longer battery life, a notable advantage for travel and daily shooting.
