The A6400 employs a hybrid AF system combining 425 phase-detection points with contrast-detection, covering almost the entire frame, and capable of:

• Real-time Eye AF for humans and animals to keep critical focus sharp in portraits and wildlife
• Continuous AF tracking at 11 fps burst rates with precise subject locking
• Touchscreen AF point selection and focus magnification aids

From sports and wildlife to street and portraiture, the A6400’s AF system provides professional-grade speed and accuracy, vital for capturing fleeting moments without frustration.

Sony TX10 Autofocus Limitations

The TX10 has a much simpler system with 9 contrast-detection points and no phase-detection, lacking advanced face or eye detection. It can’t track moving subjects effectively and focuses moderately well on central subjects under good lighting.

For casual snapshots, this suffices, but it’s unsuitable for demanding action or wildlife photography where performance reliability matters.

Body Construction and Durability: Weather-Sealing vs Rugged Compact

Physical durability approaches differ markedly between these two. The A6400 is built with a magnesium alloy chassis and some weather sealing, protecting against light moisture and dust but not designed for immersion.

The TX10, however, targets the adventurous photographer with its fully waterproof, dustproof, shockproof, and freezeproof construction - uncommon in other compacts or mirrorless models.

This ruggedness makes the TX10 a great choice for poolside, beach, hiking, or winter travel photography where environmental hazards abound, albeit without the image quality advances of the A6400.

Viewing and Interface: Electronic Viewfinder vs LCD Only

The A6400 boasts a 2.36M-dot electronic viewfinder (EVF) with 0.7x magnification and 100% coverage, critical for accurate composition in bright outdoor conditions and demanding manual focus adjustments.

Diverse viewfinder assist modes - like focus peaking and zebra patterns - elevate technical precision.

Conversely, the TX10 lacks a viewfinder entirely, relying solely on its 3-inch LCD which is bright but less effective in direct sunlight or fast-action framing.

The presence or absence of an EVF will weigh heavily in professional workflows and certain types of on-location shooting.
