Sensor and Image Quality: A Gigantic Leap in Technology
The heart of any camera is the sensor, dictating image fidelity, dynamic range, noise performance, and resolution. Here the differences are profound, reflecting technological advancements over nearly a decade.
Sony A6400’s APS-C CMOS Sensor
The A6400 features a 24.2-megapixel APS-C sized CMOS sensor (23.5 x 15.6mm) - a large sensor format that yields excellent image quality with wide dynamic range and high sensitivity.
- Sensor resolution: 6000 x 4000 pixels delivering big, detailed files
- Dynamic range (DxOmark): 13.6 EV, excellent for preserving highlight and shadow details in landscapes and portraits
- Color depth (DxOmark): 24 bits, enabling rich and nuanced color gradations
- High ISO performance: Native up to ISO 32,000 with expanded ISO 102,400, suitable for low-light and night photography
This sensor’s size and quality potentiate landscape, portrait, wildlife, and professional work where image quality and post-processing latitude are critical.
Sony TX10’s 1/2.3” BSI-CMOS Sensor
The TX10’s sensor is a tiny 1/2.3 inch BSI-CMOS with 16 megapixels (4608 x 3456 pixels), considerably smaller in area (~28 mm²). While this is typical for ultra-compacts:
- Noise levels escalate rapidly beyond ISO 800
- Dynamic range is constrained, limiting shadow recovery
- Color depth and tonal subtlety are below APS-C class sensors
These constraints mean images often suffice for casual prints and social media, but won’t fulfill professional requirements for large prints or intricate editing.
In terms of raw shooting capability, the A6400’s sensor will outperform the TX10 in practically every photographic discipline demanding image fidelity.
Autofocus Systems: Precision and Speed for Every Moment
A sophisticated autofocus (AF) system can be a game-changer, especially in fast-paced or unpredictable shooting scenarios. Here, the A6400 again leads with state-of-the-art features.
Sony A6400 Autofocus Details
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.
Burst Rates and Shutter Speeds: Capturing the Decisive Moment
With 11fps maximum continuous shooting on the A6400 and shutter speeds maxing at 1/4000s, it competes with professional APS-C mirrorless peers, perfect for sports, wildlife, and street photography demanding fast capture.
The TX10 offers 10fps continuous shooting, an impressive feat for a compact of its class, but with a slower shutter speed ceiling at 1/1600s, limiting freezing extremely fast action or shooting wide aperture shots in bright light.
Lens Ecosystem and Flexibility
The A6400’s Sony E-mount compatibility unlocks 121 lenses ranging from primes to super-telephotos, macro to ultra-wide options. This enormous aftermarket support offers:
- Exceptional creative latitude across genres
- Optimized optics for sharpness and stabilization
- Professional-grade lenses with weather sealing and fast apertures
The TX10’s fixed lens (25-100mm equiv., F/3.5-4.6) is versatile for general photography but lacks interchangeable lens flexibility. Its macro mode extends to focus as close as 1cm, useful for casual macro shots.
Lens choice and expandability are major differentiators aligned with user goals - highly important for enthusiasts and professionals.
Video Capabilities: 4K on the A6400 vs Full HD on the TX10
Considerable divergence shows in video functionality:
- Sony A6400: 4K UHD 30p @ 100 Mbps in XAVC S format, with full manual video controls, microphone input (no headphone jack), and built-in image compensation. Lack of in-body stabilization can be offset by stabilized lenses or gimbals.
- Sony TX10: 1080p 60fps max, no 4K, limited manual control, no external microphone inputs.
For videographers, the A6400 is the clear choice delivering professional-grade quality, wide codecs, and adaptability.
