Sony SLT-A77 II Avis | 108 Données comparées

The Sony Alpha SLT-A77 II is a robust Translucent Mirror camera characterized by a 79-point autofocus system, 12 fps burst shooting, and a fully articulating LCD screen. Key pros include solid weather-sealed construction, excellent RAW dynamic range, and effective tracking for video, making it suitable for action photography. Conversely, the camera suffers from inconsistent "Lock-on AF" tracking, heavy image noise at high ISO, and a restrictive 12 fps mode that locks exposure and freezes camera functions during buffer clearing. Additional cons noted by DPReview include a lack of a headphone jack and a mushy rear joystick. DPReview

The Sony Alpha A77 II is a high-speed, 24.3-megapixel APS-C Translucent Single-Lens (SLT) camera designed for action photography, featuring a 79-point autofocus system and 12fps continuous shooting. It offers excellent color reproduction, superior sharpness, a robust weather-sealed body, and a highly versatile 3-way tilting LCD. According to ePHOTOzine, key cons include lower low-light performance due to higher noise at high ISOs, significantly shorter battery life compared to traditional DSLRs, and lack of a headphone socket. Despite these issues, the camera is highly recommended for its advanced tracking, solid build quality, and strong performance for enthusiasts.

The Sony A77 II demonstrates significant image quality improvements over its predecessor, primarily driven by its 24.3-megapixel APS-C sensor and updated BIONZ X image processor. At base ISO (ISO 100), the camera captures outstanding, crisp, fine detail and excellent contrast, particularly outperforming the original A77 and the Canon 70D in mosaic and fabric test shots. Print quality at lower sensitivities is highly impressive, yielding sharp 36 x 48-inch prints at ISO 50/100 and clean 24 x 36-inch prints at ISO 400 with virtually no visible noise. Even at mid-range sensitivities like ISO 1600, the processor maintains vibrant colors and delivers a very usable 16 x 20-inch print. Pros and Cons Pros: Outstanding fine detail and high-contrast sharpness at base ISO. Highly effective noise reduction in shadow regions. Exceptionally large, gallery-quality low-ISO print options. Cons: Aggressive, heavy-handed default high-ISO noise reduction processing. Softness and loss of fine, low-contrast details at ISO 3200 and above. Competitors like the Fujifilm X-T1 and Nikon D7100 resolve fine fabric textures better at higher ISOs. Unusable print quality at the maximum ISO of 25,600.

The Amateur Photographer review of the Sony Alpha 77 II identifies the camera as a highly capable, well-engineered tool for enthusiast action and wildlife photography, boasting a 24.3-million-pixel APS-C sensor and a 79-point phase-detection autofocus system. Key strengths include 12 frames per second continuous shooting, a robust weather-sealed magnesium alloy body, and a clear 2.3-million-dot EVF. However, the review notes drawbacks, particularly aggressive noise reduction at high ISOs, which sacrifices fine detail beyond ISO 6400, and a complex menu system. Additionally, the translucent mirror technology causes a 0.3EV light loss, and unlike its predecessor, this model lacks built-in GPS.

The Trusted Reviews assessment of the Sony Alpha A77 II highlights a robust 24.3-megapixel APS-C camera designed for outdoor, sports, and wildlife photography, featuring a 12fps burst mode and rapid subject tracking. Key advantages include a durable, weather-sealed magnesium alloy body, a highly versatile three-way tilting LCD, and strong, detailed image output. Conversely, the camera's drawbacks include a complex menu system, the removal of built-in GPS in favor of Wi-Fi/NFC, and significant image noise paired with aggressive noise reduction at settings above ISO 6400.

The Sony Alpha A77 Mark II earned a 90% score from What Digital Camera, which lauded it as a high-performance A-mount camera for enthusiasts. Key advantages include a rapid 12fps continuous burst mode with an improved buffer, a robust weather-sealed body, and a sophisticated 79-point AF system that offers extensive frame coverage. Conversely, the review notes that image quality at high ISO settings is slightly underwhelming, and the built-in GPS from the previous model was replaced with Wi-Fi. Despite the superb electronic viewfinder, user preference may still lean toward traditional optical viewfinders.

The TechRadar review of the Sony Alpha 77 Mark II highlights this enthusiast-level single lens translucent (SLT) camera as a highly capable upgrade over its predecessor, pairing a newly designed 24-megapixel Exmor sensor with a powerful Bionz X processor. Reviewer Angela Nicholson praises the camera’s standout strengths, particularly its excellent image quality that captures rich detail, alongside effective noise control even at high sensitivity settings. The camera's major highlight is its completely overhauled 79-point phase-detection autofocus system (including 15 cross-type points). This system delivers exceptionally fast, accurate tracking and robust performance in very low light conditions. Additionally, continuous shooting speeds peak at an impressive 12 frames per second with a vastly upgraded buffer capacity capable of capturing up to 25 RAW and JPEG files in a single burst. Despite these strong performance marks, the review identifies several distinct design and usability drawbacks. A primary ergonomic issue is the cumbersome articulating mechanism on the rear screen, which complicates swift handling. Furthermore, despite modern trends, the screen entirely lacks touch-screen functionality. From an operational standpoint, the reviewer notes that placing the 12fps...

Here is a summary of the DXOMARK sensor review for the Sony SLT Alpha 77 II camera: Review Summary The Sony SLT Alpha 77 II achieves an overall DxOMARK sensor score of 82, matching the performance of key rivals like the Pentax K-5 IIs, Nikon D3300, and Sony's own A6000. Geared toward sports and action photographers, the camera retains its predecessor's 24-megapixel APS-C CMOS sensor format and 12 fps continuous burst capability, but notably upgrades its buffer to handle up to 60 full-resolution JPEGs. Its standout features include a revamped, wide-area 79-point autofocus module (with 15 cross-type sensors) that supports continuous AF tracking. It also benefits from Translucent Mirror Technology, which allows live view tracking through either the upgraded 2.4 million-dot OLED viewfinder or the highly adjustable, three-hinge tilt/swivel rear LCD screen.

The What Digital Camera review awards the Sony Alpha A77 Mark II an overall score of 90%, highlighting its robust build, weather sealing, and a rapid 79-point autofocus system capable of 12fps shooting. The camera is particularly recommended for action and wildlife photography due to its extensive buffer and intuitive Quick Navi Pro interface. Conversely, the review identifies limitations in high ISO noise management, with the 24.3-megapixel sensor struggling slightly in low-light conditions compared to competitors. Despite this, the camera is lauded for delivering excellent value and strong performance, earning a recommendation for photography enthusiasts.

The Sony Alpha A77 II is a robust, magnesium alloy APS-C camera designed for budget-conscious action and sports photographers, standing out with a blistering 12 frames per second continuous RAW burst rate and a highly dense 79-point phase-detect autofocus system. It utilizes a unique SLT Translucent Mirror design and an excellent electronic viewfinder (EVF) that allows for real-time exposure adjustments, histogram tracking, and video recording directly through the eye-level finder. Image quality from its 24-megapixel sensor is highly detailed at low ISO levels and shows a noticeable improvement over its predecessor, offering superior dynamic range and flexibility for RAW-format post-processing. Additional highly regarded features include built-in sensor-shift image stabilization, weather-resistant seals, integrated Wi-Fi for instant smartphone sharing, and a responsive rear joystick for rapid focus point selection. Despite its impressive, pro-level specifications, the camera does have clear drawbacks. While its low-light RAW performance holds up slightly better than Canon equivalents when pushed, its default JPEG image quality at ISO 1600 and above falls short of competitors like the Nikon D7100 and Fujifilm X-T1, showing heavy-handed noise reduction and a loss...
