Unveiled: The New Sony a77II DSLR Camera
Sony has just announced the upgraded replacement for their Alpha SLT-A77 DSLR and is calling it the Sony a77II DSLR Camera. The new Sony camera is available as a body only and also as a kit with a 16-50mm f/2.8 DT lens. The a77II takes its place just behind the flagship a99 as a high-performance, fast-focusing A-mount APS-C DSLR and has improved upon the performance of its predecessor, thanks to the inclusion of the BIONZ X image processor and the new wide-coverage phase detection autofocus system with 79 AF points, including 15 cross-type points.
"The BIONZ X image processor, which enables faster overall performance and improved video capability, also enhances the reproduction of image details with sharp delineations and less noise."
Featuring a 24.3MP Exmor CMOS sensor, image quality and color reproduction on the a77II are impeccable even at high ISO sensitivities, which run from 100-25600 and are expandable to ISO 51200. The gapless sensor design and optimized on-chip lens positioning increase the light-collecting capability of the sensor, particularly at the edges and corners of the frame. The BIONZ X image processor, which enables faster overall performance and improved video capability, also enhances the reproduction of image details with sharp delineations and less noise. Integrated diffraction-reducing technology maximizes the optical performance of lenses, especially when shooting with small aperture settings. In addition to the above noted advancements, the a77II has built-in Wi-Fi connectivity with NFC for wireless image transfer and remote camera control via smart devices.
Utilizing Sony’s innovative Translucent Mirror Technology and a new AF sensor with wide and dense point coverage, AF tracking performance is optimized, making the a77II an ideal camera for capturing fast-moving subjects. Improvements in the autofocus system also include the Expanded Flexible Spot that employs the 8 AF points around the select AF point to better maintain tracking focus and a more advanced Lock-on AF. The a77II realizes impressive focusing accuracy, even when a large-aperture lens is mounted, thanks to the f/2.8 AF point, placed horizontally in the center of the AF sensor. Low-light focus accuracy has been improved and other new autofocus features include Eye AF, AF Range Control, 5-Step Tracking Adjustment, and Balance Priority setting. Furthermore, the Translucent Mirror, teamed with the new BIONZ X processor, allows full-resolution continuous shooting at 12 fps and for up to 60 frames in Fine quality JPEG.
The a77II provides both an LCD monitor and the OLED Tru-Finder Electronic Viewfinder for live view image composition and playback. The 2,359k-dot Tru-Finder EVF offers wide-angle, high-contrast, and high-resolution viewing with 100% frame coverage and a 27mm eyepoint. Real-time effects of camera adjustments make shooting through the EVF a more intuitive experience; depth of field, exposure compensation and all 13 picture effects can be seen in the EVF before the image has been shot. The 3.0" 1,229k-dot 3-way tiltable LCD screen enables clear image view with a rotating, tilting capability for shooting from any angle, including up and down tilt when shooting vertically. White Magic technology improves viewing under direct sunlight.
SteadyShot INSIDE image stabilization is incorporated into the camera body so that every lens used with the a77II is provided with stabilization to reduce blur when shooting at longer shutter speeds. Also, a built-in pop-up flash with a guide number of 39' and wireless trigger capability is supported as is the Sony Multi-Interface Shoe for attaching an external flash or any number of accessories for shooting video.
The BIONZ X processor also serves to improve the video capability of the a77II. Full HD 1080 at 60p and 24p is supported and new features include 3-step AF Tracking on moving subjects, a zebra function for accurate exposure, and controllable metered audio levels for both the built-in and optional external microphones. Program, Shutter Priority, Aperture Priority and Manual exposure control are supported and recording in both the AVCHD and MP4 codecs are possible. You also have the option of capturing uncompressed HD video to an optional external recorder for super high bit-rate via the clean HDMI output.
Built-in Wi-Fi with NFC is new to the a77II, and enables immediate wireless transfer of images to your smartphone, tablet, or even Wi-Fi-enabled TV when the free PlayMemories Mobile App Version 3.0 is installed on the mobile device. NFC allows linking to an Android device with just a simple touch between camera and device and Smart Remote Control lets you use your smart device as a remote control for camera operation. Via Wi-Fi or the camera’s HDMI output, still images can be transferred to 4K-compatible televisions for the utmost in high-resolution viewing.
Physically, the a77II has been made more durable and provided with enhanced weather-resistant features. A strong, yet lightweight magnesium-alloy body is complemented by double-layered dust and moisture seals around the main buttons, dials, ports, and doors. The shutter unit has been tested to endure up to 150,000 actuations. Further design refinements have made the grip more comfortable and provided the buttons with distinct shapes for tactile recognition. Eleven customizable buttons (10 on the camera body and one on select lenses) enable control over 53 assignable functions, which is a major increase over the three customizable buttons on the a77. Furthermore, the Memory Recall mode, which is located on the mode dial, can recall up to three sets of camera adjustments, and the User Interface includes the customizable Quick Navi Pro and Fn button for fast access to oft-used functions.
The Sony a77II DSLR camera is available as a body only but also with 16-50mm f/2.8 DT lens, which provides a versatile set of focal lengths equivalent to 24-75mm in the 35mm/full-frame format. A fast f/2.8 maximum aperture is effective in low light and offers shallow depth of field. Extra-low dispersion glass and aspherical lens elements minimize aberrations and lend themselves to sharp, high-contrast imaging. The SSM Super Sonic Wave Motor provides fast, smooth, and silent autofocus, which is the perfect complement for the new AF system on the a77II.
