Sony’s new a7 and a7R digital cameras are claimed to be the world’s smallest full-frame interchangeable lens models.
The 7R features a 36.4 effective megapixel full-frame Exmor CMOS sensor – the highest resolution sensor in the history of Sony’s alpha line – with no optical low pass filter for added resolving power and increased image detail.
The alpha7 has an impressive 24.3 effective megapixel full-frame Exmor CMOS sensor and an innovative, fast Hybrid AF system.
Each camera is equipped with a new BIONZ X processor; fast AF capabilities; a clear, bright XGA OLED Tru-finder; full HD 60p video recording; Wi-Fi and NFC connection; as well as dust-and moisture- resistance.
Both cameras feature full customization and control. There are nine different customizable buttons and 46 assignable functions that can be adjusted based on shooting preferences, including fully customizable front and back dials, a rear control wheel and an exposure compensation dial.
Users can preview all changes to photographic settings in real-time on the high-contrast viewfinder or the high-resolution, tiltable, 3-inch LCD screen.
The new cameras share a new processor that accurately reproduces details in textures in real-time via extra high-speed processing capabilities, says Sony, and allows for exceptional low noise performance in all types of lighting conditions. Additionally, the processor, combined with the advanced, high resolution sensors, allows both cameras to shoot pro-quality Full HD video (AVCHD progressive, 1920x1080p at 60p) with richly detailed colours and ultra-low noise.
Clear Image Zoom has been enhanced for video recording as well, allowing for powerful close-up shots without sacrificing pixel count. Other pro-style movie features include an audio recording level control and display plus a “live” HDMI output for passing through video to an external monitor or recording device.
The new cameras both have on-board Wi-Fi and NFC capabilities for instant image sharing and transfer to compatible smartphones and tablets.
The two models can access Sony’s platform of PlayMemories Camera Apps, allowing users to add new effects, filters, utilities and more. This platform includes a new ‘Multiple Exposure’ app, which automatically combines sequential exposures into one creative shot, and ‘Smart Remote Control’, which allows for direct control of exposure and shutter speed from a connected smartphone.
The new alpha7 and 7R cameras each have a tough, magnesium alloy build and are dust and moisture resistant.
The a7R is designed for professional photographers and highly advanced enthusiasts, says Sony.
It features a new Fast Intelligent AF technology that delivers what Sony calls “blazingly quick,” accurate autofocus. Additionally, there are a total of three selectable sizes for the Flexible Spot AF frame, minimizing the risk of accidentally focusing on the wrong target.
Sony says the a7 is an entry point into full-frame photography.
The new camera has a Fast Hybrid AF system that combines phase- and contrast-detect AF methods to ensure speedy, accurate autofocus. It can also shoot at up to 5 fps continuously with non-stop AF tracking.
Among the accessories being offered for the new cameras is a new vertical grip that offers greater comfort during vertical shooting and can accommodate two separate NP-FW50 batteries for extended battery life and shooting time.
A new compact external battery charger quickly charges batteries, and an off-camera shoe allows the use of external flashes in off-camera wired applications.
The Sony a7R and a7 cameras will be available in late November. The 7R will be offered as a body-only for about $2300. The alpha 7 will be offered with a 28-70 mm f/3.5–5.6 lens for about $2000. It will also be offered as a body-only for about $1700.
