![]() This 'Hybrid AF' is supposed to result in speedier AF, supporting the camera's ability to shoot at 5 fps with continuous autofocus. The a7 uses a 24.3 megapixel CMOS sensor with a low-pass filter and on-chip phase detection. Wi-Fi with NFC capability and downloadable apps. ![]() Full HD video recording at 1080/60p and 24p uncompressed HDMI output.3-inch tilting LCD with 1.23 million dots (640x480, RGBW).Hybrid AF system with 25 contrast-detect and 117 phase-detect points.E-mount with support for FE, E, and A-mount lenses (with adapter).24.3 megapixel full-frame CMOS sensor with OLPF.If you have A-mount lenses laying around, those too will work, as long as you pick up either of Sony's full-frame-ready adapters (the LA-EA3 or LA-EA4). Existing E-mount lenses will work, though the image will (necessarily) be cropped. Five lenses were announced to start with (listed below), with ten more promised by 2015. Both cameras use Sony's latest Bionz X processor and also have XGA electronic viewfinders, tilting LCDs, Wi-Fi, and weatherproof bodies that resemble that of the Olympus E-M1.Īs you'd expect, Sony had to come up with new lenses to take advantage of the full-frame sensors, and they'll be known as 'FE-series'. The a7 is also capable of electronic first curtain mode, which allows for a quieter shutter, and reduces the potential for 'shutter shock' vibration this is absent from the A7R. The a7 uses a Hybrid AF system (with on-chip phase detection) similar to the one found on the NEX-6, while the a7R has traditional contrast detection. The a7 features a full-frame 24 megapixel CMOS, while the a7R has a 36 megapixel CMOS sensor with no optical low-pass filter. The a7 and a7R are identical in terms of physical design, with the main differences being the sensor and autofocus system. Being mirrorless, the a7 would have otherwise likely been prefixed with the letters NEX. In addition, Sony is also unifying the Alpha and NEX brands, so all future interchangeable lens cameras will now fall under the Alpha umbrella. In other words, the Alpha 7s are much smaller than their full-frame interchangeable lens peers (such as Nikon's D610 and the Canon EOS 6D), an achievement made possible primarily because they're not SLRs. The company has managed to create full-frame cameras which are about the same size as the Olympus OM-D E-M1. Its latest products - the Alpha 7 and Alpha 7R - may be the most exciting products to come out of the Sony labs in some time. From SLRs with dual autofocus systems and 'Translucent' Mirror Technology to its NEX mirrorless line-up, Sony has gone down virtually every avenue in digital imaging. If there's one thing that you can say about Sony's digital camera business, it's that they've experimented with many different concepts. ![]()
