Capture almighty professional 24.3MP detail – a 24.3MP full-frame Exmor CMOS sensor delivers unbelievably high resolution, high sensitivity and low-noise image quality Product DescriptionSony ILCE7B Full Frame Compact System Camera Body (24.3 MP, 117 Points Hybrid AutoFocus, 3.0-inch Tiltable LCD, 5 fps, XGA OLED Tru-Finder) – Black.
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. 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. 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. The company has managed to create full-frame cameras which are about the same size as the Olympus OM-D E-M1. 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.
In addition, Sony is also unifying the Alpha and NEX brands, so all future interchangeable lens cameras will now fall under the Alpha umbrella. Being mirrorless, the a7 would have otherwise likely been prefixed with the letters NEX.
The a7 and a7R are identical in terms of physical design, with the main differences being the sensor and autofocus system. 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 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 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. 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.
As 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’. Five lenses were announced to start with (listed below), with ten more promised by 2015. Existing E-mount lenses will work, though the image will (necessarily) be cropped. 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).
Sony a7 key features
24.3 megapixel full-frame CMOS sensor with OLPF E-mount with support for FE, E, and A-mount lenses (with adapter) Bionz X image processor Hybrid AF system with 25 contrast-detect and 117 phase-detect points Weather-proof alloy and composite body Multi-Interface Shoe 3-inch tilting LCD with 1.23 million dots (640×480, RGBW) XGA (1024×768) electronic viewfinder Diffraction correction technology Full HD video recording at 1080/60p and 24p; uncompressed HDMI output Wi-Fi with NFC capability and downloadable apps
The a7 uses a 24.3 megapixel CMOS sensor with a low-pass filter and on-chip phase detection. This ‘Hybrid AF’ is supposed to result in speedier AF, supporting the camera’s ability to shoot at 5 fps with continuous autofocus. The more expensive a7R, on the other hand, has a 36 megapixel sensor with no optical low-pass filter and a more conventional contrast-detect AF system.
Both the a7 and a7R can record video at 1080/60p and 24p, with manual exposure control, headphone and mic ports, an audio meter, zebra pattern, XLR support (via adapter), and live, uncompressed HDMI output.
Bionz X Processor
The company’s latest processor, dubbed Bionz X for reasons that presumably made sense to someone, is considerably more powerful than the previous generation, allowing what the company says is more sophisticated processing.
Sony is being a little vague on specifics but is touting the new processor as offering ‘Detail Reproduction Technology’ which appears to be a more subtle and sophisticated sharpening system. The company promises less apparent emphasis on edges, giving a more convincing representation of fine detail’.
Another function promised by the Bionz X processor is ‘Diffraction Reduction’, in which the camera’s processing attempts to correct for the softness caused by diffraction as you stop a lens’ aperture down. This processing is presumably aperture-dependent and sounds similar to an element of Fujifilm’s Lens Modulation Optimization system (introduced on the X100S), suggesting it’s something we should expect to see become more common across brands in the coming months.
Finally, Sony says the Bionz X chip offers a more advanced version of its context-sensitive, ‘area-specific noise reduction’, which attempts to identify whether each area of an image represents smooth tone, textured detail or subject edges and apply different amounts of noise reduction accordingly. Later in the review, we’ll show you just how well this system works, and also the problems it can create. Box ContainsPower cord
