Existing E-mount lenses will still physically fit, but as they're only designed for use with APS-C sensors, their image circles won't cover the entire frame properly (just like using Sony's DT lenses on full-frame Alpha mount cameras). While the a7R has an E-mount, you'll need to use Sony's new FE-series lenses to take advantage of its full-frame sensor. Later in the review, we'll show you just how well this system works, and also the problems it can create. 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.įinally, 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. The company promises less apparent emphasis on edges, giving a more convincing representation of fine detail'.Īnother 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. 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'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. It records 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. While the a7R is really focused on still image quality - due to its high resolution sensor without an AA filter - it's also quite adept at video recording.

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. Here's a quick summary of the differences between the a7 and a7R: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'. 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. 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 you can say about Sony's digital camera business, it's that they've experimented with many different concepts. If you're looking for our review of the Sony A7, please click here.
