There's been a bit of buzz about Sony's rumored Alpha A7 mirrorless camera models, and finally, the company revealed early on Wednesday what photography fans have been waiting for: its α7 and α7R digital cameras. It also surprised with a new RX10 zoom camera to its Cyber-shot line.

Sony claims its new mirrorless models, the Alpha 7 (pictured above) and Alpha 7R (for advanced photographers and professionals), are the world's smallest full-frame interchangeable-lens cameras.

Both cameras come a range of imaging features, including Sony's new BIONZ X processor, fast autofocus capabilities, an XGA OLED viewfinder, full HD 60p video recording as well as Wi-Fi and NFC connectivity. Both are made of magnesium alloy and built to withstand dust, moisture and tough weather conditions.

“With these new α7 camera systems, Sony has completely redefined the look and feel of a professional-grade digital camera,” Mike Kahn, director of the interchangeable lens camera business at Sony Electronics, said in a statement. “The α7 and α7R cameras are significantly smaller, lighter and more portable than any other full-frame interchange lens camera yet deliver image quality, power and performance that professionals and enthusiasts crave.”

The α7R model packs a 36.4-megapixel 35mm Exmor CMOS sensor, which is the highest resolution sensor in the Alpha lineup, and no optical low-pass filter. This aims to reduce picture noise and keep images clear.

Meanwhile, the Alpha 7 version has a 24.3-megapixel full-frame Exmor CMOS sensor, as well as a Fast Hybrid AF system that combines phase- and contrast-detect AF methods for quickly zeroing in on a target. It can shoot at up to five frames per second continuously with non-stop AF tracking, so users can capture moving objects without blurring the image.

Not surprisingly, the cameras are costly. The α7R camera will be priced at $2,300 for body only. The Alpha 7 will be offered with a 28-70mm f3.5–f5.6 full-frame lens (model SEL2870) for about $2,000 and available for body-only for $1,700. Both cameras will be available in December.

Sony also introduced a new product to its RX family. The RX10 comes with a 20.2 "effective" megapixel back-illuminated CMOS sensor and a 24-200mm (35mm equivalent) F2.8 Carl Zeiss Vario Sonnar T zoom lens. It takes both stills and full HD videos.

Just like the Alpha models, the RX10 features a BIONZ X processing engine and AF system. It will cost about $1,300 and go on sale in November.

Sony added five new full-frame e-mount lenses to its collection too, including mid-range zoom lenses from Sony and Carl Zeiss, two Zeiss Sonnar T TM prime lenses and a G LensTM telephoto zoom. Its interchangeable lens lineup now offers 21 different lenses.
