Sony on Monday at Photokina 2016 introduced the Alpha a99 II, its first flagship-class, full-frame interchangeable lens camera in four years. The wait seems to be well worth it as the a99 II is loaded to the brim with pro-level features.

The a99 II comes loaded with a 42.4-megapixel Exmor R CMOS full-frame sensor with an ISO range of 100 to 25,600 (expandable to ISO 50 - 102,400). If you're familiar with Sony shooters, you'll recognize this sensor as the same one found in the company's excellent a7R II mirrorless camera.

There's also a new front-end LSI that works with the sensor and BIONZ X image processing engine to enable continuous shooting at up to 12 frames per second. 4K video recording (3,840 x 2,160 @ 30 frames per second / 100Mbps) comes standard.

Elsewhere, the camera features a hybrid autofocus system using 3D Focus technology which affords 79 dedicated phase detection points along with 399 focal plane phase detection points - both of which work concurrently at all times.

Another carryover from the a7 II line is the 5-axis image stabilization system (pitch, yaw, horizontal motion, vertical motion and roll motions) that'll help keep the camera steady in low-light scenes.

Sony says the a99 II is a bit more refined than the original, now eight percent smaller with a new grip, magnesium alloy body and dual SD card slots. The button, dials and media jack cover are all sealed to provide a shield against dust and moisture although Sony doesn't guarantee it'll keep out 100 percent of the elements.

Sony's a99 II is slated to arrive in November priced at $3,199 (body only).
