Sony Alpha a7 II Review

The Sony Alpha a7 II is an image-stabilized full frame mirrorless camera, the fourth release in Sony's a7 lineup and the follow up the original a7. It uses the same 24-megapixel sensor as its predecessor, and the same Bionz X processor as the rest of the a7 series. Improvements come in the form of 5-axis sensor-based image stabilization, improved AF performance and some overall design tweaks. The controls are laid out in similar fashion to the a7, though the grip, command dials and shutter have been completely redesigned.

Prepare to be impressed: Tamron 15-30 F2.8 vs. Nikon 14-24 F2.8

While we were at CP+ 2015 in Japan, we met with Tamron, and the company was kind enough to lend us their newly announced 15-30mm F2.8 Di VC USD. In Nikon mount, no less. It's a wide range for a full-frame zoom, made more impressive by the inclusion of vibration compensation (VC). With a price tag of $1200, Tamron is taking the Nikon 14-24 head-on, and so we decided to do the same: pit the two against one another in a shootout, which you can view here

Unlike the other two, the a7S is specially geared toward video and low-light shooters. It's capable of 1080/60p video with full-sensor readout and can turn out uncompressed 4K footage to an external recorder over HDMI. Read review

Sony Alpha 7S Review
500

The a7S is the third model in Sony's full-frame mirrorless lineup, a 12MP camera that puts as much emphasis on its movie capture capabilities as its still image prowess. While the a7S is a capable still shooter, Sony has emphasized that its real focus (no pun intended) is videography.
