Sony’s a7 and a7r full-frame mirrorless cameras were only so-so for video, but the a7s is an absolute killer. The only thing lacking at launch was a good selection of lenses to suit the needs of videographers. That is starting to change with the new 28-135mm f/4 OSS.
Sony’s full-frame mirrorless duo, the A7 and A7r, are about to become just a bit more capable with the latest firmware released today. Improvements include faster autofocus, improved startup time, and a vaguely stated ‘improved image quality.’
