    Is it worth all the hype?

    The timeless Alpha A7S III still shines with its standout features years after its release. Okay, it's not a budget buy, but for just under $3,500, you're getting cinema-quality visuals as silky as butter. Its dual-chip Bionz XR processor gives you speedy auto-focus, exposure, and top-notch video quality. Its impressive ISO range and 15-stops of dynamic range ensure crystal-clear footage.
