Pro DSLRs

摘要

What makes aDSLR "professional"? There aren't hard and fast rules, but several features set these cameras apart, like beefy alloy bodies, rubberized handgrips, and dependable shutters that can be fired hundreds of thousands of times without a hiccup. They also combine zippy, multipoint autofocus systems with the ability to fire upwards of 10 frames per second, meaning they can track and capture action in ways not possible with consumer models.
