If you're a photographer that really, seriously has a need for shooting with a vertical grip for business purposes that involve you padding your bottom line and ensuring that you can keep making money, then you can disregard this article.
But I genuinely feel like most photographers don't do this. The vertical grip on a camera is the photographer's equivalent to the person who buys a Toyota Corolla just to put a body kit, spoiler, LEDs, and rims on it while rolling through a suburban neighborhood with music on that folks can hear for a block down. While this doesn't quite disturb the peace, it surely is just as obnoxious. . thephoblographer.com
