The Vertax E20 from Pixel is a battery grip, which is especially developed for your Canon 5D Mark IV. You can insert one or two LP-E6(N) batteries into the battery grip, to power the 5D Mark IV with a single or double capacity. Next to that, the Vertax E20 offers multiple extra buttons, which contributes to an ergonomic operation. For example the Vertax E20 does have a focus/shutter button, main dial, multiple AF-buttons, multi controller, exposure lock and on/off button.
Usage Vertax E20
The Vertax E20 is a great accessory for your Canon 5D Mark IV, when you want an extended battery capacity, better grip and optimal operation while shooting vertical images. For an example, think about portrait photos.
Vertax E20 in practice
You can connect the Vertax E20 onto the bottom side of your camera, with the 1/4 inch screw thread and related turn knob. After that, you place the batteries into the Vertax E20 and turn the switch to 'on'. To protect your camera and battery grip, you can attach a neck strap to the mounting bracket (see optional accessories). When shooting vertical images, you now have access to extra buttons. This prevents you to turn your hand 90 degrees.
