I have been using the mirror lockup feature to reduce vibrations when shooting landscapes with my Canon 5D Mk IV, it has been suggested to me that triggering the cameras shutter when in live view mode would be a better option for stills. It would mean one less shutter press (via remote cord) per image, which would be an advantage when capturing landscapes with moving elements like waves. Are there any disadvantages in using this method other than obviously not being able to see through the viewfinder and increased battery usage ?
