Don’t underestimate this part though. Whenever you put your eye to the viewfinder, your perception changes. Even if you only look at the live view, it’ll affect your stability on the bike. I actually find it easier to use my phone than an actual camera for the rolling shots.
From my experience, it’s quicker to frame the shot via the viewfinder than the LCD. Especially when out in bright (summer) conditions. I’ve tried both though and I still prefer the viewfinder.
