Comment: Since I had problems with leveling shots, I turned on the gridlines option. I later decided to switch to the electronic level. However, after a few weeks, I found the level distracting and difficult to use. I switched back to the gridlines. I chose the 9-zone grid to minimize the distraction while still taking advantage of the grid lines.
