There is no doubt that my favorite, and most used camera control is the exposure dial. I love being able to use my thumb to adjust the exposure with my right thumb while I am either looking through the EVF or the LCD while composing the image.
Family came to visit this weekend and Misty got a bath before they arrived. She was sitting in my rocking chair after being partially blow dried when I took her picture. She has little patience for the blow dryer so usually escapes before being totally dry. That is OK in the summer since she goes and lays in the sun, but that doesn’t work in the winter.
