1.5.2.1. ISO setting wheel
Allows you to fine tune the ISO setting. The peculiarity of this control is that the values change slowly at the lower values and in larger steps at the higher ones.
1.5.2.2. ISO setting switch
This switch helps you to change the ISO values in half steps. Each successive step increases the value of the previous step by 50%.
1.5.2.3. Exposure mode button
Pressing this button switches the exposure mode to automatic.
1.5.2.4. Shutter speed switch
The switch has three buttons with arrow icons. The up arrow increases the shutter speed by about half a stop, leaving a shutter speed multiple of the frame rate. The down arrow decreases the shutter speed by about half a stop, leaving a shutter speed that is a multiple of your frame rate. If the shutter speed must have a fractional denominator value in order to maintain the multiplicity, the fractional part is discarded. I.e. in the case of 25 fps frame rate, after 1/25 the next shutter speed will be 1/37, not 1/37.5.
The right arrow to the right switches the multiplicity modes. There are a total of three modes of magnification: 24, 25 and 30. In situations where a frequency other than these three is selected, all three modes will be available to be switched by the right arrow. When 24 fps is selected it means that 24 fps is the main mode, and the right arrow makes the other two modes available. In multiples of 25 (25 and 50 fps), only one mode is available to the right - multiples of 30.
The frame rate modes are a tribute to the tradition when shutter speed was determined by the angle of the shutter. The 25 and 30-frame rate modes are an attempt to help get rid of incandescent flicker. 25 for 50 Hz grid (Europe and Russia), 30 for 60 Hz grid (USA).
In the case of incandescent flicker, you must keep in mind that the multiplicity mode helps up to a certain limit, usually not shorter than 1/100. To properly fight the flicker of incandescent lamps, you should choose not only a shutter speed that is a multiple of the mains frequency, but also a frame rate. For Russia and Europe, it is 25 fps and multiples of that. For the U.S. it's 30 fps and multiples of that.
The next thing to keep in mind is that LED lights can have absolutely any flicker frequency. And here the shutter speed is probably not helpful. Here we are talking about the right choice of luminaires.
1.5.2.5. Quick access buttons for exposure control
There are two buttons for quick access to exposure control: zebra and false color. Both types of exposure control can`t be activated at the same time, each next one disables the previous one.
Note that these buttons do not overwrite the settings selected in the menu. Each subsequent session will apply the settings from the menu and reset the expo-peaking selected with these buttons.
